WASHINGTON (AP) — A chemical has caused a global food safety scare. In the U.S., White Rabbit candies from China were recalled(召回) after melamine(三聚氰胺) was found in California and Connecticut. Melamine levels in imported Chinese candies recalled in California were as high as 520 parts per million, about 200 times greater than the level set on Friday by the FDA (The Food and Drug Administration) for "acceptable" risk.
And Friday, a New Jersey company announced it was recalling a yogurt-type drink from China, Blue Cat Flavor Drink, after FDA testing found melamine.
No illnesses have been reported in the U.S., but experts are checking for any increase in reports of heath problems.
The FDA says baby formula(配方) sold here is safe, because producers do not use any materials from China. But officials expect more melamine recalls as they continue to test products in ethnic(少数民族) markets.
“However, tiny amounts of melamine, are not harmful in most foods, except baby formula,” said U.S. government experts Friday.
The FDA said Friday its safety experts had concluded that eating a minuscule amount of melamine — 2.5 parts per million — would not raise health problems, even if a person ate food every day that was infected with the chemical.
“It would be like if you had a million grains of sand and they were all white, and you had two or three that were black, that's kind of the level,” said Stephen Sundlof, director of the FDA’s food safety program.
The FDA guideline is meant to help federal and state investigators(调查员) check for infected foods from China at ports(港口) of entry and in Asian community shops around the country. “We are trying to recognize products that have levels we are really concerned(worried) about, rather than trying to find the last molecule,” said Sundlof.
67. The underlined word “minuscule” in Paragraph 6 means __________.
A. very small B. acceptable C. worried D. large
68. According to FDA, people in America needn’t be worried if _________.
A. food is infected with melamine below a level of 2.5 parts per million
B. baby formula contains no melamine
C. they buy candies for babies produced locally
D. foods imported from China are recalled
69. It can be inferred from the passage that _________.
A. America won’t import foods from China any more
B. America is still importing foods from China
C. manufactures do not use any ingredients from China for baby formula
D. all foods imported from China contain melamine
70. The passage is probably found in _________ section on the Internet.
A. News Reports B. International Trade

Endless playing of songs like All I want for Christmas in shops during the festive season doesn’t just drive us mad —the songs also make us more careless with our money, research has warned．
While repeated performance of Jingle Bells may seem like an innocent attempt to raise customers’ spirits during the nightmare of Christmas shopping, the songs also have a more delicate impact．
“Background music, or “Muzak”, can be used by marketers to impose cultures ---such as the commercialization of Christmas--- onto consumers and influence their behaviour,” experts said．
Dr．Alan Bradshaw of Royal Holloway, University of London, said, “Festive jingles are force-fed to Christmas shoppers in a bid to change their mood, influence their sense of time and what sort of products they buy．In other words, this is an attempt to control your shopping habits in a way that you might hardly be aware of．”
“Often we are told that we have the freedom to choose where we want to shop, but during Christmas the use of music in this way is so common that our freedom to choose disappears．”
Dr．Bradshaw and Prof Morris Holbrook of Columbia University examined the phenomenon and found that retailers often “dumb down” the music played in shops to relax customers, meaning it is easier to control their behaviour．
It is thought that slowing down the rhythm of music in shops can trick customers into thinking less time has passed, and therefore spend more time examining the shelves, for example．
Some providers of background music have been known to promote their services by claiming they can boost profits by controlling the behaviour of customers．
“A common trick is to take a popular current song and record an instrumental version which can be slowed down or sped up at different time of the day to influence behaviour in different ways,” Dr．Bradshaw said．
Background music is often classed as “Muzak” in honor of the Seattle-based company which began producing its soft-sounding melodies in the 1930s．According to Dr．Bradshaw, in what ways does Christmas music influence customers?
①their mood
②their income
③their sense of time
④ the sort of products they buy
| A．①②③ | B．①③④ | C．②③④ | D．①②④ |
Shopkeepers slow down the rhythm of music in shops to ___________．
| A．let customers spend more time shopping |
| B．make customers and sales assistants relaxed |
| C．let customers enjoy the beautiful music |
| D．help customers find what they really want |
What kind of music is now often adapted to influence customers in shops?
| A．Classical music | B．Popular modern songs． |
| C．Folk songs． | D．Jazz music． |
What is the best title of the passage?
| A．Music makes happy Christmas |
| B．Christmas “Muzak” |
| C．How to make Christmas music? |
| D．Christmas music makes us spend more |
When policy experts debate climate change solutions, they often talk about "a price on carbon." They are arguing about whether companies should pay when they put carbon pollution in the air. Proponents say that it's simple economics -- if it's free to pollute, you'll get a lot of pollution. Opponents claim it will raise the cost of energy that's produced from high carbon sources, like coal. But here's the secret that most people seem to be missing: There already is a price on carbon, and it's paid by the taxpayers.
Carbon pollution, like every other form of pollution, has an impact on the environment. Throwing waste into a river will cause the fish to die and the people who drink the water to get sick. And when you produce carbon pollution, you get climate change -- sea level rise, stronger storms, severe droughts, damage to agriculture, and more.
All of those impacts cost money. Insurance rates go up when storms get more destructive. Taxes increase when cities have to rebuild bridges and roads. Military budgets go up when droughts and population changes cause conflicts. Not to mention impacts on agriculture and health care costs.
In other words, the price on carbon is what we all pay when there is no market force to limit the pollution that causes climate change. So the debate is really about who will pay that price -- the companies who are making a profit from the fossil fuels, or the taxpayers who pick up the cost now?
Right now, we have private profit and public cost. It's just like if we allowed every business to throw its garbage in the street because it's too expensive to have it moved away properly. Does it add a little bit to your dinner check to require that restaurants dispose of their trash properly? Sure. But it would be more expensive for you if the city had to clean the streets of their garbage every day. So just like we put a "price on garbage" we need a "price on carbon pollution."
Now, a "price on carbon pollution" can mean a lot of things. You could tax companies based on the amount of carbon pollution they produce, and return the money to taxpayers. You could put a limit on how much they can produce, thereby requiring them to invest in ways to conduct business in a less polluting way.What do the policy experts argue about carbon pollution?
| A．Whether the companies should pay for it. |
| B．Whether taxpayers could get profit from it. |
| C．Who have the ability to change it. |
| D．How much should be paid for it. |
What’s the main idea of Paragraph 2 ?
| A．Some other forms of pollution |
| B．The effects of carbon pollution |
| C．The signs of carbon pollution |
| D．The way to reduce carbon pollution |

