It is the first report that home-grown food has been contaminated by radioactivity, largely Iodine(碘)-131, since the ministry ordered radiation( powerful and harmful rays that are sent out from radioactive substances) tests on food and water at the end of March in 14 mainland regions including Beijing, Tianjin, and some coastal provinces.
Sample inspections conducted on Tuesday found low levels of radioactive iodine in spinach( a kind of green vegetables) planted in Beijing, Tianjin and Henan province --- about 1-3 becquerels per kilogram (Bq/kg), the statement said.
"The contamination level detected is too low to be harmful to public health," it said.
According to health experts, radioactive iodine can accumulate in humans once ingested in high concentrations and increases the risk of thyroid cancer. But it decays naturally within weeks.
Leafy vegetables grown in the open like spinach, lettuce and leek are among the first foods to be tainted by radioactive deposits.
Raw milk is also susceptible to radioactive contamination as livestock feed on grass.
Tests carried out in March showed spinach and milk taken from farms near Japan's nuclear-stricken area had exceeded(go beyond) government-set safety limits for radiation.
No cases of tainted water or milk have been reported in China but the ministry vowed to further strengthen monitoring.
Wang Zhongwen, a researcher at the China Institute of Atomic Energy's radiation safety department, told China Daily on Wednesday that currently China only had the means to conduct food radiation tests in a few regions.
The statement also said that recent rain in Beijing and Tianjin meant radioactive substances could have fallen on vegetables.
Chen Jicang, a vegetable dealer in Beijing, said on Wednesday that concerns are growing among consumers, businesses and governments across the world.
"We have yet to see any impact on our business from the radiation, but we will keep a close eye on how the issue develops," he said.
He added that most vegetables consumed in Beijing are produced locally, and he might switch to other varieties if spinach sales suffer.
Yang Guoshan, a researcher of radiation medical science at the Academy of Military Medical Sciences, said people could safely eat products that contain low levels of Iodine-131.
"The radiation level is so low that residents don't need to spend any extra effort on cleaning them," he said.
Gao Jie, a 52-year-old resident in Tianjin said she is deeply worried because spinach is a staple part of her family's diet.
"If spinach is radioactive, is there any possibility that other types of vegetables are safe?"
Trace levels of radioactive isotope cesium-137 and -134 were detected in the air in 21 provinces and regions on Wednesday, up from 17 on Tuesday, according to China's National Nuclear Emergency Coordination Committee.

Why did the chicken cross the road? To get to the other side.
Most people know this joke. But recently, some people have been much more worried about how the grizzly bear and mountain lion can cross the road.
“Millions of animals die each year on U.S. roads,” the Federal Highway Administration reports. In fact, only about 80 ocelots, an endangered wild cat, exist in the U.S. today. The main reason? Roadkill.
“Eco-passages” may help animals cross the road without being hit by cars. They are paths both over and under roads. “These eco-passages can be extremely useful, so that wildlife can avoid road accidents,” said Jodi Hilty of the Wildlife Protection Society.
But do animals actually use the eco-passages?  The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an eco-passage that went under a highway.  This showed that the lions used the passage.
Builders of eco-passages try to make them look like a natural part of an area by planting trees on and around them. Animals seem to be catching on. Animals as different as salamanders(火蜥蜴)and grizzly bears are using the bridges and underpasses.
The next time you visit a park or drive through an area with a lot of wildlife, look around.  You might see an animal overpass!
小题1: The writer uses the example of “ocelots” to show that __________.
A.wild animals have become more dangerous
B.the driving condition has improved greatly
C.an increasing number of animals are killed in road accidents
D.the measure for protecting wildlife fails to work
小题2:From the story, we know an eco-passage is __________.

小题3: When the writer says that “animals seem to be catching on” (Para. 6), he means __________.
A.animals begin to realize the dangers on the road
B.animals are crossing the road in groups
C.animals are increasing in number
D.animals begin to learn to use eco-passages
小题4: The writer asks visitors and drivers to look around when traveling because __________.
