Jurassic Park could become a reality with dinosaurs making a comeback after a discovery last week. Scientists found remains of a dinosaur’s blood vessels(血管)and cells .In theory, DNA from these cells could be used to clone the longdead dinosaur.
A team from North Carolina State University found the remains in a fossil(化石)of the leg bone of a Tyrannosaurus rex(暴龙)in Montana, US.
The last dinosaurs on Earth died some 65 million years ago, but they left bits of themselves behind wherever they lived. Around the world ,dug-up bones and fossils have given scientists many ideas about what the animals were like.
Preserved by minerals, the newly discovered leg bone was hard. So the scientists used a liquid to dissolve(溶解)the minerals. A week later, the remaining material was soft and stretchy(有弹性的),which surprised the researchers.
Some of the materials appeared to be a network of blood vessels. Out of these, the researchers were able to squeeze(挤出)tiny , round, dark-red and deep-brown structures that seemed to be ancient blood cells.
Scientists are overjoyed by this discovery because most fossils come from hard body parts, like bones and shells, which last a long time. Soft tissues, like skin, muscle, and organs are very hard to find because they tend to break down more quickly.
Scientists think that the new discovery will help them to better understand how fossils form. Future finds should also help flesh out how the dinosaurs lived.
They were also very excited by the possibility of having some dinosaur DNA.From that scientists could create a real life “Jurassic Park”.
In the Hollywood movie, scientists reproduced dinosaurs from the DNA they found in a mosquito fossil and disaster soon followed.Scientists are excited _________________________ .

Paris is the capital of France, a country in the west of Europe. It is also one of the most beautiful and most famous cities in the world.
Paris is called the City of Light. It is also an international fashion center. What modern women are wearing in Paris will soon be worn by many women in other parts of the world. Paris is also a famous world center of education. For instance, the headquarters of UNESCO, the United Nations Educational, Scientific, and Cultural Organization, is in Paris.
The Seine River divides the city into two parts. Thirty-two bridges cross this scenic river. The oldest and perhaps most well-known is the Pont Neuf, which was built in the sixteenth century. The Sorbonne, a famous university, is located on the Left Bank (south side) of the river. The beautiful white church Sacre Coeur lies on top of the hill called Montmartre on the Right Bank (north bank) of the Seine.
There are many other famous places in Paris, such as the famous museum the Louvre as well as the cathedral of Notre Dame. However, the most famous landmark in this city must be the Eiffel Tower. Paris is named after a group of people called the Parisii. They built a small village on an island in the middle of the Seine River about two thousand years ago. This island, called the le de la Cite, is where Notre Dame is located. Today around eight million people live in the Paris area.

Whether you’re taking a trip alone or with your family, it’s easier to get sick when you’re in a new place because your body hasn’t had a chance to adjust to the food, water, and air in a new environment. Read the following tips on keeping your travel experience as healthy as possible.
Safe foods and drinks
What foods are safe to eat? Foods that have been boiled are generally safe, as well as fruits and vegetables that have to be peeled before eating. Avoid eating uncooked or undercooked meat.
Stay away from foods that require a lot of handling before serving.
Drink only bottled water when traveling. If you have to use the tap water, you should boil it first.
You can take it with you
When you’re packing, taking some painkiller and diarrhea medicine is a good idea. It’s also a good idea to pack some allergy (过敏) medicine even if you don’t take it at home, because people sometimes unexpectedly develop allergic reactions in a new environment.
Write it all down
Before you leave your sweet home, create a medical history form that includes the following information:
your name, address, and home phone number as well as a parent’s daytime phone number
your blood typea list of any ongoing health problems, such as heart disease, diabetes, or AIDS a list of current medicines you are taking a list of allergies to medicine, food, insects, and animals the name, address, and phone number of a relative other than your parent It also helps if you have some basic emergency medical knowledge, not only for yourself but also for helping others you may be traveling with. A great way to prepare for your trip is to take a first-
aid or basic life support course before you go; if you’re traveling with a group, you should know where the first-aid kit is and what’s in it.

