我所说的有错误之处吗？ These two areas are similar in that they both have high rainfall in summer. 这两个地区的相似之处在于夏天降水都很多。 I’m not certain whether they will struggle for a better life. 我不确定他们是否会为了更好的生活而奋斗。 I find it strange that she doesn’t want to go. 她居然不想去，我觉得奇怪。 注意：宾语从句一般用陈述语气，但是，当主句的谓语动词为advise，insist(坚决主张)，suggest(建议)，require，request，order等表示请求、命令、要求、主张的动词时，从句谓语要用虚拟语气，即用“should＋动词原形”(should可以省略)。 She insisted that we (should) go to the exhibition with her. 她坚决要求我们和她一起去看展览。 三、表语从句 表语从句在复合句中作表语，出现在连系动词之后，一般结构为“主语＋连系动词＋表语从句”。 可接表语从句的连系动词有be，look，remain，seem，sound等。 The question is whether he could compose such nice music within two days. 问题是他是否能在两天之内创作出那么好的音乐。 You look as if you slept badly. 你看上去仿佛没睡好觉。 The fact remains that we are still not advanced enough. 事实是我们仍旧不够先进。 注意： 1.表语从句实际上是对主语进行补充说明，从句表达的是主语的内容。 The fact is that he often feels tense while he is on the stage. 事实是他在台上时经常感到紧张。 2.主句的主语是名词advice，suggestion，order，request，requirement等时，表语从句应用虚拟语气，即谓语动词用“(should＋)动词原形”。 My suggestion is that we (should) consider all the aspects before making a decision. 我的建议是我们在做决定前应考虑到所有方面。 3.because，why引导的表语从句。 This/That is why...这/那是……的原因 This/That is because...这/那是因为…… He failed.That is because he didn’t work hard. 他失败了。那是因为他没有努力工作。 He didn’t work hard.That is why he failed. 他没有努力工作。那是他失败的原因。 4.主句主语为reason时，表语从句的引导词要用that，一般不用why或because。 The reason for such a serious accident is that the driver was drunk. 发生如此严重的一起事故的原因是司机喝醉了。 四、名词性从句要注意的难点 1.用whether而不用if的情况 (1)引导主语从句和表语从句时；(2)引导介词的宾语从句时；(3)引导词与or not连用时；(4)引导词后接to do时；(5)有些动词如leave，put，discuss，decide等后的宾语从句。 We discussed whether we should hold a meeting. 我们讨论了是否应该举行会议。 It depends on whether we have enough time. 这取决于我们是否有足够的时间。 I don’t know whether or not the report is true. 我不知道这份报告是不是真的。 2.that与what引导名词性从句的区别 that在从句中不充当句子成分，也没有含义；what可以在从句中作主语、表语、宾语，意思是“……的事情，什么样的”。 That he failed in the test again really puzzled us. 他又一次没通过考试，这真让我们感到迷惑不解。(that在主语从句中不作成分，不可以省略) These photographs will show you what our village looks like. 这些照片将向你展示我们村的面貌。(what在宾语从句中作介词like的宾语) 3.wh-与wh-ever引导名词性从句的区别 连接词what，which，who分别表示“……的东西或事情”“哪一个”“谁”，表示疑问含义；而whatever，whichever，whoever分别相当于anything that，any...that，anyone who，意为“无论……”，强调一切情况。试比较： What you choose to wear should be clean. 你选择穿的衣服应该是干净的。 Whatever you choose to wear should be clean. 无论你选择穿什么衣服，都应该是干净的。 返 回 达标检测 完成下列语段，尽可能多地使用名词性从句。 据报道，今天早上罗马街街角出事故了。当时没有人看到究竟发生了什么事。谁将对这次事故负责仍在调查中。警察现在应该做的是尽快查明什么导致了这次事故。或许原因是司机太累了而没能及时停车。那位司机不承认拐弯时超速了。警察怀疑他所说的是否属实，决定进行进一步调查。 1. there was an accident at a corner of the Roman Street this morning.No one saw 2. then. 3.______________________________________ is still under investigation. 4. is to find out 5._____________________.
