英语的语态分为主动语态和被动语态，主要由动词的变化形式来体现。英语中有些不及物动词或不及物动词词组，汉语理解往往是及物的，而不及物动词却有汉语中及物动词的意思，所以同学们在平时的英语学习中要特别注意这一点。
「信息提示」
比较下面两幅图片。请以“Great Changes in Our Country”为题写一篇短文，介绍改革开放20多年来祖国的巨大的变化。词数80左右。
提示词：overpass 天桥
「习作实况」
Great Changes in Our Country Great changes have been (1) taken place in our country. Many buildings have been builded (2) in cities and towns， even at villages. The more cars we have， the more crowded the roads are. So the roads were become (3) wider and wider. Many overpasses have been builded (4) in big cities. Chinese people‘s life is better now. We can buy things that we need in every part of the country. We have TVs， washing machines， fridges， computers，cars，etc. These things couldn’t buy (5) twenty years ago. We‘ll study harder and make our country stronger and more beautiful.
「精讲点拨」
(1)take place是不及物动词短语，没有被动语态。
(2)、(4) 被动语态的过去分词用得不对。
(3)动词become在这里是系动词，后接形容词比较级作表语。系动词通常没有被动语态。
(5)此处应用被动式couldn‘t be bought.
