① 在含有连词than的比较级中，前后的比较对象必须是同一范畴，即同类事物之间的比较。
②在比较级前面使用much，表示程度程度“强得多”。
如：A watermelon is much bigger than an apple.
③ very, quite一般只能修饰原级，不能修饰比较级。

4. “the +比较级……, the+比较级”，表示“越……越……”。
The more money you make, the more you spend.
钱你赚得越多，花得越多。

③. A is …times larger /higher/longer/wider than B.
如：Our school is twice bigger than yours.

如：He is the tallest in our class.
他在我们班里是最高的。
