举例
Unit2 How often do you exercise?
词语辨析：
1. how often 多久一次，用来提问动作发生的频率。回答用：once，twice, three times 等词语。
How often do you play sports? Three times a week.
how long 多长，用来询问多长时间，也可询问某物有多长。
How long does it take to get to Shanghai from here? How long is the ruler?
how for 多远， 用来询问距离，指路程的远近。 How far is it from here to the park? It’s about 2 kilometers.
1. free 空闲的，有空的， 反义词为 busy. be free 有空，闲着，相当于 have time.
I’ll be free next week. = I’ll have time next week.
还可作“免费的、自由的”解。be free to do sth. 自由地做某事。
The tickets are free. You’re free to go or to stay.
2. How come？ 怎么会？ 怎么回事？表示某件事情很奇怪，有点想不通；可单独使用，也可引导一个问句， 相当于疑问句 why, 但 how come 开头的特殊疑问句使用的仍然是陈述语序。
How come Tom didn’t come to the party? = Why didn’t Tom come to the party?
3. stay up late 指“熬夜到很晚，迟睡”。 Don’t stay up late next time.
stay up 指“熬夜，不睡觉”。 He stayed up all night to write his story.
4. go to bed 强调“上床睡觉”的动作及过程，但人不一定睡着。I went to bed at eleven last night.
go to sleep 强调“入睡，睡着，进入梦乡”。 She was so tired that she went to sleep soon.
5. find + 宾语 +名词, 发现 ： We have found him (to be) a good boy.
find + 宾语 + 形容词， 发现： He found the room dirty.
find + 宾语 + 现在分词， 发现 ： I found her standing at the door.
6. percent 百分数， 基数词 + percent： percent 没有复数形式，作主语时，根据所修饰的名词来判断谓语的单复数。 Forty percent of the students in our class are girls. Thirty percent of time passed.
7. more than 超过，多于，不仅仅， 相当于 over. 在句型转换中考查两者的同义替换。反义词组为：less than. I lived in Shanghai for more than / over ten years.
9. afraid 形容词， 担心的，害怕的，在句中作表语，不用在名词前作定语。
I’m afraid we can’t come here on time.
be afraid of sb / sth 害怕某人 / 某事； be afraid of doing sth. 害怕做某事。
Some children are afraid of the dark. Don’t be afraid of asking question.
I’m afraid + 从句， 恐怕， 担心： I’m afraid I have to go now.
be afraid to do sth 害怕做某事
10. sometimes , sometime, some times , some time 的区别：
sometimes 频度副词， 有时。表示动作发生的不经常性，多与一般现在时连用，可位于句首、句中或句末。
Sometimes I get up very early. ------How often do you get up?
sometime 副词，某个时候。 表示不确切或不具体的时间，常用于过去时或将来时，对它用疑问词when.
I will go to Shanghai sometime next week. ------When will you go to Shanghai next week?
some times 名词词组， 几次，几倍。其中time 是可数名词，对它提问用how many times.
I have read the story some times. -------How many times have you read the story?
some time 名词短语， 一段时间. 表示“一段时间”时，句中谓语动词常为延续性动词，提问时用 How long.
I ‘ll stay here for some time. -----How long will you stay here?
