Dyslexia is a learning disorder, it interferes with the ability to recognize words, and for some readers to understand what they have read. Experts say dyslexia affects about five to ten percent of the population of the United States. Researchers have long known that people with dyslexia write or read words and lettersbackwards in the wrong order.
But a new study shows that people with dyslexia may have trouble redirecting their attention between senses, from seeing something to hearing something. The study suggests something that might help dyslexicpeople learn more quickly - play video games.
Vanessa Harrar of Britain’s University of Oxford led the study. She reported the findings in the journalCurrent Biology. The study suggests that dyslexic people may have trouble moving quickly from what they read to what they hear.
In the study, Doctor Harrar tested 17 people with dyslexia, and 19 others without reading problems. The volunteers were asked to push a button as quickly as possible when they heard a sound, saw a light or experienced both together. Doctor Harrar compared the speed of their reactions. She found that people with dyslexia were just as fast as the others when they saw only a picture or heard only a sound. But the Dyslexicshad a slower reaction time when they heard a sound and saw a picture at the same time, this may have an effect on how dyslexic children are taught how to read.
Doctor Harrar feels like playing video games could help dyslexic people shift from seeing to hearing more quickly. She adds that images in video games force the eyes to move and focus quickly. “Video game types of things pop out of here and there, they move your eyes around the screen quite quickly in response to things quite quickly, and the more you play a video game the faster you get that kind of thing. So, the video game is really training the attention system to move quickly,” said Harrar. When children learn the alphabet, they usually see the letter first and then hear the sound, or they see and hear the letter at the same time. The study shows that Dyslexics might learn more quickly if they hear the sound of a letter or word first before seeing it.According to Doctor Harrars study, the dyslexic people have difficulty in______.
| A．recognizing words |
| B．reading words backwards |
| C．writing letters in order |
| D．shifting from seeing to hearing |
Which factor affects the way dyslexic children are taught to read?

| B．They react as fast as others to a single picture or sound |
| C．It takes them longer to react to sounds and pictures together |
| D．It is difficult for them to understand before seeing the word |
How does the author suggest Dyslexics are taught based on the research finding?
| A．by putting hearing previous to seeing |
| B．by training the attention on games |
| C．by seeing first and then hearing later |
| D．by moving the eyes around the screen |
What can be the best title of the passage?
| A．Video Games Might Help Dyslexics |
| B．Dyslexia Affects Attention between Senses |
| C．Video Games Can Train the Attention System |
| D．Dyslexics Might Learn Better through Sound |
阅读下面的短文，从每题所给的四个选项(A、B、C、D)中，选出最佳选项。
A
A young girl and a man were recently found murdered in a parked car in a Boston suburb. The police found no sign in the car. Then they found a witness who had seen a car pass by the murdered couple's car. His description placed the car as a 1950 or 1951 Chevrolet.
Ordinarily, searching through the files for owners of elderly Chevrolets would have been an impossible difficult task because there were two and a half million such cars. In this case, however, the police had a powerful tool—the computer.
The Boston Registry of Motor Vehicles programmed its computer to screen all 1950 and 1951 Chevrolets within a fifteenmile radius(半径)of the suburb—the area in which the police believed the murderer was most likely to be found. Within minutes, the computer uncovered one thousand of wanted cars. A few hours of hand screening turned up a 1950 Chevrolet owner who lived close to the scene of the crime(犯罪)and who had received many traffic tickets. He was among the first suspects(嫌疑犯)to be investigated,_and signs connecting him with the murdered couple were found. He was arrested, and is now waiting for trial.It can be learned from the text that________.
| A．the murderer's car hit the couple's car but did not stop |
| B．the murderer was last found with the help of a Chevrolet owner |
| C．the police would not have found the suspect so soon but for the witness |
| D．searching through the files of Chevrolets owners was impossibly difficult |

