【题目】 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.

【题目】 If you’re anything like the average American, you probably check your smartphone more than50 times per day as a 2018 study found. 1 In fact, The University of Arizona found back in2012 that cell phones carry 10 times more bacteria than a toilet seat, largely because toilet seats are typically cleaned more frequently while personal electronics are largely overlooked.

As the novel corona virus (新型冠状病毒) continues to spread, the Centers for Disease Control and Prevention and the World Health Organization are advising the general public to wash hands often and disinfect (消毒) frequently touched objects and surfaces. 2

But cleaning your phone can be tricky, considering many of the standard cleaning products you’d typically use for disinfection could potentially damage your mobile device. You may want to wipe down your phones screen with some rubbing alcohol or a disinfectant wipe. 3 These phones have a coating on then to prevent oil or grease from your hand from sticking on the phone. Using alcohol or those types of everyday solutions directly on a phone, on its glass can harm it. 4

That lines up with the advice Apple and Samsung offer which warn not to use cleaning products. 5 If you need to disinfect your smartphone, consider looking into a UV light to kill the bacteria.

A.Avoid using alcohol.

B.But in doing so, you risk damaging your devices screen.

C.That means keeping your phone clean is important as well.

D.You should still be cautious when exposing them to liquids.

E.Instead use a micro fiber cloth and dampen it lightly with soap and water.

F.And each time you do, your mobile device picks up more bacteria from your hands.

G.Both companies say wiping your phone down with a soft cloth is the best way to clean it.

【题目】 Influenza is an infection caused by flu viruses travelling through the air and entering the body through the nose or mouth. From October 2018 to early May 2019, up to 61,200 people died due to flu complications, while up to 647,000 people were hospitalized, according to the Centers for Disease Control and Prevention. Despite similar symptoms, a cold is milder than the flu while flu symptoms develop more suddenly and severely and can impact your body above and below the neck. 1

Several factors can lead to Influenza. 2 You can catch the flu, breathing in these droplets, or touching objects such as doorknobs or keyboards that are contaminated with the virus and then touching your nose, or mouth. People under 4, or above 65 or with a weakened immune system are at greater risk of catching the flu.

Treatment without delay plays a dominant role. If you promptly see your doctor upon noticing symptoms, he or she may give you an antiviral drug, oseltamivir. 3“The best way to treat the flu is to rest, drink fluids and use any other remedies that best relieve your symptoms such as pain reliever for headaches and achy muscles.” says a professor of infectious diseases at Northwestern Memorial Hospital.

Prevention is better than defense.4 Experts widely agree that the single best way is to get the vaccine (疫苗) each year, which is appropriate for anyone 6 months and older. 5 Moreover, practicing good hygiene can prevent flu germs from spreading. Highly recommended are washing your hands, coughing or sneezing into a tissue, avoiding touching your nose and mouth, cleaning surfaces and objects like keyboards and telephones and avoiding crowded areas.

A.Approaches to flu vary from expert to expert.

B.You can escape catching influenza with some common-sense health practices.

C.When someone with the flu coughs or sneezes, droplets carrying the virus enter the air.

D.These can include fever, achy muscles, sore throat, cough, headache, chills, fatigue or vomiting.

E.The flu shot protects against the most common three or four flu viruses research indicates that year.

F.If taken within two days, the medicine can lessen symptoms and shorten the length of time you are sick by about a day.

G.To determine if you have the flu or a cold, your doctor will do a physical exam, ask about your symptoms, and possibly do a lab test.

【题目】 When Wilbur and Orville Wright finished their flight at Kitty Hawk, Americans celebrated the brotherly bond. The brothers had grown up playing together, they had been in the newspaper business together, and they had built an airplane together. They even said they "thought together." However, when the Wright brothers said they thought together, what they really meant is that they argued together. After long arguments we often found ourselves in the position of each having been pulled to the other's side,"

Orville reflected. I don't think they really got mad," their mechanic (机械师) remembered, but they sure got awfully hot."

