What will you be doing when you are 26 years old? Studying at university or working for a living? Take a look at what Albert Einstein was doing at the age of 26. 100 years ago, Einstein was working in Switzerland. His hobby was physics. Without much money or help, he wrote five papers for a physics magazine. Three of these greatly changed the study of physics and our understanding of space, time, light and matter . His most famous work is on the Theory of Relativity . Einstein was given the Nobel Prize for his discoveries. Although he also did many other things later, the years 1905 has been called Einstein's "Year of Wonders". It has been 100 years since then. Because of this, the UN has named 05 the World Year of Physics. Today, over fifty years after Einstein's death, a question is asked, " Will there ever be another Einstein?" It may take a long time. After all, Einstein was born more than 200 years after Sir Isaac Newton, another great scientist. Besides, physics is a different field now, and education is different, too. Even if you can't be the next great scientist, it is still helpful to remember some of the things that made Einstein great. He thought independently and read widely. He left with us a formula for life: If A is a success in life, then A="X+Y+Z." X is work, Y is play, and Z is keeping your mouth shut. Why hasn't there been another scientist as great as Einstein? A) Because the study of physics is not enough. B) Because it is hard to make important discoveries as Einstein did. C) Because people don't work hard any more. D) Because physics is getting more and more difficult.

Counterfeit ( ) medicines are a widespread problem in developing countries. Like other counterfeits, they look like real products. But counterfeit drugs may contain too little or none of the active ingredients of the real thing. People do not get the medicine they need. And in some cases counterfeits cause death. Twenty children in Bangladesh died last year after being given acetaminophen . The medications contained ingredients that looked, smelled and tasted like the real thing. The medicine was produced by a local drug company that used a dangerous substitute to save money. The problem of counterfeit medicines is especially serious in Africa, Asia and Latin America. The W.H.O. estimates that up to thirty percent of medicines on sale in many of those countries are counterfeit. The problem is less widespread among industrialized countries. The W.H.O. says counterfeits make up less than one percent of the illegal drug market in countries like the United States, Canada, Japan, and New Zealand. But the agency also says as much as fifty percent of the medicine sold on the Internet is counterfeit. Much is being done to fight counterfeit drugs. Several companies are developing ways to make counterfeits easier to identify. And there are existing methods, like a machine that can quickly identify chemicals in pills to confirm if the pills are real. Other ideas include things like special tracking codes for drug packages. People could send a text message with the code and get a message back, which proves that what they bought is listed in a database. Some drug makers and other companies put three-dimensional images called holograms on their products as a security device. We can draw a conclusion from the passage that _ . A) it is very cheap and convenient to buy medicines online. B) medicine companies don't pay much attention to counterfeit drugs. C) more and more people will buy products online. D) we had better not buy medicines online.

Q: We often find that weekends and holidays feel so short while classes and work feel so long. In reality, though, we know that this is not true. But we still wonder where that strange feeling comes from. In fact, this is one of the ways that we're tricked by time, according to the website All That Is Interesting. The website lists several wrong impressions we often have about time. Let's have a look. First of all, emotions affect our time-keeping abilities: Negative emotions, especially anxiety and boredom, make time seem longer because they make us concentrate more on the passage of time. However, when we are enjoying ourselves, we pay more attention to what we are doing and are likely to lose track of(...) time. Here is another example. In 2007, a group of scientists carried out a test. In the test, people fell 50 meters into a safety net and were then asked about their experience. Although the experience took shorter than 3 seconds, the people thought it was much longer than it actually was. This is because of the way our bodies reply to danger, according to the scientists. Our bodies produce a chemical called adrenaline when we are faced with danger. It allows us to concentrate better so that we can stay alive. As a result, we are able to remember far more details over a short period of time, which makes it seem like time is going more slowly. Another occasion when we make mistakes about time is when we take afternoon naps . Have you ever had trouble telling what time it is after a long nap? That's because the best amount of time for a nap is 20 minutes. After 20 minutes, you enter a new stage of sleep called slow-wave sleep. If you wake up mid-way in this stage, it will take a while before you can correctly perceive time again. Yes, time can be mysterious and there is no way to control it So, perhaps the best thing to do is to make good use of every minute. What is the article mainly about? A) How emotions affect time keeping abilities. B) Tests which scientists carried out about time. C) The best amount of time for an afternoon nap. D) Mistakes that people make in their understandings of time.

(Q).
About a year ago, I went to stay at a Detroit hotel. I didn't want to carry too much money with me, so I asked the desk clerk to put a one-hundred-dollar bill in the safe for me. The next morning, however, the clerk said he knew nothing about my money. I didn't have any proof that I had given the man the money. There was nothing I could do but go to the nearest lawyer. The lawyer advised me to return to the hotel with him and give another one-hundred-dollar bill to the clerk. This I did. An hour later, I went back to the desk alone and asked for my money. Since I had the lawyer as an eyewitness to the second one-hundred-dollar bill, the clerk could not say he knew nothing about it. Another hour later, I put the second part of the lawyer's plan into action. This time both the lawyer and I went to the hotel. I asked for the one-hundred-dollar bill once again, and when the clerk insisted he had already given it to me, I denied it. The lawyer said to him, "I saw this gentleman give you a hundred dollars. If you don't hand it over immediately, I'll be forced to call the police." The clerk realized he had been tricked, so he gave me back the first one-hundred-dollar bill. "I don't know how to thank you enough for getting my money back," I said to the lawyer. And what do you suppose he answered me? He said, "Oh, don't thank me. That will be a hundred dollars, please." The man went to a Detroit hotel one day to _ . A) get his money back B) put a hundred-dollar bill in the safe C) ask to be a desk clerk D) stay for the night
