My Unforgettable Travel

  Besides going by car, there are three other ways to get across the country:planes, trains and buses.Air travel is the most expensive of the three but in many ways the easiest and most comfortable.There are hundreds of flights a day criss-crossing the country, and it is easy to make an order.You will get to your destination(目的地)quickly and find the services(服务)at the airports excellent.There will be connecting bus services to the center of town, car rental agencies and porters(出租公司和搬运工).

  Traveling by train is cheaper than by airplane.In the past, train service was poor but in recent years the government has changed the service with AMTRAK, the nationalized train system.You can travel first or second class.Your ticket is for the journey only, sleeping and dining conditions will be extra.The most inexpensive way to travel is by bus.Continental railways and Greyhound can buy special tickets that allow you unlimited travel for a certain period of time.In this way you can stop along the way to visit the places that interest you most.

  If you do travel long distances, be ready for the time changes.There are four time zones(时区)in the continental USA, starting on the East Coast with Eastern Standard Time(EST), then moving west to Central Standard Time(CST), Mountain Standard Time(MST).If you travel east to west, you gain one hour each time you enter a new time zone.

  Seeing America by Car

  A good way to see the USA is by car.Americans love their cars and in the past fifty years they have developed a vast network of roads and freeways to help them reach their destinations.

  As few visitors have their own cars, renting one is the next best thing.You will need a valid driver’s license(it is best to have an international driver’s license)and either international credit cards(信用卡)(Diners, American Express), or a deposit(存折).

  You should start out with a working knowledge of the road.You travel from state to state and this can be very exciting to a newcomer.For example, in some states it is legal(合法)to turn right at a red light if there is no closing traffic, while in other states you will be fined(罚款)for this action.

  People can enjoy vast(广袤的)areas of wild beauty.Throughout the country, animal and plant life is now protected by law, Americans are learning to be conservationists(天然资源保护者).

Despite all the reports of Internet security attacks over the years, including the recent ones on Google’s e-mail service, many people have reacted to the break-ins with a shrug(耸肩).
  Mr. Shulman and his company examined a list of 32 million passwords that an unknown hacker stole last month from RockYou, a company that makes software for users of social networking sites like Facebook and MySpace. The list was briefly posted on the Web, and hackers and security researchers downloaded it.
  The list provided an unusually detailed window into computer users’ password habits. Typically, only government agencies like the F.B.I. or the National Security Agency have had access to such a large password list.
  Some Web sites try to keep back the attackers by freezing an account for a certain period of time if too many incorrect passwords are typed. But experts say that the hackers simply learn to trick the system, by making guesses at an acceptable rate, for instance.
  To improve security, some Web sites are forcing users to mix letters, numbers and even symbols in their passwords. Others, like Twitter, prevent people from picking common passwords.
  Still, researchers say, social networking and entertainment Web sites often try to make life simpler for their users and are reluctant to put too many controls in place.
  Even commercial sites like eBay must weigh the consequences of freezing accounts, since a hacker could, say, try to win an auction(拍卖) by freezing the accounts of other potential buyers.
  But owing to the reality of our overcrowded brains, the experts suggest that everyone choose at least two different passwords — a complex one for Web sites where security is vital, such as banks and e-mail, and a simpler one for less risky places, such as social networking and entertainment sites.
  Mr. Moss relies on passwords at least 12 characters long, figuring that those make him a more difficult target than the millions of people who choose five- and six-character passwords.
  “It’s like the joke where the hikers run into a bear in the forest, and the hiker that survives is the one who outruns his companions,” Mr. Moss said. “You just want to run that bit faster.
59.   The underlined sentence “Many people have reacted to the break-ins with a shrug” shows that many people ______.
don’t take seriously the hacker’s break-ins
are worried and frightened at the hacker’s break-ins
don’t know what to do with the hacker’s attacks
are eager to get helps from the experts
60.   According to the passage, which of the following web sites needs a more complex password?
A social web site.
An entertainment web site.
A commercial web site.
A government web site.
61.   The Internet users are advised to______ in order to keep back the hackers.
mix letters, numbers and symbols as well
choose passwords with at least 12 characters
choose passwords with 5 or 6 characters
choose at least two different passwords
62.   Which would be the best title for the passage?
Password, Simple or Complex?
Popular Passwords, High Risk!
Clever Hackers, Stupid Netizens.
Hacker, the Enemy of Internet Security.

