Most of us seem to reach our peak of alertness (警覺) around noon. Soon after that, alertness declines, and sleepiness may set in by mid-afternoon.
Your short-term memory is best during the morning—in fact, about 15 percent more efficient than at any other time of day. So, students, take notice: when you are faced with a morning exam, it really does pay to review your notes right before the test is given.
However, long-term memory is different. Afternoon is the best time for learning materials that you want to recall days, weeks or months later. Politicians, business executives or others who must learn speeches would be smart to do their memorizing during that time of day. You should try to do most of your studying in the afternoon, rather than late at night. Many students believe they memorize better while burning the midnight oil because their short-term recall is better during the early hours of the morning than in the afternoon. But short-term memory won’t help them much several days later, when they face the exam.
By contrast, we tend to do best on tasks related to the process of knowing, understanding, and learning numbers during the morning hours.
What about sports? During afternoon and early evening, you’re able to react the quickest to an outside stimulus—like a baseball speeding toward you. Studies have also shown that late in the day, when your body temperature is peaking, you will consider PE easier and less tiring—whether it actually is or not. That means you are more likely to work harder during a late afternoon or early evening workout, and therefore benefit more from it.  
In fact, all of your senses—taste, sight, hearing, touch and smell—may be at their keenest during late afternoon and early evening. That could be why dinner usually tastes better to us than breakfast.
While all of us follow the same general pattern of ups and downs, the exact timing varies from person to person. It all depends on how your “biological” day is structured. Each of us can increase our knowledge about our individual rhythms. Learn how to listen to the inner beats of your body; let them set the pace of your day. You will live a healthier and happier life.

Kindergarten outside? Yes, indeed. It’s part of a growing worldwide trend toward outdoor education. The schools are called forest kindergartens.
The numbers are small so far in the U.S., but the idea is well established in Europe, with schools in Scotland, England, and Switzerland. By far the most such schools are in Germany, which has more than 400 forest kindergartens.
Some schools feature several hours of outdoor schooling. This is certainly the case with the Waldorf School of Saratoga Springs. Children there will be venturing out on the nearby Hemlock Trail to learn more about the natural world. Some lessons are focused on nature; others are academic topics delivered in a natural setting. In all cases, students are active-not sitting at desks or on mats on the floor but walking, running, jumping, solving problems like how to get the mud off the bottoms of their shoes before their parents find out.
Seriously, the focus is on activity at these schools. Studies have shown that children’s immune systems actually get stronger after all of the outdoor activity, and that graduates of forest kindergartens show a higher ability to learn when they progress through their academic careers.
Other schools are all outdoors, all the time. This is the case with the Cedar Song Nature School, on Vashon Island, Washington. Students at this school spend their whole three–hour day outdoors, in a private five-acre forest, doing all kinds of physical activities.
At these forest kindergartens, students learn science by observing and doing it, learn math by applying it to the natural world around them, learn letters and words by putting them together using sights and sounds. These students learn how to get along with one another, individually and in a group. They also develop healthy levels of self-confidence.
Nowadays many children become obese(肥胖的) because of sedentary(久坐的) activities like watching television and playing video games. These outdoor schools give children chances to learn just as much, if not more, from opening their eyes to the real world around them.
小題1:What do we know about forest kindergartens?
A.The first one was created in England.B.They are very popular in Germany.
C.There are 400 all over the world.D.Their number is huge in the U.S.
小題2:What is special about forest kindergartens?
A.Kids learn more than those at ordinary kindergartens.
B.Students go outside when weather permits.
C.They value activity very much.
D.They are situated in forests.
小題3:The main difference between the Waldorf School and Cedar Song Nature School lies in______.
A.the subjectsB.the activities
C.the outdoor timeD.the teaching methods
小題4:Which of the following would be the best title for the text?
A.Get close to natureB.A new trend of education
C.Forest kindergartens are popularD.Outdoor education benefits kids a lot

