It was as if a great black blanket had been thrown over it. 浓雾 覆盖着整座城市。好像把一个巨大的黑色的毯子扔到它的上面。 3.because, why 引导的表语从句 because , why 也可引导表语从句,但 because 引导的表语从句,主语不能是 reason 或 cause ( 该结构常用 that 引导 ) 。常用于以下句型: · This/That is/was why... 这 / 那是 …… 的原因 · This/That is/was because... 这 / 那是因为 …… · The reason why...is/was that... …… 的原因是 …… From space, the earth looks blue. This is because about seventy - one percent of its surface is covered by water. 从 太空中看,地球是蓝色的。这是因为地球表面大约 71% 被水覆盖。 The reason why he didn’t pass the exam was that he was too careless. 他 没有通过考试的原因是他太粗心了。 四、同位语从句 同位语从句在句中作某一名词的同位语,位于该名词之后,用以说明该名词的具体内容。 1. 常见的后跟同位语从句的名词有: advice 建议 conclusion 结论 demand 要求 doubt 怀疑 fact 事实 hope 希望 idea 主意 information 信息 message 消息 news 消息 order 命令 possibility 可能性 promise 诺言 question 问题 request 请求 suggestion 建议 thought 想法 plan 计划 I made a promise to myself that this year, my first year in high school, would be different. 我对自己承诺:今年,我高中的第一年,会有所不同。 —Is there any possibility that you could pick me up at the airport? —No problem. —— 你有可能到机场接我吗? —— 没问题。 2. 引导同位语从句的连接词有: that, whether, how, where, when, why 等。 Evidence has been found through years of study that children’s early sleeping problems are likely to continue when they grow up. 通过 多年的研究发现:有证据表明孩子的早期睡眠问题很有可能会随着他们的成长继续下去。 She asked a question why there was a delay. 她 问了发生延误的原因。 I have no idea when he will come back home. 我 不知道他什么时候回家。 [ 名师点津 ] 在同位语从句中, that, whether 不作句子成分。 that 无实义, whether 意为 “ 是否 ” , if 一般不引导同位语从句。引导同位语从句的连接词一般都不能省略。 3.that 引导的同位语从句与定语从句的区别 同位语 从句用于解释前面名词的内容,从句本身是一个非常完整的句子,引导词 that 只起引导作用,不在句中作任何成分,一般不可省略。定语从句对其前的名词即先行词加以限制和修饰,从句本身不够完整,因此关系词在定语从句中通常作主语、宾语或表语等成分。 When the news came that the war broke out, he decided to serve in the army. (that 引导的是同位语从句, that 不可省略 ) 当 战争的消息传来时,他决定参军。 As a matter of fact, the news ( that/which ) he told me yesterday is true. (that/which 引导定语从句,可以省略 ) 实际上 ,他昨天告诉我的消息是真的。 五、几组区别 1 . whether 和 if 的用法 (1)whether 和 if 在宾语从句中可以互换,但是作介词宾语时连接词一般用 whether 。 It all depends on whether they will come back. (2) 后面直接跟 or not 时用 whether 。 I didn’t know whether or not he had arrived in Wuhan. (3) 主语从句、表语从句中只能用 whether 。 Whether the meeting will be put off has not been decided yet. The question is whether they have so much money. (4)whether 可以引导同位语从句,用以说明前面的名词的内容, if 则不能。 We ought to discuss carefully the question whether we can do it or not. (5)whether 常与 or 连用表示一种选择, if 不能这样用; whether 也可与动词不定式连用但 if 不能。 The question of whether they are male or female is not important. I have not decided whether to go or not . (6)whether 可引导一个让步状语从句表示 “ 不管 ” 、 “ 无论 ” ,而 if 不能。 Whether he comes or not , we will begin our party on time. 2 . 疑问词+ ever 和 no matter +疑问词的区别 (1) 疑问词+ ever 可引导名词性从句,在从句中要充当一定的成分。 Whoever breaks the rule must be punished. You can choose whatever you like in the shop. (2) 疑问词+ ever 还可引导让步状语从句。 Whoever breaks the rule , he must be punished. Whatever you do , you must do it well. (3)no matter +疑问词只能引导让步状语从句。 No matter what you do , you must put your heart into it. No matter who comes late , he must be punished. 1 位置判断法 根据名词性从句的句子特点及其所处的位置,判断出属于哪一种从句,从而确定连词的种类。 (1)________ some people regard as a drawback is seen as a plus by many others. A.Whether B.What C.That D.How 答案 B 解析 句 意:一些人眼中的缺点是别人眼中的优点。从句中缺宾语,只能用 what 来引导, that 引导主语从句不作成分。 (2)One reason for her preference for city life is ________she can have easy access to places like shops and restaurants. A.that B.how C.what D.why 答案 A 解析 系 动词 is 之后是一表语从句,从句的结构完整,不缺少任何成分,所以用 that 引导。 2 语序判断法 一般来说,名词性从句中 ( 当然不只是名词性从句,其他从句也是如此 ) ,从句的语序要用陈述语序。 When changing lanes, a driver should use his turning signal to let other drivers know________. A.he is entering which lane B.which lane he is entering C.is he entering which lane D.which lane is he entering 答案 B 解析 which 引导的句子作 know 的宾语,句子用陈述语序。故 B 项为正确答案。 3 句子成分分析法 看从句缺不缺成分,不缺就用 that, whether/if ,缺成分就用 wh -类连接词 ( 包括 how, because 等 ) 。 (1)We haven’t discussed yet ________ we are going to place our new furniture. A.that B.which C.what D.where 答案 D 解析 句 意:我们还没有讨论把我们的新家具放在哪里。由句意知, discussed 后面的宾语从句中缺少地点状语,因此选择 D 。 (2)As a new graduate, he doesn’t know ________ it takes to start a business here. A.how B.what C.when D.which 答案 B 解析 句 意:作为一名新毕业生,他不知道需要什么才能在这里创业。空格后的从句中 takes 是动词,其后缺少宾语,所以引导该宾语从句的连接词要用 what 。查看更多
