Want a glance of the future of health care? Take a look at the way the various networks of people about patient care are being connected to one another, and how this new connectivity (连通性)is being used to deliver medicine to the patient—no matter where he or she may be.
Online doctors offering advice based on normal symptoms (症状)are the most obvious example. Increasingly, however, remote diagnosis (远程诊断)will be based on real physiological data (生理数据)from the actual patient. A group from the University of Kentucky has shown that by using personal data assistance plus a mobile phone, it is perfectly practical to send a patient's important signs over the telephone. With this kind of equipment, the cry asking whether there was a doctor in the house could well be a thing of the past.
Other medical technology groups are working on applying telemedicine to countryside care. And at least one team wants to use telemedicine as a tool for disaster need—especially after earthquakes. On the whole, the trend is towards providing global access to medical data and experts' opinions.
But there is one problem. Bandwidth (宽带)is the limiting factor for sending complex medical pictures around the world —CT photos being one of the biggest bandwidth users. Communication satellites may be able to deal with the short-term needs during disasters such as earthquakes or wars. But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of remote medical service.
Doctors have met to discuss computer-based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should start a new time when telemedicine and the sharing of medical information, experts, opinions and diagnosis are common. The writer mainly talks about _____ .
| A．the use of telemedicine |
| B．the online doctors |
| C．medical care and treatment |
| D．communication improvement |
The basis of remote diagnosis will be _____ .
| A．personal data assistance |
| B．some words of a patient |
| C．real physiological information |
| D．medical pictures from the Internet |
Which of the following statements is true according to the text?
| A．Patients don't need doctors in hospitals any more. |
| B．It is impossible to send a patient's signs over the telephone. |
| C．Many teams use telemedicine dealing with disasters now. |
| D．Broadband communications will become cheaper in the future. |
The "problem" in the fourth paragraph refers to the fact that _____ .
| A．bandwidth isn't big enough to send complex medical pictures |
| B．the second-generation of Internet has not become popular yet |
| C．communication satellites can only deal with short-term needs |
| D．there is not enough equipment for spreading the medical care |
The heart of Mexico is a high, oval valley surrounded by mountains. Once, forests covered the mountainsides, and broad, shining lakes covered nearly all the valley floor. Now, the mountains are bare and scarred with erosion（侵蚀）, and much of the valley floor is dry and dusty.
Cortez and his Spanish soldiers were the first Europeans to enter this valley. They saw the thriving Aztec city of Tenochtitlan rising from an island in one of the lakes. Surrounding it were green floating gardens. The Spaniards said it was as beautiful as a dream. Then the conquest began.
By 1521, when the Spaniards had conquered the fierce Aztecs, the island city was in ruins. Cortez decided to rebuild it after the pattern of European cities. Using the conquered Aztecs as slave laborers, Cortez built the new city, now Mexico City, in just four years.
“But a generation had scarcely passed after the conquest before a sad change came over these scenes so beautiful,” writes one historian. The broad, shining lakes began to dry up.
Modern historians believe that Cortez began the destruction of the valley’s lakes when be ordered the city rebuilt. A great deal of charcoal was needed to burn the limestone (石灰石) from which cement (水泥) and mortar were made. Wood was needed to finish the interiors of the buildings.
The mountainside forests were destroyed to provide the charcoal and wood. Once the sloped were bare, rainfall o longer seeped (渗漏) slowly into the earth to feed the springs that filled the valley’s lakes. Instead, rainfall poured off the mountainsides the city from floods, later rulers made a cut through the mountains so that the water drained away into another valley. Mexico City, once an island, had become a city of a dry plain. The underlined word “thriving” in the second paragraph means _______.

Tristan da Cunha, a 38 –square –mile island, is the farthest inhabited island in the world, according to the Guinness Book of Records. It is 1,510 miles southwest of its nearest, St. Helena, and I, 950 miles west of Africa. Discovered by the Portuguese admiral (上将) of the same name in 1506, and settled in 1810, the island belongs to Great Britain and has a population of a few hundred.
Coming in a close second –and often wrongly mentioned as the most distant land –is Easter Island, which lies 1,260 miles east of its nearest neighbor, Pitcairn Island, and 2,300 miles west of South America.
The mountainous 64 –square –mile island was settled around the 5th century，supposedly by people who were lost at sea. They had no connection with the outside world for more than a thousand years, giving them plenty of time to build more than 1,000 huge stone figures, called moai, for which the island is most famous.
On Easter Sunday, 1722, however, settlers from Holland moved in and gave the island its name. Today, 2,000 people live on the Chilean territory (智利领土). They share one street, a small airport, and a few hours of television per day. It can be learned from the text that the island of Tristan da Cunha ________.

If we are asked exactly what we were doing a year ago, we might have to say that we could not remember. But if we had kept a book and written in it an account (陈述) of what we did each day, we should be able to give an answer to the question.
It is the same in history. Many things have been forgotten because we do not have any written account of them. Sometimes men did keep a record of the important happenings in their country, but often it was destroyed by fire or in a war. Sometimes there was never any written record at all because the people of that time and place did not know how to write. For example, we know a great deal about the people who lived in china 4,000 years ago, because they could write and leave written records for whose who lived after them. But we know almost nothing about the people who lived even 200 years ago in central Africa, because they had not learned go write.
Sometimes, of course, even if the people cannot write, they may know something of the past. They have heard about it from older people, and often songs and dances and stories have been made about the most important happenings, and those have been sung and acted and told for many generations, for most people are proud to tell what their fathers did in the past. This we may call ‘remembered history’. Some of it has now been written history, because words are much more easily changed when used again and again in speech than when copied in writing. But where there are no written records, such spoken stories are often very helpful. Which of the following ideas is NOT talked about in the passage above?
| A．“Remembered history” is less reliable than written history. |

“Remembered history”is regarded as valuable only when .
| A．it is written down | B．there is no written account |

John H. Johnson was born in a black family in Arkansas City in 1981. His father died in an accident when John was six. He was reaching the high school age, but his hometown offered no high school for blacks.
Fortunately he had a strong—willed caring mother. John remembered that his mother told him many times, “Son, you can be anything you want really to be if you just believe.” She told him not to depend on others, including his mother. “You have to learn success” she said. “All the people who work hard don’t succeed, but the only people who do succeed are those who work hard.”
These words, came from a woman with less than a third grade education. She also knew that believing and hard work don’t mean everything. So she worked hard as a cook for two years to save enough to take her son, who was then 15, to Chicago.
Chicago in 1933 was not the promised land that black southerners were looking for. John’s mother and stepfather could not find work. But here John could go to school, and here he learned the power of words--as an editor of the newspaper and yearbook at Du Sable High School. His wish was to publish a magazine for blacks.
While others discouraged him, John’s mother offered him more words to live by “Nothing beats a failure but a try.” She also let him pawn（典当） her furniture to get the $ 500 he needed to start the Negro magazine.
It is natural that difficulties and failures followed john closely until he become very successful. He always keeps his mother’s words in mind:” Son, failure is not in your vocabulary!” Now John H. Johnson is one of the 400 richest people in America--worth $150 million. What does the story mainly want to show us?

| B．The mental support John’s mother gave him. |
| C．The importance of a good education. |
| D．How John H. Johnson became successful. |
Why did John’s mother decide to move to Chicago?
| A．Because his father died when John was very young. |
| B．Because life was too hard for them to stay on in their hometown. |
| C．Because John needed more education badly. |
| D．Because there were no schools for Negroes in their hometown. |
Which of the following statements is TRUE according to the passage?
| A．John’s mother didn’t believe in or depend on others. |
| B．John’s mother believed one would succeed without working hard. |
