Can plants eat people? Probably not，but there are many plants that eat meat．Some of them are big．And they can eat small animals．One famous meat-eating plant is the Venus flytrap(捕蝇草)．

The 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．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．Slowly，the plant eats the fly．

Why do plants do it? 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 some of the bigger plants don’t get the same idea !

阅读下面的文字，完成下面的题。

　　扬州的旧巷大多是这样，七拐八绕，枝枝蔓蔓，曲径通幽，八卦阵似的。安乐巷也不例外，两旁青砖高墙，中间青石铺路。这是安乐巷27号门牌，坐西朝东，极普通的那种民居，如果不是挂着江 * * * * 题写的“朱自清故居”五字，你若是骑车穿巷，脚下稍一用力，便会倏忽而过。

　　故居就和他的主人一样，很不引人注目。站在故居门前，我不由得想起了郭良夫先生在编选的《完美的人格》里的一个细节，朱先生在清华大学任文学院中文系主任时，总是喜欢穿平底布鞋，每逢开会，从不坐 * * 台，只拣一个不起眼的角落，静听同事们阔论。朱先生在会场上偏于一隅，同他在这巷子里偏于一隅的故居是多么的一脉相承啊。于是，我头脑中闪出本文的题目——《穿布鞋的故居》。如今，到处在修茸或重建名人故居，画廊漆柱，巨匾敞庭，又气派又热闹。尤其在时髦文艺搭台经济唱戏的今天，名人故居拥有了一份独特的召唤力。而朱先生的故居没有这份辉煌，为了供后学瞻仰，有关部门只是将原先居住在这里的市民迁了出去，腾空房间便成了。

　　故居很小，小得只有几间木结构的房子，小得你站在门庭下清咳一声，每个角落里都能听到。这又和朱先生的为人如出一辙：绝不故作高深，只求平易近人。于是我这样概括这座小院落：巷子很深，故居却很浅。游人很少，有时整天卖不出一张门票。扬州有座瘦西湖，到过瘦西湖的外地人，回去之后会向别人炫耀一番，我到过瘦西湖，而朱自清故居不会有这样的反应。首先没有殷殷期盼拜访的人，绝不会有一种陈年老窖般的期待，因为他根本就没有想过要去；而到过的人更不会将此作为话题，因为我相信，能够在今日仍念念不忘这片陋房的人正是感染了朱先生的平淡与平和的。为此我反复为故居的车马无声而庆幸，这也许正是先生的本意。

1．第4段中说“巷子很深，故居却很浅”，这句话有什么深刻含义？用自己的话回答。（不超过20字）

_________________________________________________

2．文章最后说“这也许正是先生的本意”，根据上文，指出“本意”的具体含义。（不超过20字）

_________________________________________________

3．第3段中说，名人故居“拥有一份独特的召唤力”。而朱先生的故居“没有这份辉煌”，对此，简要谈谈你的理解。

4．文章为什么要以“穿布鞋的故居”为题？试简要回答。
