21、The next time your brain refuses to recall a simple fact or name, be thankful. That could be a sign that your brain is getting rid of unnecessary information so that it can operate more efficiently, and help you make better decisions.
The researchers say there are numerous neurobiological(神经生物学的)studies conducted on how the brain stores information, a process called persistence (暂留). However, scientists also assumed that our occasional inability to recall facts was due to a are an the brain. In 2013, scientists discovered that as new neurons combine with the hippocampus(海马区)----a region of the brain that plays a significant role in learning and remembering---they overwrite old memories, making them harder to access. There is also evidence that the brain weakens or removes connections between neurons, in which memories are encoded.
The scientists have a theory on why the brain spends so much energy erasing memories. They say what the brain decides to forget is determined by our daily life. An example is that our brains remember phone numbers according to the need. Instead of storing this irrelevant information that our phones can store for us, our brains are freed up to store the memories that actually do matter for us. They also believe that memorizing too much detail could prevent us from making good decisions.
So the next time you are unable to recall a seemingly important fact, don’t be hard on yourself. Just throw it to your brain’s “rubbish can” to make room for information that can contribute to making you smarter! Remember, even Albert Einstein was absent-minded!
【1】What can we know from the first two paragraphs?
A. Persistence is not a process to store information
B. Once information is stored in the brain, it will last forever
C. Learning and memorizing take place in the hippocampus
D. New neurons will strengthen old memories
【2】The brain has to erase memories to __________.
A. recall important information
B. store more important information
C. store detail
D. remember phone numbers
【3】If some unimportant information is stored, it will be _________.
A. combined with the hippocampus
B. processed and memorized permanently
C. stored and decoded immediately
D. removed and forgotten soon
【4】What is the best title of the passage?
A. Scientists encourage us to forget things
B. The way our brains memorize and encode
C. Forgetting things may make you smarter
D. Why was Albert Einstein absent-minded?
22、 "Allez," caretaker Bernard Nsangu shouts in French as he gets ready to distribute a morning snack. Bonobos (倭黑猩猩) nearby tell their friends in the forest that pineapple is coming. Soon, more than a dozen bonobos have gathered near the grassy edge of their enclosure. With chimpanzees, the expectation of food can lead to aggression. But bonobos take a different approach, says Suzy Kwetuenda, a biologist at Lola. As you see, there is many negotiation," she says. "So that makes peace."
This sort of harmony is why, for more than a decade, scientists from around the world have been coming to this reserve just outside Kinshasa, along the banks of the Lukaya River. The researchers think bonobos may help explain how humans evolved the ability to be nice–at least some of the time.
Bonobos look like smallish chimpanzees, with whom they share 99.6% of their DNA. And both of these great apes share 98.7% of their DNA with humans, making them our closest living relatives.
What intrigues scientists is that bonobos and chimps often behave very differently, despite their genetic similarity. What's more, human behavior seems to include aspects of both species.
One way that bonobos differ from other great apes is in their eagerness to share, something that has been documented in experiments.
In one experiment, the scientists put two bonobos in next rooms. Then they gave one of the animals a plate of prized food, like bananas or apples, which have to be imported. The fruit plate was topped with a type of cream Kwetuenda calls "bonobo sauce." The bonobo with food was given a choice: eat alone, or use a special key to let in their neighbor.
"In our mind, we thought that because of nice food they would first eat," Kwetuenda says. "But we were surprised to see that roommate is more important than favorite food."
Later, the scientists repeated the experiment with three bonobos, one of whom was a stranger. This time, the bonobo with food usually shared with the stranger first, then invited the friend to join in.
【1】What does the author want to tell us by the example in Paragraph 1?
A.Food makes chimps aggressive.
B.Bonobos and chimps fight for food.
C.Bonobos and chimps get along well.
D.Bonobos are in harmony with each other.
【2】Why are scientists across the world interested in the reserve just outside Kinshasa?
A.To build a relationship between chimps and bonobos.
B.To have a better understanding of the life of bonobos.
C.To explore how human develop the capability to be kind.
D.To tell the difference between bonobos and human beings.
【3】What does the underlined word “intrigues” in paragraph 4 most probably mean?
A.Interests.
B.Annoys.
C.Threatens.
D.Thrills.
【4】What did scientists find from the two experiments?
A.Bonobos were put in different rooms.
B.Bonobos were willing to share with others.
C.Bonobos were expected to enjoy food together.
D.Bonobos treated friends better than strangers.
23、 Aristotle thought the face was a window onto a person’s mind. Cicero agreed. Two thousand years passed, and facial expressions are still commonly thought to be a universally valid way to judge other people’s feelings, irrespective of age, sex and culture. A raised eyebrow suggests confusion. A smile indicates happiness.
Or do they? An analysis of hundreds of research papers that examined the relationship between facial expressions and underlying ( 潜在的) emotions has uncovered a surprising conclusion: there is no good scientific evidence to suggest that there are such things as recognizable facial expressions for basic emotions which are universal across cultures. Just because a person is not smiling, the researchers found, does not mean that person is unhappy.
This may raise questions about the efforts of information-technology companies to develop artificial-intelligence algorithms (算法) which can recognize facial expressions and work out a person’s underlying emotional state. Microsoft, for example, claims its “Emotion API” is able to detect what people are feeling by examining video footage of them. Another of the study’s authors, however, expressed scepticism. Aleix Martinez, a computer engineer at Ohio State University, said that companies attempting to obtain emotions from images of faces have failed to understand the importance of context.
