Parents and doctors have the same worry over especially low birthweight newborns.
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).
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.
A.The results were quite surprising. |
B.These babies have very little energy because they are so small. |
C.His advice to parents: Be patient. Don’t rush a child’s growth. |
D.Half of these children were given a normal infant (幼儿) formula for 9 months. |
E.Six to eight years later, the researchers gave the children a series of measurements and tests. |

【推荐2】I am a boy. I am fourteen years old. I think eating well can help us study (学习) well. Here is something we can do.
Have a good breakfast.
We can get up at 7:00 every morning and have a good breakfast at home. If we have no time, we can have an egg, some milk and an apple on our way to school, too.
Eat a lot of food with calcium (钙).
We need much calcium. We can drink some milk every day. We can have some green vegetables to get calcium, too.

【推荐1】How good are you at remembering what you’ve learned at school? It is not an easy process for all. No one’s memory is perfect. Even the most intelligent people forget things.
The brain has short-term memory and long-term memory. When we learn something new, it stays in our memory for around 20 to 30 seconds. This is our short-term memory.
So one secret of remembering is to change short-term memory into long-term memory.
However, this is not always the best way to memorize things. Forgetting things that are not important helps our brain to remember things that are useful.
If you are interested in improving your memory, there are lots of simple things you can do, including eating healthily, sleeping well and exercising daily.
A.Besides, it’s also important to challenge your brain. |
B.It can hold a small amount of information. |
C.No one knows exactly how this happens. |
D.This does not mean a person has a bad memory. |
E.Our brain is always “cleaning out”useless information to make room for something more useful. |
【推荐2】Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back. Plants certainly cannot run away. But plants can protect themselves by using physical or chemical means.
Some plants have physical ways to keep animals away. For example, the leaves of the holly plant have sharp spines (刺) that discourage grass-eating animals. Its lower leaves have more spines than upper leaves. This is because the lower leaves are easier for most animals to reach. Oak trees have thick and hard leaves that are difficult for animals to eat. Some grasses may have a sandy material and eating such grasses wears down the animals’ teeth.
Many plants also have chemical ways to protect themselves. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar (毛虫) bites a tobacco(烟草) leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine(尼古丁). The higher levels of nicotine discourage the caterpillar from eating it. A single experience with this kind of plant will teach an animal to stay away from it in the future.
