例:Giant pandas, which inhabit restricted areas of high
A B
mountain bamboo forests, are rarely today and
C
when they are in captivity they breed poorly.
D
分析:错,应改为are rare。rarely为副词,不能作表语,故改为形容词rare
加宾语时名词和动名词的混用
后面加宾语当然要用动名词
例:Tilling means preparation the soil to plant the seeds
A B
and keeping the soil in the best condition to
C
help the crop grow until it is ready3 for harvesting.
D
分析:A错,应改为preparing。preparation为名词,后面不能接宾语,改为动名词preparing后既能接宾语,又与后面的keeping构成并列关系。
例:Langston Hughes, a prolific writer of the 1920‘s,
A
was concerned with the depicting the experience of
BC
urban Black people in the United States.
D
分析:C错,应改为depicting。 depicting在此为动名词,作介词宾语时不加冠词。注意此处还可以改为the depiction of,但略显累赘,因为后面还有of结构。The +动名词,这个动名词其实就变为了名词。
表示时间时,状语从句连接词和近义的介词混用
表示时间有两种可能,
一种是状语从句,由when and while引导,后面加句子
另一种是由介词引导,如during,后面加名词,
考试中往往就利用这个特点,总是给出相反的情况
例:Balloon observations for military intelligence
A B
were made while the American Civil War.
C D
分析:D错,应改为during。while是从属连词或并列连词,后面接句子,后面是名词短语时,应改为介词during。
