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.

It’s the place where smart people make smart machines work even smarter. It’s also in the heart of sunny California, a great place to start a family and raise kids. What could be better?
But something is happening to their children. Up until the age of two they develop normally. But then everything seems to go backwards. The children become locked into their own small world, unable to communicate at all.
They call it the “curse(诅咒) of Silicon Valley,” but the medical name for the condition is autism. It used to be thought that autism was a kind of mental illness. Now doctors are sure that it is a neurological disease passed down genetically. It seems that the people leading the communications revolution are having children who cannot communicate at all.
But even the parents have trouble communicating. Asperger’s Syndrome(综合症) is a mild version of autism（自闭症）. People who have it are highly intelligent and often brilliant with numbers or system but have no social skill. This very combination of symptoms makes Asperger’s sufferers into perfect computer professionals.
The Asperger’s sufferer has always been a well—known figure in popular culture. He or she was the abnormal but devoted scholar or the strange uncle or auntie who never married. But the high numbers of such people in Silicon Valley mean that they can meet others who understand them and share their interests. And while they might not be personally attractive, they can earn truly attractive amounts of money. They can get married and have kids. Unfortunately, many of the children of two Asperger’s parents seem to be developing serious autism.
There is little anyone can do. It takes hours of work just to make autistic child realize that anyone else exists. And there is no cure in sight. Some argue that no cure should be found. “It may be that autistics are essentially different from normal people, but that these differences make them invaluable for the evolution（进化）of the human race,” says Dr. Kirk Whilhelmsen of the University of California. “To get rid of the genes for autism could be extremely bad.”
It seems that the children of Silicon Valley are paying the price of genius.What can we learn about autism according to the passage?

| B．People with autism can’t find people sharing their interests. |
| C．It is believed to be a kind of mental illness that can be cured. |

Why do people call autism “curse of Silicon Valley”？
| A．Because autistic people live in Silicon Valley. |
| B．Because people with autism will be driven out of Silicon Valley. |
| C．Because many people working in Silicon Valley have autism children. |
| D．Because people with autism are not personally attractive and not liked by others. |
What can we know about Asperger’s Syndrome according to the passage?
| A．Asperger’s sufferers never get married and have children. |
| B．Asperger’s sufferers are perfect computer professionals. |
| C．Asperger’s sufferers are ashamed of themselves and locked into their own world. |

“Aw, isn't it cute?”
That, right there, is the officially accepted response to any animal contact（接触） the world over. Animals are cute. They're there to be photographed, loved, and occasionally fed. But you know what? Not all animals are cute, or lovely, or even nice. Some of them are a real pain in the neck.
When you travel, you come into contact with all sorts of animals you’ve never heard of before. Some of them are amazing creatures that you'll talk about for the rest of your life. Some of them are just annoying. So, at the risk of causing anger among animal lovers around the world, here are some of the world's most annoying animals.
Vervet monkeys, South Africa
You'll immediately notice two things about Vervet monkeys: they have a bright blue bottom; and they'll steal any food that's not locked in a bank safe. I recently spent some time in South Africa, and watched as monkey after monkey dived in from the trees and stole everyone's food. Get your own food, Vervets! My sandwich was expensive!!
Kea parrots, New Zealand
I have never seen one of these birds before but from what I've been told they are more annoying than a spoilt kid. From biting the paint off your car doors to stealing people's passports, Keas are probably the most curious, and therefore annoying, animals in the world. And they're New Zealanders. That makes sense!
Kangaroos, Australia
Another well-known food-stealer, kangaroos are loved by tourists, eaten by Australians, and generally enjoy making trouble for others. Go on a camping trip anywhere in Australia, and watch how long your bags of food last. Turn your back for 15 minutes and the camp will look like thieves have turned the place upside down.
Grizzly bears, USA
They look pretty cute, grizzly bears. You almost want to go up and give them a hug. Unfortunately, it wouldn't end well. In fact, one of the world's most huggable creatures is also the one most likely to kill you just because it can. Oh, and it'll steal your picnic basket, too.The author uses the underlined expression “pain in the neck” to suggest .

