(Consumers may not think of household cleaning products to be )hazardous substances but many of them can be harful to health, espcially 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 household cleaning products as
A.think of ..as 的用法是对的,但我觉得c用a consumer句意好像不太对,泛指consumer,应用consumers,而不应用a consumer。a中,think of 的用法不对,一般用think ...to be,think of ...as,但b的用法为什麽对呢,是think sth sth吗,谁给解释一下。[em27]
