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?？芍?，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．犇犇閱讀理解 In our twenties, we find it funny when we can39。t remember our neighbor39。s cat39。s name or a handsome actor who starred in a famous movie. In our thirties, we jokingly call it brain freeze. In our forties, we laugh it off as a senior moment and follow up with one of these old age jokes. But the reality is that there es a point when being forgetful stops being funny and starts to seem a bit dreadful. You think, Am I losing it？Or worse, Is this a sign of Alzheimer39。s disease（老年癡呆癥）？ Well, don39。t worry. The fact that you recognize your own forgetfulness may be a very good sign, at least in terms of the possibility of your developing Alzheimer39。s disease（AD）. The researchers in a new study show that it39。s not forgetfulness but not being aware that we39。re forgetful that we should fear. The researchers began with the assumption that one mon feature of Alzheimer39。s disease is a damaged awareness of illness. And they wanted to prove their theory that the lack of awareness can be used to predict whether someone with mild cognitive（認知的）damage will progress to fullon AD. For the study, mild cognitive damage was defined as someone whose mental state was considered healthy but who had either plain
