　　Stress caused by social situations, such as giving a speech or going to a job interview, can affect some people’s immune system in ways that harm their health, researchers have found.

　　The study included 124 volunteers who were purposely put into embarrassed social situations. Those who showed greater neural (神经) sensitivity to social rejection also had greater increases in inflammatory (炎症) activity when exposed to social stress.

　　“It turns out there are important differences in how people explain and respond to social situations,” lead author George Slavich, at the Cousins Center for Psychoneuroimmunology at the University of California, Los Angeles, said in a UCLA news release.

　　“For example,” he explained, “we sometimes see giving a speech in front of an audience as a welcomed challenge; other times, it’s threatening and sad. In this study, we sought to examine the neural bases for these differences in response and to understand how these differences relate to biological processes that can affect human health and well-being.”

　　The findings provide “further evidence of how closely our mind and body are connected. We have known for a long time that social stress can get under the skin to increase risk for disease, but it’s been unclear exactly how these effects occur. As we know, this study is the first to identify the neurocognitive (神经认知) pathways that might be involved in inflammatory responses to sharp social stress,” Slavich said.

　　Increases in inflammatory activity are part of the immune system’s natural response to potentially harmful situations, but “frequent or chronic (慢性的) activation of the system may increase the risk for a variety of illnesses,” Slavich added.

　　The study was released online Aug. 2 in advance of publication in an upcoming print issue of the Proceedings of the National Academy of Sciences.

　　A. those who were more sensitive to social rejection

　　B. those who were purposely put into society

　　3. The author quotes examples of the fourth paragraph mainly to　.

　　A. show further evidence of how closely our mind and body are connected

　　B. prove important differences in how people explain and respond to social situations

　　C. explain volunteers are sensitive to social rejection when exposed to social stress

　　D. make clear that how stress caused by social situations breaks down immune system

　　4. We can infer that　if there is inflammatory response in people’s immune system.

　　较难题目特训：介绍说明类

　　阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。

　　A Train Floating On Air

　　A train that floats on air? It’s not magic — it’s magnets (磁). And it’s close to reality.

　　In Virginia USA the fall of 2002, a train with no wheels traveled on air and carried college students across their campus. In Japan, a whisper-quiet railway engine hovered and raced at 350 miles per hour using magnets and electricity as the power. And in China, a magnet train line linked Shanghai with nearby Pudong Airport.

　　These trains use magnetic levitation (悬浮) technology, “maglev” for short. They use the same rules as the magnets you pick up at home or school: opposite poles of magnets attract each other, and like poles repel each other.

　　How does it work?

　　Powerful magnets on the bottom of the train repel magnets on the track, which is actually just a magnet-filled guiding way. With a magnetic field of sufficient force, the train will go hovering on air, which seemed impossible to us in the past.

　　When an electrical current is sent through the track, the train moves. Turn the current backwards and the train slows down.

　　Maglev doesn’t rely on the friction (摩擦力) of wheels on track, so it can climb a much steeper hill than a traditional train. And it can travel easily in snow and ice, something that could bring normal trains to a screaming stop.

　　1. This passage is about　.

　　A. maglevB. magnetsC. levitationD. electricity

　　2. Which of the following is a repelling action?

　　A. ⇨⇦ B. ⇦⇨ C. ⇧⇧ D. ⇩⇩

　　3. What can we learn from the text?

　　A. A magnet-filled guiding way is formed inside a maglev train.

　　B. Instead of electricity, magnets are used as the power of a maglev.

　　C. Maglev trains can climb hills with the help of magnet wheels.

　　D. Electric currents decide the movements of a maglev train.

　　4. What is the difference between a maglev train and an ordinary train?

　　A. A maglev train can climb mountains without power while an ordinary one can’t.

　　B. A maglev train can travel in college campus while an ordinary train is not allowed.

　　C. Traveling without a track, a maglev train is safer and smoother than an ordinary one.

　　D. Floating on a track, a maglev train is faster, quieter than an ordinary railway train.
