【正文】 o paragraphs? A.Photosynthesis is necessary for the trees to sweat.B.No further experiments will be done other species.C.Other species will be transplanted to North America.D.Groundwater helps the trees survive the extreme heat.【答案】（1）A（2）C（3）D（4）D 【解析】【分析】本文是一篇說明文，聯(lián)合國環(huán)境科學(xué)與林業(yè)學(xué)院的生態(tài)學(xué)家John Drake和他的同事們通過對紅桉樹做實(shí)驗(yàn)，得出結(jié)論：在極度的高溫中，紅桉樹仍然可以通過釋放水分來抵抗熱浪，獲得生存。(1)考查細(xì)節(jié)理解。根據(jù)第一段中的“But at least one species of eucalyptus tree can resist extreme heat by continuing to 39。sweat’”可知，桉樹通過“流汗”，即釋放水分來抵抗極度的熱，故選A。(2)考查細(xì)節(jié)理解。根據(jù)第三段中的“Ecologist John Drake… and his colleagues grew a dozen Parramatta red gum … trees in large, climatecontrolled plastic pods that separated the trees from the surrounding forest for a year in Richmond, Australia.”可知，研究者們將12棵紅桉樹種植在巨大的，氣候受控制的塑料艙里，這種塑料倉將這些樹和周圍的森林分離開來?？芍芯空邆?yōu)檫@些樹創(chuàng)造了一個氣候受控制的生長環(huán)境，故選C。(3)考查詞義猜測。根據(jù)第二段中的“But exceptionally high temperatures are known to greatly reduce photosynthesis”可知，極度的高溫會減少光合作用。由第四段后面的內(nèi)容可知，令研究者們驚訝的是，面對著人工制造出來的熱浪，這些樹繼續(xù)以接近正常的水平蒸發(fā)，有效地使自己和周圍的環(huán)境涼爽下來。結(jié)合這兩點(diǎn)可以推知，面對人工制造出來的熱浪，光合作用應(yīng)該是大大減少，但這并沒有影響樹木的蒸發(fā)。劃線部分意思應(yīng)當(dāng)接近于“大大減少，降低”這一類的意思cease意為“停止”，故選D。(4)考查推理判斷。根據(jù)倒數(shù)第二段中的“The researchers think the Parramatta red gums were able to effectively sweat — even without photosynthesis — because they are particularly good at tapping into water deep in the soil. But if a heat wave and a severe drought （干旱）were to hit at the same time and the groundwater was exhausted, the trees may not be so lucky, Drake says.”可知，這些樹擅長吸取地下水，如果熱浪干旱同時發(fā)生，地下水枯竭的話，那么這些樹生存的可能性就比較小了。由此可以推知，地下水幫助這些樹存活下來。故選D。【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，是一篇科普類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(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。7．閱讀理解 One of the most striking findings of a newly research in the UK is that of the people interviewed, one in two believes that it is being more difficult to meet someone to start a family with. Why are many finding it increasingly difficult to start close relationships? Does modem life really make it harder to fall in love? Or are we making it harder for ourselves? It is certainly the case today that contemporary couples benefit in different ways from relationships. Women no longer rely upon partners for money or status. A man doesn39。t expect his wife to be in (唯一的) charge of running his household and raising his children. But perhaps the knowledge that we can live perfectly well without a partnership means that it takes much more to persuade people to abandon their independence. In theory, finding a partner should be much simpler these days. Only a few generations ago, your choice of soul mate was limited by geography, social convention and family tradition. Although it was never clear，many marriages were essentially arranged. Now those barriers have been broken down. You can approach a builder or a brain surgeon in any bar in any city on any given evening. When the world is your oyster ( 牡蠣), you surely have a better chance of finding a pearl. But it seems that the old conventions have been replaced by the limitations of choice. The expectations of partners are raised to an unmanageable degree: good looks, impressive salary, kind to grandmother, and right socks. There is no room for error in the first impression. We think that a relationship can be perfect. If it isn39。t, it should be ended. We work to protect ourselves against future heartache and don39。t put in the hard emotional labor needed to build a strong relationship. Twelvehour work at the office makes relaxed afterhours dating difficult. The cost of housing and childraising creates pressure to have a stable ine and Career before a life partnership.（1）What is a contemporary family like in UK today?

A man doesn39。t expect his wife to be in sole (唯一的) charge of running his household and raising his children.”可知現(xiàn)在的女子在經(jīng)濟(jì)上獨(dú)立，男子也不能指望女子負(fù)責(zé)所有的家務(wù)和養(yǎng)孩子。說明現(xiàn)在是夫妻雙方共同承擔(dān)負(fù)擔(dān)。故選A。(2)考查細(xì)節(jié)理解。根據(jù)第四段中的“But perhaps the knowledge that we can live perfectly well without a partnership means that it takes much more to persuade people to abandon their independence.”可知，人們認(rèn)為獨(dú)自生活也很好這種觀念使得人們不愿意放棄他們的獨(dú)立生活。故選A。(3)考查細(xì)節(jié)理解。根據(jù)最后一段中的“Twelvehour work at the office makes relaxed afterhours dating(約會) difficult.”可知12小時的工作使得人們約會變得很困難，繁忙的工作花費(fèi)了人們太多的精力。故選B。(4)考查主旨大意。文章主要分析現(xiàn)在的人們?yōu)槭裁春茈y找到生活伴侶，其原因可能主要是對對方的期望過高以及經(jīng)濟(jì)壓力較大的現(xiàn)實(shí)。故選C?！军c(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇社會現(xiàn)象類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，根據(jù)上下文進(jìn)行邏輯推理，概括和歸納，從而選出正確答案。8．閱讀理解 The United States is home to 562 recognized American Indian Nations each with its own language. Yet the number of native. Americans with the ability to speak their tribe39。s language has decreased over the past century. Now, Indian Nations are trying different ways to expand the number of native speakers, and increase interest in their munities to learn tribal languages. Since the late 1800s many American Indian children have at
