When you pull the headset over your eyes and ...

When you pull the headset over your eyes and the game begins， you are transported to a tiny room with white walls．Your task is to break out of the room， but you cannot use your hands， joystick or game pad．You must use your thoughts．

You turn toward a ball on the floor， and your brain sends a command to pick it up．With another thought，you send the ball crashing into a mirror， breaking the glass and revealing a few numbers scribbled on a wall．You mentally type those numbers into a large keypad by the door．And you are out．

Designed by Neurable，a small startup founded by Ramses Alcaide，an electrical engineer and neuroscientist （神经科学家），the game offers a way of selecting items in a virtual world with your thoughts．

Having a headset with virtual reality goggles （眼镜） and sensors （传感器） that can read your brain waves，it will be a few years before this device comes into the market． And it is limited in what it can do．But it works．I recently played the game，titled Awakening，when Alcaide and two Neurable employees passed through San Francisco， so did a few hundred others this month at the Siggraph computer graphics conference in Los Angeles．

Driven by recent investments from the US government， many startups and bigger companies are working on ways to mentally control machines， looking for smoother ways to use virtual reality technology．

"Neurotechnology has become cool，" said Ed Boyden， a professor at the MIT Media Lab who advises one of those startups．

At Neurable， Alcaide and his team are pushing the limits of EEG （脑电图） headsets． Although sensors can read electrical brain activity from outside the skull， it is very difficult to separate the signal from the noise． Using computer algorithms （算法） based on Alcaide's research， Neurable works to read activity with a speed and accuracy that's not usually possible．

The algorithms learn from your behavior．Before playing the game，you train them to recognize when you are focusing your attention on an object．A pulse of light bounces around the virtual room，and each time it hits a small colored ball in front of you，you think about the ball．At that moment，when you focus on the light and it stimulates your brain，the system reads the specific signals of your brain activity．

1.How can you break out of the room in the game？

A. Open the door with the joystick．

B. Type the numbers you have got into the keypad in mind．

C. Send a ball crashing into the door．

D. Use your hands to open the door．

2.What can be inferred from Paragraph 4 and Paragraph 5？

A. Many people in San Francisco have played this game except the author．

B. The US government didn't invest money in the virtual reality technology．

C. The device having a headset with virtual reality goggle has come into market．

D. A lot of startups and companies are doing research into mentally control machines．

3.Which is the best title of the passage？

A. A game you can control with your mind

B. The limits of EEG headsets

C. Sensors that read brain signals

D. Recent investments on virtual reality technology

“Keep your eyes on the ball.” That is good advice when you are on the playing field, and good advice for everyday life. “Keep your mind on what’s important,” is the way I’d put it. But people are funny. They think too much about the details.

I had a secretary once. She was very hardworking. I ran a school and people used to call up to enroll(登记) for courses. Berry used to get angry at the phone. “If they keep on ringing, I’ll never get my typing done!” she’d shout.

People just don’t see the big picture. One evening, after leaving work, I was sitting next to a man on the train. I was feeling tired. My eyes fell on the paper he had spread out in front of him. You know how you feel to read over someone’s shoulder?

I read the page and leaned back. I guessed I was waiting for him to turn it. After a while, I realized—he wasn’t turning the page. He just kept on reading.

Now if you knew the page he was reading, you’d know that there weren’t many words on the page to read anyway. The layout（版面） was mostly pictures. So I turned to the man and said,” You know, you really read very slowly.”

“What do you mean?” he asked. “Well,” I told him, “I read the page in about a minute, and you have taken about ten. And you are still reading. You know,” I went on “If you learned to read faster, you could get more reading done.” He remained silent for a minute or two. “If I read too fast, my paper wouldn’t last me to my station.”

1.The writer wasn’t satisfied with his secretary because ___.

A. she didn’t put first thing first

B. she was too busy

C. she was easy to get angry

D. she couldn’t finish her work on time

2.The man read newspaper in order to___.

A.　 take in information　　 B.　 enjoy pictures

C.　 save time　　　　　　 　　 D.　 kill time

3.The writer thinks that people seem to need a sense of ___.

A. what to read first　　 B. how to read fast

C. what is important　　 D. what is funny

If you’re wondering when you might get the flu, a new study indicates you should keep an eye on your local weather report.

According to a research published in the Journal of Clinical Virology, if you keep your eye on the weather and watch for the first major dip in the temperature, you can essentially mark your calendar in prediction for an outbreak the flu.

