以下是引用tania在2005-7-4 21:56:00的发言：

关于这题，我还有一个疑问。大全283：

Even though its per capita food supply hardly increased during two decades, stringent

rationing and planned distribution have allowed the People’s Republic of China to ensure

nutritional levels of 2,000 calories per person per day for its population.

(A) Even though its per capita food supply hardly increased during

(B) Even though its per capita food supply has hardly increased in

(C) Despite its per capita food supply hardly increasing over

(D) Despite there being hardly any increase in its per capita food supply during（B）

(E) Although there is hardly any increase in per capita food supply for

283题og 的解释说In choice A, the simple past tense hardly increased does not match the present perfect have allowed; consequently, it seems that two different time periods are being discussed.

那么76题如何解释呢？播出和观看应是同一时间啊，为何从句不用现在完成时？

76题, 若是live(实况转播), 确实播出和观看是同一时间, 问题就是不是所有的conference都是实况转播, 人们才会have seen a great deal of coverage. 即实况转播在先, have seen a great deal of coverage在后.

这个解释我不同意。因为如果只是先后关系，那应该是一般过去时＋过去完成时。如果用现在完成时来解释，太勉强了吧？

时态问题……有高人来解释下么？

我想有一个问题需要先澄清一下：不是任何时候主句使用了完成时，从句就必须使用完成时的，我想这一点大家都认同吧。我举个中文的例子，大家应该就可以体会出来为什么这里从句可以使用过去时了（当然用完成时也是可以的，只是代表另一个意思）：尽管世界杯足球赛在我国并没有全部直播，但是任有大量相关报道。直播可以是过去的事情，相关报道可以是由过去到现在任在进行的动作，所以这里使用过去时没有错。当然并不是说必须使用过去时，使用现在完成时也是可以的，但是表达了另外一个意思。望大家指正

ls可以看把OG重看一法, 只看tense, 會發現tense沒有這樣simple.