A.wild animals may attack carsB.they may see wild animals on eco-passages
C.they may see wild animals in the parkD.wild animals may jam the road
小题5: The best title for the passage is __________.
A.Special bridges help animals cross the road

Knowing the best way to study will help you to be a better student. By using your time properly, you can do your homework more quickly. Learning to study is not difficult.
The first thing to remember is that you must be willing to learn. It doesn’t mean that you must always like the subject. It does mean, however, that you must be wil1ing to do whatever is necessary to learn. Try to understand why it is important and how it will help you now and later to do and learn other things. Knowing mathematics facts will be useful in your whole life. Knowing how to spell makes any kind of writing easier. Sometimes the subject that you think is going to be uninteresting will be exciting when you begin to work at it and understand it more clearly. Learning things can be fun if you are willing to work with them.
Here’s some advice for you: have a certain time each day and a quiet place with good lighting for study, so that you can concentrate on your study without interruptions(中断); have everything ready before you sit down to study, a dictionary, paper, a pen and books; be sure you understand what you should learn before you start; read carefully and pay special attention to the most important things; when memorizing, first find out the main parts and then recite the whole thing; check your homework after you finish it; never forget the importance of review and preview.
Don’t try to spend a lot of time researching learning methods. There are many students who know many good learning methods but don’t study well. They forget that the most useful learning method is to study hard.

Britain’s seed bank, the only one in the world aiming to collect all of the planet’s wild plant species, has reached its goal of banking 10 percent by 2010.
The Millennium Seed Bank Project, run by Kew Gardens—one of the oldest botanical gardens—will officially deposit the 24,200th species on Thursday, a pink, wild banana from China.
More than 50 countries are now on board with Kew's giant task but vast places of the globe, including India and Brazil, still need to join in and donate seeds, director Paul Smith said.                                                                                                                                                            
The seed bank is one of the largest and most diverse in the world with more than 1.5 billion seeds. Its goal is to help protect the planet’s bio-diversity during a time of climate change.
The wild banana seed is under threat of extinction(灭绝) in southwest China from agricultural development. It is a vital food source for Asian elephants and important for growing bananas for human consumption.
Stored at minus-20 degrees centigrade, so they can last for thousands of years, the seeds await the day that scientists hope never comes—when the species no longer exist in the wild.
It is a race against time, Smith said, because in the last decade alone, 20 plants held in the bank have already been wiped out in the wild. He estimates that between a third and a quarter will become extinct this century.
"It is urgent and it is happening now. An area, the size of England, is cleared of primary vegetation(植被)every year." Smith said.
Because most of the world's food and medicines come from nature, protecting wild plant species is quite important, scientists say. There are already many other seed banks safeguarding food crops, which only account for 0.6 percent of plant diversity.
For Kew's next goal—to collect a quarter of wild varieties by 2020—the botanists need 10 million pounds a year, or a further 100 million pounds on top of the 40 million they have already been granted.
小题1:What’s the final purpose of the Britain’s seed bank?
A.To collect enough money for the project.B.To safeguard food crops.
C.To protect wild plants from extinction.D.To help scientists study wild plants.
小题2:The wild banana seed in China is in danger because of _______.
A.the expanding of farming workB.the climate change in this area
C.the large number of Asian elephantsD.human’s large consumption
小题3: We can learn from the passage that _______.
A.the seeds in the bank can be used now and then all over the world
B.India and Brazil haven’t joined in the Seed Bank Project at present
C.there is only one seed bank in the world at present
D.the wild plants in places like India and China will never die out
小题4: What does the underlined word “it” in paragraph 7 refer to?
A.The extinction of plant species.B.The Millennium Seed Bank Project.
C.Britain’s seed bank.D.Kew Gardens’ next goal.
小题5:Which of the following information isn’t mentioned in the passage?
A.The global partnership of collecting wild plant species.
B.The temperature condition of the conservative wild plant species.
C.The government’s financial support for the seed bank project.
D.Scientists’ concern on the extinct wild plant species.
