Can you believe your eyes? A recent experiment suggests that the answer to that question may depend on your age.
Martin Doherty, a psychologist at the University of Stirling in Scotland, led the team of scientists. In this experiment, Doherty and his team tested the perception(观察力) of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25.
The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 percent of the time. Adults identified the correct circle 95 percent of the time.
Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by gray circles. Here's where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller gray circles —making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger gray circles—so it appeared to be smaller than the real smaller orange circle.
When young children aged 4 to 6 looked at these tricky pictures, they weren't fooled—they were still able to find the bigger circle with roughly the same accuracy as before. Older children and adults, on the other hand, did not do as well. Older children often identified the smaller circle as the larger one, and adults got it wrong most of the time.
As children get older, Doherty said, their brains may develop the ability to identify visual context. In other words, they will begin to process the whole picture at once: the tricky gray circles, as well as the orange circle in the middle. As a result, they're more likely to fall for this kind of visual trick.Why are younger children not fooled?_____________.
| A．Because their brain can hardly notice related things together. |
| B．Because older people are influenced by their experience. |
| C．Because people's eyes become weaker as they grow older. |
| D．Because they are smarter than older children and adults. |
Doherty and his team of scientists did an experiment to evaluate_____________.
| A．children's and adults' eye-sight |
| B．people's ability to see accurately |
| C．children's and adults' brains |

When asked to find the larger circle,_____________.
| A．children at 6 got it wrong 79 % of the time with no gray ones around |
| B．only adults over 18 got it right 95% of the time with gray ones around |
| C．children at 4 got it right about 79 % of the time with gray ones around |
| D．adults got it right most of the time with gray ones around |
According to the passage, we can know that_____________.
| A．a smaller orange circle appears bigger on a white background |
| B．an orange circle appears bigger than a gray one of the same size |
| C．a circle surrounded by other circles looks bigger than its real size |
| D．a circle surrounded by bigger ones looks smaller than its real size |
Burns can be caused by fire, the sun, chemicals, heated objects or fluids, and electricity. They can be minor problems or life-threatening emergencies. Distinguishing a minor burn from a more serious burn involves determining the degree of damage to the tissues of the body. If you are not sure how serious the burn is, seek emergency medical help.
First-degree burns are those in which only the outer layer of skin is burned. The skin is usually red and some swelling (肿大) and pain may occur. Unless the burn involves large portions of the body, it can be treated at home.
Second-degree burns are those in which the first layer of skin has been burned through and the second layer of skin is also burned. In these burns, the skin reddens intensely and blisters (水泡) develop. Severe pain and swelling also occur. Second-degree burns require medical treatment.
Third-degree burns are the most serious and involve all layers of skin. Fat, nerves, muscles, and even bones may be affected. Areas may be charred black or appear a dry white. If nerve damage is substantial, there may be no pain at all. These burns require emergency medical attention.
Follow these steps when treating minor burns at home:
1) If the skin is not broken, run cool water over the burn for several minutes.
2) Cover the burn with a sterile (消过毒的) bandage or clean cloth.
3) Take aspirin to relieve any swelling or pain.
Seek emergency treatment immediately for major burns. Before an emergency unit arrives, follow these steps:
1) Remove the person from the source of the burn (fire, electrical current, etc.).
2) If the person is not breathing, begin mouth-to-mouth resuscitation (人工呼吸) immediately.
3) Remove all clothing to stop further burning. If the clothing is stuck to the burn, do not attempt to remove it.
4) Cover the burned area with a cool, moist, sterile banda
ge or clean cloth. Do not place any creams, ointments (药膏) or ice on the burned area or break blisters.
5) Monitor the patient for signs of shock, and treat accordingly. The underlined sentence in the first paragraph probably means “______”.
A. They can be dangerous if you don’t treat them seriously
Ｂ. They range from slight burns to deadly ones
C. They seldom cause deaths even if not treated properly
D. They usually cause deaths if not treated properlyBurns are divided into different degrees according to _______.
| A．what kind of treatment they need |
| B．what kind of tissue of the body is damaged |
| C．whether there is pain and what degree of pain there is |
| D．which layer of skin is burned |
From the passage we learn that ___
____.
| A．if there is severe pain, then you need medical treatment |
| B．first-degree burns don’t require medical treatment |
| C．burns without pains can be treated at home |
| D．the larger the swelling is, the more serious it is |
It can be inferred from the passage that ______
.
| A．you shouldn’t cover the burn with a bandage or cloth if it is severe |
| B．you shouldn’t move the person unless you know how to do first aid |
| C．you shouldn’t run cool water over the burn if the skin is broken |
| D．you shouldn’t place any wet towels on the burned area |
where do you probably find the passage?
| A．a fashion magazine | B．a guide book |

Many of us already know about several American superstitions（迷信）. Having a black cat cross your path, walking under a ladder, and breaking a mirror are all bad luck. In addition, there are many other superstitions that are worth knowing. Understanding them will keep you safe from evil spirits —if you believe in such things —and impress your American friends when you mention them.
