现在完成时
现在完成时（二）
1. 用法：
1) 表示发生在过去的动作，对现在造成的影响或
产生的结果，不与表示过去的时间状语连用。
I have cleaned the room.
（房间是我在过去打扫的，现在仍是干净的。）
2) 常与already，yet，never，ever，just等副词
连用。
① already意为“已经”，通常用于肯定句中，可
放在助动词之后，过去分词之前，也可以放在
句末。
I’ve already read this book.
② yet用在疑问句中，意为“已经”；用在否定句
中，意为“还”。yet常放在句末。
— Has he found his watch yet
— No, not yet.
③ just意为“刚刚”，表示动作刚刚发生，常放在
助动词与过去分词之间。
He has just come back from school.
④ ever意为“曾经”，用于疑问句或否定句中，
放在助动词与过去分词之间。
Have you ever been to Hong Kong
⑤ never意为“从来没有”，常与before连用。
I have never travelled by plane before.
3) 不能与表示过去的时间状语如yesterday, two
days ago等连用，但可以和表示从过去某一时刻
延续到现在（包括“现在”在内）的时间状语连
用， 如 today, before, this morning, these days,
so far, in recent years 等。
I have written two letters this morning.
2. 现在完成时与一般过去时的区别:
1) 现在完成时：表示过去发生的动作对现在造成了
影响或产生了结果，不与确定的表示过去的时间
状语连用。
Jill has bought a new computer.
（着重点是现在有了一台新电脑）
2) 一般过去时：表示过去某个时间发生的事情、存
在的状态或发生的动作。侧重点在于陈述一件过
去的事情，不强调对现在产生的影响。
He visited Guilin in 2008.
（只说明去桂林的时间）
3. have been to，have gone to和have been in的区别:
have been to
have gone to
have been in
去过（已回来）
去了（未回）
“待在”常常和
表示持续意义的
时间状语连用。

Around the world
Many European languages use the names of the heavenly bodies for the days of the week. For example, in English, Saturday is named after the planet Saturn, the sixth planet from the sun. Sunday is the day of the sun, a traditional day of rest. Monday gets its name from the moon and is the day of the moon.
