MSG(monosodium glutamate谷氨酸单钠) 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 taste and color. It is used in foods around the world such as cakes, bread, frozen meat, 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 . 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 result 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 harmful food additives have been added to the food.

    To protect people's health, our governments, from central to local, are taking action to stop factories producing harmful food additives.

Hi, everybody. Here we're in front of the South Gate. Go straight on, and you'll find the Panda House. Pandas are cute. They like to eat bamboo and lie down all day long. Every year, lots of visitors come here to see them. 

Walk along the road. To the north of the Panda House, you'll find the lions. Lions are the kings of the animal world. Remember that they're dangerous. Never go near them.

Mars （火星） is a planet and is the 4^th closest planet to the Sun.The distances from the Sun to Mars is more than 141 million miles.Mars is the largest planet in the solar system（太阳系），which makes Mars the 2^nd smallest planet in the solar system.Mars is one of the four planets in the solar system that is a rocky planet.These rocky planets are called "Terrestrial（类地的） Planets".

It's not know when Mars was found and by whom as Mars has been known for a very long time，and one of the planets that can be seen from the Earth without a telescope（望远镜）.

Mars's orbit轨道） around the Sun is the 4^th fastest orbit of all the solar system planets.Mars is red in colour and is very cold.Not the coldest of planets in the solar system but very cold all the same.The temperature on Mars is on average 80 degrees，and can get a lot colder at times.

At times in the summer near the Mars the temperature can reach 70 degrees.You may think it's warm enough to live；however，the atmosphere（大气层）₂ over 95%.Mars orbits the Sun in 687 days，which means 1 Earth year on Mars is 687 days.
