8、be used by other plants,insects,and animals.But they didnt know exactly how important the insects were in keeping the forest healthy and functional,so they removed termites from a particular spot in the forest and saw how it responded. As luck would have it.Hannah Griffiths and her colleagues starte

9、d their experiment when the forest was hit by an extreme drought(干旱).During the non-drought years,they saw there wasnt much difference between the normal plots and the ones where theyd removed the termites.But during the drought,the effects were marked.What they found was unexpected:in the termite-r

10、ich areas,the soil stayed slightly wet,more tree seedlings sprouted(抽芽),and the system was full of activity despite the long,hard dry spell.

15、的主要原因之一。后果:海平面上升;自然灾害频繁。措施:1.多使用清洁能源,少用煤、油; 2.在可能的情况下以步代车; 3.注意:1.词数80个左右; 2.可以适当增加细节,以使行文连贯。一、根据语境及汉语提示写出单词1.highlighted。句意:去年柯林斯写了一首感人的诗,突出了无家可归者的处境。2.cruelty。句意:英国有禁止虐待动物的法律。3.presentation。句意:我的陈述应该能阐明你们可能有的任何问题。4.establish。句意:我们希望与贵公司建立业务关系。5.sustainable。句意:建立一个高效和可持续的交通系统是很重要的。6.reduces。句意:这种药降

18、在热带雨林中,白蚁啃食落叶和枯木,控制掉落的物质,并让枯木中的营养物质重新回到生态系统中,供其他植物、昆虫和动物使用。所以关于白蚁,科学家们了解到它们为它们所生活的生态系统做出了很大的贡献。故B选项正确。3.C。推理判断题。由第四段最后两句“但在干旱期间,这些影响是很显著的。他们的发现出乎意料:在白蚁多的地区,土壤仍保持轻微的湿润,更多的树苗发芽,尽管经历了漫长而艰苦的干旱期,周围的生态系统仍然充满活力。”可推知,白蚁帮助雨林在气候变化时得以生存。故C选项正确。4.B。段落大意题。由最后一段内容(她指出,对格里菲斯来说,只是因为他们碰巧研究了干旱,他们才能够发现白蚁对生态系统的真正重要性。“这

19、在我脑海中敲响了警钟,”她说,“因为它让我想,我们还不知道什么?如果我们开始破坏生物群落,我们不知道会发生什么。)所以判断出格里菲斯在最后一段告诉我们,在破坏一个物种之前,我们应该三思而后行。故B选项正确。四、书面表达With the development of economy,more and more greenhouse gases are being discharged into the air.Carbon dioxide makes up about 60% of the greenhouse gases,which is considered to be one of the

20、 greatest causes of global warming.It has harmful effects,causing the sea level to rise and many natural disasters to strike.So we must take effective measures to save our planet.First,we should use more clean energy and less coal and oil.Second,we should go to work on foot or by bus instead of driving a car if possible.Third, we should plant more trees, because plants can turn Carbon dioxide into oxygen.More importantly, we should form the habit of saving energy in our daily life.We hope that all these measures will be effective and bring back a healthier environment.第10页（共10页）
