As millions of playthings are recalled, doctors are reminded that the risks of lead exposure continue for young patients.
Lead is such a well-known health(危害)- perhaps even contributing to the fall of the Roman Empire- that it came as a shock to discover that toys played by children could contain lead. Doctors are now dealing with the aftershocks.
Just how dangerous is this exposure? That’s the question physicians are being asked by parents who find a lead-polluted Elmo, of Dora. Millions of others toys, lunch boxes and pieces of jewelry manufactured in China have been recalled because they contain lead either in the paint that coats them or as a component of the plastic used to make the item more flexible. The lead content in some of the toys recalled this summer was 180 times the amount allowed by law. Some pieces of jewelry were almost 100% lead.
Experts advise that the items do cause a risk and that doctors should urge parents to check the comprehensive lists of recalled products on the Consumer Product Safety Commission’s Web site and return any appearing on those lists to the manufacturers.
If exposure is suspected, a blood test is in order . Since there is no safe level of this universal (普遍存在的) element, the risk face by children for lead poisoning and its accompanying threat of learning disabilities and behavior problems is considerable.
Doctors who have toys in their waiting rooms also are advised to see if any of them have been recalled and to check for chipped, flaking paint-even on those that haven’t yet been recalled—since new announcements of toy risk continue.
1. Why does the author mention “the fall of the Roman Empire”?
A. To tell us a strange story.
B. To warn us to keep away from lead.

D. To show how terrible lead poisoning is.
2.What is Dora according to the passage?
A. The name of a kind of metal.
B. The name of a girl.
C. The name of a toy.
D. The name of a toy company.
3.What should parents do if they are not sure whether their kids have ever touched such toys or not?
A. They should ask the experts for advice.
B. They should have a medical examination.
C. They should have their children blood-tested.
D. They should collect all the toys and check online first.
4. From the report we can infer that_____.
A. children who are exposed to lead have learning disabilities
B. the unsafe toys have all been listed on the website
C. lead is used mainly to make the products flexible
D. some toy and jewelry manufacturers will suffer heavy losses

Mattel Inc. is recalling 4.4 million Polly Pocket toys with magnets（磁铁）after some of them caused serious injuries to children who swallowed magnets that fell off.
Tiny magnets inside the toys may fall off without being noticed by parents and babysitters. The magnets can be swallowed or placed in children’s noses or ears. When more than one magnet is swallowed, the magnets can attract each other and cause intestine perforation（肠内穿孔）which can be deadly.
The Consumer Product Safety Commission（CPSC）received 170 reports of the small magnets coming out of these recalled toys. There were three reports of serious injuries to children who swallowed more than one magnet. All three suffered intestinal perforations that required operation. A 2-year-old child stayed in hospital for seven days and a 7-year-old child was hospitalized for 12 days. An 8-yeal-old child was also hospitalized.
The recalled Polly Pocket toys contain plastic dolls and accessories（附件）that have small magnets. The magnets measure one-eighth inch in diameter and are fixed in the hands and feet of some dolls, and even in the plastic clothing, hairpieces and other accessories to help the pieces stay on the doll or the doll’s house.
The model number is printed on the bottom of the largest pieces on some of the toys. Contact Mattel if you cannot find a model number on your product to determine if it is part of the recall. Polly Pocket magnetic toys currently sold in stores are not included in this recall. The model numbers included in the recall are: B2632, B3158, B3201, B7118, G8605, H1537, H1538 and H3211. The toys were on sales in department stores and toy stores from May 2006 through September 2009 for between $15 and $30.
Consumers should immediately take these recalled toys away from children and contact Mattel for the return of the toys. For more information contact Mattel at 888 597-6597 anytime or visit the company’s Web site.
1.The main purpose of the passage is .

