Imagine a mass of floating waste is two times the size of the state of Texas. Texas has a land area of more than 678 000 square kilometers. So it might be difficult to imagine anything twice as big.
All together, this mass of waste flowing in the North Pacific Ocean is known as the Great Pacific Ocean Garbage Patch. It weighs about 3 500 000 tons. The waste includes bags,bottles and containers—plastic products of all kinds.
The eastern part of the Great Pacific Ocean Garbage Patch is about l 600 kilometers west of California. The western part is west of the Hawaiian Islands and east of Japan. The area has been described as a kind of oceanic desert,with light winds and slow moving water currents. The water moves so slow that garbage from all over the world collects there.
In recent years,there have been growing concerns about the floating garbage and its effect on sea creatures and human health. Scientists say thousands of animals get trapped in the floating waste,resulting in death or injury. Even more die from a lack of food or water after swallowing pieces of plastic. The trash can also make animals feel full,lessening their desire to eat or drink.
The floating garbage also can have harmful effects on people. There is an increased threat of infection of disease from polluted waste,and from eating fish that swallowed waste. Divers can also get trapped in the plastic.
Its existence first gained public attention in l997. That was when racing boat captain and oceanographer Charles Moore and his crew sailed into the garbage while returning from a racing event. Five years earlier,another oceanographer learned of the trash after a shipment of rubber duckies got lost at sea. Many of those toys are now part of the Great Pacific Ocean Garbage Patch.
In August,2009,a team from the University of California,San Diego became the latest group to travel to it. They were shocked by the amount of waste they saw. They gathered hundreds of sea creatures and water samples to measure the garbage patch’s effect on ocean environment.
1.What do we know about the Great Pacific Ocean Garbage Patch?
A. It is made up of various kinds of plastic products.
B. It is a solid mass of floating waste materials.
C. It lies l60 000 kilometers east of California.
D. It is described as a kind of oceanic desert.
2.Why do people pay attention to the Great Pacific Ocean Garbage Patch?
A. Because it may prevent the flow of ocean water.
B. Because the polluted plastic articles will move up the food chain.
C. Because it may be from an island in the pacific.
D. Because ships may be trapped in the floating waste.
3.Which column can you find the passage on a newspaper?
A. Sports and entertainment. B. Media and culture.
C. Environment and society. D. Science and technology.
4.The purpose of writing this passage is to____________.
A. warn people of the danger to travel in the pacific
B. analyze what caused the waste patch in the pacific
C. give advice on how to recycle waste in the ocean
D. introduce the Great Pacific Ocean Garbage Patch

It is hard to imagine that such a small country,the size of Indiana with the population of Alaska,tucked in the Himalaya Mountains,accessible only by two airplanes,is the “Happiest Country’’ in the world and has one of the fastest growing GDP’S in the world.This country is Bhutan,“Land of the Thunder Dragon”,which is located in South Asia and is encompassed by India,China,and Nepal.
Bhutan is the last standing Buddhist Kingdom in the World and,until recently,has preserved much of their culture since the l7th century by avoiding globalization and staying isolated from the world.Internet,television,and western dress were banned from the country up until ten years ago.Over the past ten years globalization has begun to change in Bhutan,but things remain perfectly balanced.
Bhutan is the only country in the world that has a ‘GNH’,which refers to “Gross National Happiness.’’The process of measuring GNH began when Bhutan opened up to globalization.It measures people’s quality of life,and makes sure that “material and spiritual development happen together.”Bhutan has done an amazing job of finding this balance.Bhutan has continually been ranked as the happiest country in all of Asia,and the eighth Happiest Country in the world according to Business Week.In 2007,Bhutan had the second fastest growing GDP in the world,at the same time as maintaining their environment and cultural identity.
In 2008,in Bhutan’s first democratic election,28-year-old Jigme Khesar Namgyel Wang Chuck was elected president of Bhutan.He promises to “maintain a stance (立场)of protection against the worst aspects of globalization,maintaining the ‘Gross National Happiness’.”But Jigme himself is no stranger to globalization.He attended high school at Phillips Academy and university at Wheaton College and then graduated from Oxford.
1.The underlined word “encompassed’’ in the first paragraph most probably means __________ .
A.covered B.surrounded
C.separated D.guarded
2.Why is Bhutan regarded as “the happiest country”?
A.Because it changes its policy and begins to open up.
B.Because it uses “GNH” to measure its achievement.
C.Because it stresses both material and spiritual development.
D.Because it has the second fastest growing GDP in the world.
3.What Can we infer from the last paragraph?
A.The election in Bhutan is far from satisfactory.
B.Globalization has influenced Bhutan’s religion.
C.Jigme’s educational background will cause distrust.
D.People in Bhutan will continue living a happy life.
4.Which of the following shows the structure of the passage?

