Air pollution is a leading cause of cancer and classified among top human carcinogens (致癌物質(zhì)), said the International Agency for Research on Cancer (IARC), which is the World Health Organization's (WHO) cancer agency, on Oct 17,2013.“Our task was to evaluate the air everyone breathes rather than focus on specific air pollutants,” the IARC's Dana Loomis said in a statement. “The results from the reviewed studies point in the same direction the risk of developing lung cancer is significantly increased in people exposed to air pollution.”
In 2010, lung cancer resulting from air pollution killed 223,000 people worldwide, and there was also convincing evidence that it increases the risk of bladder (膀胱) cancer. Loomis said people in Asia, Eastern North America, some places in Central America and Mexico, as well as North Africa have relatively high exposure(暴露). Developing countries with large populations and booming manufacturing sectors, such as China, are particularly at risk. This week, Harbin, the capital city of Heilongjiang province, became the first Chinese city to officially suspend classes due to serious smog, really good for teachers and students.
Many developed countries face similar problems, although to a lesser(較少的、次要的) degree than most developing nations. Between 91 and 96 percent of Europeans living in cities are exposed to levels of PM2.5—tiny particles with a diameter of less than 2.5 micrometers—that are higher than the WHO safety limits.
Although both the composition and levels of air pollution can vary dramatically from one location to the other, the IARC said its conclusions apply to all areas of the world. “Given the scale of the exposure affecting people worldwide, this report should send a strong signal to the international community to take action without further delay,” said Christopher Wild, director of the IARC.

A young boy was sitting in the back seat of the car eating an apple. Hw asked his father, “Why does my apple turn brown?” His father answered,”“When the skin is removed, air reaches the flesh of the apple causes oxidarion. This changes the apple’s molecular structure and results in a brownish color.”The boy asked,“Dad,what are you
talking about?”
I know how that boy feels. Sometimes I want answers to some of those confusing questions that we all meet with, such as how to get through difficult times or what to do in a tough situation. I just want to get it right.
The problem is that I don’t always have the answer I need. Nobody else seems to have them, either. So I go on making mistakes and think that I’ll never get it right.
Often I didn’t know what to do. I often made poor choices, but I gradually improved. Then I realized that I don’t HAVE TO always get it right. I don’t have to always know what to do all the time. All I really need to do is try my best, learn from my mistakes and go on.
Dr. Leo Buscaglia once said, “ No one gets out of this world alive, so the time to live, learn, care, share, celebrate and love is now. That would be pretty hard to do when you’re waiting for all the answers first.”
So you got it wrong. You made a mistake. So what should you do next? Forgive yourself and try again. You may not get out of this world alive, but you can get plenty of life out of this world if you are not too worried about always getting it right.
【小題1】In the beginning, the author tells the story of a boy and his father to ____.
A.show that the father is very knowledgeable |
B.say something interesting about apples |
C.show that children nowadays ask more questions |
D.introduce the topic of the passage |
A.He admired his father very much. |
B.He knew what his father meant. |
C.He felt it was difficult to understand. |
D.He thought that he had learned a lot from his father. |
A.We can search the answers when enjoying life itself. |
B.We must make right choices as often as possible. |
C.People have many desires when they enter the world. |
D.It is hard to lead a happy and satisfying life. |
A.We should try to learn and understand the answers to questions. |
B.We should learn from our mistakes and try again. |
C.It is very important to try to avoid(避免) mistakes. |

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. |

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 __________.

Bend over, take a deep breath and drink some water! This is just one of hundreds of tips you might get if you have the hiccups(打嗝). Hiccups are so mysterious. We really don’t know why they start and why they stop.
Everyone has a favorite cure(治愈方法) for a case of the hiccups. Some people think that a good scare(驚恐) is necessary to get well. Others eat a teaspoon of sugar. Still others drink a glass of water with a knife in it.
An American man named Jack O’Leary said he had hiccupped 160 million times over a period of eight years. He tried 60,000 cures, but none of them worked. At last he prayed to Saint Jude, the saint of Hopeless cases, and his hiccupping stopped immediately.
It took a British plumber eight months to cure his hiccups. People from all over the world wrote him letters with suggestions for getting well. He tried them all, but the hiccups continued. Finally, he drank a “secret” mixture someone had sent him. By that evening his hiccups were gone.
Why did these cures work for these two men? No one really know. But people who have studied many cases of hiccups have an idea – hiccups usually go away if you believe in the cure.

