1、 As a result of the ground-breaking work of Barbara McClintock, many scientists now believe that all of the information encoded in 50,000 to 100,000 of the different genes found in a human cell are contained in merely three percent of the cell's DNA.
A.    50,000 to 100,000 of the different genes found in a human cell are contained in merely
B.    50,000 to 100,000 of the human cell's different genes are contained in a mere
C.    the 50,000 to 100,000 different genes found in human cells are contained in merely
D.    50,000 to 100,000 of human cells' different genes is contained in merely
E.    the 50,000 to 100,000 different genes found in a human cell is contained in a mere
答案是E。我的问题在于，E中出现了一个结构a mere three percent，我自己感觉这个说法好象很别扭，因为相当于说了a three percent。不知道这样的说法对吗？想请您解答一下，谢谢。

2. Certain pesticides can become ineffective if used repeatedly in the same place; one reason is suggested by the finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals.
A.    Certain pesticides can become ineffective if used repeatedly in the same place; one reason is suggested by the finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals.
B.    If used repeatedly in the same place, one reason that certain pesticides can become ineffective is suggested by the finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals.
C.    If used repeatedly in the same place, one reason certain pesticides can become ineffective is suggested by the finding that much larger populations of pesticide-degrading microbes are found in soils with a relatively long history of pesticide use than those that are free of such chemicals.
D.    The finding that there are much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are free of such chemicals is suggestive of one reason, if used repeatedly in the same place, certain pesticides can become ineffective.
E.    The finding of much larger populations of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in those that are free of such chemicals suggests one reason certain pesticides can become ineffective if used repeatedly in the same place.
In choice E, The finding of much larger populations .. . than in those that is an improperly constructed comparison.
这里的所谓an improperly constructed comparison是不是因为than前后都是短语、没有主谓？？换言之，是否than前后都应该是有主谓的句子，或者至少是有省略的句子。
3. From 1982 to 1987 sales of new small boats increased between five and ten percent annually.
A.    From 1982 to 1987 sales of new small boats increased between five and ten percent annually.
B.    Five to ten percent is the annual increase in sales of new small boats in the years 1982 to 1987.
C.    Sales of new small boats have increased annually five and ten percent in the years 1982 to 1987.
D.    Annually an increase of five to ten percent has occurred between 1982 and 1987 in the sales of new small boats.
E.    Occurring from 1982 to 1987 was an annual increase of five and ten percent in the sales of new small boats.
我的问题是，E如果改为Occurring from 1982 to 1987 was an annual increase of five to ten percent in the sales of new small boats.或者改为Occurring from 1982 to 1987 was an annual increase of five percent in the sales of new small boats.，不考虑逻辑是否成立，单纯从语法角度上来讲，这种表达在英语中是否成立，即这种倒装是否是英语语法允许的？谢谢。

E中出现了一个结构a mere three percent，我自己感觉这个说法好象很别扭，因为相当于说了a three percent。不知道这样的说法对吗？

a three percent的说法没错。但语气不一样。

你感觉这个说法：a just (only) three percent 也很别扭吗？ mere adv. 仅仅，只不过。

2 是否than前后都应该是有主谓的句子，后者至少是有省略的句子。

    我觉得有时补出，有时不补出谓语，也就是有时省略了，你说的有道理！但是一定要注意没有歧义！

以下是引用bob在2003-3-15 18:16:00的发言：

3. From 1982 to 1987 sales of new small boats increased between five and ten percent annually.
A. From 1982 to 1987 sales of new small boats increased between five and ten percent annually.
B. Five to ten percent is the annual increase in sales of new small boats in the years 1982 to 1987.
C. Sales of new small boats have increased annually five and ten percent in the years 1982 to 1987.
D. Annually an increase of five to ten percent has occurred between 1982 and 1987 in the sales of new small boats.
E. Occurring from 1982 to 1987 was an annual increase of five and ten percent in the sales of new small boats.
我的问题是，E如果改为Occurring from 1982 to 1987 was an annual increase of five to ten percent in the sales of new small boats.或者改为Occurring from 1982 to 1987 was an annual increase of five percent in the sales of new small boats.，不考虑逻辑是否成立，单纯从语法角度上来讲，这种表达在英语中是否成立，即这种倒装是否是英语语法允许的？谢谢。

我觉得这种表达很别扭，倒装我还没有看到这样的形式。个人意见，还望大家来指点~

lewis ,非常感谢。
LANLAN，非常感谢。第3题的那种倒装估计是不行的，呵呵，我瞎猜来着。
