Ⅰ. 阅读理解

A

With the undeniable increase in greenhouse emissions on Earth, there can be no doubt that the earth is becoming warmer, and scientific studies have proven that if we carry on living the way we do, then global temperatures will rise even more.

So what exactly does this mean for the future of our planet? Global warming will in fact cause extreme weather conditions, meaning that our winters would be even colder than they are now. More than that, warmer temperatures will lead to the melting of ice in the north and south poles, which in turn will lead to rising sea levels across the globe. This is particularly troubling for low coastal regions and some island countries. In 1 000 years or so, all these places will be flooded underwater.

So where will we be able to live? Unless we can find a way to evolve into mermaids and mermen, which doesn’t look promising, the only solution is to move elsewhere. There will be little choice left once a large proportion of the land is lost to the sea, and other remaining places will be so hot that it will be absolutely impossible for us to survive. Countries that we consider to be hot these days will be even more so if temperatures increase by 5, 10, even 15 degrees. It is possible, then, that the once frozen poles of the Arctic and Antarctica will be suitable enough to live in, having melted its ice and warmed up.

It’s scary to think of our descendents(后代) struggling to survive in a virtually uninhabitable world. Perhaps if people start to realize how their actions now can have such an impact on future generations, they will change their attitude and start to think more about caring for the environment. If not, we’ll be living in a world underwater and will need to think of a way to turn ourselves into mermaids! 【文章大意】如果不改变我们现在的生活方式, 地球温度将继续上升, 导致海水上涨, 低海拔地区将被淹没, 其他地区也将热得无法生存, 人们不得不进化成“美人鱼”!

1. What about our planet in 1 000 years according to the text? A. There will be more water. B. Winter will become mild. C. Low-lying islands will disappear. D. Sea levels will rise in the polar regions.

【解析】选C。细节理解题。根据第二段最后一句可知, 如果气温继续上升, 大约1 000年后, 低海拔的沿海地区将被水淹没。故选C。 2. What can be inferred from Paragraph 3? A. Hot places today will become colder. B. Humans might evolve into mermaids. C. Fewer places will be suitable to live. D. The earth will be totally covered by water.

【解析】选C。推理判断题。根据第三段内容可知, 气候持续变暖会导致海平面上升, 淹没大部分地区, 适合人们居住的空间越来越小。C选项符合题意。 3. What does the author appeal to people to do?

Artificial intelligence (AI) 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 teaches AI at the University of Southern California’s (USC) Clinical Science Center in Los Angeles. He 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 for a computer. He says this data helps the machine learn. “You can put the data into computers and they will learn the patterns and the pattern recognition is important to making decisions. ”

David Agus is another USC researcher. He says machines are not going to take the place of doctors. “Computers will not treat patients, but they will help make certain decisions and look for things that the human brain can’t recognize by itself. 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. That 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.

The hope is 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, we didn’t have the