To figure out how the weather and flu outbreak may be connected, researchers analyzed statistics of 20,000 people in an area over three seasons. The number of people who caught the flu was then compared with local weather data.

After each season, the team noticed one consistent finding: The first really cold period with low outdoor temperatures and low humidity (湿度) was always followed by a week of a mass influenza outbreak.

The researchers say that aerosol particles (气溶胶粒子) containing virus and liquid are more able to spread in cold and dry weather. So, in theory, if you sneeze or cough and the surrounding air is very dry, the air will absorb the moisture and the particles containing the virus keep spreading through the air for a longer period of time.

Luckily there are ways to keep off the illness regardless of the weather. Washing your hands, coughing into the crook (弯曲) of your arm and getting vaccine (疫苗) are the best ways to prevent the flu from spreading. People over the age of 65, pregnant women and young children are at the highest risk of developing complications (并发症) related to the virus, according to the CDC.

1.From the first paragraph we can infer that 　　　　 .

A. people may easily fall sick

B. nobody can predict when one gets flu

C. flu is often related to weather changes

D. weather report plays an important part in life

2.How did the researchers draw the conclusion of the study?

A. By analyzing the data

B. By doing questionnaires

C. .By carrying out experiments

D. By making observation

3.Why do people catch the flu easily in cold and dry weather?

A. Cold and dry weather helps the spread of virus

B. The colder it is, the more kinds of flu there are

C. Gold and dry weather can prevent people from doing exercise

D. Low temperature can increase the number of aerosol particles

4.What can we learn about from the last paragraph?

A. The vaccines for flu

B. The main ways to cure flu

C. The most common kind of flu virus

D. The people who are easy to get flu

Did you ever notice that when you’re fat, men don’t look you in the eye? They look across your shoulder. There’s no eye contact.

My name is Leslie. I am a real person. Up until two years ago, I was never looked in the eye by anyone.

I was too tired to be a lover to my husband. I was falling asleep by 8 o’clock most evenings. When I did go out for an evening. my husband was ashamed of me. And he said so to my face. When I walked, my thighs scrape together. I couldn’t even cross my legs. I was fat. Not just “overweight”. Fat! I was 5’55” tall and weighed 205 pounds.

About 18 months ago, my husband Darrell left a “Dear Leslie” letter on my bed and asked for divorce.

I went to a psychologist for advice. I knew that my weight was the source of my troubles. But I’d tried 14 different diets, at which I failed one by one.

He listened carefully and recommended an entirely different program. This was not a “diet.” It was a unique new weight-loss program researched by a team of specialists who help to treat the severely fat. I entered the program. Within the first four days, I lost only three pounds. So I was disappointed. But during the three weeks that followed, my weight began to drop from 205 pounds to 124 pounds. To me it was a miracle.

The reason why the program worked was simple. I was always eating. I could eat six times every day. I could snack in the afternoon. Snack before dinner. I could even have snack at night while watching TV.

How can you eat so much and still lose weight?

The secret is in the combination of foods, approved by the research team, which you eat in each 24 hour period. You will enjoy a variety of meats, chicken, fish, vegetables, potatoes, sauces. Even some light wine or beer if you wish. But be sure to have them in the right proportion（比例）, thus a complete 24-hour fat-reduction cycle is formed.

Without hunger, without nervousness, it lets you lose pounds so easily. Once you lose the weight, you’ll keep it off. Forever, I am sure of that.

1.Leslie　　　　　　　　　 .

A. had never looked anybody in their eyes.

B. had difficulties in walking because she was too fat.

C. was disliked by her husband because she went to bed too early each evening.

D. was often embarrassed because she was overweight for her height.

2.Leslie went to psychologist for advice in order to 　　　　　　　　 .

A. lose her weight.　　　　　 B. recover her marriage

C. get a vegetarian diet　　 D. become an advisor

3.The weight-loss program worked very well. The reason is that　　 ___　　 .

A. Leslie ate very little food and sometimes even fast food.

B. Leslie only had snacks and never had dinners.

C. Leslie could have rich food several times a day in the right proportion.

D. Leslie had rich food whenever she felt hungry.

4.Where do you think this article is most likely to appear?

A. Daily newspaper.　　 B. Women’s magazine.

C. A part of a novel.　 D. Newsweek magazine.

Let’s be honest, kids are strange. And when you hear your three- year-old son arguing over who gets to be the mom while playing “house” alone in the other room, you might question if you’ve done something wrong as a parent. But don’t worry, it’s perfectly normal for your child to have an imaginary friend, and it even has some benefits. While your kids are benefiting from playing with their imaginary friend, try out these other ways to raise an intelligent child!