As skies are filled with millions of migrating（迁徙） birds, European scientists say the seasonal wonder appears to be strange. The fatter the bird, the better it flies.
The results of their study led to a theory opposite to a central one of aerodynamics(空气动力学), which says that the power needed to fly increases with weight.
For birds, obviously, the cost of flying with heavy fat is much smaller than we used to think. Researchers found that red knot wading birds double their normal body weight of 100 grams before making their twice-a-year nonstop flight between the British Isles and the Russian Arctic.Distance;5,000 kilometers.
Another study in the magazine Nature measured the advantage of flying in an aerodynamic group which allows birds to save energy by flying smoothly and quietly in the lead bird’s air stream.
Flying in groups, their heart rates were 14.5 percent lower than flying alone, according to Henri, a French scientist. The findings help explain how birds complete difficult migrations. Researchers had thought stronger birds would have the best chance to survive.
The first study suggests that building up fat to be burnt as fuel during the migration is worth more than the energy it take to carry the additional weight.
In the study, researchers said their team studied the birds flown at different body weights during 28 simulated(模拟的)flights. They forced a small amount of special water into the birds’ bodies so that they could measure the amount of energy burnt during the flight.
1.A red knot wading bird of 100 grams will probably weigh ________before making its nonstop migrating flight.
A.50 grams B.100 grams C.150 grams D.200 grams
2.During their migrating flight, red knot wading birds can save energy by flying________.
A. separately B. alone C. in groups D. in pairs
3.A ________red knot wading bird has a better chance to survive during its migrating flight.
A. stronger B. weaker C. thinner D. fatter
4.The best title for this passage may probably be ________ .
A. Birds Thin Down For Journey B. Birds Fatten Up For Journey
C. How Birds Build Up Fat For Journey D. How Birds Burn Energy For Journey

As the new semester begins, millions of college students across the country are trying hard to remember how best to write a paper or, more likely, how best to delay that paper.
Procrastination is the thief of time and a lot of students suffer from it. They can spend whole days in the library doing nothing but staring into space, eating snacks, surfing the Internet, watching videos and looking at other students sitting around them, who, most likely, are doing nothing either.
Paralyzed (使失去活力) by their habit to procrastinate, they write micro blogs about their fears, asking their online friends if they sometimes have the same issue. But this does nothing to break the spell (魔咒).
According to a recent report, 95 percent of us procrastinate at some point and 20 percent of the world’s population are always procrastinating. The figures are disappointing. Procrastinators are less wealthy, less healthy and less happy than those who don’t delay. Procrastinators like to find excuses to justify their behavior, but BBC columnist Rowan Pelling says they are all wrong.
Many procrastinators tell themselves they are perfectionists who work best under pressure. Pelling says this is nonsense, as work done at the last minute is more likely to have mistakes than work done on time. The behavior of procrastinators often makes them feel ashamed, inconveniences others and annoys loved ones.
Pelling also points out that procrastination feels particularly delinquent (过失的）in a society that thinks of speedy action as admirable, and, at times, even as a moral good.
Fortunately, social scientists have thrown their weight behind efforts to understand this behavioral mistake and offer strategies to control it. Piers Steel, a Canadian social scientist and author of The Procrastination Equation, believes human is “designed” to procrastinate. Nevertheless, he suggests a couple of good ways to get through the task at hand.
1.From the first two paragraphs we can learn that _________.
A. procrastination is beneficial to many students
B. many students are under great pressure in their study
C.many students have the habit of delaying finishing their tasks
D. lots of college students work hard to write good essays on time
2.Which behavior belongs to procrastination?
A. Never dream away the time.
B. Always complete the tasks ahead of time.
C. Never put off till tomorrow what should be done today.
D. Always wait to work until the “good mood” or “good time”.
3.According to the passage, which of the following statements is not true?
A. Procrastination makes people waste their time.
B. Procrastinators usually complete their tasks perfectly.
C. Speedy action is considered as a moral standard in the society.
D. Procrastination is common among people.
4.What is most likely to be discussed in the paragraph that follows?
A. Measures to deal with procrastination.
B. Approaches to handling the study pressures.
C. More examples to illustrate procrastination.
D. Introduction to the book The Procrastination Equation.

