PRINTER
Hamaki UK’s new DFG-2OO0 Bubble Jet printer is ideal for anyone looking to add colour to serious documents and presentations, and is an upgrading of last year’s DFG-15. Outstanding graphics make it a leading printer in its class, ideal for a business looking for quality, although its price may put it out of the reach of most private users. The unit can reproduce the finest details and its extended palette of colours means that a wide variety of images can be produced. Operated using software that can spot user errors before they result in poor printing, the machine has a simple two-button control panel. It is also very user-friendly and easy to install.

[单项选择]
Work looks a better cure for poverty than welfare Especially as fewer and fewer countries will be able to afford to pay potential workers to stay at home a Victorian idea is back in favour: many poor people are better off when they are pulled back into the labour market. The idea revived first in the United States. There, in its harshest form, the unemployed work in exchange for welfare. But countries with governments to the left of America’s, including Labour Australia and Socialist France, are now also exploring ways to link income support and employment policy.
Coming from different directions, the right and the left are gradually finding new common ground. For the right, it seems deplorable to encourage the poor to rely on the state for cash, because they get hooked on government help and accustomed to being poor. For the left, it seems deplorable to allow workers to drop out of the job market for long periods, because it makes it harder for them to find new job
A. more people have lost their jobs
B. many countries have done all they call for the poor
C. poverty has increased uncontrollably
D. more people are in the safety-net category

Pop Music in Africa
Young musicians in African countries are creating a new kind of pop music. The tunes and the rhythms of their music combine African traditions with various forms of music popu-lar today,such as hip-hop,rap,rock,jazz,or reggae. The result is music that may sound fa-miliar to listeners anywhere in the world,but at the same time is distinctly African. It is dif-ferent also in another way:Many of the songs are very serious and they deal with important social or political issues in Africa today.
Eric Wainaina is one of these African musicians.He grew up in Nairobi,Kenya,in a family of musicians.As a teenager,he listened to pop music from the United States,and lat-er he moved to Boston to study at the Berklee College of Music. Now he has produced a CD in Kenya. Eric's most popular song,“Land of ‘A Little Something’”,is about Kenya's problem of bribery,or paying others for illegal favors.He wants people to listen to his songs and think about how to make Kenya a better place to live.
Another musician who writes serious songs is Witness Mwaijaga from Tanzania. Her own experiences have helped her understand the suffering of many African women. At the
age of fifteen she lost her home,but she was luckier than other homeless young people. She could make a living by writing songs and singing on the street. By the time she was eighteen years old,she had become a star. Her songs are written in rap or hip-hop style about the problems that she sees in Tanzania,especially AIDS and the lack of rights for women.
Baaba Maal,from Senegal,also feels that pop music must go beyond entertainment.He says that in Senegal,storytellers have always been important people. In the past,they were
the ones who kept the history of their people alive. Baaba believes that songwriters now have a similar responsibility. They must write about the world around them and help people under-stand how it could be better. The words of his songs are important,in fact.They speak of peace and cooperation among Africans,as well as therights of women,love for one's family, and saving the environment.
One of South Africa's most popular musicians is Brenda Fassie. She is sometimes corn-pared to Madonna,the American pop star,because she likes to shock people in her shows.
But she also likes to make people think. She became famous in the 1980s for her simple pop songs against apartheid. Now that apartheid has ended,her songs are about other issues in South African culture and life. To sing about these,she uses local African languages and a new pop style called kwaito.
In recent years,people outside of Africa have also begun to listen to these young musici-ans.Through music,the younger generation of Africans are connecting with the rest of the world and,at the same time,influencing the rest of the world.
