Apples are healthier than sweet cakes. 规则：出现 than 表两者对比时，形容词必须变为比较级，且 than 不能省略。 小练笔02 用所给单词的适当形式填空。 1．Judy is (careful) than her brother. 2．Mike is much (healthy) than his brother. 3．Grey crayon is (short) than Pink crayon. 4．Your feet are (small) than mine. 5．Running is (good) than staying at home. 6．The boy runs (fast) than the girl in the race. 应该做什么的句型高频易错点03 【课文原句】What should I eat first? 我应该先吃什么？ 【句型结构】疑问词 + should + 主语 + 动词原形 + 其他？ 【重点解析】 · should 是情态动词，含义 “应该”，用来给出建议、劝告。 · should 后面必须跟动词原形，不受主语人称、单复数影响，无变形。 · first 副词，意为 “首先，先”，放在句末修饰动作。 易错点提示 变问句时，should 直接提前，不需要加助动词 do/does What do you should do?
