role in attracting mosquitoes. According to Live Science, mosquitoes can lock onto targets from up to 50 meters away. At this distance, what we wear has a huge effect. Due to their vision (視覺(jué)), people wearing dark colors are more likely to bee targets. Being bitten by mosquitoes is annoying, but don39。t worry. Some simple tips can help ward them off. Scientists remend that we use insect repellent (驅(qū)蟲(chóng)劑) and wear lightcolored clothing.(1)How do mosquitoes locate their targets, according to the article? seeking out bright clothes. identifying different blood types. sensing an increase of carbon dioxide. following bigger crowds.(2)Why are pregnant women more likely to be bitten by mosquitoes? larger size helps mosquitoes to see them. breathe out more CO2. are more likely to sweat. body temperatures are higher.(3)How does the article advise you to avoid mosquitoes? regularly. lightcolored clothing. your skin dry and clean. indoors in the evening.(4)What39。s the article mainly about? new finding about mosquitoes. people can avoid mosquito bites. popular myth about mosquitoes. some people are more attractive to mosquitoes than others.【答案】 (1)C(2)B(3)B(4)D 【解析】【分析】本文是一篇說(shuō)明文,介紹了為什么有些人可以整個(gè)夏天坐在戶外乘涼卻不被蚊子叮咬,而有些人一出門(mén)就好像要被蚊子吃掉一樣。 (1)考查細(xì)節(jié)理解。根據(jù)第四段中的“While flying along, they use their sense of smell to find possible targets.

It was obvious that the animal had been struck violently by a ship——but why? Only later, after surveying the whales which lived in the area and measuring the increase of sound pollution from ships did it bee clear that there was a link. The whales had bee desensitised to the noise of approaching boats and were being struck by them, often seriously. We never thought that this could be something that could kill, recalls (回憶) Andre, who is the director of the Laboratory of Applied Bioacoustics at the Technical University of Catalonia, Barcelona. Andre has spent 20 years developing an advanced system to better understand why incidents like this happen. His underwater microphones have exposed a world of deafening sound and animal munication never observed with such clarity(清晰) before. It was not an easy task. Sound waves don39。t travel through water in the uniform, predictable way they do through the air. Instead, the temperature, salinity (鹽度) and, flow of water have great effects on their path. What can be done? One solution is to change shipping routes to courses where ships are statistically less likely to meet animals. It39。s also possible to slow ships down to 18km/h or less, which is less likely to seriously injure a whale. As for dealing with the root cause of the problem, the UN39。s International Maritime Organisation has already published guidelines on how to quieten ships, but it will be a while before the effects of such changes might be observed. The ocean is not our world, ments Andre. But it is ours to look after. And thanks to his work, we can better understand the effects of subsea sound pollution.(1)What does the underlined word desensitised in Paragraph 2 mean? A.Stubborn.B.Flexible.C.Dull.D.Friendly.(2)What39。s one way to solve the problem according to the text? A.To lower the speed of ships.B.To reduce the number of ships.C.To set up preserves under the sea.D.To give the injured animals timely treatment.(3)What is the author39。s attitude towards what Michel Andre has done? A.Doubtful.B.Disapproving.C.Positive.D.Uncaring.(4)What is the text mainly about? A.A great expert.B.Noise in the sea.C.Animals in the sea.D.Sea exploration technology.【答案】 (1)C(2)A(3)C(4)B 【解析】【分析】本文是一篇說(shuō)明文,
