以下是引用tiantian在2003-5-7 23:45:00的发言: LZM GMAT 语法改错精解
E4-18: One of every two businesses (fail) within two years. A. fail B. fails C.should fail D.may have failed E. has failed
答案B。为何不是E? 若将within two years 改为 in two years,答案可以是E吗?若改为 in the last two years 呢?我还是不太明白within 和 in 对时态影响的区别。
LZM的解释正确。here, no difference between in and within.
E4-17:Many writers of modern English have acquired careless habits that damage the clarity of their prose, but (these habits can be broken) if they are willing to take the necessary trouble.
A. but these habits can be broken B. but these habits are breakable C. but they can break their habits D. which can be broken E. except that can be broken
答案C。为什么A,B 不对?
AB. The reference is different between They and These.
