A.They sleep upside down.C.Ways in which bats move differently from birds.（2）Which of the following is a false assumption about bats that was recently corrected? A.Why scientists have difficulty observing bats.C. these will vary depending on the area where a bat species makes its home. For example, a cave bat, which regularly lives on a hard stone ceiling, is more careful about its landing preparation than a bat more accustomed to landing in leafy treetops.（1）Which of the following is the topic of the passage? A. In the past it was believed that, in terms of flying mechanics, there was little difference between bats and birds. This belief was based only on assumption, however, because for years nobody had actually studied in detail how bats move their wings. In recent years, though, researchers have discovered a number of interesting facts about bat flight. Bats are built differently from birds, and their wings are made up of both their front and hind limbs (肢體). This makes coordinating (協(xié)調(diào)) their limbs more difficult for bats and, as a result, they are not very good at flying over longer distances. However, they are much better at the ability to adjust themselves: a bat can quickly change its direction of flight or pletely reverse it, something a bird cannot easily do.7．犇犇Choose the one that fits best according to the information given in the passage you have just read. 故選B。 （4）考查推理判斷。根據(jù)第四段中的“The fact that the particles landed in the ocean, instead of on land, means larger pieces may have survived and can be studied.”可知，科學(xué)家更喜歡在海洋中尋找流星是因?yàn)樗麄兛赡軙l(fā)現(xiàn)更大的巖石顆粒。故選A。 （2）考查推理判斷。根據(jù)第二段中的“The group says its aim at present is to examine areas of the ocean that have never been explored before.”可知，the Ocean Exploration Trust的船員目前的目標(biāo)是研究海洋中未被探索的地方?？茖W(xué)家更喜歡在海洋中尋找流星是因?yàn)樗麄兛赡軙l(fā)現(xiàn)更大的巖石顆粒。這些物體是在美國太平洋沿岸發(fā)現(xiàn)的。D.Stress the importance of the event.B.Offer clues for the search.D.They may find bigger rock particles.C.They can find meteors more easily.D.Business value of meteors.C.To examine creatures of the explored ocean.（2）What mainly caused the start of the search in the sea? A.To study unexplored places of the ocean.B. The objects recovered from the bottom of the sea likely came from the recent explosion for two main reasons. First, meteorite particles are basically made of glassy materials that do not tend to last long in seawater. Secondly, they came from what looked like a small hole on the seafloor. Some evidence shows that they came from something that fell.（1）What is the current goal of the crew of the Ocean Exploration Trust? A. The search was launched after US government weather stations observed a large meteorite exploding some months ago. The explosion lit up the sky and sent the rock particles to the earth. The meteorite fall was the largest recorded over the United States in at least 20years. The team includes scientists from NASA, the Olympic Coast National Marine Sanctuary and the University of Washington. The scientists examined what they believe were two small meteorite fragments. Further testing is needed before they can confirm that the material came from the explosion. Scientists have found what they believe are pieces of a meteor(流星)that fell to the earth last year. The objects were discovered off the coast of the United States in the Pacific Ocean. 【點(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測和推理判斷三個(gè)題型的考查，是一篇科研類閱讀，要求考生準(zhǔn)確捕捉細(xì)節(jié)信息，同時(shí)根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。由此可知。free land on Earth is used for agriculture, and according to some estimates, producing food accounts for roughly a fifth of all human173。 （3）考查細(xì)節(jié)理解。由此推斷出劃線詞所在的句子意思是我們所吃的食物給環(huán)境帶來了巨大代價(jià)。caused greenhouse gas emissions.