One of the biggest profits is that it promotes creativity. Just think about it-you have to be a special kind of creative to carry on a conversation with an imaginary figure that doesn’t respond. Developmental psychologist Marjorie Taylor told PureWow that your child’s creativity will remain with them as they get older, even when they stop hanging out with their “friend”.

Along with being more creative, they will also have a better developed and more different vocabulary as well as stronger social skills. Talking to “Sally” or “Bob” all day will allow them to practice their speech and conversation skills. Researchers at La Trobe University in Australia found that children who engage with their imaginary friends on a regular basis use more complex sentences and are more confident in everyday social situations.

There are also some benefits for the parents. If your child’s brothers or sisters aren’t around or they’re an only child, they have someone to entertain them while you spend the time on you never-ending to-do list. So even though it might get odd when your kids constantly ask you to set an extra plate at the table for their imaginary friends, they’ll benefit in the future from keeping them around. Having an extra member of the family can’t be that bad, the more the merrier, right?

1.Who is the three-year-old boy talking to while playing “house” alone?

A. His toy.　　 B. His mother.

C. His brothers and sisters　　 D. His imaginary friend.

2.How does Marjorie Taylor feel about children playing with heir “friend”?

A. It helps children develop better.

B. It relieves busy parents’ pressure.

C. It shows children’s loneliness.

D. It makes the family get closer.

3.What does the author suggest to parents?

A. Sparing time with children.

B. Taking children to play outside.

C. Adopting an extra member of family.

D. Letting children play with imaginary friends.

4.What is the best title for the text?

A. Ways to play creatively

B. Ways to raise an intelligent child

C. Benefits of children’s having imaginary friends

D. Benefits of letting your child play

高二英语阅读理解中等难度题查看答案及解析

You have two eyes and they are set close together on the front of your face. Have you wondered why? The reasons are simple and important to the way you see the rest of your world.

Your eyes are like two small cameras. A camera catches an image of an object and records it on film. Similarly, when you look at something, each eye takes in what it sees and sends this image to the back of the eyeball. Because your eyes are set close together, they view the world from about the same height but from slightly different angles. Working as a team, the eyes send the images to your brain, which puts them together into a single, centered image.

Seeing in stereo means seeing with two eyes working together, which is called stereoscopic sight. This allows you to view the world in three dimensions, or 3-D. Seeing depth helps you to judge the distance between you and the objects you see and to adjust to the changing angle at which you see something as you move closer to or farther away from it. If images are coming from only one eye, however, only two of these dimensions----height and width----can be perceived. A world seen with one eye is thus two-dimensional, as in a photograph.

Now consider why your two eyes are on the front of your face. Think of other animals with the same arrangement. They are all animals that hunt, like lions and wolves. Their eyes face directly in front of them. This provides a field of sight about 180 degrees wide, which is called binocular(双眼的) sight. On the other hand, animals that are hunted have eyes on the sides of the head, which provides nearly360-degree field of sight. In order to stay alive, they need to see things coming from the sides and from behind. However, without stereoscopic sight, they have difficulty determining how far a danger is.

With sight both stereoscopic and binocular, humans share with animal hunters the ability to see from side to side and to accurately determine the distance. If you think it would be great to have another type of sight, perhaps with hundreds of tiny eyes like many insects do, think again! Each tiny insect eye sees only a tiny part. Besides, what if you needed glasses? Be glad for the eyesight that you have.

1.According to the passage, the similarity of an eye and a camera is that they both　　　　　　　 .

A. can imagine objects　　　　　　 　 B. can record images

C. provide centered images　　　　 　 D. work at the same height

2.Stereoscopic sight is a result of having　　　　　　　　　 .　

A. two eyes close to each other that work together

B. hundreds of eyes, all seeing tiny parts of an image

C. a three-hundred-sixty-degree field of sight

D. one eye on either side of the head, each seeing a different image

3.What is the meaning of the underlined word “perceived” in Para3 most similar to?

A. known　　 　 B. seen　　 　 C. taken　　 　 D. understood

4.We can infer from the last paragraph that　　　　　　　　 .

A. our eyes work like cameras

B. animal hunters are glad for the sight they have

C. the three dimensions are depth, height and width

D. human beings are fortunate to have such eyesight
