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.www.zxxk.com
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.www.zxxk.com
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.
【小题1】How did the writer introduce the topic of the passage?

“ONE in every 50 Shanghai women has cancer, a total of more than 140,000 women currently living in the city, and cancer statistics are based on citizens with permanent residency(永久居住),” officials from the Shanghai Center for Disease Control and Prevention said ahead of International Women's Day on Friday.
However, they said the city's rate of cancer in women was rising slowly along with its rising number of elderly people. Early screening for breast, colorectal and cervical cancers can help prevent 30 percent of cancer cases.
Breast, colorectal, lung, gastric and thyroid cancers are the five most common cancer forms among women, with breast cancer accounting for 16 percent of Shanghai's new cases each year and colorectal cancer 13 percent. Cervical cancer, although only the 12th leading cancer in women in Shanghai, is particularly common among women between 25 and 54 years old. Dr Zheng Ying, director of the center's tumor prevention and control department, said , "breast, colorectal and cervical cancers accounted for 32 percent of female cancers”. He added, " However, the three types of cancer can be detected and treated properly through early and regular screening. Our main target of women's cancer prevention education this year is breast cancer, cervical cancer and colorectal cancer."The prevention and control of colorectal cancer will be a new public health project this year with the city government promoting a community-based screening program.
Experts say women over 20 should examine their breasts every month and have annual clinical checks after the age of 35. Women over 50 should have mammograms(乳房X线照片) every two years. For cervical cancer, women over 20 should be checked every three years. Women over 50 years old should have annual medical checks. Zheng said anyone with a family history of the three types of cancer should be aware of the need for more frequent examinations and early screening.

Plastic is everywhere because plastic is an extremely useful material. It is cheap, strong and lightweight. What’s more, it can take on nearly any form or shape, from soft and stretchy (有弹性的) to hard and glasslike.
Plastic, however, is far from perfect. It may even be bad for us. Studies now suggest that poisonous chemicals can get out of some types of plastic, get into our bodies, and cause a variety of health problems, including cancer, birth defects and attention deficit hyperactivity disorder (注意缺陷障碍).
Two types of chemicals in particular have raised special concern lately. They are called phthalates (邻苯二甲酸盐) and Bisphenol-A (二酚基丙烷), BPA for short. Not all plastic products contain them. But the ones that do are surrounded by controversy (争议). That’s because experts disagree on how dangerous these chemicals are.
Plastic is a single word, but plastic isn’t just one thing. What all plastics share in common are plasticizers -- special chemicals that allow the material to be changed into nearly any shape or texture. Plasticizers (塑化剂) are added to plastic during the manufacturing process.
Phthalates and BPA are two types of plasticizers that work in different ways. Phthalates add softness to things like shampoo bottles, raincoats and rubber. They are also used in perfumes and makeup. BPA, on the other hand, gives a hard, clear, almost glasslike feel to products such as infant bottles. BPA also appears in food and soda cans, DVDs and other unexpected places.
How do these chemicals get into us? When plastic is heated in the microwave or dishwasher, chewed on or scratched, the chemicals can seep (渗透) out of the plastic. Even though we can’t see them, we eat them, drink them and breathe them in.
Scientists and parents are especially worried about young children, who tend to chew on everything, including plastic. Dozens of countries, including the European Union, Japan, Canada and Mexico have already banned phthalates from products made for children younger than three. California and Washington have done the same. And a number of other states are considering similar rules. As for BPA, Canada became the first country to ban the chemical from baby bottles. A dozen states are considering it.
【小题1】What can we know about the plastic from the first paragraph?

A.Its characters and effects.B.Its wide use and bad points.
C.Its importance and chemicals.D.Its popularity and advantages.
【小题2】Which of the following products contains BPA?
A.A soft plastic cup.B.A pencil eraser.
C.A baby milk bottle.D.A new perfume.
【小题3】Phthalates and BPA can get into us __________.
A.through mouth or noseB.through blood transfusion
C.by feeling plastic productsD.by heating in the microwave
【小题4】What is the passage mainly about?
A.A new ban on plastic products.B.Problems caused by the plastic.
C.Good points of the plastic.D.The use of plasticizers.

Searching for airfares often seems like a game that passengers are bound to lose.
Prices change from day to day, even minute to minute. Looking through multiple websites for the best deal can be a big challenge. Even when you do book, there’s no guarantee that you are going to get the best price.
“You just don’t know when to pull the trigger. It’s not like buying anything else I can think of,” said George Hobica, founder of Airfarewatchdog.com.
Harriet Levy paid $179 for a recent round-trip flight on American Airlines between New York and Fort Lauderdale, Florida. Sitting just one row behind her, Shirley Harrison paid $215. A few rows back, Ellis and Dianne Traub paid $317 each. There were at least 12 fares on the flight, ranging from $169 to $360.
There’s no reason for it, Harrison said.
Fares can vary significantly in just a few hours. One Delta flight from New York to Los Angeles jumped from $755 to $1,143 from a Friday to Saturday in late April, then fell to $718 on Sunday.
The flight was one of a dozen the Associated Press (美国联合通讯社)followed over three months for a vacation between July 16 and 22. The number one finding: avoid booking tickets on weekends. It’s the most expensive time to buy.
There’s no way to guarantee the best fare. But before booking, travelers should pay attention to this additional advice:
● Book on Tuesday, Wednesday and Thursday. That’s when airlines most often offer sales.
● Buy in advance, but not too early. The best time is four to six weeks before traveling. In general, prices for any given flight are highest eight to ten weeks and two to three weeks in advance.
● Make use of social media. Airlines are giving more benefits like exclusive (独家) sales to travelers who interact (互动) with them on Twitter and Facebook. Those specials are often gone within hours.
● The so-called discount airlines – JetBlue, Air-Tran, Southwest and Frontier – adjust their fares less frequently than other airlines, so you can feel more confident that the price will stay the same. But their prices aren’t always the lowest. Researching multiple airlines’ fares is the only way to get a good deal.
【小题1】 What can we infer from the first sentence of the text?

