It is nice to know what the weather will be like when we plan a trip. Do you know anything about the history of weather? Don’t look at the sky. Don’t look for old weather reports. Looking at the tree rings is more important. Correct weather reports date back only one century, but some trees can provide an exact record of weather even further back.
It is natural that a tree would grow best in a climate with plenty of sunlight and rainfall. It is also expected that little sunlight or rainfall would reduce the growth of a tree. The change from a favorable to an unfavorable climate can be found out by the reading pattern of rings in a tree trunk. To find out the weather of ten years ago, you can count the rings of a tree trunk from the outside to the inside. If the tenth ring is far from the other rings, then it is certain that plenty of sunny and rainy weather occurred. If the rings are close together, then the climate was bad for the tree.
Studying trees is important not only for the history of weather, but also for the history of man. In an area of New Mexico you can find only sand — no trees or people. However, many centuries ago a large population lived there. They left suddenly. Why?
A scientist studied the pattern of the rings of dead trees that had grown there. He made up his mind that the people had to leave because they had cut down all the trees. Trees were necessary to make fires and buildings. So, after the people destroyed the trees, they had to move.
In this example studying tree rings uncovered an exciting fact about the history of man.

A woman named Emily renewing her driver’s license at the County Clerk’s office was asked to state her occupation. She hesitated, uncertain how to classify herself.
“What I mean is,” explained the recorder, “do you have a job, or are you just a …”
“Of course I have a job,” said Emily. “I’m a mother.”
“We don’t list ‘mother’ as an occupation… ‘housewife’ covers it,” said the recorder.
One day I found myself in the same situation. The clerk was obviously a career woman, confident and possessed of a high sounding title. “What is your occupation?” she asked.
The words simply popped out. “I’m a Research Associate in the field of Child Development and Human Relations.”
The clerk paused, ballpoint pen frozen in midair.
I repeated the title slowly, then I stared with wonder as my statement was written in bold, black ink on the official questionnaire.
“Might I ask,” said the clerk with new interest, “Just what you do in this field?”
Coolly, without any trace of panic in my voice, I heard myself reply, “I have a continuing program of research (what mother doesn’t), in the lab and in the field (normally I would have said indoors and out). Of course, the job is one of the most demanding in the humanities (any mother care to disagree?), and I often work 14 hours a day (24 is more like it). But the job is more challenging than most careers and rewards are more of a satisfaction rather than just money.”
There was an increasing note of respect in the clerk’s voice as she completed the form, stood up, and showed me out.
As I drove into our driveway, buoyed up (受鼓舞) by my glamorous new career, I was greeted by my lab assistants---ages 13, 7, and 3.
Upstairs I could hear our new experimental model (a 6 month old baby), in the child-development program, testing out a new vocal pattern.
I felt proud! I had gone on the official records as someone more distinguished and indispensable (不可缺少的) to mankind than “just another mother.”
Motherhood…What a glorious career! Especially when there’s a title on the door.
【小題1】What can we infer from the conversation between the woman and the recorder at the beginning of the passage?
A.The recorder was impatient and rude. |
B.The woman felt ashamed to admit what her job was. |
C.The author was upset about the situation that mothers faced. |
D.Motherhood was not recognized and respected as a job by society. |
A.curious | B.indifferent | C.puzzled | D.interested |
A.Because the author cared little about rewards. |
B.Because she thought the author did admirable work. |
C.Because she admired the author’s research work in the lab. |
D.Because the writer did something she had little knowledge of. |
A.To show how you describe your job affects your feelings toward it. |
B.To argue that motherhood is a worthy career and deserves respect. |
C.To show that the author had a greater job than Emily. |
D.To show that being a mother is hard and boring work. |

Millions of years ago dinosaurs (恐龍) lived on the earth. In the days of dinosaurs the whole earth was warm and wet. There were green forests and they could find enough to eat. Later, parts of the earth became cold and dry. and the forests there died. Then dinosaurs could not find enough to cat. This must be one reason why dinosaurs died out.
We can guess another reason. New kinds of animals came on the earth. Some had big brains and were fast and strong. They could kill dinosaurs. There may be other reasons that we don’t know about yet. Scientists are trying to make more discoveries about dinosaurs.
Dinosaurs were of many sizes and shapes (形狀). Some were as small as chickens, while some were about 90 feet long.
There were also terrible fights between dinosaurs. They might have happened more than 100 million years ago. Though there was no man to see any of the fights, we can be told by the animal’s footprints (足跡) that fight did take place.
【小題1】According to the passage, dinosaurs did exist only ______on the earth.
A.for millions of years |
B.millions of years ago |
C.more than 100 millions years ago |

