Imagine an area 34 times the size of Manhatta...

Imagine an area 34 times the size of Manhattan. Now imagine it covered ankle-deep in plastic waste—a total of about 19 billion pounds of garbage. 1..

“We’re being overwhelmed(淹没) by our waste,”said Jenna Jambeck, an environmental engineer who led the 2015 study that determined this astonishing number. 2., unless something is done to stop the tide of garbage.

Plastic—a widely-used material—has in many ways been a benefit to humans but it has also caused a growing problem. Today, plastics are the No.1 type of garbage found in the sea. Ocean Conservancy, a nonprofit that organizes an annual coastal cleanup event worldwide, said plastic waste makes up around 85 percent of the garbage collected from beaches and oceans.

Ocean Conservancy says plastics are believed to threaten(威胁)at least 600 different wildlife species(物种). 3.; a growing body of evidence suggests humans are consuming plastics through the seafood we eat. A research suggests some plastics could be poisonous to humans, and could potentially increase the risk of health problems.

4.. At the Economist World Ocean Summit this week, ten nations announced to reduce plastic sea liter as part of UN Environment's CleanSeas campaign. 5.Corporations also have a role, as do individuals. We can start by thinking twice before using single-use plastic products—and when we do use them, we should take care to properly throw them off or recycle.

A.The following is what we should do

B.And it’s not just wildlife that’s threatened

C.And this figure is likely to double by 2025

D.But it’s not just countries that need to do their part

E.By 2050,that figure is expected to rise to 1000 pieces

F.That’s how much plastic waste ends up in our oceans every year

G.All of us have an important role to play in dealing with the problems

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 slowly 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.How did the writer introduce the topic of the passage?

A. By giving an example.       B. By listing the facts.

C. By telling a story.           D. By giving a comparison.

2.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 land.

3.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 products will affect the food chain.

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 KhesarNamgyel 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?

A.  B.

C.  D.

Imagine that you’re an actor or actress performing in a play for the first time. You’ve learned all your lines and you know where to walk on stage.

In the 1990s, when an area of Brazilian rainforest the size of Belgium was cut down every year, Brazil was the world’s environmental villain (反派角色) and the Amazonian jungles the image of everything that was going wrong in green places. Now, the Amazon ought to be the image of what is going right. Government figures show that deforestation fell by 70% in the Brazilian Amazon region during the past decade. If clearances had continued at their rate in 2005, an extra 3.2 billion tonnes of carbon dioxide would have been put into the atmosphere. That is an amount equal to a year’s emissions from the European Union. Arguably, then, Brazil is now the world leader in addressing climate change.

But how did it break the vicious cycle (恶性循环)? The answer, according to a paper is that there was no silver bullet but instead a three-stage process in which bans, better governance in frontier areas and consumer pressure on companies worked.

The first stage ran from the mid-1990s to 2004. This was when the government put its efforts into bans and restrictions. The Brazilian Forest Code said that, on every farm in the Amazon, 80% of the land had to be set aside as a forest reserve. As the study observes, this share was so high that the code could not be followed --- or enforced. This was the period of the worst deforestation. Soybean prices were high and there were a vast expansion of soybean farming on the south-eastern border of the rainforest.

During the second stage, which ran from 2005 to 2009, the government tried to boost its ability to police the Amazon. Brazil’s president made stopping deforestation a priority, which resulted in better co-operation between different bits of the government. The area in which farming was banned was increased from a sixth to nearly half of the forest.

The third stage, which began in 2009, was a test of whether a system of restrictions could survive as soybean expansion continued. The government shifted its focus from farms to counties (each state has scores of these). Farmers in the 36 counties with the worst deforestation rates were banned from getting cheap credit until those rates fell.

By any standards, Brazil’s Amazon policy has been a success, made the more remarkable because it relied on restrictions rather than rewards, which might have been expected to have worked better. Over the period of the study, Brazil also turned itself into a farming superpower, so the country has shown it is possible to get a huge increase in food output without destroying the forest. Moreover, the policies so far have been successful among commercial farms who care about the law and respond to market pressures. Most remaining deforestation is by small holders who care rather less about these things, so the government faces the problem of persuading them to change their ways, too. Deforestation has been slowed, but not yet stopped.

1.Brazil is considered to play a leading role in dealing with climate change because ________.

A.it has rainforest as large as Belgium.

B.it has cut down too much rainforest.

C.it has taken action to reduce deforestation.

D.it sent 3.2 billion tons of carbon dioxide into the air.

2.The underlined phrase “silver bullet” in Paragraph 2 most probably refers to _______.

A.a powerful weapon. B.an effective solution.

C.an intelligent device. D.a golden opportunity.

3.What can we infer from the last paragraph?

A.Brazil has successfully eliminated deforestation.

B.All the farmers care much about forest protection.

C.Small farm holders are a headache for the Brazilian government.

D.Both the food output and the forest in Brazil have greatly increased.

4.What can be the best title of the passage?

A.Cutting Down on Cutting Down. B.Brazil, the World Leader in Farming.

