I他马克思耨Itmakesnodifferenceif(whether).
I他马克思耨Itmakesnodifferenceif(whether).
I他马克思耨Itmakesnodifferenceif(whether).
由于这个句子实际上的主语(if/whether引导的主语从句)太长,而用it作为句子的形式主语,make是句子的谓语
Itmakesnodifferencewhetherhewillattendthemeetingornot.他是否会参加会议都无关紧要.
Itmakesnodifferenceifhedoesn'tknowme.
他知不知道我并没什么区别.
it构成的主语从句
(1)由连词that引导的主语从句,在大多数情况下会放到句子的后面,而用代词it作形式主语.如:
Itiswell-knownthattheearthmovesaroundthesun.众所周知,地球围绕太阳转.
需要注意的是,it作形式主语代替主语从句时,要注意和as引导的定语从句的区别.试比较:
ItwasreportedthattheUSwasundertheterroristattack.(主语从句,有that,无逗号)
Aswasreported,theUSwasundertheterroristattack.(定语从句,无that,有逗号)上两句意为“据报道,美国遭到恐怖分子的袭击”.
(2)常见用it作形式主语的复合句结构
Itisafact(agoodidea/apity/ashame/nowonder/goodnews…)that…如:
It'sapitythatyoumissedthefilm.你没有看那部电影真是太遗憾了.
Itisnecessary(clear/true/strange/important/wonderful/possible/likely…)that…
需要注意的是,这类主语从句中,谓语动词很多为“(should)+动词原形”,即要用虚拟语气.如:
Itisnecessarythatyou(should)masterthecomputer.你很有必要掌握电脑.
ItisimportantthatastudentlearnEnglishwell.学生学好英语很重要.
It'sclearthattheybadlyneedhelp.很明显,他们急需援助.
Itislikelythatahurricanewillarrivesoon.飓风很可能马上就要到达了.
Itisreported(well-known/hoped/thought/expected/said/believed/decided/suggested/ordered…)that…如:
Itissaidthathewaskilledintheearthquake.据说他在地震中丧生了.
Itseems(happened/appears/doesn'tmatter/makesnodifference/…)that…如:
Itseemsthattheywillwinthegame.看起来他们好像会赢得这场比赛.
Itmakesnodifferencewhetherhewillattendthemeetingornot.他是否会参加会议都无关紧要.
