Recent discoveries of water and Earth-like soil on Mars have set imaginations running wild that human beings may one day control and send people to live on the Red Planet. However, the first to live there might not be human, but rather groups of tiny robots.
“Small robots that are able to work together could explore the planet. We now know there is water and dust so all they would need is some sort of glue to start building structures, such as homes for human scientists,” says Marc Szymanski, a robotics researcher at the University of Karlsruhe in Germany.
Szymanski is part of a team of European researchers developing tiny autonomous (自主的) robots that can co-operate to perform different tasks, much like ants or bees search for food together, build nests and work together for the greater good of the planet.
“A group of robots is particularly useful when one robot is damaged. It does not cause the task to fail because another robot simply steps in to fill its place,” Szymanski explains.
Several of the researchers have since gone on to work on creating groups of robots that are able to reassemble (重新装配) themselves autonomously into larger robots in order to perform different tasks.
Planet exploration and colonization (殖民) are just some of a seemingly endless range of potential applications for robots that can work together, adjusting their duties depending on the barriers they face, changes in their environment and the group’s needs. That is not only useful in space or in deep-water environments, but also while carrying out repairs inside machinery, cleaning up pollution or even applying treatments inside the human body.
66. What would be the main task of the groups of tiny robots on Mars?
A. To look for water and Earth-like soil. B. To remove barriers for human arrival.
C. To colonise the Red Planet. D. To build home-like structures.
67. Why are groups of tiny robots sent to Mars?
A. Because they work very fast in space.
B. Because they can work together to perform different tasks.
C. Because they can find all the building materials.
D. Because they are easy to control.
68. The tiny robots would NOT be used .
A. to work under the sea B. to repair machines
C. to protect the environment D. to try out new medicines
69. The last paragraph mainly tells us about .
A. potential applications for robots B. different kinds of robots
C. the barriers the robots face D. planet exploration and colonization
70. Which of the following statements is TRUE?
A. The tiny robots can work together with ants or bees.
B. There’s enough water on Mars for human existence.
C. The basic substances for human existence have been found on Mars.
D. The tiny robots can change to any size at any time.

Life gets noisier every day and very few people can be free from noise of some sort or another. It doesn’t matter where you live- in the middle of a modern city, or a faraway village the chances that you will be disturbed by jet planes , transistor radios, oil-powered engines, etc, are almost everywhere. We seem to be getting used to noise, too. Some people feel quite lonely without background music while they are working.
Scientific tests have shown that total silence can be very frightening experience for human beings. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums (耳鼓). The noise level in some disco is far above the usual safety level for heavy industrial areas.
One recent report about noise and concentration(专心) suggested that although a lot of people say that any noise disturbs their concentration , what really affects their ability to concentrate is a change in the level of noise. It goes on to say that a background noise, which doesn’t change too much (music, for example ) may even help people to concentrate.

JAMES Brown, the legendary US singer known as the “Godfather of Soul”, died Christmas morning, 2006. he was 73.
Brown was one of the major musical influences of the last
50 years. He provided the basis for much of black music and
most of pop music with his early hits like. “Please, Please,
Please”. He essentially created funk(“疯客”音乐)with
mid-1960s songs such as "Papa's Got a Brand New Bag".
It won him a Grammy Award as best rhythm-and-blues song,
and it was only the beginning of Mr. Brown's rhythmic
breakthroughs. His rapid-footed dancing inspired Michael Jackson and Prince. Rap stars of recent years, such as Fat Boys and Public Enemy, have all borrowed his lyrics and rhythms.
Brown's songs in the late 1960s and early 1970s, such as "Hot Pants" and "Make It Funky", mixed the sophistication(复杂) of jazz-style arrangements with raw funk. With these songs, Brown established himself as the godfather not just of soul, but of all subsequent styles of dance music: funk, disco, hip hop.
"He made soul music a world music," said Al Sharpton, who toured with Brown in the 1970s and imitates his hairstyle to this day. "What Brown was to music in terms of soul and hip hop, rap, all of that, is what Bach(巴赫, 德国作曲家) was to classical music. He put everybody on a different beat, a different style of music."
Amid the civil rights movement of the 1960s Mr. Brown used his fame and music for social messages. He released "Don't Be a Dropout" in 1966 and met with Vice President Hubert H. Humphrey to promote a stay-in-school initiative. Two years later "Say It Loud - I'm Black and I'm Proud" insisted, "We won't quit movin' until we get what we deserve."
