In the African country of Tanzania, a company from Belgium called APOPO trains African giant pouched rats(非洲巨袋鼠) to find dangerous land mines(地雷)left over from wars. The rats are trained to smell out some of the chemicals in the mines. After 8-12 months of training, the rat can find mines so they can be safely destroyed.

       Trained dogs often perform this important work, but APOPO director Bart Weetjens recently discovered that the African giant pouched rat costs far less money to train and care for. These rats may seem huge. Their bodies are 12 to16 inches long, not including their tails. But their size suits the job: At one and a half to 3 pounds, they are too light to set off the land mines.

       Rats and trainers search one small area at a time. When a rat smells mines, it lets the trainers know by pawing(用爪子抓)at the dirt in that spot. The trainers mark each spot on a map. Later, technicians explode the mines safely. In the African country of Mozambique, nearly half the population is younger than 15 years old. A lot of kids are in danger as they play or work.

       “In the town of Vilanculos, children had been playing on the football field, until there was an accident,” Bart Weetjens said. APOPO rats and trainers helped other organizations make the area safe. “The football field has been opened again, and there is no danger any more,” Weetjens said.

       About 80 million land mines are buried out of sight in more than 60 countries around the world. As APOPO’s program grows, the rat heroes might travel the globe!

1．The underlined word “they” (Para. 1) refers to_____.

       A．the trainers                     B．the mines                C．the wars                 D．the rats

2．Why are rats chosen to be trained to find the land mines?

       A．They are native to Africa                      B．They are smarter than dogs

       C．They are cheap to keep and train           D．They are quick to escape from danger

3．What is the task of the rats in the job?

       A．To mark a map                                    B．To find the mines

       C．To set off the mines                             D．To paw at the ground

4．What happened on the football field in Vilanculos?

       A．A land mine exploded                           B．A player was injured during the training

       C．The children were attracted by the rats  D．The villagers tried to get the field back

The majority of astronauts from America have been men. At the start of the space programme there was strong resistance from some people against having women in space. However, some women were very keen to become astronauts and in the end they were successful. In 1978, NASA began the first training programme for women astronauts.

Judy Resnick and Christa McAuliffe were both astronauts and they were both women, but in many other ways they were very different. Both of them were on Flight STS-5L-L. Judy Resnick was born in 1949 and studied engineering at university and went on to obtain a PhD in 1977. She was a member of the first group of women selected for astronaut training in 1978, and in 1984, she became the second woman in space. During that flight, she helped to launch three new satellites and she carried out a programme of research. She was, in many ways, a professional astronaut whose whole life was devoted to space travel.

Christa McAuliffe was born in 1948 and she was an astronaut almost by accident. In 1984, NASA decided to find a teacher who could accompany astronauts into space. They hoped that she would be able to communicate with students from space and encourage every one of them to be interested in space travel. Christa was a secondary teacher in history and social studies. She was a gifted teacher and she was selected from over 11,000 applicants to go on flight STS-51-L. She was also a very good communicator and she immediately established a very good relationship with the news media(radio, television and newspapers）. It was partly because of this that there was a great deal of interest and excitement about the flight. Thousands of students in schools and universities all around the country were looking forward to communicating with Christa in space. Millions of people were watching her flight with great interest. It is partly because of the excitement over McAuliffe's place in the flight that the disaster in 1986 had such an effect on people.

We can learn from the first two paragraphs that ___________.

A. Judy was against the idea of having women in space at first

B. Judy was the first woman selected for astronaut training

C. Judy helped to launch three new satellites at the age of 35

D. Judy carried out a programme during her second space travel

Christa McAuliffe was chosen for training because _______.

A. she was popular with the news media

B. she expected to give history lessons in space

C. she was an excellent teacher and communicator

D. she made the students in space very excited

The reason why there was great interest in Flight STS-51-L is that ________.

A. both Christa and Judy got PhD degrees in the same year

B. a young secondary school teacher was on the flight

C. students were going to learn more about space travel

D. it was the first time for women to travel in space

What would be the best title for the passage?

 A. Two Astronauts         B. Flight STS-51-L

C. Travelling in Space       D. The Training Programme

Laws that would have ensured pupils from five to 16 received a full financial education got lost in the ‘wash up’．An application is calling on the next government to bring it back.

At school the children are taught to add up and subtract（減法） but, extraordinarily, are not routinely shown how to open a bank account — let alone how to manage their finances in an increasingly complex and demanding world.

Today the parenting website Mumsnet and the consumer campaigner Martin Lewis have joined forces to launch an online application to make financial education a compulsory element of the school curriculum in England．Children from five to 16 should be taught about everything from pocket money to pensions, they say．And that was exactly the plan preserved in the Children, Schools and Families bill that was shelved by the government in the so-called “wash-up” earlier this month — the rush to legislation before parliament was dismissed．Consumer and parent groups believe financial education has always been one of the most frustrating omissions of the curriculum.

As the Personal Finance Education Group (Pfeg) points out, the good habits of young children do not last long．Over 75% of seven- to 11-year-olds are savers but by the time they get to 17, over half of them are in debt to family and friends．By this age, 26% see a credit card or overdraft（透支） as a way of extending their spending power．Pfeg predicts that these young people will “find it much harder to avoid the serious unexpected dangers that have befallen many of their parents' generation unless they receive good quality financial education while at school.”

The UK has been in the worst financial recession（衰退）for generations．It does seem odd that — unless parents step in — young people are left in the dark until they are cruelly introduced to the world of debt when they turn up at university．In a recent poll of over 8,000 people, 97% supported financial education in schools, while 3% said it was a job for parents．

The passage is mainly about _____________.

       A．how to manage school lessons

       B．how to deal with the financial crisis

       C．teaching young people about money

       D．teaching students how to study effectively

It can be inferred from the first two paragraphs that __________.

       A．the author complains about the school education

       B．pupils should not be taught to add up and subtract

       C．students have been taught to manage their finances

       D．laws on financial education have been effectively carried out

The website and the consumer campaigner joined to _________.

       A．instruct the pupils to donate their pocket money

       B．promote the connection of schools and families

       C．a(chǎn)sk the government to dismiss the parliament

       D．a(chǎn)ppeal for the curriculum of financial education

According to Pfeg, ___________.

       A．it is easy to keep good habits long

       B．teenagers spend their money as planned

       C．parents are willing to pay the debt for their kids

       D．it will be in trouble if the teenagers are left alone

A poll is mentioned to ___________.

       A．stress the necessity of the curriculum reform

       B．show the seriousness of the financial recession

       C．make the readers aware of burden of the parents

       D．illustrate some people are strongly against the proposal

     The Notting Hill Camival (諾丁山狂歡節(jié)) has been taking
place in London, on the last weekend in August, every year since
1964.
       This great festival began with the Black immigrants(黑人移
民) from the Caribbean, particularly from Trinidad, where the
Camival tradition is very strong. People there dreamed of creating
a festival to fight against racism (種族主義).  At that time, they

poor.
