题目内容

Half of the world’s population is affected by Asian monsoons (季风), but monsoons are difficult to predict. American researchers have put together a 700-year record of the rainy seasons, which is expected to provide guidance for experts making weather predictions.

Every year, moist (潮湿的) air masses,known as monsoon,produce large amounts of rainfall in India, East Asia, Northern Australia and East Africa. All this wet air is pulled in by a high pressure area over the Indian Ocean and a low pressure area to the south.

According to Edward Cook, a weather expert at Columbia University in New York, the complex nature of the climate systems across Asia makes monsoons hard to predict. In addition, climate records for the area are too recent and not detailed enough to be of much use. Therefore, he and a team of researchers spent more than fifteen years traveling across Asia, looking for trees old enough to provide long-term records. They measured the rings(年轮), or circles, inside thousands of ancient trees in more than 300 places.

Rainfall has a direct link to the growth and width of rings on some kinds of trees. The researchers developed a document they are calling a Monsoon Asia Drought Atlas. It shows the effect of monsoons over seven centuries, beginning in the 1300s.

Professor Cook says the tree-ring records show periods of wet and dry weather. “If the monsoon basically fails or is a very weak one, the trees affected by monsoons at that location might put on a very narrow ring. But if the monsoon is very strong, the trees affected by that monsoon might put on a wide ring for that year. So, the wide and narrow ring widths of the chronology(大事年表) that we developed in Asia provide us with a measure of monsoon variability.” With all this information, researchers say they can begin to improve computer climate models for predicting the behavior of monsoons.

“There has been widespread famine and starvation and human dying in the past in large droughts. And on the other hand, if the monsoon is particularly heavy, it can cause extensive flooding.” said Eugene Wahl, a scientist with America’s National Oceanic and Atmospheric Administration. “So, to get a sense of what the regional moisture patterns have been, dryness and wetness over such a long period of time in great detail, I would call it a kind of victory for climate science.”

Nothing says love like a dozen long – stemmed roses on Valentine’s Day. More than a million roses will be sold during this festival for lovers, the biggest day of the year for the nation’s rose industry. It’s going to remain the most popular flower because love never goes out of style.

Yes, a rose is a rose is a rose. But selling them is no longer a beautiful experience for traditional flower shops. Supermarkets now offer convenience to the busy and discount rose shops help those hopelessly in love save money. Roses only is a good example of a discount rose retailer that was transformed from a traditional shop to answer the challenge in the’ 90s.

Inside this store on Sixth Avenue near 40 th Street, contemporary white furniture and wall – to – wall mirrors give it an expensive look. Customers move about freely among the counters, looking eagerly at the roses in more than 50 colors from shelf to shelf. Some customers say it’s the high quality of the roses that attracts them there. “I spent $ 20 but the flowers looked like I paid 60 or 70 dollars,” says one customer.

Studies show more people are buying roses in ones, two and threes these days. In fact, more than half of all roses are sold in bunches of fewer than a dozen. But Roses Only's low prices encourage people to spend. Even on Valentine's Day, when the price of a dozen roses and delivery can soar as high as $150, 12 of Roses Only's most expensive flowers sell for just $35. The company's key to success is to hold prices down by controlling every link in the rose chain. It grows its own roses in the sunshine of the Andes Mountains. In addition, the company also sells other items such as ballons and stuffed animals.    

       While discount rose retailers are witnessing their business bloom, U.S. rose growers aren’t able to compete with the fierce foreign competition. More than 57% of roses sold in the USA are grown in other countries. The biggest foreign producers are Colombia and Ecuador, which accounted for almost 90% of the total imported last year. The trend has hurt domestic rose growers such as Johnson Flowers of California, considered to be this country's leading producer.

Now, instead of fighting overseas rivals, the Johnsons are trying to work with them. "We have a few big fighting overseas rivals, the Johnsons are trying to work with them. “We may also widen our business to include the service area and be a representative for overseas flower producers.”

       As a result of severe competition, those in the rose business long for the good old days, whereas ordinary people benefit from the low price.

60.What is the central theme of this text?

A.The US rose business is going from bad to worse in spite of the efforts made.

B.The rose will remain the most popular flower as love never goes out of date.

