Having an exercise plan is important, but you should always ask your doctor for advice before starting it.
Keep in mind that you can have too much of a good thing: over-exercising and exercising in a wrong way can
hurt your body. The following suggestions can help you avoid this.
Warm up before exercise. This helps to prepare your body for activities. It"s especially important in the
morning.
Cool down after exercise. Rather than stop immediately, do a few gentle (轻柔的) activities to avoid aches
and pains (疼痛) later. Exercise with your limits (极限). Build up slowly. Pain is a waming, so never try to
work through it.If you don"t listen to your body, you will hurt yourself. Avoid being thirsty. Water is important
to keep your normal temperature during exercise and prevent tiredness. Wear sports shoes. These shoes can
protect your feet and prevent you from being hurt. |

Are you in shape? To find out, ask yourself some questions: Do I exercise regularly? Do I ever walk places
instead of driving my car? Do I ever play sports for fun? Do I ever take the stairs instead of the elevator? If
you answered no to any or all of the above questions, you are probably out of shape and need to start a fitness
program.
Exercise is very important. It improves your strength and blood circulation (循环). It gives you more
energy. It can help you relax and sleep well, and it can help control your weight. In fact, the U. S. Surgeon
General says that exercise can help prevent heart disease, diabetes, obesity, and osteoporosis (a disease that
weakens the bones).
The first step is to make a program. A good fitness program should be fun. It should involve (包含) both
your arms and your legs, and it should help you to build endurance(the ability to do exercise for a long time).
To make a good program for yourself, first you should think about the types of activities you like to do, what
you think you are able to do, and when you will have time to do it. A good exercise program will involve
cardiovascular activities, such as running, biking, swimming, roller skating, playing soccer or tennis, or
jumping rope. It will also involve weight-bearing exercise, such as weightlifting, and stretching activities.
Also, daily, low-intensity activities such as walking, gardening, dancing, and climbing stairs are good for your
physical health.
So what are you waiting for? Cet off of the sofa and start exercising. Sign up for yoga, tai chi, or pilates.
Join a gym or a running club, or just start walking a half an hour every day. Every little bit helps! |

In our lives, we enjoy everything from computers to cars to heated buildings. These comforts have
something in common: they all need energy to work. Energy has many different forms. One form, electricity,
comes mostly from steam-powered generators (蒸汽发电机). Steam is made by buming coal, oil, or natural
gas. Gasoline(汽油) is another form of energy. Casoline is made from oil. Oil has many other uses. Paints,
fertilizers, and plastics are made from it. We even use it to heat buildings. Coal, oil, and gas are natural
resources (资源). We take them from nature to make our lives easier.
We can classify (分类) natural resources as either renewable or nonrenewable. Coal, oil, and gas are
nonrenewable. They take millions of years to form. Some scientists predict that we will run out of oil and
gas in 50 to 100 years. Coal is more plentiful. So it may last for hundreds of years. Resources such as wood
and water are renew- able. They can be grown or recycled naturally. They can, however, become limited
from overuse.
We have developed some altemate (替代的) sources of energy. But these sources have disadvantages. For
example, hydroelectric power, or energy from running water, affects the ecology (生态) of surrounding areas.
Nuclear power (核电), another altemate source, presents the threat (威胁) of nuclear accidents. There are also
problems related to the storage (储存) of nuclear wastes. Solar and wind energies aren"t consistent. We can"t
depend on them. Geothermal energy, caused by heat from inside the earth, is tapped by drawing steam and
hot water from pools and geysers. This energy source, like most others, isn"t fully developed.
It"s time to get serious about energy. We must find practical, alternate energy sources. If we wait too long,
it will be too late. We will run out of coal, oil, and natural gas. Then we won"t have the resources to make
altemate energy sources. |
1. Does oil have many uses?
________________________________________
2. How long may coal last according to the passage?

