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 flight 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

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

C.Once designed with its weight concentrated in a metal center, the discus used in track competition is now

D.This discus used in track competition, once designed with its weight concentrated in a metal center, but now

E.The discus used in track competition was once designed having its weight concentrated in a metal center and now

D选项的错误og解释是缺少main verb导致句子不完整。但是but后的line不是动词吗？but后面加句子缺少主语的话我还可以理解，求助大家~~

lined with
这里是被动,
所以没有谓语, 如果按你说的就变成主动, 不合理

还有一个问题，就是E.The discus used in track competition was once designed having its weight concentrated in a metal center and now 中having it weight concentrated做定语的用法正确么？OG中给出的关于E的解释是now后面缺少一个is...

我觉得previous放在句首再接一个now很别扭。。有人这么觉得吗

furthermore, I also think "according to XXX" should be followed by the content of XXX, and to attach another clause began with "but" seems illogical..

今天也做了这道题。。。错了。。。。

根据OG的解释，这句话的逻辑表达是discus之前和之后设计的不同：正确选项C的解释designed 是动词的过去时，和once 相呼应；而后半句now 和is 相呼应。D中，缺少现在时表达之后设计，
lined可以作为动词，但是会语义模糊；

还是SC推崇的简洁和准确

想问一下E里面的designed having its weight这个说法有错误吗

mastlight · 发表于 2010-6-15 15:16:58

看到别的地方的大牛写的:having的用法是错的，

design something to do something
be designed for somebody/something
be designed as something

接着问下used in track competition是修饰discus还是修饰the weight