When you think of the Arctic, you imagine an icy land of pure white snow. Others imagine it as the last really clean place left on Earth. We have polluted the deepest oceans with plastic trash, 1.
German scientists have recently found microplastics in Arctic snow. 2.Sadly, the scientists found 1,800 pieces of microplastic per liter of snow.
How is plastic pollution reaching the Arctic? According to scientists. "It's apparent that the majority of the microplastics in the snow comes from the air." They fall off plastic objects and are moved by the wind, just like dust. 3.Finding these plastics in Arctic snow means that we may breathe them in. An even higher amount of microplastic was found in the snow around cities.
The high concentrations found in snow samples suggest microplastics, which contain rubber or chemicals used in synthetic fabrics(混合纤维), may cause significant air pollution.
4.Scientists cannot answer this question for now, according to the world Health Organization. We do know that our bodies cannot take in "large" pieces of microplastics. However, if the plastics are small enough, they can find ways into our bodies and stay there for a long time. What's more, earlier studies have shown that microplastics may contribute to lung cancer risk, heightening the need to further assess the risks of taking them in, the study said.
Microplastics have also been found in rivers and oceans around the world. Previous research has found that they flow over long distances and into our oceans, damaging ecosystems along the way.5.The waste water then flows into rivers and out to sea, where they are eaten by sea animals. If people then eat these animals, it means that we're eating the plastic as well.
A.Are they bad for us?
B.and now it's the Arctic's turn.
C.so we should take action to protect the world.
D.They mix with ice in the air and fall to the ground as snow.
E.Microplastics are pieces of plastic smaller than 5 millimeters.
F.They start in our water when we wash clothes with plastic fibers.
G.Is plastic pollution doing great damage to our global economy?

Close your eyes and picture the city of Paris.Now imagine the city without its most famous landmark:the Eiffel Tower.
The unthinkable almost happened.
When French engineer Gustave Eiffel built this tower for the Paris World’s Fair of 1889,it was controversial.The iron structure contrasted(对比)sharply with the historic stone buildings of Paris.Eiffel’s four-legged iron archway was supposed to last only 20 years.That’s when Eiffel’s permit to operate the building would expire(过期)and the city could choose to tear it down.
Yet from the beginning.Eiffel had a strategy to save his building.If the Tower was linked to important research,he reasoned,no one would dare to take it down.So he would make it a grand laboratory for science.
Scientific research began just one day after the Tower opened to the public on May 6,1889.Eiffel installed a weather station on the Tower’s third(and highest)floor.He connected instruments by wire to the French weather bureau in Paris.With these,he measured wind speed and air pressure.
In 1903,still worried that his building might be torn down,Eiffel got a clever idea.He asked the French military to conduct its own research on radio communications at the Tower.He even paid the army’s costs.
French army captain Gustave Ferrié worked from a little wooden house at the base of the Tower's southern pillar.From there,he made radio contact with forts around Paris.Convinced of the importance of radio communications,the army set up a permanent radio station at the Tower.In 1910,the city of Paris renewed the structure’s permit for another 70 years.
This year marks the iconic structure’s 125th birthday.Over the years,research conducted there has brought dramatic and unexpected payoffs.During World War I,for instance,the French army used the Tower as a giant ear to receive radio messages.It even led to the arrest of one of the war's most famous spies.
1.What does the author mean by“The unthinkable almost happened”?
A.The Eiffel Tower was almost torn down.
B.Gustave Eiffel was more than an engineer.
C.It took great efforts to build the Eiffel Tower.
D.The Eiffel Tower has served important purposes.
2.The Eiffel Tower was controversial because_____________.
A.it was giant and ugly
B.it would expire too soon
C.some historic buildings had to be removed
D.it didn’t match the historic buildings of Paris
3.How did Gustave Eiffel save the Eiffel Tower?
A.By asking the army to defend it.
B.By showing its importance for tourism.
C.By making it a base for scientific research.
D.By asking the government to renew its permit.
4.The arrest of a famous spy is mentioned to show.
A.the Eiffel Tower has lost its initial value
B.the Eiffel Tower has existed long enough
C.research done in the Eiffel Tower had unexpected payoffs
D.the Eiffel Tower was successfully preserved during the war
