语法手册上说，因为it指代了weight，所以B错，整个句子到底是个啥意思呢，。。。。it应该指代谁呢？

23. In a previous design, the weight of the discus used in
track competition is concentrated in a metal center,
but now it is lined with lead around the perimeter,
thereby improving stability in fl ight and resulting in
longer throws.
(A) In a previous design, the weight of the discus
used in track competition is concentrated in a
metal center, but now it is
（本句中it指discus的重量的重量，而it应该指discus，而不是discus的重量，因为只有discus能被lined with lead，discus的重量不可以。所以A错）
(B) According to a previous design, the weight of
the discus used in track competition was
concentrated in a metal center, but now it is
（同A）
(C) Once designed with its weight concentrated
in a metal center, the discus used in track
competition is now
(D) The discus used in track competition, once
designed with its weight concentrated in a metal
center, but now
（全句无谓语）
(E) The discus used in track competition was once
designed having its weight concentrated in a metal center and now.
（and前后不平行，而且表达也不太好）

弱弱的问一句，lined with lead around the perimeter 是什么意思呢？

zhaixuting · 发表于 2013-5-9 11:28:25

本题完全是在考逻辑意思感觉~~~~重量分布在中心，now重量分布在周围有什么不可以呢？？

zhaixuting · 发表于 2013-5-9 11:33:12

光就划线的前两小句，weigh 还是discus做主语我觉得都行，OG解释的 it grammatically refers to weight, which makes no sense.也有点扯。关键是看到thereby 后面两个Ving，动作发出者是逻辑主语，所以能判断出来weigh不是动作发出者，discus才能让其更stability。

拙见，请NN指教！

lined with lead 的意思就是在他的边上镶上lead （铅），知道这个意思马上可以排除A肯定是不对的答案

B - According to sth 这个用法错误，原本句子的语义是说在in a previous design, discus 怎么样，according
to 变成引用之前的design，而不是在之前的design里面，语义错误

D - 没有谓语动词

E - haivng 的语义表示having 后面的动作发生在主语动作之前，语义肯定不对

只有c 主谓一致line 的对象应该是 discus 而不是weight，正确
