初中条件状语从句 精讲和练习含答案
初中英语：条件状语从句之公保含烟创作一．条件状语从句的概念条件状语从句，即在某种条件下，一件事情能够发作.在英语中由衔接词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）才华发作，通常译作“假设，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，主句是未来时态时，从句用一般现在时替代未来时态.1.If conj . 如果，假设If you ask him，he will help you．如果你请他辅佐，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,角逐将照常停止.You may borrow my book as long as you keep it clean.只要你坚持书的清洁，你就可以把我的书借去.三．关于条件句的时态，罕见的有以下三种情况：1、条件状语从句的主句是一般未来时，那么从句经常常使用一般现在时.When I grow up, I’ll be a nurse and look after patients. 我长年夜后要当一名护士，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.3、如果主句是含有情态动词时，依据需要从句多用一般现在时.You should be quiet when you are in the reading room.在阅览室时应坚持宁静.四．知识拓展1在以when，before，as soon as等引导的时间状语从句，也适用“主将从现”原则，即如果主句是一般未来时，从句则用一般现在时. I'll tell her the good news when she comes back.当她回来的时候，我将把这个好消息通知她.she will give you a call as soon as she returns.她一回来就会给你电话.2.If条件句的同义句：祈使句，and /or+未来时态的陈说句.Work hard ,and you will make great progress.=If you work hard,you will make great progress.如果你努力学习，你才会取得年夜的提高.Hurry up, or you will b e late.=If you don’t hurry up.you will be late.如果你不快点，你就要迟到了.条件状语从句练习精讲（含谜底）Ⅰ.单项选择1.
