一、写出下列形容词或副词的比较级

old - older, young - younger, tall - taller, long - longer
short - shorter, strong - stronger, big - bigger, small - smaller
fat - fatter, thin - thinner, heavy - heavier, light - lighter
nice - nicer, good - better, beautiful - more beautiful,
low - lower, high - higher, slow - slower, fast - faster,
late - later, early - earlier, far - farther/further, well - better

1. older
2. fatter
3. younger
4. thinner
5. bigger
6. higher
7. better
8. bigger
9. heavier
10. earlier
11. slow, slower

楼上除了最后一道错了，其他都正确。
可惜没弄清 修饰动词要用副词 即修饰run要用slowly,不能用slow
所以最后一道应该是：slowly, more slowly
