新版上海牛津版七年级上册unit6知识点及语法

一．条件状语从句的概念

条件状语从句，表示主句动作发生的条件。即在某种条件下，一件事情可能发生。

在英语中由连接词if或unless等引导的状语从句叫做条件状语从句。条件是指某一件事情实现之后（状语从句中），一件事情（主句）才能发生，通常译作“假如，只要，如果”

等意思。条件状语从句中，主从句的时态要遵循“主将从现”的原则。即，主句是将来时态时，从句用一般现在时代替将来时态。

二.条件状语从句的引导词

1.If conj.如果，假如

If you ask him，he will help you．如果你请他帮忙，他会帮你的。

If you fail in the exam，you will let him down．

如果你考试不及格，你会让他失望的。

2.unless conj.除非,若不,除非在……的时候（if...not...）

You will fail to arrive there in time unless you start earlier.

如果你不早点动身,你就不能及时赶到那儿。

Unless it rains,the game will be played.除非下雨,比赛将照常进行。

3.so/as long as conj.只要

You may borrow my book as long as you keep it clean.

只要你保持书的清洁，你就可以把我的书借去。

三．关于条件句的时态，常见的有以下三种情况：

1、条件状语从句的主句是一般将来时，那么从句常常用一般现在时。

When I grow up,I’ll be a nurse and look after patients.

我长大后要当一名护士，照顾病人。

2、如果主句是祈使句，那么从句通常要用一般现在时。

If you want to have a chat,call me up.

如果你想聊天，打我电话。
