"But we just don't have the money to buy expensive diet foods and there isn't enough money to join a gym." Many people feel that way -- that a healthy diet and exercise plan is out of reach because of their high cost. Don't lose hope! We'll be looking at ways to make healthy choices without spending too much money. First you don't need to buy the expensive pre-prepared "diet foods." Back in the early 1970s when I started housekeeping, 90% of the food I bought was ingredients. Very few things were preprocessed . Now 90% of the food you find in the store is quick food. That's a bad thing. Quick foods like boxed "just add hamburger" meals have had the fiber removed to make them faster to prepare. Take a look at the label on that box. It often has low numbers listed under "fiber" because fiber takes longer to digest. If the low fiber meal is digested, the result is that your body begins to store fat. Besides, your body is short of nutrients . You will be driven to eat more to try to make up for the low quality of the food you are eating. And then there are the chemicals the producers add to the quick meals to make them palatable. If not, the stuff would taste like cardboard and you wouldn't enjoy it. However, these chemicals certainly aren't good for your health. What's the answer? Buy whole ingredients and give up the expensive, low nutrition, processed foods. Do the cooking yourself and you will have control over what is in your food -- and it will cost less, too. Question: The author suggests in the text that people should _ . - control the amount of food - eat more processed foods - cook food for themselves - choose cheap ingredients
cook food for themselves

Ques: Read the following article and select the best answer. Article: A back injury led Briton Rose Oliver to t'ai chi, which led her to her husband and then took both of them to China. But three years after moving to Shanghai to pursue their dream, Oliver's husband died, leaving her alone to follow their shared passion for t'ai chi. Twenty years ago, Oliver's back injury ruined her childhood dream of becoming a ballet dancer. But the injury did lead her to t'ai chi, a martial art typically practiced in slow motion. Her initial hope was to improve her health. She later married her instructor, Rey Nelson, and founded a school with him, teaching the martial art to more than 10, 000 students over eight years. The 49-year-old recalls the injury that left her bedridden for six months when she was 21 years old and with constant pain for decades. "I was active and could not bear resting in bed," she recalls."But the soft tissue injuries were hard to heal. I thought I had to find some way to recover my health." Oliver saw a poster for a t'ai chi class and decided to try the"mysterious exotic sport". She was struck by the beautiful movements and the"nice, patient instructor -- Nelson". The couple later opened a t'ai chi school in the United Kingdom that attracted thousands of people. But they found themselves in a bottleneck. "It was not enough for us to improve ourselves when we just learned from t'ai chi masters for two or four weeks a year,"she says. So the couple moved to Shanghai. They taught English in universities and happily learned t'ai chi under various masters. After years of practice, Oliver found her occasional backaches had disappeared. In 2003, her husband's death brought her much pain. She thought of giving up, but considering the career in which her husband took pride, she stuck to it. She says her t'ai chi"family"-- the masters and students -- also provided a great support network. Her then tutor was Dong Bing and Dong died in 2009 at the age of 88. She speaks of their first meeting:"I had been told that his skill was of a very high level and for some reason I had a... Question: What made Oliver keep playing t'ai chi? - Her love for t'ai chi. - Her tutor Dong Bing. - Her fellow's encouragement. - Nelson's pride in t'ai chi.
Ans: Nelson's pride in t'ai chi.

Question: Read the following article and select the best answer. Article: Parents whose children think the latest Nike or Adidas shoes may be better than buying old-fashioned plimsolls because they encourage a healthier style of running, researchers said. Big companies, like Nike and Adidas, make millions of dollars from selling highly-cushioned shoes both as fashion and sports shoes. The researchers warn that wearing such shoes from an early age can make it difficult to run in a healthy way. Once we have grown used to running in this kind of shoes, it is very difficult to change our technique, even if we remove our shoes, it can raise the risk of injury. Children should be encouraged to wear shoes with thin soles such as plimsolls from a young age to help them develop a natural "barefoot" running style, experts said. Dr Mick Wilknson, who did the research, told the British Science Festival in Newcastle, "If I would advise someone on what to give their child, I would say don't go and buy them expensive Adidas or Nike, just get them a pair of flexible, flat shoes. Give them basic foot-ware, nothing fancy, nothing particularly cushioned." Running in flat shoes, barefoot, encourages the runner to use the front of their foot which is a better technique for running, especially long distances as the human was designed to do. Around the world, and in particular in the US, running barefoot is becoming more and more popular with many long distance runners training without shoes. Dr Mick Wilknson believes that training and running barefoot or in flat running shoes can help reduce injuries to runners, he said: "Injury rates in running have not changed since the 1970s, despite claims of improvements in running shoes. That has led some to conclude that barefoot running is better." Question: Why are people advised to wear plimsolls? - They have a new fashion - They have better quality. - They are healthier - They are cheaper.
Answer:
They are healthier
