Dyslexia is a problem that restricts the ability to recognize words and connect sounds with letters when people read. People with this learning disorder may also have problems when they write. Dyslexia is not related to eyesight or intelligence. The problem involves areas of the brain that process language. Brain scientists are studying whether they can predict which young children may struggle with reading to provide them with early help. John Gabrieli at the Massachusetts Institute of Technology is leading the study of five-year-olds in about twenty schools in the Boston area.

They studied in the schools with kindergartens．And for all the children joining in the study, they give them a brief set of paper-and-pencil tests to look at which children appear to be at some risk for struggling to read. So far, fifty of them have been examined in a scanner, a special machine, to show brain activity. Written tests are not always able to identify dyslexia or other problems, while brain scans may offer a more scientific way to identify problems. And with reading problems, early identification is important. When it comes to helping children overcome reading difficulties, the younger the child, the more effective they are.

Reading problems are not usually identified until a child is in the third or fourth grade. The later children are recognized as poor readers，the less treatment can help. And, as Professor Gabrieli points out, poor reading can make education a struggle. Reading is everything. Even math and science have textbooks.

While the children are given tasks related to reading, the brain scans measure the extent to which certain parts of the brain become active while the children do the work. The scientists say they are pleased with early results from the study, but have a long way to go.

Dyslexia is a problem that interferes (干扰) with the ability to recognize words and connect sounds with letters when people read. People with this learning disorder may also have problems when they write. Dyslexia is not related to eyesight or intelligence. The problem involves (涉及)areas of the brain that process language.

Brain scientists are studying whether they can predict which young children may struggle with reading, in order to provide early help. John Gabrieli is leading a study of five-year-olds in about twenty schools. He says, “We partner with schools that have kindergartens. What we do is, for all the children whose parents permit them to participate, we give them a brief set of paper-and-pencil tests to look at which children appear to be at some risk for struggling to read.

So far, fifty of the kindergartners have been examined in a machine that shows brain activity. The scanner uses a high-energy magnetic (有磁性的) field and radio waves to “look” inside the body. Written tests which are often used in previous studies are not always able to identify dyslexia or other problems. Professor Gabrieli says, “Brain scans may offer a more scientific way to identify problems.

And with reading problems, early identification is important. Reading problems are not usually identified until a child is in the third or fourth grade. The later children are recognized as poor readers, the less these interventions can help. And, as Professor Gabrieli points out, poor reading can make education a struggle. Reading is everything. Even math and science require one to read textbooks.

1.What do we know about Dyslexia?

A.It results in poor eyesight.

B.It is related to brain activity.

C.It only causes reading difficulty.

D.It has an influence on intelligence.

2.What does the underlined word “interventions” in the last paragraph probably mean?

A.Approaches. B.Researches.

C.Instructions. D.Treatments.

3.How is Professor Gabrieli’s study different from early ones?

A.It is scientifically based.

B.It focuses on written tests.

C.It examines children’s brains.

D.It needs parents’ participation.

4.What can be a suitable title for the text?

A.Dyslexia – a Learning Disorder Involving Intelligence

B.Dyslexia – a Problem Relating to Kindergartners

C.A Way Identifying Dyslexia at an Early Stage

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 letters backwards 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 dyslexic people 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.

1.According to Doctor Harrar’s 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

2.Which factor affects the way dyslexic children are taught to read?

A. They react more slowly to a single picture or sound

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

3.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

4.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

Memory is the ability to keep track of things that have happened in the past. Memory really is learning. One needs memory to ride a bicycle. A dog needs to remember if it is to come when called.

Memory is said to be stored in the brain as a “memory trace（记忆痕）.” What makes up this trace is not known. Some scientists believe that certain chemical substances may carry certain memories. For example, one substance, when given to rats, causes them to fear the dark.

Other research into memory has to do with how the brain works. Psychologists use three means to find out how a person remembers. For example, give a person a grocery list. Let the person memorize the list, then put it away. The most natural way to find out how much a person remembers of the grocery list is to ask what he or she remembers. This is called the method of recall. Another method is called recognition. Give the person another grocery list. Ask him or her to choose items on the first list from the items that are on only the second list. Often a person will be able to recognize things that he or she cannot recall. A third method of finding how much a person remembers is called relearning. Here the person is asked to read over the first list. The person will probably learn the list the second time faster than he did the first time. The difference in the time it takes to relearn the list is thought of as a measure of how much a person has remembered.

