Quick News Review of the Week: May 8-14
Sino-Japanese talks
Beijing and Tokyo have agreed to hold talks later this month on natural gas exploration in the East China Sea. The two sides will soon set up a meeting between their foreign ministers in an attempt to thaw icy relations.
The agreement was reached last Tuesday, the third and final day of a Sino-Japanese strategic dialogue in Guiyang, capital of Southwest China's Guizhou Province.
Chinese Vice-Foreign Minister Dai Bingguo and his Japanese counterpart, Yachi Shotaro, headed the two delegations.
Retail growth
The Ministry of Commerce said last week that the country's retail sales rose by 16 percent year-on-year over the May Day holiday week, with larger retailers primarily driving growth.
Retail sales of consumer goods hit 278 billion yuan(US $34.7 billion) over the holiday period. The figure accounted for nearly half of the country's average monthly retail sales in the first quarter of this year.
Big chain enterprises used their larger sales networks and brand power to play a leading role in the "Golden Week" market, the ministry said.
Pyramid schemes
Chinese authorities have uncovered more than 1 billion yuan(US $125 million) in illegal pyramid scheme sales over the past 12 months, the Ministry of Public Security said last week.
Figures from the ministry reveal 516 cases involving l, 147 direct sales organizations. A total of 3,408 suspects were arrested.
Gao Feng, deputy director of the ministry's Economic Crime Investigation Bureau, said pyramid schemes had become a serious economic crime in China.
New fund
Bohai Industrial Investment Fund, the first fund launched by mainland enterprises to directly invest in other companies, will begin operations next month, Tianjin Mayor Dai Xianglong said last week.
"The fund's senior management team has been determined, so it's ready to start in June," Dai said.
The creation of the fund could lead to the establishment of similar organizations in China, which is welcome news for companies short on capital, analysts said.
Airport development
The central government said last week that China will spend more on airport development in the next five years than it has in the previous 15, opening up huge investment opportunities for overseas and domestic investors.
The Civil Aviation Administration of China(CAAC. the industry regulator, said 140 billion yuan(US $17.5 billion) has been earmarked(指定款项等的用途) for airport development from 2006 to 2010. Only 120 billion yuan(US $15 billion) was invested in the country's airports between 1990 and 2005. Spending will now focus on the development of 42 new airports, in addition to upgrades to existing infrastructure.
Dam completion
Construction of the giant Three Gorges Dam on the Yangtze River is scheduled to finish by May 20, marking the completion of the biggest part of the Three Gorges Hydropower Project.
Cao Guangjing, deputy general manager of China Yangtze River Three Gorges Project Development Corp, said last week the dam would be completed nine months ahead of schedule.
The dam, which is 2,309 metres long, 185 metres high and 15 metres wide, will be the world's largest. Approximately 16.1 million cubic metres of reinforced concrete bas been used on the project.
Port expansion
China's port and shipping facilities will be expanded to include two major new regions, the Ministry of Communications said last week.
Five new "port clusters" will be prioritized as part of a new development plan that will complement existing ports in Shanghai, Shenzhen and Tianjin.
Communications Minister Li Shenglin said some of the new port groups would be located on the mainland side of the Taiwan S

Renewable Energy Sources
Today petroleum (石油)provides around 40% of the world's energy needs, mostly fuelling automobiles. Coal is still used, mostly in power stations, to cover one-quarter of our energy needs, but it is the least efficient, unhealthiest and most environmentally damaging fossil fuel (矿物燃料). Natural gas reserves could fill some of the gap from oil, but reserves of that will not last into the 22nd century either. Most experts predict we will exhaust easily accessible reserves within 50 years. Less-polluting renewable energy sources offer a more practical long-term energy solution. "Renewable" refers to the fact that these resources are not used faster than they can be replaced.
Hydroelectric (水力发电的)power is now the most common form. of renewable energy, supplying around 20% of world electricity. China's Three Gorges Dam is the largest ever. At five times the size of the US's Hoover Dam, its 26 turbines (涡轮机)will generate the equivalent energy of 18 coal-fired power stations. It will satisfy 3% of China's entire electricity demand.
In 2003, the first commercial power station to use tidal (潮汐的)currents in the open sea opened in Norway. It is designed like windmill (风车), but others take the form. of turbines.
As prices fall, wind power has become the fastest growing type of electricity generation-quadrupling (翻两番)worldwide between 1999 and 2005. Modern wind farms consist of turbines that generate electricity. Though it will be more expensive, there is more than enough wind to provide the world's entire energy needs. Wind farms come in onshore and offshore forms. They can often end up at spots of natural beauty, and are often unpopular with residents. And turbines are not totally harmless-they can interfere with radar, alter climate and kill sea birds. Scotland is building Europe's largest wind farm, which will power 200, 000 homes. The UK's goal is to generate one-fifth of power from renewable sources, mainly wind, by 2020. But this may cause problems, because wind is unreliable.
According to the passage, which of the following is the most polluting energy resource？
A．Petroleum.
B．Coal.
C．Natural gas
D．Water.

Renewable Energy Sources
Today petroleum provides around 40% of the world"s energy needs， mostly fuelling automo- biles. Coal is still used， mostly in power stations， to cover one-quarter of our energy needs， but it isthe least efficient， unhealthiest and most environmentally damaging fossil fuel. Natural gas reservescould plug some of the gap from oil， but reserves of that will not last into the 22nd century either.
Most experts predict we will exhaust easily accessible reserves within 50 years. We could fastreach an energy crisis. We need to rapidly develop sustainable solutions to fuel our future. Less-polluting renewable energy sources offer a more practical long-term energy solution. They may ben-efit the world"s poor too. "Renewable" refers to the fact that these resources are not used fasterthan they can be replaced.
The Chinese and Romans used watermills over 2，000 years ago. But the first hydroelectricdam was built in England in 1870. Hydroelectric power is now the most common form. of renewableenergy， supplying around 20% of world electricity. China"s Three Gorges Dam， which has just beencompleted，is the largest ever. At five times the size of the US"s Hoover Dam， its 26 turbines willgenerate the equivalent energy of 18 coal-fired power stations. It will satisfy 3% of China"s entireelectricity demand. Surprisingly，some argue that hydroelectric dams significantly contribute green-house gases.
In 2003， the first commercial power station to harness tidal currents in the open sea opened inNorway. It is designed like windmill， but others take the form. of turbines.
As prices fall， wind power has become the fastest growing type of electricity generation——quadrupling worldwide between 1999 and 2005. Modern wind farms consist of turbines that gener-ate electricity. Though it will be more expensive， there is more than enough wind to provide theworld"s entire energy needs. Wind farms come in onshore and offshore forms. They can often endup at spots of natural beauty， and are often unpopular with residents. And turbines are not totallybenign——they caninterfere with radar and leave a significant ecological footprint， altering climateand killing sea birds. Migrating birds may have more luck avoiding them. Scotland is building Europe"s largest wind farm， which will power 200，000 homes. The UK"s goal is to generate one-fifth of power from renewable sources， mainly wind， by 2020. But this may cause problems， be-cause wind is unreliable.
What are the energy resources that are renewable according to the article？ 查看材料
A. Petroleum and coal.
B. Natural gas.
C. Wind and water.
D. A and B.
