请教SC大全 #866
866. Tiny quantities of more than thirty rare gases, most of them industrial by-products, threaten to warm the Earth’s atmosphere even more rapidly than carbon dioxide during the next fifty years.
(A) to warm the Earth’s atmosphere even more rapidly than carbon dioxide during the next fifty years
(B) to warm the Earth’s atmosphere even more rapidly over the next fifty years than carbon dioxide will
(C) during the next fifty years to warm the Earth’s atmosphere even more rapidly than carbon dioxide
(D) a warming of the Earth’s atmosphere during the next fifty years even more rapid than carbon dioxide’s
(E) a warming of the Earth’s atmosphere even more rapid than carbon dioxide’s will be over the next fifty years
答案选b，可是这里补出的是will原文给得失threaten，我个人觉得应该补出的是do吧。
所以我选了a，况且这里的over the next fifty year地用法感觉不太对，during the next fifty years才可以。
请问大家我的思路错在那里？
谢谢 |
