（一）重点单词
［单词学习］
◎exercise
【用法】作动词，意为“运动，锻炼”；作名词，意为“体育锻炼，运动”时，是不可数名词；意为“练习，操”时，是可数名词。

【例句】1. He exercises three times a week.
2. Walking is good exercise.
3. We do morning exercises every morning.
【考查点】在句子中是用作动词还是名词
【易错点】作名词时对其可数与不可数的判断
【考题链接】
1. He is very strong because he often e .（根据句意及首字母完成单词）
答案：exercises
解题思路：exercise作动词时意为“运动，锻炼”。

在这个句子中缺少的是谓语动词，主语是表示第三人称单数的he，所以用动词的第三人称单数形式，因此填exercises。

2. It’s good for us to do every day.
A. eye exercise
B. eye exercises
C. eyes exercise
D. eyes exercises
答案：B
解题思路：exercise作“体操，运动”讲时常为exercises，选项A、C被排除，在英语中用名词修饰名词时，前边的名词须用单数形式，故选B。

◎maybe
【用法】作副词，意为“很可能，大概”，相当于perhaps，常用于句首作状语。

【例句】1. Maybe you are right.
2. Maybe he will come this afternoon.
【考查点】maybe 与may be 的区别
在may be中，may是情态动词，be是动词原形，两者构成完整的谓语形式，与主语形成系表结构，意为“也许是、可能是”。

【例句】1. I can’t find my watch. It may be in your pocket.
2. He may be a soldier.
【易错点】分不清是副词还是情态动词
【考题链接】
This woman his mother.
A. maybe
B. may be
C. may is
D. perhaps
答案：B
解题思路：maybe，perhaps意为“也许”，用作状语，本句缺少谓语，可排除A、D项；may意为“可能”，情态动词后需接动词原形，所以may is错误。

故选B。

句意为：这个女人也许是他的母亲。

◎health与healthy
【用法】health是一个不可数名词，意思是“健康（状况）”，常用于短语be in good (poor, bad) health表示“身体好（不好）”，keep in good health表示“保持身体健康”。

healthy是health的形容词形式，意为“健康的”，是由名词health + y构成的形容词。

常与keep构成短语keep healthy，意思是“保持健康”。

healthy的反义词是unhealthy。

【例句】1. He often comes home to see his mother, because she is in bad health.
2. Eating too much junk food is an unhealthy habit.
【考查点】在具体的语境中选用名词或形容词形式
【易错点】名词与形容词混淆不清
【考题链接】
1. You shouldn’t smoke. It’s bad for your .
A. health
B. healthy
C. healths
D. healthies
答案：A
解题思路：health意为“健康”，是不可数名词，无复数形式，故C项为错误答案；而healthy是形容词，经常作表语或定语；D项healthies不存在，由句意“你不应该吸烟，它有害于你的健康。

”可知本题正确答案为A。

2. Good eating habits help you keep healthy. (同义句转换)
Good eating habits help you .
答案：keep in good health
解题思路：keep healthy 意为“保持身体健康”，同义词组为keep in good health，但要注意两个词组中healthy和health的不同。

所以填写keep in good health。

◎same与different
【用法】same指“相同的”，前面通常要有一个定冠词the，常构成短语the same as“与……一样”；different译为“不同的”，其后的可数名词应为复数形式，常构成短语be different from“与……不同”。

different 的名词是difference，是一个可数名词。

【例句】1. We are in the same class.
2. His new bike is the same as mine.
3. We are in different classes.
4. This book is different from that one.
5. There are many differences between Chinese and English.
【考查点】the same as与be different from的固定搭配；名词difference的使用
【易错点】different与difference混淆不清
【考题链接】
1. 我的想法和你的一样。

My idea is yours. （完成句子）
答案：the same as
解题思路：the same as…意为“与……一样”，as后可接名词、代词或名词性物主代词。

2. There are many (different) between the two books. （用所给词的正确形式填空）
答案：differences
解题思路：differences 句意为：两本书之间存在许多差别。

many修饰可数名词的复数，因此要将different变为名词difference且加“s”。

［即学即练］
1. Jim never (exercise). It’s bad for him.
2. My grandfather takes some exe rcise every morning. （写出同义句）
My grandfather every morning.
3. he is a farmer.
A. Maybe
B. May be
C. May
4. I look after my and I am (health).
5. The way we learn English is quite different that we learn maths.
A. from
B. off
C. between
D. with
6. Most of my classmates don’t like to talk with their parents, but I am them. I love to talk with my parents.
A. the same as
B. different from
C. interested in
D. angry with
（二）重点短语
［短语学习］
◎be good for
【用法】be good for意为“对……有好处，对……有益”，后接表示人或事物的名词。

