Question

Sometimes our opinions differ _________ what we choose to observe and how we deal with what we’ve observed

A．which

B．since

C．because

D．because of

Answer 1

D

because 作為從屬連詞，主要用于引導(dǎo)原因狀語從句，既然是引導(dǎo)一個(gè)從句，也就是說它的后面不能再連用“引導(dǎo)詞”。句中的 what 相當(dāng)于 the thing that，也就是說 what you said 相當(dāng)于 the thing that you said。其中 the thing 用作 because of 的賓語，而that you said 為修飾 the thing 的定語從句。
