下面是我整理的初一上册英语课本内容，新初一的同学不妨提前学习一下，新初二、初三的同学可以当做复习资料，供大家参考。
(1)this和that是指示代词，it是人称代词。
(2)距离说话人近的人或物用this,距离说话人远的人或物用that。
如：This is a flower.这是一朵花。(近处)
That is a tree.那是一棵树。(远处)
(3)放在一起的两样东西，先说this,后说that。
如：This is a pen. That is a pencil.这是一支钢笔。那是一支铅笔。
(4)向别人介绍某人时说This is…,不说That is…。
如：This is Helen. Helen, this is Tom.这是海伦。海伦，这是汤姆。
(5)This is不能缩写,而That is可以缩写。
如：This is a bike. That’s a car.这是一辆自行车。那是一辆轿车。
(6)打电话时，介绍自己用this,询问对方用that。
如：—Hello! Is that Miss Green?喂，是格林小姐吗？
—Yes, this is. Who’s that?是的，我是，你是谁？
注意：虽然汉语中使用“我”和“你”，但英语中打电话时绝不可以说：I am…, Are you…？/Who are you?
(7)在回答this或that作主语的疑问句时,要用it代替this或that。
如：①—Is this a notebook?这是笔记本吗？
—Yes, it is.是的，它是。
②—What’s that?那是什么？
—It’s a kite.是只风筝。
a和an都是不定冠词，表示一(个，支，本，块……)的意思，但不强调数量概念，而是强调类别，用来限定名词。a用在辅音音素开头的单数名词前，如：a pencil(一支铅笔)，a book(一本书)；an用在元音音素开头的名词前，如an eraser(一块橡皮)。如果名词前有修饰语，用a还是用an，则以该修饰语的第一音素决定用a还是用an。
英语中月份和星期名称都是专有名词，它们的首字母必须大写，并且前面无需用冠词。
用英语表示日期，其顺序为月+日+年，日和年之间需用逗号隔开。如：August 2nd，2003(2003年8月2日)。也可以用日+月+年来表示。如：10th May，2003(2003年5月10日)。英语日期前介词的使用：若指在哪一年或哪一月，则用介词in，若具体到某一天，则需用介词on。如：
①She was born in 1989
②She was born in August.
③She was born in August 1989.
④She was born on 2nd August, 1989.
this, that, these和those是指示代词，these是this的复数形式，指时间、距离较近的或下面要提到的人或事；those是that的复数形式，指时间、距离较远或前面已经提到过的人或事物。
①This is my bed. That is Lily’s bed.这是我的床。那是莉莉的床。
②These pictures are good.那些画很好。
③Are those apple trees?那些是苹果树吗？
在回答主语是these或those的疑问句时，通常用they代替these或those以避免重复。如：
④Are these/those your apples?这些(那些)是你的苹果吗？
Yes, they are.是的，他们是。
