—We all think ______ is careless ______ some scientists to say it is safe before doing any experiment.

A．that, for

B．it, for

C．it, of

D．that, of

Answer 1

C

試題分析：句意：-----你怎樣認為轉基因食品？-----我們都認為在沒有進行任何試驗之前科學家們說它很安全是他們的疏忽。這里是固定句式it be 形容詞+of sb to do,當形容詞可以描述某人的性格，品行時，用介詞of而不用介詞for，it在這里是形式主語，故選C。
