In a national spelling contest in America, an 11-year-old girl was asked to spell a certain word. But with her soft voice the judges were not sure if she spelled the word with the letter A or E. __1__ At that time, the girl knew she had misspelled the word. But instead of lying and telling the judges she had said the correct letter, she told the truth that she had said the wrong letter. __2__.

As the girl walked off the stage, the entire audience stood on their feet clapping to applaud her honesty. Later, dozens of newspaper wrote about this 11-year-old girl’s courage and honesty, even when it cost her the contest. __3__

Probably the biggest test of our character and honesty is what we would do if we knew we would never get caught.

This young girl could easily have lied, and nobody would have known it but her. But that’s just it: She would know she did wrong. __4__

This young girl was strong and smart enough to prize her own conscience and character more than the prize from a spelling contest. Her respect for herself was more important than any respect others might give her for winning a contest. She knew she would have to live with herself and the choice she made at the moment.

__5__

E. It’s so true that the choices you make today make what you are tomorrow.

F. They talked it over and finally decided to simply ask her what she had said.

G. But the fact is that she won the biggest contest that day: the contest of her character.

We might like to think we're not influenced by other people, but a new study into the group-buying mechanisms（机制） - like those used on coupon（优惠券） sites such as Groupon and LivingSocial - reveals that telling buyers who come later to the offer how many have already signed up increases the number of purchasers.

Researchers at the University of Toronto's Rotman School of Management wanted to understand why group buying sites that have entered the market recently have enjoyed greater success than those operating a decade ago, such as Mercata and MobShop.

Earlier attempts typically left potential buyers waiting for days before confirming whether or not they had got the offer they had signed up for.

“We think one of the reasons group-buying has been successful recently is because of the short time horizon,” says Rotman Professor Ming Hu, who co-wrote the study with Professor Mengze Shi and PhD student Jiahua Wu. “It allows for a herding effect.”

Another reason is the use of an information structure that discloses to later arrivals how many have already signed onto the deal.

Researchers looked at two ways of designing the purchasing mechanism for a group buy:a simultaneous mechanism, where no one knows how many buyers have come before them, and asequential（连续的） mechanism, where a second group of buyers has the advantage of knowing the size of the first group.

The researchers' analytical（分析的） model shows the most successful mechanism is the sequential one because it eliminates uncertainty for those coming later to the deal, and improves the confidence of those who sign on early, as they're able to track the numbers of those who come after them.

“That boosts confidence,” says Professor Hu, who teaches operations management. Deals for "luxury" services, versus everyday items, work better in a group buy scenario（方案） because they offer consumers a greater benefit.

1.It can be learned from the text that ______.

2.The underlined word “eliminates” in paragraph 7 probably means“______”.

3.What can be the best title for the passage?

Mobile phones are an important business tool for farmers in rural areas. But they also put a valuable educational tool in their hands.

The University of Illinois in the United States has a project called SAWBO—Scientific Animations Without Borders. It produces educational videos that can be downloaded to cell phones. The goal is to help people in developing countries improve their lives.

One video shows farmers how to make a natural insecticide from neem seeds to prevent insect damage to crops. The process starts with sorting and drying the neem fruits. Then let the fruit dry in the sun for about three or four days, until they become brown. Using a mortar(碾槌) and stick, the fruits are slightly pounded to remove the shells from the fruits without breaking the seed inside.

The videos use computer animation(动画). Some of the animated characters are a little funny looking-like a farmer with a long nose. But the subjects are serious, including a health video on preventing cholera(霍乱). Team member Francisco Seufferheld says the information in the videos is meant to be quickly understood. He says, “The information is digested in such a way that in two minutes, we can transmit a complex idea.”

The researchers tested the seven-minute video on seven mobile phones. They wanted to see if people would share the video using Bluetooth wireless technology. With Bluetooth, files can be passed to a nearby phone even if neither phone is connected to the Internet. As a result, in one month, the video had spread to one hundred eighteen people in fifty different villages. “This is just incredible impact,” said Francisco Seufferheld.

The team has made a few videos so far. These are available in a total of eighty languages, dialects and accents. Professor Barry Pittendrigh says there are plans for more videos later this year.

