十二、动词ing+名词的复数作主语结构这是一个比较难的结构,因为许多同学经常混淆动名词和现在分词。  现在分词相当于形容词,和后面的名词是修饰与被修饰的关系;  动名词是相当于具有动词特征的名词,和后面的名词是动宾关系。

那么如何在句子中判断动名词和现在分词呢?我们来看两个例子:  Doing exercises is a good habit. 做练习是一个好习惯。  The starring troops have to surrender.   第一个句子强调的是做,而不是练习,不能说练习是一个好习惯,只能说做练习是一个好习惯,因此do是中心词,它和后面的名词是动宾关系,那么这个do就是动名词;  第二个句子说挨饿的军队必须投降,是军队投降,而不是挨饿要投降,因此中心词是troop,starring是来修饰troop的,因此starring是现在分词。

在“动词ing+名词的复数”作主语结构的句子中,谓语动词是系动词is

例1:___by transferring the blame to others is often called scapegoating 1.    (A) Eliminate problems    (B) The eliminated problems(被消除的问题)   (C) Eliminating problems    (D) Problems are eliminated 分析:空格处缺主语。(A)不能作主语,(B)的名词为复数,与后面谓语动词相矛盾,(D)使句子出现两个谓语,故排除。(C)构成动名词短语,可作句中主语,故选(C)。这个题目的意思是通过把责任转嫁给别人,这种消除问题的方式,通常叫做替罪羊。

例2:___wooden buildings helps to protect them from damage due to weather.     (A) Painting     (B) Painted     (C) The paint     (D) By painting 分析:从谓语动词helps可判断出主语不可能为buildings, 因为主谓语在数上不一致,故空格处缺构成单数的词。四个选项中只有动名词painting符合这一条件,故选(A)。(B)构成复数名词短语,(C)无法与后面的名词连接,(D)构成介词短语,不能作主语,三个选项都可排除。 painted wooden buildings 被油漆的房子,中心词是buildings, 后面help不能用单数 painting wooden buildings油漆房子这件事情,中心词是painting

例3:Scientists think ___helps some tree to conserve 2 water in the winter.    (A) when losing leaves    (B) leaves are lost    (C) that losing leaves    (D) the leaves losing 分析:这道题目大家都能够选择C, 但是我们必须彻底理解C为什么正确,think that后面是宾语从句。losing是及物动词,丢弃叶子帮助树来保持水分,要注意不是树叶来帮助保持水分,而是丢弃树叶这个动作来保持水分。丢弃叶子是树主动丢弃,因此losing是动名词。

十三、make结构 make结构即为:make +sth.(宾语) +possible+(宾语补足语)共有三种形式:   make it possible+to do    make it possible+that引导的从句   make possible sth (这个sth一定很长,它后面有一个后置定语)

做题技巧:   如果possible后面有to do 或者that引导的定语从句, 中间一定有it    如果possible后面有名词,中间一定没有it

例1:X-rays are able to pass through objects and thus make___details that are otherwise impossible to observe .    (A) it visible    (B) visibly    (C) visible    (D) they are visible 分析:此题考动词make的一种用法,visible后面有名词,因此中间不能有it,选择C;可以看到空格后that引导的是定语从句,visible是宾语补足语,宾语补足语的存在是因为宾语太长了,details是宾语。

例2:Using many symbols makes___to put a large amount of information on a single map.    (A) possible    (B) it possible    (C) it is possible    (D) that possible 分析:从四个选项可以判断出本题考make的一种惯用法。首先排除明显的错误选项:C为句子,却没有与主句相连的连词,D中that后面应有主语并构成结构完整的从句。 由于后面是动词不定式,因此possible前面一定有it, it作形式宾语,故B正确。


v.使成为替罪羊( scapegoat的现在分词 )
  • Washington's scapegoating of China could take the world to the brink of a very slippery slope. 华盛顿方面找中国作替罪羊,可能会把世界推向灾难性下滑的边缘。 来自互联网
vt.保存,保护,节约,节省,守恒,不灭
  • He writes on both sides of the sheet to conserve paper.他在纸张的两面都写字以节省用纸。
  • Conserve your energy,you'll need it!保存你的精力,你会用得着的!
