Translate the text into Chinese. 1. Many people want to getand keep fit. Their intention is good, but the methods they use sometimes arenot. Over the years, directions like“eat less to lose weight” have been passed around as good advice. But infact, such fitness methods are unhealthy — and even dangerous. Unfortunately, many people want to loseweight so badly that they will believe any advice — good or bad. Here arefive of the most common myths about getting and keeping fit. 2“If I just eat less, I will lose weight.” Many people only focus on the amount of food they take in each day. They don’t pay attention to what they’reeating. So they may be eating less, but they’re not eating healthily. Be sure to eat a good balance of differentfoods, including vegetables, fruits, meat, milk, and bread or rice. What you eat is just as important as howmuch you eat. 3 “Running is allthe exercise I need to lose weight.” You need aerobic exercise to burn off yourextra fat. But that alone doesn’t help you get and keep fit. You mustalso lift weights to build muscles. You need both to get the most effectiveresults. 4 “If I buildmuscles, I will gain weight.” This is true. Muscle is denser than fat, sothe same amount weighs more. But muscle also takes up less space. When youreplace fat with muscle, you will look thinner and better. 5“The miracle diets on TV will help me lose weight.” These ads promise a miracle solution forlosing weight, but usually the products don’t live up to their promises andcan even be dangerous. Don’t waste your money on them. 6.“Some fancy exercise machine burns more calories than any other exercise.”People are often confused about the magical effects of these exercise machines.Don’t be fooled by this stuff. Fat burning is directly related to the amount ofeffort an activity requires. In general, the more difficult it feels, the more calories you burn. Nomatter how fancy or expensive the equipment is, the harder you work the betterit is for your body shaping. 7. What is the bestway to get and keep fit? Eat healthily and have a good balance of aerobic andmuscle building exercises. Make yourhealthy lifestyle last for a whole lifetime, not just for a short while.
