Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically.
Diet products weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie(卡), unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the counter instead. All we have to do is to swallow or recognize the word “diet” in food brands.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.
【小题1】The first paragraph mainly tells us _____.
A.diet products can bring out people’s potential |
B.people have difficulty in choosing diet products |
C.diet products are misleading people |
D.people are fed up with diet products |
A.resist a variety of diet foods |
B.hesitate before they enjoy diet foods |
C.pay attention to their own eating habits |
D.watch their weight rather than their diet |
A.to warn people of the side effect of diet products |
B.to tell people how to lose weight |

解析试题分析:我们的生活中充斥着各种各样的减肥产品。这些产品真能帮助我们减肥吗?事实上,减肥产品不仅在身体上而且在心理上都给人们带来了危害。减肥需要坚强的决心和实际的努力锻炼,而减肥产品基本没有营养还会让人觉得减肥很简单:吃两片药片就可以。这些都告诉我们应该向减肥产品说不。
【小题1】主题归纳题。根据We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us.还有第四句中的for products that harm us可知选C(减肥产品在误导人们)。mis-leading可以拆分成两个部分,后面的意思是“导向” ,一般情况下,前面的前缀mis起相反的意思,那么就是误导了。
【小题2】细节理解题。根据第二段的第第二句话的意思可知,减肥产品在心理上削弱了我们。我们的体重有问题不在于在实际上失去了重量,而在于控制消耗脂肪,高热量,不健康的食品。选 D(注意体重而不是饮食)。
【小题3】主题归纳题。根据最后一段的意思可知,减肥产品对我们的健康有害,所以购买需谨慎。选A(警告人们减肥产品的副作用。)。
【小题4】篇章结构题。分析各段的主题大意可知,第一段是我们在关注对我们身心有害的产品;第二段介绍在心理上削弱注意力;同时说了一方面;第三段有接着提到另一方面;第四段介绍减肥产品对人的身体的危害;第五段得出结论:减肥产品有害,不应该购买。所以选B。

Surfing the Internet for fun will make you a better employee,according to an Australian study.
The University of Melbourne study shows that people who use the Internet for their own reasons at work are about 9 percent more productive than those who do not. Study author brent Coker said“Surfing the Internet at times helps increase an employee’s attention.”
“People need to relax for a bit to get back their attention,”Coker said on the university’s website.”Having a short break, such as a quick surfing of the Internet, helps the mind to rest itself,leading to a higher total Internet attention for a day’s work, and as a result, increase productivity(生产效率),”he said.
According to the study of 300 workers ,70 percent of people who use the Internet at work surf the Internet for their own reasons during office hours. Among the most popular surfing activities are searching for information about products, reading online news, playing online games and watching videos.”Firms spend a lot of money on software to block their employees from watching video, using social networking sites or shopping online, ”said Coker.”that’s not always a good idea.”
However, Coker said the study looked at people who surfed the Internet in moderation(),or were on the Internet for lee than 20 percent of their total time in the office.”Those who spend too much time surfing the Internet will have a lower productivity than those without,”he said.

One reaction to all the concern about tropical deforestation(毁林) is a blank stare that asks the question, "Since I don't live there, what does it have to do with me?"
The answer is that your way of life, wherever you live in the world, is tied to the tropics in many ways. If you live in a house, wash your hair, eat fruits and vegetables, drink soda, or drive a car, you can be certain that you are affected by the loss of tropical forests.
Biologically, we are losing the richest regions on earth when, each minute, a piece of tropical forest, the size of ten city blocks, disappears. As many as five million species of plants, animals, and insects (40 to 50 percent of all living things) live there, and are being lost faster than they can be found and described. Their loss is immeasurable.
Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial rubber is produced in Malaysia and Indonesia, while the Amazon's rubber industry produces much of the world's four million tons. And rubber is an important material in making gloves, balloons, footwear and many sporting goods. Thousands of other tropical plants are valuable for their industrial use.
Many scientists strongly believe that deforestation contributes to the greenhouse effect -- or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide into oxygen.
Carbon dioxide levels could double within the next half-century, warming the earth by as much as 4.5 degrees. The result? A partial melt-down of polar ice caps, raising sea levels as much as 24 feet; even 15 feet could threaten anyone living within 35 miles of the coast. Unbelievable? Maybe. But scientists warn that by the time we realise the severe effects of tropical deforestation, it will be 20 years too late.
Can tropical deforestation affect our everyday lives? Now, you should have got the answer.
【小题1】The underlined word "synthetics" probably means_________.
A.natural rubber | B.tropical materials |
C.man-made material | D.commercial rubber |
A.The forests are losing their function in turning carbon dioxide into oxygen. |
B.Many of our daily uses are related to the tropical forests. |
C.Tropical plants can be used to make industrial products. |
D.High carbon dioxide levels will make the earth warmer. |
A.puzzling | B.cold | C.supporting | D.opposed |
A.Tropical Forests | B.The Value of Tropical Forests |
C.Tropical Forests and Our Life | D.The Greenhouse Effects |

