必修1 Unit 4 Earthquakes 课时作业 高效提能

单独成册：对应学生用书第223页 Ⅰ.阅读理解 A Mandara seemed to know something big was about to happen.So she let out a yell，caught hold of her 2-year-old daughter Kibibi and climbed up into a tree.She lives at the National Zoo in Washington，D.C. And on Tuesday，August 23rd，witnesses said she seemed to sense the big earthquake that shook much of the East Coast before any humans knew what was going on.And she's not the only one.In the moments before the quake，an orangutan (猩猩)let out a loud call and then climbed to the top of her shelter. “It's very different from their normal call，” said Brandie Smith，the zookeeper.“The lemurs(monkey-like animals of Madagascar)will sound an alarm if they see or hear something highly unusual.” But you can't see or hear an earthquake 15 minutes before it happens，can you？Maybe you can—if you're an animal.“Animals can hear above and below our range of hearing，” said Brandie Smith.“That's part of their special abilities.They're more sensitive to the environment，which is how they survive.” Primates weren't the only animals that seemed to sense the quake before it happened.One of the elephants made a warning sound.And a huge lizard(蜥蜴)ran quickly for cover.The flamingoes(a kind of birds)gathered before the quake and stayed together until the shaking stopped. So what kind of vibrations(震动)were the animals picking up in the moments before the quake？Scientist Susan Hough said earthquakes produce two types of waves—a weak “P” wave and then a much stronger “S” wave.The “P” stands for “primary”．And the “S” stands for “secondary”．She thinks the “P” wave might be what sets the animals off. Not all the animals behaved unusually before the quake.For example，Smith said the zoo's giant pandas didn't jump up until the shaking actually began.But many of the other animals seemed to know something was coming before it happened.“I'm not surprised at all，” Smith said. [语篇解读] 本文是一篇说明文。文章主要介绍了一些动物在地震来临前的反应。 1．Why did Mandara act strangely one day? A．Because it sensed something unusual would happen. B．Because its daughter Kibibi was injured. C．Because it heard an orangutan let out a loud call. D．Because an earthquake had happened. 解析：细节理解题。根据文章第一段第一、二句“Mandara seemed to know something big was about to happen.So...into a tree.”可知，它察觉到会发生非同寻常的事。故选A。 答案：A 2．According to Brandie Smith，________． A．many animals' hearing is sharp B．earthquakes produce two types of waves C．primates usually gather together before a quake D．humans can also develop the ability to sense a quake 解析：细节理解题。根据第四段中的“‘Animals can hear above and below our range of hearing，’said Brandie Smith.”可知，动物的听觉是很敏锐的。故选A。 答案：A 3．Which animal seems unable to sense a quake? A．A giant panda. B．A flamingo. C．A lemur. D．A lizard. 解析：细节理解题。根据最后一段中的“...Smith said the zoo's giant pandas didn't jump up until the shaking actually began.”可知，大熊猫在地震之前是没有异常反应的。故选A。 答案：A 4．What is the best title for the passage? A．How Animals Survive a Quake B．How Animals Differ from Humans C．How Animals Behave before a Quake D．How Animals Protect Their Young in a Quake 解析：标题归纳题。本文主要说的是地震发生前一些动物的表现。故选C。 答案：C B If you ever visit an English village，make sure to look out for morris dancing. Undoubtedly as one of the strangest of English culture，morris dancing is a form of folk dancing that dates back to the 15th century.If you ever get the opportunity，you really have to see it. Men and women wearing old-fashioned，tattered(破烂的)clothing dance in the street of towns and villages across the country during the holiday periods.Women wear long，frilly(有褶边的)skirts and men wear short trousers with bells attached to them.They dance to traditional folk music which is often played on traditional musical instruments. Some groups carry heavy black sticks with which they bash against each other while they dance.Other groups wave handkerchiefs in the air whilst they perform.The dances are usually performed near a pub so that when it's over，the dancers and audience can sing some traditional folk songs over a pint of beer.The festivities will often continue long into the night，by which point most people are too drunk to think about performing again. Morris dancing is a great English tradition but it's facing a big crisis.As the years go by，fewer and fewer young people are joining morris dancing groups.The dancers are getting older and older and eventually，if nothing is done to change this trend，the tradition will die out within the next few decades. If you've ever had the fortune to see morris dancing，you may understand why