Like the superstitions in other cultures, American superstitions often involve the things important in daily life, such as health, numbers, and marriage. For example, have you ever had a cough that would not go away? According to one Amer
ican superstit
ion, you should take a piece of your hair and put it between two slices of buttered bread. Next, feed this hair sandwich to a dog and say, “Eat well, you hound, may you be sick and I be sound.” This will trick the evil spirits and help your cough. It will also raise some eyebrows if you try it.
In American superstitions, the number three is very important. Often, Americas will say, “All things come in threes.” Three is lucky because it represents the traditional family: mother, father, and child. Therefore, gifts, letters, and guests will often arrive at your home in groups of three. However, it is also possible for bad events, like accidents and funerals, to come in threes as well.
Another time peopl
e pay attention to superstitions is when they get married. During a wedding, brides must wear or carry “something old, something new, something borrowed, and something blue”. The old and borrowed things will bring luck to the person who gives them to the bride. The new and blue things wi
ll bring good fortune to the bride herself. The next time someone you know is getting married, be sure to recite this phrase.
As it would be unlucky to discuss one more superstition, we will wind things up here. Keep your fingers crossed, and stay lucky!The passage is most probably entitled .
| A．American’s Bad Luck | B．Cross-culture and Superstitions |
| C．American Superstitions | D．Daily Life in Superstitions |
The underlined sentence in the second paragraph “It will also raise some eyebrows if you try it.” means .
| A．when you try it, the dog will raise its eyebrows. |
| B．you will make people surprised when you try this trick |
| C．only if you raise your eyebrows can the trick work |
| D．you will believe in the trick after you try it |
In American’s view, the number three is a(n) number.
| A．lucky | B．unlucky | C．special | D．ordinary |
On the wedding, the bride often uses old and borrowed things so as to .
| A．save some money for the wedding |
| B．bring good luck to the people who give them to the bride |
| C．give the good luck to the bride herself |
| D．pass the bad luck to others |
After reading the passage, we may feel it is written in a tone.
| A．formal | B．serious | C．humorous | D．critical |
In white shirt, blue pants, black cloth shoes and two pigtails (辫子), Jingqiu gives off an air of great “pure beauty” in Zhang Yimou’s new movie Under the Hawthom Tree.《山揸树之恋》
The film tells the story of the sad romance of Jingqiu and a handsome young man named Laosan. Set at the end of the “cultural revolution” (1966-1976), the pair manage to fall in love although they come form different political environments.
Before it was released, moviegoers speculated (推测) on just what this “pure beauty” could be. Director Zhang complained of how long it had taken him to find the right girl for the part of Jingqiu—a character so innocent that she believes simply lying on the same bed with a man will make her pregnant.
It was 18-year-old Zhou Dongyu who stood out from the crowd. According to Zhang, Zhou has “eyes that are clear like a fountain on a mountainside”. Born of an ordinary worker’s family, the Shijiazhuang girl was in her final year of high school and working hard for a place in an art college.
While some teenagers co
nsider such “pure beauty” illusory (虚幻的), others believe that it speaks of something soulful.
Purity is all about the innocence that shines through from within, thinks 16-year-old Tan Mengxi of Nanjing.
“Being pure can be simple, not having complicated thoughts and being inexperienced. However, it doesn’t mean an ignorant or naive (天真的) person. So, a person is pure in his or her nature if he or she is always enthusiastic and able to deal with difficult matters independently. This purity doesn’t pass with time,” she said. What image does Jingqiu give to audiences in the movie Under the Hawthorn Tree?
| A．A simple girl. | B．A pure girl. | C．A romantic girl. | D．A silent girl. |
What kind of girl looks pure according to the passage?
| A．A girl in red shirt, blue pants, black leather shoes and two pigtails. |
| B．A girl has eyes that are clear like a fountain on a mountainside. |
| C．A girl who was born into an ordinary worker’s family. |
| D．A girl wears accessories and make-up. |
What’s the opinion of Tan Mengxi about purity?
| A．It is of whether someone is ignorant or naive. |
| B．Being pure can be simple, not having complicated thoughts and being inexperienced. |
| C．It is of whether someone is always enthusiastic. |
| D．Purity is a matter of internal quality and doesn’t pass with time. |

THIS was the year the Earth struck back.
