Question

5．Can plants eat people？Probably not，but there are many plants that eat meat．Some of them are big．And thay can eat small animals．One famous meat-eating plant is Venus Flytrap（捕蠅草）．Venus flytrap is a very strange plant．It grows in dry parts of the United States．Its leaves are like the pages of a book．They can open and close very quickly．Inside the leaves，there are three small hairs．If a fly touches one of the hairs，the leaf closes quickly，so the fly cannot get out．In about half an hour，the leaf presses the fly until it is dead．Then，the plant covers the fly and slowly eats it．Why do plants do that？Most plants get what they need from the sun，the air，and the ground．In some places，the ground is very poor．It doesn't have all these important things，especially nitrogen （氮）．Animal meat has a lot of nitrogen，so some plants eat meat to get what they need．Let's hope that bigger plants don't get the same idea!

Answer 1

分析 全文大意：
短文講了世界上有很多植物能夠捕食動(dòng)物，并重點(diǎn)介紹了生長(zhǎng)在美國(guó)干旱地區(qū)的一種食肉植物捕蠅草．它的葉子像書的頁(yè)面，能很快的開合．在葉子里面有三根小觸毛．如果蒼蠅碰到其中一根，葉子會(huì)很快合上．蒼蠅就出不去了，約半小時(shí)的時(shí)間葉子就能把蒼蠅擠壓致死．然后被慢慢吃掉．為什么植物會(huì)這樣做呢？大部分植物會(huì)在陽(yáng)光、空氣、土壤中得到他們所需的養(yǎng)料．在一些地方，土壤貧瘠．并沒有這些物質(zhì)，尤其是氮．動(dòng)物的肉類中含有大量的氮．所以一些植物吃肉是為了從動(dòng)物的肉中獲得需要的養(yǎng)分．讓我們希望更大的植物不會(huì)有同樣的想法．

解答 答案：
56：A       細(xì)節(jié)理解題    根據(jù)第四句One famous meat-eating plant is the Venus flytrap（捕蠅草）．可知Venus flytrap（捕蠅草）是一種植物．故選A．
57：C       細(xì)節(jié)理解題    根據(jù)第六句It grows in dry parts of the United States．可知捕蠅草生長(zhǎng)在美國(guó)干旱地區(qū)，故選C．
58：D       細(xì)節(jié)理解題     根據(jù)第二句和第三句there are many plants that eat meat．Some of them are big，and they can eat small animals．可知其中一些植物能吃小動(dòng)物，故選D．
59：A       詞義猜測(cè)題     根據(jù)第十句If a fly touches one of the hairs，the leaf closes quickly，so the fly cannot get out．如果蒼蠅碰到其中一根，葉子會(huì)很快合上．蒼蠅就出不去了，可知兩片葉子快速合上，應(yīng)是擠壓之力，故選A．
60：C       細(xì)節(jié)理解題     根據(jù)短文倒數(shù)第二句Animal meat has a lot of nitrogen，so some plants eat meat to get what they need描述可知指物是想從動(dòng)物的肉中獲得需要的養(yǎng)分，故選C．

點(diǎn)評(píng) 這是一篇知識(shí)性很強(qiáng)的短文，重點(diǎn)講了捕蠅草捕食過程，在短文最后分析了這些植物捕食動(dòng)物的原因．內(nèi)容條理清楚，淺顯易懂．每個(gè)小題都能輕松地從文中找到適當(dāng)根據(jù)，答題中帶著問題細(xì)心閱讀即可．
