以下是引用babydevil在2005-5-27 16:45:00的发言：

1.        The sale of government surplus machinery will begin at 9 a.m. and continue until the supply lasts.

(A) will begin at 9 a.m. and continue until the supply lasts

(B) begins at 9 a.m., continuing until the supply lasts

(C) will begin at 9 a.m. and, until the supply lasts, will continue

(D) begins at 9 a.m. and, as long as the supply may last, it continues（E）

(E) will begin at 9 a.m. and continue as long as the supply lasts

请问为什么答案是E不是D?E中时态并不一致，will begin ... and continue as long as ...lasts

先用将来时will begin..., and (will) continue;最后用一般现在时lasts,而D的时态一致，都是一般现在时

感觉D更好一点

D 去掉插入语就是：

The sale of government surplus machinery begins at 9 a.m. and it continues.

在此处的代词使用不够简洁。

E十分并列，而且表达清楚简练。

做对了，但是还有疑问，顶

那

1.
            The sale of government surplus machinery will begin at 9 a.m. and continue until the supply lasts.

(A) will begin at 9 a.m. and continue until the supply lasts

A选项不是很完美吗？

大全给的解释是until应该加一点时间，但是有例句：

You cannot leave until your work is finished.

We can't start the job until we have the approval from the authority concerned.

NN来解释下啊！！

怎么没有解释啊/？

這題還有幾個問題需要高手來幫個忙

1.will的去除是否有改變句義？

2.B選項錯誤在於改變主從關係嗎？？
可是continuing做伴隨伴隨狀語不通嗎？？

3.A和E 為何E比較好？？
