第3题
A movie receives a high rating if there are only a few main characters whose voices a
re easy to recognize. Klein also likes an interesting story without too many changes in time and place.A large amount of dialogues between the characters is better than long silences or noisy action scenes.

Of course, visually impaired people can enjoy many films when a friend explains the parts that can only be seen.But that means that blind people cannot go to the movies independently. To solve these problems, some movie theaters have begun to offer recorded audio descriptions of the movements, scenery, and special effects that other audience members can see on the screen.Blind moviegoers receive a wireless headset to wear during the movie. This allows them to listen to the narration while still hearing a movie's music and other sounds that surround them in the theater.

Another blind movie reviewer, Jay Forry, writes movie reviews that are published on his website. He also writes for newspapers and is a guest on radio shows. Forry gives movies one of five ratings, including, "So good, blind people will like it" and "I'm glad I couldn't see it." Forry became a writer after going blind at the age of 20 and he decided to go to college. His first articles appeared in the college newspaper, and Forry's writing skills and sense of humor are what keep people reading his reviews or listening to them on the radio.After "watching" The Sixth Sense, Forry commented that he thought the movie was excellent, but that he envied the boy who was the main character: "He had six senses, and I only have four."

1、What is the best title for the passage? ______

A、Movies for the Visually Impaired People

A、receiving the lowest rating

B、filled with many characters

C、without too many dialogues

D、being not too complicated

4、What do theaters do concerning with visually impaired people? ______

A、They assign staff to explain some parts of the movie

B、They arrange movies especially for these people

C、They offer recorded audio description of the movie

D、They persuade these people not to go to the theater

Losing your ability to think and remember is prett...

Losing your ability to think and remember is prettyscary. We know the risk of dementia (痴呆症) increases with age. But if you have memory slips, you probably needn't worry. There are pretty clear differences between signs of dementia andage-related memory loss. After age 50, it's quite common to have trouble remembering the names of people, places andthings quickly, says Dr. Kirk Daffner of Brigham and Women's Hospital in Boston. The brain ages just like the rest of the body. Certain parts shrink, especially areas in the brainthat are important to learning, memory and planning. Changes in brain cells can affectcommunication between different regions of the brain. And blood flow can be reduced asblood vessels narrow. Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about. Butif you forget the plot of the movie or don't remember even seeing it, that's far moreconcerning, Daffner says. When you forget entire experiences, he says, that's "a red flag that something more seriousmay be involved." Forgetting how to operate a familiar object like a microwave oven, orforgetting how to drive to the house of a friend you've visited many times before can also besigns of something going wrong. But even then, Daffner says, people shouldn't panic. There are many things that can causeconfusion and memory loss, including health problems like temporary stoppage of breathingduring sleep, high blood pressure, or depression, as well as medications (药物) likeantidepressants. You don't have to figure this out on your own. Daffner suggests going to your doctor to checkon medications, health problems and other issues that could be affecting memory. And the bestdefense against memory loss is to try to prevent it by building up your brain's cognitive (认知的) reserve, Daffner says. "Read books, go to movies, take on new hobbies or activities that force one to think in novelways," he says. In other words, keep your brain busy and working. And also get physicallyactive, because exercise is a known brain booster.Why does the author say that one needn't be concerned about memory slips? 1..Why does the author say that one needn't be concerned about memory slips?()

A、Not all of them are symptoms of dementia.

B、They occur only among certain groups of people.

C、Not all of them are related to one's age.

D、They are quite common among fifty-year-olds.

第8题
In the United States, it is not customary to telephone someone very early in the morni
ng. If you telephone him early in the day, while he is shaving or having breakfast, the time of the call shows that the matter is very important and requires immediate attention. The same meaning is attached to telephone calls made after 11:00 pm. If someone receives a call during sleeping hours, he assumes it's a matter of life or death. The time chosen for the call communicates its importance. In social life, time plays a very important part. In the U.S.A. guests tend to feel they are not highly regarded if the invitation to a dinner party is extended only three or four days before the party date. But it is not true in all countries. In other areas of the are parts of the world. Thus, misunderstandings arise between people from different cultures that treat time differently. Promptness is valued highly in American life, for example. If people are not prompt, they may be regarded as impolite or not fully responsible. In the U.S. no one would think of keeping a business associate waiting for an hour, it would be too impolite. A person, who is 5 minutes late, will say a few words of explanation, though perhaps he will not complete the sentence.
