231 In the 1980's the rate of increase of the minority population of the United Stated was nearly (twice as fase as the 1970's)
b:twice as fast as it was in
c: twice what it was in
选c, b为什么不对？

236 Unlike other arachnids, which have their nerve cells evenly distributed along their (bodies,the scorpion's nerve cells are clustered in its head, like a mammal's.)
c:body,the scorpion has a cluster of nerve cells in its head, as a mamal does.
选c，可是为什么用their body 而不是their bodies?

怎么都没人理呢？

1。B错在fast是副词。

2。不解。完整的题目是什么？

２３１我可以解释：　
it 指的是80年的增长速度，不是指70的

后面一提有解释过，请翻翻看

236 主要考察的是unlike their body 应该是指each body

rate只能说高低，不能说快慢，increase反之。

sunder

exactly! 这个题就是考逻辑。

以下是引用jubel在2003-8-13的发言：
rate只能说高低，不能说快慢，increase反之。

rate 是一个数字，数字不能用快慢来形容，呵呵，这题我也错了，看了答案才反映过来。

后面一题，不是说选相对最好的答案嘛，unlike other arachnids,后面的主语要和other arachnids对称，一致。这个最重要啊。
