A drought is a period of time when an area or region experiences below-normal rainfall. The lack of enough rainfall, either rain or snow, can cause reduced soil wetness or groundwater, diminished steam low (减少的水流), crop loss, and a general water shortage. Droughts are the second-most costly weather events after hurricanes.

The early effects of a drought maybe difficult to identify right away, so it may take weeks or months to determine that a drought has started. The end of a drought is hard to identify for the same reason. A drought may last for weeks, months, or even years. Sometimes, drought conditions can exist for ten years or more in a region. The longer a drought lasts, the greater the harmful effects it has on people.

Droughts affect people in several ways. Clean drinking water is significant for all life, and sources of water may narrow during a drought. Without the presence of water, people must bring in enough water from elsewhere to survive. Water is also needed for crops to grow. When not enough rainfalls to naturally water crops, they must be watered by irrigation (灌溉). Irrigation is possible only when there is enough water in nearby rivers, lakes, or streams, or from groundwater. During a drought, these water sources are diminished and may even dry up, preventing crops from being irrigated and causing them to die off.

One person studying these problems is Alexandra Cousteau, a National Geographic Emerging Explorer whose latest plan is Blue Legacy. She started Blue Legacy to raise awareness that we live on a water planet and must take care of it. Cousteau, the granddaughter of the well-known ocean explorer Jacques Cousteau, believes that water will be a key issue in this century. She predicts that water problems such as drought, storms, floods, and degraded water quality will create “water refugees”, people moving in search of water. Cousteau stresses that we must do all we can to protect Earth’s valuable freshwater resources.

【推荐1】Would you know what to do if a fire started in your home? Take the time now to review the following safety tips, and your family will be prepared in time of a fire in your home:

    1    

An escape plan can help every member of a family get out of a burning house. The idea is to get outside quickly and safely.     2     So it is important to learn and remember the different ways out of your home.

Stay low

If you can see smoke in the house, stay low to the ground as you make your way to the exit.       3     You will breathe less smoke if you stay to the ground. Smoke naturally rises, so if there is smoke while you are using your escape route,staying low means you can crawl (爬) under most of it.

What if you can’t get out right away?

If you can’t get out fast because fire or smoke is stopping an escape route, you will want to yell for help. You can do this from an open window or call 911 if you have a phone with you.     4     Then, firefighters will have a hard time finding you. The sooner they find you, the sooner you both can get out.

If your clothes catch fire, what should you do?

Your clothes could catch fire during a fire or by accident if you step too close to a candle. If this happens, don’t run! Instead, stop, drop to the ground, cover your face with your hands, and roll. This will cut off the air and put out the flames.     5    

A.An easy way to remember this is: Stop, Drop, and Roll!
B.Smoke from a fire can make it hard to see where things are.
C.Preventing fires is in the first place!
D.Know your way out
E.They will help prepare you for what you need to do in case of a fire.
F.Even if you are scared, never hide under the bed or in a closet.
G.In a fire, smoke and poisonous (有毒的) air hurt more people, than the actual flames (火焰) do.

文章大意:本文是一篇记叙文。讲述了餐馆老板Harden在龙卷风袭来时救她的员工的故事。

【推荐2】A restaurant owner’s remarkable act of heroism saved many lives during a storm in Rolling Fork, Mississippi, which destroyed a local restaurant.

Tracy Harden, the owner of Chuck’s Dairy Bar, rushed her staff into a walk-in cooler moments before a tornado hit the establishment on Friday.

Harden spoke to Good Morning America reporter Robin Roberts on Monday alongside two employees, Barbara Pinkins and Carolyn Washington, who were both in the restaurant when the tornado hit.

As the horrible tornado tore through the local area, Harden said she only had a minute of advance notice before it came moving rapidly through the restaurant.

“I got two text messages back-to-back from my sister and my daughter in Vicksburg and they both said, “There’s a tornado down, get to a safe place.’ At the same time I had my teenage cashier came running towards the back of the building saying, ‘My mother is on the phone and she said there is a tornado down here.’ At that point, most of us were towards the back of the building and the lights flickered(闪烁). And I just shouted, ‘Cooler!’ And my husband opened the cooler door and started pushing us in.”

Harden said that once her husband got them all inside, including himself, “he lost control of the door, the wind took the door and somehow he was able to get the door back.”

“Just before it shut, he looked up and he said, ‘I see the sky,’ so that let us know that this was way worse than anything we could have imagined,” she continued. “And the roof was gone.”

Pinkins, meanwhile, recalled the chaos(混乱场面)before the tornado touched the restaurant, as Harden led people to safety. She said she remembered hearing Harden say,“Calm down. Everybody gets to the cooler!”

“By the time we got to the cooler, I couldn’t hear anything but the ceiling falling,” Pinkins said through tears, hugging Harden.

【推荐3】As wildfires continued to sweep across Australia, the loss of life in the area was reaching astonishing numbers. Ecologists (生态学家) at the University of Sydney said that nearly half a billion animals and plants had been wiped out since the fires began several months before. Images and videos from the area showed kangaroos trying to escape from burning forests and charred (烧焦的) bodies of koalas lying on the ground.

Koalas, which had been already under threat because of significant habitat loss, were hit particularly hard compared with other animals. Ecologists said nearly 8,000 koalas—about one-third of the population in their primary habitat-were believed to have died from the big fires. Professor Dieter Hochuli from the University of Sydney said it wasn’t just the well- known species, such as kangaroos, koalas and emus(鸸鹋), that were in danger. Insects also suffered losses. Additionally, many rare plant species might have disappeared completely.

While animal hospitals were taking in as many animals as possible to treat burns and nursed them back to health, services had overall struggled to keep up with the amount of care needed. And the animals that had survived would have trouble finding food and shelters among the ongoing flames, so they were still in a dangerous situation.

“We’re getting a lot of lessons out of this and it’s just showing how unprepared we are,” Dr. Sussan Ley said. “Now Australia is burning and national parks and our native animals are being destroyed. People have lost homes. People have died. Firefighters have been killed defending communities, most recently last night. There’s no protocols (拟定草案) in place even wildlife carers dont’ have protocols for when they can go in after fire. It’s our national government that is failing us.”

1. What’s the purpose of the second paragraph?
A.To explain why there were so many rare animals in Australia.
B.To show the terrible effect Australian wildfires had on species.
C.To further confirm Professor Dieter Hochuli’s’unique opinion.
D.To warn people to take good care of wild animals and plants.
2. Why were the animals still in danger after surviving the fire?
A.They failed to recover from serious burns.
B.They might be hunted by people for food.
C.They were short of food and shelters.
D.They were unable to get nursing services.
3. What is Dr.Sussan Ley’s attitude towards the national government’s deed?
A.Supportive.B.Unconcerned.C.Doubtful.D.Dissatisfied.
4. What is the main idea of the text?
A.Many rare animal species might have disappeared.
B.Measures should be taken to prevent Australian wildfires.
C.Australian wildfires killed nearly half a billion animals and plants.
D.Ecologists have made great efforts to find the causes of wildfires.
