1 . CLIMATE CHANGE REQUIRES THE WORLD’S ATTENTION
We have known about climate change for decades. There is little doubt that Earth is getting warmer and warmer (see the graph). A warming ocean and atmosphere along with melting ice and rising sea levels provide evidence of a dramatic change in the global climate.
In 2013, a lot of people were shocked by a news photo of a dead polar bear that was found on Norway’s Arctic island of Svalbard. According to the scientists who found its dead body, all that remained of the polar bear was “skin and bones”. An expert who has studied polar bears for many years said that from the position of its dead body, the bear appeared to have starved and died. Experts claimed that low sea-ice levels caused by climate change meant the bear could not hunt seals as before, so it had to travel greater distances in order to find food. This alarming case showed how the increase in temperature had an impact on Earth’s ecology.
Then what is causing the increase in the global average surface temperature? Climate scientists often mention a key climate process called the “greenhouse effect”, which has two common meanings: the “natural” greenhouse effect and the “man-made” greenhouse effect. The “natural” greenhouse effect refers to the fact that heat from the sun enters the atmosphere and warms Earth’s surface as short-wave radiation. The heat is released back into space at longer wave lengths. Greenhouse gases in the atmosphere, such as methane and carbon dioxide, trap some of the heat, keeping Earth’s climate warm and habitable. Without this process, Earth could not sustain life. However, the “man-made” greenhouse effect has now become a big problem. When people produce huge amounts of extra greenhouse gases by burning fossil fuels, more heat energy is trapped in the atmosphere and causes Earth’s surface temperature to rise quickly.
There is strong and comprehensive evidence that the rise in temperature has led to an increase in extreme weather and natural disasters worldwide, not only causing serious damage, but also costing human lives. Climate scientists have warned that if we do not take appropriate actions, this warming trend will probably continue and there will be a higher price to pay. In fact, news reports are frequently broadcast about extreme rainstorms and heatwaves causing deaths and economic losses.
Continued greenhouse gas emissions will result in further warming and long-lasting changes to the global climate. This requires the attention of people all over the world. Governments need to consider making policies and taking appropriate actions and measures to reduce greenhouse gas emissions. We as individuals can also reduce our “carbon footprint” by restricting the amount of carbon dioxide our lifestyles produce. It is our responsibility to seize every opportunity to educate everyone about global warming, along with its causes and impacts, because this is the most serious issue affecting all of us on this planet.

Traditional Chinese dragon boat races were held in Milan, Italy on Saturday, attracting the participation of more than 500 people.
Among the seven teams was one composed entirely of Italians. The Chinese Chamber of Commerce in Italy organized the event to celebrate the Dragon Boat Festival, which has become a way for the Chinese community to express their longing for their homeland and family. It also offers an opportunity for local people to learn about traditional Chinese culture.

8 . The shark was not an accident. He had come up from deep down in the water as the dark cloud of blood had settled and dispersed in the mile deep sea. He had come up so fast and absolutely without caution that he broke the surface of the blue water and was in the sun. Then he fell back into the sea and picked up the scent and started swimming on the course the skiff and the fish had taken.
Sometimes he lost the scent. But he would pick it up again, or have just a trace of it, and he swam fast and hard on the course. He was a very big Mako shark built to swim as fast as the fastest fish in the sea and everything about him was beautiful except his jaws. His back was as blue as a sword fish’s and his belly was silver and his hide was smooth and handsome. He was built as a sword fish except for his huge jaws which were tight shut now as he swam fast, just under the surface with his high dorsal fin knifing through the water without wavering. Inside the closed double lip of his jaws all of his eight rows of teeth were slanted inwards. They were not the ordinary pyramid-shaped teeth of most sharks. They were shaped like a man’s fingers when they are crisped like claws. They were nearly as long as the fingers of the old man and they had razor-sharp cutting edges on both sides. This was a fish built to feed on all the fishes in the sea, that were so fast and strong and well armed that they had no other enemy. Now he sped up as he smelled the fresher scent and his blue dorsal fin cut the water.
When the old man saw him coming he knew that this was a shark that had no fear at all and would do exactly what he wished. He prepared the harpoon8 and made the rope fast while he watched the shark come on. The rope was short as it lacked what he had cut away to lash the fish.

10 . Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the world forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never be any more.
Animals are more than just beautiful and interesting. They are more than just a source of food. Every animal has its place in the balance of nature. Destroying one kind of animal can create many problems.
For example, when farmers killed large numbers of hawks, the farmers’ stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice.With no hawks to keep down their numbers, the rats and mice multiplied quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid the killing of any animals or plants on the danger list. Slowly, the number of some animals in danger is growing.
1. What can we infer from the passage?A.People have known the importance of animal protection a long time ago. |
B.The number of hawks is on the decrease. |
C.Animals play an important role in people’s life. |
D.Many countries passed laws forbidding the killing of any animal. |
A.Became more. | B.Became less. |
C.Turned black. | D.Ate food. |
