Parents and doctors have the same worry over especially low birthweight newborns. 【小题1】 A trend (趋势) has therefore developed to make special formulas (配方) of extra nutrients and protein-rich foods for these tiny babies. Unfortunately, a British study has found that this practice could have negative (负面的) long-term effects, such as high blood pressure in adulthood.

Between 1993 and 1995, Atul Singhal of the Institute of Child Health and his colleagues researched 299 full-term newborns, each of whom weighed very little for their age. The babies’ moms had decided not to breastfeed (用母乳喂养).

【小题2】 The rest received a formula with more nutrients and 28 percent more protein than the standard formula. The growth of all of these children was compared to that of 175 similarly low birthweight babies whose mothers had chosen to breastfeed their children for their first 9 months. 【小题3】 They found 83 babies from the normal-formula group, 70 babies from the extra-formula group, and 95 babies from the breast fed group.

【小题4】 According to the latest data, children who had received the extra formula had significantly higher blood pressures than those in the other two groups.

No matter how big a child is at birth, he or she will probably reach the same adult height no matter how quickly the baby grows. But reaching one’s adult size at a slow-to-moderate speed may have a lot of benefits, as Singhal says. 【小题5】

Almost every day, we discuss the topic of health, especially for kids. But what is health? “Health” means eating well, getting enough exercise, and having a healthy weight. Let’s read the following rules. They can help you stay healthy.

1. Eat a variety of foods, especially fruit and vegetables. We all know that eating fruit and vegetables can help us stay healthy, but many of us only eat our favorite foods. Remember that we can only get the nutrition we need by eating different kinds of food, especially fruit and vegetables.

2. Drink water and milk most often. Everyone knows that water is important. Besides that, kids need plenty of calcium (钙) to grow strong bones, and milk has a lot of it. Every day, you should drink at least three cups of milk (1300 milligrams of calcium), when you are 9 years old or older. You should also try to have less sugary drinks, like soda and coca. They include a lot of sugar. Sugar just includes calories, not important nutrition.

3. Listen to your body. When you are eating, notice how your body feels. When your stomach feels comfortably full, stop eating. Eating too much makes you feel uncomfortable. If you do it too often, it can make you unhealthy and fat.

4. Limit screen time. What’s screen time? It’s the amount of time you spend watching TV, movies, and playing computer games. The more time you spend on these sitting-down activities, the less time you spend playing sports, like basketball, and doing other activities like bike riding and swimming. Try to spend no more than 2 hours a day on screen time.

Jane loved sweets(甜食). She liked to have some after breakfast, lunch and even supper. Sometimes she would have candies and an ice-cream, and sometimes she would even have a large piece of cake.

One day, Jane’s friend, Pat, asked her why she loved eating sweets so much and told her it was bad for her to eat so many sweets. Then Jane started to think that maybe she was eating too many sweets. So she made a plan to stop eating all sweets for one week. When she told the idea to her parents, they were pleased with that because they also thought eating too many sweets was bad for Jane’s health.

In the first few days, it was difficult for Jane and she felt terrible. Pat told her that when the week was over, she would be able to have sweets again as a prize for her hard work. By the fourth day, Jane waned to eat sweets so much, but she didn’t give up (放弃). So she tried to eat more healthy food like vegetables and fruit. They were good, but they were not as good as sweets to Jane. By the sixth day, Jane felt a little better. Then the last day came. That night Jane’s mom and dad made her an ice-cream. It was delicious. The most important thing was that Jane would have a healthier eating habit.
