11、光也可带来抑郁症，这项研究至少在动物身上得到了验证。1D细节理解题。根据“Compared with mice exposed to normal nighttime darkness，those getting dim light at night lost their strong preference for sweet drinks”可知，那些在夜晚持续接受暗淡灯光的老鼠失去了对于甜饮料的浓厚喜好，即没有那么喜欢甜饮料了，故选D项。2C词义猜测题。通过原文quash前面also可以断定，quash的意思等于前面一句话的意思，即症状消失了，故选ease“缓解，减轻”。3A推理判断题。根据
12、最后一句可知，灯光可以影响生物钟，生物钟的改变可以影响行为，故选择A项。4A主旨大意题。根据文章首段“Doctors sometimes prescribe light therapy to treat a form of depression in people who get too little morning sun.But too much light at other time may actually cause such mood disorders.”可知，本文主要讨论nighttime light与mood disorder或depression的关系，故A项正确。阅读下列

23、antic Ocean. The canal served as a route over which industrial goods could flow into the west, and materials could pour into the east. The Erie Canal helped New York develop into the nations largest city. The building of the canal was paid for entirely by the state of New York. It cost $ 7,143,789,
24、but it soon gained its price many times over. Between 1825, when the canal was opened, and 1882, when toll charges(过运河费) were stopped, the state collected $121,461,891. For a hundred years before the Erie was built, people had been talking about a canal which could join the Great Lakes and the Atlan
25、tic Ocean. The man who planned the Erie Canal and carried the plan through was De Witt Clinton. Those who were against the canal laughingly called it “Clintons Ditch(沟)”. Clinton talked and wrote about the canal and drew up plans for it. He and Governor Morris went to Washington in 1812 to ask for h

31、 torn off, the lid opened and the paper removed, the chocolate itself then has to be unwrapped from its own piece of paper. But this overuse of wrapping is not limited to luxuries. It is now becoming increasingly difficult to buy anything that is not done up in beautiful wrapping.The package itself
32、is of no interest to the shopper, who usually throws it away immediately. Useless wrapping accounts for much of the refuse put out by the average London house-hold each week. So why is it done? Some of it, like the cellophane on meat, is necessary, but most of the rest is simply competitive selling.
33、 This is absurd. Packaging is using up valuable energy and resources and polluting the environment.Recycling is already happening with milk bottles which are returned to the dairies (牛奶场）, washed out, and refilled. But both glass and paper are being threatened by the growing use of plastic. More dai
34、ries are experimenting with plastic bottles.The trouble with plastic is that it does not rot. Some environmentalists argue that the only solution to the problem of ever increasing plastic containers is to throw away plastic altogether in the shops, a suggestion unacceptable to many producers who say
35、 there is no alternative (替代品) to their handy plastic packs.It is evident that more research is needed into the recovery and re-use of various materials and into the cost of collecting and recycling containers rather than producing new ones. Unnecessary packaging, intended to be used just once, and
36、to make things look better so more people will buy them, is clearly becoming increasingly absurd. But it is not so much a question of throwing away packaging as using it wisely. What is needed now is a more advanced approach to using scarce resources for what is, after all, a relatively unimportant
