certain.,注意：从句作主语时，就算是句子意思完整，都要加上从属连词,that,他星期三是否来这里还不肯定的。,Whether he will come here on Wednesday is not certain.,注意：主语从句表示“是否”只用“,whether”,而不用“,if”,主语从句,主语从句有时用“,it”,作形式主语，把真正的主语放在后面，以避免头重脚轻。,It is known to us that he will come here.,It+be+,形容词,that,从句,It is necessary that,有必要,It is important that.,重要的是,It is obvious that,很明显,It+be+-ed,分词,that,从句,It is believed that,人们相信,It is known to us/all

this museum the one that you visited?,注意：这种句子考试时一定要记住这句话：名词前（尤其是单数可数名词前）一定要有限定词。然后把句子变换成陈述句，接着判断句子是属于哪种从句再完成。,(,表从,),(,定从,),(,定从,),宾语从句,在句中充当及物动词或介词宾语的句子叫做宾语从句。,我不知道你会来这里。,I dont know,（,that,）,you will come here.,注意：,that,在从句中不充当任何成分，在口语或非正式的文体中常常被省去。,我不知道他来不来。,我想知道他来还是不来。,你们是在谈论着他来还是不来吗？,他不在乎天气是否好。,I dont know whether/if he will come.,I want to know whether he will come or not.,Are you talking

it,impossible,that he should finish the work in two days.,注意：如果主句中有形容词或名词作宾语补足语时，一般用,it,来作形式宾语，把从句放在宾补后面。,同位语从句,在句中用作同位语的从句叫做同位语从句。同位语从句一般放在如,idea,news,fact,promise,suggestion,belief,truth,等含有丰富内涵的词语后面，,用来说明前面那个词的具体内容,。一般说来，同位语从句都用,that,来作连接词，而且不能省略,。也可用,how,when,where,等。,他给了她一个承诺，他会在两个月后回来。,He gave her a promise that he would come back after two months.,试区分以下句子,Do you know the fact that he stole the car?,Do you know the fact that they were talking about?,注意：,1.,如果是定语从句，它的从句肯定是不完整的，关系词肯定在句中充当成分的；而同位语从句中的,that,只起连接作用。,2.,定语从句是对先行词起修饰作用，而同位语从句则解释说明先行词的具体内容。,(,同从,),(,定从,),一、同位语从句与定语 从句的相似之处,1,、两种从句都可以译成定语,e.g.,The news,that our team has won the final match,is encouraging.,（,同位语从句）,我们队取得决赛胜利的,消息令人鼓舞。,The news,that you told us,is really,encouraging.,（,定语从句）,你告诉我们的,消息真的令人鼓舞。,2,、两种从句都可以用,that,引导,e.g.,The suggestion,that students should learn something practical,is worth considering,.,（,同位语从句）,学生应该学些实用的东西的,建议值得考虑。,The suggestion,that is worth considering,is that the students should learn something practical.,（,定语从句）,值得考虑的,建议是学生应该学些实用的东西。,一、同位语从句与定语 从句的相似之处,二、同位语从句与定语 从句的,不同之处,1,、从句的作用不同：同位语从句用来进一步,说明前面名词的内容；定语从句用来修饰、,限定前面的名词。,e.g.The news,that our team has won the final match,is encouraging.,（,从句说明“消息”的内容：,我们队取得了决赛胜利。,）,The news,that you told us,is really,encouraging.,（,从句对“消息”加以限定：是,你告诉我们的,，,而非来自其他渠道。但消息是何内容却不得而知。）,二、同位语从句与定语 从句的不同之处,2,、引导从句的关联词,that,的功能不同：,that,引导同位语从句时是一个纯连词，不充当任何成分；而引导定语从句的,that,是关系代词，既指代先行词又须在从句中充当成分。,e.g.1)Dad made a promise,that,he would buy me CD player if I passed the English test.,（,that,不充当任何成分）,2)Dad made a,promise,that,excited all his children.,（,that,指代,promise,，,又在从句中充当主语。）,Tell the difference,1.The news,that the plane would take off on time,made everybody
