Unit 2 Is your food and drink healthy?精品学案
导学重难点：
【可数与不可数名词】
不可数名词的基本概念 1、一般无法用数目来计算的名词叫做不可数名词. 2、不可数名词不能用不定冠词a/an或数词one修饰. 3、不可数名词如需用数量来修饰,需在前面搭配上合适的表示数量的词或短语. 二、具体表达方法 1、不可数名词的数量一般用some , much , a lot of , lots of , a bit of , a little , little等数量形容词表示. eg: some meat 一些肉 a lot of money很多钱 a little water 一点水 2、不可数名词的数量还可以用适当的量词（由普通名词充当）作单位来表示, 结构为“数词+量词（普通名词）+ of + 不可数名词”.其单复数变化就体现在普通名词上. eg: a piece of paper 一张纸 three pieces of paper 三张纸 3、可数名词的数量表示方法就是在可数名词前直接加数词,同时相应名词也要变为复数形式。
【祈使句】祈使句（Imperative Sentence）用于表达命令、请求、劝告、警告、禁止等的句子。祈使句记忆口诀：
祈使句无主语 ，主语you常省去；
动词原形当谓语，Don't句首变否定；
朗读应当用降调，句末常标感叹号。
【连词】连词（conj conjunction）是一种虚词， 它不能独立担任句子成分而只起连接词与词，短语与短语以及句与句的作用。
and（和，与;而且;于是，然后;因此）
but（但是；通常用not...but...不是...而是...；可是,然而；表示惊讶，不同意等--喔，哇；用来加强语句重复部分的语气--一定；用来引入新话题--那就；常用于否定句--而不，若不；用于含doubt,question等字的否定句中相当于that--对于），
or（或者，还是；用于否定句或问句--也不；否则，要不然；也就是说，换言之）
