    Today, we will talk about diet and weight loss. Exercise is important if you want to get in good shape. To have a perfect body, someone go to extremes to lose weight. 1.

    In the weight loss industry, there is never a lack of ideas about how to lose weight. Consider the “Sleeping Beauty diet,” where you sleep your way to weight loss. You cannot eat if you are sleeping, or so the theory goes.

    2. The tapeworm (绦虫) is said to help people lose weight by eating the food that is stored in their stomach. But first you have to be willing to eat the little worm. This may be more trouble than many people want.

    Strange, new diets and exercise programs arrive on the market every day. 3. The weight loss industry takes in billions of dollars each year, and it is growing.

    Experts say there is no single diet plan that works best for everyone. Many experts agree on one thing: you must use or burn off more calories than you take in to lose weight. When you eat more calories than your body needs, it stores that extra energy as fat.

    4. A pound of fat is equal to about 453 grams or 3,500 calories. To lose that fat in a week, you have to burn off at least that amount in calories or eat that much less.

    5. Eat fewer calories and increase physical activity so that you burn off more.

    A. Then there is the tapeworm diet.

    B. Calories are a measure of energy in food.

    C. But no plan has come out as a clear winner.

    D. The best thing to do is to combine both ideas.

    E. These lead to a big industry — weight loss industry.

    F. But experts say exercise alone is not enough if your goal is to lose weight.

    G. Each one promises to help people lose weight and get a beautiful body.

    Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach(菠菜) to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.

    Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.

    People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.

    Today, we know that the little iron there is in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.

    It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.

    1.A good title for this reading passage is______.

    A. The Truth about Spinach B. Popeye the Sailor

    C. A Mistake with Numbers D. Folic Acid Makes You Strong

    2.Why did many people eat spinach after they saw Popeye the Sailor?

    A. They thought Popeye was funny.

    B. They thought spinach made them strong.

    C. Spinach had a lot of iron.

    D. People liked folic acid.

    3.A research group told people that spinach______.

    A. made Popeye strong

    B. was a green vegetable

    C. had more iron than other green vegetables

    D. had less iron than other green vegetables

    4.The reading passage says that perhaps Popeye got his strength from______.

    A. iron B. exercise

    C. spinach D. folic acid

    There have always been a lot of commonly believed but false ideas about being fat and doing exercise. Some people believe that they can’t help putting on weight as they get older, while others hold that if they stop exercising, their muscles will turn into fat. Here are some more myths:

    No pain, no gain

    Wrong! Exercise is not meant to hurt. Indeed, pain is your body telling you something’s wrong, and continuing to exercise could lead to serious injury. You may experience mild discomfort as you begin to exercise regularly, but this is adapting to the positive changes in your lifestyle and the aches should disappear relatively quickly. If you don’t, rest and seek medical advice.

    1.What does the author think about being fat?

    B. People are fat because they consume too little energy.

    C. A diary of exercise can prevent people from becoming fat.

    B. By choosing simple exercise.

    C. By doing regular exercise.

    D. By sticking to（坚持）outdoor exercise.
