Why don’t birds get lost on their long migratory (遷居的) flights? Scientists have puzzled over this question for many years. Now they’re beginning to fill in the blanks.
Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly mainly by night? Tests with artificial stars have proved conclusively that certain night-flying birds are able to follow the stars in their long-distance flights.
One such bird, a warbler(鳴禽) , had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird’s cage was placed under an artificial star-filled sky at migration time. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the direction of the make-be-live stars caused a change in the direction of his flight. Scientists think that warblers, when flying in daylight, use the sun for guidance. But the stars are apparently their main means of navigation (導(dǎo)航). What do they do when the stars are hidden by clouds? Apparently, they find their way by such landmarks as mountain ranges, coast lines, and river courses. But when it’s too dark to see these, the warblers circle helplessly, unable to get their direction.
小題1:The reasons why birds don’t get lost on migratory flights__________.
A.have been known to scientists for many years
B.a(chǎn)re known by everyone
C.have only recently been discovered
D.will probably remain a mystery

Egypt: Bridging the Gap between School English and Real English
Teaching English in Egypt in general and in my town Damietta in particular, is mainly directed towards helping students to pass their final exams. Unfortunately, most teachers do not adopt a long -term approach that guarantees that their students will be able to use English outside the classroom. So students only concentrate on one skill which is writing. Thus their listening and speaking skills are disabled. What is important to them is to pass the exam which is primarily based on writing .Teachers are not only concentrated with providing their students with questions that are similar to those of the final exam, particularly General Secondary Education Certificate (GSEC) Examination, so students spend most of their time answering typical exam questions.
Most students' scores are high; a lot of students get full marks. However, few students are able to communicate in English because their role plays. As a result, a lot of students complain that they are unable to understand and talk fluently with native speakers of English.
To enable students to communicate freely and spontaneously(自然地) in English, I bring features of real communication into language practice, I always ask students about their own experiences, and suggest groups of students practice what they have learned outside the classroom. This helps lower-achieving students absorb language. Furthermore, role play is a very effective way to improve speaking skills particularly if it is connected to the experience of the students.
小題1:Who probably write this passage?
A.a(chǎn) teacherB.a(chǎn) governorC.a(chǎn) studentD.a(chǎn) reporter
小題2:In Egypt, the students only concentrate on ------
A.listening skillB.speaking skillC.reading skillD.writing skill
小題3:The teachers question their students based on -------
A.what they learn in the class
B.What their parents expect
C.The questions that are similar to those of GSEC
D.The ability that will be used outside the classroom
小題4:Which of the following statements is true according to the passage?
A.Most of the students can't get high marks but can communicate with the native speakers of English.
B. Communicating skill is more important than writing skill.
C.Role play connected to the speaker's experience is more effective
in improving his skill.
D.The lower--achieving students can do better in speaking skill than the upper achieving students.
小題5:Who will responsible for the gap between school English and real English?
A.Their parentsB.The studentsC.The schoolD.The education sys tem

You've heard of the fat suit and the pregnancy suit;now meet AGNES—the old person suit.
AGNES stands for “Age Gain Now Empathy(換位體驗(yàn)) System” and was designed by researchers at MIT's AgeLab to let you know what it feels like—physically—to be 75 years old.“The business of old age demands new tools,”said Joseph Coughlin,director of the AgeLab.“While focus groups and observations and surveys can help you understand what the older consumer needs and wants,young marketers never get that‘Ah ha!’moment of having difficulty opening a jar, or getting in and out of a car.That’s what AGNES provides.”
Coughlin and his team carefully adjusted the suit to make the wearer just as uncomfortable as an old person who has spent a lifetime eating poorly and not doing much exercise.Special shoes provide a feeling of imbalance,while braces on the knees and elbows limit joint mobility.Gloves give the feeling of decreased strength and mobility in the hands and wrists,and earplugs make it difficult to hear high—pitched sounds and soft tones.A helmet with straps(帶)attached to it presses the spine(脊柱),and more straps attached to the shoes decrease hamstring flexibility, and shortens the wearer's step.
AGNES has been used most recently by a group of students working on a design of an updated walker.By wearing the suit they could see for themselves what design and materials would make the most sense for a physically limited older person.Coughlin said the suit has also been used by clothing companies,car companies and retail goods companies to help them understand the limitations of an older consumer.
“AGNES is not the destiny of everybody,” he said.“She is a badly behaved lady who didn't eat and exercise very well.A secondary benefit we’ve found with AGNES is that it has become a powerful tool to get younger people to invest in their long-term health.”
小題1:AGNES has been developed to       
A.make the users more comfortable
B.1et us understand old people better
C.help old people move more quickly
D.produce new tools for the old-age business
小題2:“An updated walker”(underlined)most likely refers to    
A.someone who travels a lot
B.a(chǎn) physically limited old person
C.some equipment that helps old people walk
D.a(chǎn) company whose service involves old people
小題3:Which may be a fact resulting from the “secondary benefit” of AGNES?
A.Young people respect old people.
B.Old-age business improves their service
C.Old people eat and exercise well.
D.Young people eat and exercise well.