All sorts of items become litter(垃圾) but two of the most common and most dangerous are cigarette butts(烟头) and plastic bags. Litter is a big problem for our environment but it is a problem that individuals can easily do something about. Not littering at all or cleaning up litter, such as  cigarette butts and plastic bags, greatly improves the quality of our environment.
Although cigarette butts, are small, they are bad for the environment. Over 1,600 billion cigarette are smoked each year in China and large quantities of the butts are thrown away. Worldwide, about 4. 5 trillion butts are littered every year. Apart from the fact that butts spoil the beauty of the environment, they contain some very toxic chemicals. These find their way into the water supply where they decrease the quality of the water and endanger plants and animals that live there. So, if people have to smoke, they shouldn't throw away the butts but put them in the rubbish bin instead.
Plastic bags are another common form of litter that is a danger to the environment. There areseveral reasons for this. They are made from oil and gas, which are non—renewable resources. If they are not recycled, these resources are lost to us. In China, 2 billion plastic bags are used every day. An enormous number of these become litter. This is a huge problem because they last from 20 to 1,000 years in the environment. They float easily in the air and water and travel long distances. They find their way to rivers, parks, beaches and oceans. Plastic bags kill up to one million seabirds, 100, 000 sea mammals and countless fish each year worldwide. It is up to people not to let plastic bags become litter. It would be better if they used fewer and recycled them.
Cleaning up your cigarette butts and plastic bags would improve the environment. And we would know that we were doing something to look after our planet. However, I believe the best solution would be not to smoke or use plastic bags at all.

Three years ago I listened to a lecture on cognition (认知) that changed the way I think about intelligence. There are two types of cognition. The first is normal cognition: the ability to regain knowledge from memory. The second type of cognition is metacognition: the ability to know whether or not you know.
Does this affect intelligence? In traditional education, intelligence is measured by cognitive ability. Some people can easily produce everything they know on a test. But others are awarded with poor grades and considered inferior. But does this inability make them any less intelligent? If the question came up on a task, they could refer to a book or a quick Google search. In reality they’re just as effective as the people that ace a test. They just can’t prove it as easily.
Metacognition is more important to success than cognition. A person with poor cognitive ability, but great metacognitive ability might do poorly in school, but when faced with a challenge, they understand their abilities and take the best course of action. For example, when faced with a question, a person with strong metacognitive ability will deal with it like this. If he knows the answer, but can’t come up with it, he can always do a bit of research. If he knows for sure that he doesn’t know, then he can start educating himself. Because he’s aware of his ignorance, he doesn’t act with foolish confidence. These people might not seem intelligent at first glance, but because they know what they know, they make better decisions and learn the most important things.
However, people with great cognitive ability but poor metacognitive ability may be considered excellent at a young age for acing every test and getting great SAT scores. Unfortunately, they’ve been ruined by poor metacognition: they think they know everything but they really don’t. They are overconfident, fail to learn from mistakes, and don’t understand the slight differences of personal relationships, showing disregard for persons with lower cognitive ability. They may make the worst decisions.
The most important mental power is the ability to know what you don’t know. The recognition of a fault is the first step to improvement. Don’t try to hide a lack of knowledge. For intelligent people this is the toughest lesson to learn.
小题1:People with great cognitive ability tend to _________.
A.do well in testsB.be considered inferior
C.be more effective than othersD.do research when faced with a task
小题2:The underlined phrase “take the best course of action” probably means _________.
A.starting educating himselfB.taking action during the course
C.making the right decisionD.coming up with many ideas
小题3:People with poor metacognition may not succeed because they_________.
A.lack basic moral valuesB.have improper self-evaluation
C.fail to communicate with othersD.show little respect for others
小题4:The author probably supports the idea that _________.
A.intelligence is measured by cognitive ability
B.cognition is the most important mental power
C.the toughest lesson is to distinguish the two types of cognition
D.the awareness of one’s ignorance contributes to one’s improvement
Adult butterflies use their senses of sight, touch, hearing, smell, and taste to survive in the world, find food and mates, lay eggs in an appropriate place, migrate, and avoid hungry predators.
