2.Harry Potter fans will instantly recognize the snowy owl as Harry’s famous companion.Hedwig，but these beautiful and powerful owls are easily recognizable not for their magicalassociations，but for their large size and striking white feathers.Snowy owls are，in fact，theonly white owl，and they are a highly sought after species for many birdwatchers to add to theirlife lists.Foods：Small mammals，birds，fish.Habitat and Migration：Snowy owls are found in far northern latitudes including tundra，avasttreeless frozen region in the Arctic.Their breeding grounds(繁殖地)are in the Arctictundra，and they migrate south throughout Canada during the winter.In exceptionally severewinters or whenfood supplies are scarce，these owls can appear much further south than theirnormal range.While principally a North American bird.they can also migrate to the northernareas of Europe and Asia.Behaviour：Snowy owls，like aⅡowls，are powerful animal hunters that are active mostlyat night but Call bunt and feed during the day，especially when food supplies are low.Theseowls will rest on the ground or on rocks，stumps and other low favourable points.Males can befierce whendefending the nest and both genders will also perform an“injured bird”act totempt animal invadeTs to go away from the nest.Reproduction：Snowy owls may incubate(孵卵)3—10 eggs for 30—34 days，or theincubation may be done primarily by the female.The baby owls remain in the nest for 14—21days and will attempt their first flight when they are 42—58 days old.Mated pairs will raiseone group of young birds per year unless food supplies are inadequate and then no eggs may beproduced.For snowy owis，one way to detend their nest is.

3.Whatever you do, don’t challenge a chimpanzee named Ayumu to a number memory game. In 2007, Ayumu became famous for his lightning speed at a game that goes like this: A player views a computer screen where the numbers 1 through 9 appear briefly at once and then turn to white squares.The player then taps the squares where the numbers had been, in order from 1 to 9.People can do it.But no human competitor has ever completed the game faster or more accurately than Ayumu the chimp.For almost five years Ayumu remains undefeated.Psychologist Nicholas Humphrey of Darwin College at Cambridge University in England now thinks he knows the secret behind the chimp’s ability.Humphrey suspects Ayumu’s brain may have a condition that allows the chimp to see numbers as colors.This would mean that Ayumu may see a color glow after the numbers disappears.Then, instead of remembering the numbers, he remembers a sequence of colors, each associated with a number.The condition that Humphrey believes Ayumu may have is called synesthesia.Humans withsynesthesia may associate numbers and letters with colors.For example, a person may see thenumber “5” as the color blue.Until now, scientists had assumed only humans could havesynesthesia.Humphrey found the inspiration for his idea at a 2011 scientific conference.There, he heard apresentation about Ayumu’s memory abilities and another talk about synesthesia.He then put the two ideas together.Not everyone is convinced that Humphrey is correct.Primatologist Tetsuro Matsuzawa of thePrimate Research Institute at Kyoto University in Japan has spent decades studying the amazingmemories of chimpanzees, including Ayumu.He maintains that chimps simply have faster memory recall than people.What is Ayumu famous for?

4.Debate is a valuable way to practise communicating. It can also bring long-lastingrewards,especially for people working with Western businesses. The main activity of debate ispresenting one' s opinion and suppmting it with evidence,such as statistics or facts. It is a way ofpersuasive communication.Charles Lebeau helped create the "Discover Debate" method. He says debate is important tounderstanding how people communicate in Western business. Successful debaters learn how togive their opinkm,reasans and support. "What we are trying to do is to develop a kind of thinkingor approach to discussion and how to interact (交流) with someone else' s opinion, rather thanbrush their opinion aside. "Debate skills are also important in selling a product, he says. In that situation, the judges are the customem. "So on Monday, for example, one company may come in and present their case to the customer and they" ll make as strong a ease as they can. On Tuesday, the next day, anothercompany will come in and present their ease to the customer. Usually the party that can presentthe strongest case wins”Debate also strengthens critical thinking. In other words, it helps students learn to askquestionsand try to understand someone' s reasons and evidence.lift-. Lebeau points out thatsuccessful debaters learn to listen carefully to what other people are saying. Then, they look forthe weak points in someone else' s opinion or argument. He says debate teaches a systematic way of questioning.Successful debaters also learn to think from someone else' s point of view. Mr. Lebeau says debate can help broaden the mind. "There' s an expression in English : don' t criticize another person before you have walked in their shoes. I think the wonderful thing about debate is, it puts us in another person' s shoes. "What does the underlined word "case" in Paragraph 3 refer to?

5.Compare the underlined parts and iden-tify the one that is different from the others in pronunciation.

