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) 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4:D

小題2:本文第一段最后一句是You’ll just have to look at the machine and it will be able to tell who you are.意思為你只要看著機器,機器就能辨別你的身份,也就是說你只需要看著眼睛識別器,他就能工作和運轉,故本題選D。
小題3:本文第三段We already have machines that can tell who you are from your voice or the mark made by your finger.意思為我們已經有了機器能夠根據你的嗓音或者是你的指紋而辨別你的身份,故本題選B。

小題5:本文的第四段提到眼睛識別系統的準確性為百分之91,所以它的問題是不完全準確,故本題選C。

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

C
“Everything happens for the best.” Whenever I faced disappointment, my mother would say this to me.
After I graduated form college in 1932, I decided to find a job in radio as a sports announcer(廣播員). I went to Chicago and knocked at the door of every station. But unluckily, I was refused every time.
At one station, a kind lady told me that big stations wouldn’t hire(雇傭) a person without any experience and suggested that I try my luck at smaller stations. Following her advice, I went back to Dixon, where I had grown up. There were no such jobs in Dixon, and my father said a newly-opened store wanted a local athlete to work for it. I wanted this job, but I was refused again.
“Everything happens for the best,” Mom reminded me. Dad offered me the car to look for a job. I tried WOC Radio in Davenport, Iowa. The program director, Peter MacArthur, told me they had already hired an announcer.
As I left his office, I felt so frustrated. “How can I become a sports announcer if I can’t get a job in a radio station?” I asked aloud.
While I was waiting for the elevator, I heard someone calling. It was MacArthur. “What was that you said about sports? Do you know anything about football?” Then he asked me to have a try. He was pleased with my performance, and he offered me a chance to work there.
On my way home, I thought of my mother’s words: “If you carry on, one day something good will happen. Something wouldn’t have happened if without the failure before.”
小題1:Why couldn’t the writer find a job at big radio stations?
A.Because he never graduated from college.
B.Because he didn’t work hard in college.
C.Because he didn’t have much experience.
D.Because he didn’t know about sports.
小題2:Which of the following is the correct order of events?
a. The writer got a job as a sports announcer at a radio station.
b. The writer was refused when he wanted jobs in Chicago.
c. The writer graduated from college.
d. The writer went back to his hometown to look for a job.
A.cbdaB.cbadC.bcdaD.bcad
小題3: Which of the following is TRUE?
A.The writer’s parents didn’t want him to be a sports announcer.
B.There were no radio announcer jobs in the writer’s hometown.
C.The writer became uninterested in being a sports announcer.
D.The writer got a job as a sports announcer in Dixon at last.
小題4: According to the last paragraph, what did the writer’s mom want to tell him?
A.He shouldn’t be a sports announcer.
B.Disappointment leads to failure.
C.He should be proud of himself.
D.Everything will be OK if he keeps trying.

Someone is singing next door, but you feel unhappy because her singing is terrible. So you think she is just making noise. We know that too much noise makes people feel terrible.
Scientists are still trying to find out more about noise, but already it is known that a noise of over 85 decibels(分貝) can make some people tried and anxious(焦慮的).
In the past we thought only workers in very noisy places became deaf easily. Today, scientists believe that 10% of all workers in Britain become deaf in their work.
There are also new dangers from noise. Pop music, for example, can reach 120 decibels when it is played loudly five feet away! Only a plane can make such loud noise when it takes off.
There was an experiment in the United States. Some people would be given a lot of money if they stood below a jet when it was taking off over their heads. No one got the money after the jet flew past because all of them died in the noise.
People can’t pay their attention on what they are doing when there is much noise. Workers in noisy offices, for example, do their work more slowly than workers in quiet offices. Another study shows that workers in factories can do dull(枯燥的) jobs better when lively music is played for them.
