You try to keep your eyes wide open while watching a basketball match or a wonderful firework show in case you might miss something exciting in just the blink (眨眼睛) of an eye. But in fact, humans blink about 15 times per minute on average. Have you ever missed anything because you blinked? Probably not. Why is that?

According to a new study published in the journal Current Biology in September, our brain has the ability to skip the temporary darkness when we blink. It can keep visual information for a short period of time and then put it together to form an image without interruption.

In order to understand how this works, a group of scientists at the German Primate Center and the University Medical Center Gottingen in Germany conducted an experiment. In the study, the participants were asked to look at patterns on a screen whose direction could be shown in different ways, such as horizontally or vertically (垂直地). When one pattern was about to disappear and the next one was about to come, the participants had to indicate the direction that the next pattern would appear.

The researchers found that when the directions of two patterns didn’t match, the area in our brain which is responsible for visual memory was activated. This same area showed less activity when two patterns were in the same direction.

“The medial prefrontal cortex (前额叶皮层) adjusts current visual information with previously obtained information, and thus enables us to sense the world with more stability, even when we briefly close our eyes to blink，” Caspar Schwiedrzik explained in Science Daily. He is the first author of the study and also a scientist at the German Primate Center.

1.We don’t miss anything when blinking because our brain can ________.

A.remember all that we see B.deal with the missing image

C.imagine what our eyes miss D.recognize our pieces of memory

2.What does the underlined word “it” in Paragraph 2 refer to?

A.Visual information. B.Our brain.

C.Current Biology. D.The temporary darkness.

3.What do we know about the experiment?

A.The different directions activated visual memory.

B.Visual memory can be more activated by similarity.

C.Participants can interpret patterns differently.

D.The two patterns appear at the same time.

4.The passage is mainly talking about ________.

A.the brain’s structure B.the brain’s special skill

C.the brain’s activated patterns D.the brain’s directions

Blue light before bedtime can make it harder to sleep, and the screens on phones, computers and televisions give out plenty of blue light. This is all true. But if you consider blue light as a major problem affecting your sleep or your eye health, it’s time to change your mind.

Philip Yuhas, a professor of optometry (验光), writes at The Conversation, “Blue light isn’t a uniquely technological evil. It’s part of sunlight, and your eyes are exposed to plenty of it all the time. You’re fine.” The pigments (色素) and the lenses of our eyes actually block blue light fairly well—so in a sense, we already have built-in blue-blocking protection.

Adding more protection isn’t likely to help, though. You can buy glasses and screen filters (过滤器) that block blue light, but Yuhas points out they are probably a waste of money. He says, “The products that my patients ask about do not block out much blue light.” The leading blue-blocking anti-reflective coating, for example, blocks only about 15% of the blue light that screens give out.

You could get the same reduction just by holding your phone another inch from your face. Try it now and see if you notice a difference. No? Then it shouldn’t surprise you that a recent analysis concluded that blue-blocking glasses and coatings have no significant effect on sleep quality, comfort at the computer or retinal (视网膜的) health.

The American Academy of Ophthalmology doesn’t recommend blue-blocking products, either. Instead, if you’re concerned about your eye health or your ability to get into sleep on time, you already know what to do: Put the screens away at bedtime. Read a book or find something else to do. While you’re using screens, take a 20-second break every 20 minutes to look at something 20 feet away. If you get dry eyes when you look at screens for a long time, use artificial tears.

1.What do we know about blue light?

A.It produces kinds of pigments. B.It does serious harm to our health.

C.It can be blocked by our eyes effectively. D.It is a unique product of electronics.

2.What can be learned about blue-blocking glasses from the text?

A.They are widely popular B.They are almost useless.

C.They are inaccessible. D.They are reliable.

3.What does the author suggest readers do?

A.Try to wet dry eyes with tears. B.Keep a distance from blue light.

C.Stop using screens in the evening. D.Have regular breaks when using screens.

4.Which of the following would be the best title for the text?

A.Does blue light really affect your health? B.Are blue-blocking products recommended?

C.Where does blue light actually come from? D.How can we avoid the harm from blue light?

Tell a story and tell it well,and you may open wide the eyes of a child,open up lines of communication in a business,or even open people’s mind to another culture or race.

People in many places are digging up the old folk stories and the messages in them.For example,most American storytellers get their tales from a wide variety of sources,cultures,and times.They regard storytelling not only as a useful tool in child education,but also as a meaningful activity that helps adults understand themselves as well as those whose culture may be very different from their own.

“Most local stories are based on a larger theme,”American storyteller Opalanga Pugh says,“Cinderella(灰姑娘),or the central idea of a good child protected by her goodness,appears in various forms in almost every culture of the world.”

Working with students in schools,Pugh helps them understand their own cultures and the general messages of the stories.She works with prisoners too,helping them know who they are by telling stories that her listeners can write,direct,and act in their own lives.If they don’t like the story they are living,they can rewrite the story.Pugh also works to help open up lines of communication between managers and workers.“For every advance in business,”she says,“there is a greater need for communication.”Storytelling can have a great effect on either side of the manager-worker relationship,she says.

Pugh spent several years in Nigeria,where she learned how closely storytelling was linked to the everyday life of the people there.The benefits of storytelling are found everywhere,she says.