它的反义短语为be bad for，意为“对……有害处”。

【例句】1. Reading books is good for you.
2. Vegetables are good for us.
3. Eating too much is bad for your health.
【考查点】be good for与be good at 的区别
be good at 意为“擅长……，在某方面干得好”，后接名词、代词或动名词。

I am good at playing basketball.
My good friend is good at Chinese.
【易错点】介词for与at的混淆
【考题链接】
1. It’s good us to walk.
A. at
B. for
C. to
D. of
答案：B
解题思路：be good for是固定短语，意思是“对……有益”。

句意为：散步对我们有益处。

所以选B。

2. My friend Bill is good English.
A. in
B. on
C. for
D. at
答案；D
解题思路：be good at 意思是“擅长，在某方面学得好”。

句意为：我的朋友比尔英语学得好。

所以选D。

◎look after
【用法】look after意为“照看，照顾”，相当于take care of。

我们可以说look after sb. well 或take good care of sb.。

【例句】1. I have to look after my sister at home.
2. Please look after your baby well.
= Please take good care of your baby.
【考查点】look和一些介词的搭配：look at, look for, look up, look like等。

【易错点】在具体的语境中没弄懂这些固定短语的意思。

【考题链接】
My mother is ill, so I must her at home.
A. look at
B. look for
C. look after
D. look up
答案：C
解题思路：look at意为“看”；look for意为“寻找”；look up 意为“抬头看；查（字典）”；
look after意为“照顾，照料”，由句意“妈妈病了，因此我必须在家里照顾她。

”可排除A、B、D 三个选项。

故答案选择C。

［即学即练］
1. An apple a day is good your health.
A. to
B. of
C. for
D. in
2. Mrs. Brown isn’t here. She has to her baby at home.
A. look at
B. look for
C. look like
D. look after
（三）重点句型
［句型学习］
◎How often do you watch TV?
【用法】how often 用来询问动作的频率，即动作“多长时间发生一次”，回答可用once / twice / three times a day“一天一（两、三）次”，sometimes“有时”，never“从不”，very often“经常”等。

【例句】1. —How often do you read English books? —Every day.
2. —How often does he go to the movies? —Twice a month.
【考查点】how often, how long, how far, how soon的辨析
how long 主要用来提问多长时间。

答语通常是表示一段时间的状语。

例如：
—How long did you stay there?
—Two hours.
how far“多远”，用于询问两地间的距离，答语要用表示距离的词语。

例如：
—How far is it from here to the hospital?
—About ten minutes’ walk.
how soon意为“多久以后”。

时态多用将来时或含有将来意义的其他形式，答语常用 in a week类短语。

例如：
—How soon will you come back?
—In a week.
【易错点】没有真正掌握这几个疑问词的用法
【考题链接】
1. — do you go to see a film?
—Sometimes.
A. How long
B. How often
C. When
D. How soon
答案：B
解题思路：how long 意为“多长时间”；how often意为“多久一次”；when意为“什么时候”；how soon意为“多久以后”；本句中答语为sometimes“有时”，表“频率”，可知本题答案为B。

句意为：你多久看一次电影？有时。

2. — do you go to the library?
—I usually go to the library twice a week.
A. How long
B. How often
C. How far
D. How many
答案：B
解题思路：how long表示“多长时间”，用来提问时间的长短，回答时用表示一段时间的状语；how often表示“多长时间一次”，用于询问在某短时间里动作的频率，回答时用表示频率的副词或短语。

如：sometimes, often, never, once a week, every day等；how far用于提问距离；how many后接可数名词的复数表示“多少”，用于询问数量。

所以本题选B。

◎Good food and exercise help me to study better.
【用法】help sb. to do sth.意为“帮助某人做某事”，此处的动词不定式符号to可要可不要。

同义词组为help sb. with sth.。

【例句】1. Lucy often helps me learn English.
= Lucy often helps me with my English.
2. I often help my mother do the housework.
=I often help my mother with the housework.
【考查点】help sb. (to) do sth. 与help sb. with sth. 的转换
【易错点】不知道help后用动词的哪种形式
【考题链接】
Talking with native speakers helps me English better.
A. study
B. studying
C. studies
D. studied
答案：A
解题思路：本题考查固定搭配的使用。

help接动词不定式作宾语补足语，to可要可不要。

答案选A。

［即学即练］
1. — do you water the plants?
—Twice a day.
A. How long
B. How soon
C. How often
D. How much
2. He often helps me (do) some housework. （用所给动词的适当形式填空）

4. 本句的意思是“他没有去上学，他感到有点不舒服。

”sick为形容词，而a kind of, kinds of后加名词，表示种类，可排除B、C；a kind不正确；kind of常用于口语，意为“有点，有几分”，多用于修饰形容词或副词，表程度。

所以选A。

10. Doing morning exercises在句中是动名词作主语，谓语动词要用第三人称单数形式。

be good for 对……有益；be good at擅长；所以选C。
