In parts of Africa, the sky is filled with a dark cloud. But this is no rain cloud. It is a living cloud made of billions of locusts that are traveling across the continent eating everything in their path.
And in the battle to stop this disaster, a radio station in Senegal, West Africa, is offering listeners 50 kilograms of rice if www..comthey can catch and kill 50 kilograms of locusts. The radio station is in one of Senegal’s worst affected regions.
This is West Africa’s biggest locust disaster in 15 years, and it is moving east, causing huge damage to crops. As they move, they breed, and increase their number and will soon threaten Sudan in the northeast of Africa. Some say it could reach Asia.

Although leaders of 12 countries have agreed on a plan, it is not expected to be enough. “We are now treating 6,000 hectares per day with pesticide, but we need to treat 20,000 hectares per day in order to have any hope of controlling this disaster,” said Mohamed Abdallahi Ould Babah, director of locust control in Mauritania.
Requests are being made for international aid, which is the only way to limit the crisis, the UN’s Food and Agriculture Organization warned.

A senior United Nations Children’s Fund(UNICEF) official on May 29 praised China for its remarkable achievements in children’s welfare.
A. H. M. Farook, UNICEF’s operations area officer for China and Mongolia said that China “can be very satisfied to tell the whole world what can be done with limited resources to help its children to grow healthily and happily.”
China’s child population makes up one-fifth of the world’s total. “The reason behind the tremendous(巨大的) achievement is China’s long tradition of caring for children both at home and in society,” he said.
“What’s more is that Chinese people have always given special attention to children who are in special need.” The UN official made the remarks when addressing a group of 50 children and staff from the Beijing Children’s Welfare Home at the Shangri-la Hotel, Beijing.

The Beijing children’s Welfare Home, set up soon after New China was founded in 1949, has at present more than 400 children.
A leading official of the welfare institution said that the children live a happy life and that the agency spends 400—500 yuan a month for an average orphan. An average Chinese workers earned 440 yuan a month during the first quarter this year.
Gu Xiaojin, deputy secretary-general of the China Youth Development Foundation(CYDF), said people from all walks of life have contributed to the welfare of the Chinese children.
She said that CYDF set up the Project Hope in 1989, which calls on people across the country to donate money to help poor children to continue their schooling.
By the end of last year, she said, CYDF had collected nearly 700 million yuan in donations, which has helped the establishment of 2, 074 Hope primary schools and enabled more than 1. 25 million dropouts to return to school classrooms.
Three “Hope Stars” also attended the party. They were model teenagers chosen among students who are economically supported by the Project Hope to further their nine-year compulsory studies in the poverty-stricken regions. They will be torchbearers for the Chinese Team for the up coming Atlanta Olympic Games this year.

A dam is a man-made structure built across a river. Most dams are built to control a river’s water flow, improve navigation and control flooding. However, some dams are built to produce hydro-electric power.
Hydro-electric power is produced as water passes through a dam, and into a river below. The more water that passes through a dam, the more energy is produced. Once a dam is built, a man-made lake is created behind the dam.
Electricity is produced by a kind of equipment called a turbine(水轮机). Turbines contain metal coils(线圈) surrounded by magnets(磁铁). When the magnets move round rapidly over the metal coils, electricity is produced. Turbines are located inside dams. The falling water makes the magnets go around the coils.
Dams provide clean energy, but they can also harm the environment. Species that use rivers to reproduce are often hurt by dams. In the Northwest of the US, the population of fishes has dropped from 16 million to 2.5 million since hydro-electric plants were built on the Columbia River. Dams all over the world have hurt some species.
The highest dam in the Unites States is located near Oroville, California. The Oroville Dam towers 230 meters and is more than a mile wide. This dam was built in 1968, 22 years after the Hoover Dam. The Hoover Dam, on the Nevada-Arizona border controls the Colorado river. It is 221 meters high and has 2.6 million hectare-meters of water.
The highest dam in the world is the Nurek Dam on the Vakhsh River in Tadzikistan, a country in central Asia. This dam is 300 meters tall.
Which of the following statements is NOT true according to the passage?
A. Some dams are built for controlling a river’s water flow.
B. Hydro-electric power is usually produced through a dam.
C. Dams can offer energy and they are harmless to the environment.
D. Generally speaking, where there is a dam, there is a man-made lake.
The third paragraph mainly tells us _____.
A. how hydro-electric power is produced
B. What a turbine is and how it works
C. how the magnets and the metal coils work
D. how the falling water passes through a turbine
The dam which controls the Colorado river is ____.
A. the Oroville Dam B. the Hoover Dam C. the Nurek Dam D. the Vakhsh Dam