Sight
Butterflies have large, compound (multifaceted) eyes, which allow them to see in all directions without turning their heads. Like most insects, butterflies are very nearsighted, so they are more attracted to a large stand of flowers rather than individual plants. Butterflies do not "see" colors such as red, green, and yellow, but sense polarized(偏振的) light, which indicates the direction the sun is shining, as well as ultraviolet light, which is present on many flowers and guides butterflies to nectar (花蜜)sources.
Smell
Butterflies have a very well-developed sense of smell, but it's not in their nose (since they don't have one). Sense receptors located in their antennae, feet, and many other parts of the body help butterflies find food (usually flower nectar), and mates (the female smells the male's pheromones).
Taste
Butterfly's feet have sense organs that can taste the sugar in nectar, letting the butterfly know if something is good to eat or not. Some females also taste host plants in order to find appropriate places to lay their eggs. Adult butterflies and moths feed using a proboscis, a long, coiled tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube.
Hearing
Butterflies don't have ears. Instead they "hear" sounds through their wings by sensing changes in sound vibrations.
Butterflies may possess senses we don't even know about yet because their anatomy is very different than ours, and therefore difficult to understand when perceived through our own human senses.
小题1:From the passage we can know that butterflies can see_____
A.thing behind themB.thing in the distance
C.most bright colorsD.flower nectar from a distance
小题2: Butterflies can easily find food resources by using their______.
A.sense organs of sight and smellB.sense organs of sight and taste
C.sense organs of smell and hearingD.sense organs of smell and taste
小题3: How do butterflies feed themselves?
A.by using their feetB.by using a tube.
C.by using sense receptorsD.by using their wings.
小题4:What is the passage mainly about?
A.The food sources of butterflies.B.The habits of butterflies.
C.The unusual body of butterflies.D.the sense of butterflies.
It’s 2035. You have a job, a family and you’re about 40 years old. Welcome to your future life.     Getting ready for work, you pause in front of the mirror, “Turn red,” you say. Your shirt changes from sky blue to deep red. Tiny preprogrammed electronic(智能电子元件) is rearranged in your shirt to change its color. Looking into the mirror, you find it hard to believe that you are 40. You look much younger. With amazing advances in medicine, people in your generation may live to be 150 years old. You’re not even middle-aged.
As you go into the kitchen and prepare to pour your breakfast cereal into a bowl, you hear: “To lose weight, you shouldn’t eat that,” from your shoes. They read the tiny electronic code(电 子源码)on the cereal box to find out the nutrition details. You decide to listen to your shoes. “Kitchen, what can I have for breakfast?” A list of possible food appears on the counter as kitchen checks its food supplies.
“Ready for your trip to space?” you ask your son and daughter. In 2005 only specially trained astronauts went into space—and very few of them. Today anyone can go to space for day trip or longer vacation. Your best friend even works in space. Handing your children three strawberries each, you add, “The doctor said you need these for space travel.” Thanks to medical advice, vaccination shots(防疫针) are a thing of the past. Ordinary foods contain specific vaccines. With the berries in their mouths, the kids head for the front door.
It’s time for you to go to work. Your car checks your fingerprints and unlocks the doors. “My office. Autopilot,” you command. Your car drives itself down the road and moves smoothly into traffic on the highway. You sit back and unroll your e-newspaper. The latest news downloads and fills the viewer. Looking through the pages, you watch the news as video films rather than read it.
小题1: What changes the color of your shirt?
A.The mirror. B.The shirt itself. C.The counter. D.The medicine.
小题2: How do the shoes know that you shouldn’t eat the breakfast cereal?
A.By pouring the breakfast into a bowl.
B.By listening to the doctor’s advice.
C.By testing the food supplies in the kitchen.
D.By checking the nutrition details of the food.
小题3: The strawberries the children eat serve as ______.
A.breakfast B.lunch C.vaccines D.nutrition
小题4: How is the text organized?
A.In order of time B.In order of frequency.
C.In order of preference(偏爱).D.In order of importance
