A press report stating that Microsoft has restarted talks to buy Yahoo's search business for 20 billion U. S. dollars. "It has no basis in fact," the San Francisco Chronicle said on Monday.

The Times of London reported on Sunday that the deal under discussion would put former AOL CEO Jonathan Miller and Ross Levinsohn, a former president of Fox Interactive Media, in charge of Yahoo. The report also said executives (管理人員) at both companies had agreed to the broad terms of a deal.

In fact, there are no current talks between the two companies. The Chronicle quoted an executive at one of the firms who requested his name to be kept secret as saying. Furthermore, the 20-billion-dollar price mentioned in the Times of London article for Yahoo's search business appears questionable given that the market capitalization (資本總額) for all of Yahoo is 16 billion dollars, said The Chronicle.

Yahoo and Microsoft had had on-again, off-again talks over several months earlier this year about a 47. 5-billion-dollar takeover, and later a proposal focused only on Yahoo's search business. Discussions regarding both plans collapsed without an agreement.

Microsoft CEO Steve Ballmer has said repeatedly that he is no longer interested in buying all of Yahoo, but that he is open to some sort of partnership involving their respective search businesses.

Brad Williams, a Yahoo spokesman, said Sunday "We don't comment on rumors." Frank Shaw, a Microsoft spokesman, declined to comment.

Yahoo's shares have plummeted since Microsoft withdrew its 33-dollar-a-share acquisition offer earlier this year, leaving people to think that discussions would eventually be restarted. Yahoo's shares closed Friday at 11. 51 dollars, nearly one-third of the original offer.

1. From this passage, we can know that ______.

  A. Microsoft has given up buying all of Yahoo but its search business 

  B. Microsoft has already taken over the whole company of Yahoo

  C. the market capitalization for all of Yahoo is over $ 20 billion

  D. the market capitalization for all of Microsoft is only $ 6 billion

2. What is the author trying to convince readers of in the third paragraph?

  A. Yahoo and Microsoft are talking about takeover.

B. Microsoft is buying Yahoo’s search businesses for $ 20 billion.

C. Yahoo would like to sell its search businesses to another company.

D. There are no current talks between Yahoo and Microsoft.

3. What does the underlined word “plummet” in the passage most probably mean?

  A. develop rapidly      B. increase quickly      C. fall quickly     D. keep balanced

4. You can find this passage most probably in ______ .

  A. an entertainment website       B. an economical newspaper

Four in 10 Chinese complain about the great gap between large investments in education and its returns, a recent nationwide survey has showed.

The Horizon Research Consultancy Group polled 3,355 residents aged 16 to 60 in both urban and rural areas, including Beijing and Shanghai.

The survey found that only 16 percent of respondents believed their investments on education gave good returns.

Those with higher education voiced greater disappointment at the quality of education received, the survey showed.

People in the rural areas generally gave more positive feedback（反饋）on the quality of education than those from the cities, the survey found.

"Our education has been focusing on an examination-oriented system," Huo Qingwen, the deputy director of language education testing service center under the Beijing Foreign Studies University, told China Daily yesterday.

"The survey result doesn't surprise me, as I had heard complaints not only from the students, but also from the teachers who have been asked to focus more about the exam-passing rate," Huo said.

"The job market is still hungry for talented staff, but many graduates are not competent(勝任的) because the posts require more practical experience and creative ability of workers," Huo added.

Most university graduates prefer jobs in large cities, causing an imbalance in human resources between urban and rural areas, Hong said.

The graduates would get better job options if they chose to work at the grassroots (基礎(chǔ)的) level because of the government's preferential policies, including the waiving of tuition for those willing to work in the country's rural and western regions, he added.

About 580,000 graduates last year found county- or village-level jobs, and more than 550,000 got jobs in the central and western regions, Ministry of Education figures showed.

"Because many graduates focus only on jobs with high salaries and that are directly relevant to their specialties, they miss other good work opportunities," Kong Xiang, a Beijing graduate who works as an English teacher in a college located at a remote area in Yunnan province, said.

The recent survey showed that education costs form one-quarter of an urban family's income, while it forms one-third of a rural family's income.

46．According to the passage, most people think that _______

A. the investments in education gave them good returns.

B. the investments in education don’t bring them good results.

C. college students are satisfied with their the education received.

D. People in the cities are more satisfied with the quality of education than those in the rural areas.

47．Which of the following is NOT mentioned?

A. China’s education has been focusing on an examination-oriented system.

B. Both the teachers and students are asked to pay more attention to the exam-passing rate.

C. The job market now does not lack university graduates.

D. Most university graduates enjoy hunting jobs in large cities.

48. What would happen to the graduates if they chose to work at the grassroots level?

A. They would get higher salaries.

B. They would get lower salaries.

C. Their tuition would be free.

D. They would get better job choices.

49. How much does the education cost according to the survey?

A. One-third of a family's income.

B. one-quarter of a rural family's income.

C. 25% of an urban family's income.

D. Three in ten a rural family's income.

50. Which of the following can be the best title of this passage.

A. The gap between investments in education and its returns

B. Education and university graduates

C. China’s higher education

D. Education costs

ple — their clothes, ideas, or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree(可可樹)by South American. Indians. The Spanish introduced it to the rest of the world during the 1500’s. And although it was very expensive, it quickly became fashionable.

Brazil is now the world’s largest grower of coffee, and coffee is an important crop in Colombia and other South American countries. But it is native to Ethiopia, a country in Africa. It was first made into a drink by Arabs during the 1400’s.
