以prep1-81为例。In the major cities of industrializedcountries at the end of the nineteenth century, important public places such as theaters, restaurants,shops, and banks had installed electric lighting, but electricity
was in less than one percent of homes,where lighting was still provided mainly by candles or gas.
(A) electricity was in less than onepercent of homes, where lighting was still
(B) electricity was in less than onepercent of homes and lighting still
(C) there were less than one percent ofhomes with electricity, where lighting was still being
(D) there was less than one percent ofhomes that had electricity, having lighting that was still
(E) less than one percent of homes hadelectricity, where lighting had still been
考点: 句子结构(Grammatical Construction) 主谓一致(Agreement)
1) 两个句子并列,第一个句子含有be动词,第二个句子中的be动词必须省略,同时,一些重复的名词或形容词也必须省略,但是be功能不同时不能省略.
2) 单数复数: the percent of +可数名词复数形式, 谓语动词用复数 3) there be + n 句型中, be动词的单复形式由n的单复形式决定 4) 伴随状语不能修饰主句系动词
(A) 正确, 句子结构简洁; where就近修饰homes, 符合逻辑意思 (B) and lighting still provided省略了was, 因为这里was作为助动词,而前一个并列句的was是系动词,功能不同,不能省略. (C) where语法上就近修饰electricity,导致逻辑错误; being多余 (D) was应该改为were, 因为one percent of homes是复数名词; having…修饰对象不清楚。 (E) where语法上就近修饰electricity,导致逻辑意思错误;had been过去完成时态错误。 |