Being green is everywhere these days, whether it is in the school, factory or anywhere on the Internet. This is because our planet is in danger, losing resources, polluting resources and destroying ecosystems(生態(tài)系統(tǒng)). Different species are dying because we can’t take care of our home. Now ask yourself why you don’t want a green healthier lifestyle and to save animals. Keep that in mind as you read on.
There are many ways to be green, first of all, everyone should recycle; it’s something easy and helps our planet in many ways. All you’d have to do is put recycling in recycling and garbage in garbage. Another popular thing is to try your best not to drive a car. Sometimes you can just walk, bike, or take a subway. This ensures that our air won’t be polluted, which in turn helps our lungs and everything else on our planet. Next thing is saving energy. We can do this by not using too much heat or air conditioning in summer or winter. It’s not preferable because it’s hard, but you can try and put your washing machine on cold whenever possible and try to keep electronics out of the rubbish. What’s more, remember to stop drinking from plastic bottles because plastic can only be used once and if used many times, it will become unhealthy. So you’d better use a glass or buy a reusable water bottle. The last and most important thing is, spread this news to the world and tell them what’s happening in our world. I’ve only listed a small part of the endless possibilities to save this world. The least you can do is do the simple ones.
【小題1】What does the underlined word “that” in Paragraph 1 refer to?
A.The importance of being green. |
B.The question asked in this paragraph. |
C.The present situation of the Earth. |
D.The reader’s contribution to the Earth. |
A.Two. | B.Three. |
C.Four. | D.Five. |
A.call on others to protect our Earth |
B.recycle what we have used |
C.try our best to stop driving cars |
D.save as much energy as possible |
A.tell us the importance of protecting our Earth |
B.Help us to cut down the pollution on our Earth |
C.teach us some knowledge about our health today |
D.guide us to some ways of protecting our Earth |

Most people know precious gemstones (寶石) by their appearances. An emerald flashes deep green, a ruby seems to hold a red fire inside, and a diamond shines like a star. It’s more difficult to tell where the gem was mined, since a diamond from Australia or Arkansas may appear the same to one from the Democratic Republic of the Congo. However, recently, a team of scientists has found a way to identify a gemstone’s origin.
Beneath the surface of a gemstone, on the tiny level of atoms and molecules(分子), lie clues (線索) to its origin. At this year’s meeting of the Geological Society of America in Minneapolis, Catherine McManus reported on a technique that uses lasers (激光) to clarify these clues and identify a stone’s homeland. McManus directs scientific research at Materialytics, in Killeen, Texas. The company is developing the technique. “With enough data, we could identify which country, which mining place, even the individual mine a gemstone comes from,” McManus told Science News.
Some gemstones, including many diamonds, come from war-torn countries. Sales of those “blood minerals” may encourage violent civil wars where innocent people are injured or killed. In an effort to reduce the trade in blood minerals, the U.S. government passed law in July 2010 that requires companies that sell gemstones to determine the origins of their stones.
To figure out where gemstones come from, McManus and her team focus a powerful laser on a small sample of the gemstone. The technique is called laser-induced breakdown spectroscopy. Just as heat can turn ice into water or water into steam, energy from the laser changes the state of matter of the stone. The laser changes a miniscule part of the gemstone into plasma, a gas state of matter in which tiny particles(微粒)called electrons separate from atoms.
The plasma, which is superhot, produces a light pattern. (The science of analyzing this kind of light pattern is called spectroscopy.) Different elements produce different patterns, but McManus and her team say that gemstones from the same area produce similar patterns. Materialytics has already collected patterns from thousands of gemstones, including more than 200 from diamonds. They can compare the light pattern from an unknown gemstone to patterns they do know and look for a match. The light pattern acts like a signature, telling the researchers the origin of the gemstone.
In a small test, the laser technique correctly identified the origins of 95 out of every 100 diamonds. For gemstones like emeralds and rubies, the technique proved successful for 98 out of every 100 stones. The scientists need to collect and analyze more samples, including those from war-torn countries, before the tool is ready for commercial use.
Scientists like Barbara Dutrow, a mineralogist from Louisiana State University in Baton Rouge, find the technique exciting. “This is a basic new tool that could provide a better fingerprint of a material from a particular locality,” she told Science News.
【小題1】We learn from Paragraph 1 that __________.
A.a(chǎn)n emerald and a ruby are names of diamonds. |
B.it’s not difficult to tell where the gem was mined. |
C.a(chǎn)ppearances help to identify the origin of gemstones. |

