1 . American billionaire Elon Musk has demonstrated a technology designed to use a computer chip inside the head to control the brain. During a video demonstration on Friday, Musk provided details about the system, called Neuralink.
Musk says he hopes the technology can be used to treat neural disorders and help spinal injury victims regain body movement. Musk also believes the system could be used in the future to improve intelligence to help humans keep up with supercomputers and artificial intelligence (AI) technology.
During the show, Musk showed off a model of the Neuralink device. It is about 23 millimeters wide. It is designed to be implanted into a person's skull. Small wires would connect the device directly to the brain.
The Neuralink system is currently being tested in pigs, with plans to seek government approval for human testing sometime in the future.
A pig named Gertrude was also shown during the show. Musk explained that Gertrude had a Neuralink chip inside its head. The device is meant to record nerve activity in the pig's nose and mouth.
Musk said the company had three pigs, each with two chips. He described the animals as "healthy, happy and indistinguishable from a normal pig." Musk said the company was able to predict with "high accuracy" a pig's leg movement on a running machine using data from the chip.
Musk noted that Neuralink first wants to use the device on people with severe spinal cord injuries to help them talk and move using their brain waves. He said he is hopeful that, in the long term, those people could regain "full-body motion."
Some neuroscientists not linked to the company said the presentation suggested Neuralink had made great progress with the technology. However, they warned that many more studies will be needed to test the long-term success of such devices.

2 . Lizzy Brown, a 42-year-old mother of three from East Riding, Yorkshire, was diagnosed with cancer when she was 14 years old. Ms Brown received the diagnosis having woken up frightened on her 14th birthday. She was admitted to a hospital in Cambridge in 1989, where she was told that she shouldn’t expect to survive into adulthood.
While being monitored (监护) at the hospital, Ms Brown was looked after by a kind nurse called Debbie Bye. Ms Brown has never forgotten the good care that Ms Bye provided during her time of need. “My prognosis (预断) was very poor,”' Ms Brown said. “I wasn’t expected to live more than five years, but now I’m 42 with three children and there’s not a wheelchair in sight. She might have thought she was doing her job but it went above and beyond that. I remember watching Debbie work and being so inspired by the way that she did things. She showed me that children are children no matter what is wrong with them and she treated us all the same.”
The childhood cancer survivor always wondered what had happened to the nurse over the years,which is why she decided to put a call out on Twitter. Ms Brown tweeted an appeal to find Ms Bye, with her tweet being shared more than 1,000 times. Her action proved successful, as the two women were eventually able to make contact (取得联系) thanks to the power of social media.
“To be there when Lizzy was given her prognosis was something I will never forget,’’ said Ms Bye, who has since retired (退休) from hospital work and now works part-time in a school. “She was a teenager in denial and over the years I have often wondered what happened to her and came to the only conclusion I could and thought she had passed away. I am blown away.”

In order to protect skills
7 . You won't be able to control everything your teens do when they drive, but you can teach them about the importance of vehicle safety.
Locking the door upon entering the vehicle
Did your teens know they should lock the doors immediately upon entering the vehicle? If your teens haven t been taught this, then they probably won’t do so.
Driving a safe vehicle
Avoiding distractions
Looking at phones or controlling the radio while driving could make your teens seriously injured or worse.
You need to show that you’re confident of your teens’ driving skills,even if your teens’ speeding up too fast or hitting the brakes too hard scares you. Instead of yelling and stressing out on such occasions, try your best to speak calmly. They will react much better to quiet comments than cold words.
Respecting speed limits
There’s something about being young and learning to drive that comes with a strong wish for speed.
However, you can help them see the importance of following the rules and keeping themselves safe.
A.Staying calm |
B.Presenting the traffic rules |
C.So make sure they know that |
D.Teach them to lock their doors |

9 . At one point in June last year, Zeng Jiapeng was more than 10,000 yuan in debt to a smart phone app. The 23-year-old Shanghai citizen pays for his online purchases of food, clothes, and travel with Huabei, a virtual credit card that's part of Alibaba Group Holding Ltd.’s spreading stable of e-commerce. His spending often used to go beyond his only source of income: the 8,000-yuan monthly allowance from his parents. He tried to repay the debt in installments(分期), even borrowing from Jiebei, another Alibaba-owned credit service, but eventually his mother and father had to help him out.
Zeng’s story is typical of members of China’ Generation Z. These young consumers, born from the mid-1990s to the early 2000s, have little income and therefore actually no credit history. Yet they have easy access to credit from a variety of banks, financial-tech companies, and peer-to-peer (P2P) Lenders(网络借贷平台), plus other channels that are unregulated. The spending habits of the young in particular are causing concern. In some cases the younger generation is being tempted to overconsume via credit secured through technology. Unsecured consumer lending has expanded 20% a year in China since 2008. The amount of consumer finance available through the Internet will more than double, to 19 trillion yuan, by 2021, from 7.8 trillion yuan last year. Official data showed that almost 70% of China’s 50 million P2P borrowers were younger than 40.
As for Zeng, he’s trying to be a little more frugal, even though he is now trying to earn a little by himself. “I deliberately set the credit limit at a lower level,” he says, “so that hopefully I can better match my income with spending.”
Regulators(监管部门)last year launched a breakdown on peer-to-peer lending, which, besides being a source of easy credit, had also become a popular investment vehicle. The sector has shrunk to less than half its peak size as a result of forced shutdowns.
1. What can we learn about Zeng Jiapeng from the first paragraph?A.He was in debt because he bought smart phone app. |

10 . What do you usually do to comfort your friends when they are feeling sad or depressed? You probably pat them on the back or shoulder, or maybe you give them a big, warm hug.
We used to think that knowing when and how to comfort others was an ability that only humans have. But scientists have discovered that apes (猩猩)have this ability, too. Two researchers from Emory University in Atlanta, US, went to an Ape Protection Centre in Congo to study bonobos (倭黑猩猩),which are closely related to humans.
The researchers analyzed the bonobos' reactions after more than 370 cases of stressful situations, such as fights and losing temper, and found that some bonobos rushed to hug those that were screaming after being attacked, just like humans would have done.
However, researchers said that not all bonobos were able to comfort others. In the protection centre, many bonobos are orphans (孤儿)whose mothers were killed by hunters. They were found to be more anxious in times of tension and have greater difficulty controlling their own emotions, malting them worse at reaching out to help friends in need.
"Orphans, who have not had the benefit of a mother helping them handling their emotions, are much worse al comforting others,” Professor Frans de Waal, one of the researchers, told The Telegraph. "Bonobos with moms were able to curb their negative emotional reactions more quickly. Therefore, they pay more attention to others.” This pattern mirrors the way that human children have been found to react. Those who seem more capable of handling their own emotions—for example, the ones who can calm themselves down more quickly after upsetting experiences—are usually better at expressing their concerns for others .
1. Which of the following statements is TRUE according to the passage?A.Orphan bonobos never give a hand to friends. |
B.There were 370 bonobos involved in the research. |
C.Moms play a significant role in handling kids' emotions. |
