On May 5，2017, China’s home-made passenger aircraft(飞机）C919 completed its 90-minute first flight and landed safely back at Pudong Airport in Shanghai.
C919 is developed by COMAC, a Chinese aircraft company. It is designed to compete with Boeing 737 and Airbus A320. The first C919 aircraft can carry 168 passengers and is able to fly a distance between 4,075 and 5, 555 kilometers. It’s reported that a C919 costs around 50 million dollars, less than half of a Boeing 737 or an Airbus A320. Up to now, more than 570 aircrafts have been ordered from 23 customers, mostly Chinese, but also American and Thai companies or airlines. COMAC aims to take one fifth of the world’s narrow-body aircraft market and one third of the Chinese market by 2035.
The name C919 has its special meanings. The letter C stands for both “COMAC” and “China”. The number 9 is pronounced as jiu in Chinese, which means “forever”. And the number 19 refers to its capacity(容量) of 190 passengers.
The large passenger aircraft is praised as “the flower of modern industry”. It is a symbol of the nation’s industrial and technological standards as well as the comprehensive(综合的) power. In order to realize the century dream of flying in the sky and the strategy(战略) of the nation, COMAC bears the nation’s dream and people’s trust. China considers it as a national pride.

This kind of robot looking like a helicopter(直升飞机) is a flying robot. It’s about 3 metres long, and it took about 4 years to develop the model. Its main functions (功能) are to collect information from the air, and send goods of up to 30 kilos to people trapped (被困住) by an earthquake. It has a high-definition 360-degree panoramic(全景的) camera. It can work day and night and is also able to send the latest pictures from the quake area.
Dr Qi Juntong, a researcher at Chinese Academy of Sciences, said, “The most important feature(特点) of this flying robot is that it doesn’t need a distant control. We just set the destination information on it, and then it takes off, and lands by itself. It flies as high as 3,000 metres, and as fast as 100 kilometres per hour.”
This robot has a different function—it can change as the environment changes. Its main job is to search for any signs of life in places where human rescuers are unable to go. As well as a detector(探测器) that finds victims and detects poisonous gases, a camera is placed in the 3-metre-long robot, which can work in the dark. Another use for the rescuers is the supply part, with its 10-metre-long pipe, people who are trapped in the ruins(废墟) will be able to get supplies including oxygen and liquids.
Experts have said that the robots will enter production and serve as part of the national earthquake rescue team as soon as possible.
1. According to Dr Qi Juntong, what makes this robot mainly different from the others?| A．It has more functions. | B．It is tall and has a special shape. |
| C．It has more advanced cameras. | D．It can work by itself once given the information. |

【推荐2】“Father of hybrid rice (杂交水稻)” Yuan Longping passed away at 13: 07 pm in Changsha of Hunan Province, Xinhua reported on Saturday.
Yuan Longping was born on the ninth day of the seventh month in 1930. He has helped China work a great wonder - feeding nearly one fifth of the world’s population with less than 9 percent of the world’s total land. In 1949, Yuan went to Southwest Agricultural (农业的) College and began his special connection with rice - a staple food (主食) of Chinese people. In 1970, Yuan discovered a special wild rice in the southern island of Hainan, then three years later he cultivated (培育) the world’s first hybrid rice. Now hybrid rice has since been grown across the country and farmers had a big harvest. Hybrid rice recorded an annual yield (年产量) about 20 percent higher than that of common rice - meaning it could feed an extra 70 million people.
Now the focus of Yuan’s hybrid rice project has changed from increasing output (产量) to green development. In September 2017, Yuan’s team developed a new kind of rice to deal with the heavy metal pollution.

【推荐3】When John was growing up, other kids felt sorry for him. His parents always had him weeding the garden, carrying out the garbage and delivering newspapers. But when John reached adulthood, he was better off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier. Far happier.
These are the findings of a 40-year study that followed the lives of 4,56 teenage boys from Boston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. " Boys who worked in the home or community gained competence(能力）and came to feel they were worthwhile members of society," said George Vaillant, the psychologist(心理学家）who made the discovery. "And because they felt good about themselves，others felt good about them.”
Vaillant’s study followed these males in great detail. Interviews were repeated at ages 25, 31and 47.Under Vaillant, the researchers compared the men’s mental－ health scores with their boyhood一activity scores. Points were awarded for part-time jobs, housework, effort in school, and ability to deal with problems.
The link between what the men had done as boys and how they turned out as adults was surprisingly sharp. Those who had done the most boyhood activities were twice as likely to have warm relations with a wide variety of people, five times as likely to be well paid and 16 times less likely to have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out.
Working--at any age-- is important. Childhood activities help a child develop responsibility, independence, confidence and competence-the underpinnings(基础） of emotional health. "They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this. Yet work isn’t everything. As Tolstoy once said, “One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one's work.”