Space is where our future is — trips to the Moon, Mars and beyond. Most people would think that aside from comets(彗星) and stars, there is little else out there. But, since our space journey started we have left so much trash(垃圾) there that scientists are now concerned that if we don't clean it up, we may all be in mortal (致命的)danger.
The first piece of space junk was created in 1964, when the American satellite Vanguard I stopped operating and lost its connection with the ground center. However, since it kept orbiting around the Earth without any consequences, scientists became increasingly comfortable abandoning(拋棄) things that no longer served any useful purpose in space.
It is estimated (估計(jì))that there are now over 500,000 pieces of man-made trash orbiting the Earth at speeds of up to 17,500 miles per hour. The junk varies from tiny pieces of paint chipped off rockets to cameras, huge fuel tanks, and even odd items like the million-dollar tool kit that astronaut Heidemarie Stefanyshyn Piper lost during a spacewalk.
The major problem with the space trash is that it may hit working satellites and damage traveling spacecraft(飛船). Moreover, pieces of junk may collide(碰撞) with each other and break into pieces which fall back to the Earth. To avoid this, scientists have invented several ways for clearing the sky. Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space shuttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there.
【小題1】What was the first piece of man-made space trash?
A.A camera. | B.A tool kit. |
C.A fuel tank. | D.A broken satellite. |
A.It no longer served any useful purpose. |
B.It was millions of miles away from the Earth. |
C.It did not cause any problems. |
D.It was regarded as similar to comets and stars. |
A.It is huge, heavy machines. |
B.It never changes position. |
C.It floats slowly around the Earth. |
D.It may cause problems for space shuttles. |

The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true.
Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by SO2 is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in pollution at the same time.
【小題1】 _________, our world is becoming much smaller.
A.Because of the rise in pollution |
B.Thanks to science development |
C.Because the earth is being polluted day and night |
D.Because the earth is blown away by the wind every year |
A.much easier than | B.a(chǎn)s easy as |
C.much harder than | D.a(chǎn)s hard as |
A.rubbish | B.noise pollution |
C.a(chǎn)ir pollution | D.water pollution |
A.it makes much noise |
B.it makes us angry more easily |
C.it makes our rivers and lakes dirty |
D.it’s bad for all living things in the world |
A.Many countries are making rules to fight pollution. |
B.The pollution of the earth grows as fast as the world population does. |
C.The problem of pollution is not so serious because there are not so many people on the earth. |
D.If people could go to work by bus or bike instead of car or motorbike, it would be helpful in fighting against the problem of SO2. |

When something goes wrong,it can be very satisfying to say,“Well, it’s so-and-so’s fault.” or “I know I’m late,but it’s not my fault;the car broke down.” It is probably not your fault,but once you form the habit of blaming somebody or something else for a bad situation,you are a loser. You have no power and could do nothing that helps change the situation. However, you can have great power over what happens to you if you stop focusing on whom to blame and start focusing on how to remedy the situation. This is the winner’s key to success.
Winners are great at overcoming problems. For example, if you were late because your car broke down, maybe you need to have your car examined more regularly. Or, you might start to carry along with you the useful phone numbers, so you could call for help when in need. For another example, if your colleague causes you problems on the job for lack of responsibility or ability, find ways of dealing with his irresponsibility or inability rather than simply blame the person. Ask to work with a different person, or don’t rely on this person. You should accept that the person is not reliable and find creative ways to work successfully regardless of how your colleague fails to do his job well.
This is what being a winner is all about—creatively using your skills and talents so that you are successful no matter what happens. Winners don’t have fewer problems in their lives; they have just as many difficult situations to face as anybody else. They are just better at seeing those problems as challenges and opportunities to develop their own talents. So, stop focusing on “whose fault it is.” Once you are confident about your power over bad situations, problems are just stepping stop on for success.
【小題1】According to the passage, winners .
A.deal with problems rather than blame others |
B.meet with fewer difficulties in their lives |
C.have responsible and able colleagues |
D.blame themselves rather that others |
A.a(chǎn)sk a more able colleague for help |
B.blame him for his lack of responsibility |
C.tell him to find the cause of the problem |
D.find a better way to handle the problem |
A.excuses for their failures | B.barriers to greater power |
C.challenges to their colleagues | D.chances for self-development |
A.A Winner’s Problem. | B.A Winner’s Secret. |
C.A Winner’s Opportunity. | D.A Winner’s Achievement. |
