Once this is done, you look at the new words and new senses and draft a definition.（我們根據(jù)一個(gè)單詞在記載的上下文中如何使用來定義它，決定這個(gè)用法是否已經(jīng)被我們的字典所涵蓋。故選D。這些記錄被添加到數(shù)據(jù)庫(kù)中，它們是我們編寫定義時(shí)使用的原材料。re looking for are words that catch our eye.

In a recent interview, Sokolowski and Stamper talked about their job and what the way we use words says about us collectively.7．閱讀理解 故選B。因此一些研究人員決定弄清楚”；文章第四段再次介紹了他們的研究發(fā)現(xiàn)：城市里的樹木比森林中的樹木長(zhǎng)得更快，但死得更早；文章最后一段介紹了城市里的樹木比森林中的樹木生長(zhǎng)得更快的幾個(gè)原因。 （4）考查推理判斷。由此可以推斷，城市里的樹木比森林中的樹木更可能獲得生長(zhǎng)促進(jìn)劑。根據(jù)最后一段中的“Street trees also benefit from higher levels of nitrogen (氮）in rainwater. 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?，二氧化碳可以防止地球變得不適合居住。 （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A。s gone.”是其現(xiàn)狀。第一段和第二段說明了the Buffalo River嚴(yán)重受污染的情況，第三、四段介紹了為改變污染狀況所做的努力，以及最后一段中的“So far，the Buffalo River39。故選A。；以及最后一段中的“So far，the Buffalo River39。 （3）考查推理判斷。s Water Conservationist of the Yearaward.
