Consumers may not think of household cleaning products to be hazardous substances, but many of them can be harmful to health, especially if they are used improperly.

(A) Consumers may not think of household cleaning products to be

(B) Consumers may not think of household cleaning products being

(C) A consumer may not think of their household cleaning products being

(D) A consumer may not think of household cleaning products as（D）

(E) Household cleaning products may not be thought of, by consumers, as

但是many of them 指的是household cleaning啊，为什么前面句子的主语不将household cleaning前置，正如E？

并且在这道题里面，好像并没有限制是用a consumer还是consumers来作主语，只要是能跟句子本身的单复数对应好即可。

1） D

2） A consumer and consumers 确实在该题目中没有区别，这是我的“寻异求同”法例外的地方。这个地方没有办法寻异。

3）可以寻异的地方是 think of x to be/being OR think of xxx as y. 正确的介词是 AS。 这种小的搭配ETS最喜欢。

4）你的问题涉及到一致原则。我们一直考虑Gmat中句子要前后一致。但是XDF老师（本人没有上，在网上的笔记中看到）反复提到 （1）主动比被动牛，即主动优先。

同时我再加公认的一点（2） 不要随便对原有句子做大的改动，比如主动变被动，这是ETS大忌！

5） 关于think of as 联想扩展如下的内容：

consider…as… =think of …as…

1.consider vt. 认为；以为；考虑

consider sb./ sth. / adj./n. I consider him smart/ a smart guy.

sb./sth.+to be

sb./sth.+as /that clause

consider n/doing

how/when/…+to do sth

look upon/on…as

take…as…

regard…as…

treat…as…

He considered studying further in Australia. 他考虑过要去澳大利亚深造。

Have you considered how to solve this problem? 你们考虑过如何解决这个问题吗？

Abraham Lincoln is generally considered (to be/as) the greatest president of America.

6） consider 以及其类似的词要足够重视，仔细阅读 5）！