What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to? The good news is that we can. In fact, we are swimming in it--- literally.
Hydrogen is one of the building blocks of the universe. Our own sun is basically a big, dense cloud of the stuff. And hydrogen can be used to create electricity for power, heat and light.
The problem is that hydrogen is everywhere and nowhere at the same time. It does not exist as a material on its own, but is always part of something else. So it has to be separated before it can be used.
Most commercial hydrogen in use now is created from natural gas. As oil will start to run out in around the year 2030, it makes sense to produce as much hydrogen as possible as soon as we can. But natural gas supplies will also begin to run out soon after. Another source is needed.
Researchers are now using electricity to make water into hydrogen. Companies are working on the problem in their own areas. The first commercial hydrogen “fuel cells” for computers and mobile phones have already come on to the market. Auto companies have also invested over US $2 billion in the production of hydrogen fuelled cars.
The nations of a hydrogen fuelled planet would not fight over energy recourses. There would be a great reduction in pollution. The only by-product of creating hydrogen is pure drinking water--- something that is very scarce in many parts of the world. But that is not where the good news ends. Once the costs of producing hydrogen have been brought down, it will possibly provide power for a third of the Earth’s population that has no electricity.
And electricity creates wealth. In South Africa over the last decade there has been a large programme of electrification. Thanks to the programme, people do not have to spend their days looking firewood to burn for heat. And with electric light, they can work long into the night.
Some scientists see radical changes in the way the human race co-operates. Hydrogen creates electricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it. Late at night, a man drives home in London and connects his car into the “world-wide hydrogen web,” which it supplies with electricity. A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car. Hydrogen could be the first democratic energy source.

The fourth round of heavy smog to hit Beijing in four weeks has sent more people to the hospital with respiratory (呼吸的) illnesses and led to calls for laws to control the pollution.
Pan Shiyi, a celebrity, said he is planning to propose a Clean Air Act to the local government. As a representative to the Beijing Municipal People's Congress, he started an online survey at 9:20 a.m. Within three hours, more than 25,000 web users, or 99 percent of total respondents (应答者) , welcomed his proposal.
They have good reasons to stand alongside Pan. The latest round of haze(雾霾)reduced visibility to under 500 meters in many parts of the city. The smog has also led to a great increase in respiratory illnesses, particularly among children and the elderly. Anxious parents and doctors almost all blame the smoggy air for the illnesses. Though most schoolchildren are home for the winter holidays, the bad air can easily move indoors. Besides, ordinary medical masks fail to provide enough protection, so some people have turned to gas masks.
The causes of the frightening smog are rather mysterious, though experts blame too much emissions (排放) and the mountains around Beijing that trap pollution in winter, unless there is enough wind to clear it away. Some critics blamed China’s top two oil firms, China National Petroleum Corp and China Petrochemical Corporation, saying the companies’ outdated production technologies produce large quantities of high-polluting gas fuel.[来源:学|科|网]
Meanwhile, some Beijingers have moved their brainstorming discussion to computers. If Pan’s proposal for a Clean Air Act is adopted, netizens say the new law should include items providing for “car-free days” in times of smog, higher standards for vehicle fuel, stricter limit to industrial and engine gas emissions, and more effective protection for the public.
Beijing is not the only city that has ever lost the blue sky. Five days of thick fog caused thousands of deaths in Britain in December 1952, urging the government to pass the first Clean Air Act in 1956, which introduced smokeless zones and cleaner fuels to reduce pollution. That may provide some experience for Beijing to refer to.
【小题1】Why did Pan Shiyi started an online survey?
A.To know the public’s opinions on pollution |
B.To tell people the danger of the smoggy weather |
C.To call on people to support his proposal |
D.To collect supporting evidence for his proposal |
A.People are clear about the causes of the smoggy weather. |
B.Children staying indoors will not get respiratory illnesses. |
C.Smog is worse for people with lower resistance to diseases. |
D.Masks can give people protection against the smoggy weather. |
A.suggest Beijing should learn from other countries |
B.let people know many places have this problem |
C.tell people the situation in Britain is worse |
D.call on the government to pass Britain’s Clean Air Act |
A.The Use of Gas masks and Engines |
B.Beijingers Call for Clean Air Act |

