Have you ever imagined that you could be cloned(克隆) like Dolly, the sheep, in the not too distant future?
The news that a human embryo(胚胎) has been 16 cloned for the first time has caused mixed reactions(反应).
The 17 was carried out by scientists from the Advanced Cell Technology Inc(ACT), in Massachusetts, US. The group 18 the news on November 25.
This is 19 human being. A clone is alive, it walks, it breathes, said Jamie Grifo, a(n) 20 on the study of cloning at New York University School of Medicine.
“This is a set of cells in a lab that will be used to 21 someone’s life.”
Such research could lead to treatment for 22 such as heart disease, AIDS and even cancer, 23 scientists.
Despite high hopes from other scientists, the news raised concerns immediately from religious and political leaders. Several 24 in the US do not allow human cloning. President George W. Bush also made it clear that he is 25 any type of human cloning. However, the scientists at ACT said they have no interest at present in 26 an early embryo into 27 .
Animal have been cloned repeatedly since Dolly, the sheep 28 in 1997. And there were no real technical 29 to stand in the way of scientists making a cloned human embryo.
This time the research group used traditional cloning technology with a human 30 . 31 it was given DNA from an adult cell, the egg began to 32 . 33 it was stopped from becoming a baby-at a stage in which it was 34 a ball of cells. The 35 technology has been used to clone sheep , cattle and monkeys.

Beijing ?（13, July） China sent up a new data relays atellite （数据中继卫星）, Tianlian I -02, on Monday at the Xichang Satellite Launch Centre in South-western Sichuan province．The new satellite will promote the country"s satellite communication network for space docking （对接）．
The satellite was launched on a Long-March-SC carrier rocket at 11:41 p．m．, sources at the centre told Xinhua News Agency．The satellite separated from the rocket 26 minutes after its launch and was then successfully delivered into a geostationary transfer orbit （地球同步转移轨道）.
Developed by the China Academy of Space Technology under the China Aerospace Science and Technology Corporation, the satellite is the country"s second data relay satellite．The first, Tianlian I -01, was launched on April 25．2008．
The two satellites will form a network to improve communications between China"s spacecraft and bases on Earth, according to the centre．They will also be used to help the nation"s first space docking, scheduled for the second half of this year．
As planned, China will launch space module Tiangong-I （天宫1号）, which was designed as a platform that will dock with an unmanned spaceship, Shenzhou, for the county"s first space-docking mission this year．
Two more Shenzhou spaceships will dock with Tiangong-I next year, and one will be manned by two or three astronauts, according to China Manned Space Engineering Office, which was the main user of the Tianlian I series data relay satellites．
"The new satellite can cover a greater area to track and command the country"s space vehicles m low-Earth orbits, such as manned spacecraft and remote sensing satellites, from a higher position m outer space．Only three satellites of this kind are needed to form a global communication network, and China has two now．" Pang Zhihao, a researcher and deputy editor-in-chief of Space International, said．
The satellite could also equip astronauts with real-time communications, which will benefit the county s future manned space flights, he said．
小题1:What is the main purpose to send up Tianlian I -02 ?| A．To test the function of a Long-March-SC carrier rocket． | | B．To carry some astronauts into space to do some research． | | C．To send more information and clearer pictures to mobile phones on the earth． | | D．To promote the country"s satellite communication network for space docking" |
小题2:From the passage we know .| A．one more such satellite is needed to form a global communication network | | B．the satellite was developed by China Manned Space Engineering Office | | C．it was less than three years since China launched its first date relay satellite of this kind | | D．the satellite could help track and command space vehicles in orbits because it"s lower in position |
小题3:Which of the following is TRUE according to the news report?| A．Shenzhou Ⅷ is a manned spaceship． | | B．Tiangong- I will dock with three Shenzhou spaceships next year． | | C．the satellite is of great importance to China"s space exploration． | | D．china’s first ^a06 docking will be done in the second half of next year. |

