Cholera used to be one of the most feared 【小题1】 (disease) in the world, until a British doctor John Snow 【小题2】 (show) that it could be overcome. 【小题3】 general, doctors in those days had two contradictory theories to explain 【小题4】 cholera spread. But Snow subscribed 【小题5】 the second one. When an outbreak of cholera hit London in 1854, Snow discovered that in two particular streets the cholera outbreak was 【小题6】 severe that more than 500 people died in ten days. Later, he found the truth 【小题7】 the water from the Broad Street pump 【小题8】   (infect) by waste. And the people who drank this water were much more likely 【小题9】 (get) cholera than those who drank pure 【小题10】 boiled water.

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 【小题1】 practising their music in someone’s house 【小题2】 (be) the first step to fame. Sometimes they may play to 【小题3】 (passer-by) in the street or subway so that they can earn some extra money for themselves or to pay for 【小题4】 (they) instruments. Later they may give performances in pubs or clubs, for which they 【小题5】 (pay) in cash. Of course they hope to make records in a studio and sell millions of copies 【小题6】 (become) millionaires!

However, there was one band that started in a different way. It was called 【小题7】 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 【小题8】 (loose) 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, 【小题9】 they could only find one who was good enough. They 【小题10】 (have) to use actors for the other three members of the band.

Colors 【小题1】 (consider) one of the most useful and powerful design tools you have. People respond to different colors in different ways. Colors tell someone if you are 【小题2】 (friend).

Different cultures have different attitudes and 【小题9】 (prefer), so they will have another color reaction. People from warm countries respond favorably to warm colors j people from colder climates prefer cooler colors. In America, green is associated with jealousy or money.