| A．prove every business doesn’t perform its duty. |
| B．warn readers to protect the environment around. |
| C．explain the damage of no policy on carbon pollution. |
| D．show some restaurants throw away their trash randomly. |
According to the passage, what does the “price on carbon pollution” means?
| A．Telling the taxpayers to refuse to pay taxes on carbon pollution |
| B．Making the government invest to reduce carbon pollution |
| C．Increasing prices of the products from companies. |
| D．Taxing companies on carbon pollution they produce. |
New research has shown that loneliness may affect ants to a greater extent than many other living creatures.
It has long been known that loneliness can lead to a shorter life. In humans, it has even been found to be a driver of high blood pressure, sleep disorder, and depression that’s independent of factors like age, race, gender, weight and economic status.
However, loneliness has never been identified as a factor that can cut human lifespan by more than a small part of the average. Ants, on the other hand, appear to be far more sensitive to this stress, with loneliness leading to a surprising 91 percent reduction in lifespan.
That’s at least according to a study that details how “lonely” ants only live up to six days on average. Ants living in a community, on the other hand, were found to live up to about 66 days.
In a series of experiments where ants were picked from their colonies (群体) and separated, they were found to continuously walk without rest,consuming far more energy than they could ever.
The reason for the behavior is that an isolated ant is simple trying to get back to its colony at all costs, and doesn’t know what to do without its nest mates. After all, many entomologists (昆虫学家) would argue that an ant colony is far more a single living entity (实体) than its members.
If you were to take a single part from a clock, it would simply move aimlessly as well, running without a purpose. However, while there is a difference between aimlessness and loneliness, the researchers found that the latter affects lonely ants more directly.
The study indicated that ants can’t even eat alone, as they normally collect some of the food they gather in the field in a specialized organ called a crop.This crop is normally shared with other ants back at a nest,but as for a single ant, it simply just sits there, undigested and useless.How does loneliness influence a person?
| A．It can make him very tired of himself. |
| B．It can leave him in conflict with others. |
| C．It can lead to him being very independent. |
| D．It can cause him to suffer from poor health |
What can be learned from the experiments?
| A．Most ants can live about 6 days on average. |
| B．Lonely ants can become very restless. |
| C．Human beings are similar to ants in some way. |
| D．Lonely ants seem to be violent and impatient. |
Why does an isolated ant walk non-stop?
| A．It attempts to return to its colony. |
| B．It wants to attract other ants to form a colony. |
| C．It hopes to make signals to its mates. |
| D．It has to find more food to survive. |
The author mentioned a clock in the passage_________.
| A．to show ants have a biological clock in the head. |
| B．to prove ants are a well-regulated community. |
| C．to stress ants are really highly social animals. |
| D．to compare aimlessness with loneliness. |

Certainly, a well-rounded education is the foundation from which all of us spring forth. I am grateful to the many incredible teachers who have inspired me to do greater things, and have fired my enthusiasm for everlasting learning!
I have also been honored to have the most amazing teachers in all of my children’ s lives. These are extraordinary people who not only teach our children, but love them, inspire them, and provide an environment where a child learns how to learn.
But, sometimes I wonder if the outline of our educational plan is lacking something. I watched the movie Easy A with my older daughter. The main character’ s parents were loving, supportive, and built great confidence in their daughter and developed her ability to handle her own problems.
There was a scene where the mother was speaking to the younger child and he announced that he received an “ A” on his spelling test. She replied, “ That’s great, honey, but everything has spell check these days. ”It was funny — but TRUE!I don’t mean that we shouldn’t teach our children how to spell, but maybe some of our time should be spent educating them about the dangers of posting things on Facebook.
Maybe we might want to spend time showing them how real life works— the credit card isn’t free money— you will have to pay it back at sometime. Oh, and get this—they charge you for borrowing that money. Perhaps, we should spend some time on interpersonal relationships. I worry that our kids do not know how to relate to one another.
Choosing a career is a daunting task. My daughter is in her second year in college and has changed her major twice. It’s not that she didn’t know what she wanted to do. What she “ wanted to do”and the degree she chose did not match.
I have learned many college students do not know what they want to do because they haven’t seen what it looks like in the real world. Being a journalist in the real world looks very different from writing stories. Maybe if we spent some time exposing them to real life experience— maybe two or three courses in areas of interest in high school that give them a “ feel ” for what that particular field would look like, they might be better prepared. I do not know the solution, but it seems that it should at least be a topic of discussion.Why does the author mention the movie Easy A?
| A．To prove the importance of book learning. |
| B．To lead to the topic he is going to talk about. |

| A．students need to focus on the skills in learning |
| B．parents and school should be consistent in education |
| C．his daughter is smart enough to make her own choice |
| D．courses in areas of interest in high schools will benefit students |