A.Passengers are unable to search for airfares.
B.Airlines often play games with passengers.
C.Airfares are set in different situations.
D.It’s difficult for passengers to get the best price.
【小题2】The underlined phrase “pull the trigger” in Paragraph 3 probably means _______.   
A.startsearchingB.getthehighestprice
C.makeapurchaseD.getonboardtheplane
【小题3】By using a lot of figures, the author intends to _______.
A.show there is standard price for every single airline
B.discover the rules behind airfares
C.guarantee passengers a low price
D.prove airfares can vary widely
【小题4】Passengers are advised to book flights _______.
A.in the middle of the week
B.on special websites
C.several months before traveling
D.with airlines which are famous for offering discount prices

Cold weather can be hard on pets, just like it can be hard on people. Sometimes owners forget that their cats are just as used to the warm shelter as they are. Some owners will leave their animals outside for a long period of time, thinking that all animals are used to living outdoors. This can put their pets in danger of serious illness. There are things you can do to keep your animal warm and safe.
Keep your pets inside as much as you can when the weather is bad. If you have to take them out, stay outside with them. When you’re cold enough to go inside, they probably are too. If you must leave them outside for a long time, make sure they have a warm, solid shelter against the wind, thick bedding, and plenty of non-frozen water.
If left alone outside, dogs and cats can be very smart in their search for warm shelter. They can dig into snow banks or hide somewhere. Watch them closely when they are left outdoors, and provide them with shelter of good quality. Keep an eye on your pet’s water. Sometimes owners don’t realize that a water bowl has frozen and their pet can’t get anything to drink. Animals that don’t have clean and unfrozen water may drink dirty water outside, which may contain something unhealthy for them.
【小题1】What do we learn about pets from Paragraph 1?

A.They are often forgotten by their owners.
B.They are used to living outdoors.
C.They build their own shelters.
D.They like to stay in warm places.
【小题2】Why are pet owners asked to stay with their pets when they are out in cold weather?
A.To know when to bring them inside.
B.To keep them from eating bad food.
C.To help them find shelters.
D.To keep them company.
【小题3】 If pets are left on their own outdoors in cold weather, they may ___.
A.run short of clean water B.dig deep holes for fun

What Is a Boy?
Between the innocence of babyhood and the seriousness of manhood we find a delightful creature called a “boy”. Boys come in different sizes, weights, and colors, but all boys have the same belief: to enjoy every second of every minute of every hour of every day and to fill the air with noise until the adult males send them off to bed at night.
Boys are found everywhere – on top of, under, inside of, climbing on, swinging from, running around, or jumping to. Mothers spoil them, little girls hate them, older sisters and brothers love them, and God protects them. A boy is TRUTH with dirt on its face, BEAUTY with a cut on its finger, WISDOM with chocolate in its hair, and the HOPE of the future with a snake in its pocket.
When you are busy, a boy is a trouble – maker and a noise. When you want him to make a good impression, his brain turns to jelly or else he becomes a wild creature destroying the world and himself with it.
A boy is a mixture – he has the stomach of a horse, the digestion (消化) of stones and sand, the energy of an atomic bomb, the curiosity of a cat, the imagination of a superman, the shyness of a sweet girl, the brave nature of a bull, the violence of a firecracker(鞭炮), but when you ask him to make something, he has five thumbs on each hand.
He likes ice cream, knives, saws, Christmas, comic books, woods, water (in its natural habitat), large animals, Dad, trains, Saturday mornings, and fire engines. He is not much for Sunday schools, company, schools, books without pictures, music lessons, neckties, barbers, girls, overcoats, adults, or bedtime.
Nobody else is so early to rise, or so late to supper. Nobody else gets so much fun out of trees, dogs, and breezes. Nobody else can put into one pocket a rusty knife, a half eaten apple, a three-feet rope, six cents and some unknown things.
A boy is a magical creature – he is your headache but when you come home at night with only destroyed pieces of your hopes and dreams, he can mend them like new with two magic words, “Hi, Dad!”
【小题1】The whole passage is in a tone (语气) of _________.

A.humor and love B.anger and disappointment 
C.hope and expectation D.confidence and imagination 
【小题2】What’s the meaning of the underlined sentence?
A.He has altogether five fingers. 
B.He is slow, foolish and clumsy. 
C.He becomes clever and smart. 
D.He cuts his hand with a knife. 
【小题3】According to the writer, boys appreciate everything in the following except _________.
A.ice cream B.comic books 
C.Saturday mornings D.Sunday schools 
【小题4】What does the writer feel about boys?
A.He feels curious about their noise. 
B.He is tired of these creatures. 
C.He is amazed by their naughtiness. 
D.He feels unsafe staying with them.
