标题: section 3/1 [打印本页] 作者: Energy 时间: 2003-12-29 17:37 标题: section 3/1 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) will begin at 9 a.m. and continue as long as the supply lasts will continue助动词不需要不出? D为什么不对，是and后面有逗号么 作者: rabbitbug 时间: 2003-12-29 20:53
D中的and后面的分句主语it不需要补出, 因为两个分句共享一个主语的时候, 后一个重述主语显得累赘.作者: Energy 时间: 2003-12-29 22:48
好像其他的题目没有省略助动词的，WILL DO, HAVE DONE，助动词可以省略吗在GMAT里作者: dreadpower 时间: 2003-12-29 22:59
不是很明白你的意思：“will continue助动词不需要补出?”

就是应该是will began and will continue啊作者: rabbitbug 时间: 2003-12-30 12:23
可以这样省略, 不过补出也没有错.
