A new United Nations report shows that fish farming may soon be the world’s most important provider of fish. The Food and Agriculture Organization says fish farming is growing at a rate of 6.6 percent a year.
Fish farming now produces forty-six percent of the world’s supply of fish. That represents a forty-three percent increase from 2006. The report also said fish farming earned more money in 2008 than traditional fisheries.
In fish farming, fish are raised in tanks or small bodies of water called ponds. They are also raised in cages or nets in oceans, lakes and rivers. The report says increased fish farming has helped people around the world eat record amounts of fish. The FAO says each person ate an average of almost seventeen kilograms of fish last year.
However, the FAO says the current yearly wild-fish harvest of ninety million tons shows no improvement. Decreasing numbers of fish and stronger catch limits have reduced the possibilities for catching wild fish. The FAO report says about thirty-two percent of world supplies are overfished. It says these supplies of fish need to be rebuilt at once.
Some scientists have criticized fish farming. They say the nets and cages permit fish diseases and pests to spread. Some fish farming critics doubt whether fish farming can keep growing at the current rate. But Wally Stevens of the trade group Global Aquaculture Alliance says the industry must continue developing to feed growing populations. Mr. Stevens says a one hundred percent increase in fish farming over ten years is necessary to keep providing for people at the current level. He notes that fish farming creates jobs and wealth, especially for people in coastal areas of China.

The UN Environment Programme says that rising temperatures could mean the end for some migrating animals.
Migrating or mobile animals move through several environments as they travel away from the cold of winter to warmer areas. Birds may fly from one part of the World to another, perhaps stopping at feeding grounds on the way. Whales and turtles(海龟) cover vast areas of ocean. The report says that changes in any one of the places which these animals use can cause serious harm. "Obviously these animals have developed their travelling patterns over thousands of years. But climate change is almost certain to be extreme over the next 25 to 50 years and it is extremely unlikely that these animals can change their habits fast enough, "said the report author Dr. Robert Hepworth.
Hardest hit by rising temperatures are turtles. Scientists have found that at higher temperatures, turtles produce far more female eggs than male ones. In parts of Malaysia, turtle birthing sites are producing only females, the report says. It also provides evidence that some turtles are more likely to develop cancer as the waters get warmer.
With birds, the main problem is climate-related damage to important areas at either end of the travels or at resting places along the way. About one-fifth of migrating birds are now in danger because of climate-related changes including rising sea levels, land loss and more violent storms, the report concludes.
Other animals picked out as particularly in danger include:
the North Atlantic Right Whale, whose main food (tiny shrimp) is disturbed by the change in ocean flows.
·the White-Nose Dolphin, which is out-competed by other kinds of dolphins in warmer waters.
The report is not all bad news. Even with major climatic changes, protecting the environment can still help mobile animals to recover. "We need governments to start taking action at the national and international level. The clock is running," said Dr. Hepworth. And some animals are already adapting, with the report mentioning whales that are changing their feeding behaviour, finding new feeding grounds and new foods to eat.

A.The effect of climate change on migrating animals.
B.How animals are adapting to changes in temperature.
C.The actions required to save migrating animals.
D.The need for government policies to prevent global warming.
2.By saying "The clock is running" in the last paragraph, Dr. Hepworth means that" ______"
A.it may be too late to save some animals
B.it is time to start protecting the animals
C.there is not much time to solve the problem
D.it takes time to complete the actions
A.They will only produce female babies.
3.WhVich of the following is mentioned as a consequence of rising temperatures?
A.More storms will affect the ability of whales to find their feeding grounds.
B.20 percent of all birds are likely to die out because of land loss.
C.Migrating animals are likely to start adapting to the changes more quickly.
D.Warmer oceans will increase the competition between different kinds of dolphins.
4.What can be inferred about turtles from the text?
A.They are the only animals besides humans
that suffer from cancer.
B.They have traditionally lived longer than other ocean-based animals.
C.Those born nearer a hotter area are more likely to be female.
D.Most kinds of turtles are likely to die out within 50 years.
In the near future,we may be using our eyes to operate our smart-phones and tablets,even when it comes to playing popular games like Fruit Ninja.
The Gaze Group has been developing eye-controlled computer technology for nearly 20 years.But those devices have been firstly designed to help those with disabilities,and are very expensive.
“After a while,we figured out that probably the best way is to go for a mass-market way,” says Gaze’s Sune Alstrup Johansen.“where everybody would have this available."
Johansen and some of his colleagues have formed a new company,the Eye Tribe,which is hoping to develop the technology on a mass commercial level.
The technology works with the help of the computing device toward the user’s face. After making sure of the user’s eye movements,the technology is then able to easily find where a person’s eyes are moving,and then allow the eyes to control a cursor(光标).
“Our software can then determine the location of the eyes and know where you’re looking on the screen to make sure what you’re looking at,“reads an explanation on the Eye Tribe site.
There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world.Recently Xbox released the Kinect device,which lets users control their Xbox and play certain games using only their hands,legs and voices. But still,most of these devices have been more of a gimmick than a practical way to use one’s hands to control a mobile device.Johansen said a replaceable filter(滤光器)would be a cheap,convenient way for most consumers.
And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

Andy rode slowly on his way to school, day-dreaming about the fishing trip that his father had promised him. He was so busy dreaming about all the fish he would catch that he was unaware of everything else around him.
He rode along until a strange sound drew him to the present. He came to a stop and looked curiously up to the heavens. What he saw shocked and terrified him. A huge swarm of bees filled the sky like a black cloud and the buzzing mass seemed to be heading angrily towards him.
With no time to waste, Andy sped off in the opposite direction, riding furiously—but without knowing how to escape the swarm. With a rapidly beating heart and his legs pumping furiously, he sped down the rough road. As the bees came closer, his panic (惊慌) increased. Andy knew that he was sensitive to bee stings(蜇). The last sting had landed him in hospital—and that was only one bee sting! He had been forced to stay in bed for two whole days. Suddenly, his father’s words came to him. “When you are in a tight situation, don’t panic. Use your brain and think your way out of it. ”
On a nearby hill, he could see smoke waving slowly skywards from the chimney of the Nelson family home. “Bees don’t like smoke,” he thought. “They couldn’t get into the house.” Andy raced towards the Nelson house, but the bees were gaining ground. Andy knew he could not reach the house in time. He estimated that the bees would catch up with him soon.
Suddenly, out of the corner of his eyes, he spotted a small dam used by Mr. Nelson to irrigate his vegetable garden. Off his bike and into the cool water he lived, disappearing below the surface and away from the savage insects. After holding his breath for as long as he could, Andy came up for air and noticed the bees had gone. Dragging himself out of the dam, he struggled up the hilly slope and rang the doorbell. Mrs. Nelson took him inside and rang his mother.
“You’ll really need that fishing break to help you recover,” laughed his mother with relief. “Thank goodness you didn’t panic!” But Andy did not hear her. He was dreaming once again of the fish he would catch tomorrow.
