A private group of scientists has announced plans to make an exact copy of a human being. An American member of the team says he and the others will soon begin a serious effort to clone humans. Panos Zavos says the team hopes to manufacture the world’s first cloned baby within the next two years.
In recent years, scientists have produced exact genetic copies of sheep and a few other animals. They created these clones from a single cell of an adult animal.
Three years ago, another American doctor, Richard Seed, announced plans to clone a human being. However, there is no evidence that he has been successful.
Doctor Zavos says the new international group plans to offer human cloning only to women who are currently not able to become pregnant or produce children. He says the aim is to assist people who want to have their own biological child.
The technology would be similar to that used to clone animals. It would involve cleaning genetic material from a woman’s egg. Doctors then would place genetic material from the woman’s husband into the egg before putting it into the woman’s uterus(子宫).
Doctor Zavos says his group plans to do the work in a country near the Mediterranean Sea. He did not name the country. He says an Italian reproductive expert, Sevorino Antinori, is leading the team. Doctor Antinori has led the efforts to help many older women become pregnant. He is known for establishing pregnancies in women as old as sixty.
Many medical experts and other groups are opposed to the idea of cloning humans. Several countries ban or restrict work on human cloning. Several doctors criticize the announcement by Doctor Zavos. They say doctors do not know if cloning humans is possible or safe. They say it would be irresponsible to attempt to clone a human being. That is because the chances of success are too small and the risks are too great.
1.The underlined word “manufacture” in the first paragraph means “_________”.
A．produce B．oppose C．attempt D．experiment
2.Which of the following statements is TRUE?
A．In theory, scientists are unlikely to clone humans.
B．Richard Seed has fallen behind other scientists in cloning humans.
C．Cloning human beings is good for men.
D．People have different ideas about cloning humans.
3.How do many medical experts and other groups like the idea of cloning humans？
A．They are in favour of the idea.
B．They are against the idea.
C．They have an optimistic attitude to the idea.
D．They think it is none of their business.

NASA has opened the door to the next generation of space discovery by announcing great plans for a base for humans to live on the surface of the moon forever.
The project to build a base on the moon will begin soon after 2020, with astronauts living there within four years.
The project comes after several excellent scientists and environmentalists asked humans to look beyond Earth to ensure the survival of the species (物种).
Eventually, the moon will be a base for humans to explore the solar system and one day land on Mars.
NASA began planning for the first moon landing since 1972 when George Bush, the US president, announced his new plan for space exploration four years ago.
NASA has already talked about the design of the Orion spacecraft that will replace the old space shuttle fleet in 2010.
The plan for the moon base, however, is the first detailed explanation of how NASA intends to prepare for the first manned exploration of deep space and a possible Mars mission within 30 years.
Scientists also believe that the south pole on the moon contain rich natural gases such as the rare helium-3 that could be used as fuel for the generation of nuclear power. Besides, teams of astronauts living there for six months at a time would mine for hydrogen and oxygen to make water and possibly rocket fuel.
1.The reasons why NASA has begun the plan to explore space include the followings except ________.
A. to protect Earth
B. to explore deep space
C. to finish Mars mission
D. to show how powerful the USA is
2.In the future, when people fly to the moon, they will probably not bring with them too much ________
A. hydrogen B. food C. oxygen D. water
3.The passage mainly talks about ________.
A. the USA’s new plan for space exploration
B. how to build a base on the moon
C. why to ensure the survival of the species
D. where to get new natural resources

An allowance(零花钱) is an important tool for teaching kids how to make plans for the use of money, save and make their own decisions. Children remember and learn from mistakes when their own dollars are lost or spent foolishly.
How large an allowance is suitable? Experts say there is not right amount. Actual amounts differ from region to region, and from family to family.
To set an suitable allowance for your child, work up a weekly plan. Allow for entertainment costs such as movies and snacks. Next, include everyday expenses such as lunch money, bus fare, school supplies. "If you make the child responsible for these bills’," says Josephine Swanson, a consumer specialist, " he or she will learn to plan for necessary costs."
Finally, add some extra money to make saving possible. If you can keep your child’s allowance in line with that of his friends. A child whose buying power falls away below his peers’ can feel left out.
It can be tough, but don’t excuse your children when they make a mistake with their allowance. When Brooke Stephens was ten and growing up in Jacksonville, her mother gave her $5 a week, $1.75 of which was for bus fare and lunch." If you lose your money," Brooke’s mother told her, "you walk home."
One week the girl spent all her allowance in a candy store, then she called home for a ride. " Mom made me walk home," recalls Stephens, now a financial planner in Brooklyn. " At first I was angry. But I finally realized that she was trying to teach me an important lesson. "
Experts advise that an allowance should not be tied directly to a child’s daily housework at home. Kids should help around the house not because they get paid for it but because they share responsibilities as members of a family. You might, however, pay a child for doing extra jobs at home, which can develop his or her early habits.
1.Which of the following is the possible title of the passage?
A．How to develop a child’s early habits.
B．How to work up an amount of pocket money.
C．How to teach a child about money.
D．How to teach a child to save money.
2. It can be inferred from the passage that if a child is given an allowance, he or she may ________.
A．spend all the money very soon
B．fall into the bad habit of wasting money
C．feel responsible and careful about money
D．lose the money and can not return home
3. In Paragraph 4, the words “his peers” refer to ________.
A．his parents B．his friends
C．his financial experts D．his teachers
4. Why does the writer mention Brooke Stephens?
A．To question the opinion about pocket money.
B．To compare Stephens with other financial experts.
C．To explain that parents should be strict when children are developing good habits about money.
D．To suggest pocket money is useless in developing a child’s sense of responsibility.
5. The writer implies in the passage that ________.
A．children may feel lonely if they have no pocket money
B．a child’s early good habits can be developed if he or she is paid for all the housework
C．paying children for their housework is no good
D．children may learn to put aside some money if they are given a great amount of pocket money

