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（捕蝇草）．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：
短文讲了世界上有很多植物能够捕食动物，并重点介绍了生长在美国干旱地区的一种食肉植物捕蝇草．它的叶子像书的页面，能很快的开合．在叶子里面有三根小触毛．如果苍蝇碰到其中一根，叶子会很快合上．苍蝇就出不去了，约半小时的时间叶子就能把苍蝇挤压致死．然后被慢慢吃掉．为什么植物会这样做呢？大部分植物会在阳光、空气、土壤中得到他们所需的养料．在一些地方，土壤贫瘠．并没有这些物质，尤其是氮．动物的肉类中含有大量的氮．所以一些植物吃肉是为了从动物的肉中获得需要的养分．让我们希望更大的植物不会有同样的想法．

解答 答案：
56：A       细节理解题    根据第四句One famous meat-eating plant is the Venus flytrap（捕蝇草）．可知Venus flytrap（捕蝇草）是一种植物．故选A．
57：C       细节理解题    根据第六句It grows in dry parts of the United States．可知捕蝇草生长在美国干旱地区，故选C．
58：D       细节理解题     根据第二句和第三句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动物，故选D．
59：A       词义猜测题     根据第十句If a fly touches one of the hairs，the leaf closes quickly，so the fly cannot get out．如果苍蝇碰到其中一根，叶子会很快合上．苍蝇就出不去了，可知两片叶子快速合上，应是挤压之力，故选A．
60：C       细节理解题     根据短文倒数第二句Animal meat has a lot of nitrogen，so some plants eat meat to get what they need描述可知指物是想从动物的肉中获得需要的养分，故选C．

点评 这是一篇知识性很强的短文，重点讲了捕蝇草捕食过程，在短文最后分析了这些植物捕食动物的原因．内容条理清楚，浅显易懂．每个小题都能轻松地从文中找到适当根据，答题中带着问题细心阅读即可．
