China has input several billion yuan of money to stop the dirty water waste on the upper and middle area of the Pearl River from polluting the lower reaches of the river, especially the Macao Spe­cial Administrative Region．

The Guangxi Zhuang Autonomous Region in the upper and middle reaches of the Pearl River has been rapidly urbanized（城市化）and industrialized in recent years, leading to a rise in the amount of urban rubbish to the damage of the land, rivers and atmosphere．

Refuse dumps and special plants in most cities treat rubbish to make it harmless, with 5,800 tons of wastes being burnt, buried or made into fertilizers on a daily basis．

He Suping, a woman engineer with the water re­sources department in Guangxi said, it is imperative for the autonomous region to treat sewage wastes to protect the area’s Karst terrain（喀斯特地形）and rain water which brings contact between groundwater and surface water, making groundwater more easily polluted．

The Xijiang River, a branch of the Pearl River which runs from Guangxi to neighboring Guangdong Province, provides fresh water for a number of river­side cities such as Macao, Zhuhai, Zhongshan and Zhaoqing, so Guangxi must begin to treat rubbish quickly to protect the water sources, said Liu Chen, a senior engineer with the Ministry of Water Resources．

The government 2001—2006 plan to spend bil­lions of yuan to turn wastes harmless has been mainly provided by national debt payments and overseas in­vestment．So far wastes treatment projects have re­ceived a total of 400 million yuan（48 million US dol­lars）from national debts and 60 million yuan（7．22 million US dollars）from overseas loans（贷款）．

1.The main idea of the passage is __________

A．A large number of waterways have been polluted in China up to now．

Planting trees around poultry farms can improve air and water quality -- and relations with neighbors. Research has shown that just three rows of trees near poultry houses can reduce the release of dust and ammonia(氨). They can also reduce the strong smell of ammonia gas.

The trees take dust, ammonia and odors in their leaves. They also provide shade from the sun, so they reduce cooling costs in summer. And they act as a windbreak, so they reduce heating costs in winter. Trees can also improve water quality around farms by removing pollutions from soil and groundwater.

Several years ago, people were objecting to the odor of poultry farms on the Delmarva Peninsula in the eastern United State s. Delmarva is where the states of Delaware, Maryland and Virginia come together. Two thousand farms there can each house an average of seventy-five thousand chickens.

Traditionally the farms used windows to provide fresh air in the chicken houses. Farmers rarely planted trees or tall crops around the buildings, so there would be no barrier to the airflow. But then farms began to use new ventilation systems. Instead of windows, the new systems used tunnel fans to circulate air. The fans directed airflow from the poultry houses toward the homes of neighbors.

Researchers began dealing with the problem in two thousand. They found that over a period of six years, planting three rows of trees reduced total dust and ammonia by more than half. And they found that smells were reduced by eighteen percent.

Farmers may think trees will take too long to grow and be effective. But some trees can grow quickly. At least one-third of the Delmarva farms have planted trees, technically known as vegetative environmental buffers. The idea offers a way to cut pollution, save money and energy, and make the neighbors happy.

1.The second paragraph mainly tells us ______.

2.The word “odor” in paragraph 3 means ______.

3.The farms on the Delmarva Peninsula used to use ______ in chicken houses to provide fresh air.

4.It can be learned from the last two paragraphs that ______.
