问题 选择题

The duties of a policeman are _____ than ____ .

A.dangerouser ; a teacher

B.more dangerous ; a teacher

C.greater danger ; those of a teacher

D.more dangerous ; those of a teacher

答案

答案:D

英语中由构词法派生出的形容词或副词比较级与最高级一律前面加more各the most构成。dangerous是由danger派生出的形容词,因此其比较级是more dangerous ; 在比较句中,一定要使比较的东西是一致的。为了避免重复,需比较的对象如果是单数,应该使用that of…代替,如果需比较的对象是复数,则用those of …,请看以下两个例句,并理解上述说法:The climate in Florida is as mild as in California . (佛罗里达州的气候与加州的气候一样暖和。) Classes in universities are more difficult than those in colleges . (大学本科的课程比大学专科的课程更难。)