Testing has replaced teaching in most public schools. My own children's school week is framed by pretests, drills, tests, and retests. They know that the best way to read a textbook is to look at the questions at the end of the chapter and then skim the text for the answers. I believe that my daughter Erica, who gets excellent marks, has never read a chapter of any of her school textbooks all the way through. And teachers are often heard to state proudly and openly that they teach to the mandated (國家指定的) state test.
Teaching to the test is a curious phenomenon. Instead of deciding what skills students ought to learn, helping students learn them, and then using some reasonable methods of assessment to discover whether students have mastered the skills, teachers are encouraged to reverse the process. First, one looks at a commercially available test. Then, one distills (提取) the skills needed not to master reading, say, or math, but to do well on the test. Finally, the test skills are taught.
The ability to read or write or calculate might infer the ability to do reasonably well on standardized tests. However, neither reading nor writing develops simply through being taught to take tests. We must be careful to avoid mistaking preparation for a test of a skill with the acquisition of that skill. Too many discussions of the basics of skills make this fundamental confusion because people are test-centered rather than concerned with the nature and quality of what is taught.
Recently, many schools have faced what could be called the crisis of comprehension or, in simple terms, the phenomenon of students with phonic and grammar skills still being unable to understand what they read. These students are capable of taking tests and filling in workbooks. However, they have little or no experience reading or thinking, and talking about what they read. They know the details but can't see or understand the whole. They are taught to be so concerned with grade that they have' no time or ease of mind to think about meaning, and reread things if necessary.
小題1:As is indicated in the second paragraph, the author finds it strange that __.
A.tests are used to assess students' skills
B.skills are determined before tests are set
C.teaching is aimed to prepare students for tests
D.teachers use some reasonable methods of assessment
小題2:The crisis of comprehension most probably results from __.
A.students' poor phonic and grammar skills
B.teaching that takes up much of students' free time
C.teaching that emphasizes details rather than the whole
D.students' lack of ability to think about what they read
小題3:According to the author, we can infer that __.
A.the basics of skills have been discussed too much
B.the nature and quality of what is taught are fully concerned
C.skills in general are not only useless but often mislead students
D.doing well in a test does not necessarily mean acquiring the skill

