【题目】Will Eating Less Help You Live Longer?

If you want to slow aging, you might want to eat less. Researchers in the United States say eating less can slow the aging process (过程) of cells in the body.

John Price, a professor at Brigham Young University in the U.S. state of Utah, with other researchers, studied two groups of mice. One group was able to eat as ______ as it wanted. The researchers controlled what the second group ate. Their food had 35 percent fewer calories (卡路里) than the first group of mice. Price said the second group of mice was more ______ and had fewer diseases. He and his team found that ______ calories slowed aging.

The researchers found that fewer calories slow down cells’ ribosomes (核糖体). Price explained that ribosomes are used to make important proteins (蛋白质). But with fewer calories, ribosomes slow down. This gives ribosomes more time to ______ themselves. Price used cars to explain this as an example. “Like a car, a ribosome isn’t a simple ______. It needs repairs to change the broken parts. When the glass of the car is broken,” he explained, “you don’t need to throw the ______ car away and buy a new one. It costs less to change the glass.” Price said that because of this, it is ______ to break a whole ribosome when it starts to break down. “Instead, repairing single part of the ribosome makes ribosomes continue producing high quality proteins. This top quality production keeps cells and the whole ______ working well,” he added.

Earlier studies have shown a connection between calorie reduction and slowed aging. However, this is first to show how the ribosomes can ______ aging. Price said the findings help to explain______ exactly people become older. And this may help us make more wise decisions about what we eat.

According to a recent survey, nearly 30% of teenagers in China have been bullied online. The most common form of cyber bullying is the use of bad language.

【题目】 Would you like to live in a city where buildings turn the lights off for you, and self-driving cars will find the nearest parking space themselves? Although it might sound a little far from you, living in a “smart” city like this could happen sooner than you think.

Great changes have taken place in towns that we have lived in for centuries, while completely new cities are being built. One such place is the city of Songdo. Every home there will have a “telepresence” system (远程遥控系统)allowing users to control the heating and looks, take part in video meetings, and receive education, healthcare and government services. Around the city, escalators (自动扶梯) will only move when someone is on them, and offices and schools will all be connected to the system.

The great mind behind Songdo is from the company Cisco. In fact, technology companies around the world such as IBM, Siemens and Microsoft are already in the business.

About 75% of the world’s population will live in cities by 2050, so cities will need to be more modern to deal with the coming problems. “Making cities smarter is one way out, and I think this will in turn make cities greener,” said Dan Hill, the head of a research company.
