Surgeons in Spain have successfully carried out the world’s first organ transplant using new stem cell technology. Some people are calling it the greatest medical breakthrough so far this century.
But what are stem cells? As we know, most cells in our bodies are designed to serve specific purposes – for example, a liver cell develops to work in the liver and cannot become a heart cell. But stem cells are different. They are very young, and in the laboratory scientists can grow them into different types of cell.
Claudia Castillo needed a new windpipe after getting a serious disease. Scientists from the University of Bristol in the UK took a donor windpipe, or trachea, from someone who had recently died. They used strong chemicals to remove the donor’s cells, leaving a tissue scaffold(组织支架). This was refilled with cells from Ms Castillo’s windpipe, and stem cells from her bone. After four days the cells had grown sufficiently for the windpipe to be transplanted into Ms Castillo.
Currently, transplant patients have to take drugs for the rest of their lives to prevent their bodies rejecting the new organs. These drugs can have bad side-effects, and do not always prevent rejection. But by using Ms Castillo’s own cells, doctors were able to trick her body into thinking the new windpipe was her own organ. Five months on, Claudia Castillo is in perfect health.
This ground-breaking procedure could be used in other transplant operations in the future. Scientists also believe stem cells might be used to treat Parkinson's disease, Alzheimer's disease, heart disease, stroke, arthritis, diabetes, burns and so on.
However, stem cell research is extremely controversial. The most effective stem cells do not come from adults but from embryos created in laboratories and which are just a few days old. Many people have religious or ethical objections to growing embryos, even if they can be used to cure diseases.This transplant is considered the greatest medical breakthrough because _________.
| A．this is the first organ transplant in the whole world |
| B．the patient is in perfect health after the operation |
| C．it is the first success with new stem cell technology |
| D．the stem cells are from an embryo developed in a lab |

| A．they are grown in the lab only |
| B．they can grow into different types of cell |
| C．they are designed for a specific purpose |
| D．they can work in the liver not in the heart |
What is the main idea of the third paragraph?
| A．How Claudia survived in the operation |
| B．How to remove the cells from the donor’s organ |
| C．Why stem cells are needed in the transplant |
| D．How the windpipe is transplanted |
Which of the following is TRUE according to the passage?
| A．Human bodies always reject transplanted organs even with their own cells |
| B．The donor’s cells had to be removed because they were unhealthy |
| C．The transplanted organ was refilled with the stem cells only |
| D．Claudia will not have to take drugs to prevent rejection. |
Which word can best describe the scientists’ attitude towards the stem cell technology?
| A．controversial | B．confident |
| C．conservative (保守的) | D．critical |

The first MP4 player was born years ago. Soon many music fans were wondering how fantastic it is! If you have been into technology enough, perhaps you may have a knowledge of the MP4. If not, you do need to know something before buying one, even if you are familiar with MP3. MP3 is the CD-like disc with greater capacity. How about MP4? This small digital product will really enrich the joy from listening to music. You can even feel the “touch” of music to your soul!
Now, some similar digital products advertised as “MP4 player” are simply MP3 players, which do not play video and MPEG format and also lack other particular functions. These products confuse some buyers, as they may think the “MP4” players simply mean they can do more than MP3.
What is MP4?
It is a multimedia container. It is not only used to store digital audio and digital video streams, especially those of MPEG, but can also be used to store other data such as subtitles and pictures. As a most modern container format, it allows streaming over the Internet.
With the help of a piece of MP4 video equipment, you can change various programs such as MPEG to MP4, ASX to MP4, AVI to MP4 and so on, which can be done very quickly and easily without any effect on the sound quality. By installing DVD-MP4 software, you can transfer particular music from a DVD to an MP4 video file. It really excites your listening music experience.
Then, there is MP4 advanced and you can set your own collection of all the programs—TV shows, games, and music. You can even see movies which are still running in cinema. What else digital product could you possibly ask for? It is suggested here that you should ______ before buying an MP4 player.
| A．first be a music fan | B．have a knowledge of MP4 |
| C．get familiar with MP3 | D．buy a CD-like disc |
From the passage, we can see that MP4 is ______ MP3.
| A．much bigger than | B．just as advanced as |
| C．not so particular as | D．more functional than |
Which function of MP4 is NOT directly mentioned in this passage?
Ａ．Storing digital audio and video streams.
Ｂ．Recording some movies in cinema.
Ｃ．Playing TV shows, games and movies.
Ｄ．Transferring particular music from a DVD.From the last sentence, it’s clear that the writer tries to tell us it is ______.
| A．reasonable to buy other digital products |
| B．impossible to buy something else |
| C．a very wise choice to buy an MP4 |
| D．an exciting experience to buy an MP3 |

