Calls for Tsunami Alert System?
A tsunami is a series of huge waves caused by an undersea disturbance(干扰),such as an earthquake or volcano. The waves travel in all directions, like the ripples(波纹)caused by throwing a rock into a lake. Last year’s tsunami has made people realize the importance of tsunami early warning systems. The US National Oceanic and Atmospheric Administration has a system of buoys (that are called the Tsunami Real-Time Reporting System).There are six of these ?tsunami? detection systems placed around Pacific coastlines. The BPR recorders are used to detect slight changes in the overlying water pressure. They can detect wave as small as a centimeter above the sea level. This information is sent to a satellite via the buoy. The satellite then sends the data to the two warning centers in Alaska and Hawaii.?

China has recently been faced with serious issues of product safety. In Panama, it is said that medicine made with a poisonous chemical sickened some people. A Chinese company had identified it as diethylamide glycol ( [化]乙二醇), a low – cost substitute commonly used in automobile antifreeze(防冻剂).
Some countries have banned Chinese-made toothpaste containing diethylamide glycol. China has now told companies to discontinue its use, even though it says the toothpaste is safe. Another industrial chemical, melamine, was found in wheat flour used to make pet food in North America. Thousands of dogs and cats became sick.
The United States has restricted some imports of Chinese seafood because they contained banned substance. And questions have been raised about other products, including children’s toys covered with lead paint.
Chinese officials promised to provide the European Union, the biggest trading partner, with detailed reports on enforcement efforts against unsafe goods.
Meglena Kuneva, commissioner (理事) for consumer protection of the European Union said China should have kept its promise.
China recently closed three companies linked to the Panama and the pet food scare. And it dismissed the former head of its food and drug administration. He was found guilty of corruption (腐败) for approving unsafe drugs. This week, a conference of the State Council approved a proposed special measure on the supervision of food safety. The Xinhua News Agency said it calls for stronger controls over producers, greater responsibilities for government and more serious punishment for illegal activities.
But Chinese officials have accused some foreign media of overstating problems with goods made in China. They say food imports from the United States also fail inspection sometimes. Next Week, American and Chinese food safety officials are planning to hold 5 days of meetings in Beijing to discuss cooperation.
