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 color. 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 (调味品) ”,“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 （有毒的）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.

Last weekend my father, my mother, my sister and I went to summer camp. We went to Mount Ermei. It was a very sunny but windy day. We got to the foot of the mountain by bus. In the middle of the mountain there was a clean and clear river. I washed my face with the water. It was a little warm. There were some fishes in the river, too. In the mountain there were many beautiful flowers. At noon, lots of people got together, and they were very friendly. We had lunch in the mountain. The food was very nice, and we liked it very much. After lunch, we went on our trip. Finally we got to the top of the mountain. From there we could see everything below because of the fine weather. I felt like I was flying in the sky. We had a wonderful time.

What do we do when we go camping? First, we make a plan. We take food, clothing, a knife, and things for cooking and eating. We take things to keep us away from insects and the sun.
Then we put everything into the car and we drive to the woods. We look for a place for campers(露营者) and we look for a good place for our tent(帐篷). The place should have a lot of moving air. This will keep some insects away. High land with water on both sides of it is good. Then we put up our tent. We put everything into the tent, and we are ready for fun. We can swim in the lake, walk in the woods, climb a mountain, row a boat, or go fishing.
In the evening we come back to the tent, and we build a big fire because it can keep the insects away. We sit around the fire and talk. We may tell interesting stories or we may sing songs.
