Question: Article: I bought a Paul Smith shirt three months ago. For those who don't know, Paul Smith is an English designer brand. His shirts cost about 1,000 yuan and upwards. I paid 50 yuan for my colorful shirt from a street vendor in Beijing. Of course my shirt was a knockoff, a cheap copy of the brand. After a few washes, little balls formed on the surface of the thin material. Do I care? Not at all. You get what you pay for. I have to admit I hate shopping. _ I have other priorities. In You Are What You Wear, US writer Jennifer Baumgartner says people's clothes tell a story about their personality. She writes: "The clothes you choose to wear provide important information about you as a person: your approximate education level, your income, social status and even your level of self-esteem ." When I started work as an undercover crime reporter, I had to shop for jeans and a hoodie in order to fit in with a rough and ready social group. I bought the hoodie in a charity shop. My daughters were shocked. They thought I looked bad, but I knew my disguise was perfect. Elizabeth L. Cline thinks she knows best when it comes to cheap clothes in her book Overdressed: The Shockingly High Cost of Cheap Fashion.

Question: Article: Edmund Halley was an English scientist who lived over 200years ago. He studied the observations of comets which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems. However, Halley had a friend named Isaac Newton. Who was a brilliant mathematician. Newton thought he had already which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse. Now Halley set to work. He figured out the orbits of some of the comets that had been observed by scientist. He made a surprising discovery. The comets that had appeared in the years 1531, 1607 and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart. This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets, as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again. It was an astonishing idea! Halley felt certain enough to make a prediction of what would happen in the future. He decided that this comet would appear in the year 1758. There were 53 years to go before Halley's prediction could be tested. In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet been called Halley's comet, in his honor.