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 Batsquatch is described as a great winged bat. It’s reported that it lives in the shadows(陰暗處) of Mt. Saint Helens. It has purple skin, red eyes and the character is quite similar to the bat’s. Since reports tell it likes eating small animals like chickens, goats and pigs, some believe that it is actually a flying primate(靈長(zhǎng)目動(dòng)物). But researchers say that it is more closely related to the fruit bat of northern America.
Fear still fills the hearts of men, women and children of Washington. In May of 1980 during the eruption of Mount Saint Helens, the Batsquatch showed itself in the shadows of clouds from the eruption. In 1994, a local mountaineer was able to take pictures of the Batspuatch making the rumor(謠言) seem real. During this event some farm animals seemed to disappear though luckily no humans were reported missing at the time. The local mountaineer told about his meeting with the Batsquatch. When he suddenly heard a loud deep voice from the shadows, the mountaineer was knocked down. He tried to look for the creature(生物) that had made the sound. He saw a great creature with purple wings in the sky. It looked like it was about 30 feet tall.
The mountaineer kept this story a secret in fear of being laughed at by others but when new stories came in about the Batsquatch he shared his story.
The reality of the Batsquatch can no longer be ignored. It is only a creature that is trying to live. Respect! This is how we should take news such as this. Respect for a living creature instead of fear.
【小題1】The rumor about the batsquatch makes people of Washington full of______
A.joy | B.surprise |
C.fear | D.a(chǎn)nger |
A.Because it was reported in the newspaper |

Global Positioning Systems (全球定位系統(tǒng)) are now a part of everyday driving in many countries.These satellitebased systems provide turnbyturn directions to help people get to where they want to go.However,they can also cause a lot of problems,send you to the wrong place or leave you completely lost.Many times,the driver is to blame.Sometimes a GPS error is responsible.Most often,says Barry Brown,it is a combination of the two.
Barry Brown is with the Mobile Life Centre in Stockholm,Sweden.He told us about an incident involving a friend who had flown to an airport in the eastern United States.There he borrowed a GPSequipped car to use during his stay.Mr Brown says,“They just plugged in an address and then set off to their destination.And,then it wasn’t until they were driving for thirty minutes that they realized they actually put in a destination back on the West Coast where they lived.They actually put their home address in.So again,the GPS is kind of ‘garbage in garbage out’.”
Mr Brown says this is a common human error,but what makes the problem worse has to do with some of the shortcomings,or failures,of GPS equipment.He says,“One problem with a lot of the GPS units is they have a very small screen and they just tell you the next turn.Because they just give you the next turn,sometimes that means that it is not really giving you the overview that you would need to know that it’s going to the wrong place.”
Mr Brown says,“One of the things that struck us,perhaps the most important thing was that you have to know what you’re doing when you use a GPS.There are these new skills that people have developed.There are these new competencies (資格) that you need to have to be able to use a GPS because they sometimes go wrong.This goes against a common belief that GPS systems are for passive drivers who lack navigational skills.”
Barry Brown says to make GPS systems better we need a better understanding of how drivers,passengers and GPS systems work together.
【小題1】According to Barry Brow,in most cases,________are blame for the problems.
A.human errors |
B.GPS errors |
C.errors caused by both drivers and GPS |
D.errors caused by putting in a wrong address |
A.GPS is nothing but garbage |
B.GPS is still not accurate enough |
C.it is difficult for drivers to use GPS equipment |
D.sometimes drivers are responsible for the problem |
A.it’s impossible to drive from the east to the west in the US |
B.Barry Brown’s friend went to Stockholm,Sweden by plane |
C.given wrong instructions,the GPS will produce wrong results |
D.GPS systems are for passive drivers who lack navigational skills |
A.It just tells the driver to turn once at a time. |
B.It gives the driver the overview. |
C.Its screen is too small to be seen clearly. |
D.It is only suitable for passive drivers. |
A.GPS systems are helpful for drivers. |
B.Driving with GPS can be difficult to navigate (導(dǎo)航). |
C.Drivers should understand how GPS systems work. |
D.Drivers should learn to use GPS systems correctly. |
