(D) A false hypothesis can have a scientistnow try to develop
(E) Hypotheses that are false can teach ascientist; they develop
ANSWER:
Q1: 这道语法题主要是很多同学不敢选B，认为B选项的failing表示同时发生，而根据逻辑语义又无法同时发生，所以failing是错误的，这里的failing表示的是伴随的一种状况。A选项有语法错误，C选项分号后应该是完整的句子，D选项和E选项的时态错误。
Q2: 这道题考察desirable和desirous的区别：desirous表示“渴望的”，其后加of，主语一般是人，表示某人对事物的渴望;desirable表示“值得得到的”，主语一般是物，或某件事。通过题意我们可以看出这里应该是desirable。
Q3: B. can have tried错误;C. wouldtry to错误;D. a false hypothesis做主语改变句子的逻辑意思，同时havesb do sth这个结构错误;E的they代表hypotheses，显然跟原文的意思相违背。

Q7. (RT0510_S06_Q29-W)
The cost of (A) safely disposing of thetoxic chemicals (B) is approximately (C) five times what the company paid (D)to purchase it. (E) No error
ANSWER:
Q5：这道题考察语法改错的一个原则，即不能改变句子原来的逻辑语义，原文的if和容易错选的C选项的逻辑语义是完全不同的，所以C是不正确的;其他选项都有语法错误。
Q6：考察语法常见的重复：imminent与happen inthe future是重复的，类似的考点还有: discovery& find; annual & every year; continue & go on等，最好不要在同一个句子中出现。
Q7：典型的语法错误--代词使用：这里面的代词指的是toxic chemicals，所以应该是them。
