【题目】 Artificial intelligence (AD) technology may soon be a useful tool for doctors. It may help them better understand and treat diseases like breast cancer in ways that were never before possible.
Rishi Rawat, who teaches AI at the University of Southern California's (USC) Clinical Science Center in Los Angeles, is part of a team of scientists who are researching how AI and machine learning can more easily recognize cancerous growths in the breast.
Rawat provides information about cancer cells to a computer. He says this data helps the machine learn. “... You can put the data into them and they will learn the patterns and the pattern recognition that's important to making decisions"" David Agus, another USC researcher, believes that machines are not going to take the place of doctors, but they will help make certain decisions and look for things that the human brain can't recognize.
Once a confirmed cancerous growth is removed, doctors still have to treat the patient to reduce the risk of cancer returning. The form of treatment depends on the kind of cancer. Currently, researchers take a thin piece of tissue, put it on a small piece of glass and add color to better see the cells. The process could take days or even longer. Scientists say artificial intelligence can do something better than just count cells. Through machine learning, it can recognize complex patterns or structures, and learn how the cells are organized. They hope that machines will soon be able to make a quick identification of cancer that is free of human mistakes.
"All of a sudden, we have the computing power to really do it in real time...We couldn't have done this, but now it's all changed."" Agus adds that the process could be done for almost no cost in the developing world." He says that having a large amount of information about patients is important for a machine to effectively do its job in medicine.
The USC researchers are now only studying breast cancer. But doctors predict artificial intelligence will one day make a difference in all forms of cancer.

【题目】 The $380,000 aircraft, called the "Speeder", will be able to reach at least 150 miles per hour and have a 45-mile range and fly as high as 15,000 feet when it is on sale next year, according to David Mayman, CEO of JetPack Aviation, one of the companies that create and sell flying vehicles. This motorcycle can take off vertically (垂直地) from the grassland or a street and land on the other side of the city in a similar position. This idea has always been treated like science fiction.
At some point, the Speeder could be adapted to use electric energy, which is more environmentally friendly, but for now, Mayman said, no battery cells come close to the speed and potential power created by jet engines. Besides, like other developing similar craft, currently the Speeder will only be used for recreation and sport until laws and regulations begin to change in America.
Mayman argued that there was a large role for the Speeder to play in both civilian and military life. He said his company has been working for several years to develop a jet pack that could be used by Special Forces soldiers. As their cost continued to increase, he said, engineers began designing a personal aircraft that eventually turned into the Speeder.
Mayman said that the aircraft could be used to transport heavy loads or move soldiers on and off the battlefield, especially in areas too dangerous for helicopters. Unlike other flying vehicles, the craft is small enough to sit on the back of a boat or can be easily delivered by a common fighting vehicle.
【1】What can we infer about the Speeder according to paragraph 1? ______
A.It can fly 150 miles without stop.
B.It is created by several companies.
C.It has already appeared in markets.
D.It can land on a school playground.
【2】What limits the use of the Speeder at present? ______
A.The financial crisis.
B.The government policy.
C.The bad environment.
D.The technology development.
【3】What was the Speeder first intended for? ______
A.Sports games.
B.Military force.
C.Electrical engineering.
D.Public transportation.
【4】What advantage does the Speeder have when compared to other flying vehicles? ______
A.Its high speed to move heavy loads.
B.Its potential to use electric energy.
C.Its ability to replace helicopters.
D.Its small size that makes it convenient.

The other day I happen to read an eighty-word passage about details. I found it prettily good.
One who wants to achieve great success should pay attentions to details. Sometimes it is the details in that determine our success, for it has a great impact on what we’re doing. We should form the habit of being careful, so a careful person rarely overlooks details. What’s more, we should learn to keep balance of quantity and quality. When facing with lots of work, the faster we do them, the more mistakes we usually make. In that case we are possible to neglect the details. So we should remember that quality comes first, without that quantity is of no importance.

【题目】 Education is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them. Our purpose is to fit them for life.
In some modern countries it has for some time been fashionable to think that by free education for all whether rich or poor, clever or stupid, one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough: we find in such countries a far larger number of people with university degrees; they refuse to do what they think “low” work; and in fact, work with hands is thought to be dirty and shameful. But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor; we can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we would get terrible diseases in our towns.
In fact, when we say that all of us must be educated to fit us for life, it means that we are educated in such a way that, firstly, each of us can do whatever work suited to his brains and ability, and secondly, that we realize that all jobs are necessary to society, and that it is very bad to be ashamed of one’s work. Only such a type of education can be considered valuable to society.
【1】The writer of this passage thinks that________.
A.free education can solve all of the world’s problems
B.free education for all probably leads to a perfect world
C.free education won’t help to solve social problems
D.all the social problems can’t be solved by free education
【2】According to the passage, ________.
A.work with hands is dirty and shameful
B.work with hands is low work
C.work with hands is the most important
D.we can’t regard work with hands as low work
【3】The purpose of education is _________.
A.to choose a system of education
B.to let everyone receive education
C.to prepare children for their future life
D.to prepare children for well-paid jobs
