Silk production has a long and colourful history unknown to most people. Scientific discoveries have shown that silk production existed in China from around 2500 B.C., although it could be much older. For hundreds of years, China kept the secret of silk to itself as one for the most closely protected secrets in history. Anyone revealing the secret of silkworms or trying to take silkworm eggs out of ancient China was punished by death.
At one time silk was reserved only for the Chinese emperor. Gradually, others began wearing silk. In addition to being used for clothing, silk came to have industrial uses in ancient China, something that happened in the West only in modern times. Silk was used to make musical instruments, fishing lines, weapons, ropes and even paper. During the Han Dynasty silk became a form of money. Farmers paid taxes in both rice and silk. The prices of goods were calculated in lengths of silk just as they had once been calculated in gold. The importance of silk is even reflected in the Chinese language. For example, of the 5000 most common Chinese characters, around 500 have silk as their “key”.
In spite of their secrecy, the Chinese eventually lost their monopoly on silk production. It reached Korea in around 200 B.C. when immigrants from China arrived there. Silk production came to India in 300 A.D.. It was not until 500 A.D. that silk production came to Europe when travellers smuggled out silkworms in hollow tubes of bamboo. These were used to establish silk industry in Rome (modern-day Italy), although Chinese silk was still considered to be the best.
Silk was brought to Rome from China by means of the Silk Road. There were actually two Silk Roads, one over land and one on the sea. The land route in particular had a huge effect in history. All sorts of trade goods — silver, gold, jade, porcelain — passed along this road. Ideas travelled the Silk Road too. For example the religion of Buddhism was carried to China from India by traders on the Silk Road. The Silk Road created the first international culture, exposing many people to the ideas and treasures of both Western and Chinese cultures.How was China able to keep the secret of silk production?

Homestay provides English language students with the opportunity to speak English outside the classroom and the experience of being part of a British home.
What to Expect
The host will provide accommodation and meals. Rooms will be cleaned and bedcovers changed at least once a week. You will be given the house key and the host is there to offer help and advice as well as to take an interest in your physical and mental health.
Accommodation Zones
Homestays are located in London mainly in Zones 2, 3 and 4 of the transport system. Most hosts do not live in the town centre as much of central London is commercial and not residential. Zones 3 and 4 often offer larger accommodation in a less crowded area. It is very convenient to travel in London by underground.
Meal Plans Available
♢Continental Breakfast
♢Breakfast and Dinner
♢Breakfast, Packed Lunch and Dinner
It’s important to note that few English families still provide a traditional cooked breakfast. Your accommodation includes Continental Breakfast which normally consists of fruit juice, cereal (谷物类食品), bread and tea or coffee. Cheese, fruit and cold meat are not normally part of a Continental Breakfast in England. Dinners usually consist of meat or fish with vegetables followed by desert, fruit and coffee.
Friends
If you wish to invite a friend over to visit, you must first ask your host’s permission. You have no right to entertain friends in a family home as some families feel it is an invasion of their privacy.
Self-Catering Accommodation in Private Homes
Accommodation on a room-only basis includes shared kitchen and bathroom facilities and often a main living room. This kind of accommodation offers an independent lifestyle and is more suitable for the long-stay student. However, it does not provide the same family atmosphere as an ordinary homestay and may not benefit those who need to practice English at home quite as much.The passage is probably written for ______.
| A．hosts willing to receive foreign students |

Surface Exploration. Robots make great explorers on planets，moons，and other landing areas. Aside from earth，just about every surface in the solar system is unsafe for humans to explore. The air on most other planets is insufficient(不足的) for humans to breathe，making it necessary to wear a space suit and oxygen equipment. The temperatures on these surfaces are much too hot or much too cold for any humans to withstand（禁得起）．Plus there would be complications with radiation，weather，and a lack of gravity. Robots have much less limitation in these areas and can survive much longer under these conditions.
Data Collection. Robots are designed for collecting scientific data. Robots are also able to perform many tasks at a time and can process information much quicker and more efficiently. Important scientific projects from detecting minerals，analyzing ground samples，and finding water are all performed much quicker and more accurately (精确地) by robots.
Cost Effective. The use of robots has made the cost of space exploration much less expensive than it would cost for humans to do the work. In order to successfully send humans into space we would need to build a vehicle that can not only carry humans，but also enough food and water to keep them alive for the duration of the trip. Moreover，robots have no problems working for hours on end. Robots never complain，they don't require food or water，and they never need a bathroom break.
Space Travel. Over the past 30 years or so there have been many different types of robots used successfully in the exploration of space. Perhaps the most famous and successful robots are the Spirit and Opportunity who have both been exploring the surface of Mars. They have both been very successful with experiments on soil and rocks and have even found evidence of water in Mars' history.According to the passage，which of the following is NOT true?
| A．The use of robots in space exploration costs more than the use of humans. |
| B．It may be dangerous for humans to explore the solar system except the earth. |
| C．Both the Spirit and Opportunity have found the evidence of water in the Mars. |
| D．Many different types of robots have explored the space successfully. |

