2、析】疑问词+ever引导的从句和no matter+疑问词引导的从句究竟有什么区别呢?.疑问词+ever包括疑问代词+ever和疑问副词+ever疑问代词:whatever,whichever,whoever,whomever疑问副词:whenever,wherever,however.疑问词+ever与 no matter+疑问词引导从句时的区别1.疑问词+ever引导名词性从句,不可以与no matter+疑问词互换使用。例如:Whoever comes to the party will receive a gift.来参加晚会的人都会收到一份礼物。(Whoever意为“无论是谁”,引导

3、名词性从句时,不可以与no matter who互换。)2.引导让步状语从句,可以与no matter+疑问词互换使用。例如:The quality will be the same,whichever(=no matter which)of them you choose.它们当中无论你选哪一个,品质都一样。(whichever意为“无论哪一个”,引导让步状语从句时,可以与no matter which互换。)【点拨迷津】简单说来:疑问句+ever可以引导名词性从句,也可以引导让步状语从句,但是no matter+疑问词只可以引导让步状语从句,也就说前者适用的范围比后者大。所以选项中两者都有

4、的情况下,我们尽量选择使用范围较广的疑问词+ever,答对的可能性较大。(2019北京高考)Whatever stage of life youre at,wherever you go and whatever project you do in GDA,youll create positive changes in a poor and remote community.(高考典句)无论你处于什么人生阶段,无论你去哪里,无论你在GDA中从事的项目如何,你都将在一个贫穷而遥远的社区中创造积极的变化。3.疑问词+ever引导名词性从句时的注意事项。Whatever我们知道相当于No matt

5、er what,但是在引导名词性从句时相当于anything that,我们来分析以下的例句。例如:Whatever he did was right.=Anything that he did was right.(正确)Anything he did was right.(错误)他无论做什么都是正确的。(Whatever意为“无论是什么”,相当于anything that,anything是句子中的主语,同时充当先行词,后面that为定语从句中的引导词,that在定语从句中充当主语成分,并且不能省略。)4.whoever同样在引导名词性从句时相当于 anyone who的含义。例如:Who

6、ever breaks this law deserves a fine.=Anyone who breaks this law deserves a fine.(正确)Anyone breaks this law deserves a fine.(错误)违反本法者应予以罚款。(Whoever意为“无论是谁”,相当于anyone who,anyone是句子中的主语,同时充当先行词,后面who为定语从句中的引导词,who在定语从句中充当主语成分,不能省略。)【内化用】The effect of pushing the button is the same _does it.不论是什么人去按按钮,

7、其效果都是一样的。_is supposed to win the prize.第一个回来的理应赢得奖励。I am ready to do _.我准备好做你想让我做的任何事情了。no matter whoWhoever comes back firstwhatever you want me to翻译句子。无论你做过什么,我都会接受。译:_ I will accept whatever you did.译:_Whatever you did,I will accept.我会接受你做过的任何事情。【常温故勤总结】whatever和no matter what,名词性从句不可换,让步状语从句中,刚好

8、能互换。类似疑问词,用法都一样。常背例句多,自然就会了。.单句语法填空1._happened,he wouldnt be scared.2._says so,it cant be true about that.3._dictionary you take,you will have to pay at least 10 dollars.4.You may invite _ you like to your birthday party.5._he goes(may go),Ill follow him.6._I visited him,he was always busy working.7
