【正文】 Now scientists say it is a race against time to explore these new ecosystems before they are transformed to the light. Marine biologist Dr Katrin Linse from the BAS is leading the mission. Professor David Vaughan, science director at the BAs, said, We need to be bold (大膽的) on this one. Larsen C is a long way south and there39。 There is growing concern about the possible impact of climate change in the Antarctic. Earlier this month, a report revealed that melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of the sea level rise. The research, published by the National Academies of Science, Engineering and Medicine, said, At the current rate, the world39。To study how the iceberg was formed.B.To explore a new way to prevent climate change.D.The Larsen C ice shelf.B.The A68 iceberg with the ecosystem beneath it.D.It is as big as London.B.It will disappear in a very short time.D.There is no need to worry about climate change in Antarctica.B.Many creatures living in deep water will die out due to climate change.D.冰山下面顯現(xiàn)的新的海洋生態(tài)系統(tǒng)為科學(xué)家提供了研究未知的海洋生物的機(jī)會。根據(jù)第二段中的“Now scientists say it is a race against time to explore these new ecosystems before they are transformed to the light.”可知，科學(xué)家著急趕去世界最大的冰山是為了在其受到光照影響之前研究這座冰山下面的海洋生態(tài)系統(tǒng)。 （2）考查詞義猜測。故選C。根據(jù)第一段中的“to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf.”到達(dá)一個新發(fā)現(xiàn)的在拉森冰架下面隱藏了12萬年的的生態(tài)系統(tǒng)，可知選D。根據(jù)最后一段中的“…At the current rate, the world39。 【點(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測和推理判斷三個題型的考查，是一篇環(huán)境類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，同時根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，從而選出正確答案。 While faking and fierce looks are among animals great defenses, many species know that everyone runs from a big stink (臭氣) too. Vultures, are street sweepers that feast on the rotting flesh of dead animals, which benefits us by ridding our highways and landscapes of animal bodies and the bacteria they might carry. When vultures feel threatened they vomit, and the smell of vomitedon dead bodies puts of most predators. Throwing up allows the vulture to fly away more quicklyand the vomit can hurt the aggressor39。 Opossum (負(fù)鼠)t have to fax anyone a death certificate. They just lie there with their tongues hanging out with the smell of dead flesh, sometimes for hours, effectively convincing potential predators they can find a much fresher meal elsewhere. Even if they keep getting attacked, they won39。 Hoatzin (磨雉)s the only bird known to digest by fermentation, like a cow. This process is what causes its smell and has earned it the nickname the stink bird Millipedes are tricky. For starters they look wormy. Their name is deceptive, too: Their legs number about 750. Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers. The graceful sea hare is plain in taste in the first place, so it39。 Researchers using lobsters (2f) as model predators found that the sea blocks the lobsters receptive mechanism. In other words, the sea hare gives its attacker the equivalent of a stuffy nose so they don39。being plain in taste at the discovery of a predatorB.releasing substance to make predators unable to smell itD.The vulture carries bacteria so that predators dare not get close to it.B.The hoatzin eats cow shit so that it is nicknamed as stink bird.D.vultureopossummillipedesea hare【答案】 （1）C（2）B（3）C 【解析】【分析】本文是一篇說明文，介紹了一些野生動物是如何進(jìn)行自身防御的。根據(jù)故選C。根據(jù)t have to fax anyone a death certificate.

But they acknowledged that things were different for graduates today, who leave university with huge debts and fewer job opportunities. However, the study says, daytoday tensions about the prospects of achieving different dimensions of independence, which in a few extreme cases came close to conflict, characterised the experience of a majority of parents and a little over half the graduates.Boomerang children made their parents happier.B.s return.C. quality of life became worse than before.D.causeB.ariseD.They are ashamed of turning to their parents for help.B.They are doubtful about whether they should return.D.The children want to keep in closer touch with their parents.B.It is harder for the children to secure a satisfying job.D.Both parents and children enjoy a more harmonious relationship.B.Not only parents but also children want to be independent.D.而這一發(fā)現(xiàn)與今年早些時候發(fā)表的一項(xiàng)研究結(jié)果相矛盾，該研究顯示，返鄉(xiāng)的成年子女會導(dǎo)致父母的生活質(zhì)量和幸福感顯著下降。 （1）考查推理判斷。 quality of life and wellbeing.”這一發(fā)現(xiàn)與今年早些時候發(fā)表的一項(xiàng)研究結(jié)果不一致，早些的研究顯示，返鄉(xiāng)的成年子女會導(dǎo)致父母的生活質(zhì)量和幸福感顯著惡化。 （2）考查詞義猜測。 quality of life and wellbeing. ”通過新舊研究對比，以往的研究表明，返鄉(xiāng)的成年子女會導(dǎo)致父母的生活質(zhì)量和幸福感顯著下降。故選A。根據(jù)第三段中的“The young adults taking part in the study were‘more positive than might have been expected’about moving back home – the shame is reduced as so many of their friends are in the same position, and they acknowledged the benefits of their par
