◆(北京卷)The best moment for the football star was when he scored the winning goal. 在这个足球明星看来,最美好的时刻是他射进制胜球的时候。 三、其他连接词引导的表语从句 1.as if/as though引导的表语从句

as if/as though意为“好像,仿佛”,引导的表语从句常跟在系动词(be,seem, appear, look, taste, sound, feel, smell等)之后。若表语从句所述的是非真实的情况,从句用虚拟语气;若所述的是事实或是极可能发生的情况,从句用陈述语气。

◆The thick smog covered the whole city. It was as if a great black blanket had been thrown over it. 厚重的烟雾覆盖着整个城市,好像把一张厚厚的黑色的毯子扔到它的上面。 2.because,why引导的表语从句 (1)This/That/It is why+表语从句(表结果) “这/那就是……的原因”

(2)This/That/It is because+表语从句(表原因) “这/那是因为……”

1.(2018·江苏卷)By boat is the only way to get here, which is how we arrived. 2.(2016·北京卷)The most pleasant thing of the rainy season is that one can be entirely free from dust. 3.(浙江卷)“Every time you eat a sweet, drink green tea.” This is what my mother used to tell me. 考点四

同位语从句

同位语从句在句中作某一名词(advice, conclusion, doubt, fact, hope, idea, news, promise, question, suggestion, thought, truth, wish, word等)的同位语,一般位于该名词之后,说明该名词的具体内容。引导同位语从句的连接词主要有that, whether, why, who, where, how, when等。在同位语从句中,that和whether不作成分,that无词义,whether表示“是否”;if不能引导同位语从句。引导同位语从句的连接词一般都不能省略。

◆(2016·天津卷)The manager put forward a suggestion that we should have an assistant. There is too much

work to do. 经理提出一个建议,我们应该有个助手。有太多的工作要做。

that引导定语从句和同位语从句的区别:that引导定语从句时,that既起引导词的作用,又在从句中充当句子成分;如果在从句中作宾语that还可以省略,所修饰的名词指物时可用which替换。引导同位语从句时,that在从句中不充当任何句子成分,不能省略。

[对点演练]——单句语法填空

1.The question occurred to me where we should go to get the car repaired. We were in the middle of the forest at that time.

2.The fact has worried many scientists that the earth is becoming warmer and warmer these years. 两步突破名词性从句

第一步:识别名词性从句的种类

1.首先确定主句的谓语动词,确定主句的主谓结构。

2.分析从句在主句中所充当的成分,确定从句所属类型:主语从句、宾语从句、表语从句、同位语从句。

第二步:分析从句结构,确定从句引导词

确定从句的结构和意义是否完整,结合句意填写适当的连接词。

1.若从句结构完整,用从属连词:陈述事实用that;表示疑问“是否”用if或whether。 2.若从句缺少主语、宾语或表语,则考虑用连接代词。 3.若从句缺少状语,则用连接副词。

另外,还需注意一些特殊的引导词(如if, whether, because, as if等)的用法及that引导同位语从句与定语从句的区别。

1.(2019·浙江嘉兴模拟)Recently,a new research has suggested the possibility in a popular magazine pleasant smells might reduce pain.

that 解析:句意:最近,在一本流行杂志中,有一项新的研究表明好闻的气味有可能减少疼痛。设空处引导同位语从句,对possibility进行解释说明,且从句中不缺成分,意义完整,故填that。

2.(2019·江苏盐城中学段考)You should first explore your talents and get to know yourself so as to make a list of you think your real interest lies.

where 解析:句意:你应当首先开发你的天赋,了解你自己,以便列出一个你认为你真正的兴趣所在的单子。设空处引导宾语从句,作介词of的宾语,且在从句中作地点状语。

3.(2019·浙江五校联考)Through the process of comparison, it might be easier for us to understand important belief really is.

how 解析:句意:通过比较的过程,我们可能更容易理解信念是多么重要。设空处引导的从句作understand的宾语,且修饰形容词important,应用how引导该从句。

4.(2019·湖南株洲二中月考)With an optimistic attitude and a strong will, we can overcome difficulties we might meet with and achieve our goals.

whatever 解析:句意:拥有乐观的态度和强烈的愿望,我们能够克服可能遇到的任何困难,取得成

功。通过分析句子可知,overcome后为宾语从句,动词短语meet with后缺少宾语,再结合句意可知用whatever修饰名词difficulties,引导宾语从句。

5.(2019·河南中原名校联考)Earthquakes worry people a lot. The reason is we often do not know when they are coming. People can not prepare for it.

that 解析:句意:地震让人们很担忧。原因是我们通常不知道它们什么时候发生。人们没法做准备。设空处引导表语从句,从句的结构和意义完整,所以用that引导。

6.(2019·浙江杭州五校联考)The difficulty lies in they will come to our help immediately. whether 解析:句意:困难在于他们是否会马上来帮助我们。分析句子结构可知, they will come to our help immediately是介词in的宾语从句,根据句意可知,设空处表示“是否”,故用whether引导。

7.(2019·福建安溪模拟)They would appreciate it, to be frank, the goods could be delivered as soon as possible.

if 解析:句意:坦白地说,如果货物能够尽快被运送,他们将会非常感激。would appreciate it if...表示“如果……将不胜感激”,it作形式宾语,真正的宾语是if引导的从句。

8.(2019·河南漯河高级中学模拟) is expected to happen that small automated buses could make a difference when present human-operated transport has proved inefficient.

It 解析:句意:人们预测,当现有的人力交通运输系统被证明效率低下时,小型自动巴士可能会产生影响。根据句意以及句子结构可知,设空处为形式主语,真正的主语是that从句,故用It作形式主语。

9.(2019·河北石家庄一中一检)It turns out that looking attractive in photos isn’t easy due to the researchers are calling the “frozen face effect”.

what 解析:分析句子结构可知,介词to后面的宾语从句中are calling缺少直接宾语,故填what。 10.(2019·江苏苏州四市五区调研)It is obvious the local government can do to protect the environment for future generations.

what 解析:句意:为了子孙后代,当地政府在保护环境方面所能做的事情是显而易见的。It为形式主语, the local government can do to protect the environment for future generations是真正的主语,该主语从句缺少宾语,且表示物,故填what。
