A recent online poll (民意調(diào)查) asked kids what they hated most about school. “Classes are boring” came in first. “Too much homework” was a close second. Since all activities remain interesting for only so long, too much homework can lead to ennui. So, why are some kids getting homework overload? Teachers give two reasons. First, they say, the government now requires schools to meet higher-than-ever achievement goals for students. If students don’ t succeed, the school faces punishment. Second, many parents want their children to be able to get into the best colleges and universities. These parents believe homework is a way to ensure that students are learning as much as possible.
People who favor homework argue that it can have many beneficial effects. They claim it can help students develop good study habits. Homework can help students recognize that learning can occur at home as well as at school. It can help develop their independent learning and responsible character traits(性格特征).
But studies show that middle school students doing 60 to 90 minutes of homework a night are doing just as well in school as those doing more than 90 minutes. And homework can have negative effects. Homework can deny students access to leisure(休閑) activities that also teach important skills. For example, sports teams teach cooperation and leadership, in addition to helping kids stay physically active. Another problem with too much homework is that parents can get too involved. They can put too much pressure on their kids.
So what should be done? Good homework assignments in the proper amount will have positive effects. Too much homework, however, will have negative effects. The bottom line: Students in grades three through six should do no more than 30 to 60 minutes of homework each night.
小題1:The underline word “ennui” in Paragraph 2 can be replaced by “______” .
A.relaxationB.fancyC.boredomD.intelligence
小題2: According to Paragraph 1, the kids are given much homework because ________.
A.schools are evaluated in terms of students’ achievement.
B.the government doesn’t take the problem seriously
C.it is a good way to improve the students’ ability
D.time will be made full use of in this way
小題3:Those who are in favor of homework think that _______.
A.homework helps students to succeed
B.it’s good for kids to help each other in learning
C.parents are a great help when kids do homework at home
D.homework helps children to learn independently
小題4: Which of the following is NOT a negative effect of too much homework?
A.Kids have little time to do leisure activities.
B.There is a lack of sleeping time.
C.The chances of learning other skills are lost.
D.Kids are under pressure from their parents.

In our life, we have rarely expressed our gratitude to the one who’d lived those years with us.In fact, we don’t have to wait for anniversaries to thank the ones close to us—the ones so easily overlooked. If I have learned anything about giving thanks, it is this: give it now!While your feeling of appreciation is alive and sincere, act on it. Saying thanks is such an easy way to add to the world’s happiness.
Saying thanks not only brightens someone else’s world, but it also brightens yours. If you’re feeling left out, unloved or unappreciated, try reaching out to others. It may be just the medicine you need.
Of course, there are times when you can’t express gratitude immediately. In that case don’t let embarrassment sink you into silence—speak up the first time you have the chance.
Once a young minister, Mark Brian, was sent to a remote parish of Kwakiutl Indians in British Columbia. He had been told that the Indians did not have a word for thank you. But Brian soon found that these people had exceptional generosity. Instead of saying thanks, it is their custom to return every favor with a favor of their own, and every kindness with an equal or superior kindness. They do their thanks.
I wonder if we had no words in our vocabulary for thank you, would we do a better job of communicating our gratitude? Would we be more responsive, more sensitive and more caring?
Thankfulness sets in motion a chain of reaction that transforms people all around us—including ourselves, for no one ever misunderstands the melody of a grateful heart.
小題1:In the first paragraph the writer mainly encourages us       .
A.to express our sincere thanks timely to those around us
B.never to overlook our close friends in daily life
C.to wait for a proper occasion to show our gratitude
D.to increase the world’s happiness by saying thanks
小題2:When we say something for what others do for us, it ______.
A.is good for both us and people who help us
B.benefits the people who do something for us
C.wastes our and our friends’ time at the same time
D.does harm to both us and people who help us
小題3:According to the writer,        could be the best way to prevent ourselves from being left out.
A.seeing a doctor to find the right medicine we need
B.expressing our gratitude in an easy way
C.speaking up the moment we have the chance
D.showing others actively we are willing to help them
小題4:Mark Brain’s story is mentioned in the passage in order to show the fact that       .
A.the Indians didn’t have any words for appreciation
B.the Indians were particularly generous to others
C.some people may express their gratitude through different approaches
D.Mark Brain set the Indians an example to show saying thanks is very important

