We know that many animals do not stay in one place.Birds,fish and other animals move from one place to another at a certain time.They move for different reasons:most of them move to find food more easily,but others move to get away from places that are too crowded.
When cold weather comes,many birds move to warmer places to find food.Some fishes give birth in warm water and move to cold water to feed.The most famous migration(遷移)is probably the migration of fish,which is called “Salmon”.This fish is born in fresh water but it travels many miles to salt water.There it spends its life.When it is old,it returns to its birthplace in fresh water.Then it gives birth and dies there.In northern Europe,there is a kind of mouse.They leave their mountain homes when they become too crowded.They move down to the low land.Sometimes they move all the way to the seaside,and many of them are killed when they fall into the sea.
Recently,scientists have studied the migration of a kind of lobster(龍蝦).Every year,when the season of bad weather arrives,the lobsters get into a long time and start to walk across the floor of the ocean.Nobody knows why they do this,and nobody knows where they go.
So,sometimes we know why humans and animals move from one place to another,but at other times we don’t.Maybe living things just like to travel.

“Get your hands off me, I have been stolen,” the laptop, a portable computer, shouted. That is a new solution to laptop computer theft: a program that lets owners give their property a voice when it has been taken.
The program allows users to display alerts on the missing computer’s screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.
Owners must report their laptop missing by visiting a website, which sends a message to the model: a red and yellow “l(fā)ost or stolen” sign appears on its screen when it is started. Under the latest version(版本)of the software, users can also send a spoken message.
The message can be set to reappear every 30 seconds, no matter how many times the thief closes it.” One customer sent a message saying,’ You are being tracked. I am right at your door’,” said Carrie Hafeman, chief executive of the company which produces the program, Retriever.
In the latest version, people can add a spoken message. For example, the laptop’s speakers will say: “Help, this laptop is reported lost or stolen. If you are not my owner, report me now.”
The Retriever software package, which costs $29.95 but has a free trial period, has the functions of many security software programs .Owners can remotely switch to an alternative password if they fear that the thief has also got hold of the access details.
If a thief accesses the internet with the stolen laptop, Retriever will collect information on the internet service provider in use, so that the police can be alerted to its location.
Thousands of laptops are stolen every year form homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.
Other security software allows users to erase data remotely or lock down the computer.
小題1:The expression “to give the thief a piece of their mind “can be understood as “_______”
A.to give the thief an alert mind
B.to express the owners’ anger to the thief
C.to remind the thief of this conscience
D.to make the thief give up his mind
小題2:Different from other security software, Retriever can_______.
A.record the stealing processB.help recognize the lost laptop
C.lock down the computer remotelyD.send a spoken message
小題3: One function of the program is that it allows the owner to _______ at a distance.
A.change some access details for switching on the laptop
B.turn on the laptop by using the original password
C.operate the laptop by means of and alternative password
D.erase the information kept in the stolen laptop
小題4:Which of the following can best summarize the main idea of the passage?
A.With no Retriever, thousands of laptops are stolen every year.
B.A new soft ware provides a means to reduce laptop theft.
C.Retriever has helped to find thieves and lost computers.
D.A new program offers a communication platform with the thief.

If you've been joining in chat room conversations, or trading e-mail with Web pals, you have become one of the millions who write in a peculiarly short form of English.?
And you've got a sense of humor about short forms like SOHF(="sense" of humor failure) to describe Internet newcomers who don't understand you.
Across the globe, every night teenagers and their elders are “talking” online—many of them are talking at the same time.?
It's fast: try talking to six people at once. It's brief: three or four words per exchange. It takes wit, concentration, and quick fingers.?
And it requires tremendous linguistic economy. There's neither time nor space for explanations. Why consume precious key-strokes telling six friends you have to leave for a moment to take care of your little brother when BRB(="be" right back) will do? Want to enter a conversation? Just type PMFJI(="pardon" me for jumping in).  Interested in whom you're talking to? Type A/S/L, the nearly universal request to know your pal's age, sex and location. You may get 15/M/NY as a response from your pal.?
If something makes you laugh, say you're OTF(="on" the floor),or LOL(="laughing" out loud),or combine the two into ROTFL(="rolling" on the floor laughing).?
And when it's time to get back to work or go to bed, you type GTG(="got" to go) or TTYL(talk to you later).?
People want to write as fast as possible, and they want to get their ideas across as quickly as they can. Capital letters are left in the dust, except when expressing emotion, as it takes more time to hold down the “shift” key and capitals. Punctuation is going, too.?
小題1:In order to talk to several people at the same time on the Internet_______.
A.you have to speak fast and fluently?
B.you have to express your ideas in a brief way?
C.you should speak with wit and humor ?

