The keys to reaching or staying at a healthy weight are regular exercise and good eating habits. Teens should get 60 minutes or more of physical activity a day. Note the word “activity”. As long as you’re getting your body moving, it doesn’t have to mean doing difficult exercise or going to the sports hall every day. All that matters is that each week you get the right balance of activity, including aerobics (有氧運動), strength building, and flexibility (柔韌) exercise. Make exercise a habit by arranging some time every day.
On days when you have soccer practice or an aerobics class, you may have no trouble exercising for an hour or more. But most of us are busy, and 60 minutes a day for exercise seems like a lot of time. The good news is that it’s OK to divide it into shorter exercise breaks throughout the day.
Just as you might have a healthy snack to stop yourself from getting hungry, exercise snacks can keep energy levels high. So get up 15 minutes early and do some stretching (伸展) activity. Walk fast or run slowly for 15 minutes after lunch. Do the same thing after school — or walk or bike home. Add to that taking the stairs, PE class, and walking between classes during the day, and you’ve probably reached your 60 minutes.
Here are five simple ways to make an exercise lifestyle change:
小題1:The writer thinks many people probably misunderstand the word“activity” to be “_______”.  
A．physical activityB．body movement
C．sports hall exerciseD．outdoor exercise
小題2:When exercising, the most important fact is ________.
A．the time spent on exercise
B．the intensity of activity
C．the difficulty of exercise
D．the right balance of activity
小題3:The author advises dividing activity into shorter exercise breaks because ___.
A．exercising for a long time is bad for people’s health
B．it has the same effect as soccer practice
C．people usually haven’t much time to exercise
D．no one can spare lots of time to exercise
小題4:What’s the best title for this passage?
A．Regular exercise.B．School exercise.
C．Indoor exercise.D．Difficult exercise

小題1:C
小題2:D

小題4:A

I really love my job because I enjoy working with small children and like the challenges and awards from the job. I also think my work is important. I wasn’t an excellent student because I didn’t do much schoolwork. In my final term I started thinking what I might do and found I didn’t have much to offer.
I then found myself a job, looking after two little girls. It wasn’t too bad at first. But the problems began when I agreed to live in. I would be there if my boss had to go out for business in the evening. We agreed that if I had to work extra hours one week, she’d give me time off the next. But unluckily, it didn’t often work out. I was getting very tired. Because I had too many late nights and early mornings with the children.
One Sunday, I was in the park with the children, and met Megan who used to go to school with me. I told her about my situation. She suggested that I should do a course and get a qualification（資格證書）if I wanted to work with children. I didn’t think I would be accepted because I didn’t take many exams in school. She asked me to phone the local college and they were really helpful. My experience counted for a lot and I got on a part-time course. I had to leave my job with the family, and got work helping out at a kindergarten.
Now I’ve got a full-time job there. I shall always be thankful to Megan. I wish I had known earlier that I could have a success, even if I am not top of the class at school.

Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.
The eye-recognition（眼睛識別 program has already been tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon this technology（技術(shù)） will take the place of all other ways of finding out who people are.
However, scientists are also working on other systems. Machines will soon be able to know you from the shape of your face or hand or even your smell! We already have machines that can tell who you are from your voice or the mark made by your finger.
Eye-recognition is better than other kinds because your eyes don’t change as you get older, and don’t get dirty like hands or fingers, and even twins have different eyes. So the eye-recognition program can be up to 94% correct, depending on how good the technology is. However, some other programs may only be 51% correct at present. In Britain, it was found that 91% of people who had tried it said that they liked the idea of eye-recognition.
In the future your computer will be looking you in the eye. So smile!
小題1:Where has the eye-recognition program already been tested in a few countries? In_______.

  We use the Internet for many things: business, shopping, writing letters, talking to people, finding information and so on. In recent years a new kind of English has grown on the Internet. There’s no real word for it yet, so we’ll call it e-talk. People don’t like typing too much. To save time, they turn phrases into a few letters called acronyms. Acronyms are often used in chat rooms. Some of them are
BTW (by the way)        BRB (be right back)
LOL (laughing out loud)    IMO (in my opinion)
People also use many abbreviations(縮寫). They are shortened forms of words. Some common abbreviations are:
Info(information)       puter (computer)
Pie(picture)           sec (second)
We usually don’t see people when we communicate on the Net, so people have new ways to show feelings. Most people use their keywords to draw “feeling”, such as:
:-)(happy)    :-p(joking)   :-( (sad)    :-0 (surprised)
These days, many forums(論壇) have picture feelings. For example,

(sad)      (happy)
There are even whole new words, like“newbie’s”(someone who is new on a chat board or forum).
It takes time for people to get used to e-talk. Also, different groups on the Net have their own special ways of communicating. Newbie’s have to ask other people what they mean. As the Internet grows, e-talk will continue to grow and change.
小題1:What does the underlined word “acronyms” mean?
A．網(wǎng)友B．聊天室C．首字母縮寫詞D．關(guān)鍵詞
小題2:Why do people type acronyms?
A．To show their feelings.
B．Because people can type them quickly.
C．In this way newbie’s won’t understand them.
D．To make people use Internet
小題3:What does “BTW, my puter is not working well. :- ( ” mean ?
A．The person is angry at somebody.
B．The person is happy about getting a new computer
C．The person is sad that his computer is having problems.
D．The person is joking that his computer is having problems.
小題4:E-talk will probably _______.
A．keep changing
B．be easy by people on the telephone
C．be used by people on the telephone
D．make life easier
小題5:What’s the best title for this passage?
A．E-talk LanguageB．Picture Feelings
