Aside from the earth, just about every surface in the solar system is unsafe for humans to explore. The air on most other planets is insufficient for humans to breathe, making it necessary to wear a space suit and oxygen equipment. The temperatures on these surfaces are much too hot or much too cold for any humans to withstand. Plus there would be plications with radiation, weather, and a lack of gravity. Robots have much less limitation in these areas and can survive much longer under these conditions. 　　Robots are designed for collecting scientific data. Robots are also able to perform many tasks at one time and can process information much quicker and more efficiently. Important scientific projects from detecting minerals, analyzing ground samples, and finding water are all performed much quicker and accurately by robots. 　　The use of robots has made the cost of space exploration much less expensive than it would cost for humans to do the work. In order to successfully send humans into space we would need to build a vehicle that can not only carry humans, but also enough food and water to keep them alive for the duration of the trip. Moreover, robots have no problems working for hours on end. Robots never plain, they don’t require food or water, and they never need a bathroom break. 　　Over the past 30 years or so there have been many different types of robots used successfully in the exploration of space. Perhaps the most famous and successful robots are Spirit and Opportunity who have both been exploring the surface of Mars. They have both been very successful with experiments on soil and rocks and have even found evidence of water in Mars’ history. 【文章大意】本文是一篇說明文, 介紹了機(jī)器人對太空探索非常重要, 機(jī)器人正用于太空探索。主旨大意題。25. According to the passage, which of the following is NOT true?A. The use of robots in space exploration costs more than the use of humans. B. It is dangerous for humans to explore other surfaces in the solar system except the earth. C. Both Spirit and Opportunity have found the evidence of water on Mars. D. Many different types of robots have explored the space successfully. 【解析】選A。根據(jù)倒數(shù)第二段中的“The use of robots has made the cost of space exploration much less expensive than it would cost for humans to do the work. ”可知, 用機(jī)器人進(jìn)行太空探索比人類從事這項工作花費(fèi)更少。A. remain　　 B. bear　 　C. defeat　 　D. develop【解析】選B。根據(jù)畫線詞前的“The temperatures on these surfaces are much too hot or much too cold for any humans to”可知, 溫度太高或太低, 人類無法忍受, 由此可知畫線詞詞義為“忍受”。觀點(diǎn)態(tài)度題?！痉椒记伞靠破照f明文的詞義猜測題難度較大, 對畫線詞所在句的理解是關(guān)鍵, 要緊緊抓住畫線詞前后的詞語, 例如第26題, 根據(jù)畫線詞前的“much too hot or much too cold”可知, 當(dāng)溫度太高或太低時, 人類無法忍受, 由此可知畫線詞詞義為“忍受”。文章講述的是“手指在你的手機(jī)上留下關(guān)于你的線索。28. By studying the residues on the phone, we can conclude its user’s _______. 推理判斷題。每種化學(xué)物質(zhì)都為你和你的行為提供線索。)可知, 通過研究手機(jī)上的殘留物, 我們可以得出手機(jī)用戶的生活方式。推理判斷題。然后他們將這些數(shù)據(jù)與化學(xué)數(shù)據(jù)庫進(jìn)行比較。多瑞斯坦(Pieter Dorrestein)幾年前幫助建立了這個數(shù)據(jù)庫, 其中包含各種物質(zhì), 包括香料、咖啡因和藥物。30. What’s the author’s attitude towards the application of the research finding?A. Doubtful. B. Disappointed. C. Positive. D. Uninterested. 【解析】選C。根據(jù)最后一段Police already use molecular analyses to look for traces of explosives or illegal drugs. To date, Dorrestein says, he’s never heard of police using phone residues to narrow down behaviour clues to search for a suspect. But detectives might one day use such data to track down someone who left a phone behind at a crime scene. (警方已經(jīng)使用分子分析來尋找爆炸物或非法毒品的蹤跡。但是有一天偵探們可能會利用這些數(shù)據(jù)來追蹤某個把手機(jī)落在犯罪現(xiàn)場的人。31. What should be the best title for the text?A. Cell Phones Will Be Used in More Fields. B. Molecules Are Used to Search for Illegal Drugs. C. Your Phone May Be Home to Various Chemicals. D. Fingers Leave Clues About You on Your Phone. 【解析】選D。根據(jù)第一段Every time your fingers touch your cell phone, they leave behind trace of amounts of chemicals. And each chemical offers clues to you and your activities. By studying them, scientists might be able to piece together a story about your recent life, a new study finds. (每次你的手指觸碰手機(jī)時, 都會留下微量的化學(xué)物質(zhì)。一項新的研究發(fā)現(xiàn), 通過研究它們, 科學(xué)家們也許能夠拼湊出一個關(guān)于你最近生活的故事。DPhiladelphia’s Magic Gardens makes up a folk art center, gallery space, and a nonprofit organization showcasing the works of mosaicist(鑲嵌設(shè)計師)Isaiah Zagar. Zagar devoted himself to beautifying the South Street neighborhood in the late 1960s, when he moved to the area with his wife Julia. The couple helped the area by purchasing and repairing some old buildings, often adding colorful mosaics on both their private and public walls. The first such project was Julia’s stillbusy folk art store, the Eyes Gallery at 402 South Street. Zagar started working on the Magic Gardens in 1994 in the deserted parking lot near his studio. He spent the next fourteen years sculpting multilayered walls and decorating the 3, 000 square foot space. The installation(裝置藝術(shù)), primarily consisting of found objects and contributions from the munity, finally covers half a city block with countless patterns and