The skill to get hot without getting mad is critical in life. But it’s one that few parents teach to their kids. We want to give kids a stable home, so we tор blng (兄弟姐妹) from quаrrеlng and we have our own arguments behind closed doors. Yet if kids never get exposed to disagreement, we’ll end up limiting their creativity. As the psychologist Robert Albert put it, the creative person-to-be comes from a family that is anything but harmonious, one with a “wobble (摇晃).”Orville Wright came from a wobbly family. The brothers often watched their father Milton Wright fight with school authorities who weren't fond of his decision to let his kids miss a half-day of school from time to time to learn on their own.

The Wright brothers weren't t alone. The Beatles fought over instruments and tunes. Steve Jobs and Steve Wozniak argued constantly while designing the first Apple computer. Brainstorming groups generate16 percent more ideas when the members are encouraged to criticize one another. The most creative ideas in Chinese technology companies come from teams that have real disagreement early on.

Children need to learn the value of thoughtful disagreement. We should teach kids that silence is bad manners. It disrespects the value of your own view point and your own voice. It's a sign of respect to care enough about someone's opinion that you’re willing to challenge it. Good arguments are wobbly: a team or family might rock back and forth but it never tips over. If kids don't learn to wobble, they never learn to walk; they end up standing still.

1What does the author say about the Wright brothers?

A.They always took advice from their mechanic.

B.They knew little about the newspaper business.

C.They often held conflicting opinions.

D.They kept a very tense relationship.

2What sort of father was Milton Wright?

A.Untraditional.B.Generous.

C.Scholarly.D.Sensitive.

3What does the author intend to do in Paragraph 3?

A.Summarize the previous paragraphs.B.Add some background information.

C.Introduce a new topic for discussion.D.Provide more examples to support his idea.

4What is the best title for the text?

A.Conversation matter in a family kidsB.Uncomfortable silence harms Kids.

C.Kids, would you please start fighting:D.Parents, would you please stop arguing?

【题目】 Have you ever made a mistake while trying to print from a computer? That paper probably went right into the recycling bin. From there, it is taken to a waste-handling plant to be eventually broken down and remade. But what if you could simply erase your mistake and reuse that paper? It may become available, thanks to a new technology.

It's a new type of rewritable paper that can be used more than 100 times. Words and pictures remain visible on it for at least half a year. This is nearly the first rewritable paper. But the marks on those earlier versions tended to fade away in less than three months.

Luzhuo Chen led the group that made the new rewritable paper. His team was inspired by pens that contain erasable ink. That ink disappears when heated. To make its new rewritable paper, Chen's group switched the ink from the pen to the paper. They covered one side of regular paper with the ink used in those erasable pens. Using a heated pen or printer, they can now write or print on this paper. That warmth makes the ink disappear.

This is the opposite of how writing usually works, where ink is applied to paper. With the new system, the spots where you write become white instead of colored because that heat makes the ink covering the white paper disappear.

Qiang Zhao has a creative mind behind another type of rewritable paper. He thinks Chen's paper is simple and doesn't cost much to make, so it should be easy and fairly inexpensive to produce. However, the paper will need a lot of ink. In large doses(剂量),chemicals in the ink can be bad for the environment and people's health. Zhao would like scientists to develop a safer ink. Still, he thinks this paper will have wide applications.

1Why does the author raise the questions in the first paragraph?

A.To prove the necessity of recycling paper.

B.To introduce the importance of rewritable paper.

C.To draw readers attention to the new technology.

D.To show the development of paper-making technology.

2What's the advantage of the new rewritable paper over earlier versions?

A.It can be reused for a lot more times.

B.The costs of producing it are much lower.

C.It can be produced in a much easier way.

D.The contents on it can be more long-lasting.

3Which of the following reflects Qiang Zhao's opinion on Chen's paper?

A.It still needs improving.B.It's somewhat impractical.

C.It does no harm to its users.D.It's worth promoting right away.

4What can we know about Luzhuo Chen's new paper from the text?

A.It shows colored words or pictures.

B.It doesn't require ink to write on it.

C.It will replace ordinary writing paper soon.

D.It has no requirement on the writing tool.
