If mans best friend is a dog， then who is a dogs best friend？ That would be Rover， Glow， Ivan or Raina. They recently donated （捐贈） blood to other dogs. And they did it without having to travel far from home： they visited an animal bloodmobile.

Like the Red Cross vehicles for humans， the University of Pennsylvanias traveling vet lab goes to where the donors are to make it easier to give. The bloodmobile makes weekly rounds through Philadelphia and New Jersey.

Like humans， not every dog is qualified （合格的） to donate blood. The dogs are examined for health first. Dogs must have the correct blood type， weigh at least 55 pounds and be under 8 years old. About 150 dogs take part in the program. Each donates three or four pints （品脫） a year， which can help animals suffering from illness like cancer or an accident like being hit by a car.

Sandy Lucas brought her 7-year-old dog， Raina， to the bloodmobile last week. She said she wouldnt have taken the dog to Penn Vets animal hospital in downtown Philadelphia， which is twice as far from her home. “I was very， very excited that she had the right blood that was needed to help another dog out，” said Lucas. “Well surely do it again.”

Just like people， the donors get a snack and a heart-shaped sticker immediately after giving. Whats more， they receive dog food to take home.

If dogs are doing what they can to save other dogs， why cant we do it to save other people？ Next time you hesitate （猶豫） over whether to donate blood or not， think of the dogs.

1. Why does the writer mention Rover， Glow， Ivan and Raina in Paragraph 1？

A. They are mans best friends.

B. They are common names for dogs.

C. They get along well with other dogs.

D. They have donated blood to other dogs.

2. What do we know about the traveling vet lab？

A. It is a Red Cross vehicle.

B. It collects dogs blood for other dogs.

C. It travels through Philadelphia every day.

D. It was donated by the University of Pennsylvania.

3. What can we learn from Paragraph 4？

A. Sandy Lucas is unwilling to let her dog donate blood.

B. The bloodmobile welcomes dogs from anywhere in the city.

C. The animal bloodmobile has made it easier for dogs to donate blood.

D. Penn Vets animal hospital in downtown Philadelphia is popular.

4. Through the last paragraph， the author wants to ___ .

A. encourage us to donate blood

B. show the importance of dogs

C. compare humans with dogs

D. ask us to help dogs

British scientists have discovered the willow trees planted at an angle （角度） could increase sugars for biofuel production.

Willow is fast-growing. It is already used to produce fuels for the renewable heating and power market. In future it could also help to produce biofuel to power vehicles. It has been known that when willows growing in the wild are blown sideways they produce more sugars. But for a while it has not been known why this happens.

Researchers at Imperial College London， led by Dr Nicholas Brereton and Dr Michael Ray of the Department of Life Sciences， have now solved the mystery. When the tree is blown sideways， its genes（基因） produce large numbers of sugar molecules （分子） to straighten the tree upwards.

“This is an important breakthrough. Our study now shows that natural genetic changes are related to these differences. And this could well be the key to unlocking the future for green energy from willow，” said Dr Brereton.

The research was carried out under lab conditions. The willows were grown at an angle of 45 degrees. They were compared to willows which grow naturally straight upwards. The team then looked for the same effect among the willows growing on the Isle of Orkney where strong winds cause the trees to bend at extreme angles. They discovered that the Orkney trees produce five times the amount of sugars found in willows grown in sheltered conditions.

Willow is widely planted across the UK. The results show that biofuel crops such as willows could be grown in climatically challenging conditions where chances of growing food crops are limited.

The study is published in Biotechnology for Biofuels.

5. What may happen when willows are planted in strong winds？

A. They will stop growing.

B. Few sugars will be produced.

C. They will grow sideways.

D. Changes in genes will take place.

6. What can we learn from the passage about the Orkney willows？

A. They are unusually rich in sugars.

B. They grow naturally straight upwards.

C. They looked taller than ordinary willows.

D. They are stronger than those growing in labs.

7. Farmers living in challenging climate ___ .

A. use biofuel for heating and power

B. are encouraged to grow biofuel crops

C. should make their willows grow straight

D. can plant different kinds of food crops

8. Where does this passage probably come from？

A. A personal diary. B. A newspaper ad.

C. A scientific journal. D. A travel magazine.

A

When I looked at the grade on my math paper my jaw （下巴） almost dropped to the ground： a big “65” in bright red ink. I had never received such a terrible grade before.

