It’s a pity(that)you’re leaving.真遗憾你要走了。 That we are invited to the concert this evening is good news to us. 我们被邀请去参加今晚的音乐会,这对我们来说是个好消息。 (二)宾语从句 1.常见的可以接that从句作宾语的动词有see,say,know,imagine,discover,be-lieve,tell,show,think,consider等。在可以接复合宾语的动词之后,如think,make,consider等,可以用it作形式宾语。如: Do you know(that)he has joined the army? 你知道他参军了吗? I’m sure(that)he will pass the exam. 我确信他会通过考试。 We think it highly probable that he is dead. 我们认为他很可能已经死了。 We consider it necessary that he should improve his pronunciation. 我们认为他有必要改进他的发音。 He has made it clear that he will not give in. 他不会屈服的,这一点他已明确表示了。 2.that从句一般不能充当介词宾语,偶尔可作except,in的宾语。如: He is a good student except that he is a little bit careless. 他是个好学生,就是有点粗心。 He differed from his classmates in that he devoted his spare time to reading. 他和他的同学不同的地方在于他把课余时间用在了读书上。 其他介词后面需要用that从句作宾语时,必须用it作形式宾语。如: You may depend on it that I shall always help you. 你要相信我会一直帮助你的。 (三)表语从句 that引导表语从句时,不可省略。如: My decision is that all of us are to start at 6 o’clock tomorrow morning.我的决定是我们所有人明天早上6点出发。 (四)同位语从句 连词that引导同位语从句时,应放在某些抽象名词之后,如:fact,hope,desire,thought,suggestion,idea,news,problem,possibility等,对前面的名词起补充说明的作用,连词that只起引导同位语从句的作用,在从句中不充当任何成分,通常情况不能省略。如: There’s a feeling in me that we’ll never know what a UFO is—not ever. 我有一种感觉,我们将永远不会知道不明飞行物是什么——永远都不会。 三、whether/if(是否) (一)表语从句和同位语从句只能用whether引导不能用if;当主语从句放于句首时,也只能用whether引导不用if;当it作形式主语,主语从句放在句末时, 用whether或if引导均可;discuss后必须用whether引导宾语从句。如: Whether the meeting will be given is still a problem.(主语从句放于句首) =The problem is whether the meeting will be given.(表语从句) =I have no idea whether the meeting will be given.(同位语从句) 是否要开会仍然是个问题。 It is doubtful whether/if he will come here.(主语从句放于句末) 他是否要来还不确定。 (二)宾语从句 1.在及物动词后: (×)I don’t care whether he doesn’t come.(whether从句中不能用否定式) (√)I don’t care whether/if he comes or not. (√)I don’t care whether or not he comes. (×)I don’t care if or not he comes. (√)I don’t know whether to go there. 2.在介词后: 在介词后只用whether,不用 if。如: It depends on whether you can do