1.What is the text mainly about?

2.The SAWBO program is introduced in order to ____.

3.The biggest advantage of the program is that it______.

4.Which of the following words can best take the place of the word “ pound” in the 3^rd paragraph?

They may be small and not able to speak, but babies are proving their amazing cleverness. Scientists began finding infants’ skills are more than they are supposed to be.

_________

Speaking of music, babies can’t seem to resist it. Not only are their ears turned to the beats, babies can actually dance to the music.

To test babies’ dancing ability, the researchers played recordings of classical music, rhythmic beats and speech to infants, and recorded the results. They also invited professional dancers to analyze how well the babies matched their movements to the music. The babies moved their arms, hands, legs feet and heads in response to the music, much more than to the speech. The finding suggests this dancing ability is innate(与生俱来的) in humans, though the researchers aren’t sure why it becomes weaker later in their life.

Learning Quickly while Sleeping

Babies can learn even while asleep, according to a 2011 study. In experiments with 26 sleeping infants, each just 1 to 2 days old, scientists played a musical tone followed by a puff of air to their eyes 200 times over the course of a half-hour. 124 electrodes(电极) stuck on the head and face of each baby recorded brain activity during the experiments. The babies rapidly learned to foretell a puff of air upon hearing the tone, showing a four-time increase on average in the chances of tightening their eyelids in response to the sound by the end of the experiments.

As newborns spend most of their time asleep, this newfound ability might be crucial to rapidly adapting to the world around them and help to ensure their survival, researchers said.

Judging Characters Well

Judging another person helpful or harmful is crucial when choosing friends. And that ability starts early. Kiley Hamlin of Yale University showed both 6-and 10-month-olds a puppet(木偶) show, in which one character helped another climb a hill. In another scene a third character pushed the climber down. The little ones then got to choose which character they preferred. For both age groups, most babies chose the helper character. This character-judging ability could be baby’s first step in the formation of morals, Hamlin thought.

1.Which of the following subtitles can fill in the underlined blank?

2.The underlined word “it” in the third paragraph refers to______.

3.The experiment with 26 sleeping infants prove that_______.

4.In the last experiment, most babies chose the helper character, showing that________.

Joey is loyal, encouraging and self-sacrificing, always putting others’ interests ahead of his own. He is a hard worker, who also loves to run and play. In short, he’s an ideal friend and a heroic character.

Here is the thing: Joey is a horse, who appears as the main character in Steven Spielberg’s new film War Horse.

It is based on Michael Morpurgo’s 1982 novel, which also caused the same-titled Tony Awards winning play.

The film follows the saga of Joey, a racehorse that’s trained for farm work under the loving care of Albert (Jeremy Irvine )after Albert’s drunk father Ted(Peter Mullan ) overpays for the animal at auction(拍卖会).

Then the World War I tears Albert and Joey apart. Joey is sold into the war effort for the British and starts his episodic adventures in Europe.

Splendidly staged, the battle plots in the film are visually astounding and impressive.

And with Spielberg’s unique, top-notch direction and storytelling skills, War Horse cannot escape its episodic nature, calling to mind another Spielberg film about the horrors of war and its effects upon soldiers and civilians—Saving Private Ryan.

While that film shocked with horrific scenes of bleeding, it relied on a company of easily-described characters and a focused storyline to present heroic themes.

Like Saving Private Ryan, War Horse clings to a series of characters, not only Albert, but also British officers, French civilians and German soldiers, who display courage in the face of danger. Everyone who comes in contact with Joey is either already in touch with their inner angel or is quickly moved to become more humane.

Although none of this covers the fact that we’ve seen this stuff elsewhere before, the lovely sentiment will steal your heart.

And the emotional signature of Spielberg can be felt as he establishes the relationship between the boy and the horse and the mood of the piece – there will be tears.

Therefore, calling this beautiful, dramatically incomplete film “ Saving Private Joey”, is entirely justifiable.

1.In common with “ Saving Private Ryan”, the film War Horse _________ .

2.Which statement is true according to the passage?

3.According to the passage, what does the underlined word astounding mean?

4.What is the best title for the passage?
