C Too much TV-watching can harm children’s ability to learn and even reduce their chances of getting a college degree, new studies suggest in the latest effort to examine the effects of television on children.
One of the studies looked at nearly 400 northern California third-graders. Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedrooms TVs.
A second study, looking at nearly 1,000 grown-ups in New Zealand, found lower education levels among 26-year-olds who had watched lots of TV during childhood. But the results don’t prove that TV is the cause and don’t rule out that already poorly motivated youngsters(年轻人)may watch lots of TV.
Their study measured the TV habits of 26-year-olds between ages 5 and 15. Those with college degrees had watched an average of less than two hours of TV per weeknight during childhood, compared with an average of more than 2½ hours for those who had no education beyond high school.
In the California study, children with TVs in their rooms but no computer at home scored the lowest, while those with no bedroom TV but who had home computers scored the highest.
While this study does not prove that bedroom TV sets caused the lower scores, it adds to accumulating findings that children shouldn’t have TVs in their bedrooms.
第64题：
According to the California study, the low-scoring group might____________.
A. have watched a lot of TV
B. not be interested in math
C. be unable to go to college
D. have had computers in their bedrooms

CIn most situations, light helps us see. But nowadays humans are using too much of it so that it is in fact a kind of pollution.When it comes to looking at the night sky, too much light makes it difficult for us to watch some of life’s most wonderful sights: stars, planets and even galaxies(星系).According to scientific research, about 2, 500 stars can be seen by the human eye without using any special equipment(设备). But because of light pollution, you can only see 200 to 300 stars from today’s countryside, and no more than ten stars from a city. In most big cities, people cannot see the sky filled with stars like they did in their childhood.Light pollution affects more than just our view of sky. Research shows that lots of nighttime light can harm wildlife, too.When birds fly to another place over cities, they sometimes get lost by the brightness and fly in circles(圈) until they drop from tiredness. Sea turtles(海龟) need dark beaches for laying eggs, but they can’t find their ideal places because of those bright lights.Too much light at night may even affect human health, but scientists are not sure of that. They are still learning more.In order to prevent things from going worse, governments and some organizations are working to reduce light pollution. Many cities and towns have taken action to reduce the use of lights at night. Lights are used only when and where they are truly needed. They also shine lights down at the ground instead of up into the sky and use lower brightness levels.Hopefully, in the near future, humans can enjoy the clear and beautiful sky again and all the wildlife will live a peaceful and undisturbed life, too.27. Why does the writer think that too much light is a kind of pollution?A. Because there are fewer and fewer stars.B. Because human health has been affected.C. Because too much light is a waste of energy.D. Because some of the wildlife can be harmed.

AYou may not realize it，but you are doing much more than just studying，when you are at school． School is also the place where you learn to get along well with people． But this is not al-ways easy． What can you do if you just don-t like one of your classmates? If you discover that you have problems getting along with your classmates or friends，the most important thing to learn is tolerance(宽容)． Tolerance is the ability(能/J ) to realize and respect(尊重) the differences in others． We can not change the way that other people do，so it is important to learn to live happily with them．Tolerance will make everyone get on better with each other． Getting to know someone may help you understand why they do things differently． Something different does not exactly mean that it is bad． Tolerance teaches us to keep an even temper and open mind ．You need to remember an old saying，"Treat others how you want to be treated"． You would like to be treated kindly by your classmates，so it is important to treat them kindly too．If you tolerate(宽容) something，it does not mean that you have to like it． No one is asking you to change who you are or what you believe in． Tolerance just means that you should respect the differences in others and not try to make them change．It is important to practice tolerance，because it will make everyone's lives easier． Learn to accept(接受) people for their different abilities and interests． The world is very different，and practicing tolerance in your own school and city can help you make a difference．21． What does the writer think of school?At school，students can not only study but also_________________________

In a world where it seems we already have too much to do，and too many things to think about，it seems the last thing we need is something new that we have to learn.But use cases do solve a problem with requirements:with（ ）declarative equirements it's hard to describle steps and sequences of events.Use cases，stated simply，allow description of sequences of events that，taken together，lead to a system doing something useful.As simple as this sounds，this is important.When confronted only with a pile of requiements，it's often（ ）to make sense of what the authors of the requirements really wanted the system to do.In the preceding example，use cases reduce the ambiguity of the requirements by specifying exactly when and under what conditions certain behavior occurs;as such，the sequence of the behaviors can be regarded as a requirement.Use cases are particularly well suited to capture approaches.Although this may sound simple，the fact is that（ ）equirement capture approaches，with their emphasis on declarative requirements and"shall"statements，completely fail to capture the（ ）of the system's behavior.Use cases are a simple yet powerful way to express the behavior of the system in way that all stakeholders can easily understand.But，like anything，use cases come with their own problems，and as useful as they are，they can be（请作答此空）.the result is something that is as bad，if not worse，that the original problem.Therein it's important to utilize use cases effectively without creating a greater problem than the one you started with.A.misapplied

问答题Studies serve for delight, for ornament, and for ability. Their chief use for delight, is in privateness and retiring; for ornament, is in discourse; and for ability, is in the judgement and disposition of business. For expert men can execute, and perhaps judge of particulars, one by one; but the general counsels, and the plots and marshalling of affairs, come best from those that are learned. To spend too much time in studies is sloth; to use them too much for ornament, is affectation; to make judgement wholly by their rules, is the humour of a scholar. They perfect nature, and are perfected by experience: for natural abilities are like natural plants, that need proyning (pruning) by study; and studies themselves do give forth directions too much at large, except they be bounded in by experience. Crafty men contemn studies, simple men admire them, and wise men use them; for they teach not their own use; but that is a wisdom without them, and above them, won by observation.