University is generally regarded as one of the most important times in a person’s life, yet the function of this institution continues to arouse debate. Many believe that arts subjects are  too easy, that practical skills are more useful and that a chosen subject for study should be clearly linked to a career. However, this view is far too simplistic. Arts subjects are very difficult. They can prepare students for any number of careers as well as allowing the student to take time to make a decision. The function of the modern university is to cater to different types of student.
Arts subjects are not easy. For example, a degree in Literature is not an easy option. No question in a Literature class has a single, simple answer. Debate is conducted in a spirit of openness, texts are very closely analyzed and skills in close reading are developed. Literature is about language, our primary means of communication. Arts subjects require the same concentrated study as any other subject.
Arts subjects can prepare students for any number of careers. A degree in an arts subject teaches skills in well organized debates and defence of a position through the provision of evidence. These are applicable to many types of career. Law, for example. The point is that an undergraduate degree in any Arts subject trains the student in analysis and structure. Therefore, Arts graduates can pursue any number of careers.
Arts subjects allow the student to take time to choose a career. Love of the subject for its own sake may well be the initial motivation for the Arts undergraduate but because the subject they have chosen is not so clearly linked to a career they have time to reflect, making a decision only when they are absolutely certain. Students who pursue Arts subjects therefore have the leisure to make a carefully considered choice.
In conclusion, it is clear that Arts subjects are not a waste of time. They are flexible when it comes to relating them to a career and they allow the student to discover an appropriate career path. Many industries now acknowledge that a degree in Literature can be just as valuable as any other subject, especially when it is evident that Arts graduates tend to think more creatively. Not all undergraduates have clearly defined goals and not all subjects can be simply matched to a career. Acknowledging this difference should be the main function of a modern university
小題1: What does the author mainly argue in this article?   
A.Universities should be aware of diversityB.Universities should focus on practical courses.

D.They need to offer more arts courses.
小題3:The author suggests that technical subjects ____________.  
A.a(chǎn)re more important than arts subjects.B.a(chǎn)re more useful to the modern world.
C.have equal value to arts subjects.D.a(chǎn)re not as important as arts subjects.

Can people change their skin color without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin color.
The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.
Scientists have changed the color of a dark-striped zebrafish(斑馬魚) to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebrafish skin color is determined by pigment cells, which contain melanin (黑色素). The number, size and darkness of melanin per pigment cell determine skin color.
It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation (變異) in the gene for melanin production. This results in less pigmented skin.
However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebrafish genes.
Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun (太陽光紫外線), which can cause skin cancer.
But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.
Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color, said Cheng.
The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin color without damaging it like chemical treatment did on Michael Jackson.
小題1: The passage mainly tells us that ________.
A.people can not change their skin color without any pain
B.the new discovery could lead to research into ways to change skin color safely
C.pop king Michael Jackson often changed his skin color as he liked
D.scientists have found out that people’s skin color is determined by the gene
小題2: It can be inferred from the passage that ________.
A.nowadays people who want to change their skin color have to suffer a lot from the damage caused by the chemical treatment
B.Europeans and Africans have the same gene
C.the new discovery could help to find medical treatments for skin cancer
D.there are two kinds of genes
小題3:Scientists have done an experiment on a dark-striped zebrafish in order to ________.
A.find the different genes of humans’
B.prove the humans’ skin color is determined by the pigment gene
C.find out the reason why the Africans’ skin color is dark
D.find out the ways of changing people’s skin color
小題4:The reason why Europeans are light-skinned is probably that _____
A.they are born light-skinned people
B.light-skinned Europeans have mutation in the gene for melanin production
C.they have fewer activities outside
D.they pay much attention to protecting their skin
小題5:The writer’s attitude towards the discovery is ________.
A.neutral(中立的)B.negativeC.positiveD.indifferent(冷漠)

Recently there was a major discovery in the scientific research — the mapping of all DNA in a human gene(基因) is complete. Couple of years ago, this seems an impossible task for scientist to accomplish. All this progress in science leads us to believe that the day, when the human being will be cloned, is not far away. Human cloning has always been a topic of argument, in terms of morality(道德) or religion.
Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning. If the clone was free of genetic limitations, then the other clone would be as well. The latter could be inserted in the woman and allowed to ripen to term. Moreover, cloning would enable women, who can’t get pregnant, to have children of their own.
Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs. This surely would be greatly beneficial to millions of unfortunate people around the world that are expected to lose their lives due to failure of single (or more) organ(s). It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.
Arguments against cloning are also on a perfectly practical side. Primarily, I believe that cloning would step in the normal “cycle” of life. There would be a large number of same genes, which reduce the chances of improvement, and, in turn, development — the fundamental reason how living things naturally adapt to the ever-changing environment. Life processes failing to do so might result in untimely disappearance. Furthermore, cloning would make the uniqueness that each one of us possesses disappear, thus leading to creation of genetically engineered groups of people for specific purposes, and chances are that those individuals would be regarded as “objects” rather than people in the society.
Scientists haven’t 100% guaranteed that the first cloned humans will be normal. Thus, this could result in introduction of additional limitations in the human “gene-pool”.
Regarding such arguable topics in “black or white” approach seems very innocent to me personally. We should rather try to look at all “shades” of it. I believe that cloning is only legal if its purpose is for cloning organs; not humans. Then we could regard this as for “saving life” instead of “creating life”. I believe cloning humans is morally and socially unacceptable.
小題1:   Which of the following is true according to the passage?
A.Genetic limitation will be beneficial for some women
B.A large number of genes will prevent us from developing
C.Prohibition(禁止) of cloning might limit the freedom of scientists
D.First cloned humans might be normal according to scientists
小題2:What’s the author’s opinion on cloning?
A.Cloning should be entirely banned
B.Cloning should be used in creating life
C.Cloning will take away the right to reproduce
D.Cloning is acceptable if it is used for cloning organs

