Parts of Africa are covered by a dark cloud. But this is no rain cloud. It is a living cloud made of billions of locusts(蝗虫) that are travelling across the continent eating everything in their path.

And now in the battle to stop this disaster, a radio station in Senegal, West Africa, is offering listeners 50 kilograms of rice if they can catch and kill 50 kilograms of locusts. “We think this idea will get more people to take part in the war on the locusts,” said Abdoulaye Ba, from Sud-FM, a radio station in one of Senegal’s worst affected areas.

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 produce young and increase their number and will soon threaten(威胁) Sudan in the northeast of Africa. Some say it could reach Asia.

Experts say the harmful effect on crops in areas already suffering from food shortage and war could cause many people to go hungry. Governments in the areas 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(公顷) per day with pesticide(杀虫剂), 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 disaster,” the Food and Agriculture Organisation of the United Nations warned.

A.showed the relationship between rain and the locusts
B.suggested the great damage locusts have caused in the world
C.warned that locusts would sweep the continent like rain clouds

2. What is the passage mainly about?
A.Africans united effort in fighting a disaster.
B.The difficulty in controlling locusts.
C.How locusts caused great damage to West Africa.
D.A struggle to fight against a disaster brought by locusts in West Africa.
3. The locust disaster _________.
A.would be even more serious in Asia
B.is out of control
C.affected only the warning areas
D.cannot be stopped unless twice as much pesticide is provided for the affected areas
4. Which of the following is NOT TRUE according to the passage?

B.Senegal is to the west of Sudan.

【推荐1】When the tornado (龙卷风) passed, Lewis returned to her house after that awful night, and the Bible was the first thing she looked for. She had bought it 35 years earlier, at the start of her marriage. Like many folks, she’d used it to preserve the family’s history: decades-old photos, newspaper obituaries (讣告) of loved ones, a handkerchief from her great-grandmother, even a piece of a scarf her uncle bad brought back from the Korean War.

The Bible was not where she d last seen it, on top of an antique dresser in her bedroom. The only thing left was the solid pieces of marble that had been on the top of the furniture. After an hour of searching, one of the volunteers ran up to her and found the bible while clearing through ruins. She had tears streaming down her cheeks. It had flown about ten feet from the dresser. Surprisingly, while many books had been destroyed beyond recognition, the Bible was still intact, even though it had sat in the rain for days. “It was a miracle,” says Lewis.

A few of the Bible’s treasures did go missing. Yet ever so slowly, they, too, began reappearing in Lewis’s life. Days after the Bible was found, volunteers discovered one of the newspaper obituaries outside the home. Two weeks later, a neighbor found another newspaper clipping (剪辑) by her house. “It was a shock,” say Lewis.

Now the Bible already has its well-deserved place of honor, on the dresser. She knows that while every good book tells stories of disastrous weather and unlikely survival, this one actually lived it.

1. Why was the Bible the first thing to look for?
A.It is a book telling good stories.
B.It was a valuable gift for her marriage.
C.It records her family’s trees and history.
D.It keeps things recalling family’s stories.
2. What does the underlined word “intact” probably mean?
A.UnfoldedB.New
C.UndamagedD.fragile
3. What is the best title for tie text?
A.The Bible Beats a Tornado.
B.The Bible Blesses Lewis’ Family
C.Antique Treasures Are Never Gone.
D.Family Treasures Are Along With Us.

文章大意:本文是一篇说明文。文章主要介绍了飓风的预警和等级。

【推荐2】The National Hurricane Centre, lying in Miami, Florida, gives watches and warnings before hurricanes come near the coastline. They use computers with satellite images (卫星影像) to find out where and when a hurricane will hit the coast. Sometimes, if a hurricane is strong enough, officials may require people to leave their homes, and travel to a safer place.

Can you imagine flying a plane through a hurricane? If you’re a hurricane hunter, it’s your job! Hurricane hunters fly airplanes to help the National Hurricane Centre make predictions (预测) about hurricanes, and give them the information needed to give warnings. Pilots find out how fast the winds are blowing, how big the hurricane is, and which direction it’s moving in. This helps people to be better prepared for hurricanes as they come near the coastline.

Categories (类别) of Hurricanes

There are five categories of hurricanes. The categories help to make people know how much damage a hurricane may cause because the greater the wind speed, the more dangerous the storm.

Category 1 - Winds 74-95 mph

Winds break branches, pull trees out of the ground and overturn mobile homes.

Category 2 - Winds 96-110 mph

Winds are strong enough to destroy weak doors and windows, and create 8-foot ocean waves.

Category 3 - Winds 111-130 mph

Strong winds cause major flooding near the coast which can destroy homes and businesses.

Category 4-Winds 131-155 mph

Winds are strong enough to destroy some buildings and cause heavy damage to building roofs .

【推荐3】The Terror of the First F5 Tornado

The nonstop high plains wind suddenly fell dead still, leaving the evening air hot and heavy over Lubbock, Texas. Impossibly dark clouds hung low in the sky.

Standing in the yard outside her family’s trailer home, 12-year-old Cindy Keele saw the worry appear in her grandmother's face. “Go in and put on your shoes,” Keele’s grandmother said flatly (断然地). “We have to get to the storm cellar.”

The girl dashed inside. As soon as the screen door slapped shut behind her, hail (冰雹) began rapping against the roof. Keele yelled to her mother, “Grandma says we have to get to the storm cellar!” Then a hailstone the size of a softball smashed through the kitchen window. Another one punched a hole in the ceiling. And then came the sound: the unmistakable, ear-splitting roar of an approaching tornado.

Cindy Keele’s mother was suddenly on the same page. But getting herself, her three kids, and her mother to safety was no simple matter -the shelter was at the opposite end of the trailer park. If they didn’t drive, they’d never make it.

The five moved quickly to the family car, trying to avoid pieces of hail. At last, everyone was in the car.

“My purse!” Keele’s grandmother shouted, “My purse is still in there!”

Keele jumped out of the car and ran back into the house. She fetched the purse and dashed back into the maelstrom (漩涡). She almost made it, “As I ran to the car,” she says, “an enormous hailstone hit me in the back of the neck. I was told it was the size of a soccer ball.” The next few minutes were a blur for the girl. Her next clear memory was of inside the shelter.

“I guess there were 60 of us in there, plus dogs and cats,” Keele says. “The sound outside was deafening. And then, all of a sudden, it got quiet.” Cautiously, the group went up from underground.

“My mother ran straight for our street. What she found was-nothing.” The place where our house had been were pieces of houses, but not pieces of our house. “I’d never seen my mom cry,” Keele recalls softly. “But she was on her knees. She was broken.”

May 11 marks the 51st anniversary of the 1970 Lubbock tornado, the first such storm ever to be classified F5.
