hyenas (鬣狗) are fierce competitors，all seeking out the same prey (捕獲物) and often even stealing each others kills！But dont tell that to these five youngsters who believe that they were born to be best of friends.The special group including three baby lions，one baby tiger and one baby hyena，all born at the Akwaaba Lodge in Rustenburg，South Africa were abandoned (遺棄) immediately by their mothers.Fortunately the owner of the Akwaaba Lodge，Layla Cajee decided to not only raise the young babies，but also，place them in the same room.Not knowing any better，the animals have all become best of friends who spend their whole day playing and nights，cuddled up (依偎) next to each other.Like every young child who is just learning to walk，each one has an obvious personality.According to Layla，the leader of the group is the fivemonthold tiger Bella，who controls everything including trying to get the biggest share during mealtimes.The lionsDelano，Romeo and Maximus who are also five months old，are surprisingly shy.As for sixmonthold Milika，the hyena？She is the naughty and noisy one，always ready to pick a fight with her temporary friends.Temporary，because this group will not last forever.Within about two years，as soon as the animals turn into dangerous predators，they will be given their own living places.But it is thanks to this unusual relationship that they will be able to see that day，because none of them would have been able to survive alone in the wild.What would be interesting to observe is their relationship if they ever meet each other in the wild.Will they compete with each other as fiercely for the same prey as they normally do or，will they remember the fact that they were once friends and share their kill?語篇解讀本文是說明文。文章介紹了由五只被父母遺棄的老虎、獅子、鬣狗組成的特殊團體。1The third paragraph is mainly about the baby animals_.AnamesBcharactersChappy life Dliving habits解析：段落大意題。本段主要介紹了五只小動物的個性，關鍵詞有shy，naughty，noisy等。答案：B2The animals will be separated in the future mainly because_.Ait will be too dangerous for them to live togetherBtheir big sizes wont allow them to stay togetherCthey will have to find their own preyDthey will have to live in the wild解析：細節(jié)理解題。根據第四段中的as soon as the animals turn into dangerous predators，they will be given their own living places可知。答案：A3From the text we can learn that_.AMilika is the leader of the special groupBthe five animals can not survive in the wild right nowCthe animals will compete with each other for the same foodDLayla raised the animals immediately after they were abandoned解析：推理判斷題。根據第四段中的because none of them would have been able to survive alone in the wild可知。答案：B4What would be the best title for the text?ANo longer competitorsBHello，lovely animalsCUnusual friendshipDFierce animals?解析：標題歸納題。由文中出現(xiàn)的friends，special及五只動物之間的關系可知，C項作標題較貼切。答案：CHalf the worlds population could face a shortage of food by 2100 due to climate change，a new report by US scientists warns.Rapid global warming is likely to reduce crop production in the tropics and subtropics (熱帶和亞熱帶地區(qū))，according to Professor David Battisti of the University of Washington.The most extreme summers of the last century will become common，he says.We must immediately create crops that can bear heat and drought if we are to adapt (適應) in time，he writes in Science journal.“The stresses on global food production from temperature alone are going to be huge，” said Mr Battisti.“And that doesnt take into account water supplies stressed by the higher temperatures.”He worked with Professor Rosamond Naylor on Food Security and the Environment，to examine the influence of climate change on the worlds food supplies.They predict there is a greater than 90% probability that by 2100，the average growingseason temperatures in the tropics and subtropics will be higher than any temperatures recorded there to date.“We are taking the worst of what weve seen historically and saying that in the future it is going to be a lot worse unless there is some kind of adaptation，” said Professor Naylor.“This is a powerful reason for us to invest (投資) in adaptation，because it is clear that this is the direction we are going in terms of temperature and it will take decades to develop new food crop varieties that can better bear a warmer climate.”In the tropics，the higher temperatures could be expected to cut production of the primary food crops by 2040%，the researchers said.Rising temperatures are also likely to reduce soil moisture (濕度)，cutting production even further.Three billion people live in the tropics and subtropics now，and their number is expected nearly to double by the end of the century.“You are talking about hundreds of millions of additional people looking for food because they wont be able to find it where they find it now，” said Professor Battisti.Crop failures would not be limited to the tropics，the scientists concluded.語篇解讀根據美國的一項最新報告，全球變暖將帶來農作物的減產，從而導致全球糧食危機。5According to Professor David Battisti，what should be done to deal with crops reduction caused by global warming?ATo plant more crops.BTo develop new crops.CTo control population growth.DTo improve farming technology.解析：細節(jié)理解題。根據第二段We must immediately create crops that can bear heat and drought.可知，David Battisti教授認為，要應對高溫帶來的糧食減產問題，我們必須盡快研發(fā)能耐高溫和干旱的新農作物品種。答案：B6What does it mainly talk about in Para.3?AThe high temperature caused both food and water stresses.BWe cannot solve the problem of either food or water stresses.CThe stress on water in the tropics and subtropics is huge too.DWe only have to deal with the problem of food stress.解析：推理判斷題。第三段說由于溫度本身造成的糧食產量壓力本身就夠大的了，還沒有考慮由于高溫造成的供水壓力，可見A項是正確的。全文沒有提及B項，C項和D項描述片面。答案：A7What does the underlined word “this” in Paragraph 5 refer to?ATo reduce the temperature.BNew food crop variety.CTo invest in adaptation.DSome kind of adaptation.解析：指代題。根據語境可知，這里的this一詞，指代前面提到的結果to invest in adaptation (投資研發(fā)適應高溫干旱天氣的農作物)。答案：C8We can know from the text that_.Athe number of people living in the tropics is reducingBtemperatures will rise most in the tropicsCcrop failures will be a global problemDnew food crop varieties will be developed soon解析：細節(jié)理解題。根據文末Crop failures would not be limited to the tropics可知C項正確。答案：C
