Scientists have sent spaceship to Mars. The journey has taken several months.
Review
Astronauts have already been to the moon.
No one has been to Mars yet, because Mars is very far away, much farther than the moon.
Scientists have also discovered many other galaxies in the universe.
Scientists have sent spaceship to the planet Mars to take photos. They have even sent spaceships to travel outside the solar system.
No spaceship has travelled far enough to reach other stars in our Galaxy.
1. I’ve just made a model spaceship.
2. Has it arrived yet
3. Astronauts have already been to the moon.
4. We have not found life on any other planets yet.
在现在完成时的句子中，already(已经)、just(刚刚)常用于肯定句，放在have和has的后面。yet(还、尚、仍然)常用于否定句和疑问句，（放在have和has的后面也可放在句末）。

have/has been to与have/has gone to的区别:
have/has been to表示某人“去过某地，现在已经回来了”。
have/has gone to表示某人“去某地了”，这个人已经不在这里了。

It has gone there, but it has not come back yet.
Astronauts have been to the moon. They went there and then they came back.
Look at these sentences.
1. Astronauts have been / gone to the
moon and returned.

space. It will travel for ten days.
3. The astronaut has been / gone to the
space station. He will come back

现在完成时(2)
当表示动作已经完成，并对现在有一定影响时，我们一般用现在完成时。同时，可分用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。
He has just started to explore other planets. 我们才刚刚开始探索其他行星。
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，一般是置于have / has 之后。在否定句中则可用yet, 表示“还未”， 有“以后可以会”的含义。例如：
The scientists have not heard from it yet. Man has not discovered any life in space yet. 另外，在使用现在完成时的时候，要注意与一般过去时的区别。现在完成时在表达经历时只表示该事件是在现在之前的某一个时间里发生的，重点在于已完成动作对现在的影响。
而一般过去时则表示在过去某一具体时间发生的事情。例如：
I have just been to London. I went there last month.我刚去过伦敦，上个月去的。
I have already finished my homework. I finished it an hour ago. 我已经完成家庭作业了，一小时前完成的。
在没有明确的过去时间状语时，如何判断该用现在完成时还是该用过去时呢？判断的标准是看该行为是否对现在有影响，也就是说该句强调的是什么。试看以下对话：
A: Where have you put my book I can’t find it. 你把我的书放哪儿去了？我找不到。
B: I put it on your desk yesterday.
我昨天放你桌子上了。
该对话中，当A 问对方把自己的书放在何处时，A 感兴趣的是现在的状态，因此用现在完成时。但是B 回答时只是说明当时放的位置，所以用一般过去时。再看下面的对话：
A: Would you like to go and see the film with me tonight 你今晚想和我去看电影吗？
B: Sorry, I have seen it already. 不好意思，我已经看过那部电影了。
对话中的现在完成时表示对结果的强调：“电影看过了，所以不想再看了。