My friends are often jealous of my good memory. When they were beating their brains to recall how many people attended John’s ninth birthday, I succeeded in reminding them of the details. I told them that Tom, Barbara, Tony and I did; that Mary brought a toy car as a gift, Tom brought a four-in-one game disc…; that John said after blowing out the candles his wish was to be a pilot when he grew up… When Bob, Jim and Elizabeth were quarrelling, faces flush with anger, about the name of the forest where they went camping, I stopped them by detailing to them on which date, which month, which year we visited which forest and ate what food for picnic…
Bob often says, “Lewis, if only I had a memory half as good as you!” Whenever hearing this, a voice shouted from the bottom of my heart, “How I wish God gave me a forgetfulness half as good as you!”
In fact, instead of being proud of my memory, I hate it; I’ve suffered a lot from it, for it is sometimes too good: I can remember everything I’ve experienced, including what I don’t want to remember; indeed, I do hope to forget something!
Barbara and I are best friends from the cradle. In fact, our relationship was already beyond friendship; it was that of lovers. But one day she left me for no reason except that I was too familiar to her to further our relationship. Over the next two months and a half, I couldn’t fall to sleep. While in bed wide awake, I warned myself, “You must forget her, otherwise you will get destroyed.” But my good memory failed me again and again — I could remember how beautiful it was when I first kissed her affectionately and then in turn received even more affectionate responses; I could remember every sweet word she had said to me…
1.The first paragraph is intended to describe ________.
A.how the writer’s friends were jealous of him
B.what a good memory the writer had
C.what happy childhood he shared with his friends
D.what an important part he played among his friends
2.Barbara left the writer ________.
A.for nothing B.because she hated it that he kissed her
C.because their friendship broke D.because she was tired of him
3.Which of the following is NOT TRUE according to the passage?
A.The writer and Barbara had a long-time friendship.
B.The writer, somehow, hated his good memory.
C.The writer was struggling to tear himself off the pain of losing love.
D.Tony’s wish was to be a pilot when he grew up.
4.What the writer suffered the most was that ________.
A.he had got too good a memory B.Barbara left for no reason
C.others were jealous of him D.the sweet past was out of memory

We’re often reminded of the importance of preserving the planet as we see it for future generations—and children at St Oswald’s Primary School in Chester certainly agree.
Nine-year-old Isobel Kelleher from the school’s Hummingbirds class thinks adults need to take note.“Sometimes they can be busy and I don’t think they think they can make a difference，but if everyone does a little bit it all adds up，”she tells HuffPost UK.“We started looking at plastic pollution in our oceans and the things like plastic bags and broken down pieces of plastic that are polluting them.”she says.“Fish can eat the plastic and they can die，or we might even eat the fish ourselves.”
Mr Timms，Isobel’s teacher，has been spearheading a new project at the school which lets children loose creatively to raise awareness of the need to be more environmentally friendly.The entire Hummingbirds class，which is made up of 9 and 10-year-old pupils，has been busy writing poems and creating online video adverts to warn adults about the serious situation of our oceans and wildlife.
Mr Timms thinks children have an important role to play in teaching us how to take care of the things around us.“We sometimes overlook how much we can really learn from children.”he says.“It has been really hard to believe having parents come in saying that their children have been asking them to stop using plastic，and to recycle more，and even stopping them using plastic straws.”
Mr Timms is proud of his Hummingbirds class.“The message that they would like to send to the world is simple:stopping this isn’t someone else’s job，and it won’t be OK if we just leave it.”
1.What can we infer about adults according to Isobel Kelleher?
A. They just pretend to be busy.
B. They haven’t done their part well.
C. They can do nothing to stop pollution.
D. They have started to care about oceans.
2.What is the purpose of the school project?
A. To help adults to learn more about their kids.
B. To remind adults to be friendly to environment.
C. To persuade students to stop using plastic bags.
D. To teach students how to write poems creatively.
3.Why does Mr Timms mention“parents”in Paragraph 4?
A. To prove kids are creative in teaching.
B. To attract people to support his work.
C. To have adults care about education.
D. To show the effects of the project.
4.What is the text mainly about?
A. An inspiring school project.
B. An appeal to stop plastic bags.
C. Serious situations of our planet.
D. Adults’ignorance of environment.
