这是一份小升初英语语法专项培优突破 第16章：连词（2）从属连词，共5页。教案主要包含了改正下列句中的错误等内容，欢迎下载使用。
I think(that) he likes ftball.
我想他喜欢足球。
that引导名词性从句(主语从句、表语从句、宾语从句和同位语从句)和定语从句，本书只介绍宾语从句。
1.that在宾语从句、间接引语中可以省略，主句与从句时态一致。
I think(that) he is tired.我想他累了。
I thught(that) he was tired.
注意
要特别注意主句与从句时态的呼应。如果主句是过去时，从句一律改为过去的时态，详见第二十章宾语从句。
2.如果主句的动词是 think， believe…；如果主句的主语是第一人称，变为否定句时，要否定主句，译成中文时，则否定从句。
I believe yu will leave here.
我相信，你会离开这儿的。
I dn't believe yu will leave here.
我相信，你不会离开这儿的。
必背！
I hpe that～我希望～
I think that～我认为～
I say that～我说～
I knw that～我知道～
I find that～我发现～

be sure that～确认～
be glad(happy) that～很高兴～
(以上的that都可以省略)
2) when，while，till，until，since…
When he arrives there he will call yu.
他到达那儿以后，他会给你打电话。
when， while， till， until， since， after， befre， as sn as等是连接时间状语从句的连词。在时间状语从句中要特别注意时态的搭配：当主句是将来时，从句要用一般现在时。
注意
while所引导的从句的谓语动词只能是延续性的，不能用点动词。(如begin，stp…)
When I arrived there， it was raining.
当我到那儿时，天正在下雨。
I entered the rm while(when) Li Ming was talking with her.
我进屋时，李明正在和她谈话。

直到我做完作业，我才上床睡觉。

老师教给我们如何做这工作之后，我们才会开始做。

比较
连词连接从句不同，意思不同。
He had been in China befre the war was ver.
战争结束前，他已经在中国了。
=The war was ver befre he came t China.
=The war had been ver befre he came t China.
战争结束后，他来到中国。
I have learned mre than tw thusand English wrds since I began learning English tw years ag.
自从两年前我开始学习英语以来，我已经学习了两千多个英语单词了。
注意
since引导的是一个过去时的句子，说明自当时以来到现在(自从两年前以来)，主句一般要用现在完成时。
As sn as I get enugh mney，I'll buy it.
我一得到足够的钱，就买它。
3) because：因为，连接原因状语从句
She didn't g there，because she was ill.
因为她病了，所以她没去那儿。
1.回答Why问句时，只能用because，不能用fr或 as.
Why are yu late？
你为什么迟到？
Because I met a traffic accident n my way here.
因为在我来这儿的路上，遇到了车祸。
2.汉语中，我们经常说因为……所以，但在英文中有了because，就不能再用s。
(×)Because he was tired， s he culdn't walk there.
因为他累了，所以他不能走到那儿了。
4) if，thugh (althugh)
If it desn't rain，we'll g t the park.
如果不下雨，我们就去公园。
Thugh I was tired， I still wrked hard.
虽然我很累，可是我仍然努力地工作。
1.if：如果(引导条件从句)
Yu can pass the exam if yu study hard.
如果你努力学习，你会及格的。
2.thugh，althugh：虽然(引导让步状语从句)和原因状语从句一样，如果用了thugh，althugh (虽然)就不能再用but(但是)。
Althugh(Thugh) I live near the sea， I'm nt a gd swimmer.
=I live near the sea，but I'm nt a gd swimmer.
虽然我住在海边，可是我游泳并不好。
注意
注意时态一致，和时间状语从句一样。主句是将来时之时，从句要用一般现在时。
5) s…that：太……以致……
He is s ld that he can't wrk. = He is t ld t wrk.
他太老了，不能工作。
The bx is s heavy that I can't lift it.
=The bx is t heavy fr me t lift.
箱子太沉了，我抬不起来。
The girl is s beautiful that everybdy likes her.
这个小女孩太漂亮了，每个人都喜欢她。
注意
注意此句型与t…t的互换。
s…that在肯定句中不能转换成t…t…。
