【文章內(nèi)容簡(jiǎn)介】 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(diǎn)、體重、顏色，以及其如何繁殖、喂養(yǎng)等生活習(xí)性等，并呼吁大家保護(hù)它。 （1）考查推理判斷 。根據(jù)第四個(gè)小點(diǎn)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(gè)的座頭鯨很容易被識(shí)別。分析選項(xiàng)可知C項(xiàng)符合題意，故選C。 （2）考查推理判斷。根據(jù)第五個(gè)小黑點(diǎn)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(gè)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(jì)、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。可知座頭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(duì)座頭鯨外形特點(diǎn)、體重、顏色，以及其如何繁殖喂養(yǎng)等生活習(xí)性等作了介紹，并呼吁大家保護(hù)意識(shí)。所以本文目的是普及有關(guān)座頭鯨的知識(shí)，并對(duì)它們加以保護(hù)。分析選項(xiàng)可知C項(xiàng)符合題意，故選C。 【點(diǎn)評(píng)】本題考點(diǎn)涉及推理判斷和主旨大意三個(gè)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(jìn)行分析，推理，概括和歸納，從而選出正確答案。5．犇犇閱讀理解 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. The crew of the Nautilus, a private research ship, recovered the rock particles(顆粒).The Nautilus is operated by the Ocean Exploration Trust. The group says its aim at present is to examine areas of the ocean that have never been explored before. 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. The Nautilus is equipped with two remotely operated vehicles(ROVs), called Hercules and Argus. These robotic submarines help researchers find and collect materials from the seafloor. The fact that the particles landed in the ocean, instead of on land, means larger pieces may have survived and can be studied. For this reason, scientists decided to launch the first intentional search for meteorites from the ocean. Until the latest research, scientists had only accidentally discovered a small number of 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(chǎng)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?huì)發(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(chǎng)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.
