Because an oversupply of computer chips has sent prices plunging, the manufacturer has announced that it will cut production by closing its factories for two days a month.
A.Because an oversupply of computer chips has sent prices plunging, B.Because of plunging prices for computer chips, which is due to an oversupply, C.Because computer chip prices have been sent plunging, which resulted from an oversupply, D.Due to plunging computer chip prices from an oversupply, E.Due to an oversupply, with the result that computer chip prices have been sent plunging,
选A
但是关于A中的时态我觉得有问题， 原文中用的是has sent。 但是后面没画线的地方用的是has announced。 sent prices 在 announce之前， 两个都是用现在完成时会造成顺序的混乱。has sent 不是应该改成had sent吗。 求解释。。作者: liuqiangde 时间: 2013-3-3 08:45
