32.A study commissioned by the Department of Agriculture showed that if calves exercise and associated with other calves, they will require less medication and gain weight quicker than do those raised in confinement. (C) associate with other calves, they required less medication and will gain weight quicker than do (D) associate with other calves, they have required less medication and will gain weight more quickly than do (E) associate with other calves, they require less medication and gain weight more quickly than 答案是E,没问题
我想问,选项C,D中的 required /have required 和will gain 单纯从时态上可以这样并列吗?? 是不是一定要现在时和现在时并列??
接我5楼的贴子 大全81题 81.Although fruit can no longer grow once it is picked, it continues for some time to respire, taking in oxygen and giving off carbon dioxide, similar to the way human beings breathe. (A) similar to the way human beings breathe (B) similarly to human beings who are breathing (C) just like the breathing of human beings (D) as human beings when breathing (E) just as human beings do when they breathe the answer:E。 这里的do代替taking in oxygen and giving off carbon dioxide?有点晕了,do可以指代这么多东西么?虽然我也选了e,但总觉得do指代有点不清,难道不会被误认为指代respire么? do的指代规则到底是怎么样的? 盼指点!!
Manhattan 上讲,"You can also omit units, verbs and even whole clauses from the second term,as long as there is no ambiguilty.也就是说,能否省略的标准很简单,省略之后,不会产生歧义,便可以省略。
在本句中。 I am taller than you (are),省略之后,也只能读出一个含义,那就是我比你高。
而在: I eat apple faster than you (do)这个结构中,若是省略助动词do,就有我吃苹果比吃你快的嫌疑。
因此最好就不要省略do .