Some wonderfully creative uses of X-rays have been in the world of art.But the most impressive one is to uncover what has been covered up.Details unfolded by an X-ray of a painting can ' t be seen any other way.For example, in the past, paintings were often repaired if small pieces of paint fell off the canvas (帆布). These repairs cannot be seen just by looking at the painting.It takes an X-ray to discover where the repairs have been made.
An X-ray of a painting is one of the best ways to tell if it was created by a famous painter or if it is a forgery(贗品).If there is a question as to whether an old master has painted a certain painting or not, X-rays are made and compared to those of paintings that are known to be original.If the brushstrokes (筆跡) , for example, are shown to be totally different than in other work done by a certain artist, then the painting is proved to be a fake copy.
Since modern paints are usually made from different materials than paints of hundreds of years ago, the image they leave on an X-ray film looks different.This is another way X-rays can be used to spot a forgery.A modem artist will try to make a forgery look hundreds of years old by painting dirty varnish on it or by using artificial means to get the varnish to look cracked.To the naked eye the forgery may look old, but when a careful study of the X-ray image is made, the deception is obvious.
It was common many years ago for an artist to finish a painting, decide it wasn't any good, and paint a completely different picture on top of it.Or artists would paint over others' work —it was their version of recycling.Taking an X-ray is the only way to find out if there is a picture underneath the picture you see with your eyes.Sometimes museums will be more interested in the painting beneath than the one on top, and will restore the older one by having the top layer painstakingly removed.
小題1:What is the main purpose of the article?
A.To provide information to police who are looking for stolen art.
B.To persuade art dealers to check for fake copies before selling art.
C.To explain how modern technology can be applied in unique ways.
D.To help artists restore damaged artwork to its original appearance.
小題2:According to the passage,X-rays are used to ______.
A.make repairs on paintings in the past
B.identify the authenticity of an artwork
C.change the materials of a forgery
D.remove the recyclable paints
小題3:In Paragraph 3, the word "deception" probably means ______.
A.comparisonB.drawbackC.trickeryD.judgement
小題4:Which is the best title for the passage?
A.X-ray Detectives
B.Creative Uses of Technology

Every year in the first week of English class, some students inform me that writing is too hard. They never write, unless homework requires it. They find the writing process painful and difficult.
How awful it is to be able to speak in a language but not to write in it, especially with its rich vocabulary. Being able to speak but not write is like living in an enormous mansion and never leaving one small room. When I meet students who think they can’t write, I know, as a teacher my duty is to show them the rest of the rooms. My task is to build fluency and accuracy while providing the opportunity in any writing activity to enhance(增強)the moral and emotional development of my students.
One great way to do this is by having students write in a journal in class every day.
Writing ability is like strength training. Writing needs to be done just like exercise; just as muscles grow stronger with exercise, writing skills improve quickly with writing practice daily. I often see a rise in student confidence and performance after only a few weeks of journal writing.
Expressing oneself in writing is one of the most important skills I teach to strengthen the whole students. When my students practice journal writing, they are practicing for their future academic, political, and emotional lives. They build skills so that some say they might write a great novel, a piece of sorely needed legislation(法規(guī)), or the perfect love letter. That they write in their journals every day puts them a step closer to fluency, eloquence(雄辯)and command of the language.
小題1:What is the purpose of the passage?
A.To encourage students to keep a journal every day.
B.To analyze students’ problems in learning languages.
C.To stress the importance of writing in language learning.
D.To introduce an effective way of improving students’ writing.
小題2:The underlined phrase “an enormous mansion” in Paragraph 2 refers to students’       .
A.writing opportunityB.large house
C.large vocabularyD.emotional life
小題3:In the author’s view, what can students benefit from the journal writing?
A.It is beneficial to students’ future career.
B.It can make students more emotional.
C.It is helpful to students’ homework.
D.It can enlarge students’ vocabulary.

Much of the water we use comes from snow. Melting snow provides water for rivers, electric power centers and agricultural crops. In the western United States, mountain snow provides up to 75% of all surface water supplies.
Snowfall helps to protect plants and some wild animals from cold, winter weather. Fresh snow is made largely of air trapped among the snow crystals. Because the air has trouble moving, the movement of heat is greatly reduced.
Snow also is known to influence the movement of sound waves. When there is fresh snow on the ground, the surface of the snow takes in, or absorbs, sound waves. However, snow can become hard and flat as it becomes older or if there have been strong winds. Then the snow's surface will help to send back sound waves. Under these conditions, sounds may seem clearer and travel farther.
Generally, the color of snow and ice appears white. This is because the light we see from the sun is white. Most natural materials take in some sunlight. This gives them their color. However, when light travels from air to snow, some light is sent back, or reflected. Snow crystals have many surfaces to reflect sunlight. Yet the snow does take in a little sunlight. It is this light that gives snow its white appearance.
Sometimes, snow or ice may appear to be blue. The blue light is the product of a long travel path through the snow or ice. In simple terms, think of snow or ice as a filter. A filter is designed to reject some substances, while permitting others to pass through. In the case of snow, all the light makes it through if the snow is only a centimeter thick. If it is a meter or more thick, however, blue light often can be seen.
小題1:How many functions of snow are discussed in the passage?
A.OneB.TwoC.ThreeD.Four
小題2:Why does snowfall help to protect plants from cold?
A.Because snow crystals contain heat.
B.Because snow crystals have air in them.
C.Because snow crystals are easy to blow away.
D.Because snow crystals send out heat when melting.
小題3:It can be inferred that ______.
A.hard snow is better in protecting wild animals than fresh snow
B.fresh snow is better in sending sound waves than hard snow
C.fresh snow is better in taking in sound waves than hard snow
D.hard snow provides less water than fresh snow
小題4:The color of snow and ice appears white because snow crystals________.
A.send back none of the sunlightB.send back all of the sunlight
C.take in most of the sunlightD.take in some of the sunlight

