rules
一个句子一个谓,
两个动词连成对,
没有连词用非谓。
,在宾语从句中没有实际意义,只是起引导从语的作用。
1)作动词的宾语从句
We all know (that) ess calls for hard work.
我们都知道成功需要付出艰辛的劳动。
We knew (that) he had made a mistake.
我们知道他犯了一个错误。
2)在某些be+形容词的结构后面也可以跟that引导的宾语从句。如sure, certain, glad, pleased, happy, afraid, surprised, sorry等。
I am sure that I have posted the letter.
我的确把那封信寄了。
I am afraid that you are right.
恐怕你是对的。
【要点拓展】
一般说来引导宾语从句的that可以省略。如果有多个that引导的宾语从句,第一个that可以省略,其他一般不省略。
I know (that) you are right.
我知道你是对的。
The doctor told me (that) I should take more water and that things would get better very soon医生告诉我要多喝水,情况很快就会好转。
/if在做“是否”解时引导宾语从句,常放在动词know,ask,care,wonder,find out等之后。在口语中常用if。 whether /if在宾语从句中不作任何成分,但含有“是否”的含义,在句子中不可省略。
I don’t know whether/ if this bike is hers.
我不知道这辆自行车是否是她的。
Can you tell me whether/ if your father joined the Party in 1990?
你能告诉我你父亲是不是1990年入党的?
