注意问题
1.在比较状语从句中经常省略某些部分,但比较对象的成分不能省.

例句:我的笔比你的多.

I drink more tea than he (does).

2.The new building is higher than the old one.
Those apples are bigger than these ones.比较级必须在同类中进行,即人与人比,物与物比,而且比较结构前后的词语要对称,特别注意在than或 as 之后不要漏掉可能出现的替代词 that ,those, one , ones.
3.如果主语是物主代词+名词,那么后面要用名词性物主代词。
His shirt is more expensive than mine.
4.Kate is more beautiful than Lily is.
She is five years older than I am.
I drink more tea than he does.
than前后句子的时态相同。通常用be动词,⑦情态动词can, may, must, could, should和助动词do, does ,did, will,have等来简答。
5.I have more pens than you (do).
many, much, little, few等词必须带名词

⑵某些单音节形容词,加more, most 构成比较级和最高级。