This site , all-birds. com, is about bird watching. Enjoy your browsing. There is much to learn and see.
Bird Watching Equipment
Some items that might make bird watching more enjoyable are binoculars ( 双目望远镜) , a camera, some kind of system for keeping notes, and maybe a back pack. Birders often keep lists of the birds they see along with notes about the habits. There is some great bird log software that will let you keep records on your computer. For more details on choosing binoculars see our Binocular -Optics page.
Clothes
If you are walking through a wooded area just wear clothes you would wear on any hike or field trip. You are best off wearing clothes with dull colors that mix into the background. Greens, browns, and grays are good. Avoid fabrics that rustle(沙沙响)easily. Depending on the birds you are watching you may want to get rain gear, rubber boots and warm clothing. For birds such as owls that you might look for in the evening a strong flashlight is also handy.
Choosing a Bird Field Guide
Take a good field guide to identify birds. Look for clear color pictures that make it easy to recognize one bird from another. Next to each picture should be detailed descriptions of each bird's anatomy, habits, and what it eats. The guide should have information about what habitat each species uses. Many guides have maps showing the range of different birds along with their migration patterns.
Where and When to see Birds
Learning the habitats of birds in your area will increase the number of birds you see, and make your birding more enjoyable. If you know that Meadow larks are likely to be in open grassy areas, and dippers are forage along stream beds, you may be looking for them if you are in those types of habitats. Edge areas where different types of habitats meet will likely have more species in them. You are more likely to see specific birds at certain times of the day. For example songbirds are easier to see two to three hours after dawn, or just before sunset. This is when songbirds are most actively feeding. Many small birds will be silent or even hidden during the rest of the day. After sunup is the best time to see eagles and hawks. Visibility is best for hunting at this time, and they can soar on the thermal currents from the warmed air. Birds like owls are more likely to be seen in the evening. Many shorebirds and waders rest at high tide and feed when the water rises or falls.
Photographing Birds
Patience in Bird Photography
Most birds are afraid of people, and all species have their own comfort zone. With a little time you can learn the comfort zone of the birds you are photographing. Once they know that you are not a threat you may be able to get closer.
Type or Style
Your reason for photographing birds may determine your style and the kind of equipment you use. If you are just recording the kinds of birds you see you don't need to get as close, and you can use less expensive equipment, then you need for high quality prints.
Photographing Birds in Flight
Photographing birds in flight can be fun. Many digital cameras have a tracking function. With these you focus on the bird, and then as you track it the lens will keep focus.
Use Your Yard
Choose an open area where the birds will get direct sunlight, showing off their magnificent colors.
Try using props
Birds will often land on a stick or post near a seed feeder before going to the feeder. The background was just an out of focus fence but you can use anything you want for a background, and then wait for a bird to perch.
【小题1】The main purpose of the passage is to _____.
A.attract more people to photograph birds |
B.help birders learn how to identify and understand birds |
C.call on people to set some comfort zones for birds |
D.inform birders of the results of a scientific research on birds |
A.red | B.yellow | C.brown | D.blue |
A.Owls | B.Shorebirds | C.Songbirds | D.Larks |
A.A stick in the yard may scares birds off when you are photographing them. |
B.It will be wise for birders to hire a guide for themselves. |
C.Birders have to bring some notebooks to keep records of birds' habits. |
D.A flashlight will come in handy when you look for owls. |

