知识梳理

辨析:just, already和yet
(1)just 用在现在完成时的肯定句中,表示“刚刚”。例如:
He has just had his meal.他刚吃完饭。
(2)already一般用在完成时态的肯定句中,可以放在句尾和句中。例如:
He has already gone home.他已经回家了。
already若用在疑问句中,常表示吃惊意外的语气,此时already常放在句末。例如:
Have you finished already 你已经完成了吗 (我以为你没有做完,表示出乎意料)

be up to sth.是固定短语,意为“正在做某事,忙于某事”。
What are you up to 等于What are you doing 例如:
What is he up to with all those books on the floor
这么多书放在地上,他在干什么呢
当我们说be up to sb.,则表示“由某人决定”。例如:
—Do you want to stay or go 你是留下来还是走呢

3.Astronauts have already been to the moon.
辨析:have(has) been in, have(has) been to和have(has) gone to
(1)have(has) been in 意为“已经在某地待了多长时间”,常与表示一段时间的状语连用。例如:
Mr. Brown has been in Shanghai for three days. 布朗先生来上海已经有三天了。
(2)have(has) been to意为“已经去过某地”,表示现在已经不在那里了。可与just, ever, never等连用。例如:
I've just been to the post office. 我刚才去邮局了。
(3)have(has) gone to 意为“已经去了某地”,表示到了某地或正在去某地的途中。总之,说话时该人不在现场,一般不用第一、第二人称代词作句子的主语。例如:
—Where is Tom 汤姆在哪里 —He has gone to the bookshop.他到书店去了。
做一做:单项选择。
1.—Have you ever____to Hangzhou —No, I haven't.

4.现在完成时
当表示动作已经完成,并对现在有一定影响时,我们用现在完成时。同时,可分别用just,already 或yet加以强调或说明。例如:
I have just heard the news.我刚听到消息。
Astronauts have already been to the moon.宇航员已经去过月球了。
可以看出,just用来表示“刚刚”,already用来表示“已经”,两者都用于肯定句中,一般置于have/has之后。在否定句中则可用yet,表示“还未”,有“以后可能会”的含义。例如:
The scientists have not heard from it yet.科学家还没有收到它发出的信息。
Man has not discovered any life in space yet.人类尚未在太空中发现生命。
