Question

13. Most of your errors in the paper are your carelessness but not your ability.

   A. due to   B. as a result

   C. since   D. because

Answer 1

13. A

13. A解析:句意:你试卷中的大多数错误都 是因为粗心而不是因为你的能力。

due to “由于;因为”，符合句意。

B项应该改为as

a result of (由于 ) ;since表示原因时接句子;because是连词，后面接句子，此处应

.改为 because of。
