— Which is the deepest salt lake in the world? — The Caspian Sea is the deepest of all the salt lakes. — Did you know that China is one of the oldest countries in the world? — Yes, I did. It’s much older than the US.
2) 以e结尾的词，比较级＋r，最高级＋st 即可。 如： nice－nicer－nicest cute－cuter－cutest large－larger－largest 3) 以辅音字母＋y结尾的变y为i＋er或est 如: easy－easier－easiest
happy－happier－happiest 再如：early, busy, heavy, dirty, lazy也如此。
5) 多音节和部分双音节的词需要在形容词 原级前＋more构成比较级、＋the most构 成最高级。如：
beautiful － more beautiful － the most
beautiful 又如: delicious, popular, important, interesting, expensive, creative等 双音节的词如: careful － more careful － the most careful useful － more useful － the most useful
