Module 3 Journey to space
现在完成时(二)
1．I've just made a model spaceship.
我刚刚制作了一个宇宙飞船模型。

2．Has it arrived yet?
它已经到达了吗？
3．Astronauts have already been to the moon.
宇航员已经去过月球。

4．There has been life on the earth for hundreds of millions of years.
地球上有生命已有数亿年了。

5．We have not found life on any other planets yet.
我们还没在任何其他行星上发现生命。

.
1．现在完成时态还可以用来表示“刚刚做完某事；已经做完某事”等，此时经常用just, already和yet来表示，其中，just表示“刚刚”；already表示“已经”，一般置于have/has 之后；just和 already 都用在肯定句中，在否定句和疑问句中则可用yet，表示“还未”。

例如：
I have just heard the news.
我刚刚听到消息。

Astronauts have already been to the moon.
宇航员已经去过月球了。

I haven't been to Beijing yet.
我还没有去过。

注意： just, already和yet在句中的位置：
I have just heard from my son.
我刚刚收到儿子的来信。

I've already bought the book.
我已经买了这本书。

He hasn't cleaned the house yet.
他还没有打扫屋子。

2．在现在完成时态中，要注意have been to和have gone to的区别，前者表示“去过某地”，但现在已经回来了；后者表示“去了某地”，现在还没回来。

例如：
I have been to MountTai twice.
我去过泰山两次了。

He has gone to Beijing. He won't return until next Wednesday.
他去了，直到下周三才回来。
