句子类型
类别 构成 例句
简单句 The Simple Sentence 由一个主语（或并列主语）和一个谓语（或并列谓语）构成的句子。 I get up at six in the morning.
My mother and I often go shopping.
Some students walk or ride bikes to school.
复合句 The Complex Sentence 由一个主句和一个或多个从句构成的句子。 What do you want to be when you grow up

状语从句（Adverbial Clause） 是指句子用作状语时，起副词作用的句子。 状语从句根据其作用可分为时间、地点、原因、条件、目的、结果等从句。状语从句一般由连词(从属连词)引导，也可以由词组引起。
※ While John was watching TV, his wife was cooking.（时间状语从句）
当约翰看电视时，他的妻子正在做饭。
※ He didn’t attend classes yesterday because he was ill.（原因状语从句）
他病了，所以他昨天没有来上课。
※ He got up so early that he caught the first bus. （目的状语从句）
他很早起床以便赶上第一班公共汽车。
※ We’ll start our project if the president agrees. （条件状语从句）
如果总统同意，我们将开始我们的项目。
if引导的条件状语从句
if作从属连词，意为“如果”，用来引导条件状语从句，表示主句动作发生的条件。if引导的条件状语从句可放在主句之前，也可放在主句之后。但当if引导的条件状语从句放在主句之前时，常用逗号与主句隔开。
1.主句为以下情况之一时，条件状语从句用一般现在时：
①主句是一般将来时。
※ If it doesn’t rain tomorrow, we will go to the zoo.
②主句谓语部分含有情态动词（may, might, can, must, should等）。
※ If you eat bad food, you may fall ill.
③主句为祈使句。
※ If the light is red, wait for a minute.
2.有些句子可与含if条件状语句互相转换。
①祈使句+ and / or +陈述句。
※ Hurry up, or you’ll miss the train.
= If you don’t hurry up, you’ll miss the train.
※ You will be healthier if you eat well.
= Eat well and you will be healthier.
②借助with或without。
※ You can’t drive the car with the door open.
= You can’t drive the car if the door is open.
※ If there is no water, fish will die.
= Fish will die without water.

Computers Are Useful Tools
Computers are fast and seldom make mistakes. They can do many everyday jobs quickly and easily. They are widely used in factories, hospitals and banks.
　People, such as scientists, writers, teachers and students, use computers to do all kinds of work. But years ago, computers couldn’t do what they do today. They were very big and expensive.
Very few people were interested in them or knew how to use them. Today’s computers are smaller, cheaper and much easier to use. People use them at home, at work and even when they travel.
　Computers and the Internet have changed the way we communicate and allow us to connect in ways we didn’t think were possible in the past.

2. Only factories, hospitals and banks use computers. (　　)
