Unit 1 Our school subjects
1. Nice to see you.和Nice to meet you. 见到你很高兴。但用法上有区别。Nice to meet you.用于初次见面时打招呼,应答也是Nice to meet you.而Nice to see you.用于两个认识的人见面打招呼,应答也是Nice to see you.
2. subject 和lesson的区别
subject 是指学科,课程。而lesson指的是具体的一节课。它们的区别还在于lesson可接在具体科目名称后面,如 a Maths lesson一节数学课 an English lesson一节英语课。而subject一般不与科目名称一起出现。
3.学科类的单词第一个字母要大写,如English, Chinese, Maths, Art, PE, Music, Science等。还有一些其他的用法如:He’s an English boy. 他是一个英国男孩。We’re Chinese. 我们是中国人。I like listening to music.我喜欢听音乐。
4. It’s time fo r...... 到干什么的时间了。后面跟名词。
It’s time for sth. = It’s time to do sth. 意思都是干什么的时间了,但是用法上有区别。It’s time for +名词= It’s time to+动词如:It’s time for PE=It’s time to have a PE lesson. It’s time for class.=It’s time to have class.
