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.

Experts say the great damage to crops in areas already suffering from food shortages and war could cause many people to go hungry. Governments in the region are not well equipped to fight the pest.

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.

1. The purpose of offering people rice for catching locusts in Senegal is ________.

A. to get more people to eat rice so as to leave less for locusts

B. to get more people involved in the war on the locusts

C. to prevent more people from starvation

D. to get more people to listen to the radio report on locusts

2. Which of the following is not the reason for West Africans going hungry?

A. Locust disaster causes the great damage to crops.

B. Food supply is far from the need of the people.

C. These regions are affected by the war.

D. Governments are unwilling to fight the pest.

3. It can be concluded that, in order to end the locust disaster, ________.

A. leaders of 12 countries in West Africa should call on their people to take action

B. insects experts should be sent to these regions

C. other countries outside Africa should keep close watch on their own lands

D. Help from all over the world is in urgent demand

4. What does the passage mainly talk about?

A. Food shortage in Africa.              B. International aid to Africa.

C. The insects attack on Africa.          D. Terrible storm in Africa.

IS THERE LIFE ON EARTH?

There was great excitement on the planet of Venus(金星) this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.?

The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20 000 light years ago).Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility(可行性) of a manned flying saucer(飛碟) landing on Earth.A press conference was held at the Venus Institute of Technology.?

“We have come to the conclusion,based on last week's satellite landing,” Pro. Zog said,“that there is no life on the Earth.”?

“How do you know this?” the science reporter of the Venus Evening Star asked. ?

“For one thing, Earth's surface in the area of Manhattan is composed of solid concrete(混凝土)and nothing can grow there. For another, the atmosphere is filled with carbon monoxide(一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.”?

“What does this mean as far as our flying saucer program is concerned?”?

“We shall have to take our own oxygen with us, which means a much heavier flying saucer than we originally planned. ”

“Are there any other hazards that you discovered in your studies?”?

“Take a look at this photo. You see this dark cloud floating over the surface of Earth? We call this the Consolidated Edison Belt. We don't know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there.”?

“If what you say is true, won't this set back the flying saucer program several years?”?

“Yes, but we shall proceed as soon as the Grubstart gives us the added funds.”?

“Prof. Zog, why are we spending billions and billions of zilches to land a flying saucer on Earth when there is no life there?”?

“Because if we Venusians can learn to breathe in an Earth atmosphere, then we can live anywhere.”

During the week of great excitement the Venusian scientists succeeded in getting important information on whether they can_______.

A. land a satellite with Venus astronauts on Earth

B. make a first?rate flying saucer?

C. get a Earth Being to Venus

D. direct a flying saucer into Manhattan?

According to Prof.Zog,the Venusians will have to take their own oxygen with them when they carry out their flying saucer program because_______.?

A. they need it on their way to the planet of Earth?

B. the Earth's atmosphere is filled with deadly gases?

C. oxygen is far from enough in the area of Manhattan where the saucer is to land?

D. there is no air on the planet of Earth?

The “dark black cloud” on the photograph refers to_______.?

A. the polluted air floating over the surface of Earth?

B. the mass of tiny drops of water floating above Earth?

C. the things that are unknown to everybody?

D. the dark clouds gathering before a storm breaks?

The author wishes to call our attention to the fact_______.?

A. that modern man has polluted his environment to such an extent that he might destroy himself if he went on like this?

B. that there is no point in spending billions and billions of zilches to land a flying saucer on Earth?
