Now, Indian Nations are trying different ways to expand the number of native speakers, and increase interest in their munities to learn tribal languages.Yet the number of native. Americans with the ability to speak their tribe39。 8.閱讀理解 故選C。(4)考查主旨大意。根據最后一段中的“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,繁忙的工作花費了人們太多的精力。故選A。(2)考查細節(jié)理解。說明現(xiàn)在是夫妻雙方共同承擔負擔。根據第三段中的“Women no longer rely upon partners for economic security or status.

We work to protect ourselves against future heartache and don39。 But it seems that the old conventions have been replaced by the limitations of choice.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. 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. 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。7.閱讀理解故選D。根據倒數(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。劃線部分意思應當接近于“大大減少,降低”這一類的意思cease意為“停止”,故選D。由第四段后面的內容可知,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。(3)考查詞義猜測。根據第三段中的“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。sweat’”可知,桉樹通過“流汗”,即釋放水分來抵抗極度的熱,故選A。(1)考查細節(jié)理解。D.No further experiments will be done other species.C.Photosynthesis is necessary for the trees to sweat.D.C.B. conditions in their natural environment.(3)The underlined phrase “ground to a near halt” in Paragraph 4 means “________”.

The trees grown in warmer conditions coped just as well as the others, and photosynthesis rates bounced back to normal after the heat wave passed, Drake and his colleagues reported online in Global Change Biology. Ecologist John Drake of the . College of Environmental Science and Forestry and his colleagues grew a dozen Parramatta red gum (Eucalyptus parramattensis) trees in large, climatecontrolled plastic pods that separated the trees from the surrounding forest for a year in Richmond, Australia. Six of the trees were grown at surrounding air temperatures and six at temperatures three degrees Celsius higher. The researchers withheld (扣留) water from the surface soil of all 12 trees for a month to imitate a mild dry spell, then induced a fourday “extreme” heat wave: They raised the maximum temperatures in half of the pods(three with surrounding temperatures and three of the warmer ones)— to 44 degrees ℃. As plants change sunlight into food, or photosynthesize (光合作用), they absorb carbon dioxide through pores on their leaves. These pores also release water via transpiration(蒸騰), which circulates nutrients through the plant and helps cool it by evaporation(蒸發(fā)). But exceptionally high temperatures are known to greatly reduce photosynthesis—and most existing plant models suggest this should also decrease transpiration, leaving trees in danger of fatally overheating. Because it is difficult for scientists to control and vary trees39。6.閱讀理解”這名教授說得這些話暗含的意思是醫(yī)務人員應該尊敬生命和人道,故選D。re a doctor, the trick is to have a person and not turn them into a dead body,’ and he laughed, shook my hand and walked away.”可知教授說得這段話的意思是:“在你剛開始訓練解剖尸體的時候,你要設法把尸體變成一個人。(4)考查推理判斷。(3)考查細節(jié)理解。根據第三段中的“‘Me and Mrs. Jones, we39。根據第二段中的“It might seem rather negligent not to know the basic facts of my patient ,but I had a valid reason—Mrs. Jones was dead, and had been dead for about three years before I made a patient of her.”可知瓊斯夫人在去世后,把遺體捐給了醫(yī)學院,所以在她去世之前,作者并不認識她,故選C。Medical staff ought to have respect for life and humanity.【答案】(1)C(2)B(3)A(4)D 【解析】【分析】本文是一篇記敘文,作者講述了和瓊斯夫人之間的故事,說明了醫(yī)務人員應該尊敬生命和人道。Being a doctor has nothing to do with the medical training.C.Guilty.(4)What did the professor imply by his words in the last paragraph?
