Then we can focus on our jobs instead of just worrying.This is probably why NASA wants an astronaut with a sense of humor.

Or, picture a car windshield that stores the sun39。 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。 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.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 and then releases it as heat to make the ice on the windshield disappear. 7．閱讀理解 可知選C。 （3）考查細(xì)節(jié)理解。 出于好奇心，他們做了一系列實(shí)驗(yàn)。 needs and drive cooperative behavior as a result. Curious to find out, they did a series of experiments.” （2）考查細(xì)節(jié)理解。然而，他們還推斷，這種方式可能會導(dǎo)致人們更加了解他人的需求，從而推動合作性的行為。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. However, they also reasoned that it could instead lead people to bee more aware of others39。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(jié)果。D.To reward them for their participation.C.To add to their energy.To confirm sharing food can promote cooperation.D.To show the way food is served.B.D.A meal shared with others.C.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. 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. needs and drive cooperative behavior as a result. Curious to find out, they did a series of experiments. Kaitlin Woolley and Ayelet Fishbach report in Psychological Science that a meal taken familystyle from a central plate can greatly improve the oute of later negotiations. 【點(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測，推理判斷和段落大意四個題型的考查，是一篇科研類閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。 （4）考查詞義猜測。在大型公共場所，很難像機(jī)場那樣設(shè)置昂貴的安檢設(shè)施。s hard to set up expensive screening equipment like what39。根據(jù)第四段中的“noting its design can inspect bags or luggage without being an exposure to privacy.”可知，不用打開和檢查人們的個人物品，避免了侵犯隱私，可知選D。可知選B。 （1）考查段落大意。D.Discovering.B.Confirming.D. privacy.To make full use of WiFi.C.It protects personal information from being disturbed.（3）Why did the researchers study the device according to Yingying Chen? A.It uses antennas to pick up networks39。It saves people in danger of natural disasters.B.The benefit of the study findings.（2）What39。The principle the study is based on.B. The peerreviewed study, which recently won a best paper award at the 2018 IEEE Conference on Communications and Network Security, is now published online. Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes, researchers said.（1）What does paragraph 3 talk about?