C.Restrictions Outperforming Rewards. D.Former Awareness Working Wonders.

Imagine turning on the GPS and seeing an image of your car from above. As the car drives, the map follows along in real time, informing you of any traffic, pedestrians, animals or other things nearby. Routes and names of road appear over the live stream. It's like the map has come to life.

This type of map isn't available yet. But it could be very soon. In 2014, the WorldView-3 satellite was sent into space. Even though it orbits Earth at more than 370 miles (600km) away, it can take images of objects on Earth that are just 10 inches (25cm) across. Looking all the way from outer space, it can make out a smart phone held in your hand. It can tell what types of cars are travelling down a road. But it can't identify your face or read the cars' license plate numbers.

According to some reports, this satellite and other US satellites have the technology to take even sharper images, with a resolution of up to around 4 inches (10cm). But US law forbids making these super-sharp pictures public. But the idea that anybody might be able to spy on the entire Earth in such detail may seem scary. Live, high-detail satellite mapping could be used to keep tabs on anybody at any time, without the person's knowledge. Ray Purdy of University College London told CNN that he couldn't imagine what this could mean for privacy. "Most satellites are commercially owned, so if you have money, you can have that imagery. It means anyone can spy on anyone." he said.

At the same time, live, detailed maps of the Earth's surface could aid humanity in amazing ways. Satellite images can help experts track storms as they form and chart their paths. At high detail, live maps of a disaster area could quickly reveal people in need of rescue as well as the safest routes in or out. Satellites images are already helping the police catch illegal fishing operations. Higher detail may make it possible to catch other criminals in the act. The images could also make it easier for farmers to watch over their crops or for scientists to find minerals. Also, these images play a very important role in monitoring the health of forests and other landscapes.

What do you think? Would you like to see everyone accessing high-detail live maps of the Earth's surface? Please share your idea with us on the website.

1.How does the author introduce the topic of the passage?

A.By telling a story.

B.By supposing a situation.

C.By making a comparison.

D.By using a research finding.

2.What can the WorldView-3 satellite do?

A.Tell how a person looks.

B.Identify what a pedestrian is holding.

C.Help farmers sow seeds for their crops.

D.Read a running car's license plate number.

3.What kind of feeling was expressed in Ray Purdy's words?

A.Regret.

B.Excitement.

C.Concern.

D.Sympathy.

4.What's the best title of the passage?

A.Anyone can spy on anyone

B.Criminals have nowhere to hide

C.More satellites into space: good or bad?

D.A live map of everywhere on Earth:scary or cool?

Sacagawea was born in 1788 in an area near the Rocky Mountains that is now part of Idaho. She was part of the Shoshone tribe where her father was the chief.

When Sacagawea was 12, her tribe (部落) was attacked by the Hidatsa tribe. Sacagawea was taken to North Dakota to live with the Hidatsa. A few years later, she was sold into slavery and forced to marry Toussaint Charbonneau, a French Canadian fur trapper.

In 1804, Captains Meriwether Lewis and William Clark arrived in the area looking for guides. They were sent by President Thomas Jefferson to explore the Louisiana Purchase and the lands to the west.

Lewis and Clark hired Toussaint Charbonneau and asked him to bring along Sacagawea so she could interpret when they reached the Shoshone tribe.

Sacagawea was able to help out with much more than interpreting. She showed the men how to collect edible roots and other plants. She also helped to save important supplies and maps when her boat capsized (翻) in the river during a squall. The men were impressed with her quick action and named the river after her.

The journey across the western lands wasn’t easy. Everyone was often hungry and cold. It was especially hard for Sacagawea who had her infant son to carry and feed.

Clark wrote in his journal that Sacagawea was one of the most valuable members of the group. She spoke both Shoshone and Hidatsa and was able to keep things peaceful when the group met up with the Native Americans.

Sacagawea was the only woman on the expedition. Unlike the men, Sacajawea did not receive any payment for her part in the journey, despite her important role in helping the group return safely.

Not much is known of Sacajawea’s life after the expedition ended in 1806. Some think that she died a few years later and others say that she returned home to the Shoshone and lived for another seventy years.

You have heard the expression “horse sense”. As you may imagine, it came from the time when the majority of people traveled in vehicles drawn by horses. A horse does have a lot of common sense, and there are many true stories about horses having saved their drivers from danger of death.

Today for the most part, people travel by train, ship, airplane, and car, but very little by the use of horses. Modern vehicles are propelled by engines, and an engine does not have any sense. In case of danger, many horses could be depended on to help. Not so with the engine; the driver must do all the things.

In recent years, the speed of travel has increased greatly. With the increased speed comes greatly increased danger. The driver of a powerful engine needs to be careful. A moment of being careless may cost a life. In order to drive today, a person must be able to see clearly, and he must learn and follow carefully the rules for safety on the road. Greater attention is the price we pay for using a machine instead of a horse.

1.The passage mainly talks about ______.

A. engines　　 　　　 B. safe driving

C. using horses　　 D. modern machines
