If,unless专项练习
if和unless区别和练习
Chapter1语法If和unless引导的条件状语从句我们用if引导的条件状语从句来讨论可能的条件以及该条件成立时可能的结果。
一.学习if引导的条件状语从句的用法，我们可先从如下的口诀入手：If条件句不一般，几个要点记心间；条件句，放在前，逗号要句中间条件句表可能，主句多用将来时；IwilltellherifIseeher.如果我见到她，我就会告诉她。
主句中的will也可以用情态动词can,may或might等代替。
如：Eg.Iftheyarefriendly，Imightinvitethemtotheparty.如果他们很友善，我可能会请他们去参加聚会Ifwehurrynow,wecanstopforcoffeelater.如果我们现在抓紧时间，就可以稍后去喝咖啡注意：在条件句中，主句部分只能使用动词will的一般将来时，不能使用begoingto的结构二.Unless的条件句表示在特定条件下，才决定做或不做一件事，中文用的连接词一般是“除非”和“否则”。
如：除非刮台风，否则演唱会将如期进行。
在英语中，我们可以用unless表达这个意思，相当于ifnot。
以这个句子为例：Theconcertwillbeheldasscheduleunlessthereisatyphoon.=theconcertwillbeheldasscheduleifthereisnotatyphoon Shewillkeeponsingingunlesssheistoldtostop.她会一直唱下去，除非有人叫她停止=shewillkeeponsingingifsheisnottoldtostopA.------Goodidea!Unlessit_______.A.rainsB.doesn’trainC.rainD.won’train7.-----CanIchangethejacketforanotherone______itdoesn’tfitmewell?-----Ofcourse.A.unlessB.ifC.thatD.though8.Nobodycanlearnmathswellheworkshardonit.AifBunlessCthoughtDhowever9.Iffishawayfromwater,theydie.Aaretaking,won’tBaretaken,willCarebeingtaken,willDtake,won’t10.Eachstudentcanaskteachersforhelpifhehowtoworkouttheproblem.AwillknowBwon’tknowCdon’tknowDdoesn’tknow练习:4.____theclouds,youwouldfindtheairplaneintheskyeasily.A.WereitnotforB.IfithadnotbeenforC.IfitwerenotD.Haditnotbeenfor5.IfIhadknownthat,I___so.A.wouldn’tdoB.won’tdoC.didn’tdoD.wouldn’thavedone6.Ifit___sohard,we’dgototown.A.isn’trainingB.weren’trainingC.doesn’trainD.isn’tgoing torain1.答案A2答案C3.答案B4.答案A5.答案D6.答案B7.He_____youifyou____toseehimthatafternoon.A.mighttell,weregoingB.told,weregoing7.unless…“除非，如果不……”(=if…not)[例句]wIshallgotomorrowunlessitrains.如果不下雨，我明天去。
