题目内容

When people lose legs after accidents or illnesses, emergency care and artificial limbs（假肢）often allow them to walk again. Newts （蝾螈） in the same situation, on the other hand, can grow limbs back on their own! Scientists have known for a long time that certain animals can re-grow limbs, but they haven’t quite figured out how these creatures do it.

Researchers have now come up with some new ideas. Their work may give people the ability to re-grow lost limbs. The researchers started with two simple experiments：when you cut a newt’s leg at the ankle, only the foot grows back；when you cut off a leg at the very end, the whole leg grows back. In both cases, the re-growth begins with stem cells. Stem cells can develop into nearly any type of cell in the body.

How do a newt’s stem cells know when to grow only a foot and when to re-grow a whole leg?

This question relates to another mystery. In newt’s, a cut-off leg will grow back only if the nerve bundle（神经束）in it also grows back , but if something prevents the nerve bundle from growing, the stem cells at the wound won’t re-grow a new leg.

In its study, a British team focused on a protein called n-AG. When the team prevented nerves in a limb from growing, but added the n-AG protein to stem cells in the limb, the limb still re-grew. That protein seems to guide limb re-growth. People have proteins that are similar to n-AG. Further research into these materials may someday help human limbs recover by themselves.

40. In the experiments, the researchers cut off a newt’s foot or leg to find out _____.

A. what stem cells were B. whether they would grow back

C. how long it would take to re-grow D. how they would re-grow

41. A newt will re-grow its leg if _____.

A. its ankle was cut off but the nerve bundle was good

B. its leg was cut off and the nerve bundle stopped growing

C. its leg was cut off and the nerve bundle could grow back

D. its ankle and the nerve bundle were cut off

42. What do the underlined words “these materials” refer to?

A. Nerve bundles and proteins. B. Proteins similar to n-AG.

C. Stem cells and proteins. D. Stem cells and nerve bundles.

43. The first sentence of the passage _____.

A. acts as a lead–in B. shows where researchers got their new ideas

C. states the author’s opinion D. describes the result of researchers’ studies

In the last 500 years, nothing about people — their clothes, ideas, or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree(可可树)by South American. Indians. The Spanish introduced it to the rest of the world during the 1500’s. And although it was very expensive, it quickly became fashionable. In London, shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600, the Spanish brought it from Peru to Europe, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the "Potato Famine (饥荒)" of 1845—1846, and thousands more were forced to leave their homeland and move to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world’s largest grower of coffee, and coffee is an important crop in Colombia and other South American countries. But it is native to Ethiopia, a country in Africa. It was first made into a drink by Arabs during the 1400’s.
according to an. Arabic legend, coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee, bush. He tried one and experienced the " wide-awake" feeling that one third of the world’s population now starts the day with.

Tui Na and Your Emotional Health

In Traditional Chinese Medicine the body, mind and spirit cannot be divided and so the unique whole-body treatment in Tui Na can also be a useful treatment correcting any imbalances in the body's energy before symptoms and disease can develop. It also works to restore emotional harmony as well as physical health. This is why after a Tui Na treatment many people "feel good". Many people in China use Tui Na regularly to keep healthy and to deal with some specific illnesses.

Tui Na is performed on the clothed body and the patient is either lying on a couch or sitting on a chair. Therapists using a variety of strokes or movements will control the intensity and direction of pressure in an exact way. The unique rolling movement in Tui Na is one of the most difficult strokes to learn and students have to practice sometimes for many months on a rice bag before they are allowed to practice on the human body.

Stress

Tui Na is of course very useful for treating stress.

It distributes the energy around the whole body. It is believed that Tui Na moves the strong energy in the tense muscles to the weaker areas, thus making a more balanced body. When your Qi （energy in the body） flow is balanced you feel relaxed and comfortable. Tui Na is especially useful for stiff shoulders and tense neck muscles.

