I finished training as a nurse in Auckland and I was expecting to get a job in a small hospital somewhere. But then a friend told me about Volunteer Now. I’d always wanted to go to an African country and use my nursing skills to help people. And here was a chance to do that, so I decided to apply.　 1. I got one hospital to sponsor me and then I borrowed some money from the bank.

So I went to Madagascar and joined a team of people working with a local supervisor (主管人). 2.

By going round villages, we taught basic ways to improve hygiene (卫生) and to avoid catching diseases. For example, we gave instruction about how to avoid catching malaria (疟疾) and distributed mosquito nets to some of the homes. I think we did some good. I hope so anyway.

3. I was suddenly in a completely different culture, teaching people who had such a different lifestyle from my own. It made a big difference to the way I see the world. And I also made some very good friends out there, both local people and the other volunteers.　 4.

After I came back, I got accepted straight away for a job at the university hospital. 5.I’m sure I wouldn’t have managed to do that if I hadn’t worked in Madagascar and got this practical experience.

A.We set up a program there.

B.I also got a lot from this program.

C.It is one of the best hospitals in Auckland.

D.So I’d recommend Volunteer Now to anyone.

E.I failed to take the opportunity though I could.

F.I had to raise $500 before I went, but that was quite easy.

G.We had such good times together and we’ve kept in touch since then.

Some people think that as more and more people have televisions in their homes, fewer and fewer people will buy books and newspapers. Why read an article in the newspaper, when the TV news can bring you the information in a few minutes and with pictures? Why read the life story of a famous man, when a short television program can tell you all that you want to know?

Television has not killed reading, however. Today, newspapers sell in very large numbers. And books of every kind are sold more than ever before. Books are still a cheap way to get information and enjoyment. Although some books with hard covers are expensive, many books are printed today as paperbacks (平装本), which are quite cheap. A paperback collection of short stories, for example, is always cheaper than an evening at the cinema or the theater, and you can keep a book for ever and read it many times.

Books are a wonderful provider of knowledge and pleasure and some types of books should be in every home. Every home should have a good dictionary. A good encyclopedia (百科全书), though expensive, is useful, too, because you can find information on any subject. Besides, you can have such books as history books., science textbook, cookbooks, and collections of stories and poems. Then from time to time you can take a book of poems off your shelves and read the thoughts and feelings of your favorite poets.

1.It can be inferred from the passage that ________.

A.TV programs are a chief provider of knowledge

B.cinemas are the best choice in getting information

C.reading is a cheap way of learning and having fun

D.newspapers are an expensive way to enjoy oneself

2.What does the sentences “Television has not killed reading, however ” underlined in the second paragraph suggest?

A.People only need reading, though. B.Reading is still necessary today.

C.Reading is more fun than television. D.Watching television doesn’t help reading.

3.What can we learn from the passage?

A.Fewer and fewer people will buy books.

B.A good dictionary should be kept in every home.

C.Books with hard covers sell better than paperbooks.

D.More people like TV programs about famous men.

Hannah McKeand was born in Bristol in 1973. She got a degree in Classics at Lampeter University. After working as a marketing manager, she decided at the age of 31 to devote herself entirely to her primary passions (热情), exploring, adventure and the outdoors. She would take part in various expeditions (探险), in the Egyptian desert first, then in the remote valleys of northeast of Afghanistan, and then in Antarctica.

In 2001 her urge to explore began to develop with a trip to the Western Desert on the borders of Egypt, Libya and Sudan in search of prehistoric rock art. This trip took Hannah to the center of the second biggest wilderness on the planet, an uninhabited (无人居住的) area the size of India.

In 2004 Hannah joined a British expedition to explore the Wakhan Corridor in the northeast of Afghanistan in search of the source of the River Oxus. The upper (上部的) areas of this mountain valley had rarely been visited by Westerners.

Later that year Hannah turned to a cold desert in a 56-day expedition from the coast of Antarctica to the South Pole. Crossing one of the harshest (最严酷的) environments in the world, the team of five battled with physical and mental exhaustion, injury, hunger and some of the lowest temperatures on earth.

In 2006 Hannah returned to Antarctica and once again skied from Hercules Inlet to the South Pole, but this time alone and unsupported. She set a new world record for the journey of 39 days 9 hours and 33 minutes.

In October 2007 Hannah began her first full adventure season traveling from Australia across to Chile and from there around Cape Horn and down to Antarctica.

Hannah hopes that by writing and speaking about her experiences in the world and sharing them with those who care to read or listen, she will inspire people to go after their own dreams and achieve their own goals.