LONDON — Life for Cathy Hagner and her three children is set to permanent(永久的) fast-forward.
Their full school day and her job as a lawyer's assistant are busy enough. But Hanger also has to take the two boys to soccer or hockey or basketball while dropping off her daughter at piano lessons or Girl Scout Club.
Often, the exhausted family doesn't get home until 7 pm. There is just time for a quick supper before homework. In today's world, middle-class American and British parents treat their children as if they are competitors racing for some finishing line.
Parents take their children from activity to activity in order to make their future bright. It seems that raising a genius has become a more important goal than raising a happy and well-balanced child.
“Doctors across the country are reporting a growing number of children suffering from stomachaches and headaches due to exhaustion and stress,” says child expert William Doherty of the University of Minnesota.
Teachers are dealing with exhausted kids in the classroom. It's a very serious problem. Many children attend after-school clubs by necessity. But competitive pressures also create an explosion of activities. They include sports, language, music and math classes for children as young as four.
“There is a new parenting trend(趨勢(shì)) under way which says that you have to tap all your child’s potential(潛能) at a young age; otherwise you will let him down,” says Terry Apter, a Cambridge-based child and adolescent psychiatrist(青少年精神病專(zhuān)家).
“It isn't entirely new: there have always been pushy parents. But what was previously(以前) seen as strange behaviour is now well accepted.”
小題1: From the second paragraph of this passage we can find that _______.
A.Hagner wastes much time helping her children's lessons
B.Hagner doesn't spend much time on her full-time job
C.Hagner is interested in sports and music
D.Hagner busies herself by following a trend
小題2:British parents, as the writer described in this passage, _______.
A.treat their children as sports players
B.pay no attention to their children's lessons
C.bring up their children in a simple way
D.give their children little time to develop freely
小題3:The writer's opinion about after-school clubs is that ________.
A.a(chǎn)ctivities in the country are too competitive
B.children should attend four clubs at a time
C.some clubs result in competitive pressures
D.clubs should have more subjects for school children
小題4:The last paragraph tells us that in Britain _______.
A.parents used to take their children to every club
B.parents used to be wise on how to raise children
C.parents have all benefited from children’s clubs
D.parents have come to know the standard of education

There have always been a lot of commonly believed but false ideas about being fat and doing exercise. Some people believe that they can’t help putting on weight as they get older, while others hold that if they stop exercising, their muscles will turn into fat. Here are some more myths:
I’ll never lose weight --- I come from a fat family
Wrong! While we can’t change the body type we are born with, we can’t blame our genes for making us fat. There’s plenty of evidence that fatness runs in families, and the main reason is that they share the same habits of eating too much and exercise too little.
I am fat because I burn calories slowly
Wrong! Fatness is not caused by a slow metabolism(新陳代謝). If fact, although fat people consume more energy that slim people, they also fail to realize how much they eat! Keeping a diary can help you work out your daily food intake more accurately.
Exercise is boring
Wrong! Anything will become boring if you do it repetitively. The key is to develop a balanced and varied program that’s fun as well as progressive. If you enjoy a Sunday walk, take a different route. If you do Yoga, try a tai chi class. If you like swimming, set yourself a distance or time challenge.
No pain, no gain
Wrong! Exercise is not meant to hurt. Indeed, pain is your body telling you something’s wrong, and continuing to exercise could lead to serious injury. You may experience mild discomfort as you begin to exercise regularly, but this your body adapting to the positive changes in your lifestyle and the aches should disappear relatively quickly. If you don’t, rest and seek medical advice.
小題1:What does the author think about being fat?
A.It is the family genes that make people fat.
B.People are fat because they consume too little energy.
C.A diary of exercise can prevent people from becoming fat.
D.It is the consequence of people’s unbalanced lifestyle.
小題2:According to the author, how can we make exercise more interesting?
A.By taking varied exercise.
B.By choosing simple exercise.
C.By doing regular exercise.
D.By sticking to outdoor exercise.
小題3:What is the author’s opinion about “No pain, no gain” in exercising?
A.Keeping fit is essentially a painful experience.
B.Exercise should be stopped if continuous pain is felt.
C.Pain in exercise is a precondition for reaching your goal.
D.Getting used to pain leads to positive changes in your body.
小題4:What is the purpose of the passage?
A.To declare the importance of keeping fit.
B.To clarify some misconceptions about fatness and exercise.
C.To confirm what has long been believed about keeping fit.
D.To explain some medical facts about being fat and doing exercise.

People say time is relative.But relative to what.I do know that sometimes time“seems”to be moving slower.Remember Christmas Eve when you were a child? It was the longest night of the year.It lasted forever! And now it seems like I just paid my bill yesterday...a(chǎn)nd it’s due again!  
People tell me all too frequently…I need more time! Oh ,really?…Mother Teresa,Michelangelo,and Helen Keller all had 24 hours a day.Look what they did with their time!
Is it that we need to manage our time better…or our priorities(重點(diǎn))?You’ve heard the expression“first things first.”The first step in understanding the power of time is to understand that it is limited.Why is it then that some people get a lot more done? We know the answer.They use their time smartly.   
One day an expert on time management was speaking to a group of students and announced a quiz.He pulled out a wide-mouthed jar.Next,he placed about a dozen fist-sized rocks,one at a time , into the jat, until no more would fit.“Is it full?” he asked.”Yes,”responds the class.”O(jiān)h really?” he asked.So he took out a bucket of gravel(砂礫), which he managed to work down into the spaces between the larger rocks.“Is it full now?” he asked.
Wising up,one answered,‘'Probably not.”Sure enough, he took out a bucket of sand,which he poured into the empty spaces.”Is it full now?” he asked.”No,” reply the students confidently.So he took a glass of water and filled it in.Then he asked,“What is my point?’’
One said,‘'No matter how full your schedule is,if you try really hard,you can always fit some more things into it!”
“No,”the speaker replied,“It tells us if you don’t put the big rocks in first, you’ll never get them in at all.’’
What are the big rocks? The things you should put in to your jar first.
The rich don’t get 25 hours and the poor don’t get 23…we all get the same.Let’s use them wisely! Invest your time wisely!
49.What does the point of the quiz lie in_______.
A.How to put more things into ajar. B.How well the students learn the lesson.
C.How to get more done in limited time      D.The skill and order is very important.
50. “The big rocks”in this passage refers to_______?
A.difficult points.        B.a(chǎn)dvantages     C.minor things           D.focuses
51. How is the passage mainly developed?
A.By inferring.             B.By comparing.
C.By listing examples.        D.By giving facts.
52. The text is written mainly            
A.to explain the origin of the expression “first things first”
B.to call on us to use our time in a smart manner   
C.to introduce a meaningful class given by an expert
D.to tell us about the relativity and the power of time
