标题: 英语语法:引导主语从句
下面与大家分享“引导主语从句的关联词的类别”~
(1)从属连词that.如:Thatthey were in truth sisters was clear from the facial resemblance between them.
很明显,她们确是亲姐妹,她们的脸型很相似。
(2)从属连词whether.如:
Whether he’ll come here isn’t clear.他是否会来这里还不清楚。
(3)连接代词who,whom,whose,what,which,whoever,whatever,whichever
连接副词 where,when,how,why.如:

How this happened is not clear to anyone.这事怎样发生的,谁也不清楚。
Whoever comes is welcome.不论谁来都欢迎。
Wherever you are is my home —— my only home.你所在的任何地方就是我的家——我唯一的家。
解释:
1.主语从句能用it作形式上的主语。常以it作形式主语的句型有:
A.It+be+形容词(obvious,true,natural,surprising,good,wonderful,funny,possible,likely,certain,probable,etc.)+that从句。如:
It is certain that she will do well in her exam.毫无疑问她考试成绩会很好。
It is probable that he told her everything.很可能他把一切都告诉她了。
B.It+be+名词词组(no wonder,an honor,a good thing,a pity,no surprise,etc.)+that从句。如:
It’s a pity that we can’t go.很遗憾我们不能去。
It’s no surprise that our team should have won the game.我们没赢这场比赛真意外。
C.It+be+过去分词(said,reported,thought,expected,decided,announced,arranged,etc.)+that从句。如:
It is said that Mr.Green has arrived in Beijing.据说格林先生已经到了北京。
It is reported that China has sent another man-made earth satelliteinto orbit.
据报道中国又成功地发射了一颗人造地球卫星。
D.It+seem,happen等不及物动词及短语+that从句。如:
It seems that Alice is not coming to the party at all.Alice似乎不来参加晚会。
It happened that I was out that day.碰巧我那天外出了。
E.It+doesn’t matter(makes no difference,etc.)+连接代词或连接副词引起的主语从句。如:
It doesn’t matter whether she will come or not.她是否来这无关紧要。
It makes no difference where we shall have the meeting.我们在哪里开会毫无区别。
F.当that引导的主语从句出现在疑问句中时,要以it作形式主语,而把主语从句后置。如:
Is it true that the scientist will give us a lecture next week?下周那位科学家将给我们作报告是真的吗?
Does it matter much that they will not come tomorrow? 他们明天不来很要紧吗?
G.当主语从句出现在感叹句中时,要以it作形式主语,而把主语从句后置。如:
How strange it is that the children are so quiet! 孩子们这么安静真奇怪!
2.注意连接代词whoever,whatever,whichever等引导主语从句的含义。
Whoever comes will be welcome.(whoever=theperson who)来的人将受到欢迎。
Whatever he did was right.(whatever=thething that)他所做的事情是正确的。
Whichever of you comes in will receive a prize.(whichever=anyone of you who)你们当中不论哪个进来将会得到奖。
