人教版初二英语上学期第一单元重点

Unit 1 How often do you exercise?

Section A

1a~1c

1.exercise 名词或动词

eg: Everyone should exercise once a day.

If we don't get more exercise ,we will get fat.

exercise作名词时，既可作可数名词，也可作不可数名词，当作“锻炼、运动”时，为不可数名词，当表示一系列有规律的运动时作可数名词，作“练习题”讲时，也可用作可数名词。

eg: We do morning exercise every day.

2.hardly 几乎不，几乎没有

eg:The twins hardly watch TV on weekdays.

Hardly形式上是由hard后加ly 构成，但并非hard的副词形式，hard 本身既可作形容词也可作副词，意为“努力地”

eg:My sister works hard.

3.ever 曾，曾经

ever作副词，常和现在完成时连用，用在疑问句、否定句、条件状语从句中，位于句中（助动词、be动词后，实意动词前）

eg:Have you ever been to beijing?

(1)ever用于肯定句中，意为“常常、总是”

eg：He is ever ready to help his friends.

(2)Ever 用于含有比较级或最高级的句子中，意为“在以往任何时候”

用来加强语气。eg:It is raining harder than ever.

(3)ever 用于特殊疑问句中，意为“究竟、到底”。

Eg:which ever do you want?

4.On weekends在周末，通常用于一般现在时中，一般指saturday、sunday,eg:I don't work on weekends.

5.I often go to the movies.我经常去看电影

go to the movies=go to the films/cinema

2a~2c

1.how often 意为“多久一次”用来提问事情发生的频率，常用every day ,usually,sometimes,often,never,等词或短语回答。

3.辨析sometimes,sometime,some times,some time

(1)sometimes意为有时，做频度副词，表示动作发生的不经常性，多用于现在或过去时态，在句中的位置比较灵活

eg:Sometimes I am late for school.

(2)Sometime是副词，表示在过去或将来的某个时候，指的是时间点，用语过去或将来时，对它的提问用when.

eg:—When will you come back? —Sometime later next month.

(3)Some times是名词短语，意为几次几倍，对它提问用how many times。

eg：He has been to Shanghai some times.

(4)Some time是名词短语，表示“一些时间、一段时间”，指时间段。eg:I will be away for some time.
