初一 U19 Food and drink(1)
Ⅰ.首先用英语回答几个问题：
⒈What day is it today? 或者说：What day is today?
⒉What’s the date today?
⒊Who is on duty doday?
⒋Is everyone here today? 或者说：Are we (you) all here today?
⒌Who is not here today? 或者说：Who is not at school today?
参考答案
⒈It’s Monday today. 或者说：Today in Monday.
⒉It’s February 21,2000. (It’s February the twenty-first,2000)
⒊Wei Fang is an duty today.
⒋Yes, everyone is here today. / Yes, we are. 或No, we aren’t.
⒌Li Lei is not here today. / Li Lei is not at school today.
在问完以上这些问题之后再加上一个新的句子：I have a new watch, today?
给同学看：This is my new watch. Do you like it?
I have a new watch. Do you like it?是本单元的重点句型之一。
have是有的意思，但是它有人称的变化，请看下面人称与have的关系。
I have a new watch. 我有一块新表。We have some new books. 我们有一些新书。
They have two children. 他们有两个孩子。You have a god teacher. 你们有一位好老师。
以上的人称都可以have表示“有”。再请看下列各句：
She has a sister. 她有一个妹妹。He has a little dog.他有一只小狗。
Tom has a happy family. 汤姆有一个幸福的家庭。
以上例句的主语都属于第三人称单数形式，因此动词have就变了has.
Ⅱ. 本单元中出现了可数名词和不可数名词的用法，先请看下列单词：
rice(米饭，大米) tea(茶) bread(面包) milk(牛奶) meat(肉) water(水) orange(桔汁)
以上这些单词都是不可数名词，在英语当中，名词分两种：可数名词（单数形式、复数形式）、不可数名词（只有单数形式）。不可数名词虽然没有复数形式，但加上一个相应的量词就可以表示出多数了。
比如：a bowl of rice一碗米饭 a cup of tea一杯茶
two bowls of rice两碗米饭 three cups of tea三杯茶
a piece of bread一片面包 a bottle of milk一瓶牛奶
some pieces of bread几片面包 many bottles of milk许多瓶牛奶
a glass of water一杯水 a bottle of orange一瓶桔汁
two glasses of water两杯水 four bottles of orange四瓶桔汁
不可数名词表示多数时必须加上一个相应的量词，复数必须加在量词的后面，而不可数名词的后面永远不能加复数。除此之外不可数名词前面还经常用some（一些）和any（任何）两个词表示数量。
比如：I have some bread and a glass of milk. 我吃了一些面包和一杯牛奶。
但some多用于肯定句中，any用在否定和疑问句中，请比较下列各句。
⒈There are some bread on the table.
⒉Is there any water in the glass?
