Directions：Read the following passage．Fill in the numbered blanks by using the information from the passage

　　Write NO MORE THAN THREE WORDS for each answer．

　　Since the earliest civilizations, people have controlled rivers to meet society's demands．Today, rivers are controlled for many reasons, primarily to maintain reliable water supplies for daily, agricultural and industrial needs, for power generation, for navigation(航行), and to prevent flooding．

　　River control is achieved by channelization, a term that covers a range of river engineering works, including widening, deepening, straightening and stabilization of banks, and by the construction of dams．

　　An important period of channelization took place in Europe during the l9'th century, when many large rivers were straightened and their beds deepened．One of the most dramatically changed was the Tisza River, a branch of the Danube that flows through Hungary．The controlling of the Tisza, designed to reduce flooding and make land for agriculture, included cutting off more than 100 meanders(河曲), shortening the river's length by nearly 400 kilometers．

　　One of the most common ways in which people control rivers is by damming them．The past 50 years or so has seen an increase in dam construction worldwide, and at the beginning of the 21st century, there were about 800, 000 dams globally, some towering more than 200 meters in height．

　　Despite their successes, many dams also cause significant environmental changes that prove harmful．Some particularly deep reservoirs(水库)can bring about earthquakes due to the stress on their bottom rocks caused by huge volumes of water．Downstream of a reservoir, the river is certainly influenced in many ways：water volume, speed and quality are all affected, leading to changes in the landscape and among plants and animals．

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.

    Tuesday was the eighth day of the 12 th month on the Chinese lunar calendar. I first became aware of the day as a traditional festival called laba, or the eighth day of the winter month – when I was working in a factory 30 years ago.

At lunch time，some elder co-workers opened their lunch boxes, and out came the sweet smell of well-cooked rice porridge mixed with beans，nuts and dates（枣）and they talked excitedly. Then, I wondered why there should be such an unnecessary excitement over the  laba festival. Growing up during the “cultural revolution” (1966－1976), when almost all traditional things were considered out-of-date，I had scarcely become aware of most of the traditional festivals.

I really started to value and celebrate these traditional festivals when I began to write about  Chinese culture. It is really encouraging that, despite the dramatic changes and modernization that our country has experienced over the past three decades, people have come to treasure many of our traditions more. Some people may have a complaint against the extreme commercialization（商业化）of these traditional festivals, but I believe the business promotions have at least worked to increase people’s awareness.

Most of the traditional Chinese festivals are celebrated with feasts. No wonder that on Tuesday a lot of people were buying rice，nuts，dry fruit, and beans from supermarkets and stores. A few thousand went to the Yonghegong Lama Temple to make prays for peace and happiness.  

Now that we have celebrated laba festival，we are now looking forward to the Lunar New Year, when we are supposed to have a lot more feasts. In fact, it is reported that almost all popular restaurants have been booked out for the Lunar New Year Eve dinner in major cities across the country.

    A．He takes them seriously all the time.

    B．He values them more than before.

3．The common ways to celebrate traditional Chinese festivals in the passage are to________.

       ① stop working in the factory               ② enjoy some special delicious food

       ③ have feasts with the family or friends     ④ pray for peace in temples

       ⑤ buy rice，nuts，fruits and beans         ⑥ write about Chinese culture

       A．①③⑤            B．②⑤⑥             C．①④⑥               D．②③④

4．From the last paragraph it can be inferred that now_________.

    B．people have become tired of laba festival

    C．people are living a better life than before
