用于两者（人或物）之间，表示“其中一个比另一个更……”或“较……”，后面通常用连词than 连结另一个比较的对象，其基本句型是：
主语＋谓语（系动词）＋形容词比较级＋than＋对比对象。

early—earlier, busy—busier, easy—easier, heavy—heavier,
dry —drier, sunny—sunnier, happy—happier.
5. 多音节词或部分双音节词变比较级时，在前面加more:
friendly — more friendly, careful—more careful, outgoing— more outgoing
interesting— more interesting, difficult—more difficult
6. 部分双音节词的比较级有两种变化方式：

（二）不规则变化
good /well —better, bad/ill—worse, many/much—more,
old—older/elder, far—farther/further, little—less

ex: 1. The room is very big.
2. The person is quite clever.

4. He eats too much, so he's much too heavy.
5. I'm a little hungry, I'd like something to eat.
