Question

8．We talk every day．When we have good news，we like to share it with our good friends and when something terrible happens，we make it known to others soon．But can you imagine that a tree can talk and share hews too？Of course，no tree moves lips and says words just as people do．Strange as it may sound，though，some trees do manage to communicate with each other．
Willow（柳樹） trees are the best-known of these trees．When insects（昆蟲） begin nibbling（叮咬） a willow tree，the tree sends out a special smell at once．This smell tells the other willows that harmful insects are coming near．All of them quickly make a chemical（化學(xué)物質(zhì)） in their leaves．This chemical is bad to the insects．The insects do not like it and they fly away soon．In this way，the willow trees protect themselves from the insects．
The next time when you take a walk in the woods，maybe the trees are"talking"to each other quietly．And when someone says that trees cannot"talk"，please tell them that even trees give messages to each other，too．

Answer 1

分析 短文講了樹可以通過(guò)發(fā)送一種氣味來(lái)進(jìn)行相互之間的信息交流，有昆蟲叮咬它們時(shí)，它們也會(huì)發(fā)出化學(xué)物質(zhì)來(lái)保護(hù)自己．

解答 答案：49．C   細(xì)節(jié)理解題．根據(jù)第二段第一行句子When insects begin nibbling （叮咬） a willow tree，the tree sends out a special smell at once．This smell tells the other willows that harmful insects are coming near．當(dāng)昆蟲開始叮咬一棵柳樹的時(shí)候，樹立刻發(fā)出一種特殊的氣味．這氣味告訴其它的柳樹，有害昆蟲在附近．可知柳樹用氣味發(fā)送信息．故選C．      
50．B  詞義猜測(cè)題．根據(jù)上下句But can you imagine that a tree can talk and share hews too？Of course，no tree moves lips and says words just as people do．Strange as it may sound，though，some trees do manage to communicate with each other．但你能想象一棵樹可以交流和分享信息嗎？當(dāng)然，樹沒(méi)有挪動(dòng)…，像人一樣說(shuō)話．聽起來(lái)很怪，不過(guò)，有些樹能互相交流．可知由下文人類用嘴說(shuō)話，所以上文應(yīng)是樹木沒(méi)有挪動(dòng)嘴唇，而像人一樣，因此lips應(yīng)是嘴唇的意思．故選B．
51．C   細(xì)節(jié)理解題．根據(jù)第一段第二行句子some trees do manage to communicate with each other．有些樹能互相交流．可知文章告訴我們樹能夠相互交流．故選C．
52．d-a-b-c   細(xì)節(jié)排序題．根據(jù)第二段內(nèi)容及其句子When insects（昆蟲） begin nibbling（叮咬） a willow tree，the tree sends out a special smell at once．當(dāng)昆蟲開始叮咬一棵柳樹的時(shí)候，樹立刻發(fā)出一種特殊的氣味．All of them quickly make a chemical（化學(xué)物質(zhì)） in their leaves．This chemical is bad to the insects．The insects do not like it and they fly away soon．它們很快就在葉子上制造了化學(xué)物質(zhì)，這種化學(xué)物質(zhì)對(duì)昆蟲有害，昆蟲不喜歡它們，它們很快就飛走了．可知正確的順序應(yīng)是d-a-b-c．故答案為d-a-b-c．