| B．Chevrolet—A Type of an Old Car |
| C．Police—A Force in Catching the Murderer |
| D．Computer—A Help in Fighting against Crime |
Tourism Problems
Without proper planning, tourism can cause problems. For example, too many tourists can crowd public places that are also enjoyed by the inhabitants(居民)of a country. If tourists create too much traffic, the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country's economy(经济). It is important to think about the people of a destination(目的地)country and how tourism affects them. Tourism should help a country keep the customs and beauty that attract tourists. Tourism should also advance the wellbeing of local inhabitants.
Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country's economy can suffer.
On the other hand, if there is not enough tourism, people will lose jobs. Businesses will also lose money. It costs a great deal of money to build a large hotels, airports, air terminals, firstclass roads, and other support facilities(设施)needed by tourist attractions. For example, a major internationalclass tourism hotel needs as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel will lose money.
Building a hotel is just a beginning. There must be many support facilities as well, including roads to get to the hotel, electricity, sewers to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists, jobs and money are lost.Too much tourism can cause all these problems EXCEPT________.
| A．a bad effect on other industries |
| B．a change of tourists' customs |
| C．overcrowding of places of interest |
| D．pressure on traffic |
Not enough tourism can lead to________.
| A．an increase of unemployment |
| B．a decrease in tourist attractions |
| C．the higher cost of support facilities |
| D．a rise in price and a fall in pay |
The word“handle”in the last paragraph most probably means“________”．
| A．carry away |
| B．pick up |
| C．get in |
| D．take down |
(2010·全国卷Ⅱ)When you're lying on the white sands of the Mexican Riviera, the stresses(压力)of the world seem a million miles away. Hey, stop! This is no vacation—you have to finish something!

Excused from recycling(回收利用)because you live in a high rise with a rubbish chute(垃圾滑道)? You_won't_be_for_long. Miami's Mark Shantzis has made it simple for those living in tall buildings to use the chute and recycle too.
In Shantzis' HiRise Recycling System, a chute leads to pieshaped container with six boxes that can turn around when operated. The system, which fits in the same space as the chute and container now in use, enables glass, plastic, paper, metal and other rubbish to go into separate boxes.
The system is controlled from a board fixed next to the chute door. The board has a button for each class of recycling materials(as well as for un-recyclables). At the press of a button, a microcomputer locks all other floor's chute doors and sets the recycling container turning until the right box comes under the chute. The computer also counts the loads and gives a signal by phone when the box is full. And a particular piece of equipment breaks up the nonrecyclables.
Sorting(分类)recyclables before they are collected saves the use of expensive materials recovery equipment which otherwise has to do the sorting. Such equipment often makes recycled materials very expensive, so expensive that tons of recyclables remain wasted! Shantzis believes his system could help recycled materials become more costeffective.The purpose in writing this text is________.
| A．to encourage people to recycle their rubbish |
| B．to introduce a recycling system for high rises |
| C．to describe the use of computer technology in recycling |
| D．to explain the need for rubbish collection in high rises |

| D．break up the rubbish |
The biggest advantage of this new system is that________.
| A．it reduces the cost of recycling |
| B．it saves time and space |
| C．it saves money for people living in high rises |
| D．it makes better use of the existing recovery equipment |
B
(2010·安徽卷)American cities are similar to other cities around the world: In every country, cities reflect the values of the culture. American cities are changing, just as American society is changing.
After World War Ⅱ， the population of most large American cities decreased; however, the population in many Sun Belt cities increased. Los Angeles and Houston are cities where population shifts(转移)to and from the city reflect the changing values of American society. In the late 1940s and early 1950s, city residents(居民)became wealthier. They had more children so they needed more space. They moved out of their apartments in the city to buy their own homes. They bought houses in the suburbs(效区)．
Now things are changing. The children of the people who left the cities in the 1950s are now adults. Many, unlike their parents, want to live in the cities. They continue to move to Sun Belt cities and older ones of the Northeast and Midwest. Many young professionals are moving back into the city. They prefer the city to the suburbs because their jobs are there; or they just enjoy the excitement and possibilities that the city offers.
This population shift is bringing problems as well as benefits. Countless poor people must leave their apartments in the city because the owners want to sell the buildings or make apartments for sale instead of for rent. In the 1950s, many poor people did not have enough money to move to the suburbs; now many of these same people do not have enough money to stay in the cities.
Only a few years ago, people thought that the older American cities were dying. Some city residents now see a bright, new future. Others see only problems and conflicts. One thing is sure: many dying cities are alive again.What does the author think of cities all over the world?
| A．They are alive. |
| B．They are hopeless. |
| C．They are similar. |
| D．They are different. |
Why did American city residents want to live in the suburbs after World War Ⅱ？
| A．Because older American cities were dying. |
| B．Because they were richer and needed more space. |
| C．Because cities contained the worst parts of society. |
| D．Because they could hardly afford to live in the city. |
According to the 4th paragraph, a great many poor people in American cities________.
| A．are faced with housing problems |
| B．are forced to move to the suburbs |
| C．want to sell their buildings |
| D．need more money for daily expenses |
We can conclude from the text that________.
| A．American cities are changing for the worse |
| B．people have different views on American cities |
| C．many people are now moving from American cities |
| D．the population is decreasing in older American cities |
