第四题选C,请问为什么?At the ___(3) of this century,as medcal knoeledge advanced,the span ___(4) to 45.In 1950,70-year-olds were ___(5) old.Today,a healyhy 70-year-old is looking forward to many more ___(6).3.A)edge B)age C)time D)turn4.A)enl
enlarge "扩大,放大", 是及物动词,直接跟宾语,不用加介词的,且词义与此空也不相符合, 因此排除AB;
increase 增加,增长,可作及物也可作不及物动词, 用在此空正合适.
再根据时间状语At the _turn__(3) of this century为过去时间,可判断此空要用过去时,
故第四题选C.
其它答案为: 3.D)turn 5. A)really 6. A)active
...
the span应该指的是寿命,应该用增加吧,指长度的增加,是一维的,enlarge只扩大,是一个范围,是二维的
