When you eat out in a restaurant, it is not unusual to hear people yelling, “Let me get this one!” Sometimes you can see them1 or arm wrestling to fight for the2 for paying the bill. These fights are often very loud and active. Each person3 shows an honest desire to pick up the bill, and in the end, all the people at the table give the winner praise and 4 .
In fact, figuring out who will get the bill is always a5 for Chinese people at formal meals. Although the people who6 the meal are very likely to pay the check, it is a7 practice to make an effort to pay the bill. But you will8 them if you do end up actually collecting money.
In recent years, going Dutch has been embraced by many young people. 9 , older generations who fear “losing10 ” still find it embarrassing and mean to calculate each person's 11 of the bill.
But these days, 12 digital payment apps, splitting (分摊) the bill13 is becoming widely-accepted idea. Even people from14 generations may want to do so. By scanning a code 15 paying their share via WeChat or Alipay on their phones in one easy click, Chinese are 16 it easy to relieve the embarrassment of figuring out each person's payment when they order a meal. This function has made going Dutch less17 and more fun in China. “Many of us are never without our phones 18 they are convenient. And person-to-person mobile payment services are incredibly19 to use and at the same time save the trouble of20 change,” said 18-year-old Han Chen, a student from Senior High School.

【题目】Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.

“To provide enough power, we need certain methods with high energy density (密度)”,said Jae Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope (放射性同位素) battery can provide power density that is much higher than chemical batteries.”

Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro/nanoelectromechanical systems (MNEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.

“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”

His new idea is not only in the battery’s size, but also in its semiconductor(半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.

“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”

Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery, In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.

1Which of the following is TRUE of Jae Kwon?

A. He developed a chemical battery.

B. He teaches chemistry at MU.

C. He made a breakthrough in computer engineering.

D. He is working on a nuclear energy source.

2Liquid semiconductor is used to ________.

A. reduce the damage to lattice structure

B. test the power of nuclear batteries

C. decrease the size of nuclear batteries

D. get rid of the radioactive waste

3According to Jae Kwon, his nuclear battery ________.

A. uses a solid semiconductor

B. will soon replace the present ones

C. could be extremely thin

D. has passed the final test

4The text is most probably a ________.

A. book review

B. science news report

C. newspaper ad

D. science fiction story