American beekeeping operations have been hit hard by what scientists call colony collapse disorder(C.C.D.). Almost half of their worker bees have disappeared during the past season. C.C.D. has also been reported in Israel, Europe and South America. Bees fly away from the hive and never return. Sometimes they are found dead; other times they are never found. Many crops and trees depend on pollination (授粉) by bees to help them grow.
A new report says virus may be at least partly responsible for the disorder in honey bee colonies in the United States. This virus is called Israeli acute paralysis virus. It was first identified in Israel in 2004. Ian Lipkin at Columbia University in New York and a team reported the new findings in Science magazine. Doctor Lipkin says the virus may not be the only cause. He says it may work with other causes to produce the collapse disorder.
The team found the virus in colonies with the help of a map of honey bee genes that was published last year. They examined thirty colonies affected by the disorder. They found evidence of the virus in twenty–five of them, and in one healthy colony. The next step is further testing of healthy hives.
The researchers suggested that the United States may have imported the disorder in bees from Australia. They say the bees may carry the virus but not be affected.
The idea is that unlike many American bees, the ability of Australian bees to fight disease has not been hurt by the varroa mite(全球性的蜂虱). This insect attacks honey bees, which could make the disorder more likely to affect a hive. Australian bee producers reject these suspicions.
And some researchers suspect that bee production in the United States is down mainly because of the weather. Honey bees gather nectar(花蜜) from flowers and trees. The sweet liquid gives them food and material to make honey. But cold weather this spring in the Midwest reduced the flow of nectar in many flowers. Many bees may have starved. Dry weather in areas of the country could also be playing a part.
Wayne Esaias is a NASA space agency scientist who keeps bees in his free time. He lives in central Maryland, where he has found that flowers are blooming a month earlier than they did in 1970, which may be partly responsible for the disorder. Wayne Esaias is organizing a group of beekeepers to document nectar flow around the country.
小題1:The researchers found the virus ______.
A.with the help of colony collapse disorder
B.by researching the causes of bee death
C.with the help of a map of honey bee genes
D.with the help of a scientist of NASA
小題2:What is the passage mainly about?
A.American beekeeping industry has been strongly influenced by the bee disorder.
B.Studies are being carried out on the causes of the bee disorder, but questions remain.
C.How the causes of the bee disorder in U.S have been found.
D.The bee production in U.S is down because of Israeli acute paralysis virus.
小題3:How many possibilities may be involved in the bee disorder according to the passage?
A.Three.B.Four.C.Five.D.Six.
小題4:We can infer from the passage that ______.
A.Israeli acute paralysis virus should be responsible for the disorder
B.the solution to the bee disorder will be found eventually
C.American bees are more likely to defend themselves than Australian bees
D.the crop and plant production in U.S may be influenced by the bee disorder

“If you talk to the plants, they will grow faster and the effect is even better if you’re a woman.” Researchers at Royal Horticultural Society carried out an experient to find that the voice of a woman gardener makes plants grow faster.
The experiment lasted a month and by the end of the study scientists managed to discover that tomato plants grew up two inches taller when women gardeners talked to them instead of male.
Sarah Darwin was the one making the plants registered the best growth. Her voice was the most “inspiring” for plants than those of nine other gardeners when reading a passage from The Origin of Species. The great-great-granddaughter of the famous botanist(植物學(xué)家) Charles Darwin found that her plant grew about two inches taller than the plant of the best male gardener.
Colin Crosbie, Garden Superintendent at RHS, said that the finding cannot yet be explained. He assumes that women have a greater range of pitch(音高) and tone(音調(diào)) which might have a certain effect on the sound waves that reach the plant. “Sound waves are an environmental effect just like rain or light ,”said Mr Grosbie.
The study began in April at RHS Garden Wisley in Survey. Scientists started with open auditions(聽力) for the people who were asked to record passages from John Wyndham's The Day of the Triffids, Shakespeare’s A Midsummer's Night Dream and Darwin's The Origin of Species.
Afterwards researchers selected a number of different voices and played them to 10 tomato plants during a period of a month. Each plant had headphones(耳機(jī)) connected to it. Through the headphones the sound waves could hit the plants. It was discovered that plants that “l(fā)istened” to female voices on average grew taller by an inch in comparison to plants that heard male voices.
Miss Darwin said, “I think it is an honor to have a voice that can make tomatoes grow, and especially fitting because for a number of years I have been studying wild tomatoes from the Galapagos Island at the Natural History Museum in London.”
小題1:What does the passage talk about?
A.Plants enjoy men’s voices than women’s.
B.A botanical experiment in a museum.
C.Voice’s influence on plant growing.
D.Strange phenomenon(現(xiàn)象) at Royal Horticultural Society.
小題2:What does the underlined sentence in paragraph 4 mean?
A.Plants need sound as well as rain and light.
B.Sound is basic for the plant to grow.
C.Sound has a good effect as rain or light does.
D.Plants can’t live without sound, rain or light.
小題3:Sarah Darwin is most likely a (an)_____.
A.botanistB.gardenerC.a(chǎn)stronomerD.environmentalist
小題4:What can we learn from the passage?
A.The experiment ended in May.
B.Scientist can explain the findings clearly.
C.Plants enjoy listening to the passages from masterpieces.
D.The findings are of great importance to human beings.

