Nitrogen helps plants grow. Waste gases from gasburning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground.”可知，與生長(zhǎng)在森林中的樹木相比，城市里的樹木長(zhǎng)得更快是因?yàn)樗鼈儫o需與鄰近的樹木爭(zhēng)奪光照，也能得到更多的氮量，還更容易得到水。故選A。 （2）考查細(xì)節(jié)理解?？梢酝茢啵趸伎梢苑乐沟厍蜃兊貌贿m合居住。 （1）考查推理判斷。Why fastergrowing trees absorb more C02.【答案】 （1）D（2）A（3）A（4）B 【解析】【分析】本文是一篇說明文。Why city living makes trees die young.C.How urban trees can live longer.They can enjoy more shade from neighbors.D.They are more likely to access growth promoters.B.D.To check whether they were healthy.B.To know about their growth rates.It results from the widespread burning of fossil fuels.D.It is one of the side effects of greenhouses.B. tracking, the researchers found city trees absorbed four times as much carbon from the air as forest trees. However, they were twice as likely to die. So over the lifetime of each type of tree, forest trees actually absorbed more CO2.s diameter increases as it grows, just as a person39。 t been much data on whether city trees grow, die and absorb CO2 at the same rate as forest trees do. So some researchers decided to find out. As we all know, the earth would be freezing or burning hot without CO2. However, CO2 is a greenhouse gas, meaning it traps energy from the sun as/heat. That makes temperatures near the ground rise. Human activities, especially the widespread burningof fossil(化石)fuels, have been sending extra greenhouse gases into the air. This has led to a rise in average temperatures across the globe. 6．閱讀理解 故選D。 mouths water?”根據(jù)Smithsonian雜志，世界上大約20%的人容易招蚊子咬。 （4）考查主旨大意?？芍?，文章建議我們可以通過穿淺色衣服來避免蚊子叮咬。 （3）考查細(xì)節(jié)理解。t pregnant.”對(duì)二氧化碳的喜歡使得孕婦很容易被蚊子咬，因?yàn)樗齻儽日Ｏ嗤挲g，相同體型的人呼出多余21%的二氧化碳，可知，孕婦呼出更多的二氧化碳，所以更招蚊子咬。 （2）考查細(xì)節(jié)理解。它們通過聞人和動(dòng)物呼出的二氧化碳來鎖定目標(biāo)；以及第五段中的“Mosquitoes start orienting themselves to carbon dioxide and keep flying upwind as they sense higher concentrations”蚊子開始飛向有二氧化碳的地方，當(dāng)它們感知到高濃度的二氧化碳時(shí)，就保持逆流飛行，可知，蚊子通過感知二氧化碳的增加來鎖定目標(biāo)。 （1）考查細(xì)節(jié)理解。t worry. Some simple tips can help ward them off. Scientists remend that we use insect repellent (驅(qū)蟲劑) 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。 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), people wearing dark colors are more likely to bee targets. t pregnant. t get bitten as much ... as adults, US professor Ted Rosen told Science Alert. Joop van Loon, an entomologist at Wageningen University in the Netherlands, told Live Science, Mosquitoes start orienting (使......朝向) themselves to carbon dioxide and keep flying upwind as they sense higher concentrations (濃度).Mosquitoes are especially active in the late afternoon. While flying along, they use their sense of smell to find possible targets. They find victims (攻擊對(duì)象) by smelling the carbon dioxide (CO2) breathed out by humans and animals.

Millions of antipollution masks were distributed at schools, colleges, hospitals and markets.” 周末期間，由于能見度低，數(shù)百架航班被迫改道、延誤和取消，學(xué)校和辦公室周一關(guān)閉，官員們緊急采取措施，試圖扭轉(zhuǎn)不斷惡化的空氣質(zhì)量。故選B?？芍?，政府盡管發(fā)誓解決這種污染，但情況不僅沒有改變，反而更加嚴(yán)重，使得人們必須佩戴防毒口
