Special difficulties
好多动词后面既可以跟宾语从句，又可以和动词不定式to 搭配连用，其意义无差别。
打个比方：
Instead of saying: I find that he is quite unsuitable for the job.
We can say: I find him to be quite unsuitable for the job.
常见的动词如下：
believe, consider, find, declare, feel, know, suppose, think, presume, estimate, understand
e.g. I consider that he is the best candidate. = I consider him to be the best candidate.
e.g. We estimated that this picture is worth at least 500 pounds. = We estimated this picture to be worth at least 500 pounds.
