【题目】 Bats are the only mammals that can fly a great distance, but they have another ability. Many bats live a very long time for an animal of their size. European researchers are studying bats to understand why they live so long. They hope to make discoveries aimed at fighting the aging process in human beings.

Last week, the group of scientists said they had identified important biological qualities in some bat species. The group studied the bats’ chromosomes (染色体), a line of genes found in the nucleus of cells. The scientists were most interested in structures connected to the ends of the chromosomes. They are called telomeres (端粒), which protect the ends of chromosomes and shorten each time a cell divides. Scientists believe this shortening process causes cells to break down. They say this is what cause aging.

The European researchers studied 493 bats from four bat species. The group used information that had been gathered over more than 60 years. Of these animals, the greater mouse-eared bat generally lived the longest, an average of 37 years. The scientists said this and a related species, which are grouped together under the name Myotis, had telomeres that did not shorten with age. Another Myotis bat holds the record for the oldest age, reaching 41 years. The scientists’ findings suggest that these bats’ cells have the ability to maintain and repair their telomeres. This helps guard against the aging process.

Based on its body size, a bat like the greater mouse-eared bat would be expected to live four years. But, these mammals have been found to live nearly 10 times longer than that. The scientists found that only 19 species of mammals live longer than humans when their body size is considered. Eighteen of these are bats.

【1】Why are European researchers studying bats?

A.To learn the similar habits between bats and human beings.

B.To find out why the greater mouse-eared bats live a long life.

C.To try to understand why bats prefer to fly during the night.

D.To discover a good way to prevent human beings from aging.

【2】What does the second paragraph mainly explain to us?

A.The structures of the bats’ chromosomes.B.What causes aging biologically.

C.The functions of telomeres.D.What causes cells to break down.

【3】Why do the greater mouse-eared bat and another Myotis bat live so long?

A.They are grouped together under the name Myotis.

B.Their telomeres are decreasing with age.

C.Their cells are able to keep up and fix their telomeres.

D.They have more telomeres than human beings do.

【4】What can we infer from the last paragraph?

A.Bats live 10 times longer than other mammals.

B.Bats enjoy the longest life among mammals.

C.The greater mouse-eared bat and other bats should have lived longer.

D.Many bats live longer than human beings considering their body size.

【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.

【1】What does the author intend to tell us?

A.AI technology will aid to predict some cancers.

B.Doctors will be replaced by AI machines.

C.AI technology will help cancer treatment.

D.Doctors will get improved with AI technology.

【2】What is vital for an AI machine to do its medical job according to USC researchers?

A.Cell counting machines.B.Well designed process.

C.Patterns of cancer.D.Enough information of patients.

【3】What is Paragraph 3 mainly about?

A.When is the best time to remove cancer.B.Why USC researchers argue about AI.

C.What treatment AI technology provides.D.How AI technology helps in medicine.

【4】What section of a magazine is the text probably taken from?
