China Calls for Unified International Rules Against Internet Crime
Cyber security has always been a serious issue as the Internet industry is ever growing. Nowadays, people can easily connect to the Internet with a simple click of a mouse. But the global network can be easily destroyed by a single leak. The world is facing a difficult situation in keeping web security.
Currently, there are no unified international rules for maintaining Internet security. China has called for unified international rules against Internet crime. Last year China and some other countries handed in a draft Code of Conduct on Information Security to the UN.
World leaders and experts discussed the possible Internet threats facing the world. They agreed that the only way to deal with Internet security threats was to trust each other and strengthen cooperation. The threats cannot be solved by any one country alone. And for these reasons, countries would have a greater chance of trusting each other in dealing with such threats.
Though great efforts were made to issue common regulations for the Internet, few results have been achieved yet. There's still a long way to go for unified global Internet security rules and regulations.

第9题
听力原文：M: Doctor Thomas？ This is Keith Bradley from The Daily News. I'd like to ask you some questions about the new official standard weight that you purchased.
W: I'd be happy to help you. What would you like to know？
M: First of all, how is the standard weight used？
W: Well, the people in our department use it to check the scales all over the country. The Department of Weights and Measures—we're a government agency—it's our responsibility to see that all the scales measure a kilogram accurately. So this is the weight we use to adjust the scales.
M: How did you check the scales before？
W: We have an old standard weight that we used to use. It had to be replaced because it was imprecise. You see, it was made of poor quality metal that was too porous—it absorbed too much moisture.
M: Oh, so when the weather was humid, it weighed more. And when it was dry, it weighed less.
W: Exactly. And that variation can affect the standards of the whole country. So our department had the new weight made out of higher quality metal.
M: How much did it cost？
W: About forty-five thousand dollars.
M: Forty-five thousand dollars! For a one kilogram weight! That's more expensive than gold. Is it really worth that much？
W: I'm sure it is. Industries depend on our government agency to monitor the accuracy of scales, so that when they buy and sell their products there's one standard. Think of the drug industry, for example: those companies rely on high accuracy scales to manufacture and package medicine.
