¡¾ÌâÄ¿¡¿Holding doors open, picking up rubbish, thanking people ¡­ these acts of kindness seem very small. But students at Tibbetts Middle School know that it¡¯s the small acts that make the world a better place.

Eighth-graders from New Mexico, US, took part in the Random (ËæÒâ) Acts of Kindness Week from Feb 10 to 14. During the week, they tried their best to do kind things for others, or for the environment.

Celeste Murray, an English teacher at the school, started the activity. ¡°I believe the world is changed by little things,¡± she told the local newspaper. Over the week, Murray said she has seen changes in her class. Previously, she asked her students to push the chairs in after class. Now, the students do it by themselves. ¡°The teachers will have less work,¡± said Elisea Castaneda, one of Murray¡¯s students.

Jordin Marshall, another eighth-grader, spent the week giving out praise (ÔÞÑï). ¡°It makes that person¡¯s day (ʹÄǸöÈË¿ªÐÄ),¡± she said. ¡°Besides helping others, the activity made students feel that they can make a difference,¡± Murray said.

¡¾ÌâÄ¿¡¿MSG (monosodium glutamate) is a food additive (ʳƷÌí¼Ó¼Á), 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 (Ô­ÏȵÄ) 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 (·´Ó¦) to MSG after having had a meal at a restaurant. They included headaches and quick heartbeat (ÐÄÌø). 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 (Éñ¾­ÎÉÂÒ). 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 (±êÇ©) 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.

A. you must eat the food in a hidden way

B. the food label must be hidden

C. MSG is probably added to the food

D. you must report the food to your parents
