The snow has paralysed(使癱瘓) transport in China during the country’s most important vacation period, the celebration of the Chinese New Year. Not only have transport delays hindered personal trips, but they have also slowed the delivery of fresh produce to markets. Consequently, in Zhengzhou, the capital city of the Henan province, tomato prices have doubled, and the cost of 47 other vegetables has increased by 36%, as reported by local media at the end of January.

     According to an inside PR source, “wholesalers in Beijing were quoted as saying that only about 20% of the usual fresh vegetable supplies were reaching the city.” As an Asian country with a diet based on fresh produce, the shortage of vegetables and the rise in prices is not only affecting fresh food producers, but also the final consumers.

     In terms of production, this is the worst snow disaster to hit China in the last 50 years, affecting a total of 9.4 million hectares of farmland in the country, according to a report published on 4 February 2008 by Feng Tao of Xinhua News, at the Chinese government website. Most of the crops devastated(毀壞)by the frost are located in the middle and lower reaches of the Yangtze River, the traditional natural border between North and South China.

Chen Xiwen, Director of the Office of the Central Leading Group on Rural Work, pointed out at the end of last week that “the blizzard disaster in the south has had a severe impact on winter crops, and the impact on fresh vegetables could be catastrophic in certain areas”, as stated in the Xinhua News report.

     The Chinese government has been quick to take extreme measures. The Chinese Ministry of Agriculture (MOA) has sent 13 teams of experts to 8 of the areas most seriously affected by the harsh weather. The aim of this initiative is to provide farmers with technical assistance to minimize their losses.

From this passage, we can know that the snow happened _____.

   A. During the Spring Festival

   B. In the coldest days of the winter

   C. In the North of China.

   D. It’s not mentioned here.

What’s the meaning of the underlined word in paragraph four?

   A. worst  B. snowstorm  C. cold weather  D. biggest

This passage mainly tells us _____ .

   A. The snow in the south of China caused many problems.

   B. The effect of the snow in the south of China on the fresh food

   C. The snow in the south of China slowed the delivery of fresh produce to markets.

   D. The Chinese government has taken extreme measures to help the suffered farmers.

The Chinese Ministry of Agriculture (MOA) has sent 13 teams of experts to 8 of the areas to _____ .

   A. help the farmers plant crops          B. give money to the farmers

   C. give directions to the farmers with their technic(技術;技巧).

   D. deliver crops for the farmers.

Kelly Reeves was getting ready for a trip when her phone slipped into a sink full of water. Panic moment! She quickly picked up the wet phone and tried to turn it on, but nothing worked. Her first reaction? She got dressed, drove to the nearest store, and bought a new model at full price.
A new study finds that fear of losing your phone is a common illness. About 66 percent of those surveyed suffer from nomophobia or “no mobile phone phobia”. Interestingly, more women worry about losing their phone than men.
Fortunately, there’s a solution.
The first step is to figure out if you have nomophobia. Checking your phone too often is one thing, but the true sign of a problem is that you can’t conduct business or go about your routine when the fear becomes so severe.
Do you go to unusual lengths to make sure you have your phone? That’s another sign of a problem. If you find you check your phone plenty of times per hour, or a total of an hour per day, there may be a problem.
Some of the treatments are similar to those for treating anxiety attacks: Leaving the phone behind and not checking e-mail or text messages, and then learning to tolerate the after anxiety. Even if this leads to a high level of worry and stress, the solution is to push through the fear and learn to deal with not having your phone.
Of course, there are also technological alternatives. Luis Levy, a co-founder at Novy PR, says he uses an application called Cerberus that can automatically track the location of his phone. To find it, he can just go to a Web site and see the phone’s location.
He also insures his phone through a service called Asurion. The company’s description of its product reads like a prescription for anxiety: “60 million phones are lost, stolen or damaged each year. You’ll have complete peace of mind knowing that your phone is protected and you can quickly reconnect with family, friends and work, as soon as the very next day!”
【小題1】Why does the author mention Kelly’s experience in the first paragraph?

A.To inform us that mobile phones are useful.
B.To introduce the topic for discussion.
C.To tell us we should get phones ready for a trip.
D.To warn us that we should be careful.
【小題2】The underlined word “nomophobia” in Paragraph 2 means ________.
A.Fear of losing mobile phones.
B.Habits of using mobile phones
C.Independence of mobile phones.
D.Eagerness for new mobile phones.
【小題3】Which of the following is a way to treat nomophobia?
A.Learning more about modern technology.
B.Avoiding using phone for some time
C.Not using a mobile phone in one’s daily work.
D.Protecting one’s phone against any damage.
【小題4】Why can the service called Asurion help to treat nomophobia?
A.It will give you a new phone through insurance.
B.It lets you know other people also lose their phones.
C.It gives you a prescription to treat nomophobia.
D.It enables you to reconnect with your acquaintance.
【小題5】What is the passage mainly about?
A.New mobile phone technology.
B.Attitude toward mobile phone.
C.Solutions to nomophobia
D.Disadvantages of mobile phone

