七年级英语上册Unit 2 Grammar 同步练
讲解一
She dances for half an hour every day. 她每天跳半小时的舞。
“for+一段时间”表示某一动作或状态持续了一段时间,故与其连用的谓语动词也要是延续性的。对“for+一段时间”提问时用 how long“多长时间”。如:
We need to sleep for eight hours every day. 我们每天需要8个小时的睡眠。
—How long do you study English? 你学英语多长时间了?
—I study English for ten years. 我学英语10年了。
拓展
“介词in+一段时间”表示“(从现在算起的)一段时间之后”,多用于一般将来时态。如:
He will be back in two hours. 他将在两个小时后回来。