Although April did not bring us the rains we all hoped for, and although the Central Valley doesn’t generally experience the sound and lightning that can go with those rains, it’s still important for parents to be able to answer the youthful questions about thunder and lightning.
The reason these two wonders of nature are so difficult for many adults to explain to children is that they are not very well understood by adults themselves. For example, did you know that the lightning we see flashing down to the earth from a cloud is actually flashing up to a cloud from the earth? Our eyes trick us into thinking we see a downward motion when it’s actually the other way around. But then, if we believed only what we think and we see, we’d still insist that the sun rises in the morning and sets at night.
Most lightning flashes take place inside a cloud, and only a relative few can be seen jumping between two clouds or between earth and a cloud. But, with about 2,000 thunderstorms taking place above the earth every minute of the day and night, there’s enough activity to produce about 100 lightning strikes on earth every second.
Parents can use thunder and lightning to help their children learn more about the world around them. When children understand that the light of the lightning flashing reaches their eyes almost at the same moment, but the sound of the thunder takes about 5 seconds to travel just one mile, they can begin to time the interval (間隔) between the flash and the crash to learn how lose they were to the actual spark (閃光).
小題1:According to the author, in the area of the Central Valley____.
A.rains usually come without thunder and lightning.
B.it is usually dry in April
C.children pay no attention to the two natural wonders.
D.parents are not interested in thunder and lightning.
小題2:We believe that lightning is a downward motion because_______.
A.we were taught so by our parents from our childhood.
B.we are taken in by our sense of vision.
C.it is a common natural sight.
D.it is a truth proved by science.
小題3:What is TRUE about lightning according to the passage?
A.Only a small number of lightning flashes occur on earth.
B.Lightning flashes usually jump from one cloud to another.
C.Lightning travels 5 times faster than thunder.
D.There are far more lightning strikes occurring on earth than we can imagine.
小題4:The underlined word “activity”  is most closely related to the word (s) _____.
A.cloudB.lightning strikesC.lightning flashesD.thunderstorms
小題5:It can be concluded from the passage that _______.
A.we should not believe what we see or hear.
B.things moving downward are more noticeable.
C.people sometimes may have wrong ideas about ordinary phenomena.
D.a(chǎn)dults are not as good as children in observing certain natural phenomena.

Memory is the ability to keep track of things that have happened in the past. Memory really is learning. One needs memory to ride a bicycle. A dog needs to remember if it is to come when called.
Memory is said to be stored in the brain as a “memory trace(記憶痕).” What makes up this trace is not known. Some scientists believe that certain chemical substances may carry certain memories. For example, one substance, when given to rats, causes them to fear the dark.
Other research into memory has to do with how the brain works. Psychologists use three means to find out how a person remembers. For example, give a person a grocery list. Let the person memorize the list, then put it away. The most natural way to find out how much a person remembers of the grocery list is to ask what he or she remembers. This is called the method of recall. Another method is called recognition. Give the person another grocery list. Ask him or her to choose items on the first list from the items that are on only the second list. Often a person will be able to recognize things that he or she cannot recall. A third method of finding how much a person remembers is called relearning. Here the person is asked to read over the first list. The person will probably learn the list the second time faster than he did the first time. The difference in the time it takes to relearn the list is thought of as a measure of how much a person has remembered.
One way of remembering something is to repeat it many times. Interest is very important. Boring lists of facts are much more difficult to remember than something that we understand and are interested in. Motivation, or wanting to do something, is also important. Motivation is linked with reward. For example, a hungry animal quickly learns how to do something if that action gets the animal food. In humans, wanting to learn is often motivation. The praise of a teacher or the knowledge that an answer is correct is rewarding.
小題1:We can learn from the 2nd paragraph that ___________       .
A.bad memories may cause rats to fear the dark
B.it is hard to tell what a memory trace consists of
C.chemical substances carry certain memories
D.memory is stored in the brain as a substance
小題2:The way to pick out the items on the first list from the second is known as ________ .
A.recognitionB.recallC.memorizationD.relearning
小題3:What is considered as a measure of how much one has remembered?
A.The length of the list.
B.The type of list items.
C.The time difference of relearning.
D.The time difference of brain working.
小題4:A good way to train an animal to do something quickly is to ________.
A.make the action easyB.praise it in words
C.reward it with foodD.weaken its motivation
