Stocky, slowmoving whale, rarely grows beyond 15 metres in length Flippers are a third of body length。 variable dorsal fin size and shape。 sawtoothed trailing edge on flukes, often raised when diving Bumpy tubercles on top of head Body colour is dark brown to black。 often extensive white on flippers and underside of body and flukes。 such patterns enable individual recognition Bushy blow, occasionally Vshaped 270400 olive baleen plates Humpback whales belong to the rorqual (groovethroated) family, which includes fin, sei, Bryde39。s, minke and blue whales. 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. Once mon in New Zealand waters, humpbacks are 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(shuō)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?？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(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(lèi)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
