【问】
用for或because填空:
- He was absent, ____ he was ill.
- He was absent ____ he was ill.
- ____ he was ill, he was absent.
答案:1. for;2. because;3. Because
问题:for与because都是“因为”,为什么不能换用?
【答】
for和because虽然都是“因为”,但不可换用,区别在于:
for是并列连词,要用在句子中间,连接前后两个分句,构成并列句,且for前须有逗号,这是for用作并列连词最直观的特点。此外,for做并列连词不用在句首,因为那样起不到“并列”的作用。
because是从句的引导词,引导原因状语从句。状语从句在主句前面时用逗号和主句隔开,在主句后面时通常不加逗号,这是各种状语从句的常态。