About 18,000 refugees (难民) from Burma have come to the United States each year since 2007. Some have settled in Howard County, Maryland between Baltimore and Washington. A local school began teaching English to the children of the refugees. But while the children learned the language, their parents did not. That made communication with teachers arduous.
At present, almost fifty children from Burma attend Bollman Bridge Elementary School. Laurel Conran is a teacher there. She said, “The main idea is the global idea.” She teaches English to speakers of other languages. One of her students is Tha Neih Ciang. Another student is Tha Neih’s mother, Tin Iang. Ms. Conran practices English with Tin Iang at the mother’s workplace. Many refugees from Burma work at Coastal Sunbelt Produce, a supplier of fruits and vegetables to restaurants and other businesses.
Laurel Conran started classes at the company to help refugees from Burma learn English. Laurel Conran said, “The program is a six-week session. It’s once a week, on every Wednesday, from twelve to one o’clock. So every Wednesday I go to Coastal Sunbelt.” As the workers eat lunch, they also practice their new language skills.
Lisa Chertok has a child at Bollman Bridge. She is also a manager at Coastal Sunbelt. She helped Ms. Conran develop the lessons, which she says have really helped. Lisa Chertok said, “Well, when the Burmese employees got here, they were very, very shy. Now I find that they are more outspoken than before. They’re more communicative. As parents, they are also more involved in their children’s school.”
Jonathan Davis is the headmaster of Bollman Bridge Elementary School. Mr. Davis hopes the lessons will help these parents feel better about communicating with the school. He said, “Even as simple as making a phone call to say that their son or daughter is sick, even if that’s the amount of English that they have got from the program, that truly will help us.”What does the underlined word “arduous” in Paragraph 1 mean?
| A．Interesting. | B．Necessary. |
| C．Difficult. | D．Surprising. |

| A．neither the children nor the parents could speak English |
| B．the parents liked communicating with the teachers |
| C．the parents could help their children speak English |
| D．the children could speak very good English |

My husband is reading The Secret Garden aloud to our kids. They are at the part where Mary has told Colin that she’s found the garden her mother loved. It’s an exciting moment. But the passage I’m waiting for is a few chapters on, after Colin has tasted his first breaths of fresh air and Mary has grown strong running in the garden. It’s just a detail, but my kids will notice it: a delicious description of roasted potatoes and eggs.
We have a tradition of trying foods from the books we read aloud. It started when we read Elizabeth Enright’s The Saturdays, and one of the boys asked, “What are petit fours?” An answer, my husband and I felt, wouldn’t be as good as a sample. So one Saturday we all sat down having tea and little cakes, covered with pink, green, and yellow. It was exciting for the kids to try a dessert they had learned about in a book. The petit fours they tried didn’t tell them what it was like to live in New York City 60 years ago, but tasting them made the book’s words alive.
Later, when we read C.S. Lewis’s The Lion, the Witch and the Wardrobe, we had Turkish delight. We read The Penderwicks, written by Jeanne Birdsall, and had gingerbread (姜饼). We read Paddington Bear and tried marmalade.
Soon we will reach the part of The Secret Garden where Mary, Colin, and Dickon roast potatoes and eggs in a small oven (炉) in the earth. My kids will go out into the woods to find the perfect place for an oven of our own. Yes, we’ve eaten potatoes and eggs, but never in the open air.

| A．will look for a secret garden in the woods |
| B．will read The Secret Garden in the open air |
| C．will cook potatoes and eggs in the woods |
| D．will eat roasted potatoes and eggs at home |
Which of the following could be the best title of the passage?
| A．The best way to make kids learn |
| B．Eating means more than reading |
| C．The taste of a good book |
| D．Our roasted potatoes and eggs |
Though the facts that too many people on earth and a too rapid increase in the number added each year are not in argument, we always begin the discussion of "population as global issue" with what most persons mean like this. It was quite right to compare demographic growth to "a long, thin powder fuse(导火线)that bums steadily and hesitatingly until it finally reaches the charge and explodes".
To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history, we find that populations have been virtually stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. There was high fertility(生育)in most places, but this was usually balanced by high mortality. For most of human history, it was seldom the case that one in ten persons would live past forty, while infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.
This pattern is important to notice. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden
enthusiasm for more children, but an improvement in the conditions that traditionally have caused high mortality.
Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8000 B.C. till approximately 1650 A.D. In the first period of some 9,600 years, the population increased from some 8 million to 500 million in 1650. Between 1650 and 1975, the population has increased from 500 million to more than 4 billion. And the population reached 6.2 billion throughout the world by the year 2000, One way to appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000 B.C. and 1650, an average of only 50,000 persons was being added annually to the world's population, At present, this number is added every six hours. The increase is about 800000,000 persons annually.The underlined word "demographic" in Paragraph l means .
| A．extinction of human |
| B．statistics of human population |
| C．death rate of human |
| D．development of human population |
Which of the following demographic growth patterns is most similar to the long thin powder fuse?
| A．A slow growth for a long time and then a period of rapid, dramatic increase. |
| B．Too many people on earth and a few rapid increases in the number added each year. |
| C．A virtually stable or slightly decreasing period and then a sudden explosion of population. |
| D．A long period when death rates exceed birthrates and then a short period with higher fertility and lower mortality. |
During the first period of demographic history, societies were often in danger of extinction because .
| A．only one in ten persons could live past 40. |
| B．our ancestors had little enthusiasm for more children |
| C．there was higher mortality than fertility in most places |
| D．it was too dangerous to have babies due to the poor conditions |
The author of the passage intends to .
| A．warn people against the population explosion in the near future |
| B．find out the cause of rapid increase in population in recent years |
| C．present us a brief and clear picture of the demographic growth |
| D．compare the demographic growth pattern in the past with that after 1650 |