Emotions

In Traditional Chinese Medicine each major organ is linked to an emotion. By balancing the energy in the organ, the relevant emotion will be calmed. When your emotions are out of control, you would usually turn to your doctor or perhaps a psychotherapist. But perhaps some people would not like to be seeing a psychotherapist or feel nervous about discussing their problems with others. With Tui Na one does not need to tell the therapist anything one does not want to. The treatment of Tui Na can deal with the problem itself — although if one does need to talk, then the safe space is there to do so. An active dialogue between the therapist and the patient will help to get a better effect.

How the major organs rule your emotions

Each major organ — the heart, the stomach, the spleen, the liver, the bladder, the kidneys, the lungs, etc. — is linked to a relevant emotion.

The heart is linked to joy, excitement and sadness. If the heart is out of balance, the patient may dream a lot at night and often forget something important in the day.

The stomach and spleen are connected with too much thinking or worrying — over anxiety. When the stomach is out of balance there is often a lack of energy. The patient often feels very tired and has no interest in doing anything at all.

The liver and gall bladder are linked to anger. In Chinese Medicine the eyes are connected with the liver, and many people who suffer from anger often suffer from eye problems. The gall bladder rules decision-making and too much energy here can lead to rashness, while if there is too little it can bring about indecision. Where there is a history of depression, the therapist would look to the liver.

The bladder and kidneys are linked to fear of all kinds, from simple anxieties and phobias to vague fears and worries.

The lungs are connected with feelings of grief and sadness. When there is a history of grief, the therapist would look to the lungs.

Tui Na is used in almost all the hospitals in China and very popular among Chinese people. It is a useful and valuable method of restoring Qi balance, when emotional and physical health is out of balance. Tui Na is one of the remaining secrets of Chinese Medicine.

1. According to the passage, which statement is TRUE about Tui Na?

A. Tui Na is a whole-body treatment and can't be divided into different parts.

B. Tui Na can be used to balance the diseases before they can develop in the body.

C. Tui Na can bring back not only physical health but also emotional health.

D. Tui Na only makes people "feel good" but do not actually cure disease.

2. How can the emotion be calmed?

A. By linking the organ to an emotion.

B. By telling the therapist anything one does not want to.

C. By discussing their problems with others.

D. By balancing the energy in the relevant organ.

3. When the stomach is out of balance, .

A. the patient will have a stomachache

B. the patient will have a lot to worry about

C. the patient will have nothing to do

D. the patient will not feel like doing anything

I hated dinner parties .But I decided to give them another shot because I’m in London. And my friend Mallery invited me . And because dinner parties in London are very different from those in New York, “I’m having a dinner party ” means : “I’m booking a table for 12 at a restaurant you can’t afford ang we’ll be sharing the cheque evenly , no matter what you eat.” Wors , in Manhattan there is always someone who leaves before the bill arrives .They’ll throw down cash, half of what they owe, and then people like me, who don’t drink, end up paying even more . But if try to use the same trick , the hostess will shout; “Where are you going ?” And it’s not like I can say I have somewhere to go : everyone knows I have nowhere to go.

But in London, dinner patise are in people’s homes . Not only that, the guests are an interesting mix .The last time I went to one , the guests were from France , India ,Denmark and Nigeria; it was like a gathering at the United Nations . In New York ,the mix is less striking . It’s like a gathering at Bloomingdat="le’s" , a well-known de partment store.

For New Yorkers, talking ,talking about other parts of the world means Brooklyn and Queens in New Yorkers.But at Mallery’s ,when I side that I had been to Myanmar recently, peo ple knew where it was , In New Yorkers people would think it was a usual culb.

More than seven hundred years ago, the Prince of Wales had a very big and brave dog called Gelert. One day the Prince wanted to go hunt-ing with his men. He told his dog to stay at home and look after his baby son. The baby was in a wooden cradle, which was like a small bed. When the Prince came back from hunt-ing, Gelert ran out to meet his master. He wagged his tail and jumped up to put his paws on the Prince's chest. Then the Prince saw the blood on Gelert's jaws and head.
