问题补充:
单选题Thedutiesofapolicemanare_____than____.A.dangerouser ; a teacherB.more dangerous ; a teacherC.greater danger ; those of a teacherD.more dangerous ; those of a teacher
答案:
D解析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。)
