标题: 天山题目请教
5.    A    substance    from    the    licorice    plant,    50    times    sweeter    than    sucrose,    was    recently    discovered,        is    not    only    a    natural    sweetener    but    also    prevents    tooth    decay.
A)    A    substance    from    the    licorice    plant,    50    times    sweeter    than    sucrose,    was    recently    discovered
B)    A    substance,    which    was    recently    discovered,    from    the    licorice    plant,    50    times    sweeter    than    sucrose,
C)    A    substance    from    the    licorice    plant,    which    was    recently    discovered    to    be    50    times    sweeter    than    sucrose,
D)    A    substance    from    the    licorice    plant,    50    times    sweeter    than    sucrose    ,    which    was    recently    discovered,
E)    A    recently    discovered    substance,    50    times    sweeter    than    sucrose    from    the    licorice    plant,

答案是B，不是很理解。B中which    was    recently    discovered,    from    the    licorice    plant,    50    times    sweeter    than    sucrose,感觉很不爽。

我选了C，想请问：C中的which是否可以指代A    substance    呢？以前记得看过类似的例子，是可以的，请大家指点

         再来一题：

8.    Interest    rates    on    mortgages    have    declined    steadily    during    the    first    six    months    of    this    year    but    virtually    remained    unchanged    during    the    next    three    months.
A)    have    declined    steadily    during    the    first    six    months    of    this    year    but    virtually    remained    unchanged
B)    declined    steadily    during    the    first    six    months    of    this    year    but    virtually    remain    unchanged
C)    steadily    declined    during    the    first    six    months    of    this    year    but    remain    virtually    unchanged
D)    declined    steadily    during    the    first    six    months    of    this    but    have    remained    virtually    unchanging’
E)    declined    steadily    during    the    first    six    months    of    this    year    but    have    remained    virtually    unchanged

         答案是E，我觉得E中virtually修饰存在歧义，可修饰remained和unchanged，这个不如A好，在时态的角度考虑，为什么前面用过去时态，后面用完成时态？
我觉得declined    steadily    是一个过程，用完成时态好。请教大家

"from the licorice plant" 和 " 50 times sweeter than sucrose" 是对A substance 补充说明

C中的which有可能被误认为指代“the licorice plant”

不知道说清楚了没有，探讨中。。。

1 decline 已经结束，不应用现在完成时。

2 virtually remained：好像没有保持，和句意矛盾，
E中，virtually修饰unchanged，不是修饰remained。

时态上还是有点想不通，第8题为什么前面用过去，后面用完成？？

想不通...

作者: snow_mountain 时间: 2004-3-25 23:28
现在完成时态表示的是：过去某点开始，到现在的一个延续的动作。（这点不是绝对的，但延续性动作有此意。）此句后面的the next three months, 表明前面的first six months 的动作已经结束。

以下是引用bryony在2004-3-25 23:28:00的发言：

感谢bryony的解答，我有个疑惑：

first six months 的动作已经结束不能表示这个动作并非不是延续的动作，我觉得decline这个动作发生于过去，持续一段时间six months，而不是在过去一点发生的（过去时态），所以应该用完成时态

5. 我的大全里这一题的答案是C啊？

8.during可以接完成时吗？

这里把deline 理解成一个过程是可以的，问题是：A中前面用现在完成时态，表示延续动到现在的动作。后面却用过去时态，表示动作已经结束。而前面的时间又发生在后面的之前。逻辑上说不通呀。其实这题的关键在与：during 表示的时态是一个模糊的概念，不像since 铁定用完成态。关于during 我特别查过longman, 其中的例句说明during 加一段时间即可以跟完成态，也可以跟一般态。所以我认为这里把deline 理解成已结束的动作和延续动作都可以。如果没有后面半句限制，我个人也比较倾向用have done 的形式。

请问天山新题20-5#

Leaching, the recovery of copper from the drainage water of mines, as a method of the extraction of minerals, it was well established as early as the eighteenth century, but until about 25 years ago miners did not realize that bacteria taken an active part in the process.

(A) as a method of the extraction of minerals, it was well established

(B) as a method of the extraction of minerals well established

(D) was a well-established method of extracting mineral that was（C）

(E) had been a method of mineral extraction, well established

答案是C，我选了E，请问为何选C？

若选C，as early as修饰什么？
