Around the world, rivers seem to be either flooding or shrinking (缩小). While Pakistan’s rivers have left one-third of that country flooded and millions of people without homes, a drought unseen for 500 years has left Europe’s major waterways almost dry. In the United States, the Kentucky River suffered deadly flooding this summer, while the Colorado River dropped sharply, which brought about water distribution cuts across several states.

There is little disagreement about what’s going on. Scientists have warned for years that our changing climate will cause the frequency of both rainfall and droughts to increase, making the wet wetter and the dry drier, with more extreme impacts on rivers. The question now may be how to manage those waterways affected by climate change and, specifically, what role dams (大坝) should or should not play in relieving the disasters we’ve been seeing lately and will see more of.

Advocates say water storage dams will become more significant which can stop water during flooding and allow it out in times of droughts. Dams, they say, can help relieve climate change by producing clean hydropower (水电). “Dams and hydropower are fundamental to climate relief and adaptation,” says Richard Taylor, a leading hydropower expert.

Not so. People holding opposite opinions claim that dams do more harm than good. Their arguments have long centered on the negative impact most dams have on biodiversity and river ecosystems, and increasing data show that dams actually worsen both floods and droughts. They also point out studies have shown that lakes created by dams often produce far more harmful greenhouse gases than people previously understood.

“Dams are thought to be a climate solution,” says Isabella Winkler, who co-leads International Rivers, a U.S.-based advocacy group. “They have been praised as a source of green energy but they are actually not.” Besides, scientists warn that many existing dams use operating rules based on old climate assumptions. New dams, experts agree, must be built for the worst cases.

文章大意:本文是一篇应用文,主要讲的是在遇到自然灾害时应该怎么挽救自己的生命。

【推荐1】Nobody expects a natural disaster to strike. Neither does anyone know the impact it can have on life. The following measures can save your life in an emergency.

Typhoon

Typhoons occur in the northwestern Pacific Ocean, particularly in exposed regions like the Caroline Islands, the Philippines, and Japan. The best place to hide during a typhoon is a secure basement or a bathroom with no windows. A must-have device is a battery-powered weather radio, through which you will hear evacuation orders or in other cases, instructions on how to survive in your shelter and learn about the weather situation.

Flood

Floods occur more often than any other natural disaster and change the landscape dramatically. They are usually caused by intense rainfalls lasting for days. Don’t try to be the bravest person around and stay in your house. Once you hear the evacuation warning, leave for safer higher grounds with your important papers in a waterproof container.

Avalanche

An avalanche can hit when you are enjoying Alpine skiing in a dreamlike location. It is very fast and disastrous, burying everything in its way under tons of snow. When an avalanche starts, try to move to the side of the slope as fast as you can. If you get buried in the snow, dig an air pocket to be able to keep breathing. Wait for the rescue team to find you and don’t waste your energy shouting or digging frantically. Call out when you hear the team approaching.

Wildfire

Wildfires spread at an amazing speed and destroy everything in their way. If you are caught in a wild fire, use a wet cloth to cover your nose and mouth to ensure that you can breathe. Try to stay upwind of the fire at all times and get close to a pond or river. Stay low and cover yourself with wet clothing, a blanket, or soil until the fire passes.

1. Among the four natural disasters, which one requires people to hide indoors?
A.Typhoon.B.Flood.
C.Avalanche.D.Wildfire.
2. What should those trapped in typhoons probably do when they hear the evacuation orders?
A.Get to a basement or windowless bathroom.
B.Find something solid to hide under.
C.Leave the place where they are.
D.Get a torch in case of a blackout.
3. What do we know from the text?
A.Typhoons occur only in the exposed regions in the northwestern Pacific Ocean.
B.Floods cause the most frequent damage among the disasters mentioned.
C.Those who meet with avalanches are advised to call out the minute they’re trapped.
D.Getting clean air matters most in the case of wildfires, despite the difficulty.

文章大意:本文是一篇新闻报道。文章主要报道了11月8日,一场70年来最强的龙卷风袭击了泽西岛,造成巨大破坏,并让居民陷入极大恐慌。

【推荐3】On November 8th, a tornado, the most powerful in the past 70 years, hit Jersey, causing great damages to the area and leaving the residents in great panic.

“Suddenly, the windows of the waiting room exploded in and dragged everything inside. My cars have been completely destroyed by branches and fences, and my garden is completely gone. There’s no furniture, no fence; everything has been thrown everywhere. At first there was lightning but then a strange noise and strange darkness came over the whole house. It was like being in a scary scene in the movie The Wizard of Oz,” Ashleigh Quail-Charleston, a Jersey resident, told the Bailiwick Express after the tornado that struck overnight on November 1—2 during Storm Ciaran.

The consequence looked like a bomb had gone off: cars hit, roofs with holes, windows broken. “A huge tree leans drunkenly against a block of flats. Piles of branches are piled optionally and pavements are covered with pieces,” said Chris Stone at BBC Radio Jersey. The tornado was powerful and exceptionally rare, caused by a severe thunderstorm that had sent out intense lightning and huge hailstones described as “ice bombs”. The Tornado and Storm Research Organization (Torro) and Jersey Met Office revealed the tornado left a trail of damages 8 km long across the island, and rated its intensity as T6 on an international scale of tornado power.

According to Torro records, this was the most powerful tornado to strike anywhere in the British Isles or Channel Islands since December 7th, 1954 when a tornado struck west London, leaving tremendous devastation, with Gunnersbury railway station torn apart, roofs torn off houses and one car even thrown through the air.

Tornados during Storm Ciaran also hit Sompting in West Sussex and Loders in Dorset. One resident in Loders, Sophie van Hensbergen, described the moment, saying, “The tornado struck with a very, very powerful whistling sound and the windows looked as though we were in a car wash.”

1. Why is The Wizard of Oz mentioned in paragraph 2?
A.To summarize the consequence.B.To introduce the topic.
C.To enrich the readers’ knowledge.D.To help describe the tornado.
2. What does paragraph 3 mainly about?
A.How tornado was rated.
B.What caused the tornado.
C.How severe the tornado was.
D.What should be done to prevent the tornado.
3. What does the underlined word “devastation” mean in paragraph 4?
A.Marks.B.Damages.C.Memory.D.Impression.
4. What is this text?
A.A news item.B.A science report.
C.A movie reviewer.D.A weather forcast.
