二、语法填空

考点1提示词类填空

(一)词性转换

1.如果提示词在句中作定语(修饰名词)、作表语(跟在系动词后)或作宾补(表示宾语的性质状态),要用其形容词形式。注意区分以-ing和-ed结尾的形容词。

典例1 (2018课标全国Ⅰ)Running is cheap, easy and it’s always69 (energy).

解析设空处作表语,表示主语的特征,故填形容词energetic。

2.如果提示词在句中修饰动词或动词短语,修饰形容词或副词,或是修饰整个句子,要用其副词形式。

典例2 (2018课标全国Ⅱ)A taste for meat is63 (actual)behind the change: An important part of its corn is used to feed chickens, pigs, and cattle.

解析句意:对于肉类的喜爱实际上是这一变化背后的原因:中国的玉米有很重要的一个作用,就是

用来饲养鸡、猪和牛。本题考查副词。此处需用副词作状语,故用actual的副词形式actually。

3.如果提示词在句中作主语,在及物动词或介词(短语)后作宾语,前面有冠词、形容词性物主代词或名

词所有格修饰,要用其名词形式。

典例3 (2016课标全国Ⅲ)Some people think that the great Chi-nese scholar Confucius, who lived from roughly 551 to 479 B.C., influenced the 68 (develop) of chopsticks.

解析设空处之前有定冠词the修饰,其后有介词of,这里指“筷子的发展”,故填development。

实战演练（一）

1. This switch has decreased(pollute)in the country’s major lakes and reservoirs and made drinking water safer for people.

答案pollution句意:这种变化已经减少了中国主要湖泊和水库的污染,使人们的饮用水变得更安全了。本题考查名词。空格处作decreased的宾语,故使用pollute的名词形式pollution。

2.According to the World Bank, China ac-counts for about 30 percent of total (globe)fertilizer consump-tion.

答案global句意:根据世界银行的统计,中国占了全球化肥总消耗量的大约30%。本题考查形容词。空格处作fertilizer con-sumption的定语,故使用globe的形容词形式global。

3.I’m a (science)who studies animals such as apes and monkeys.

答案scientist句意:我是研究猿和猴子等动物的科学家。本题考查名词。设空处作表语,说明主语

的身份;根据提示词science可知填scientist。

4.The Central London Railway was one of the most (success) of these new lines, and was opened in 1900.

答案successful句意:伦敦中心地铁是这些线路中最成功的一条……。most后跟形容词组成形容词的最高级,所以答案填suc-cessful。

5....it must have been (fair) unpleasant for the passengers...

答案fairly句意:……对于顾客来说那一定是相当令人不愉快的……。此处用副词fairly修饰形容

词unpleasant。

6. It is (certain) fun but the lifestyle is a little unreal.

答案certainly分析句子结构可知,此处缺少副词成分修饰形容词 fun。故正确答案为 certainly。

7.(This development was only possible with the (introduce) of electric-powered engines and lifts.

答案introduction由空前的定冠词可知,此处需用名词形式,动词introduce去“e”加后缀-tion构成

名词形式。
