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.Putting It All TogetherVery 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.

eg：You will be late if you don’t hurry up .
＝If you don’t hurry up, you will be late .
如果你不快点，你就会迟到的。考向二【易错点】 在含有if引导的条件状语从句的复合句中，如果主句用一般将来时，从句应用一般现在时表将来。
eg：We will go to the farm if you are free this
afternoon .
如果今天下午你有空我们就去农场。典例If it ________, we will go hiking at Cool City Park . A．not rain B．don’t rain
C．won’t rain D．doesn’t rainD【点拨】采用逻辑推理法和分析句子结构法。考查if条件句。句意：如果不下雨，我们将去凉都公园远足。if引导的条件状语从句遵循主将从现的原则，we will go hiking at Cool City Park是主句，那么从句就要用一般现在时表将来。 if条件句，主将从现。 特色土方法考向三在含有if引导的条件状语从句的复合句中，
如果主句是祈使句，从句也要用一般现在时。
eg：Let’s go shopping if you are not busy .
如果你不忙的话，咱们去购物吧。考向四在含有if引导的条件状语从句的复合句中，如果主句含有情态动词，如can, may, must等，从句也要用一般现在时。
eg：You can stay here for the weekend if you like .
如果你愿意，你可以留在这里过周末。拓展(1)if还可以引导宾语从句，意为“是否”。典例We don’t know if our friend ________ . If he ________， we’ll let you know .

B．comes; will come
C．will come; comesC【点拨】采用分析句子结构法。句意：我们不知道我们的朋友是否会来。如果他来了，我们会让你知道。第一个空所在部分是宾语从句，根据句意用一般将来时。第二个空所在部分是if引导的条件状语从句，根据主将从现的原则，用一般现在时。 (2)引导条件状语从句的连词和连词词组还有：
unless(除非)，as/so long as(只要)。
eg：So long as we don’t lose heart, we will find a
way to overcome the difficulty .
