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. |

Like most people, you"ve probably never given your blood glucose (糖) a second thought, unless you have
diabetes (糖尿病). But researchers now know that whether or not you have diabetes, eating too much can
make your blood glucose go up and down and can increase the danger of heart disease. It may be even bad for
your memory.
This realization has greatly changed the way we understand food and health. Luckily, none of these things
happen ovemight, and even small changes in the food you eat every day can start you on a healthier path.
When you are hungry, do you reach for a chocolate cake or a box of biscuits? These "fast-acting" foods
are handy and they take no time at all to dissolve (溶化) in your stomach. Then they race into your blood,
running through your body with blood glucose. The trouble is the comfort doesn"t last long, leaving you feeling
hungry again. As a result, your blood glucose will run out of control.
It"s no wonder most of us have less energy than we"d like and feel tired too often. It"s also no wonder that
most of us weigh more than we want to. Yes, eating too much and exercising too liLtle are main reasons, and
ever changing blood glucose will send you shopping for bigger jeans.
For most of us even when our blood glucose goes up and down after a large meal, our body can bring it
back to normal in a few hours. Only people with untreated diabetes have blood glucose levels that stay quite
high most of the time.
For a long time, doctors thought that only these people needed to take care of their blood glucose levels.
Now, we know that even in healthy people, high levels after meals can damage (损坏) the body, even if it
never causes diabetes. |
| 1. How does our blood glucose change after a large meal? |
A. It remains unchanged.
B. It stays on high levels.
C. It goes up and down.
D. It comes back to normal. |
| 2. What does the writer think of "fast-acting" foods? |
A. He thinks they are delicious.
B. He thinks they are easy to get.
C. He thinks they make us healthy.
D. He thinks they damage our body. |
| 3. What shall we do if we want to keep the normal blood glucose? |
A. Check our blood glucose after each meal.
B. Have proper food and exercise every day.
C. Eat certain kind of medicine before meals.
D. Ask the doctor for help from time to time. |

Not all memories are sweet. Some people spend all their lives trying to forget bad experiences. Wars and
traffic accidents can leave people with terrible physical and emotional (精神上的) hurts. Often they appear
again in dreams.
Now American researchers think they are close to developing a drug which will help people forget bad
memories. The drug is designed to he taken immediately after a frightening experience. They hope it might
reduce or possibly erase (清除) the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body producing
chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects
of memories may be reduced, not all the memories are erased.
The research has caused a great deal of argument. Some think it is a bad idea, while others support it.
Supporters say it could lead to drugs that prevent or treat soldiers" troubling memories after war. They
say that there are many people who suffer from terrihle memories.
"Some memories can ruin (毁坏) people"s lives. They come back to you when you don"t want to have
them in a dream. They usually come with very painful emotions," said Roger Pitman, a professor of psychiatry
at Harvard Medical School. "This could reduce a lot of that suffering."
But those who are against the research say that changing memories is very dangerous because memories
give us our identity (特质). They also help us all avoid the mistakes of the past."
All of us can think of bad experiences in our lives that were horrible at the time but make us who we are.
I"m not sure we want to erase those memories," said Rebecca Dresser, a medical ethicist. |
| 1. Now American researchers are trying to develop a drug to _______. |
A. change people"s bad memories into good ones
B. make people forget what happened in the past
C. help soldiers get away from troubling memories
D. treat people who suffer from terrible memories |
| 2. The drug that have been tested on people can _______. |
A. cause the brain to lose memories
B. reduce the effect of bad memories
C. help people improve their memories
D. totally erase the painful memories |
| 3. Rebecca Dresser thinks that _______. |
A. some memories can ruin people"s lives
B. the drug can prevent people from sufferings
C. bad memories make us different from others
D. taking the drug will do harm to people"s health |

We need to be responsible for our environment. Being a frugal consumer (节俭的消费者) is one way
to help. But, what exactly does that mean?
Use It Up
You can use things up instead of wasting them. Squeeze that last bit of toothpaste out of the tube. Use
the last little piece of soap. Don"t throw away any bits of the biscuit at the bottom of the box.
Wear It Out
You do not always need to have new things. Suppose your sneakers have broken laces, but they still
fit you. Repair them and wear them longer. You don"t have the latest iPhone until the old one doesn"t work
anymore. Then you can get a new one. Think twice before replacing something that still works.
Make It Do
When something you want is not on hand, look for something else that you already have to take its place.
Suppose you are packing your lunch for tomorrow and want a butter sandwich. You are out of butter. Have
a cheese sandwich instead so that you can use all of the cheese. Learn to fix broken toys instead of just
throwing them away. With a little thought, you can make something do, instead of buying something new.
Do Without
Think about all those things that you would like to have. Do you really need them? How long will you
really play with that new toy you saw on TV? Making the things that we want uses up your world"s resources(资源). And, getting rid of the things we don"t want any more takes up even more resources and space. |

to make different kinds of foods. Some of them can make the food more delicious and some of them can
make it colorful. But lots of chemicals are used to produce what we eat every day.
Sudan red is a kind of chemical that factories used it to dye cloth, make the shoes brighter. But some
people produced salted duck eggs with it. However, it isn"t a kind of food additive. The food made from
Sudan red makes it easier to cause cancer. Melamine (三聚氰胺) is another kind of chemical that are banned
(禁止). It"s white crystal (晶体), which was discovered by a German chemist called Sustus Von Liebig in
1834. Melamine can be used to make paper, medicine and woods, ect. But nobody can imagine that some
people used it as a material of milk powder (粉末). Because of melamine, it"s reported that 4 babies died and
more than 50 thousand babies are affected since 2008. Sanlu, a famous milk powder factory was closed.
What"s worse, milk powder with melamine appeared in 2011 again. Problems of food safety, for example,
poisonous rice, lean meat powder (瘦肉精) and plasticizers (塑化剂) are becoming more and more serious.
Fortunately, lots of laws have been made to make the solution (解决方法) better. We think we will eat
more healthily in the future. | 1. Can the food additives make the food colorful and more delicious?
