【文章內(nèi)容簡介】 e now rarely seen and may migrate further offshore. Males pete for mates either by physical fight or by song. Females give birth to their young every two to three years。 some nonbreeding females probably remain in the southern waters during winter. Young humpback whales return to their area of birth but in later life some wander between breeding areas. Humpbacks eat small shrimps and other schooling prey, such as fish, forming small, cooperative groups of two to three individuals to feed. Similar species: Easily identifiable due to a 39。hump39。 back when submerging, but at a distance may be confused with other species that raise their flukes when diving, such as sperm, right and blue whales. Protection status: Recovering well from past whaling and now numerous in some former migration and aggregation areas, rarely seen in others.（1）Which of the following is TRUE about humpback whales? A.Their long flippers vary in length, size and shape like dorsal fin.B.They are large and likely to grow longer than 15 metres.C.The different colors and patterns of the body help to be recognized.D.Their bumpy tubercles and blowholes are on both sides of head.（2）Which of the following can be inferred from this article39。s description of humpback whales39。 migration? A.They need warmer waters to breed.B.They can39。t survive in extreme cold.C.They find plentiful food in tropical waters.D.They are mostly hunted in New Zealand waters.（3）This article is mainly intended to . A.explain why humpbacks are still hunted in some parts of the worldB.introduce how humpbacks migrate through some dangerous watersC.popularize the basic knowledge of humpbacks and call for protectionD.help distinguish humpbacks from other similar species【答案】 （1）C（2）A（3）C 【解析】【分析】本文是一篇說明文，介紹了座頭鯨外形特點、體重、顏色，以及其如何繁殖、喂養(yǎng)等生活習性等，并呼吁大家保護它。 （1）考查推理判斷 。根據(jù)第四個小點后的一段Body color is dark brown to black。 often extensive white on flippers and underside of body and flukes。 such patterns enable individual recognition可知，座頭鯨體色由深棕色至黑色，腳蹼、身體底部和尾鰭上通常是大面積的白色；這樣的圖案使單個的座頭鯨很容易被識別。分析選項可知C項符合題意，故選C。 （2）考查推理判斷。根據(jù)第五個小黑點后面的The big family migrate between winter tropical breeding areas (North West Shelf, Great Barrier Reef, New Caledonia, Vanuatu, Fiii, Tonga) and summer Antarctic feeding areas. 座頭鯨這個大家族在冬季的熱帶繁殖區(qū)（西北大陸架、大堡礁、新喀里多尼亞、瓦努阿圖、斐濟、湯加）和夏季南極喂養(yǎng)區(qū)之間遷徙。可知，座頭鯨在熱帶地區(qū)繁殖。冬季的熱帶繁殖區(qū)，是溫暖的地方?？芍^鯨需要在暖和的地方繁殖，故選A。 （3）考查主旨大意。本文主要對座頭鯨外形特點、體重、顏色，以及其如何繁殖喂養(yǎng)等生活習性等作了介紹，并呼吁大家保護意識。所以本文目的是普及有關(guān)座頭鯨的知識，并對它們加以保護。分析選項可知C項符合題意，故選C。 【點評】本題考點涉及推理判斷和主旨大意三個題型的考查，是一篇科普類閱讀，要求考生根據(jù)上下文的邏輯關(guān)系，進行分析，推理，概括和歸納，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】本文是一篇說明文，介紹了一款由美國華盛頓州立大學的科學家們研發(fā)的機器人，可以幫助那些癡呆或有身體缺陷的老年人在家里過上自立的生活。 （1）考查細節(jié)理解。根據(jù)章第二段中的“ The Robot Activity Support System, or RAS, uses sensors （傳感器）equipped in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with da