BERLIN (Reuters)—Germany’s postal service has announced plans to explore improved service and help protect the environment by getting “fetch friends”—ordinary people traveling across cities—to deliver parcels on their way.
It is hoped that the move, which will be tested in the coming months, might lessen traffic in inner cities and reduce CO2 emissions(排放). This should help DHL, a division of the German postal service, reach its target of improving the company’s carbon efficiency by 30 percent before 2020.
“As the world’s biggest logistics(物流) provider, we recognize a special responsibility to reduce the impact on the environment as much as possible,” said Frank Appel, Chief Executive Officer of Deutsche Post DHL, in a statement referring to a variety of measures being considered.
The “fetch friends” find out online about parcels that need delivering to people who live or work along the way that they are planning to travel through the city. They then select the ones that they want to take.
Codes(编码) sent to their mobile phones tell the volunteers where to pick the packages up. Parcels can be taken part of the way or passed on to another volunteer but all volunteers need to have the right code on their mobile phone so the track and trace system can be updated.
Logistics companies will be responsible for looking after the operation to make sure that the privacy of post is respected.
It’s hoped that this could be done using mobile phones but DHL says it recognizes that some security issues remain to be worked out.
1.According to the passage, the “fetch friend” program ________.
A. has been tested for months
B. aims to reduce the cost of the service
C. employs environmentalists to help with deliveries
D. encourages ordinary people to help cut the carbon footprint
2.Which of the following statements is TRUE of DHL?
A. It belongs to the Germany’s postal service.
B. It has the most up-to-date tracking system in Germany.
C. It has succeeded in improving its carbon efficiency by 30%.
D. It has designed many measures to improve its service speed.
3.What may be a problem with the new service according to the article?
A. Volunteers’ not allowing to select parcels.
B. The wrong codes in the mobile phones.
C. The possibility that parcels could be opened on the way.
D. Parcels’ being taken to the destination by a single volunteer.
4.What might be the best Title for the best passage?
A. New Challenges for the Postal Service
B. A Greener Way to Deliver Parcels
C. Solutions for Global Warming
D. Statements from DHL

Endurance (耐力) cyclist Mark Beaumont has announced plans to go around the world in 80 days on his bike, which would break the present record. To be successful, Beaumont will have to complete the 18,000 mile route in less than half the time he took when he set the record nine years ago. He will also have to knock about 40 days off the present world record.
Beaumont, 34, will begin his difficult journey on 2 July and will have to travel 240 miles a day to get around the world on time. Beaumont set the world record in 2008, completing his cycle around the globe in 194 days.
As a warm-up to the trip, he will first cycle around the coastline of Britain. The 3,500-mile, 15-day training ride will be at “80 days” pace and will see Beaumont cycle for 16 hours and 240 miles per day.
The cyclist said his average day would see him on the bike at 4:00 and riding for four sets of four hours with half-hour breaks in between. “I’ll get off the bike at 9:30 at night, get some sleep until the alarm goes off at 3:30 and then get back on the bike.”
He said: “I cycled around the world nine years ago but that was unsupported, wild man-style, trying to find clean water and a place to sleep. This time it is Tour De France-style. I have a support team behind me and it is just about performance. That makes a huge difference.”
Beaumont said he thought cycling round the world “sounds like a good idea”. He said he had cycled across Scotland as a 12-year-old boy and had been doing endurance rides for the past 20 years. “I know what I’m taking on,” he said. “It scares me, but I believe this is possible.”
1.What’s the present around-the-world-cycling record?
A.About 40 days. B.80 days.
C.About 120 days. D.194 days.
2.What’s Beaumont’s plan for his coming world tour?
A.He will take part in a 15-day training first.
B.He cycles16 hours and 240 miles per day.
C.He starts cycling at 3:30 am every day.
D.He will have two breaks during the cycling every day.
3.Compared with the 2008 world tour, the advantage of the coming tour is that ________.
A.Beaumont has a support team
B.it will probably cost less money
C.Beaumont needn’t find places to sleep
D.the cycling equipment is more advanced
4.How did Beaumont feel about the coming world tour?
A.Excited. B.Scared.
C.Confident. D.Uncertain.
