249.Doctors still know little about how the Listeria bacterium is spread and why the disease it causes, listeriosis, afflicts some people in a contaminated area though it spares many others.
(A) though it spares
(B) where it spares
(C) despite sparing
(D) when sparing
(E) while sparing
key: E
想請教句中的 why the disease (it causes), listeriosis, afflicts some.....
這裡的listeriosis是什麼意思阿?是單純的插入語嗎?又為何要這樣使用呢?
基本上答案是可以接受的,但是實在不瞭解為什麼要加入這一個字,請大家幫幫忙!!!
PS:其實題庫裡已經有249一題了,但是裡面的題目和我的大全987中的249不一樣,所以另開一帖,請版主不要生氣喔
