五、重、难点解析：
1. Let's look at the following words and their usage.
频度副词：always, usually, often, sometimes, hardly和never是英语中最常见的频度副词，它们在句中的位置大致相同：通常放在行为动词之前，系动词be、助动词和情态动词之后。但它们所表示的含义及频度是各不相同的。
（1）always的频度为100%，表示动作重复、状态继续，中间没有间断，意思是“总是”、“永远地”。例如：
The sun always rises in the east and sets in the west. 太阳总是东升西落。
Customers are always right. 顾客永远是对的。
▲always与进行时态连用，并不强调动作正在进行，而是表示说话人的“赞扬”、“不满”、“厌烦”等情绪，有强烈的感情色彩。例如：
She is always thinking of how she can do more for people. 她总是在考虑怎样为人们多做些事。（表示赞扬）
He was always asking for money. 他总是要钱。（表示厌烦）
She is always asking for leave. 她总是请假。（表示不满）
▲always与not连用，表示部分否定，意思是“不总是”。例如：
The rich are not always happy. 有钱人未必总是幸福的。
（2）usually的频度为70%左右，意为“通常”、“平常”，即很少有例外。例如：
He usually goes to bed at ten o’clock. 他通常10点钟睡觉。
（3）often的频度为50%左右，意为“常常”，但不如usually那么频繁，表示动作重复，中间有间断。例如：
He is often late for school. 他上学经常迟到。
▲very often语气比often重，常位于句首或句末。例如：
He doesn’t’t go to London very often. 他不常去伦敦。
（4）sometimes的频度为20%左右，意为“有时”，表示动作偶尔发生。可以位于句首，以示强调。例如：
It is sometimes hot and sometimes cold. 天气忽冷忽热。
Sometimes he does it this way and sometimes he does it that way. 他有时这样做，有时那样做。He sometimes goes to movies on Friday evening. 他有时周五晚上去看电影。
（5） hardly的频度为5%左右，意为“几乎不”、“简直不”，常和ever连用表示强调。例如：
I hardly ever go out these days. 这些天我几乎不出门。
（6）never的频度为0，意为“从来不”、“永不”。例如：
My parents are never late for work.我父母上班从来不迟到。
2. 注意sometimes与几个形似的词的区别。
(1) sometime是副词，意为“在某个时候”，“某时”
eg：Will you come again sometime next week?
She was there sometime last year.
(2) some time是名词词组，意为“一段时间”，做时间状语用
eg：I will stay here for some time.
He worked on the trouble for some time.
(3) some times是名词词组，意为“几次，几倍”。
eg：I met him some times in the street last month.
The factory is some times larger than that one.
3. 不定代词all“所有的，全体的”，most“大部分的，大多数的”，some“一些”，no“没有一个”的用法，这些词可以在句中作主语、宾语、表语或定语。
eg：All the waiters in the restaurant are very busy.
All the students in our school have to wear school uniforms.
I know most people in this party.
Most students play computer games on weekends.
Gina has some beautiful scarfs.
Some students go to English movies every day.
No children can sing this song.
all, most, some, no 放在名词的前面做定语，表示数量的多少。
4. 疑问词how的用法
（1）怎样，用什么手段，方法。 How did he do it?
I don’t know how to swim.
（2）情况如何（指身体健康状况） How are you?
How’s it going with Tom?
（3）how many，how much表示“多少”
how many后接可数名词复数，how much接不可数名词。
How many times do you go to the park?
How many tickets do we need?
How much water do we need every day?
How much are those pants?
（4）how often是对动作发生的“次数”提问,询问的是频率“多久一次”
回答可以是：Every day./ Once a week./Three times a week./ Often./ ...
eg：How often do you play tennis?
How often do you surf the internet.
(5) How long... ? 询问的是时间长短“多长时间”
回答可以是：About one hour./ Three hours. / Thirty minutes./...