Our environment isn’t as green and beautiful as it should be. There are steel monsters blocking out the sun, blowing out dangerous smoke, and letting out poisonous chemicals into rivers, cars producing harmful waste gas, people throwing out waste in a wrong way and all other kinds of sources that ruin the planet. Facing current environmental problems, people need to do their best to save the Earth.
You can see many big garbage dustbins in the streets. They’re not there for a show, but for you to drop your waste. We should realize that what a little we do does count. So next time you get that urge to throw gum or a chocolate package out of the car window, or “ accidentally” drop as you walk down the street, ask yourself how much waste you’ve been contributing to the environment with that bad habit going on for years.
At home, the first thing we can do to protect the environment is avoid letting water run continuously and make sure that taps(水龙头)are not leaky(泄露的),which would help greatly in scrimping. Another is to use energy-saving lights, and turn them off before you leave the rooms. It’s not only energy-saving, but also cuts down electricity costs.
Recycling is a method to make items reusable. Many things you want to throw out can be made into new products through the reproducing process. Use your imagination to come up with ways on things that you can use again.
Pass the message of simple ways to save the environment on to kids. Starting with kids is a good way of teaching the message early in their lives, in the hope that they can carry it forward as they grow older.
With environmental protection awareness in mind, we can do what we can, for the results are to have a big effect on the planet. As long as we do our part, the world is one small step closer to being saved.
【小题1】The underlined word “scrimping” in the third paragraph can be replaced by _____.
A.saving | B.cleaning | C.cooking | D.drinking |
A.protecting the environment begins with small chores |
B.protecting the environment should start from childhood. |
C.wonderful life comes from environmental protection |
D.protecting the environment benefits the country and the people |
A.The more people do their part, the greener the environment will be. |
B.Selling what you don’t want any more is a kind of recycling. |
C.To protect the environment may help you save some money. |
D.Your bad habits for the environment are a valuable contribution. |
A.The Use of Garbage Dustbin |
B.How to Save Water and Electricity |
C.How to Save the Environment |
D.Our Current Environmental Problems |

How to be Prepared
Electricity, water, gas and telephone may not be working after an earthquake. The police and fire department are likely to be tied up. You should be prepared to take care of yourself for at least three days, preferably for a week.
This list can also be applied to other disasters, such as floods or wildfires.
1. food and water (a gallon a day per person)
2. a first aid kit
3. a fire extinguisher suitable for all types of fires
4. flashlights, a portable radio extra batteries
5. blankets, clothes, shoes and money (ATMs may not work)
6. baby and pet food
It’s also a good idea to decide beforehand how and where your family will reunite if separated during a quake and to conduct in-home practice drills.
During an Earthquake
If you are indoors, stay there. Get under and hold onto a desk or table, or stand against an interior wall. Stay away from exterior walls, glass, heavy furniture, and stay away from windows and outside walls and do not use the elevator.
If you are outside, get into the open, stay into the open, stay away from buildings, power lines or anything else that could fall on you.
If you are driving, move the car out of traffic and stop, avoid parking under or on bridges or overpasses, Try to get clear of trees, light posts, signs and power lines.
If you are in a crowded public place, avoid panicking and do not rush for the exit. Stay low and cover your head and neck with your hands and arms.
After an Earthquake
If the phone is working, only use it in case of emergency. Likewise, avoid driving if possible to keep the streets clear for emergency vehicles.
Be aware that items may fall out of cupboards or closets when the door is opened, and also that chimneys can be weakened and fall with touch. Check for cracks and damage to the roof and foundation of your home.
Listen to the radio for important information and instructions. Remember that aftershocks, sometimes large enough to cause damage in their own right, generally follow large quakes.
If you leave home, leave a message telling friends and family your location.
