三、宾语从句:用作宾语的句子叫宾语从句,可以充当动词或介词的宾语。
i felt that she has a strong will.意志
i wonder 想知道what you call叫,称呼 these flowers.
i’ll see whether i can help you.
注:① 宾语从句中的连词 that 有时可以省略;
② whether 和if 都表示“是否”的意思,但如果作为介词的宾语,或后面有---or not,或用于主语从句放在句首,引导表语从句中,只用whether ,而不用if.
whether she likes the present礼物 is not clear清楚 to me .
he didn’t say whether or not he’d be staying here.
③宾语从句中的时态呼应,
当主句动词是现在时,从句根据自身的句子情况,而使用不同时态。
当主句动词是过去时态(could, would除外),从句则要用相应的过去时态,如一般过去时,过去进行时,过去将来时等;当从句表示的是客观真理,科学原理,自然现象,则从句仍用现在时态
四、同位语从句:与先行词同位或等同的从句叫做同位语从句。
同位语从句的先行词大多为:fact 事实、news消息、idea观点、thought 想法、reply回答、report报告、remark 评论、doubt 怀疑、suggestion 建议、 conclusion 结论、hope 希望、question 问题、opinion观点等引导词多为that, 有时也可用whether、when、where、why、how、what等。

i’v expressed表达 the opinion that she can act.演戏
the report that she was going to resign 辞职was false.假的,不真实的
