Today, however, we needn't worry about feeling pain during the operation. The sick person falls into a kind
of sleep, and when he awakes, the operation is finished. But these happy conditions are fairly new. It is not
many years since a man who had to have operation felt all its pain.
Long ago, operation had usually to be done while the sick man could feel everything. The sick man had to
be held down on a table by force while the doctors did their best for him. He could feel all the pain if his leg or
arm was being cut off, and his fearful cries filled the room and the hearts of those who watched.
Soon after 1770, Josept Priestley discovered a gas which is now called "laughing gas". Laughing gas
became known in America. Young men and women went to parties to try it. Most of them spent their time
laughing, but one man at a party, Horace Wells, noticed that people didn't seem to feel pain when they were
using this gas. He decided to make an experiment on himself. He asked a friend to help him.
Wells took some of the gas, and his friend pulled out one of Well's teeth. Wells felt no pain at all. As he
didn't know enough about laughing gas, he gave a man less gas than he should have. The man cried out with
pain when his tooth was being pulled out.
Wells tried again, but this time he gave too much of the gas, and the man died. Wells never forgot this
terrible event.

With an obese (very fat) or overweight population of 66% percent of adults, teaching your kids healthy eating habits is one of the most important things you can do for them as a parent. Most parents and children claim that breakfast is part of their everyday routines. But for many more than you might think, it's not. Children who eat breakfast have higher math grades, have improved reading scores and basically perform better in school. They also tend to have healthier bodies in general, with better-controlled weight levels. When you take them to the grocery store with you, it's doubtless that your children will request the most sugar-filled, fat-injected products on the shelf. But these are not the ones to have in your home-you should avoid buying them at all. Be sure your kids have healthy snacks. Yes, kids like white bread. But any kid can get used to the taste of whole grains. It just takes a little practice. Look for white bread, and add other whole grains into their diet. Start toasting their sandwiches. When it's toasted, it'll be that much harder for them to tell the difference in taste. It's simple, it's true, and it's something you already know: kids who get plenty of exercise are healthier kids. Set limits on the amount of time your child may spend in front of the television or computer screen. Sign them up for plenty of sports and outdoor activities. And best of all, get involved in sports and exercise with them. One of the best things you can do to establish healthy eating habits in your kids is to have them yourself. You can tell your kids every day to eat healthy foods, but if you don't do the same thing yourself, the lesson will never stick.

| Write NO MORE THAN THREE WORDS for each answer. Tomatoes are the world's most popular fruit rich in nutrition like Vitamin A, C, fibre and lycopene (番茄红素). Researchers have found that consuming lycopene helps in preventing cancer. Tomato also helps in keeping the skin healthy and young by protecting from harmful rays. Since lycopene is present in the cellular wall of tomato, it is better to consume cooked tomato to have higher concentration of lycopene. So tomatoes are a wonderful fruit. Then how to grow tomatoes? First, there should be regular and even watering in the fields where tomatoes grow. You can also add fertilizer to have better results. Plant the tomato plants with enough space(for example 2 to 3 inch space)between each other to lessen spreading of disease and pests and help the fruits get enough sunlight. Provide support like pole when the plants grow up to prevent from disease and to increase the crop product. In order to make your tomatoes grow well, you should take some useful tips. For example, choose variety based on the season and soil type that you are growing. Planting site should have enough sunlight to have more fruits. Prune(修剪)the tomato plants if necessary to maintain a manageable size. Check tomato plants regularly for any kind of pests and diseases. To people's regret, tomatoes possibly suffer from some diseases during their growth. So you must try your best to prevent them. Soil should be free from debris(残骸)of earlier plant remains and should be treated first before tomato plantation like solarizing(晒) to prevent from pests. It is always better to choose resistant plant varieties and follow crop rotation(轮作)as far as possible.
