标题[请益] rate/effectiveness
时间Fri Mar 12 21:26:50 2010
1. The ___ of cloning is low, with an average of just over 1% of embryos
created by nuclear transfer producing live offspring in the scientific
literature.
(A)rate (B)effectiveness
Ans: (B)
【疑惑】请问(B)为什麽比(A)好呢? 我查到rate也是用low/high,而且也适用在犯罪率
等的,所以复制『率』不能吗? @@??
Thanks a lot!

1F:→ dunchee:你要看懂整个文意,不要只把注意力放在逗号前头的六个字 03/12 21:29
2F:→ dunchee:要讲"rate"的话,那麽後头讲的用特定方法"clone"出来的 03/12 21:31
3F:→ dunchee:embryos"都是clones",所以没有所谓的rate is low 03/12 21:31
4F:→ dunchee:"effectiveness"是用来指在用"复制手法"制造出来的embryos 03/12 21:32
5F:→ dunchee:里头有多少能存活下来(且成功的长成.. whatever they are) 03/12 21:33
6F:→ priv:其实科学文章里面rate通常指速率,所以不适合这里 03/12 23:28
7F:→ priv:如果rate前面加successful的话我觉得就可以 03/12 23:29
8F:→ priv:重点应该是rate有很多种rate,effectiveness比较明确 03/12 23:34
