2. 重点用法
1. 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。
2. be able to与can的意义相当，can没有将来时和完成时。
因此在shall, will, have等后面，要用be able to。
e.g. He is able to cook. = He can cook.
他会做饭。
I’ll be able to ride a bike.
我就要会骑自行车了。
注意：be able to与can不能重叠使用。
