Climate change, pollution, overuse of water and development are killing some of the world’s most famous rivers including China’s Yangtze, India’s Ganges and African’s Nile, WWF said on Tuesday. At the global launch of its report “World’s Top 10 Rivers at Risk”, the group said many rivers could dry out, affecting hundreds of millions of people and killing unique aquatic life.
“If these rivers die, millions will lose their livelihoods, biodiversity will be destroyed on a massive scale, there will be less fresh water and agriculture, resulting in less food security,” said Rayi Singh, secretarygeneral of WWF-India. The report launched ahead of “World Water Day” today, also cited the Rio Grande in the United States, the Mekong and Indus in Asia, Europe’s Danube, La Plata in South America and Australia’s Murray-Darling as in need of greater protection.
Rivers are the world’s main source of fresh water and WWF says about half of the available supply is already being used up. Dams have destroyed habitats and cut rivers off from their flood plains while climate change could affect the seasonal water flows that feed them, the report said. Fish populations, the top source of protein and overall life support for hundreds of thousands of communities worldwide, are also being threatened, it found… The Yangtze basin is one of the most polluted rivers in the world because of decades of heavy industrialization, damming and huge influxes of sediment from land conversion.
Climate change, including higher temperatures, also means serious consequences for fishery productivity, water supply and political security in Africa’s arid Nile basin. Tributaries flowing into the Ganges are drying up because of irrigation, WWF said.
1. What does the text mainly about?
A. Saving fresh water in our life.
B. How to protect our rivers.
C. An important discovery.
D. World’s top 10 rivers are at risk.
2. We can infer from the text that_________.
A. rivers’ dying out could affect food security
B. there are four Asian rivers mentioned in the passage
C. the Yangtze is polluted thanks to the lack of enough tributaries
D. higher temperatures couldn’t affect fishery productivity
3. The top 10 rivers are fast dying as a result of the following EXCEPT_________。

Although April did not bring us the rains we all hoped for, and although the Central Valley doesn’t generally experience the sound and lightning that can go with those rains, it’s still important for parents to be able to answer the youthful questions about thunder and lightning.
The reason these two wonders of nature are so difficult for many adults to explain to children is that they are not very well understood by adults themselves. For example, did you know that the lightning we see flashing down to the earth from a cloud is actually flashing up to a cloud from the earth? Our eyes trick us into thinking we see a downward motion when it’s actually the other way around. But then, if we believed only what we think and we see, we’d still insist that the sun rises in the morning and sets at night.
Most lightning flashes take place inside a cloud, and only a relative few can be seen jumping between two clouds or between earth and a cloud. But, with about 2,000 thunderstorms taking place above the earth every minute of the day and night, there’s enough activity to produce about 100 lightning strikes on earth every second.
Parents can use thunder and lightning to help their children learn more about the world around them. When children understand that the light of the lightning flashing reaches their eyes almost at the same moment, but the sound of the thunder takes about 5 seconds to travel just one mile, they can begin to time the interval (间隔) between the flash and the crash to learn how lose they were to the actual spark (闪光).
According to the author, in the area of the Central Valley____.

A.rains usually come without thunder and lightning.
B.it is usually dry in April
C.children pay no attention to the two natural wonders.
D.parents are not interested in thunder and lightning.

What is TRUE about lightning according to the passage?

A.Only a small number of lightning flashes occur on earth.
B.Lightning flashes usually jump from one cloud to another.
C.Lightning travels 5 times faster than thunder.
D.There are far more lightning strikes occurring on earth than we can imagine.

A.cloud B.lightning strikes C.lightning flashes D.thunderstorms

It can be concluded from the passage that _______.

A.we should not believe what we see or hear.
B.things moving downward are more noticeable.
C.people sometimes may have wrong ideas about ordinary phenomena.

Penguins live together,but each pair has a little piece of ground of their own.When a penguin wants to walk through its neighbor’s ground,it must ask permission.If it does not do that,it will have to fight.Most of the time,penguins live on the water.They eat shell fish and look after their children carefully.
All penguins are good parents—the male penguins are perhaps the best parents in the world. They walk in the sea in the middle of the dark Antarctic water. They choose their wives in the dark.They can only hear them—not see them.Then the female penguins lay their eggs and go away for about two months.The males take care of the eggs.If the eggs get cold,there will be no chicks.There is no food.The snow falls heavily and the wind blows strongly—sometimes at 150 kilometers an hour.The penguins do not move.When the females return from the sea,they will not remember their husbands.It does not matter.Only one thing matters—the eggs.Male penguins never fight—unless a penguin leaves a chick for a minute.They then fight because they all want it.They are strange and wonderful birds.

"Children should not be left unsupervised (无人监督的) to play with a dog." say experts in this week's British Medical Journal. Their advice is part of a review aimed at doctors who deal with dog bites.
"Dog bites and maulings are a worldwide problem, particularly in children." write Marina Morgan and John Palmer. Every year 250,000 people who have been bitten by dogs attend minor injuries and emergency units in the United Kingdom, and half of all children are reportedly bitten by dogs at some time, boys more than girls.
Accurate death figures are difficult to obtain, but in the past five years, two to three cases a year have made news headlines.
Based on the latest medical evidence, they advise doctors how to examine and treat a patient presenting with a dog bite. They discuss the risk of infection and when to refer to specialist care. For travelers bitten abroad, they suggest assessing the risk of rabies(狂犬病).
In terms of prevention, they suggest that children should be taught to treat dogs with respect, avoid direct eye contact, and not tease them. They should be taught not to approach an unfamiliar dog; play with any dog unless under close supervision; run or scream in the presence of a dog; pet a dog without first letting it sniff you; or disturb a dog that is eating, sleeping, or caring for its babies.
"Dog owners also need to change their behavior", says Rachel Besser, a children's doctor and lifetime dog owner, in an article.
"It is clear that not all dog owners appreciate that children should not be left unsupervised with a dog", she says. Just as some parents are obliged to take parenting classes, she would like to see compulsive classes for expectant dog owners to teach them about the responsibilities of dog ownership. Educational programs are also needed to teach children about some precautionary (预防的) behaviors around dogs.
Finally, she would like to see animal doctors advising dog owners about bite prevention, and doctors promoting bite prevention when treating patients who have been bitten by dogs.

A.only happens to a few children B.should be paid attention to

B.Children should be taught not to play with dogs.
C.All the dog owners would like to attend classes on caring for dogs.
D.Some dog owners would like children to be left unsupervised with a dog.