3. Why are wood and water renewable resources?

Jeanne Calment took up skating at age 85, made her first movie appearance at age 114, and held a concert
in the neighborhood on her 121st birthday.
When it comes to long life, Jeanne Calment is the world" s recordholder. She lived to the ripe old age of
122. So is 122 the upper limit (限制) to the human life span (寿命)? If scientists come up with some sort of
pill or diet that would slow aging, could we possibly make it to 150-or beyond?
Researchers don"t entirely agree on the answers."Calment lived to 122, so it wouldn"t surprise me if
someone alive today reaches 130 or 135," says Jerry Shay at the University of Texas.
Steve Austad at the University of Texas agrees. "People can live longer than we think," he says. "Experts
used to say that humans couldn"t live past 110. When Calment blew past that age, they raised the number to
120. So why can"t we go higher?"
The trouble with guessing how old people can live to be is that it" s all just guessing."Anyone can make up
a number," says Rich Miller at the University of Michigan. " Usually the scientist who picks the highest number
gets his name in Time magazine.
Won"t new anti-aging techniques keep us alive for centuries? Any cure, says Miller, for aging would
probably keep most of us living until about 120. Researchers are working on treatments that make the life
span of mice longer by 50 percent at most. So, if the average (平均) human life span is about 80 years, says
Miller, " adding another 50 percent would get you to 120."
So what can we leam from this little disagreement among the researchers? That life span is flexible (有弹
性的), but there is a limit, says George Martin of the University of Washington. "We can get flies to live 50
percent longer," he says. " But a fly"s never going to live 150 years." Of course, if you became a new species
(物种), one that ages at a slower speed, that would be a different story, he adds.
Does Martin really believe that humans could evolve (进化) their way to longer life?"It" s pretty cool to
think about." He says with a smile. |

Some people think that they have an answer to the problems of automobile crowding and pollution in large
cities. Their answer is the bicycle, or bike.
In a great many cities, hundreds of people ride bicycles to work every day. In New York City, some bike
riders have even formed a group called "Bike for a Better City". They claim that if more people rode bicycles
to work there would be fewer automobiles in the downtown section of the city and therefore less dirty air
from car engines.
For several years this group has been trying to get the city government to help bicycle riders. For example,
they want the city to paint special lanes-for bicycles only-on some of the main streets, because when bicycle
riders must use the same lanes as cars, there may be accidents. "Bike for Better City" feels that if there were
special lanes, more people would use bikes.
But no bicycle lanes have been painted yet. Not everyone thinks it is a good idea. Taxi drivers don"t like the
idea-they say it will slow traffic. Some store owners on the main streets don"t like the idea-they say that if there
is less traffic, they will have less business. And most people live too far from downtown to travel by bike.
The city government has not yet decided what to do. It wants to keep everyone happy. On weekends,
Central Park-the largest open place in New York-is closed to cars, and the roads may be used by bicycles only.
But "Bike for a Better City" says that this is not enough and keeps fighting to get bicycle lanes downtown. Until
that happens, the safest place to bicycles may be in the park. |

| 3. No bicycle lanes have been painted yet because _____. |
A. the idea hasn"t been accepted by all
B. the main streets are not wide enough
C. the city government can"t help to paint the lanes
D. there"s no need for most people to travel by bike |
| 4. This passage is mainly about _____. |
A. city problems and "Bike for a Better City"
B. "Bike for a Better City" and the city government
C. the government"s idea on traffic and city pollution
D. a suggestion on the city problems of traffic and pollution |

Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains,
in the waves, or on the grassland, you should make it clear that your choice of sports might have great
influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside,
but also tons of water. Besides, all kinds of chemicals and a great deal of energy are used to keep its fields
in good condition. This causes environmental problems. For example, in the dry areas of Portugal and Spain,
golf is often the cause of serious water shortage in some places.
There are many environment-friendly sports. Power walking is one of them that you could take up today.
You don"t need any special equipment except a good pair of shoes; and your don"t have to worry about
resources (资源) and you purse. Simple and free, power walking can also keep you fit. If you walk very
often, it will be good for your heart and bones. Experts (专家) say that 20 minutes of power walking daily
can make you feel less nervous, sleep well and have better weight control.
Whatever sport you take up,you can make it greener by using environment-friendly equipment and buying
products made from recycled materials (再生材料). But the final purpose should be "green gyms". Compared
with traditional health clubs and modern sports centers, they are better choices. Members of green gyms play
sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your
membership. And best of all, it"s free. |
| 1. Which of the following sports is environment-friendly? |
A. Swimming in a health club.
B. Playing football on the sports field.
C. Bicycle-riding in the countryside.
D. Playing volleyball in a sports center. |
| 2. Which statement about power walking is TRUE? |
A. It needs special shoes.
B. It"s very simple but costs a lot.
C. It makes you worry about resources.
D. It"s good for health and the environment. |
| 3. The writer writes the passage in order to _____. |
A. show us how different sports help us
B. encourage us to take up green sports
C. introduce some environment-friendly sports
D. tell us how sports influence the environment |
