语法精讲
一. 选择疑问句
1.定义：选择疑问句是指说话人提出两种或两种以上可能的情况供对方选择的句式。选择项之间用or连接。
2.常见结构：
一般疑问句+or+选择项
特殊疑问句+选择项1+or+选择项2
3.注意：选择疑问句不能用Yes或No回答，一般需要在几个选择项中选择一个作答，也可以对所有备选项进行否定后，再视具体情况灵活作答。
二. 可数名词和不可数名词
可数名词：能以数目计算，可以分为个体的人或物。
单数可数名词常用不定冠词a/an, my, your, his等物主代词，two, three等数词或指示代词this, that来修饰。表示一类事物时，可用“a/an /the+单数名词”表示，也可用复数名词表示。
不可数名词：无法用数目来计算的名词叫不可数名词。
1.不能用不定冠词a/an，指示代词this, that, these, those或数词one, two, three等修饰，但可用定冠词the, my, your, his等物主代词，some, lots of / a lot of(许多)等来修饰。
2.不可数名词的量要借助“基数词+计量名词+of ”短语来表达，如three pieces of bread(三块面包), two glasses of milk(两杯牛奶)等。
3.作主语时，谓语动词要用单数形式。
4.用代词指代不可数名词时，用单数it,不用复数they或them。
既可作可数名词又可作不可数名词的词：
有一些词既可以充当可数名词又可以充当不可数名词，如chicken, fish, orange, cake, drink, fruit等。
这些词在不同的语境下可以灵活使用，如: fish指鱼肉时，是不可数名词；指鱼的种类时，是可数名词。orange指橙子时，是可数名词；指橙汁时，是不可数名词。
这类词是否可数需要根据具体的语境判断，这一用法在英语中非常常见，尤其是在描述食物、饮料或其他日常用品时。
