【题目】It's 9 a.m.,the morning rush hour in Toronto.A man has fallen down on a downtown street suddenly.Several passers-by stop to help the man.One woman reaches into her purse for her cellphone and hits 911,the emergency number.【1】

Within ten minutes,the stricken man is in the back of an ambulance and is sent to the hospital for life-saving treatment.

This scene is fairly common in Toronto and other major cities.Over the years,cities have developed systems to respond quickly to emergencies.【2】But none of this would be possible without the cooperation of car drivers who yield（让路）to emergency vehicles on busy downtown streets.In fact,it's against the law for drivers not to yield.

To yield means to give away or,more specifically,to get out of the way.【3】As yet,China doesn't have any specific laws that require drivers to yield,whether it is for slower cars to move over to the inside lane of a highway or for all cars to give way to emergency vehicles.【4】Drivers did not yield when they heard the ambulance's siren.

In Canada,failing to yield to an ambulance vehicle can result in a fine of $400~$2,000 and reduction of three points off your license.That's for a first offense.

【5】This punishment is severe because lives are in danger.

A.It has resulted in many lives being saved.

B.A second offense results in a bigger fine,the loss of your driver's license for two years and a possible jail sentence.

C.It saves lives and,who knows,someday it may save your own.

【题目】【原创】Recently a series of reports appeared online in the United States and the United Kingdom lamenting(叹息) the “Lazy French”. A new labor law in France had apparently banned organizations from e-mailing their employees after 6 p.m. In fact, it turned out to be more a case of “lazy journalists” than “lazy French”: as The Economist explained, the “law” was not a law at all, but a labor agreement aimed at improving health among a group of professionals.

Brits and Americans have long suspected that the French are goofing off(吊儿郎当) while they – the good corporate soldiers—continue to toil away. They are proud about it, too. In the age of the smartphone, there’s no such things as “downtime”(停工期), and we claim that we are happier—and more productive – for it.

Are we, though? After reviewing thousands of books, articles and papers on the topic and interviewing dozens of experts in different fields, I don’t think so. When we are checking business news in bed or responding to co-workers. But, actually, we’re mostly just getting the small, easy things done. Being busy is not equal to being effective.

And let’s not forget about the surrounding play, which often distracts us from accomplishing our most important tasks. Facebook and Twitter report that their sites are most active during office hours. After all ,the employee who’s required to respond to her boss on Sunday morning will think nothing of responding to friends on Wednesday afternoon. Constant connection means that we’re “always at work”, yes, but also that we’re “never at work”—fully.

Some parts of the workforce do rely on constant connection. But others should be given proper breaks. The great technology historian, Melvin Kranzberg, said, “Technology is neither good nor bad, and nor is it neutral(中立的).” That statement should become a real principle of the information age. We must actively decide on our levels of technology engagement at different times to maximize productivity, success and happiness.

A. criticize them for how they work

B. introduce the subject of working styles

C. show the way they work

D. explain how they differ from Americans and Brits

【2】Why did the author review many materials and interview many experts?

A. It was his work to do that.

B. He needed to prepare plenty of materials for his work.

C. He wanted to prove that his working style was correct.

D. He wanted to find out which way of working was better.

【3】What can we conclude from the passage?

A. We should make better use of technology.

B. Being busy makes us happier and more productive.

C. Small tasks can be done at home, but important ones must be done in the office.

D. In terms of working style, we should learn from the French.

【题目】 It’s well known that our human memory can fail us. People can be forgetful, and they can sometimes also “remember” things incorrectly, with damaging consequences in the classroom, courtroom, and other areas of life. Now, researchers show for the first time that bumblebees(大黄蜂) can be unreliable witnesses too.

Bumblebees are rather clever animals, which explains why Chittka has been studying learning and memory in the insects for the last 20 years.

Most times when people have studied memory in animals, errors in performance have been taken to mean that the animals failed to learn the task or perhaps learned it and then forgot. But what if animals can experience a more interesting type of memory failure?

To find out, Chittka first trained bumblebees to expect a reward when visiting a yellow artificial flower followed by one with black-and-white rings. During subsequent tests, bees were given a choice between three types of flowers. Two were the types they’d seen in the training before. The third had yellow-and-white rings, representing a mixed-up version of the other two. Minutes after the training, the bees showed a clear preference for the flower that recently rewarded them.

One or three days later, however, something very different happened when the bumblebees’ memory was put to the test. At first, the bees showed the same preference displayed in the earlier tests, but as the time went on, they began selecting the flower with yellow rings, even though they’d never actually seen that one in training before.

Chittka says that insects make similar errors in the conjunction (结合) of long-term memories as humans do. The ability to extract (提取) common features between different events in the environment might come at the expense of remembering every detail correctly. In bees, with their limited brain capacity (容量), the pressure to store main features of several objects rather than each individual object might be much greater, compared with humans.