For a start, facial expression is but one of a number of non-verbal ways, such as body posture, that people use to communicate with each other. Machine recognition of emotion needs to take account of these as well. But context can reach further than that. Dr Martinez mentioned an experiment in which participants were shown a close-up picture of a man’s face, which was bright red with his mouth open in a scream. Based on this alone, most participants said the man was extremely angry. Then the whole picture was shown. It was a football player with his arms outstretched, celebrating a goal. His angry-looking face was, in fact, a show of pure joy.
Given that people cannot guess each other’s emotional states most of the time, Dr Martinez sees no reason computers would be able to. “There are companies right now claiming to be able to do that and apply this to places I find really scary and dangerous, for example, in hiring people,” he says. “Some companies require you to present a video resume, which is analyzed by a machine-learning system. And depending on your facial expressions, they hire you or not, which I find really shocking.”
【1】We can learn from the second paragraph that ______.
A.facial expressions are universal across cultures
B.it is hard to recognize some facial expressions
C.emotions and facial expressions may not be related
D.common facial expressions convey similar meanings
【2】In the passage, the word “scepticism” (paragraph 3) is closest in meaning to “______”.
A.great doubt B.similar interest
C.fierce anger D.strong support
【3】The experiment mentioned by Dr Martinez may prove that .
A.facial expression is an important way to communicate
B.machine recognition of emotion is not reliable at all
C.facial expression is not the only way to detect feelings
D.people may misread facial expressions for lack of context
【4】According to the text, which of the following statements is correct?
A.Facial expressions differ from person to person.
B.People with red face must be feeling extremely angry.
C.Artificial-intelligence algorithms can always work out a person’s inner emotional state.
D.Unbelievable to Dr Martinez is that job offers are decided by a machine-learning system.
【5】What does this passage mainly tell us?
A.Facial expressions are among the most universal forms of body language.
B.Computers can detect people’s mind by analyzing their facial expressions.
C.Facial expressions may not be the reliable reflection of a person’s emotions.
D.Companies can depend on machine recognition of emotion to hire people.
24、Researchers say a new electrical device placed in three paralyzed patients has helped them walk again. The lower bodies of the three patients were left paralyzed after they suffered spinal (脊柱的) cord injuries. But a device implanted in the spinal cord was able to send electrical signals to the muscles to permit them to stand, walk and exercise.
Scientists have discovered that neurons—which receive and send signals for muscle movements—often still work in injured patients with serious spinal cord injuries. However, past research into spinal cord injuries has centered on the stimulation of neurons. Now in the latest experiment led by Gregoire Courtine and Jocelyne Bloch of the Swiss Federal Institute of Technology in Lausanne, three paralyzed men were implanted a new electrical device designed to copy an action of the brain, in which it sends signals to the spinal cord that result in muscle movement. When the spinal cord receives the brain signals, it stimulates a collection of nerve cells that can activate different muscles.
The researchers reported that all three patients who got the spinal cord implants were able to take their first steps within an hour after receiving them. Over the next six months, the patients regained the ability to take part in more advanced walking activities, the study found. They were also able to ride bicycles and swim in community settings.
Unlike other attempts to help paralyzed patients walk by stimulating nerves through the back of the spine, Courtine said that his team redesigned the devices so signals would enter the spine from the sides. This method permits more direct targeting and activation of spinal cord areas, he said.
The team then developed artificial intelligence (AI) systems linked to the device. The AI controls electrodes on the device to send signals to stimulate individual nerves that control muscles needed for walking and other activities. However, because the patients muscles were weak from not being used, they needed help with supporting their weight, the researchers said. It also took some time for them to learn to work with the technology. Still,Bloch said, “The more they train, the more they start lifting their muscles, the more fluid it becomes.”
【1】What can be inferred from paragraph 2?
A.Neurons in paralyzed patients can’t work.
B.Paralyzed men recovered using a new device.
C.The new device can imitate the brain to send signals.
D.Stimulating the neurons is the focus of the latest research.
【2】How does the new device stimulate the spinal cord areas more directly?
A.By using the AI system.
B.By sending the signals to the brain.
C.By making signals enter the spine from the sides.
D.By stimulating nerves through the back of the spine.
【3】Which can best describe Bloch’s idea in the last paragraph?
A.Practice makes perfect.
B.It’s hard to please all.
C.Every garden has its weeds.
D.Put the cart before the horse.
【4】What is the purpose of this text?
A.To introduce the findings of a recent research.
B.To report the consequence of spinal cord injuries.
C.To recommend a treatment for paralyzed patients.
D.To compare a recent research with other previous researches.

26、阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
I must admit, I haven’t always liked animals. In fact, I distrusted them greatly while growing up, and I still fear the ones I don’t know personally. What set my beliefs in stone was being attacked—not once but many times, including the summer after second grade when I was bitten by a rabbit. Then, when I was nine and riding my dirt bike down the road, a large dog charged me and tried to bite my ankle. After all those negative experiences, there was one thing I knew for sure: All creatures, great and small, were no friends of mine.
After college in California, I returned to live the single life in Las Vega. Then I met Lisa. In no time at all, we fell in love, married and moved into a new house. Despite my avoidance of animals, Lisa had a dog called Bailey. Bailey didn’t like me, but he tolerated my existence once he realized I wasn’t going anywhere.
Things changed as spring came. We welcomed a new member of our family: our son Evan. One evening Evan grabbed hold of the dog’s tail. The irritated dog paused and turned to look at his stuck tail but waited patiently until being released. Still the stories I’d heard of animals attacking babies worries me.
Then my worst fear occurred. I sat on the couch (沙发) reading after a long day while my wife worked at the dining-room table paying the bills. I saw Evan crawl across the family-room carpet as he made his way behind the couch. One minute, all was quiet and then Bailey entered the room and headed to where Evan had crawled. I nearly jumped out of my skin when I heard the dog start a fearful barking behind me.
注意:
