这类形容词或过去分词有sure，glad，certain，pleased，happy，afraid，surprised，satisfied等，连词that可省略。

① I am not sure what I ought to do.

② I'm surprised that I didn't see all that before.

③ Mother was very pleased her daughter had passed the exams.

3、句子结构：主句+连词(引导词)+ 宾语从句

She asked if these answers were right.

We can learn what we do not know.

4、宾语从句的引导词

(1) 从属连词that

① He told us that he felt ill. 他对我们说他感到不舒服。

② I know（that）he has returned.我知道他已经回来了。（此处that可省略）分析：从句中________(缺/不缺)句子成分，____（有/无）实际意义，只起连接作用，所以填that

(2)从属连词if/whether。如：

① I doubt whether he will succeed. 我怀疑他是否会成功。

②I don’t know if you can help me. 我不知道你能否帮助我。

分析：从句中________(缺/不缺)句子成分，意为___________，

只起连接作用，所以填if/ whether

情况whether if

①从句置于句首时

②从句作介词的宾语时

③从句作discuss，doubt （doubt用于肯定

结构时）等动词的宾语时

④与or not 或动词不定式直接连用时

⑤用if容易产生歧义时

⑥从句为否定句时

①___________ she will come or not is still a question．她是否能来还是个问题。

②I'm interested in _________ he likes English．我关心的是他是否喜欢英语。

③ Let me know _________ or not he will come. 让我知道他是否能来。

⑥ People doubt ___________ he is a thief. 人们怀疑他是否是小偷。

⑦ He asked ________ I didn’t come to school yesterday.他问我昨天是否没来学校。注意：Please let me know if you like the book．可理解为：

If you like the book，please let me know．你如果喜欢这本书，请告诉我

(3)连接代词who，what，whom，whose，which

①Do you know who has won the game？你知道是谁赢得这场游戏么？分析：从句中缺____语，指代_______（人/ 物），意为_________，所以填who

②I wonder what he’s writing to me about.我不知道他要给我写信说什么事。
