大全 139

101.              As sales of cars and light trucks made in North America were declining 13.6 percent in late February, many analysts conclude that evidence of a recovering automotive market remains slight.

(A)  As sales of cars and light trucks made in North America were declining 13.6 percent in late February, many analysts conclude

(B)   Since sales of cars and light trucks made in North America declined 13.6 percent in late February, and many analysts conclude

(C)  With sales of cars and light trucks made in North America declining 13.6 percent in late February, with many analysts concluding

(D)  Because sales of cars and light trucks made in North America declined 13.6 percent in late February, many analysts concluded（D）

(E)   Because of sales of cars and light trucks made in North America declining 13.6 percent in late February, therefore, many analysts concluded

B.C.E自不必说, 可我对D中concluded 和后面 remains 的时态不一致不理解. 后面又不是一个客观真理或自然现象, 为什么要用一般时. 偶觉着conclude可以和前面的decline不同时, 但一定应该和后面的同啊. (尽管was declining 感觉不大好, 可还是觉得时态一致更重要)

请NN

    我也不是很明白为什么concluded 和后面 remains 的时态不一致，时态我一直很头疼

   请教NN

此题，我只知其一，不知其二。

1、只比较 A 和 D

2、有三个动词，分别位于三个部分：原因从句（decline），主句动词(conclude)+宾从动词(remain)；楼主所说的为保持一致，是没办法的实现的。因为这三项是无论如何不能全部用同一个时态。  55555555  ：（

3、A中decline用进行时，而主句谓语用现在时不太妥；

从语法上看：如果它用过去进行时，也就是过去的某一时间正在发生，那么主句谓语也应该是在那一个时点上；

从意思上看：过去进行时用来表达一种动作本身，而这里意思上更注重于decline的状态，所以，我支持用一般过去。

4、decline用了一般过去，conclude 也应该用一般过去，因为如果conclude用现在时，那么because从句应该用现在完成时，即has declined.

5、 concluded的宾从中remains，且不说用一般现在行不行，只问一句不用一般现在时，用什么呢？ 这里我觉得，remain这个动作本身具有一定的延续性使得其表现形式即时态的表达的特殊性。类似的动词，还有：continue

请其他NN讨论

我觉得是不是象conclude这种词当后面的从句表示一种结论的时候都会用一般时呢?

我的一个朋友指示：

叙述客观事实用一般现在时就可以了。e.g.  eople got to know that earth is round.
虽然这里是公理，但公理只是事实中的一种；非公理事实也可以用这个。