A lazy Susan is an addition to a table that is designed to assist in moving food from one person to another while dining. This is achieved through the use of a turntable (轉(zhuǎn)盤), which usually moves the food in a circle when it is pushed by those at the table. In this way, the food never has to be picked up and passed around the table. Instead, it remains in place on the lazy Susan.
A lazy Susan may also be a part of a kitchen cabinet (櫥柜). In this sense, the lazy Susan is a type of shelving unit within the cabinet that is able to turn around its axis(軸心) . One may turn the lazy Susan in order to find certain goods in storage. From the outside, a lazy Susan appears to be two cabinets that are located at a right angle (直角) to each another. When one of these cabinets is pushed, however, both doors move and the lazy Susan is revealed inside.
It is believed that Thomas Jefferson invented the lazy Susan in the 18th century, though it was called “dumbwaiter” at that time. It is said that Jefferson invented the lazy Susan because his daughter complained she was always served last at table and, as a result, never found herself full when leaving the table. Others believe that Thomas Edison was the inventor, as he is believed to have invented the turntable for his phonograph (留聲機). The turntable may have developed into the lazy Susan later.
Regardless of who invented it, it wasn’t until 1917 that the term “l(fā)azy Susan” was used in an advertisement for the invention. In Britain, however, the term “dumbwaiter” is still used rather than “l(fā)azy Susan”. The reason for the naming of it is still a mystery. One theory is that it was named after either Jefferson’s or Edison’s daughter, both of whom were named Susan.
小題1:What is a “l(fā)azy Susan”?
A.A waitressB.A convenient toolC.A tableD.A cabinet
小題2:According to those who believed Thomas Jefferson invented the lazy Susan, _______.
A.his daughter was very lazyB.the lazy Susan didn’t exist until the 18th century
C.Thomas Edison was his friendD.Thomas Edison didn’t invent the phonograph
小題3:We can learn from the last paragraph that ___________.
A.the lazy Susan can work by itself
B.the lazy Susan was named after Thomas Edison’s daughter
C.how the lazy Susan got its name remains unknown
D.the lazy Susan was invented in Britain

Although many butterflies remain to be decreasing in the long run, last year three quarters of endangered species saw an increase in number, including some rare species.
Experts said the improvement in the butterflies’ fortunes was likely to be the result of effective action on protection, such as leaving open wetland in woods where flowers can grow, and better weather in 2010 after three damaging wet summers.
Dr Tom Brereton said butterflies are extremely sensitive to changes in the weather. Last year saw a warm summer for successful feeding, which helped a number of butterflies in some way.
He even said climate change could be benefiting some butterfly species but many other butterfly species suffer from it. For example, the mountain ringlet suffers as it needs cold climates. And at the same time, the change is too rapid for most to get used to.
In the long run butterfly numbers have continued to drop, with three quarters of the nearly 60 species found in Britain seeing numbers fall in recent decades and nearly half of them seriously threatened.
The Lulworth skipper, one of the UK’s rarest butterflies, had its worst year since 1976, and there are people worrying that changing the environment to benefit other species may be harming this kind of butterfly. Wild flowers have been grown in some places to help other butterflies but the Lulworth skipper needs long grass and wild areas. Meadow browns, the country’s most common species, also had the worst year on record. Some other kinds of butterflies also had a bad year.
However, in the short term many butterflies saw an increase in number in 2010 compared to 2009 levels.

小題1:Which was a reason for the increase in the number of the butterflies last year?
A.The protection of humans.B.A wet summer.
C.Changes in the butterflies’ habits.D.The decrease in wetland in woods.
小題2:We can learn from Dr Tom Brereton’s words that       .
A.the mountain ringlet can quickly adapt to climate change
B.butterflies can help slow down climate change
C.climate change can be both beneficial and harmful to butterflies
D.other kinds of animals also suffer from climate change
小題3:What is most likely to be discussed in the following paragraph?
A.Why some butterflies decreased in number in 2010.
B.How to protect butterflies in the coming winter.
C.Effects of climate change on butterflies.
D.Examples of butterflies that have increased in number.
小題4:What is the passage mainly about?
A.Some butterflies in Britain have had a good year.
B.Butterflies in Britain have different habits.
C.Butterflies are well protected in Britain.
D.Butterflies are disappearing from Britain.