French surgeons have performed what they said on Wednesday was the world's first partial face transplant--- giving a new nose, chin and lips to a woman attacked by a dog.
Specialists from two French hospitals carried out the operation on a 38-year-old woman on Sunday in the northern city of Amiens by taking the face from a brain-dead woman, who had hanged herself just hours before the operation. Her family agreed on the operation.
“The patient is in an excellent state and the transplant looks normal,” the hospitals said in a brief statement after waiting three days to announce the pioneering surgery.
The woman had been left without a nose and lips after the dog attacked her last May, and was unable to talk or chew properly. Such injuries are “extremely difficult, if not impossible” to repair using normal surgical techniques, the statement said.
The statement did not say what the woman would look like when she had fully recovered, but medical experts said she was unlikely to resemble the woman who had been the source of her new face.
The operation was led by Jean-Michel Dubernard, a specialist from a hospital in Lyon who has also carried out hand transplants,
Skin transplants have long been used to treat burns and other injuries, but operations around the mouth and nose have been considered very difficult because of the area's high sensitivity to foreign tissue.
Teams in France, the United States and Britain had been developing techniques to make face transplants a reality
There was a short-term risk for the patient if blood vessels became blocked, a medium-term danger of her body rejecting the new skin and a long-term possibility that the drugs used could cause cancers.
Experts say that although such medical advances should be celebrated, the transplant had thrown up moral（道德的）and ethical(伦理的)issues. Little is known about the psychological effect of the transplant. The best title for the passage would be ________.
| A．French Woman has First Partial Face Transplant |
| B．First Face Transplant Opens Debate |
| C．Risks and Ethical Problems of a Face Transplant |
| D．A Complete Face Transplant of a French Woman |
Why did the woman need such an operation?
| A．Her face had been bitten by a dog |
| B．Her face had been burnt in a fire. |
| C．She was born especially ugly |
| D．She wanted to test such an operation. |
The underlined word "resemble" means ________.
| A．to remember forever |
| B．to recognize immediately |
| C．to set as an example |
| D．to presents similarity or likeness to |
What can we learn about the operation?
| A．The woman had used the dead woman' s whole face. |
| B．There has arisen a debate about the operation. |
| C．The woman will suffer from psychological damage soon. |
| D．Such transplants have been performed by doctors. |
Which of the following is NOT one of the risks of the operation?
| A．Block of blood vessels. |
| B．Organ rejection |
| C．Heart damage. |

The United Nations says forty million people or so around the world went hungry in 2008, mainly because of higher food prices. Early estimates（估计） from the UN Food and Agriculture Organization (FAO) show that 963 million people did not get enough to eat.
World food prices have dropped since early 2008. Prices of major crops have decreased by more than half from their height earlier last year. But they remain high compared to earlier years.
But FAO official Hafez Ghanem says lower prices have failed to end the food crisis (危机) in many poor countries. “For millions in developing countries,” he says, “getting enough food every day to live an active and healthy life is a distant dream.”
The FAO says food shortage is a threat to people's health. Today, two-thirds of the world's undernourished people live in just a few countries. These are India, the Democratic Republic of Congo, Bangladesh, Indonesia, Pakistan, Ethiopia and so on.
A report on food insecurity warns that the current economic crisis could send even more people into hunger and poverty.
In sub-Saharan Africa, the percentage of the people who continually go hungry fell from 34% in 1997 to 30% in 2008. But the FAO says Ghana is the only country that has reached two sets of hunger reduction targets. These were set by the 1996 World Food Summit and the Millennium Development Goals. The main reason is the growth in agricultural production in Ghana.
The FAO says some countries in Southeast Asia like Thailand and Vietnam have made progress in hunger reduction goals. But South Asia and Central Asia haven't, and North Korea is still in hot water.What FAO official Hafez Ghanem says implies（暗示）__________
| A．it's easy but takes long to provide people with enough food |
| B．enough food can make people more active and healthier |
| C．there is difficulty solving the food shortage in a short time |
| D．people in developing countries will never get enough food |
Ghana has reached the targets of hunger reduction mainly because of ________.
| A．the still high food prices |
| B．the donation of developed countries |
| C．the two targets of hunger reduction |
| D．the growth in agricultural production |
The underlined word "undernourished" in Para. 4 probably means ________.
| A．hungry and unhappy |
| B．unhealthy for lack of food |
| C．not fat because of poverty |
| D．undeveloped and poor |
Which country has not made progress in hunger reduction?
| A．North Korea | B．Thailand | C．Vietnam | D．Ghana |
What is the best title of this passage?
| A．The food production of the world |
| B．The hunger reduction target of the FAO |
| C．The food shortage around the world |
| D．The solution to the global food shortage |
Most people go to a doctor in their own town or suburb （郊区）. But people in the Australian outback can’t get to a doctor quickly. The nearest doctor is sometimes hundreds of kilometers away so they have to call him on a two-way radio. This special doctor is called the “flying doctor”. He visits sick people by plane.
When someone is very sick, the doctor has to fly to the person’s home. His plane lands on a flat piece of ground near the person’s house. Sometimes the doctor has to take the patient to hospital. Flying doctors take about 8,600 people to hospital each year.
However, most of the time the person isn’t very sick, and the doctor doesn’t have to visit. He can give advice on the radio from the office at the flying doctor center. He can tell the patient to use some medicine from a special medicine chest (箱子). There is one of these chests in every home in the outback. Each bottle, tube （管子） and packet （包） in the chest has a number. The doctor often says something like this,” take two tablets （药片） from bottle 5 every four hours.” Some people in the Australian outback can’t get to a doctor quickly. Because_________