Last week, I was invited to a doctor’s meeting at the Ruth Hospital. In one of the rooms a patient, an old man, got up from his bed and moved slowly towards me. I could see that he hadn’t long to live, but he came up to me and placed his right foot close to mine on the floor.
“Frank!” I cried in surprise. He couldn’t answer, as I knew, but he tried to smile, all the time keeping his foot close to mine.
My thoughts raced back more than thirty years - to the dark days of 1941, when I was a student in London. The scene was an air-raid shelter (防空洞), in which I and about a hundred other people slept every night. Among them were Mrs West and her son Frank, who lived nearby. Sharing wartime problems, we got to know each other very well. Frank interested me because he was not normal. He had never been normal, ever since he was born. His mother told me he was 37 then, but he had less of a mind than a baby has. Mrs West, then about 75, was a strong, able woman, as she had to be, of course, because Frank depended on her completely. He needed all the attention of a baby.
One night a policeman came into our shelter and told Mrs West that her house had been all destroyed. That wasn’t quite true, because the Wests went on living there for quite some time. But they certainly lost nearly everything they owned.
When that kind of thing happened, the rest of us helped the unlucky ones. So before we separated that morning, I stood beside Frank and measured my right foot against his.
They were about the same size. That night, then, I took a spare pair of shoes to the shelter for Frank. As soon as he saw me, he came running - and paced his right foot against mine. After that, he always greeted me in the same way. How did the writer know that the patient was Frank?
A.He was told that Frank was in the hospital. | B.He was invited to study Frank’s illness. |
C.Frank’s name was written on the door. | D.Frank greeted him in a special way. |
When and where did the writer first meet Frank?
A.In Mrs West’s house in 1941. |
B.In an air-raid shelter during the war. |
C.At the Ruth Hospital about ten years ago. |
D.In London after he Wests’ house was destroyed. |
The unlucky ones mentioned by the doctor were ______.
A.those who suffered from illness | B.those who slept in the air-raid shelter |
C.those who were killed during the war | D.those whose homes were destroyed in air-raids |
The writer placed his foot against Frank’s before he left the shelter ______.
A.to be friendly towards Frank |
B.to see if Frank’s feet were normal |
C.to find out if Frank could put on his shoes |
D.to teach Frank to greet peop![]() |
In 1901, H.G. Wells, an English writer, wrote a book describing a trip to the moon. When the explorers landed on the moon, they discovered that the moon was full of underground cities. They expressed their surprise to the “moon people” they met. In turn, the “moon people” expressed their surprise. “Why,” they asked. “are you travelling to outer space when you don’t even use your inner space?”
H.G. Wells could only imagine travel to the moon. In 1969, human beings really did land on the moon. People today know that there are no underground cities on the moon. However, the question that the “moon people” asked is still an interesting one. A growing number of scientists are seriously thinking about it. Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The “Chunnel”, a tunnel (隧道) connecting England and France, is now complete.
But what about underground cities? Japan’s Taisei Corporation is designing a network of underground systems called “Alice Cities”. The designers imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on. A solar dome (太阳能穹顶) would cover the whole city. Supporters of underground development say that building down rather than building up is a good way to use the earth’s space. The surface, they say, can be used for farms, parks, gardens, and wilderness. H.G. Wells’ “moon people” would agree. Would you? The explorers in H.G. Wells’ story were surprised to find that the “moon people” ______.
A.understood their language | B.knew so much about the earth |
C.lived in so many underground cities | D.were ahead of them in space technology |
What does the underlined word “it” (paragraph2) refer to?
A.Travelling to outer space. | B.Using the earth’s inner space. |
C.Meeting the “moon people” again | D.Discovering the moon’s inner space |
What sort of underground systems are already here with us?
A.Offices, shopping areas, power stations. | B.Tunnels, car parks, shopping areas. |
C.Gardens, car parks, power stations. | D.Tunnels, gardens, offices. |
What would be the best title for the text?
A.Alice Cities - Cities of the Future | B.Space Travel with H.G. Wells |
C.Enjoy Living Underground | D.Building Down, No![]() |
Recently a man came to me, because he was told that there is fluid(积液) around his heart. After trying many drugs which were of no use to reduce the fluid, the doctor told him the only other choice was to have an operation. He refused because he knew that every illness has a mental cause and that if he had the operation but did not clear the mental cause, the fluid would return. At last, he searched the Internet to find a metaphysical healer(玄学治疗师), and he found me.
The mental cause of his disease was an experience of breaking up five years ago with several friends, whom he had known for over twenty years. This experience broke his heart. Not knowing how to “mend” his broken heart, his body created a “repair” by surrounding his heart with fluid to protect it from the sad feelings.
Our work focused on reminding him of the feelings of being loved and forgiving his friends. Months later, his hearts was mended and the fluid disappeared. He left my office after the final session with a smile on his face and a spring in his step.
The key is: to create a healthy body, you must be healthy not only in body, but also in mind.
To be mentally healthy, you need to build up strong relationships. Creating strong relationships will insure that you are accompanied by a network of loving persons. It is important for building a support system that lifts your spirits. Even when you are alone, you will not feel lonely or upset. Strong relationships are not spaceships——they are not hard to build. In order to cure his illness, which of the following ways did the patient try?
taking many medicines having an operation
seeing a metaphysical healer visiting different doctors
A. | B. | C. | D. |
The underlined word “It” in Paragraph5 refers to “________”.
A.a mentally healthy body | B.a repaired heart |

What is the main idea of the passage?
A.Loving others will keep you in good spirits. |
B.Heart illness can be cured without operation. |
C.Creating strong relationships will keep you healthy. |
D.Spiritual health is necessary for physical health. |
Which of the following views may the writer agree to?
A.Old friendship is easy to lose. | B.A good friendship is a useful medicine |
C.The best doctor is your own body | D.It needs many efforts to build relationships |
