like与as的用法区别：
like说明相似关系，即二者在形态、性质上相似，但不等同。
e.g. He has done a lot of good things like Lei Feng.
他像雷锋一样做了许多好事。
as说明同一关系，指身份，意为“作为,当作”。
e.g. Don't treat me as a child.I'm 15. 别把我当小孩子了，我都十五岁了。
as 还有“像， 按照”的意思。
e . g .Please do it as I told you. 请照我的吩咐去做。
I have the same idea as you. 我和你想法一样。
1. ...and they can visit planets like Mars.
Language points
2. We will be able to do anything that can be done on the earth 我们将能做在地球上能做的任何事情。
1)be able to :能够做，适用于任何时态，与can ,could 比较，更侧重于客观上具备的能力。而且，can ,could 只用于一般现在和一般过去时。
例：He will be able to drive a car next year 明年他将会开车。
She is able to do the work alone 她能独自完成那项工作
I was able to swim at the age of seven 我七岁就会游泳了。
2)... that can be done on the earth. 是定语从句修饰anything。
从句的谓语用的是带有情态动词的被动语态，构成形式是“情态动词+ be +及物动词的过去分词”。
e.g. Trees can be planted in spring. 树可以在春季栽种。

3. What fun! 多么有趣啊！
这里fun为不可数名词， 有趣的事。
