四、例题解析
1) A错。应改为单数名词proportion,因前面有不定冠词“a”。
2) D错。改为lamp。
3) B错。应用单数名词star,因为前面有冠词“a”,尽管它被几个词所修饰,但仍要用单数。
4) C错。本句的主语是“a typical farm”,属于单数第三人称,而本句的谓语动词是cover(占地),所以应改为与主语相对应的动词形式covers。
5) A错。应改用is,因为主语为单数第三人称“the Petrified Forest”(石化林)。
6) A错。谓语是“is”,与之相呼应的须是单数名词或不可数名词,所以应将many改为much。
7) C错。根据上下文,supporter(支持者)应用复数supporters。
8) D错。应把foot(英尺)改为复数形式feet,因前面有数词thirty。
9) D错。应改为books,因前面有数词two,故名词应用复数形式。
10) A错。应改为复数名词years,因前面有数词100 million。
11) B错。six显然不能和单数名词element(元素)连用,故应将其改为sixth(第6个)。
12) D错。cities是复数名词,而前边的限定词为the seventh largest(第7个最大的),