China’s economic growth “hard to predict”
The worsening global economic situation makes it difficult for China to predict its growth for next year, a senior official said on Friday.
“How fast China’s economy will grow next year is uncertain,” Liu He, deputy director of the Office of the Central Leading Group on Finance and Economy Work, told China Daily.
“To a large extent, the rate will be decided by the external(外部) situation,” Liu said during a discussion with Swedish Prime Minister Fredrik Reinfeldt and other economists in Beijing.
“This year, GDP is estimated to grow at 9.4 or 9.5 percent, down from 10.6 percent last year,” he said. “However, the impact of the current financial turbulence on our economy is much less than on the rest of the world.”
Nicholas Stern, a former UK government advisor, also told China Daily it will take at least one or two years for the world to recover from the recession, which is now spreading from the US and the UK to the rest of the world.
“We don’t know how long the recession will last, but it is unlikely to be short,” he said.
Liu said China can use the downturn(衰退) as an opportunity to restructure its economy, which has relied heavily on government investment, foreign trade and low-cost technology over the past years.
“When the economy is experiencing fast growth, companies are unwilling to upgrade their technologies,” Liu said.
“The slowdown gives such firms the opportunity to enhance(提高) their competitive edge through better technologies.”
(From China Daily 2009-01-11)How many people are mentioned in this passage?
| A．Only 2. | B．No more than 3. | C．Not more than 4. | D．At least 5. |
It can be inferred from Liu’s words that the impact of the current financial turbulence on China’s economy is ______.
| A．more | B．less | C．the most | D．the least |
The underlines word “extent” probably means ______.
| A．sense | B．degree | C．size | D．depth |
According to the passage, the reason why Liu said this downturn is an opportunity for China to restructure its economy is that ______.
| A．China’s economy will not depend on government investment in the future |
| B．Foreign trade will grow in the future |
| C．The downturn will force China’s companies to upgrade their technologies |
| D．Low-cost technologies will not exist in China |

Ａ
Researchers who helped discover a new species of Mexican butterfly are offering to sell the naming rights to raise money to fund more research. Co-discoverer Andrew Warren is hoping to raise at least $50,000 by auctioning(拍卖) off the rights to name the 4-inch “owl eye” butterfly, which lives in Sonora, a Mexican state bordering Arizona.
“That would support at least two years of research for our team down in Mexico,” Warren said. “Money goes a long way down here in Mexico.”
According to the scientific tradition, discoverers of a new species have the say in naming it. In recent years, some discoverers have auctioned off their naming rights to raise money.
Warren said the amount being sought for the butterfly is not out of the question, noting that naming rights for a new monkey species brought in $650,000 two years ago. A group of 10 new fish species that went on the naming auction block at the same time earlier this year brought in a total of $2 million.
The butterfly discovered by Warren and researcher George Austin ranges as far north as Mexico.
The butterfly was actually in a collection, misidentified as an example of another new species, at the McGuire Center for Lepidoptera and Biodiversity at the Florida Museum of National History in Gainesville, said Warren. They soon began the hard process of determining that it was indeed a “new” model of butterfly.
After checking photos and comparing it with other known species, they determined it was a separate species.Where did the researchers discover the new species of butterflies?
| A．In Sonora. | B．In Mexico state. |
| C．In a place in US. | D．Near the US-Mexico border. |
Why will the researchers sell the naming rights of the butterfly?
To raise money for wildlife protection.
To raise money for more research.
To cause people’s attention to the new discovery.
To cover the cost of the research.When the butterfly was first discovered, people thought ______.
it was a new species at once
it wasn’t a species of American butterfly
it belonged to the monarch branches
it belonged to a new species We can infer from the passage that ______.
the new species of butterfly live both in the US and Mexico
it took the researchers a lot of efforts to determine the new species of butterfly
the researchers are not sure whether they can get the money they want from the auction
it is the first time that the new species of butterfly has been found
The saying that children don’t like reading any more has been proved untrue. A new study finds that 75 percent of kids between five and 17 say that although they love technology, they still want to read books．
The Kids & Family Reading Report also says that 62 percent of kids prefer reading printed books rather than those on a computer．At the same time, those who search an author’s website or use the Internet to find books by a particular author, are more likely to read books for fun every day．
The study also once again proves that the time kids spend reading books for fun decreases after the age of eight and continues to drop through the teen years．The report is a follow-up to a 2006 study．But this time the focus is on the role of technology and when kids’ interest in reading starts to drop．
“Despite the fact that after the age of eight more children go online daily than read for fun daily, high frequency Internet users are more likely to read books for fun every day,” says Heather Carter, a writer of the report．
One in four kids between five and 17 say they read books for fun every day and more than half of kids say they read books for fun at least two to three times a week．One of the key reasons kids say they don’t read more often is that they have trouble finding books they like - a requirement that parents underestimate(低估)．
The study also finds that parents have a strong influence on kids’ reading, but only about half of all parents begin reading to their kids before their first birthday．The percent of children who are read to every day drops from 38 percent among five-to eight-year-olds to 23 percent among nine-to 11-year-olds - exactly the same time that kids’ daily reading for fun starts to drop．
“Parents’ engagement in their child’s reading from birth all the way through the teen years can have a great influence on how often their children read and how much they enjoy reading,” adds Carter．What can we learn from the text?
| A．Children don’t like reading any more after the age of 8. |
| B．Most children like reading as well as going online. |
| C．All kids like reading e – books instead of printed ones. |
| D．Most children like going online instead of reading. |
It can be inferred from the passage that .
| A．the study of kids’ reading has been made before |
| B．most parents begin reading to their kids from their birth |
| C．all kids like to get information using the Internet |
| D．nowadays all children still like to read books |
Which of the following is true according to the text?
| A．The kids who often go online don’t like reading books. |
| B．Parents should teach their kids reading from an early age. |
| C．Sometimes it is difficult for kids to get the books they like. |
| D．When kids get older, parents spend more time with them. |
According to the text,contributes a lot to children’s interest in reading.
| A．the Internet | B．parents’ engagement |
| C．short supply of books | D．new technology |
What’s the best title of the passage?
| A．Do kids still like reading? | B．Kids’ interest in reading drops |
| C．New technology on kids’ reading | D．Parents’ influence on kids’ reading |
