1My old school was small, but my new school is much bigger. My old classroom was smaller, too. The library here is brighter and more beautiful than the old one. At first, I was nervous because my old school was like a small family, and I knew everyone by name. I studied there for five happy years.
2But my new classmates are as friendly as my old friends. They showed me around and taught me the school song. Ken runs faster than anyone else in our class, so he is the best runner in the school team. I am better at maths now because my new teacher explains things clearly. The food in the new canteen is tastier than before.
3My little sister thinks our new flat is more comfortable than the old one, but she still misses our old neighbours. Change is not always easy, but things can get better and better. I know my new school is busier than my old one, so I try to speak more English every day. Last week, I even made two new friends. I believe my new school life will be the best.

3逐步讲解 Steps
- 短短形容词（一个音节）在字尾加 er 构成比较级：tall 变 taller，old 变 older。例句：Tom is taller than Peter. 提示：重读闭音节、单一辅音字母收尾的字要双写，如 big 变 bigger，hot 变 hotter。
- 长长形容词（两个或以上音节）在前面加 more 构成比较级：more beautiful、more expensive。例句：This bag is more expensive than that one. 提示：more 之后仍用形容词原形，不可说 more beautifuller。
- 不规则不规则比较级要逐个牢记：good 变 better，bad 变 worse，far 变 farther。例句：His marks are better than mine. 提示：这几个词出现频率极高，宜制成字卡，每天背几个，考试时便能直接反应。
- 结构比较句的基本结构是 A is 比较级 than B。例句：My new school is bigger than my old school. 提示：than 之后的比较对象要与前面的主词对称，学校要与学校比，人物要与人物比，同类才能比较。
- 不规则比较级数量与程度的比较级也有不规则变化：many 与 much 变 more，little 变 less。例句：I have more books than my brother. 提示：more 可修饰可数与不可数名词，less 只修饰不可数名词，例如 less water。
- as... as 同级比较表示程度相同用 as 加形容词再加 as。例句：My new school is as big as the old one. 提示：否定式 not as... as 表示不及，例如 My bag is not as heavy as yours；中间必须用形容词原形，不可用比较级。
