(4)It+ takes(sb.)+时间/金钱+do do sth.意为”做某事花费了某人多少时间/金钱” Eg:It took him three hours to finish the work. 2.it做形式宾语，基本句型是：主语+v.+it+宾语补足语+真正的宾语 （1）it代替不定式做形式宾语时，常与consider, think, make, find, believe, count, feel, imagine, prove,take等动词连用。 Eg:I find it not so difficult to learn a forein language.我发现学一门外语并不那么困难 （2）it也可以代替动名词（短语）和宾语从句作形式宾语。 Eg:We think it useless learning theory without practice. 学理论不实践是无用的 五、书面表达： 地球是人类赖以生存的家园，干净的环境是我们共同的向往，保护环境人人有责。请根据提示与要求，结合自己的生活实际，以“What can we do for our environment?”为题写一篇短文，说说怎样才能保护好环境。 提示：① 节约能源：比如随手关灯，使用纸的两面，可以重复使用旧课本（textbook）；② 减少污染：比如购物时使用布袋，步行或骑车去上学。 What can we do for our environment? We all live on the same planet. It is our duty to protect the environment. But what can we do? In daily life, we can use cloth bags instead of plastic ones when we go shopping. We should never forget to turn off the lights when we leave the room. It will save much electricity. At school, we should use both sides of the paper. To save more paper, we can reuse the old textbooks. What’s more, we should try our best to reduce pollution. For example, we can walk or ride bikes to school instead of going by car. In a word, we should try our best to protect the environment. 本文来源：https://www.wddqw.com/doc/bf6f0cd1730abb68a98271fe910ef12d2af9a9ca.html
