請教1下關於比較結構的省略的問題。不是很清楚什麽時候比較從句的主語， verb ,情態詞， 助動詞省略的規則。
有時候用do ， 有時候又省略。。。。很不了解。
hoping someone can help clarify this part....thanks a lot !!!!!!
In its most recent approach, the comet cormmeelin passed the earth at about the same distance and in about tthe same position, some 25 degrees above the horizon , that Halley's comet will pass the next time it appears.

c.as Hally's comet
d. as will Halley's commet
e. as Halley's comet will do
answer is d ...
but in this question , the main sentence does not have any 情态动词或者助动词. I think the answer E is not wrong, but it says that Do has to be omitted.... please explain why?
thanks a lot ...

honeybebe，这是我的疏忽，因为LZMM问什么时候省略这些东东，我也没仔细看题。刚巧做题的时候碰到这题了，这道题跟省略还不是一回事叫我感觉，毕竟后面明确给出时间标志，the next time it appears，明确指出了时态应当采用将来时，而将来时的标志助动词当然就是will了，这里必须用的，至于相同的动词pass在这里的确是多余了，所以必须省略，就算用do也不成，因为从语法的角度上将不是不对，而是多余。
ok ....謝謝了。那你的意識是說主句的謂語動詞跟從句的動詞相同時，可以省略以免重復？

B很完美，while at the same time introducing some 100,000 dangerous chemical pollutants that have，while带状语从句省略形式，并且后面的have用定语从句限定先行词为pollutants，A的问题在于后面的having，-ing形式在此有两种可能，一种做定语修饰pollutants，这是我们所需要的，但是还有一种可能就是做improve的状语，形式主语为Industrialization and modern methods of insect control，造成歧义，所以A还是不行。