【1】Which of the following might be the best title of the passage?

A. Human memory can fail sometimes.

B. Bumblebees make false memories too.

C. Humans are not as clever as bumblebees.

D. Bumblebees have extraordinary memory.

【2】Which of the following is the closest in meaning to the underlined word “subsequent”?

A. scientific B. accurate

C. following D. exceptional

【3】According to the passage, which of the following statements is NOT true?

A. Memory failure influences students’ study effects.

B. Bumblebees’ memory is complicated and worth studying.

C. The bees couldn’t make out which flower had rewarded them days later.

D. Bumblebees are stupid insects with limited brain capacity.

【4】 What does the test mentioned in Paragraph 4 tell us?

A. Short-term memories serve the bees well.

B. The yellow artificial flower appeals to the bees.

C. Bumblebees like the flowers with yellow-and-white rings.

D. Bees have remarkable abilities to distinguish colors.

【5】We can infer from the passage that ______.

A. Chittka thinks that bumblebees failed to remember the color of the flowers

B. Researchers have learned that bumblebees are unreliable animals

C. There exist no similarities between the memory errors in humans and bees.

D. It is less challenging for humans than bees to store main features of several objects.

【题目】There are 67 counties in the state of Alabama. Each county is rich with history and its own unique stories. Colbert County, located in the northwest corner of the state, has its share of exciting stories and claims to statewide fame. The county was created on February 6, 1867, and Tuscumbia became the county seat (the town in which the offices of the county government are located).

One of the most famous residents of Tuscumbia was Helen Keller. Helen Keller was born on June 27, 1880. Her home was a white frame cottage built by her grandparents. Since ivy (常春藤) grew everywhere, the house was called Ivy Green. It was here, at the water pump in the backyard, that Keller learned the word “w-a-t-e-r” with the help of her teacher, Anne Sullivan. Visitors to Ivy Green can walk under boxwood trees that are 150 years old. The home has furniture that the Keller family used. It also has Keller’s Braille (盲文) books and her original Braille typewriter.

Spring Park is Tuscumbia’s most popular park and favorite tourist attraction. This park has the world’s largest manufactured waterfall called Coldwater Falls. The Spring Park Light and Water Show is an amazing sight to see. It takes place every Friday, Saturday, and Sunday at sundown. The water appears to dance to music and colored lights. The music played during the show is recorded by singers and musicians from Alabama.

Fame Recording Studios is in the city of Muscle Shoals in Colbert County. The studio is the first successful recording studio in Alabama. It is best known for creating “Southern rock,” “Southern soul,” and “county soul.” Well-known performers like Aretha Franklin and musical groups such as Alabama and Lynyrd have made recordings at this studio.

Visitors can continue to explore music in Alabama by visiting the Alabama Music Hall of Fame in Tuscumbia. Built in 1990, this site recognizes the musical talents of more than 500 Alabama residents in a wide variety of musical styles, including country and rhythm and blues.

Truly, Colbert County has a lot of wonderful locations to visit. Guests will not be disappointed in a visit to this delightful place.

【题目】Italy is one country where beauty is prized more than any other virtue. That is, except in the small town of Piobbico, the self-declared World Capital of Ugly People. The road sign at the edge of the town even warns visitors that they are entering the ugly zone. People who consider themselves ugly have been gathering in Piobbico since the 1960s. That’s when Ugly Club president Telesforo Lacobelli established a dating agency for women who believed they were too ugly to attract husbands. Lacobelli believes that he is ugly himself because he has a short nose in a country where long or large noses have always been considered beautiful.

People from around the world travel to Piobbico to tell their sad stories of ugliness. During the annual Festival of the Ugly, which occurs on the first Sunday of every September, hundreds of people gather in Piobbico’s town square to elect the president of the Ugly Club. Lacobelli wins the election every year. The Ugly Club has over 20, 000 members. They carry ID cards that grade their ugliness from bearable to extreme. A prize is awarded to Ugly Club members who qualify as extremely ugly.

The Ugly Club president insists that ugliness is a virtue. Since beautiful people get a lot of attention for their beauty alone, they have to work hard to prove their other virtues. Ugly people, on the other hand, are genuine and do not have to prove anything to anybody, according to Lacobelli.

Lacobelli is a spokesperson for ugly people everywhere. He believes that the uglier one is, the better life can be. Though the club enjoys making fun of beauty, especially beauty contests, Lacobelli has a serious side as well. He believes that too many people suffer from financial and emotional pressures because they don’t meet society’s standards of beauty. The fact that beautiful people are more successful in the workforce is a problem that Lacobelli has attempted to bring forward to the Italian public and government.

D. Because he has won the members’ trust and admiration.

【3】Which of the following is true according to the passage?

A. Ugly people are most respected in Italy.

B. The Festival of the Ugly is held every two years.