How long do you usually watch TV? 你通常看多长时间电视？
5. time表示不可数名词，意为“时间”。 表示可数名词，意为“次数，倍数”。
eg：What time is it?
Time and tide never wait for men.
I go to the movies three times a week.
The size of the new museum is four times larger than the old one.
注意“次数”的表达方法
一次 once， 两次 twice，三次或三次以上用基数词加上times，three times、five times、one hundred times.
表示“……几次”的表达方法是：once a day/ a week/ a month/ a year twice a day/ a week/ a month/ a year
6. She says it's good for health. 她说它对健康有利。
be good for意为“对……有好处”，其反义词为“be bad for”。
eg：Drinking milk is good for your health.
Eating too much sugar is bad for your teeth.
Reading English is good for studying English.
7. as for意为“就……而论”，“至于”
eg：As for fruit，I eat it sometimes.
8. My mother wants me to drink it. 我妈妈想要我喝。
want sb. to do sth. 想要某人干某事
eg：I want you to help me with my math.我想要你帮我学数学。
有很多动词后面用这种结构做动词的复合宾语。如：
ask sb. to do sth. tell sb. to do sth. help sb. (to) do sth.等
9. exercise的用法。
（1）作可数名词复数exercises。意为“运动、体操”。
（2）作不可数名词，意为“练习、习题”。
eg：I have to do so much exercise.
He bought a new exercise book.
（3）作动词，意为“练习、运动”。
eg：-How often do you exercise?
-I exercise every day.
10. 语法：一般现在时的特殊疑问句
1) What do you usually do on weekends?
2) What does he do on weekends?
3) How often do you shop?
4) How often does he watch TV?
5) How many hours do you sleep every night?
一般现在时的特殊疑问句的构成： 特殊疑问词+一般疑问句
这里的特殊疑问词指 what, what time, where, when, which, who, whom, whose, why, how, how many, how much, how long, how often
六、 课文解析SB. 3a
…but I’m pretty healthy. I exercise every day, usually when I come home from school. And my eating habits are pretty good. I try to eat a lot of vegetables, usually ten to eleven times a week. And I eat fruit every day and I drink milk every day. Of course, I love junk food, too, but I try to eat it only once a week, oh, and I sleep nine hours every night. So you see, I look after my health. And my healthy lifestyle helps me get good grade. Good food and exercise help me to study better.
1. pretty表示“十分”作副词用，我们以前学过quite和very也有这种意思。其中它们的程度由浅入深为quite→pretty→very.
eg：He is quite serious.
It sounds pretty good.
Nina can sing English songs very well.
2. I exercise every day, usually when I come home from school.我每天锻炼身体，通常是放学后。3. eating habits“饮食习惯”。
4. try to do sth意为“尽力去做某事”。 eg：Try to get here early.
He tried to pass the exam.
5. ten to eleven times a week.“每周十到十一次”。
注意这种表达。“to”为介词。
翻译：（1）两到三次。 twice to three times.
（2）每月四到五次。four to five times a month.
6. Of course. 当然。
7. So you see, I look after my health. 所以你看，我很在意我的健康。
look after 意为“照顾、照看”。
eg：Can you look after my baby when I leave?
Please look after your own bags carefully.
look还可以和许多词搭配，但意思不一样。
（1） look at“看，认真地看”。 eg：Please look at the blackboard.
Some people are looking at the notice.
（2） look for“寻找” eg：Old Henry looked for his dogs, but he didn’t find it.
I’m looking for my lost pen.
8. Good food and exercise help me to study better. 好的饮食和锻炼帮助我学得更好。

他们的同事C更进一步。他详细了解老总的奋斗历程，弄清老总毕业的学校，人际风格，关心的问题，精心设计了几句简单却有份量的开场 白，在算好的时间去乘坐电梯，跟老总打过几次招呼后，终于有一天跟老总长谈了一次，不久就争取到了更好的职位。