阅读下面短文,从每题所给的四个选项(A,B,C和D)中选出最佳选项。

If you have made an agreement to go out to eat with someone, you should be clear who is paying. If the other suggests you have lunch with him or her, you might simply say something like this:“I'm afraid it'll have to be some place inexpensive as I have very little money.”The other person may say,“OK, I'll meet you at McDonald's.”This means it is agreed that each person pays for his own meal, i. e. that you “go Dutch”. If the person says,“Oh, no. I'll take you to lunch in a little restaurant I like very much,”it means that the person wants to pay the bill for both of you. If you feel friendly towards this person, there's no reason why you should not accept this invitation by simply saying “Thank you. That would be very nice.”If a person invites you to his or her home for a meal, it's understood that person is paying. If you invite someone to your home, it's understood that you are buying the food. If you want to invite someone out for lunch, you must also make yourself clear by saying, perhaps,“I'd like to take you to lunch tomorrow at the Hostess Inn Coffee Shop”(meaning you plan to buy the food) or“let's have lunch together tomorrow at Burger King. It's on me.”American women used to expect men to pay for all meals, but today most women will pay for themselves. However, you should always make your position clear. Being clear is the polite thing to do. It is lack of clarity (明了) that causes loss of face in this situation.

1.According to the passage, if someone asks you to go out to eat, ________.

[  ]

A.it shows he wants to pay for you

B.it doesn't necessarily meant that he wants to pay for you

C.you should ask him to go out to eat next time

D.you should refuse him if you don't like him

2.The underlined part“go Dutch”means ________.

[  ]

A.each paying for himself

B.buying the food at a store

C.paying for the two of you

D.going to some inexpensive place

3.Which of the following is true according to the passage?

[  ]

A.Men are expected to pay for women when they are eating out.

B.One should accept another person's invitation if he isn't one's good friend.

C.“It's on me.”means“I'll pay for the meal.”

D.If you are invited to someone's house for a meal, you should bring some gifts.

3.In order not to lose face, ________.

[  ]

A.one should try to pay for others

B.one should not eat out without carrying a lot of money

C.one shouldn't let a woman pay for him

D.one should make oneself clear and understood

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有一项为多余选项。
A. Goods for auction (拍卖) sales
  B. Definition of bidding
  C. Way to sell more goods by auction
  D. Auction sales in history
  E. Brief introduction to auctions
  F. Making a larger profit as an auctioneer
【小题1】______
Auctions are public sales of goods, conducted by an officially approved auctioneer. He asks the crowd assembled in the auction-room to make offers, or “bids”, for the various items on sale. He encourages buyers to bid higher figures, and finally names the highest bidder as the buyer of the goods. This is called “knocking down” the goods, for the bidding ends when the auctioneer strikes a small hammer on a table at which he stands.
【小题2】 ______
The ancient Roman probably invented sales by auction, and the English word comes from the Latin auction, meaning “increasing”. The Romans usually sold in this way the goods taken in war. In England in the eighteenth centuries, goods were often sold “by the candle”: a short candle was lit by the auctioneer, and bids could be made while it stayed alight.
【小题3】 ______
Practically all goods whose qualities vary are sold by auction. Among these are coffee, skins, wool, tea, furs, silk and wines. Auction sales are also usual for land and property, furniture, pictures, rare books, old china and similar works of art.
【小题4】 ______
An auction is usually advertised beforehand with full particulars of the articles to be sold and where and when they can be viewed by potential buyers. If the advertisement cannot give full details, catalogues are printed, and each group of goods to be sold together, called a “lot”, is usually given a number. The auctioneer need not begin with Lot 1 and continue in the order of numbers: he may wait until he notices the fact that certain buyers are in the room and then produce the lots they are likely to be interested in.
【小题5】 ______
The auctioneer’s services are paid for in the form of a percentage of the price the goods are sold for. The auctioneer therefore has a direct interest in pushing up the bidding as high as possible. He will not waste time by starting the bidding too low. He will also play on the opponents among his buyers and succeed in getting a high price by encouraging two business competitors to bid against each other.
