repair the house，a Japanese tore open the walls.Japanese houses normally have an empty space between the wooden walls.When pulling down the walls，he found that there was a lizard(蜥蜴) staying there because a nail(钉子) from outside was hammered into one of its feet.He saw this，feeling pity and curious.When he checked the nail，he found it was nailed 10 years ago when the house was first built.What happened？The lizard had survived in such a position for 10 years! It has been in a dark wall partition(夹层) for 10 years without moving! Then he wondered how this lizard survived for 10 years without moving a single stepsince its foot was nailed! So he stopped his work and observed the lizard：What has it been doing？What and how has it been eating？Later，he didnt know from where another lizard appeared，with food in its mouth.Ah! He was astonished and touched deeply.The free lizard had been feeding it for the past 10 years.Such love，a beautiful love! Such love happened with this tiny creature.What can love do？It can do wonders! Just think about it：one lizard had been feeding the other for 10 long years，without giving up hope on its partner.If a small creature like a lizard can love like this，just imagine how we can love if we try.11How did the Japanese feel when seeing the lizard there?AFrightened. BEnjoyable.CConfused. DUsual.答案C解析推理判断题。根据第一段倒数第二句“He saw this，feeling pity and curious.”可知，这个日本人看见蜥蜴感到很困惑。故选C。12Why did the Japanese stop his work?ATo watch how long the lizard can still live here.BTo take out the nail and set the lizard free.CTo have a rest by watching the lizard.DTo find out why the lizard had survived there for 10 years.答案D解析细节理解题。根据第二段中的“Then he wondered how this lizard survived for 10 years without moving a single stepsince its foot was nailed! So he stopped his work”可知，这个日本人停止工作是为了发现为什么那只蜥蜴(在如此艰难的情况下)能存活10年。故选D。13What can we learn from the free lizard?AIt teaches us never to give up our loved ones.BIt teaches us to give more help to our loved ones.CIt tells us to take pity on the stuck lizard.DIt encourages us to live even longer.答案A解析推理判断题。根据第三段内容可知，这个自由的蜥蜴教我们永远不要放弃我们爱的人。故选A。BAs a seal rests on ice floating on the Antarctic Ocean，it should feel safe.But it is about to become a victim of a group of killer whales who have developed a great skill to catch seals.The killer whales work together as a group to create large waves that wash seals off the ice.Scientists who have discovered the technique，which has only been seen in killer whales hunting in the pack ice of the Antarctic，say it is so effective that it produces a meal for the whales three out of every four times they use it.Dr.Robert Pitman，a marine scientist at the National Oceanic and Atmospheric Administration in California，said，“The killer whales were very good at knowing in advance if they were going to be able to wash a seal off a piece of ice and they were always successful in getting the seal into the water.Sometimes the seal was washed off but managed to flee.However，it was not very often.”Dr.Pitman and his colleague Dr.John Durban helped BBC capture the wavewashing behaviour on camera.By swimming in formation(队列) towards the ice from as far away as 150 feet，the whales created a bow wave in front of their bodies.When they reached the block of ice where the seal was hiding，they dove under the ice，kicking their tails in a powerful stroke(击) to create a largewave that washed over the ice and knocked the seal into the water where they could grab it and drown it.Research has shown that there are at least four types of killer whales living in the Antarctic，all of which have different colour patterns and hunting behaviour，and eat different things.The largest killer whale hunts minke whales(小须鲸) in open water while the ice killer whales mainly hunt seals.A third type of killer whale mainly preys on penguins and the fourth dives deep to hunt fish.14According to Paragraph 1，killer whales hunt a seal on a piece of ice by .Apushing the ice onto the groundBknocking hard on the ice togetherCcreating large waves to wash it off the iceDfollowing it all the time until it swims in the sea答案C解析细节理解题。根据第一段最后一句“The killer whales work together as a group to create large waves that wash seals off the ice.”可知这种鲸鱼通过制造大浪把海豹从冰上冲刷下来，然后捕食它们。15It is implied in the passage that .Akiller whales often stay hungryBkiller whales usually hunt aloneCcompetition among killer whales is very fierceDkiller whales are very good at hunting seals at sea答案D解析推理判断题。根据第二段中的“.it is so effective that it produces a meal for the whales three out of every four times they use it.”以及第三段中的“.they were always successful in getting the seal into the water.”可推断这种鲸鱼很擅长捕食海豹。16What does the underlined word “flee” in Paragraph 3 most probably mean?AMove. BEscape.CStruggle. DFight.答案B解析词义猜测题。根据but的语境可知，有时候海豹也会成功地“逃脱”。17What is Paragraph 4 mainly about?AHow Dr.Pitman and his colleague work.BHow killer whales find seals.CHow killer whales hunt seals.DHow killer whales eat a seal.答案C解析段落大意题。通读第四段可知，主要是通过镜头来告诉我们这种鲸鱼是如何成功猎捕海豹的。.七选五Easy Ways to Keep Your Brain SharpEveryone is forgetful，but as we age，we start to feel like our brains are slowing down a bitand that can be a very annoying thing. 18 Read on for some techniques wor