The Friday after the American holiday of Thanksgiving is called Black Friday. It’s said that it’s the day that store ledgers(分类账)move into the black and companies become profitable（有利可图的，有益的）. On that day, retailers（零售商）slash prices to get consumers to buy. It is also a time when many Americans start their Christmas shopping. VOA’s Elizabeth Lee tells us how the economy may affect consumers on that bargain day.
“It’s just the deals, the sales and everything you can get for a lesser（较少的，较小的）price,” said Sandy Thomas, a shopper. But it’s a nightmare（噩梦）for others. “I think it’s crazy. I’ve done all of my shopping throughout the week so I don’t have to go out on Friday,” she said. It’s called Black Friday, the start of the traditional Christmas shopping season in the United States. Every year it’s the day after the Thanksgiving holiday. Stores open before sunrise and there are deep discounts everywhere you look.
While the lead up to Christmas is known as the season of giving, Black Friday can get ugly.
Last year a crowd of bargain-hunters killed a Wal-mart（沃尔玛公司）worker in a New York suburb. This year, many stores are increasing security while they slash prices. “This is a huge time for the retail stores,” said Fred Joutz from George Washington University. “This is when they begin making their profits for the year.”
Economics professor Fred Joutz says how Americans spend the weekend after Thanksgiving is a good indication of how consumers feel about the future.
With the unemployment rate above 10 percent, Joutz says Americans are saving more and spending less. “Credit is still strictly controlled whether through credit cards or through borrowing from banks,” he said. Some retailers are attracting consumers by opening on Thanksgiving Day, when shops are traditionally closed. Other stores open their doors anywhere from midnight to four in the morning.
And shoppers will be lining up in front of the doors in order to be one of the first ones to walk through and get a big discount. Electronics like flat screen TVs are usually the first items to go. Sandy Thomas says it’s an annual family tradition and well worth it. “I just save maybe half of what I would have spent on a regular, you know, shopping trip,” she said.
Economists say U.S. consumers will spend money this Black Friday, but they will spend it more carefully.
小题1: The underlined word “slash” in the first paragraph probably means _________.| A．reduce | B．raise | C．increase | D．change |
小题2:The sentence “This day should be a shopper’s dream.” should be placed between ________.| A．paragraph two and paragraph three | B．paragraph one and paragraph two | | C．paragraph three and paragraph four | D．paragraph five and paragraph six |
小题3:Why are many stores increasing security according to the passage?| A．Because there are too many people saving more and spending less. | | B．Because it’s a time when they begin making their profits for the year. | | C．Because last year a crowd of bargain-hunters caused an accident. | | D．Because many stores open their doors from midnight to four a.m. |
小题4:What can we learn from the passage?| A．Christmas shopping is traditional time and this year it is no exception. | | B．Electronics like flat screen TVs are usually least discounted. | | C．The economy only affects consumers on that bargain day. | | D．Thanksgiving is a good indication of how consumers feel about the future. |

The dyed bun scandal (染色馒头丑闻) deals another blow to shoppers" confidence in buying food products, as well as the reputation of local sellers. Li Zhen reports on shoppers’ reactions in Shanghai.
An investigation by the municipal government revealed that Shanghai Shenglu Food Company produced more than 3,000 steamed buns daily. These were then sold across the city, including large supermarkets such as Hualian, Lianhua and Dia.
Fewer steamed buns were for sale at this Lianhua Supermarket. More than 32,000 buns were taken off store shelves when the scandal emerged.
Mr. Wang, Sales Manager of Lianhua Supermarket, said, “We removed the dyed steamed buns produced by Shenglu as soon as we learned of the incident.

However, most customers we met remained concerned about food safety. Steamed buns are a regular breakfast food for Ms. Gao. She used to buy them mostly from supermarkets because she felt it was in a clean and safe environment.
But now, she has second thoughts about buying the popular snack.
