71 Many Americans make a promise that they will find a new or better job in the new year. And many businesses decide to fill empty positions this time of year. There are many ways to find a job. It can be as easy as walking into a neighborhood store to look at its announcement board. Local stores often have areas where people can put small signs telling what kind of service they need or can provide. 72 Or, job searchers can look in the newspaper. Local newspapers have employment announcements placed by companies seeking workers. 73 Now, people in 450 cities around the world are using the Web to meet people or find a job. It is estimated that two million new job listings are offered each month. 74 It is because almost every one of them has the Career Exploration center for people to get help in finding a job.

Of course, looking for a job requires knowing what kind of work you want to do. For example, there is a book called What Color is Your Parachhute? by Richard Bolles. This book has been helping people choose a career since it was first published in 1970. 75 They can help people find jobs by first helping them understand their strengths, goals and interests. And then they provide them with methods and resources to help people find the right job.

B. Such services include caring for children or cleaning houses.

D. Another popular tool for finding jobs is the Internet.

The number of speakers of English in Shakespeare’s time is estimated (估计) to have been about five million. Today it is estimated that some 260 million people speak it as a native language, mainly in the United States, Canada, Great Britain, Ireland, South Africa, Australia and New Zealand. In addition to the standard varieties of English found in these areas, there are a great many regional and social varieties of the language as well as various levels of usage that are employed both in its spoken and written forms.
In fact, it is impossible to estimate the number of people in the world who have acquired an adequate (足够的) working knowledge of English in addition to their own languages. The purpose for English learning and the situations in which such learning takes place are so varied that it is difficult to explain and still more difficult to judge what forms an adequate working knowledge for each situation.
The main reason for the widespread demand for English is its present-day importance as a world language. Besides serving the indefinite needs of its native speakers, English is a language in which some of important works in science, technology, and other fields are being produced, and not always by native speakers. It is widely used for such purposes as meteorological and airport communications, international conferences, and the spread of information over the radio and television networks of many nations. It is a language of wider communication for a number of developing countries, especially former British colonies. Many of these countries have multilingual populations and need a language for internal communication in such matters as government, commerce, industry, law and education as well as for international communication and for entrance to the scientific and technological developments in the West.

XUE Bai, a 21-year-old university student, hopes to volunteer for Beijing's 2008 Olympics. "I want to do something for the Olympics. It is also a kind of learning for me," said the fourth-year student at Beijing Foreign Studies University. Now it is time for Xue to act on her plan. The Beijing Organizing Committee for the Games of the 2008 Olympiad will start to recruit(招募)volunteers on August 28.

The Olympics will need around 70,000 volunteers and the Paralympic Games(残疾人奥运会) will need another 30,000. University students like Xue will make up the majority of the volunteers. But the Olympics also need other volunteers - ordinary citizens and foreigners, for example. Students in Beijing should apply through their universities. Other volunteers may apply online or submit a written application. The online application system and a hotline will be open next Monday. For applicants outside Beijing, the application process begins in December. There is plenty of work for volunteers to do. For example, there will be chances to help publicize the games over the next two years. During the games themselves, volunteers will clean, serve food, marshal(礼仪引导)or offer language help.

The Sydney Olympics in 2000 was the first that placed special emphasis on the role of volunteers. It used more than 45,000 volunteers in different roles. In the 2004 Athens Olympics, around 45,000 volunteers were used. More than 70,000 volunteers will be needed for the Olympic games and Paralympic Games in 2012, the London Olympic Organizing Committee has said.

Consumer electronics once again topped the list of the most wanted gifts this holiday season.

“Seventy-six percent of consumers who plan to buy holiday gifts say that they will spend money or buy at least one technology product; definitely a solid vote of confidence for technology.”

Steve Koenig is with the Consumer Electronics Association. He says the group’s latest research also shows that Americans this year are spending more on technology products. “Here in 2012, $252 on average——the technology spend for consumers this year.”

From tablet computers to smart phones, American shoppers have been lining up to get the newest and coolest electronic devices on the market. There are more choices today than ever before. "It's kind of hard to make a decision."

Tablet computers are one of the best-selling products this year. Brian Tong is Senior Editor of CNET.com. The website reports on tech news and examines the latest electronic products. He says the Apple iPad Mini is one of the most popular tablets. Its starting price is $329. One of Apple’s biggest competitors is the Google Nexus 7. It starts at $199.

“Its hardware is more powerful than what’s in the iPad Mini, but also it offers you a lot of things like maps that work better than Apple’s maps.

But Brian Tong says there is one reason why people may like the iPad Mini more than the Nexus 7. “If you just want to read books and surf the Internet, you don’t really need to get an iPad Mini, but if you want the largest robust group of apps (应用软件) that’s where the iPad and Apple’s ecosystem shines the most.”

Elman Chacon is with the electronics store Best Buy. He says another hot product this season is smart cameras. They connect to the Internet through WiFi. This makes it easy for users to email or upload photographs directly from the camera.

“You can literally take a picture and upload it into your Facebook in a matter of seconds. These things are pretty cool because they do a lot of things.”

Streaming media boxes also connect to the Internet. People are able to watch web content such as movies and YouTube videos on their televisions. Another popular item is wireless speaker systems. The newest ones work with any device that has Bluetooth technology, including smart phones, laptops and tablets.

B．Consumers are spending $252 more on technology products than last year.

C．Consumers should spend $252 on their technology products.

D．It is estimated that $252 on average might be spent on electronics by consumers in 2012.

2.According to Brian Tong, why may people prefer the iPad Mini to the Google Nexus 7?

A．Because it is cheaper.

With only about 1,000 pandas left in the world, China is desperately trying to clone the animal and save these in a dangerous situation. That's a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called "Noah's Ark".

Noah's Ark is aimed at collecting eggs, embryos(???), semen and DNA of these animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M's College of Veterinary, Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.

It is estimated that as many as 2, 000 species of mammals, birds and reptiles will probably become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.

This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.

The entire procedure could take from three to five years to complete.

"The nuclear transfer of one species to another is not easy, but the lack of available panda eggs could be a major problem," Kraemer believes. "They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it's difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort," adds Kraemer, who is one of the leaders of the Project at Texas A&M, the first-ever attempt at cloning a dog.

"They are trying to do something that's never been done, and this is very similar to our work in Noah's Ark. We're both trying to save animals that face extinction. I certainly appreciate their effort and there's a lot we can learn from what they are attempting to do. The cooperation between us is very much needed."

67. The final aim of "Noah's Ark" project is to___________. .

A. make efforts to clone the endangered pandas

B. save endangered animals from dying out

C. collect DNA of endangered animals to study

D. transfer the nuclear of one animal to another

68. According to Professor Kraemer, ___________.

A. the long time lasting cloning research could be successful.

B. the eggs transfers immediately result in having a baby.

C. the lack of nuclear transfer could be a major problem to have new pandas.

D. if species should die out, basic building blocks would heal them.

69. The best title for the passage may be______________.

A. China's Success in Pandas Cloning

B. Helping Ways to Avoid Extinction

C. Exploring the Possibility to Clone Pandas

D. The Practice in Noah's Ark

70. From the passage we know that______________.

A. Kraemer and his team have succeeded in cloning a panda

B. scientists try to implant a panda's egg into a rabbit

C. Kraemer will work with Chinese scientists in clone researches

D. about two thousand species are to die out in a century