“I learned how people used stories to spread their culture,”she says.“What I do is to focus on the value of stories that people can translate into their own daily world of affairs.We are all storytellers.We all have a story to tell.We tell everybody’s story.”

1.What do we learn about American storytellers from Paragraph 2?

A.They share the same way of storytelling.

B.They prefer to tell stories from other cultures.

C.They learn their stories from the American natives.

D.They find storytelling useful for both children and adults.

4.What is the main idea of the text?

When you close your eyes and try to think of the shape of your own body, what you imagine (or rather, what you feel) is quite different from what you see when you open your eyes and look in the mirror. The image you feel is much vaguer（模糊的） than the one you see. And if you lie still, it is quite hard to imagine yourself as having any particular size or shape.

When you move, when you feel the weight of your arms and legs and the natural resistance of the objects around you, the “felt” image of yourself starts to become clearer. It is almost as if it were created by your own actions and the feelings they cause.

The image you create for yourself has rather strange proportions（部分）; certain parts feel much larger than they look. If you get a hole in one of your teeth, it feels enormous; you are often surprised by how small it looks when you inspect it in the mirror.

Although the “felt” image may not have the shape you see in the mirror, it is much more important. It is the image through which you recognize your physical existence in the world. In spite of its strange proportions, it is all one piece, and since it has a consistent(前后一致的) right and left and atop and bottom, it allows you to locate new feelings when they occur. It allows you to find your nose in the dark and point to a pain.

If the felt image is damaged for any reason—if it is cut in half or lost as it often is after certain strokes （中风）which wipe out recognition of one entire side –these tasks become almost impossible. What is more, it becomes hard to make sense of one’s own visual appearance. If one half of the “felt” image is wiped out or injured, the patient stops recognizing the affected part of his body. It is hard for him to find the location of feelings on that side, and, although he feels the doctor’s touch, he locates it as being on the undamaged side.

1.According to the passage the “felt” image________the mirror image.

A．is precisely the same as         B．is as clear as

C．often differens from             D．is always much smaller than

2.Which the following staterants is NOT true?

A．The felt Image is much more important because it helps you locate new feelings.

B．When you are in bed with your eyes closed, it is not easy to imagine your image.

C．When you move, the “felt” image of yourself starts to become clearer.

D．The “felt” image is not so important as the mirror image.

3.If a man loses the ability to recognize his right side,________.

A．he can’t locate the doctor’s touch on his left side

B．he can’t locate the doctor’s touch on his right side

C．he loses his sense of touch on the left side

D．he loses feeling on both sides

4.What is this passage mainly about?

A．Stroke victims’ “felt” images     B．Stroke victims’ mirror images.

C．The importance of “felt” images  D．The importance of mirror images.

Like to watch TV or play with your phone while you eat your dinner? Watch out—it could make you pile on the pounds. Not paying attention to our food makes us tend to more snacking later.

Over a series of experiments were carried out by researchers. For the first experiment, 39 normal-weight young women were randomly assigned to one of three experimental conditions: a high-distraction group, a low-distraction group, and a no-distraction group. Each person was given the same 400-calorie lunch consisting of several food items presented in a fixed order, and instructed to eat all of the items.

In the high-distraction group, the women were told to play a computer game while eating, and that they would win money if they did well. In the low-distraction group they were just told to play the game while eating; and in the third group they were just told to eat their lunch. Later in the afternoon, each participant had access to a variety of biscuits on a plate, and the amount each person ate was assessed by weighing the plate before and afterwards.

There was a significant difference between the groups. Those in the high-distraction condition ate 69 percent more snacks than the no-distraction group, and those in the low-distraction group ate 28 percent more than those in the no-distraction group .

A second experiment, involving a further 63 people, was similar but involved watching TV in the distraction condition and eating soup and bread. This found that those who watched TV while eating their lunch ate 19 percent more biscuits later on than those who had eaten their meal without any distractions.

A third experiment was also carried out, in which 45 normal-weight people were allocated to three groups. The first listened to an audio clip instructing them to imagine they were watching themselves eat—making them extremely focused on their own food intake. The second listened to a clip instructing them to imagine they were watching a celebrity—specifically David Beckham—eat , making them still focused on the food, but to a lesser degree;the third, which was the control group, just ate their lunch in silence. When all participants were given access to biscuits later, those in the self-imagining group-i.e. those who had really paid attention to what they were eating—ate far fewer than the other groups.

1.Why does eating dinner with a TV or a Smartphone make us fat?

A. Because we're more likely to snack later on.

B. Because we're paying more attention to our eating.

C. Because food is becoming more delicious while we're playing.

D. Because we need more calories while playing.

2.What is TRUE about the three experiments?

A. The low-distraction group ate the most snacks in the first experiment.

B. Non-distracted members ate more biscuits later in the second experiment.

C. Participants focusing on eating ate far fewer in the third experiment.

D. Each person was told to watch TV or play a game.

3.What would be the best title for the text?

A. Eating attentively doesn't help control appetite.

B. Attentive eating increases later snack intake.

C. Focusing on food increases later snack intake.

D. Distraction leads to more snacking later.

4.Where is the text most probably from?

A. A textbook.　　 B. A scientific paper.
