1.The human growth hormone, made by the pitulitary gland, is secreted (during sleep in higher concentrations than when awake.)
when sleeping in higher concentrations than waking hours
in higher concentrations during sleeping than waking
in higher concentrations during sleep than during waking hours
in higher concentrations when asleep than when awake
这道题选D，为什么其他选项不对，很迷惑.
2.这里还有一道题
Rembrandt so treasured his collection of Islamic portraits that when forced to sell them in order to raise monoy, (he first made copies of more than twenty.)
first he made copies of more than twenty
more than twenty were copied
copies of more than twenty were made
he copies more than twenty of them first
请问本题为什么选A？
没有具体指出是copy什么，A不会有歧异吗？E为什么不对？
3.be ware that 从句中应该用虚拟语气吗 ？即 sb. do sth?快要考试了，请大家帮忙解答一下好吗？
万分感谢！
during sleep in higher concentrations（ 语序不对）than when awake （when后接一个句子），这句是将growth hormone和when awake比较
during sleeping than waking，比较的是growth hormone和waking作者: Louisa_xy 时间: 2003-2-19 19:40
when forced to sell them in order to raise monoy,.....
这个when引导的状语从句决定后面主句的主语是he，除了A、E其他都不对，E的时态不对-copies，应该用过去时。

谢谢Louisa_xyMM及时的回答。偶第2题明白了，只是第一题没有明白MM的解释。
when asleep ,when awake 不合语法是因为when 后面只能接句子吗？after ，since，during 后面是不是就可以接名词？
during sleep than during waking hours我怎么感觉也不是很平行的呢？during sleep than during wake是不是更好呢？
很迷糊的问。作者: Louisa_xy 时间: 2003-2-19 20:34
wake不是“醒着的时候”的意思，waking hours是固定用法。
after, since 既可做conj.又可以做prep.后面可以跟句子也可以跟名词
during 只做prep.
when conj.& adv.后面不能只跟一个adj.作者: 新鲜 时间: 2003-2-19 20:58
呵呵，MM真是好强呀，PFPF
真心谢谢你！
3.be ware that 从句中应该用虚拟语气吗 ？即 sb. do sth?
ware是什么用法呢/
表示我偷懒，真的找不到适当的工具查
请MM好人做到底了，再次谢谢你。作者: Louisa_xy 时间: 2003-2-20 09:42
应该是be aware that...吧？
be aware that 后面不是必须用虚拟语气。作者: 新鲜 时间: 2003-2-20 20:38
Although many Whites, noting the presence of some Blacks in the middle class, think that the time for enforcing civil rights measures is past. Blacks generally are aware (that the figures for average income and unemployment show as wide of) a radical discrepancy as ever.
that average-income and unemployment figure show as wide
of figures for average income and unemployment showing as wide
本题的答案是B。如果aware后面接一般的从句，show应该加s呀。我用的是HIGH-GRE光盘，也不知道是不是题目有问题。作者: Louisa_xy 时间: 2003-2-21 12:41
