It作形式主语和it引导强调句的比较

主语从句常用it作形式主语，一般常用句型为：It is+{名词/形容词/过去分词}+主语从句例如：

It is still a question whether she will come or not.

It is strange that you should like him.

It is still unknown which team will win the match.

以上内容参考：百度百科-主语从句

主语从句的时态不受主句时态的影响和限制（1）That he finished writing the composition in such a short time surprised us all.（2）Whether we will go for an outing tomorrow remains unknown.（3）Who will be our monitor hasn't been decided yet.（4）Whom we must study for is a question of great importance.（5）What caused the accident remains unknown.（6）Whatever you did is right.（7）Who the watch belongs to is unknown.（8）What we need is time.（9）What we need are good doctors.

主语从句在复合句中作主句的主语,引导主语从句的词有从属连词that, whether以及连接代词who, what, which, whoever, whatever, whichever和连接副词when, where, why, how等.例如:1、That she was chosen made us very happy.她当选了使我们很高兴.2、What caused the accident is a complete mystery.是什么导致了这次事故还完全是一个谜.3、Whether she will come or not is still a question.她是否来还是一个问题.4、Which team will win the match is still unknown.哪个队会赢得这场比赛还不知道.5、Whoever comes to the party will receive a present.参加聚会的每一个人都将收到一份礼物.6、When they will start has not been decided yet.他们何时出发还没决定.注意:上述例句中的主语从句都是放在句首,但有时为了使句子结构平衡,避免"头重脚轻",常用it作形式主语,而把从句放在后面.例如:It is a pity that she has made such a mistake.她犯了这样一个错误,真是遗憾.It depends on the climate whether they are going shopping today.他们是否今天去购物还得看天气情况.这样就构成了下面一些常用句型:1)It is + adj. / n. +从句It is a pity/shame that...遗憾的是……It is possible that...很可能……It is unlikely that...不可能……2)It +不及物动词+从句It seems/appears that...似乎……It happened that...碰巧……3)It + be +过去分词+从句It is said that...据说……It is known to all that...众所周知……It is reported that...据报道……It is believed that...据信……;人们相信……It is suggested that...有人建议……It must be pointed out that...必须指出……It has been proved that...已证明…….例如:It is believed that at least a score of buildings were damaged or destroyed.据信,至少有二十座楼房遭到破坏或彻底毁掉.It is suggested that the meeting should be put off.有人建议会议延期召开.It's reported that three people were killed in the accident and five were hurt badly.据报道,事故中三人丧生,五人重伤.It is known to all that Taiwan is an inseparable part of China.众所周知,台湾是中国不可分割的一部分.扩展资料宾语从句用以区分 主语从句的几个特征：1、 引导词：what\which\whose\when\whether\if\where2 语序：宾语从句必须是用陈述语句。（名词性从句都是陈述语序）如：I think that you must work harder.宾语从句的引导词、 连接词的区别、 否定转移等现象。补充： 从句的语序永远是 陈述句。
