Q: Read the following article and answer the question. Article: We live in a sweet world. The average American kid eats more than 20 teaspoons of sugar per day, and adults eat 50% more sugar today than they did in the 1970s. We all know that too much sugar isn't good for you. But did we know it could be dangerous? A team of researchers at the University of Utah used mice to do a study on the bad effects of sugar. They found it could have serious effects on people's health. Sugar is found not only in sweets and candies, but also in many household items like pasta and crackers. During the 58-week-long study, mice were fed a diet containing 25% more sugar. This percentage equals a healthy human diet along with three cans of soda daily. The team found that these mice were twice as likely to die as mice fed a similar diet without the sugar. Though the mice did not show signs of obesity or high blood pressure, male mice produced 25% fewer offspring than the other mice. Scientists often use mice for research because they have a similar genetic structure to humans. "Since most substances that are dangerous in mice are also dangerous in people, it's likely that those physical problems that cause those mice to have increased deaths also work in people,"says study author James Ruff of the University of Utah. Findings from this study show bad effects that are not as noticeable as weight gain or heart problems. Sugar can contribute to long-term changes in the body that can change development and even shorten lives. Cutting sugar out of the American diet altogether may be difficult. But making the effort to control our nation's sugar need will provide for a truly sweeter future. Question: From the passage we can infer _ Answer: | OPTIONS:
- sugar plays a very important role in Americans' diet
- kids eat more sugar than adults in America
- the study on human beings lasted 58 weeks
- the genetic structure of mice is totally different from that of people
A: sugar plays a very important role in Americans' diet

Q: Read the following article and answer the question. Article: An old and very rich friend of mine told me he had an unpleasant experience. He went to a famous jewelry shop and asked to be shown some gold necklaces. After examining several minutes, he decided to buy a gold necklace with a precious diamond, and asked if he could pay by cheque . The assistant said that was quite in order, but the moment my friend signed his name, he was invited into the manager's office. The manager was very polite, but he explained that someone with exactly the same name had given them a worthless cheque not long ago. My friend got very angry when he heard this and said that he would buy a diamond necklace somewhere else. When he got up to go, the manager told him that the police would arrive at any moment and he had better stay unless he wanted to get into serious trouble. Sure enough, the police arrived soon afterwards. They were polite, too, but explained that a person who had used the same name as his was responsible for a number of recent robberies. Then the police asked my friend to copy out a note which had been used by the thief in a number of stores. The note read, "I have a gun in my pocket. Ask no question and give me all the money in the drawer." Luckily, my friend's handwriting was quite unlike the thief's. He was not only allowed to go without further delay,but also to take the diamond necklace with him. Question: Why was the man invited into the manager's office? Answer: | OPTIONS:
- Because his handwriting was like a thief's.
- Because a thief had used the same name as his.
- Because he didn't sign his name correctly.
- Because his cheque was different from others.
A: Because a thief had used the same name as his.

Q: Read the following article and answer the question. Article: Welcome to the future. It's year 2050 and Scotland is now powered completely by"clean"energy. Homes have entire roofs made of solar materials, rooms are kept warm by wallpaper, and people go to and from work in electric and hydrogen( ) cars. Oil is still being found in the North Sea, but it's not now only used to keep aircraft flying. And a new 500---mile underwater link with Iceland has been built to catch heat from the hot springs. There's still a role for king coal--but _ are now environment---friendly. People will be able to import the electricity they need and export any excess they make through rooftop windmills . New technology will store electricity better and provide it on demand. Heat exchangers will provide heating and hot water. Harmful carbon dioxide waste is being piped offshore to St Fergus and from there into some of the remaining oil--producing fields to be stored safely without entering the atmosphere. Gas remains the preferred energy source of industry and is now shipped in liquid form. But hydrogen is imported through pipelines from France and from a geothermal plant in Iceland. Hydrogen--fuelled cars have become popular. Electric bikes are common in cities using the new urban two--wheel network. Electric vehicles have become common, and their performances have been improved because of the developments in electrical drive technology like high--temperature super conducting motors. Many people leave their vehicles in a giant park where they can be recharged from the national electrical system . Oilseed rape is widely grown to fuel some motors . Question: Which sources of energy play a more important role in people's daily life in the future ? Answer: | OPTIONS:
- Oil and coal
- Hydrogen and gas
- Electricity and gas
- Solar energy and wind
A: Solar energy and wind

Q: Read the following article and answer the question. Article: I got tired of living the life that everybody told me I "should" be living , so one day I decided to start living life on my own terms. Frustrated with my job, I came home, put on my shoes, and just started running. It felt so good to be free. That first day I ended up running 30 miles without stopping. Yes, I had rediscovered my old passion ( ) -- and it felt so good I set a goal to support myself and my family from my running alone. I trained hard every day. Since I wanted to be the best I could be, I knew I would have to set some clear goals for myself. A couple of my goals were: run a 135-mile ultra-marathon across Death Valley, win the Badwater Ultra-Marathon, and run a marathon to the South Pole. I had no idea how I was going to achieve these goals, but they certainly encouraged me to work hard. Today, I am really grateful to say that I have achieved all of them. Shortly after completing these goals, I set another goal: to run fifty marathons, in fifty states, in fifty days. Nobody had done anything like this before. To be honest, I was not quite sure if I could. But there was only one way to find out...so I just started training and preparing to give it my best try. I completed _ one year ago, and it felt great! But for me, life is not all about achieving goals. Sure, it feels good to succeed, but the greatest reward for me was learning more about myself and what I was able to do. Only by stepping out into the unknown and stretching ourselves can we really discover what our true potential is. Question: Why did the author decide to become a runner? Answer: | OPTIONS:
