四年级上册现代文阅读专题(二)11.阅读:战国时期,魏国的国君派西门豹去管理漳河边上的邺县。
西门豹到了那个地方,看到田地荒芜,人烟稀少,就找了位老大爷来,问他是怎么回事。
老大爷说:“哪家有年轻的女孩,巫婆就带着人到哪家去选。
有钱的人家花点儿钱就过去了,没钱的只好眼睁睁地看着女孩被他们拉走。
到了河神娶媳妇那天,他们在漳河边放一条苇席,把女孩打扮好了,让她坐在苇席上,顺着水漂去。
苇席先还是浮着的,到了河中心就连女孩一起沉下去了。
有女孩的人家差不多都逃到外地去了,所以人口越来越少,这地方也越来越穷。
”西门豹问:“那么漳河发过大水没有呢?”老大爷说:“没有发过。
倒是夏天雨水少,年年干旱。
”西门豹说:“这样说来,河神还真灵啊。
下一回他娶媳妇,请告诉我一声,我也去送送新娘。
”(1)照样子,写词语。
例:眼睁睁(ABB式)(2)读句子完成练习。
西门豹到了那个地方,看到田地荒芜,人烟稀少,就找了位老大爷来,问他是怎么回事。

西门豹说:“这样说来,河神还真灵啊。
下一回他娶媳妇,请告诉我一声,我也去送送新娘。
”①西门豹真的相信给河神娶媳妇可以免除灾害。
②西门豹说的是反话,他准备破除迷信。
(4)邺县这个地方为什么会越来越穷?12.课外阅读。
螳螂法布尔螳螂的外表很美丽。
它长着细长的腰身,还披着一件淡绿色的外衣。
当它把上半身直立起来的时候,前腿也会前伸,就像正在祈祷一样,模样很像一个虔诚的修女。
螳螂虽然很美丽,但性情却非常凶猛。
它那像镰刀一样的大腿是一对捕捉足,腿上有很多钩刺和锯齿。
它的小腿上也有很多锯齿,甚至比大腿上的还要多。
小腿锯齿的末端长着尖锐的硬钩子。
记得有一次,我试图抓住一只螳螂。
我一碰到它,就被它的刺牢牢“抓”住了。
螳螂静止的时候,看起来很温和。
只要别的昆虫在它面前路过,是有意还是无意的,它就会立刻把翅膀伸展开,用大腿迅速地把路过此地的昆虫抓住。
