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.

I am a professor of sports and exercise so I often deal with nervousness in my research with sports people. Actually, most people experience nervousness at some time or another.
If you are feeling anxious, my advice is to first find the cause or causes. Make s list of those things that are making you nervous and work out which ones you can do something about. Focus all of your efforts on managing the causes that you can control.
Most people cannot tell the difference between controllable(可控制的) and uncontrollable causes, so things they can’s control become a big reason for nervousness. Dealing with this is very important if people want to keep a healthy mind.
Simply try to accept the uncontrollable causes of nervousness. You might be worried about the weather on a big day, an accident or an attack on the train, or perhaps just things that other people are doing at work. The results may be very important but there is still no use worrying because you can’t control any of these things. Accept that you can’t control everything. Once you understand this, it becomes easier not to worry.
If a situation, such as swimming, is causing you to be anxious, try to face it as often as possible so that you can get used to it.
It can often help to think about yourself doing the thing that makes you nervous—then close your eyes and imagine it going well. Imagine how the flight or job interview is going to happen so that you can get used to it. This will help you understand that the thing you fear most is probably not going to happen.

Are you carrying too much on your back at school? You’re not alone. Back experts in the United States are worried that young students are having back and neck problems as a result of carrying too much in their backpacks (schoolbags)
“It hurts my back when I run,”said Oberlin Reyes, a student in Virginia. “It’s hard to go up the stairs with my backpack,because it’s too heavy,”
Oberlin was among students whose backpacks were weighed for a week in a recent study.
They had regular backpacks with two straps(带子)to carry them, but a number of students with heavy loads had switched to rolling backpacks (which have wheels and can roll on the ground).
Shirley Park, whose backpack weighed 10 kilograms,said she changed to a rolling backpack because she was starting to have back  pain.
How much is too much?Experts say students should carry no more than 10 to 15 percent of their own body weight.
A few students had one suggestion to lighten the load:less homework.
P.S.( 附)Doctor’s suggestion:
1 Lighten the load. Clean out binders(活页材料)and take home only the books you need that night.
2 Wide straps are better. They send out the weight over your shoulders more evenly(均匀)。 And be sure to wear both straps rather than hanging the pack over one shoulder.
3. Pack smart. The heavier things should be packed closed to the back.
4.Bend both knees when you pich up the pack ,and don’t just bend over  at the waist.(腰)
