The meal you eat after exercising matters! No matter what time of day you exercise, the key is to follow the exercise up with meals that supply enough nutrition. For the best results, eat within thirty to sixty minutes after exercising, when the muscles are at the best time to take in nutrients.

     Here are some ideas for meals after exercising.

Home-made sports-recovery drink

     Mix banana, milk, and yogurt to make a fresh and satisfying sports-recovery drink. Dairy products like milk and yogurt work double duty, providing both protein and carbohydrates (碳水化合物). A cup of coffee, on the other hand, is a poor choice.

Protein-packed sandwich

     You can't go wrong with a sandwich after exercising－it's got everything in a hand-held package. Sandwiches provide the salt you need to replace what you have lost by sweating, while the tomatoes in them supply plenty of Vitamin C. Try using whole-wheat bread to give yourself more fiber. The cheese and fresh vegetables in sandwiches are also great for helping tired muscles recover.

Power breakfast

     An egg sandwich is a perfect post-exercise breakfast. There's protein in both the yolk (蛋黄) and the white of the egg. This recipe increases your protein intake while keeping calories and fat under control. Eggs also contain zinc (锌), which helps protect against disease.

Plant-based protein

     Beans are an amazing source of plant-based protein and carbohydrates. Make a large bowl of bean salad in the beginning of a week, and you'll have a great post-exercise meal that's ready whenever you need it

Why does the author advise eating a protein-packed sandwich after exercising?

     A. It helps increase the protein in your body.

 B. It has plenty of fat and calories

     C. The things in it help you recover.

     D. It is an amazing source of carbohydrates.

What should you do when your muscles feel tired?

A. Eat cheese and fresh vegetables.

     B. Drink as much milk and yogurt as possible.

When I come across a good essay in reading newspapers,I am often inclined to cut and keep it.But just as I am about to do so I find the article on the opposite side is as much interesting.It may be a discussion of the way to keep in good health,or advice about how to behave and conduct oneself in society.If I cut the front essay,the opposite one is bound to suffer damage,leaving out half of it or keeping the text without the subject.As a result,the scissors would stay before they start,or halfway done when I find out the regretful consequence that inevitably(不可避免地) causes my repentance.   

Sometimes two things are to be done at the same time,both deserving your attention.You can only take up one of them,the other has to wait or be given up.But you know the future is unpredictable—the changed situation may not allow you to do what is left behind.Thus you are caught in a fix and feel sad.How come that nice opportunities and brilliant ideas should gather around all at once?It may happen that your life changes dramatically on your preference of one alternative to the other.

In fact that is what life is like:we are often faced with the two opposite aspects of a thing which are both desirable like newspaper cutting.It often occurs that our attention is drawn to one thing only after we are engaged in another.The former may be more important than the latter and give rise to a divided mind.I still remember a philosopher’s remarks:“When one door shuts,another opens in life.” So a casual or passive choice may not be a bad one.

Whatever we do in our lifetime,wherever life’s storm tosses us,there must be something we can achieve,some shore we can land,that opens up new vistas to us.Don’t forget God always keeps an alternative door open for every one.While the front door is closed,there must be another open for you.

When the writer finds a good article in reading newspapers,______.

A.he is always glad to cut and keep it

B.he is always hesitant to cut and keep it

C.he often has a desire to cut and keep it

D.he often finds it difficult to decide which side to cut and keep

The writer feels regretful because______.

A.he fails to choose a good essay

B.he fails to cut the two essays on both sides well

C.he finds the essay on the opposite side is better

D.he finds that he just keeps the text without the subject

A.You’re trapped in a trouble.

B.You find it difficult to fix something.

C.You are trapped in a situation where you can’t decide which choice is better.

D.You have so many opportunities that you don’t know which to choose.

Which one do you think is the best title of this passage?

COOL INVENTIONS

From school to band Practice, the Venturi Eclectic is an Earth-friendly way to get Where you want to go. This battery-powered, zero-emission (meaning it doesn't pollute the air) vehicle runs mainly on renewable energy. Solar panels on the Eclectic's roof absorb sun rays when you're driving. On windy days, you can connect a machine to the car's roof that collects energy from the wind while you're parked. The Eclectic's top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged. Zipping (迅速行进) around the neighborhood has never been better.

Here's an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock's tank (箱) with water, add some lemon juice, and the clock will display the time without the need for environmentally harmful batteries. There are two sets of metal electrodes (电极) inside the water tank. Water contains ions (离子) that carry negative and positive charges. These ions complete a charge between the electrodes, creating enough energy to power the clock. Just refill the tank every few weeks, and this clock will keep on ticking.

Bloodhound SuperSonic Car (SSC) will be the first car to attempt to break the l,000-mile-an-hour barrier. (The current record is 763 miles an hour.) A concept for now, the rocket-shaped car gets its initial push to 350 miles an hour from a jet engine. Then a rocket fires up, pushing the SSC past 1,000 miles an hour. In order to keep the car streamlined (流线型的), the driver lies back at a 45-degree angle.

You're having a blast at your friend's birthday party. But when it's time to bring out the cake, everyone crowds around, blocking your view. No worries. Throw the Triops into the air, and this clever camera captures the view from above. The Triops can take three pictures at once, each from different angles. You can also record sounds and command the Triops to start shooting whenever it hears that noise. That's one smart camera.

Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US.

When 40 per cent of Hawaii's US$14 million-a-year papaya (木瓜)industry was destroyed by a virus five years ago, work began on creating genetically engineered (转基因的) trees.

Researchers successfully introduced seeds that were designed to resist the virus. Since then, more and more people have been testing genetically engineered trees.

Some researchers put special bacteria into trees to help them grow faster and produce better wood. Others are trying to create trees that can clean polluted soil.

Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper.

The Pentagon (五角大楼) even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack.

So far, the poplar, eucalyptus (杨树与桉树), apple and coffee trees are among those being engineered. All this can be done today because we have a better understanding of tree genomes (基因组).

However, some people fear that the genetically engineered trees will cause dangerous results. They are worried that the new trees will breed with natural species and change the balance of the forest environment.

"It could be destructive," said Jim Diamond, an environmentalist. "Trees are what is left of our natural environment and home to many endangered species."

But researchers insist that science could give nature a fighting chance against both natural and man-made dangers.

They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled.

Which kind of tree is not the ones that scientists are planting in the US?

A. Trees that worms can't hurt.

B. Trees that can protect themselves at a chemical attack.

C. Trees that can resist wind better.

D. Genetically engineered trees.

What caused the American scientists to work on special trees?

A. They think science could give nature a fighting chance against both natural and        man-made dangers.

B. Great numbers of trees have been lost due to attacks by viruses.

C. Researchers successfully introduced seeds designed to resist the virus.

D. Tree genomes are mapped out so scientists know how to improve trees.

Which of the following was probably the first kind of trees being engineered?

A. Papaya.                    B. Pine.                 C. Apple.                      D. Poplar.

Why did critics think engineered trees dangerous? Because _______.

A. these trees can destroy the balance of nature

B. everything except trees has been genetically engineered

C. trees are home to many endangered species

D. these trees may affect normal trees
