thatifwhether连接代词：在从句中作主语、宾语、表语或定语连接代词：who,whom,whose,what,which,whoever,whatever,whichever等连接副词：在从句中作状语when,where,why,howit作形式主语的主语从句：

It+be+形容词+that从句

It+be+名词(词组)+that从句It+be+过去分词+that从句

It+不及物动词(短语)+that从句其他句型Thathistheorywasflawedsoonbecameobvious他的理论是有瑕疵的，这很快就变得显而易见。That

smokingisharmfultohealthisknowntoeveryone.

吸烟有害健康，这是大家都知道的。

（that不充当句子成分，没有实际意义，仅为连接作用，但是不可省略。）从属连词：that,whether,if用法从属连词：that,whether,if用法Whetherlifeexistsonotherplanetsisnotclearyet.

Itisstilldoubtfulwhether/ifshewillplaytherole.(whether/if不充当句子成分，仅为连接作用，意为“是否”。if

不可引导位于句首的主语从句。)连接代词：who,whom,whose,what,which,whoever,whatever,whichever等用法Whowillbethewinnerisstillunknown.

Whatever

youdoshoulddonoharmtoothers.

(连接代词在从句中作主语、宾语、表语或定语起连接作用，有实际意义。)注意：疑问词+ever也可引导主语从句，但不含疑问，往往含有强调作用，意思是“无论…”如：whoever

无论谁whatever

无论什么whichever

无论哪个whenever无论什么时候wherever无论哪里……它们在句子中担任成分，不能省略，语序为陈述语序“疑问词＋-ever”和“nomatter＋疑问词”引导的让步状语从句1.

Whateverarouseshisinterestcanbefoundintheschoollibrary.（Whatever引导主语从句）2.Eateithercakeyoulikeandleavetheotherforwhoevercomeslate.（whoever引导宾语从句）3.Youcantakewhicheverseatyoulike.（whichever引导宾语从句）

“特殊疑问词＋-ever”不可与“nomatter＋特殊疑问词”互换的情形:whatever，whoever和whichever除了引导让步状语从句外，还可引导名词性从句，此时不可与nomatterwhat，nomatterwho和nomatterwhich互换。连接副词：when,where,why,how用法Whysheleftisn'timportant.

Whenwewillsetoffhasn’tbeendecided.(when,where,why,how在从句中作状语，起连接作用，有实际意义。)主语从句太长怎么办？Thatallcountriesworktogetherisimportant.

用一个

It

来解决问题！Itisimportantthatallcountriesworktogether.

=Itisn'tclearwhether/ifhe'llcomehere.注意：主语从句位于句首时,不能用if

引导,主语从句后置时,

It

来解决问题！18It作形式主语(1)It+be+形容词（obvious,true,surprising,wonderful,possible,likely,certain)+that从句(2)It+be+过去分词(said,reported,thought,expected,decided,announced,