One way of remembering something is to repeat it many times. Interest is very important. Boring lists of facts are much more difficult to remember than something that we understand and are interested in. Motivation, or wanting to do something, is also important. Motivation is linked with reward. For example, a hungry animal quickly learns how to do something if that action gets the animal food. In humans, wanting to learn is often motivation. The praise of a teacher or the knowledge that an answer is correct is rewarding.

1.We can learn from the 2nd paragraph that ___________       .

2.The way to pick out the items on the first list from the second is known as ________ .

3.What is considered as a measure of how much one has remembered?

4.A good way to train an animal to do something quickly is to ________.

Many scholars share the belief that interest is as _____ to learning as the ability to understand, even more so to some degree.

A. subtle   B. vital       C. similar   D. obvious

Pycnandra acuminate (喜树) is a rare tree native to New Caledonia that has the rare ability to collect heavy metals like nickel (镍) from the ground. The liquid circulated in its body is blue-green and reportedly contains up to 25% nickel.

In general, trees and heavy metals like nickel don’t really go well together. But Pycnandra acuminata make them live together. And that’s what makes Pycnandra acuminata so special. It sucks out normally poisonous levels of heavy metals from the soil and store them in its trunk, leaves and seeds.

The evolution of Pycnandra acuminate is believed to have occurred over millions of years, but scientists have yet to identify a universal principle of nickel intake and storage. The reason why such trees have formed the way of absorbing metals is also up for debate.

The most popular theory states that the concentration of nickel protects such trees from leaf-chewing insects. And studies have shown that nickel accumulated by these trees indeed harms many insects though some have developed a high tolerance to it. Another theory says nickel has effects of resisting bacteria, which protects the trees from various diseases. However, these theories are all just theories.

One thing that has been proven is the ability of Pycnandra acurninata to clean the soil with poisonous materials caused by human activity. There’s also clear potential for collecting heavy materials like nickel in these kinds of soils that will bring a few profits by conventional ways of mining. People can collect minerals contained in such soils from the blue-green trees。

Unfortunately, Pycnandra acuminata is is recently in a bad situation. Human activity in forests of New Caledonia has made Pycnandra acuminata in danger. Consequently, probably fewer than several hundred trees of this kind have remained as a result of the reduction of our forests.

1.What do we know about Pycnandra acuminata?

A.It has a blue-green color due to metals collected.

B.It is able to collect some heavy metals from the ground.

C.It sucks out a great deal of poisonous underground water.

D.It tends to grow in the soil with plenty of poisonous liquid.

2.What do the theories in paragraph 4 say about Pycnandra acuminata?

A.It indeed protects many insects.

B.It stores most nickel in its roots.

C.It protects itself through the concentration of nickel.

D.It makes its surrounding plants suffer from diseases.

3.What does the author mainly want to express in the last paragraph?

A.Pycnandra acuminata is in danger.

B.Forests are to blame for the reduction of trees.

C.Forests are decreasing as a result of human activity.

D.Pycnandra acuminata is under the protection of people.

4.In which section of a magazine is this next most likely to appear?

A.Bacteria and disease. B.Health and life.

C.Fashion and entertainment. D.Man and nature.

How to Level up Your Self-Control

By definition, self-control is the ability to do something that benefits your long-term goals, instead of something that might satisfy your immediate desires.1.--we end up sacrificing the well-being of our future selves all too easily.

2.?

Angela Duckworth, professor of psychology at the University of Pennsylvania, says allocating resources between your present self and future self is an ongoing struggle. For example, exhibiting self-control over spending time on video games and social media, two of the most common temptations（诱惑）of the current era, means battling against age-old mechanisms in your brain.

If you're willing to look deeply into your tendencies and weak points, you can recognize the handful of problems that you need to work on.

3.To improve self-control at work, Duckworth first recommends taking a future-oriented approach to your day, such as planning breaks and the time for checking emails in advance.

The problem of looking at your cell phone too often, say, can be solved by putting it on mute or, better yet, sticking it in your bag until lunch.4..

Finally, Duckworth advises laying a foundation of self-control that you can build of in the future.5.because of too little sleep the night before, or an insufficient meal in the morning. By practicing healthier living away from the workplace, you can gather the strength and stamina（毅力）to help you control your worst urges when it matters most.

A.One place to start would be the office

B.What problems do you need to work on

C.We've all experienced unproductive workdays

D.But for many of us, short-term satisfactions are irresistible

E.Why is exercising proper self-control so tricky for some, and how to do better

F.If you can resist resigning you may achieve more on your overall self-control

G.Removing the temptation from sight is key to ensuring you're faithful to your mission