Earthquakes, heat waves, floods, volcanoes, super typhoons, snow storms, landslides and droughts killed at least a quarter of a million people in 2010 – the deadliest year in more than a generation. More people were killed worldwide by natural disasters this year than have been killed in terrorism attacks in the past 40 years combined.
"It just seemed like it was back-to-back and it came in waves," said Craig Fugate, who heads the U.S. Federal Emergency Management Agency. It handled a record number of disasters in 2010.
And we have ourselves to blame most of the time, scientists and disaster experts say.
Even though many catastrophes have the ring of random chance, the hand of man made this a particularly deadly, costly, extreme and weird（古怪的） year for everything from wild weather to earthquakes.
Poor construction and development practices conspire to make earthquakes more deadly than they need be. More people live in poverty in vulnerable（脆弱的） buildings in crowded cities. That means that when the ground shakes, the river breaches, or the tropical cyclone hits, more people die.
Disasters from the Earth, such as earthquakes and volcanoes "are pretty much constant," said Andreas Schraft, vice president of catastrophic perils for the Geneva-based insurance giant Swiss Re. "All the change that's made is man-made."
The January earthquake that killed well more than 220,000 people in Haiti is a perfect example. Port-au-Prince has nearly three times as many people - many of them living in poverty - and more poorly built shanties than it did 25 years ago. So had the same quake hit in 1985 instead of 2010, total deaths would have probably been in the 80,000 range, said Richard Olson, director of disaster risk reduction at Florida International University.
In February, an earthquake that was more than 500 times stronger than the one that struck Haiti hit an area of Chile that was less populated, better constructed, and not as poor. Chile's bigger quake caused fewer than 1,000 deaths.
Climate scientists say Earth's climate also is changing, bringing extreme weather, such as heat waves and flooding.
In the summer, one weather system caused oppressive heat in Russia, while farther south it caused flooding in Pakistan that inundated 161,200 square kilometers, about the size of Wisconsin. That single heat-and-storm system killed almost 17,000 people, more people than all the worldwide airplane crashes in the past 15 years.
Scientists have calculated that the killer Russian heat wave—setting a national record of 43.9℃—would happen once every 100,000 years without global warming.What is responsible for the most human deaths in 2010?
| A．Natrual disasters. | B．Terrorist attacks. |
| C．Poor buildings. | D．Too rapid developrnent. |
According to Andreas Schraft, .
| A．earthquakes are happening more often because of human beings |
| B．earthquakes are causing more damage because of human beings |
| C．stronger houses should be built to limit storm damage |
| D．Port—au—Prince is now overpopulated |
The main point of the article is to
| A．list the natural disasters that occurred in 2010 |
| B．give the details of some natural disasters of 2010 |
| C．warn that more natural disasters are to strike |
| D．blame humanity for not helping those affected by the disasters |
Each time I see a balloon, my mind flies back to a memory of when I was a six-year-old girl. It was a rainy Sunday and my father had recently died. I asked my mom if Dad had gone to heaven. "Yes, honey. Of course." she said.
"Can we write him a letter?"
She paused, the longest pause of my short life, and answered, "Yes."
My heart jumped. "How? Does the mailman go there?" I asked.
"No, but I have an idea." Mom drove to a party store and returned with a red balloon. I asked her what it was for.
"Just wait, honey. You'll see." Mom told me to write my letter. Eagerly, I got my favorite pen, and poured out my six-year-old heart in the form of blue ink. I wrote about my day, what I learned at school, how Mom was doing, and even about what happened in a story I had read. For a few minutes it was as if Dad were still alive. I gave the letter to Mom. She read it over, and a smile crossed her face.
She made a hole in the corner of the letter where she looped (缠绕) the balloon string. We went outside and she gave me the balloon. It was still raining.
"Okay, on the count of three, let go. One, two, three."
The balloon, carrying my letter, darted upward against the rain. We watched until it was swallowed by the mass of clouds.
Later I realized, like the balloon, that Dad had never let his sickness get him down. He was strong. No matter what he suffered, he'd persevere, dart up, and finally transcend (超越) this cold world and his sick body. He rose into sky and became something beautiful. I watched until the balloon disappeared into the gray and white and I prayed that his strength was hereditar. I prayed to be a balloon.When the girl asked her mother if they could write to her father, her mother _________.
