请阅读Passage l。完成第21—25小题。Passage 1It's one of our common beliefs that mice are afraid of cats. Scientists have long known that even if a mouse has never seen a cat before, it is still able to detect chemical signals released from it and run away in fear. This has always been thought to be something that is hard-wired into a mouse s brain.But now Wendy Ingram, a graduate student at the University of California, Berkeley, has challenged this common sense. She has found a way to"cure" mice of their inborn fear of cats by infecting them with a parasite, reported the science journal Nature.The parasite, called Toxoplasma gondii, might sound unfamiliar to you, but the shocking fact is that up to one-third of people around the world are infected by it. This parasite can cause different diseases among humans, especially pregnant women--it is linked to blindness and the death of unborn babies.However, the parasite's effects on mice are unique. Ingram and her team measured how mice reacted to a cat's urine(尿) before and after it was infected by the parasite. They noted that normal mice stayed far away from the urine while mice that were infected with the parasite walked freely around the test area.But that's not all. The parasite was found to be more powerful than originally thought—even after researchers cured the mice of the infection. They no longer reacted with fear to a cat's smell,which could indicate that the infection has caused a permanent change in mice's brains.Why does a parasite change a mouse's brain instead of making it sick like it does to humans?The answer lies in evolution."It's exciting scary to know how a parasite can manipulate a mouse's brain this way," Ingram said. But she also finds it inspiring."Typically if you have a bacterial infection, you go to a doctor and take antibiotics and the infection is cleared and you expect all the symptoms to also go away."She said, but this study has proven that wrong."This may have huge implications for infectious disease medicine."The passage is mainly about__________.查看材料

Have you ever dreamed of playing in front of thousands of people at a concert, at which everyone is clapping and appreciating your music? Do you sing karaoke and pretend you are a famous singer like Song Zuying or Liu Huan? To be honest, a lot of people attach great importance to becoming rich and famous. But just how do people form a band?Many musicians meet and form a band because they like to write and play their own music.They may start as a group of high-school students, for whom practicing their music in someone's house is the first step to fame. Sometimes they may play to passers-by in the street or subway so that they can earn some extra money for themselves or to pay for their instruments. Later they may give performances in pubs or clubs, for which they are paid in cash. Of course they hope to make records in a studio and sell millions of copies to become millionaires!However, there was one band that started in a different way. It was called the Monkees and began as a TV show. The musicians were to play jokes on each other as well as play music, most of which was based loosely on the Beatles. The TV organizers had planned to find four musicians who could act as well as sing. They put an advertisement in a newspaper looking for rock musicians, but they could only find one who was good enough. They had to use actors for the other three members of the band.As some of these actors could not sing well enough, they had to rely on other musicians to help them. So during the broadcasts they just pretended to sing. Anyhow their performances were humorous enough to be copied by other groups. They were so popular that their fans formed clubs in order to get more familiar with them. Each week on TV, the Monkees would play and sing songs written by other musicians. However, after a year or so in which they became more serious about their work, the Monkees started to play and sing their own songs like a real band. Then they produced their own records and started touring and playing their own music. In the USA they became even more popular than the Beatles and sold even more records. The band broke up about 1970, but happily they reunited in the mid-1980s.They produced a new record in 1996, with which they celebrated their formal time as a real band.
