【重点、难点点拨】
１．交际用语
（１）Welcome to our factory.
（２）Don't rush.
（３）Keep together, please.
（４）May I ask you some questions?
２．词组
（１）have been in/at 一直呆在……
（２）There has been 一直有
（３）ever since 自从
（４）walk through 走着穿过
（５）machine shop 金工车间
（６）come up steps 走上台阶

３．句型
（１）How long have you been in Beijing?
你在北京呆了多久?
How many times have you been to Beijing?
你去过北京几次?
这两句的关键在in与to的不同。in Beijing表示"在北京"，问呆了多长时间用How long; to Beijing表示"去北京"，问去了几次用How many times。
（２）for和since都可用在现在完成时，但它们并不相同。
〖for＋一段时间〗 〖since＋时间的起点〗
I've known her for three days. I've known her since Tuesday.
I've been here for a month. I've been here since July.
I've had my car for ages. I've had my car since １９９０.
（３）完成时态＋（ever）since＋动词一般过去时
例：He has worked here ever since it opened.
自从工厂创办以来，他就在这工作。
I have been worried since I lost my money.
Since 从句中的过去时，表示了从过去那件事发生以来，我一直如何如何。因此也可看作
是时间的起点。
（４）is about＋时间＋by…
例：Our school is about five minute by bus.
乘公共汽车去我们学校大约要５分钟。
My home is about twenty minutes by bike.
骑车去我家大约要２０分钟。
（５）瞬间动词如come, go, begin, die, leave的完成时态，不能与for和since连用。
例：The film has begun. （对）电影已经开演了。
The film has begun for ２０ minutes. （错）
The film has been on for ２０ minutes. （对）
电影已开演２０分钟了。
用"has been on"来表示电影开始的状态，这个状态可以持续。"has begun"瞬间动词、
不可持续２０分钟。
【重点、难点例题解析】
１．I haven't seen her since she school.
A．has left B．left C．leaves D．'ll leave
答案为B。当主句是现在完成时，since 从句中用过去时。
２．I have known Li Lei .
A．since three years B．for three years ago
C．since three years ago D．three years ago
答案为C。since＋时间起始点，而for＋时间段，且不能出现ago.
３．His grandma has for two years.
A．died B．dying C．die D．been dead
答案为D。句中有延续性时间，只能用表示状态的be dead的完成形式，既has been dead。
４．The teacher asked the boy to keep his eyes .
A．closed B．close C．closes D．closing
答案为A。keep＋宾语＋形容词，使某物或某人保持一种状态。close是动词，closed是过去分词可当形容词用。