【推荐3】Are you often in mind-wandering, enjoying the state of having nothing to do, or just standing and staring? Did you dream to get good grades and devote yourself to the tasks for a few days, however, your dream fell to zero as a TV play attracted you some day?
Do we need to have a dream? The founder of Wal -Mart, Sam Walton, says high expectation is the key to everything. The important thing in life is to have a great aim and the determination to achieve it, J. W. Goethe, the famous German poet and dramatist says. Successful people suggest that those who believe in the beauty of their dreams tend to have more self-motivation (自我激励)to keep on trying and enjoying the beauty of life.
Thomas Edison dreamed to light the world by the power of electricity. He tried over 2,000 different materials before he was able to create a market light bulb. It’s hard for many of us to imagine spending so much time and energy in exploring a possibility, which is most likely to come to a dead end but for Edison, who sticked to his dream, it was just an enjoyable process. As Edison says, The most certain way to succeed is always to try just one more time.
Helena, a 17-year-old girl, dreamed to build the magnificent sculpture (雕塑) in the world. She devoted herself to observing faces around her and making sculptures. She was woken up by her dream every morning rather than her alarm clock. She said she became passionate (有热情的) out of her dream, which kept her going through any difficulties and found pleasure in it.
You can benefit a lot from your dream, but do you know the behavior that is necessary to fulfill your dream? You have a dream and you truthfully want good grades. However, you can’t help playing on the smart phone and let go your homework. Or you rush through it so that you can get back to the smart phone. This is the case when the present-desire to play on your smart phone beats the will to reach the future goal, which is called immediate gratification. If you always behave like this, you may lose the chance to meet with your dream.
Your dream can inspire you. It can give you motivation to work hard. It helps you to focus on a path so that you are moving forward. Meanwhile, you need to set a long-term goal and work for it. The key to dream is concentrating on small wins, which gradually lead to genuine confidence. You will enjoy the whole process of rea lizing your dream as well as involving yourself into the pa ssion of the coming life.

【推荐1】"It's over! Thank goodness! "
School was over and I was tired. I sat at the front of the school bus. Janie, the driver, tries to break the uncomfortable atmosphere（气氛）by striking the match of talks. I try to listen politely, but usually I am too busy thinking about my day, On this day , however , her talk was worth（值得）listening to.
"My father's ill." she said to no one in particular（特别地）. I could see worry in her eyes. I had never seen her like this before. She always meets students with a smile.
With a sudden change of interest, I asked, "What's wrong with him?"
With her eyes wet and her voice unusual, she answered, "Heart trouble." Her eyes lowered as she continued. "I've already lost my mum, so I don't think I can stand losing him." I couldn't answer. My heart ached for her.
I sat on the seat thinking of the great pain（痛苦）my own mother was thrown into when her father died. I saw how hard it was, and still is, for her. I wouldn't want anyone to go through that.
Suddenly I realized（意识到）Janie wasn't only bus a driver, that was just her job. She had a whole world of family and cares too.
I suddenly felt very selfish. I paid no attention to Janie because she was a bus drive. I had judges by her job and brushed her off as unimportant.

【推荐2】A short while ago, I lost access to my WeChat account. I am not sure why it wouldn’t let me log in; perhaps it was my ancient, out-of-date phone. But I wasn’t too upset because it offered me an opportunity to take a break from social media—something more and more people are doing.
In the United States, Twitter is losing millions of users each month and Facebook has seen a 44 percent drop among its younger users. Some of these users may have deserted Twitter and Facebook for other social media platforms, while many others have quit because they felt that social media was having a negative effect on their happiness and overall quality of life.
Stars such as Taylor Swift and Ed Sheeren have taken a break from social media because they were tired of so many Internet trolls (网络喷子) leaving negative comments. Ordinary people (like me) are turning away from it because of the feeling that they were spending more time online and enjoying less.
It is not unusual for people to spend two or three hours a day posting or reading posts, to the point where it becomes an addiction. And it is an addiction. There is a chemical in your brain known as dopamine (多巴胺), which is sometimes called the “reward molecule” and its release gives you a feeling of pleasure. For instance, when you post a photo on WeChat and get a hundred likes, you feel happy. That’s dopamine at work.
In my case, being off WeChat left me with a feeling of anxiety (焦虑) for a few days. No doubt I missed my dopamine. And I got emails from friends wondering if I was fine or if I was just being anti-social (不喜欢社交的). But I soon began to feel quite peaceful and started to worry less about what other people were doing and concentrate more on my personal life. And it is an added bonus that I’m getting better sleep at night.
I’m not advocating (主张) that all of you quit social media, but spending less time on these platforms does bring you advantages. You could start by leaving your phone at home when you go to school (For some, that’s already a school regulation.) and it is also a good idea to charge your phone outside of your bedroom at night, as you are unlikely to get a good night’s sleep when the notification (通知) bell keeps ringing.
Someday I may reconnect with my WeChat account, but I’m not in a hurry. Life can be more relaxing and just as interesting without it.