.
What do you see from a handful of seeds? Some see green plants, some see blooming flowers, or just seeds. But one group of Shanghai students saw an opportu­nity to make money.
Eight students from No 2 Secondary School Attached to East China Normal Uni­versity started a virtual company selling different seeds and seed products. They successfully sold 28 pictures pasted with different seeds at a campus auction a week a­go. The company, which has recruited around 20 student staff members, has earned over 2000 yuan in the past three months.
"We donated part of the money to a poor school in the countryside of Anhui Province. It's great to realize our ideal of ‘spreading love and culture with seeds’ after many tests and lots of hard work," said Senior 2 Shi Chen, CEO of the compa­ny.
Just like any other company, Shi's didn't develop smoothly. Shi and her young colleagues used to sell fresh flowers and old books, and later found seeds might be something that their company could engage in. They bought seeds of various plants and flowers at low prices from a local farm and sold them in schools or on streets. The creative students also made accessories and pictures with different seeds.
With little business knowledge, the students had to learn new skills as the lead­ers of different departments, such as public relations (PR), sales and marketing. They persuaded a joint Sino-French company near their school to give them training in business management. They also asked some local businessmen to act as their consul­tants.
"They helped us overcome our shyness. We also learned quite a lot of business theory. I found communication skills and teamwork are very important for my job," said Senior 1 Qian Yifei.
The 16-year-old was elected as PR manager thanks to her talent for speaking. She is also in charge of after sales service, dealing with complaints and providing suggestions.
As the head of the company, CEO Shi has a lot more to think about. First of all, she has to learn how to make her colleagues work efficiently as the company only opens at weekends due to all their studies. So she established a system to evaluate every one's performance, in terms of punctuality, efficiency, profits knowledge and so on.
"It makes the company more formal," she said.
59. What is the purpose of opening the company?
A. To earn money for their education fees.
B. To spread love and culture with seeds.
C. To see whether they can open a company.
D. To collect money to open a Hope School.
60. At a campus auction a week ago, they ________ .
A. sold 28 green plants with different flowers
B. sold 28 seeds pasted with different pictures
C. sold 28 pictures pasted with different seeds
D. sold 28 flowers pasted with different pictures
61. According to Qian Yifei, what matters most in dealing with public relations?
A. Communication skills and teamwork.
B. Creative and critical thinking.
C. Educational background.
D. Business theories.
62. What does the word "it" (in the last paragraph) refer to?
A. Selling seeds.
B. To have a person as CEO.
C. Every colleague’s performance.
D. To make her colleagues work efficiently.
63. What can we learn from the passage?
A. The company is owned by 8 students.
B. The company is over-night successful.
C. The company gets a lot of help from others.
D. The company sells old books and fresh flowers.

認真閱讀下面短文,并根據所讀內容在文章后圖表中的空格內填入最恰當的詞。

 注意:每空一詞。

Ten is not just a number. For Hong Kong, it means change. That change began 10 years ago on July 1, 1997, when Hong Kong was returned to the mainland. A year later, putonghua became a major subject in middle schools there. Street chatter now is trilingual: Cantonese, English and putonghua.

But language is just one of the many changes. Over the past 10 years, the flow of people has left its mark, especially on the young people.

The first sign is in the job market. Before 2006, about 10,000 young professionals from the mainland found jobs in Hong kong. At the same time, around 240,000 Hong Kong residents had worked or were working on the mainland. More than 60 percent of them were aged 23 to 25, according to official statistics.

Geng Chun, 26, a native of northern China, managed to start his own IT business after completing his university degree in Hong Kong three years ago.

“I like Hong Kong,” Geng said. “Hong Kong needs us. We’re young, well-educated and energetic.”

Education is the next thing to change. After the return, more people from both the mainland and Hong Kong began crossing the border to get an education.

According to China’s Ministry of Education, in 2006, 914 Hong Kong students were admitted to mainland universities. In all, 7060 studied in the mainland that year. Before that time, Hong Kong students were rarely seen in mainland schools.

There was a growth on the other side as well. In the early 1990s, about 100 mainland students went to Hong Kong every year to study. Last year, 1300 studied in Hong Kong universities.

Besides social and cultural changes in Hong Kong, business exchanges between the mainland and Hong Kong have greatly increased.

 According to a Xinhua report, by the end of 2006, the mainland’s total investment in Hong Kong had reached $40 billion since 1997, which makes up 57 percent of all investments to places outside the mainland.

“We have many clients from the mainland, and actually, they are becoming our biggest group of clients,” said Ho, a manager for a Hong Kong PR company. “The mainland has provided our company with more business opportunities, which are vital for our development.”

Ten Years Reshapes Hong Kong

Market

(8)_______________ exchange

a.       From 1997 to 2006, the mainland altogether (9)_______________ $4 billion in Hong Kong.

b.       The mainland has provided more business (10) ________________ for Hong Kong companies.