C.The rose business is trying to meet the challenges in the market to succeed.

D.The rose industry plays an important role in American economy.

61.How does Roses Only obtain success in the discount rose retailing field?

       A.By setting up more chain stores across the country.

B.By selling roses in supermarkets.

C.By selling high quality roses at a low price.

D.By selling roses by the dozen.

Over three million people will do their Christmas shopping entirely online this year without once visiting an actual shop, a poll (民意调查) has found. Overcrowding and long queues in shops are forcing people away from the high street as the hassle (烦扰) of Christmas shopping becomes too much.
The number of people turning their backs on the high street is almost one million higher than it was last year, according to the poll by YouGov. Last Christmas 2.4 million shoppers did not do any of their shopping in actual shops. The figure this year is predicted to be around 3.4 million, equal to around 7 percent of the adult population.
Over a third of people said that the main turn-off about shopping on the high street is 0ver-crow-ding. Meanwhile almost a quarter said that long queues at the cheek-out are the worst thing about it.
Of the 2.065 people pored, even those who are stir taking to the shops plan to spend less time in them this Christmas. Around 31 percent of shoppers who plan to spend at least some time on the high street will spend less than half of their shopping time in actual shops, using the rest of the time to shop remotely via the internet. This compares to 28 percent of people last year. Meanwhile the proportion of people spending over half of their shopping time in high street shops has dropped from 41 percent last year to 39 percent this year. Just 2 percent of people said that they are looking forward to dealing wi.th store staff this festival season.
Guy Boxall, senior product marketing manager at Casio Business Solutions Division, which commissioned the research from YouGov, said that despite the fall in people visiting the high street,humans are "social creatures" who actually like spending time together.
"Although the high street is facing a big challenge Christmas, retailers (零售商) should see this research as a challenge to improve the in-store shopping experience, rather than the nail in the coffin. We are social creatures, and the desire to spend time with each other, particularly at Christmas, is never going to go away," said Mr. Boxall.

第二部分:阅读理解(第一节20小题,第二节5小题;每小题2分,满分50分)

第一节:阅读下列短文, 从每题所给的四个选项 (A、B、C和D) 中, 选出最佳选项。

Being interested in a theme park since the time that I was a child, I have learned a thing or two over the years about packing for a day of fun. A trip to a theme park is always a adventure, but if you’re not prepared, your day of fun could easily turn into a tiny little nightmare(噩梦). It is important to pack long sleeved(带袖的) shirts or jackets for all members of your family. I is also a good idea to pack an extra pair of socks for each member of the family, especially the children, as those wonderful water rides can be fun, but wet socks that won’t dry aren’t so much fun.

You don’t want to pack too much food, as you will probably want to experience at least some of the food offered at the theme park of your choice(that’s half of the fun), but it’s always a good idea to bring some energy increasing snacks, such as fruit,trail mix,etc. This can mean the difference between spending a lot of money on snacks or a little money on one or two good meals.

Theme parks,while fun and exciting, can wear a person out,especially a child, so it’s important to keep hydrated(含水的). I would suggest packing one bottle of water per person, and possibly a couple of cans of soda or bottles of juice as well.

It’s a good idea to have at least two cell phones or even a set of “walkie-talkies” in the event that your family gets,separated in the park. It’s a good idea to give one of these things to the children and one to the parents and make sure that each of them knows how to use it. This could be the difference between trouble and a happy ending,

1.You should get well prepared before going to a theme park__________.

  A. because the trip always costs much money

B.because there are always too many people in a theme park.

C. so as not to suffer from bad dreams when going back

D.so as to cut down your trip expenses and have more fun

2.From the passage, we can know_______________.

  A.the author was fond of visiting theme parks when he was a child

B.wearing wet socks in a theme park will bring children much fun

C.it is terrible to have a taste of the food offered in a theme park.

D. we’d better bring enough food, clothing and water when going to a theme park

3.What does th underlined part”walkie-talkies” in the last paragraph probably refer to?

  A. A kind of transportation tool           B.A kind of musical instrument

C.A kind of CDplayer                  D.A kind of phone

4.How many types of things does the author advise us to pack for day trips to a theme park?

  A Three         B.Five      C.Six      D. Eight
