Some people have it easy. When their kids ask them what they do at work, they can give a simple, direct answer: “I put out fires” or “I teach primary school”. As a theoretical physicist, I never had this luck. Society has come to expect many things from the physicists. It used to be that we only had to discover the basic laws of the world and supply the techniques that would power the next Silicon Valley. With these expectations we were fairly comfortable: they are the sorts of things we think we know how to do. What makes us uncomfortable and what makes it hard for us to tell our kids what we’re up to is that in this century we have become, though unwillingly, gurus on questions such as “What is the nature of Reality?”
We now deal with a whole new class of problems. We ask how the world began and what the nature of matter is. The answers we are coming up with are just not easy to comprehend for the average person.
So, when physicists get out of their cars in the morning, have a cup of coffee and sit down in front of their computers, they leave a familiar world and enter a place where things act in strange ways that are impossible for ordinary people to understand.
72. According to the passage, in a way physicists are .
A. honest B. comfortable C. strange D. unlucky
73. By what the writer says about physicists, we know that physicists .
A. don’t like their careers
B. live in two different worlds
C. are coming up with new answers to old questions
D. don’t have to tell people what they are doing
74. From the passage we can conclude that theoretical physicists .
A. contributed to the new industry in Silicon Valley
B. only have to answer the basic questions about the world
C. have disappointed the expectations of many people
D. have found it hard to make themselves popular
75. What’s the main idea of the passage?
A. Society seems to know a bit about physicists’ work.
B. Most people are expecting to know what physicists are doing.
C. Physicists are doing more and more difficult jobs.
D. It’s impossible for average people to know physicists’ work.
When I asked my daughter which item she would keep; the phone, the car, the cooker, the computer, the TV, or her boyfriend, she said” the phone”. Personally, I could do without the phone entirely, which makes me unusual. Because the telephone is changing our lives more than any other piece of technology.
Point 1 The telephone creates the need to communicate, in the same way that more roads create more traffic. My daughter comes home from school at 4:00 pm and then spends an hour on the phone talking to the very people she has been at school with all day. If the phone did not exist, would she have anything to talk about?
Point 2 The mobile phone means that we are never alone. “The mobile saved my life,” says Crystal Johnstone. She had an accident in her Volvo on the A45 between Otley and Skipton. Trapped inside, she managed to make the call that brought the ambulance(救护车) to her rescue.
Point 3 The mobile removes our secret. It allows marketing manager of Haba Deutsch, Carl Nicolaisen, to ring his sales staff all round the world at and time of day to ask where they are , where they are going, and how their last meeting went.
Point 4 The telephone separates us. Antonella Bramante in Rome says, “We worked in separate offices but I could see him through the window. It was easy to get his number. We were so near——but we didn’t meet for the first two weeks!”
Point 5 The telephone allows us to reach out beyond our own lives. Today we can talk to several complete strangers simultaneously ( 同时地) on chat lines (at least my daughter does. I wouldn’t know what to talk about). We can talk across the world. We can even talk to astronauts (if you know any) while they’re space-walking. And, with the phone line hooked up to the computer, we can access(存取) the Internet, the biggest library on Earth.

If we were to keep a record of all the things we worried about during a given period of time,we would discover—in reviewing them—that the great majority of our 16 never come to pass. This means that most of the time we 17 to worrying,even the constructive(建设性的)kind that prompts us to try to come up with a 18 to what is troubling us,is wasted. 19 ,we not only caused ourselves unnecessary mental pain,but also 20 valuable minutes and hours that could have been spent elsewhere.
To 21 this,it is often necessary to subject(使……遭受)potential 22 of worry to the coldly objective. Once,before a major 23 in front of a standing-room-only audience,a member of Arturo Toscanini’s orchestra approached(接近)the great Italian conductor with a terrible 24 on his face.“Maestro(大师),”the musician said 25 ,“my instrument is not working 26 .I cannot reach the 27 of E-flat.Whatever will I do?We are to 28 a few moments later.”
Toscanini looked with total 29 at the man.Then he 30 kindly and placed an arm around his shoulders.“My friend,”the maestro replied,“do not worry about it.The note E-flat does not 31 anywhere in the music that you will be 32 this evening.”
The next time we find ourselves in the middle of 33 about some matter,we might be wise to 34 and ask ourselves what the odds(几率)are of the problem really coming to 35 .We may be able to go on to something more constructive.

Europe’s deadly outbreak of a rare form of E. coli bacteria (大肠杆菌) has brought new attention to food safety issues. One of the problems when people get sick from food is that the simplest question is often difficult or even impossible to answer. Just what did the people eat that made them sick?
Of course, one way to avoid these medical mysteries is to keep dangerous organisms out of the food supply. This is easier said than done, but scientists keep looking for new ways.
Scientists in the United States have developed an experimental system that uses a high-tech optical scanner. The system is designed to identify the presence of contaminants(致污物) like soil or animal waste on fresh produce. These can be sources of E. coli. E. coli bacteria naturally live in the intestines(肠) of humans and many animals. Most kinds of E. coli are harmless but some can make people sick.
The new scanner can also show damage and imperfections that might make the produce unappealing to shoppers.
Scientists designed the system at a Department of Agriculture research center in Beltsville, Maryland. Moon Kim of the Agricultural Research Service led the team.
MOON KIM: “We were requested, we were asked, to develop a method to detect contamination in produce. So we started with the apple as the model sample.”
The scanner uses a high-speed camera placed over the conveyer belt that moves the produce along. As the apples move along the belt, the scanner captures images of each piece of fruit.
Moon Kim says the team hopes the system will be available before long.
MOON KIM: “We are targeting for development in commercial plants for the next several years.”
The scanner can direct a sorting machine to separate the bad apples from the good ones. The system is currently able to show the surface of only half the apple as it speeds by. The inventers hope to improve the process so it can show the whole surface.
1.What is the main topic of the text?
A.Bacteria. B.A high-tech scanner. C.A camera D.Food safety.
2.E. coli bacteria ______.
A.broke out all over the world B.comes from soil or animal waste
C.is extremely harmful to health D.does not cause illness
3.The high-tech scanner ______.
A.can help to sort out different fruits
B.make the produce appeal to shoppers
C.can only capture images of the whole apple
D.can identify the presence of contaminants
4.What can be inferred from the text?
A.The scanner needs to be improved.
B.The scanner will be available in the next several years.
C.Moon Kim is unwilling to develop the scanner.
D.The scanner is connected to a sorting machine.
Smiles and tears are part of life. But do you find enough time for laughing? I’m not asking if you experience lots of good times. Of course, we should laugh during the happy times. 1. . 2. But she wrote one about a more serious subject--cancer in children. The book is titled I WANT TO GROW HAIR, I WANT TO GROW UP. Erma talks with many children who have cancer and learns important lessons from them. She learns, for example, that cancer survivors(幸存者)know how they should smile at life, though they are receivingchemotherapy(化疗).
3. .Jessica’s leg was cut off at the knee because of cancer. She was learning to wear a prosthesis(假肢). Jessica told about playing soccer. She hit the ball hard with her foot. The ball flew off in one direction while her man-made leg flew another way. Then the brave girl lay on the floor, laughing happily.
As the saying goes, “ 4. ” Do you find plenty of time to laugh?
