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 Africa’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（水生的）life．
“If these rivers die，millions will lose their livelihoods，biodiversity（生物多样性）will be destroyed on a massive scale，there will be less fresh water and agriculture，resulting in less food security，”said．Rayi Singh，secretary—general 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（流入）of sediment（积淀）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（支流）flowing into the Ganges are drying up because of irrigation，WWF said．

“BANG!” the door caused a reverberation (回声)．It was just standing there, with Father standing on one side, and I on the other side．
We were both in great anger．“Never set foot in this house again!” stormed Father．With tears welling up in my eyes, I rushed out of the flat and ran along the street．
The street lights were shining rather desolately(凄凉的)．I wandered aimlessly．
A young father who held a child in his arms walked past me．I felt as if I saw my childhood from another space: happy and harmonious．
But now… I don’t know whether it is because I have grown up or because dad is getting old．We differ in our ways of thinking．He always imposes his opinions and codes of behavior on me．Whenever I do something wrong, he never admits it．We are just like two people coming from two different worlds．It feels like there is an iron door between us that can never be opened．
I wandered the streets, without a destination in mind．My heart was frozen on this hot summer night．As I walked on there were fewer and fewer people on the streets, until I had only the street lights to keep me company．When I finally reached the high-rise apartment block in which I lived, I saw that the light was still on．
In fact, it was nothing．Perhaps, dad was throwing away some of his old stamps．Perhaps he thought they were useless．I never had the courage to tell him that I liked collecting stamps．I can’t stand his outrageous(蛮横的) words: “ I can throw you away, let alone these old papers．”
All the lights were off except father’s．
Dad was always like this．Maybe he didn’t know how to express himself．After shouting at me, he never showed any mercy or any moments of regret．After an argument he has the habit of creeping up in my sleep and then tucking me underneath the covers．
This was how he always was．He has been a leader for so long that telling everyone else what to do has become his second nature．
The light was still on．“Am I wrong?” I whispered, maybe… With the key in hand, I was as nervous as I had ever been．At last, I decided to open the door．As soon as I opened the door, tears ran down my cheeks．I suddenly realized that the iron door that I had imagined between us did not exist at all．Love – is second to none．

The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two pieces will probably hit the southern half of the Earth.
On 17 July, a piece four kilometers wide enters the Earth’s atmosphere with a massive explosion. About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people drowned.
Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the Earth are already dead, but the north won’t escape for long. Because of the explosions, the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. The sun won’t be seen again for many years. Wars break out as countries fight for food. A year later, no more than 10 million people remain alive.
Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a piece of object in space. The dinosaurs couldn’t live through the cold climate that followed and they died out. Will we meet the same end?

At the beginning of this century, medical scientists made an interesting discovery; we are built not just of flesh and blood but also of time. They were to show that we all have “a body clock” us, which controls the and fall of our body energies, us different from one day to the next.
The of “a body clock” should not be too since the lives of most living things are controlled the 24 hour night-and-day cycle. We feel and fall asleep at night and become and energetic during the day. If the 24 hour-cycle is , most people experience unpleasant . For example, people who are not to working at night can find that of sleep causes them to badly at work.
the daily cycle of sleeping and , we also have other cycles which longer than one day. Most of us would that we feel good on some days and not so good on ; sometimes our ideas seem to flow and at other times, they do not exist.