In some countries in which there is very little rain at any time, the farmers have to irrigate their fields. Irrigation is easy enough if there is a great river near the crops, and if there is plenty of water in it. Canals carry the river water to the fields when necessary. In some seasons there may be too much water in the river, and the water may flood all the land near it. At other times the river water may not be enough for all the farmers, and then it will be difficult to irrigate the fields.
To prevent these difficulties, a dam may be built across the river. This will store water for dry seasons, and in wet seasons it will prevent the flooding of the land. A great lake will, no doubt, be formed behind the dam, and this may mean that houses and fields will be covered with water. Most people will accept that and will be ready to move to other places. Then the country can have the right amount of water at all times; more crops will be grown, there will be more food for everyone, and there will be no more floods.
Dams have been built for centuries in different parts of the world. Modern dame are usually built of concrete(混凝土)but earth dams were used in India and Sri Lanka about 2500 years ago. There was another across the River Tigris very long ago, and large numbers of irrigation canals were made in Iraq to irrigate the land. The Romans were great dam-builders and there was also a famous dam at Ma’ rubin Arabia.
We cannot use sea water for irrigation; the salt will not allow the crops to grow. Fresh water is always needed, and it is very difficult and costly to make fresh water from sea water. This is done in a few countries, but the fresh water is for drinking. There is not enough at present for irrigation. Perhaps a scientist will one day invent a cheaper way of producing fresh water from the sea.
小題1:The first paragraph mainly talks about         .
A.the problems caused by river water
B.the necessity to irrigate the field
C.the water shortage in some countries
D.the canals carrying water to fields
小題2:A dam is usually built         .
A.to cover the houses and fields
B.for people to have the right amount of water at all times
C.to grow crops better
D.to form a large lake
小題3:The underlined word“that”means        .
A.a(chǎn) dam will be built across the river
B.a(chǎn) dam will store water for dry seasons
C.in wet seasons a dam will prevent the flooding of the land
D.houses and fields will be covered will water
小題4:The third paragraph suggests that        .
A.modern dams are made of concrete
B.Romans once built many great dams
C.there was too much water in 1rap in the past
D.modern dams are better than early dams

Gauri Nanda sees a wearable computer as a handbag — one that’s built out of four-inch squares and triangles of fiber, with tiny computer chips embedded (嵌入) in it. It looks, feels and weighs like your typical leather purse.
That’s where similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you’re about to leave the house, to take your wallet. It can review the weather report and suggest that you grab an umbrella. This purse can even upload your favorite songs onto your scarf.
Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. DuPont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle.
As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse.
Here’s how the bag works: You place a special radio-signal-transmitting chip on to your wallet. A similar radio in your purse picks up the signal and notifies you that you’ve forgotten to take your wallet. In turn, sensors on your purse’s handles will notify the computer that you’ve picked up the purse and are ready to go.
Already, these new kinds of wearable devices are being adopted for use in markets like auto repair, emergency services, medical monitoring — and even, increasingly, for consumers at large. Indeed, more people will want to cross that bridge in the coming years — making for a booming market for wearable computers that don’t like something out of science fiction.
小題1:Which of the following describes a wearable computer?
A.It can be washed in a washing machine.
B.It is much heavier than a leather purse.
C.It can download songs from the Internet.
D.It is made of clothes conducting electricity.
小題2:According to the passage, these new wearable computers ________________________.
A.require users to operate on the stomach
B.pick up the signals through wires and chip
C.a(chǎn)re being applied in some different areas now
D.a(chǎn)re smarter but more expensive than the old ones
小題3:What does the underlined sentence in the last paragraph mean?
A.These new wearable computers have become fashionable.
B.People would like to learn more about these new computers.
C.These new wearable computers promise to sell well in the future.
D.The idea of these purse-like computers comes from science fiction.
小題4:The purpose of the passage is ________________________________________.
A.to introduce a new kind of computerB.to explain the function of computers
C.to compare different types of computersD.to show how high technology affects our life
