Experts(专家)say that students usually need eight to ten hours’ sleep at night, but most Chinese students do not get enough sleep. Some Chinese parents are usually glad to see their children studying late. They will think their children work very hard, but not all parents are happy about this. Once a mother told us that every morning her boy who was 10 years old put up one finger(手指) with his eyes still closed, begging(请求)for one more minute to sleep. Like thousands of students “early bir ds” in China, he has to get up before six every morning.

A report shows that without a good night’s sleep, students seem to be weaker than they should be. Many students have fallen asleep during class at one t ime or another. Too much homework is not the only reason why students stay up late. Some watch TV or play the computer games late into the night.

Experts have ever said that the students should develop good study habits. So some clever students never study late, they are able to work well in class.

MSG (monosodium glutamate) is a food additive (食品添加剂), which has been widely used by many food factories all over the world since it appeared first in Japan in 1909.

MSG is a substance that is added to some food to improve its original (原先的) taste and colour. It is used in foods around the world such as cakes, bread, frozen meats, fish and vegetables. In the beginning, people thought MSG was safe just like salt and sugar. However, in 1968 some people reported they seemed to have bad reactions (反应) to MSG after having had a meal at a restaurant. They included headaches and quick heartbeat (心跳). It was also reported that MSG excited a person's brain and caused his death in Japan. Scientists think that MSG may lead to many neurological disorders (神经紊乱). In mice studies done by a university, the evidence showed the mice didn’t want to eat the food including MSG.

Today many food companies “hide” MSG on food labels (标签) by using different names. If you see “natural flavorings”, “hydrolyzed protein” and “spices” in a food label, you are probably seeing a hidden way to “report” MSG in a food label. Every time we have a meal in a restaurant, we always feel the food very delicious to taste, but sometimes it is dangerous for our health because some poisonous food additives have been added to the food.

To protect people’s health, our governments, from central to local, are taking actions to stop factories producing poisonous food additives.