6.One of the most interesting experiments in electronic communication I’ve ever seen is coming from Wave. It’s real-time e-mail,What that means is that as you’re typing a message in Wave,either a new massage or a reply ,the person you are writing to can see what you’re typing as you type it .Sounds awful, right?You don’t have to use W ave in this real-time way . It also works as a standard e-mail. What’s really different about Wave is that if you’re replying to a massage and the person you’re replying to happen to be online,they can jump into the conversation at that point, and change what is an emailconversation into an instant message conversation or a chat.Wave right now is still closed to most users . And Wave isn’t yet connected to other communication systems,like regular e-mail , which means that the only people we can Wave with are other people on waves as well. So we don’t yet know what using Wave will be like once it gets crowded like e-mail . Also,the technology behind Wave is far more demanding on servers and the Internet itself than regular e-mail or chat,so we don’t know if the technology will work at scale .But Wave really is a current re-think of e-mail . A lot of people won’t like it . A lot of people didn’t like e-mail either when it first showed up .but people will find real uses for Wave or whatever it becomes, and it’s one of the most interesting new takes on communication . Even if you don’t like it, it will make you think differently about e-mail.What is the auther’s attitude toward Wave?

13.Romeo and Juliet was probably written in 1595, when Shakespeare was a young successfulplaywright. He had already written comedies and history plays, but had not yet developed his shill in tragedy.The power of fate is strong to Shakespeare’s play. Chance and evil eventually join to bring tragedy.Chance involves Romeo in a murder, chance prevents a message from reaching Romeo in time, chance brings about a deadly meeting in a cemetery.Many Elizabethans were followers of astrology(星相术) and believed that the stars could control events. Thus, Romeo and Juliet art referred to as” star-crossed lovers” whose stars doomed(命中注定)them to disaster.Elizabethans also had a concept of fate in the person of Dame Fortune (命运女神). By spinning her wheel, she could raise the state of a beggar or a lower that of a king. One of the fascinations of Shakespeare is the way in which he put these ideas into the play.One of the most difficult things to decide about this play is the question of responsibility. Didirresistible fate bring tragedy to Romeo and Juliet, or were they themselves to blame? The fact that this question is not resolved by the author also helps to make Shakespeare’s Romeo and Juliet a fascinating work.What is unresolved about this play is ____.

14.I used to go with him but he had such a __________time trying to persuade people even to see him that I seldom had to do any tests.请选择最佳答案()。

19.The Saturday Evening Post "became symbolic of the reading fare of middle-class America". In 1897 Curtis began to revive (重振) the Post on the proposition that a man's chief interest in life is the fight for livelihood -- business. Fiction and articles about romantic business and successful businessmen filled its pages, and products backed by its advertisements directed at the needs and desires of the business world. The general interest weekly reached new audiences. Its conservative viewpoint and strong admiration for material success appealed to the tastes of the millions who settled in an easy chair with it each Thursday evening. As a more commercial, mass-circulation magazine than The New Yorker, the widely readable Post set out to interpret America to itself.As a national and international institution, The Saturday Evening Post made its mark in the lives of massive numbers of men and women, and served society as a stabilizing influence. Its editorial matter addressed the problems and interests of the readers as never before. Neither highbrow nor lowbrow, the Post set out to interpret average middle-class America, for that was its audience.However, this magazine lost touch with the mood of the American people in the 1930s. The Post's editor Lorimer, opposed Roosevelt and the New Deal and changed his magazine from an organ of entertainment and enlightenment into a weapon of political warfare. He believed that in opposing the New Deal he had spoken for the majority of voters, but the 1936 election proved him wrong.His conservatism extended beyond politics, it dominated the magazine's content and style causing a decline in reputation and authority. The Post met its greatest success when it went beyond the tastes of the masses, challenging its readers to acknowledge the genius of contributors such as F.Scott Fitzgerald and William Faulkner. It was later reformed in an effort to fulfill its responsibility to awaken lethargic (昏昏欲睡的)America, however, The Saturday Evening Post seemed to play to conventions while The New Yorker took off to redefine the character of American Humor.According to Paragraph 1, who are primarily the readers of the Post?

20.根据以下资料，回答17-20题。 　　California families are facing a rapidly mounting uphill battle to make enough money to provide basic household essentials, according to a new study conducted by the California Budget Project. 　　The research compiled by the Sacramento-based non-profit organization concluded an average two-parent family with one employed adult in California needs to make $51,177 a year, or $24.60 cents an hour, to pay for housing, transportation, food, utilities, child care, health coverage, taxes and other basic expenses. 　　The number grows significantly higher in the Bay Area, the state's most expensive region．A Bay Area family of four with two working adults living in rental housing needs a combined income of $79,946 to cover essential needs．That number is more than four times greater than the $19,157 income level recognized by the federal government as impoverished. 　　The study is the fourth semi-annual survey conducted by the California Budget Project since 1999． California Budget Project executive director Jean Ross said helping state officials and residents understand the numbers found in the report is crucial to moving families toward self-sufficiency. "How should we be targeting some of our programs and policies? How much do young people need to earn and what kind of a job should they be looking to train for if they want to have that salary that can support a family?" 　　CBP said the project was based on actual costs or generally accepted fair standard prices based on weighted averages found in ten California regions.19 How do we know that the costs are rising in California?
