【文章內(nèi)容簡介】 meteorites from drilling operations. 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.To recover the rock particles.B.To observe movements of the universe.C.To study unexplored places of the ocean.D.To examine creatures of the explored ocean.（2）What mainly caused the start of the search in the sea? A.A huge meteor shower.B.Business value of meteors.C.Plenty of natural resources.D.The brainstorm of researchers.（3）Why do the scientists prefer to search for meteors in the ocean? A.They can find meteors more easily.B.They may find bigger rock particles.C.They like to explore strange sea areas.D.They have better submarine equipment.（4）What does the author intend to do in the last paragraph? A.Offer clues for the search.B.Give reasons to support a guess.C.Stress the importance of the event.D.Describe the process of the search.【答案】 （1）C（2）A（3）B（4）B 【解析】【分析】本文是一篇說明文，科學(xué)家們發(fā)現(xiàn)了他們認(rèn)為是去年墜落地球的流星碎片。這些物體是在美國太平洋沿岸發(fā)現(xiàn)的。一場巨大的流星雨導(dǎo)致了在海中搜索的開始。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。 （1）考查細(xì)節(jié)理解。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。故選C。 （2）考查推理判斷。根據(jù)第一段中的“Scientists have found what they believe are pieces of a meteor(流星)that fell to the earth last year.”可知，一場巨大的流星雨導(dǎo)致了在海中搜索的開始。故選A。 （3）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B。 （4）考查推理判斷。根據(jù)最后一段中的“The objects recovered from the bottom of the sea likely came from the recent explosion for two main reasons.”可知，作者在最后一段是想給出支持猜測的理由。故選B。 【點(diǎn)評】本題考點(diǎn)涉及細(xì)節(jié)理解和推理判斷兩個題型的考查，是一篇科普類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。5．閱讀理解 A robot created by Washington State University (WSU) scientists could help elderly people with dementia (癡呆) and other limitations live independently in their own homes. The Robot Activity Support System or RAS, uses sensors installed in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities. It navigates (定位) through rooms and around obstacles to find people on its own, provides video instructions on how to do simple tasks and can even lead its owner to objects like their medication or a snack in the kitchen.RAS bines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment, as the need for help is detected, said Bryan Minor, a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science. Currently, an estimated 50 percent of adults over the age of 85 need assistance with every day activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly $2 trillion. With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial strain on the healthcare system by making it easier for older adults to live alone. RAS is the first robot researchers have tried to incorporate into their smart home environment. They recently published a study in the journal Cognitive Systems Research that demonstrates how RAS could make life easier for older adults struggling to live independently. While we are still in an early stage of development, our initial results with RAS have been promising, Minor said. The next step in the research will be to test RAS39。 performance with a group of older adults to get a better idea of what prompts, video reminders and other preferences they have regarding the robot.（1）How does RAS serve elderly people? A.Through sensors.B.Through objects.C.Through a mobile robot.D.Through their daily activities.（2）What can we know about RAS? A.It is the first robot used in daily life.B.Its function remains to be tested.C.It can locate people and do any task.D.It can cook for owners on its own.（3）What39。s Minor39。s attitude toward the future of RAS? A.Doubtful.B.Negative.C.Optimistic.D.Uncertain.（4）What can be a suitable title for the text? A.Elderly people leave the nursing home.B.Smart Home Tests first elderCare robot.C.RAS, the first robot to make home smart.D.Older adults have benefited from RAS.【答案】 （1）A（2）B（3）C（4）B 【解析】【分析】