I was so ashamed that when I got home that afternoon I lied to my dad. I told him I got 85 and that the report wouldnt come until the end of the month. Dad smiled. His daughter would never lie about her grade， so he didnt doubt the unusual delay （延遲） of my report.

A month later， Dad casually asked me again about the report at the dinner table. He looked right into my eyes and asked for an answer. Having no choice. I told him that I had in fact got just 65 in my math final. I had lied because I didnt want to let him down.

For a moment， he just looked at me. I would have preferred a telling off（斥責(zé)） than that silence. Finally， Dad said， in a hurt voice， “You have already let me down， with your lie. I am not disappointed at your math score. That is no big deal—no one can be perfect all the time. But I am very disappointed in you. If you cant be honest with your dad， who can you be honest with？ Its much easier to achieve a better grade than rebuild someone elses trust in you.”

Dads words touched my heart. I couldnt forgive myself for having hurt his feelings. I took out the report that I had been hiding for weeks， handed to him and apologized， sincerely. I realized that my honesty is not only important to me personally， but to those around me that truly care about me.

In one of Shakespeares plays a character says， “No legacy （遺產(chǎn)） is so rich as honesty.” After the crisis between Dad and me， I began to understand those words.

In the modern world more and more people meet the problem of identity.The most interesting example is that of a so-called “banana”， which refers to an American who has an Asian face but holds Western value.

In Shanghai， there now live a group of people from abroad. They dont look different from the locals and speak fluent Chinese or even Shanghai dialect， but when it comes to writing Chinese characters， they are almost illiterate （文盲）. Jack is such an example. He never learned to read or write Chinese characters， which he finds mysterious and difficult. “But when I am in the States， I feel thats not my home either，” he said.

At De Gaulle Airport in France， there is a Swiss man who has been living in the waiting room for a long time because he lost his passport during his travels. He was refused entry into several countries. But when he was eventually allowed to return to Switzerland， he refused to leave the airport. His reason was very simple—“I am sure who I am. I need no acknowledgement from others，” he said during an interview. For this reason he was honored by the Western media as “the Hero of identity.”

As the Internet becomes more and more popular， the problem of identity becomes more serious. In a virtual world， people can have different addresses registered with different names. In the Internet chat room， even ones gender （性別） is hard to determine.It seems that in the global village， people are saying hello every day to each other without knowing whom they are talking to.

When I was seven years old， my family made me an ant farm. First， we put clean sand in a thin glass box. Then we waited for the ants to arrive.

After the ants were in the glass farm， they started to make tunnels （隧道）. I was amazed that each one knew exactly what to do. Each had its own job.

On the fifth day a tragedy happened. I put my face so close to the glass farm that I knocked it over.

All the tunnels fell down. Although the ants remained alive after their earthquake， one by one they began to die. I was scared as I watched them give up building their tunnels to carry the bodies to a corner of the farm.

My mother said that the ants were dying of sadness. They simply could not stand that their tunnels were gone.

Although much time has passed， I still think of that ant farm. Mom had hoped it would teach me about the natural world， but it taught me much more.

Over the years， I came to realize the importance of teamwork. Working together， the ants were able to make an amazing world for themselves. I also learned that they should be admired for their hard work.

But there was an even larger lesson that I did not realize until recently： adversity （苦難） is a natural part of life， and must be accepted. Unlike the ants， we cannot give up when we are sad. We have to realize that if a tunnel is gone， we must build another.

Giving up， I say， is not a good choice.

There have never been many adventurers. But they were really businessmen. There was something they wanted—a lady， or money， or a country， or honor. And so they got it. But a true adventure is different. He starts without any special purpose. He is ready for anything he may meet.

There have been many half-adventurers. History is rich with their stories. But each of them had a special purpose. They were not followers of true adventure.

In the big city of New York， Romance and Adventure are always waiting.

We look up suddenly and see a face in a window. The face seems to interest us strangely. Or in a quiet street， we hear a cry of fear and pain coming from a house where no one lives. A car takes us to a strange door， instead of to our own. The door opens and we are asked to enter. At every corner， eyes look toward us， or hands are raised， or fingers point.

But few of us are ready to accept. We wish to do only the things that everyone else does. We move on； and some day we come to the end of a long quiet life. Then we begin to think. Then， when it is too late， we are sorry that we have never known true Romance and Adventure.
