【題目】Is there something that you’ve always wanted to try but just never had the time？Well, make plans to try it now since you are on summer vacation. Not all vacations call for taking a tour bus to take photos of famous landmarks. Some vacations allow you plenty of opportunities to learn.

The most difficult aspect of a learning vacation may be choosing one because the possibilities are endless. If you enjoy cooking，various companies can take you to Italy, France, Spain, Mexico or even Peru. Once there, you can learn to prepare the local cuisine(烹飪). Trips are often planned to fit in with local food festivals or special events.

The term “l(fā)earning vacation” often brings language to mind. The best way to learn a language is in an environment where it’s spoken. Study Spanish, French or English. Or attempt a more unusual language like Polish, Estonian or Thai. You’ll be able to learn about the country and absorb the culture at the same time. In that case, you can really learn the authentic foreign language.

If you are fond of sports, you can polish your skills or learn new ones. Golf and tennis schools welcome players of all levels. If you want a bigger thrill, you can learn to surf, go climbing or race cars. It’s even possible to learn the art and techniques of bull fighting while on vacation!

You can also discover your inner artist. Many places offer painting classes in different mediums. The scenic locations of the schools offer plenty of subjects that provide inspiration for practice.

If you prefer capturing the world on film, take a photography vacation. Travel with a small group to photograph beautiful animals or scenery. You can also practice your technique on people or at historical sights.

Once you decide on a vacation, choose a company carefully. Request names of recent customers you can contact, and then ask them for an evaluation. The more you know before you go, the better prepared you’ll be. Then go out and learn something!

【1】Why is it hard for you to decide on a learning vacation?

【題目】The Swiss army knife is a popular device that is recognized all over the world. In Switzerland, there is a saying that every good Swiss citizen has one in his or her pocket. But the knife had poor beginnings.

In the late nineteenth century, the Swiss army issued (發(fā)給) its soldiers a gun that required a special screwdriver (螺絲刀) to take it apart and clean it. At the same time, canned food was becoming common in the army. Swiss generals decided to issue each soldier a standard knife to serve both as a screwdriver and a can opener.

It was a lifesaver for Swiss knife makers, who were struggling to ask for cheaper German imports. In 1884, Carl Elsener, head of the Swiss knife manufacturer (maker) Victorinox, seized that opportunity with both hands, and designed a soldier’s knife that the army loved .It was a simple knife with one big blade (刀片), a can opener, and a screwdriver.

A few years after the soldier’s knife was issued, the “Schweizer Offizer Messer,” or Swiss Officer’s Knife, came on the market, Interestingly, the Officer’s Knife was never given to those serving in the army. The Swiss army purchasers considered the new model with a corkscrew (瓶塞鉆) for opening wine not “essential for survival,” so officers had to buy this new model by themselves. But its special multi-functional design later launched(發(fā)行)the knife as a global brand. After the Second World War, a great number of American soldiers were stationed in Europe. And as they could buy the Swiss army knife at shops on army bases, they bought huge quantities of them. However, it seems that “Schweizer Offizer Messer” was too difficult for them to say, so they just called it the Swiss army knife, and that is the name it is now known by all over the world.

【1】What is the main purpose of the passage?

A. To emphasize the importance of the Swiss army knife.

B. To introduce the functions of the Swiss army knife.

C. To explain the origin of Swiss army knife.

D. To tell a story about the designer of the Swiss army knife.

【2】What does “It” in the third paragraph refer to?

A. Canned food was becoming popular in Swiss army.

B. Every good Swiss citizen had a knife in his pocket.

C. The Swiss army needed a knife for every soldier.

D. Swiss knives were competing with imported knives.

【3】Why didn’t the Swiss army purchase the Swiss Officer’s Knife?

A. The new design was not considered necessary for officers to own.

B. The army had no budge to the purchase.

C. The knife was sold out to American soldiers.

D. The design of the knife was too simple.

【4】Who gave the name “ the Swiss army knife” to the knife discussed in the passage?

A. Swiss generals B. Carl Elsener

C. German businessman D. American soldiers.

【題目】Sports account for a growing amount of income made on the sales of commercial time by television companies. Many television companies have used sports to attract viewers from particular sections of the general public，and then they have sold audiences to advertisers.

An attraction of sport programs for the major U. S. media companies is that events are often held on Saturday and Sunday afternoons—the slowest time periods of the week for general television viewing. Sport events are the most popular weekend programs, especially among male viewers who may not watch much television at other times during the week. This means the television networks are able to sell advertising time at relatively high prices during what normally would be dead time for programming.

Media corporations also use sports to attract commercial sponsors that might take their advertising dollars elsewhere if television stations did not report certain sports. The people in the advertising departments of major corporations realize that sports attract male viewers. They also realize that most business travelers are men and that many men make family decisions on the purchases of computers, cars and life insurance.

Golf and tennis are special cases for television programming. These sports attract few viewers, and the ratings (收視率)are unusually low. However, the audience for these sports is attractive to certain advertisers. It is made up of people from the highest income groups in the United States, including many lawyers and business managers. This is why television reporting of golf and tennis is sponsored by companies selling high-priced cars，business and personal computers，and holiday trips. This is also why the networks continue to carry these programs regardless of low ratings. Advertisers are willing to pay high fees to reach high-income consumers and those managers who make decisions to buy thousands of “ company cars” and computers. With such viewers，these programs don't need high ratings to stay on the air.

【1】Television sport programs on weekend afternoons __________.

A. result in more sport events

B. get more viewers to play sports

C. make more people interested in television

D. bring more money to the television networks

【2】Why would weekend afternoons become dead time without sport programs?

A. Because there would be few viewers.

B. Because the advertisers would be off work.

C. Because television programs would go slowly.

D. Because viewers would pay less for watching television.

【3】In many families, men make decisions on __________.

A. holiday trips

B. sports viewing

C. television shopping

D. expensive purchases

【4】The ratings are not important for golf and tennis programs because __________.

A. their advertisers are carmakers

B. their viewers are attracted by sports

C. their advertisers target at rich people

D. their viewers can afford expensive cars

【5】What is the passage mainly about?

A. Television ratings are determined by male viewers.

B. Rich viewers contribute most to television companies.

C. Sports are gaining importance in advertising on television.

D. Commercial advertisers are the major sponsors of sport events.
