25.he must benear-sighted ______ he wears eye-glasses.
A)should
B)as
C)for
D)because
请问答案为什么选择c，请帮我详细的解答，谢谢~！

Answer 1

答案为 C for

because 是指直接原因，导致近视的直接原因可不是因为戴眼镜

for 在这里虽然在汉语中可以译为“因为”，从逻辑上来讲，它其实是表结果的，即 【因为近视，他才戴眼镜的】， 这种可以【倒因为果】的情况英语中只能用for.

再如：
He must have failed in the exam, for he is very sad.
比较：
He must have failed in the exam, because he is very lazy.
