【文章內容簡介】 one of whom knew each other. The participants were seated at a table and fed tortilla chips with salsa. Half the pairs were given their own basket of 20 grams of chips and a bowl of 25 grams of salsa, and half were given 40 grams of chips and 50 grams of salsa to share. As a cover for the experiment, all participants were told this snack was to be consumed before the game began. The game asked the participants to negotiate an hourly wage rate during a fictional strike. Each person was randomly assigned to represent the union or management and follow a set of rules. The researchers measured cooperation by noting the number of rounds it took to reach an agreement, and found that those who shared food resolved the strike significantly faster（in 8. 7rounds）than those who did not（ rounds）. A similar experiment was conducted with 104participants and Goldfish crackers（餅干）, this time negotiating an airline39。s route prices. The results were much the same, with the foodsharers negotiating successfully 63. 3%of the time and those who did not share doing so 42. 9%of the time. （1）What does the familystyle meal in the report refer to？ A.A meal taken at home.B.A meal shared with others.C.A meal consumed by oneself.D.A meal taken in a family atmosphere.（2）For what purpose did the researchers carry out the present experiments? A.To show the way food is served.B.To prove sharing food increases petition.C.To confirm sharing food can promote cooperation.D.To find out whether sharing food can get people close emotionally.（3）Why were participants asked to eat up the snack before the game? A.To add to their energy.B.To reward them for their participation.C.To hide the intention of the experiment.D.To avoid the distraction during the game.【答案】 （1）B（2）C（3）C 【解析】【分析】本文是一篇說明文，介紹了外交宴席的心理學，研究表明，從中間菜采取的“家庭式”餐，可以大大改善后續(xù)談判的結果。 （1）考查細節(jié)理解。根據(jù)第二段中的“They theorized that, on the one hand, sharing food with other people might indicate food scarcity（短缺）and increase a feeling of petition.

Or, picture a car windshield that stores the sun39。s energy and then releases it as heat to make the ice on the windshield disappear. According to a team of researchers at MIT, both cases may be possible before long, thanks to a new material that can store solar energy during the day and release it later as heat. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing. Solar energy is only available about half the time we need it — during daylight. For the sun to bee a major power provider for human needs, there has to be an efficient way to save it up for use during nighttime and stormy days. Most such efforts have focused on storing and recovering solar energy in the form of electricity, but the new finding, by MlI professor Jeffrey Grossman, Postdoc David Zhitomirsky and graduate student Eugene Cho, could provide a highly efficient method for storing the sun39。s energy through a chemical reaction and releasing it later as heat. The key to enabling longterm, stable storage of solar heat, the team said, is to store it in the form of a chemical change rather than storing the heat itself. But heat will disappear over time no matter how good the material around it is, so the team set up a chemical storage system that can keep the energy in a stable molecular configuration. When exposed to sunlight, the molecules can stay that way for long periods Then, when triggered (觸發(fā))by a very specific temperature or something else, the molecules return to their original shape , giving off heat in the process. Such chemicallybased storage materials, known as Solar Thermal Fuels(STF), have been developed before. But those earlier efforts were designed to be used in liquid solutions and not able to make durable (耐用的) solidstate films. The new approach is the first based on a solidstate material, in this case a polymer, and the first based on inexpensive materials and widespread production technology.（1）What is the main purpose of Paragraph 1? show the main idea of the passage. practice readers39。 imagination. interest readers in the passage. introduce a new kind of material.（2）According to the passage, what can the polymer film do? can be made into window glass. can make necessary electricity. can store energy and release sunshine. can absorb sunshine and give off heat.（3）According to the passage, what is STF based on? chemical reaction. movement of heat. form of electricity. physical reaction.（4）What is the advantage of the molecular configuration? is less expensive. is very powerful. is easily available. is less changeable.【答案】 （1）C（2）D（3）A（4）D 【解析】【分析】本文是一篇說明文，介紹了一種新型材料，它可以通過自身吸熱并儲存熱量，之后能夠根據(jù)需要釋放熱。 （1）考查推理判斷。根據(jù)第一段“Imagine your clothing could release enough heat to keep you warm and cozy, allowing you to stay fortable in a cooler room.
