Q: Read the following article and select the best answer. Article: Andrew Ritchie, inventor of the Brompton folding bicycle, once said that the perfect portable bike would be "like a magic carpet...You could fold it up and put it into your pocket or handbag". Then he paused: "But you'll always be limited by the size of the wheels. And so far no one has invented a folding wheel." It was a rare -- indeed unique -- occasion when I was able to put Ritchie right. A 19th-century inventor, William Henry James Grout, did in fact design a folding wheel. His bike, predictably named the Grout Portable, had a frame that split into two and a larger wheel that could be separated into four pieces. All the bits fitted into Grout's Wonderful Bag, a leather case. Grout's aim: to solve the problems of carrying a bike on a train. Now doesn't that sound familiar? Grout intended to find a way of making a bike small enough for train travel: his bike was a huge beast. And importantly, the design of early bicycles gave him an advantage: in Grout's day, tyres were solid, which made the business of splitting a wheel into four separate parts relatively simple. You couldn't do the same with a wheel fitted with a one-piece inflated tyre. So, in a 21st-century context, is the idea of the folding wheel dead? It is not. A British design engineer, Duncan Fitzsimons, has developed a wheel that can be squashed into something like a slender ellipse . Throughout, the tyre remains inflated. Will the young Fitzsimons's folding wheel make it into production? I haven't the foggiest idea. But his inventiveness shows two things. First, people have been saying for more than a century that bike design has reached its limit, except for gradual advances. It's as silly a concept now as it was 100 years ago: there's plenty still to go for. Second, it is in the field of folding bikes that we are seeing the most interesting inventions. You can buy a folding bike for less than PS1,000 that can be knocked down so small that it can be carried on a plane -- minus wheels, of course -- as hand baggage. Folding wheels would make... Question: We can learn from the text that Fitzsimons's invention _ . - kept the tyre as a whole piece - was made into production soon - left little room for improvement - changed our views on bag design
A: kept the tyre as a whole piece

Q: Read the following article and select the best answer. Article: How to eat healthfully can be especially complex for working women who often have neither the desire nor the time to cook for themselves (or for anyone else ).Registered dietitian Barbara Morrissey suggests that a few simple rules can help. "Go for nutrient-dense foods,"she suggests,"foods that contain a multiple of nutrients. For example,select whole wheat bread as a breakfast food,rather than coffee cake. Or drink orange juice rather than orange drink,which contains only a small percentage of real juice--the rest is largely colored sugar water. You just can't compare the value of these foods, the nutrient-dense ones are so superior,"she emphasizes. Morrissey believes that variety is not only the spice of life,it's the foundation of a healthful diet. Diets which are based on one or two foods are not only almost impossible to keep up the strength,they can be very harmful, she says, because nutrients aren't supplied in enough amounts or balance. According to Morrissey,trying to find a diet that can cure your illnesses,or make you superwoman is _ ." As women,many of us are too concerned with staying thin,"she says,and "we believe that vitamins are some kind of magic cure to replace food." "We need carbohydrates,protein and fat-they are like the wood in the fireplace. The vitamins and minerals are like the match,the spark,for the fuel,"she explains." We need them all,but in a very different proportions . _ ." Question: Orange juice is different from orange drink because _ . - it contains only a small percentage of real juice - it is natural,nutritious and prepared from real oranges - it is largely orange-colored sugar water - it produces nothing but calories
A: it is natural,nutritious and prepared from real oranges

Q: Read the following article and select the best answer. Article: The fighting against youth smoking since I took office I've done everything in my power to protect our children from harm. We've worked to make their streets and their schools safer, and to give them something positive to do after school before their parents get home. We've worked to teach our children that drugs are dangerous, illegal and wrong. Today, I want to talk to you about the historic opportunity we now have to protect our nation's children form an even more deadly threat: smoking. Smoking kills more people every day than AIDS, alcohol, car accidents, murders, suicides, drugs and fires combined. Nearly 90 percent of those smokers lit their first cigarette before they turned 18. Consider this: 3,000 children start to smoke every day illegally, and 1,000 of them will die sooner because of it. This is a national tragedy that every American should be honor-bound to help prevent. For more than five years we've worked to stop our children from smoking before they start, launching a nationwide campaign to educate them about the dangers of smoking, to reduce their access to tobacco products, and to severely restrict tobacco companies from advertising to young people. If we do these, we'll cut teen smoking by almost half over the next five years. That means if we act now, we have it in our power to stop 3 million children from smoking and to save a million lives as a result. Question: For more than five years what have they done to stop their children from smoking? - To educate them about the dangers of smoking - To reduce their access to tobacco products - To restrict tobacco companies from advertising to young people - All of the above
A: All of the above

Q: Read the following article and select the best answer. Article: When you get tense about something that happens in your life, you are experiencing stress. Too much stress can cause anger, depression and other related symptoms, which you need to seriously look into. The following are simple ways that can be used to deal with stress. Be Gentle with Yourself There are times when you are not fair to yourself. Often you are harder on yourself than you are of other people. If you can learn to accept yourself just the way you are, especially unconditionally, this would reduce the pressure you apply to yourself. Exercise Go for a walk. Go to the shops. You can join a local walk, swim or jog team. If you are tired out from doing housework and haven't left your workstation, have a stretch. Change your environment for an hour or so. Stop Comparing Yourself with Others Often you don't realize that a great deal of unhappiness is caused by constant comparisons you make. You says, "if only I had a big house like she was...", "if only my husband were as rich as hers..." The comparison is endless. The only comparison that counts is the comparison between where you were and where you are now . By all means, admire others, congratulate them and be proud of their achievements, but remind yourself that only you can decide the standard you want to set for yourself. Talk the Stress Out Sometimes it helps to share or talk about your stress to close friends or family members. The other person's active listening can help. Question: The passage is mainly about _ . - doing exercise is good for you health - how to deal with stress in life - comparing yourself with others is wrong - how to lead a happy life in daily life
A: how to deal with stress in life
