六. 重、難點(diǎn)解析
1. 頻度副詞
always, usually, often, sometimes, hardly和never是英語中最常見的頻度副詞，它們?cè)诰渲械奈恢么笾孪嗤和ǔ７旁谛袨閯?dòng)詞之前，系動(dòng)詞be、助動(dòng)詞和情態(tài)動(dòng)詞之后。但它們所表示的含義及頻度是各不相同的。
（1）always的頻度為100%，表示動(dòng)作重復(fù)、狀態(tài)繼續(xù)，中間沒有間斷，意思是“總是”、“永遠(yuǎn)地”。例如：
The sun always rises in the east and sets in the west.
太陽總是東升西落。
Customers are always right.
顧客永遠(yuǎn)是對(duì)的。
▲always與進(jìn)行時(shí)態(tài)連用，并不強(qiáng)調(diào)動(dòng)作正在進(jìn)行，而是表示說話人的“贊揚(yáng)”、“不滿”、“厭煩”等情緒，有強(qiáng)烈的感情色彩。例如：
She is always thinking of how she can do more for people.
她總是在考慮怎樣為人們多做些事。（表示贊揚(yáng)）
He was always asking for money.
他總是要錢。（表示厭煩）
She is always asking for leave.
她總是請(qǐng)假。（表示不滿）
▲always與not連用，表示部分否定，意思是“不總是”。例如：
The rich are not always happy.
有錢人未必總是幸福的。
（2）usually的頻度為70%左右，意為“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點(diǎn)鐘睡覺。
（3）often的頻度為50%左右，意為“常常”，但不如usually那么頻繁，表示動(dòng)作重復(fù)，中間有間斷。例如：
He is often late for school.
他上學(xué)經(jīng)常遲到。
▲very often語氣比often重，常位于句首或句末。例如：
He doesn’t go to London very often.
他不常去倫敦。
（4）sometimes的頻度為20%左右，意為“有時(shí)”，表示動(dòng)作偶爾發(fā)生。可以位于句首，以示強(qiáng)調(diào)。例如：
It is sometimes hot and sometimes cold.
天氣忽冷忽熱。
Sometimes he does it this way and sometimes he does it that way.
他有時(shí)這樣做，有時(shí)那樣做。
（5） hardly的頻度為5%左右，意為“幾乎不”、“簡(jiǎn)直不”，常和ever連用表示強(qiáng)調(diào)。例如：
I hardly ever go out these days.
這些天我?guī)缀醪怀鲩T。
（6）never的頻度為0，意為“從來不”、“永不”。例如：
My parents are never late for work.
我父母上班從來不遲到。
2. 注意sometimes與幾個(gè)形似的詞的區(qū)別。
a. sometime是副詞，意為“在某個(gè)時(shí)候”，“某時(shí)”
eg：Will you come again sometime next week?
She was there sometime last year.
b. some time是名詞詞組，意為“一段時(shí)間”，做時(shí)間狀語用
eg：I will stay here for some time.
He worked on the trouble for some time.
c. some times是名詞詞組，意為“幾次，幾倍”。
eg：I met him some times in the street last month.
The factory is some times larger than that one.
3. 不定代詞all“全部”，most“大部分”，some“一些”，no“沒有一個(gè)”的用法，這些詞可以在句中作主語、賓語、表語或定語。
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.
Gina has some beautiful scarfs.
No children can sing this song.
4. 疑問詞how的用法
（1）怎樣，用什么手段，方法。
How did he do it?
I don’t know how to swim.
（2）情況如何（指身體健康狀況）
How are you?
How’s it going with Tom?
（3）how many，how much表示“多少”
how many后接可數(shù)名詞復(fù)數(shù)，how much接不可數(shù)名詞。
How many times do you go to the park?
How many tickets do we need?
How much water is there?
How much are those pants?
（4）how often是對(duì)動(dòng)作發(fā)生的“次數(shù)”提問
eg：How often do you play tennis?
How often do you surf the internet.
5. time表示不可數(shù)名詞，意為“時(shí)間”。
表示可數(shù)名詞，意為“次數(shù)，倍數(shù)”。
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“次數(shù)”的表達(dá)方法
一次 once
兩次 twice
三次或三次以上用基數(shù)詞加上times，three times、five times、one hundred times.
表示“……幾次”的表達(dá)方法是：twice a month、once a month、three times a week、once a year.
6. be good for意為“對(duì)……有好處”，其反義詞為“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意為“就……而論”，“至于”
eg：As for fruit，I eat it sometimes.
8. want sb to do.意為“想讓某人做某事”。
eg：He wants me to do exercise every day.
His mother wants him to be a reporter.
有很多動(dòng)詞后面用這種結(jié)構(gòu)做動(dòng)詞的復(fù)合賓語。
如：ask sb. to do sth.
tell sb. to do sth.
help sb. (to) do sth.等
9. exercise的用法。
（1）作可數(shù)名詞復(fù)數(shù)exercises。意為“運(yùn)動(dòng)、體操”。
（2）作不可數(shù)名詞，意為“練習(xí)、習(xí)題”。
eg：I have to do so much exercise.
He bought a new exercise book.
（3）作動(dòng)詞，意為“練習(xí)、運(yùn)動(dòng)”。
eg：-How often do you exercise?
-I exercise every day.
七. 課文解析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”作副詞用，我們以前學(xué)過quite和very也有這種意思。其中它們的程度由淺入深為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.
我每天鍛煉身體，通常是放學(xué)后。
3. eating habits“飲食習(xí)慣”。
4. try to do sth意為“盡力去做某事”。
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”。
注意這種表達(dá)。“to”為介詞。
翻譯：（1）兩到三次。
twice to three times.
（2）每月四到五次。
four to five times a month.
6. Of course. “當(dāng)然”。
7. So you see, I look after my health.
“所以你看，我很在意我的健康”。
look after 意為“照顧、照看”。
eg：Can you look after my baby when I leave?
Please look after your own bags carefully.
look還可以和許多詞搭配，但意思不一樣。
（1）look at“看，認(rèn)真地看”。
eg：Please look at the blackboard.
Some people are looking at the notice.
（2）look for“尋找”
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.
好的飲食和鍛煉幫助我學(xué)得更好。
