1 . Slowly but surely, we’re moving closer and closer to 5G world. From smart-home security(安全) to self-driving cars, all the internet-connected devices in your life will be able to talk to each other at lightning-fast speeds. Objectively speaking, the fastest 4G download speeds in the US top out at an average of 10.42 Mbps. But by comparison, 5G promises gigabit(千兆) speeds.
“5G is one of those signs, along with artificial intelligence(人工智能)，of this coming data age,” said Steve Koenig, senior director of market research for the Consumer Technology Association. The self-driving vehicle(车辆) is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have a large number of data coming from the vehicle itself, and a variety of sensors(传感器) are collecting a lot of information to model its environment as it moves. It’s pulling in data from other vehicles about road conditions down the lane(车道). It could be weather information, but also connected infrastructure (基础设施)construction. There is lots of data behind that task, which is why we need high speeds.
Augmented reality glasses and virtual headset haven’t yet broken the mainstream, but tech companies are joyfully betting(打赌) that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable(显著的) because companies such as Apple are reportedly developing AR glasses to assist--or perhaps even replace--smartphones.
Ericsson stated at February' s Mobile World Congress how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components(部件), the glasses could rely on hardware for processing(处理)power.
But don't get too excited. There's still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction, so 5G isn’t concentrated(集中) only in big cities.

2 . It's not easy to grow up. Actually, it's far from easy. Growing up can be a real “pain” for some of us. We are always doing things that someone else makes us do and aren't allowed to do all the things we like. Sometimes we feel trapped, sometimes we are fearful, and sometimes we just don't understand why we can't stay young forever. When we look back on all the hardships in life with a positive attitude, we realize that all of our growing pains actually turn into growing gains!
Throughout our lives we are going to face many challenges and pains, but we should never let these obstacles keep us from following our dreams. We must overcome every obstacle one small step at a time.
As a young girl my parents forced me to do so many things that I never liked. They made me learn to play the violin and then the piano. At that time I hated music, just because it was what they wanted me to do. But looking back now, I am so glad that my parents encouraged me to take music lessons. Music has enriched my life in so many ways. I realize that my parents and teachers were always pushing me along, not because they wanted me to suffer but because they wanted me to succeed in life. They've always wanted me to have a better life than they did themselves.
Every moment of our lives we are either living or dying, so live life to its fullest! We are all going to experience growing pains, but they are just small pains in life. They might seem so huge at the time but we must be strong. Think about how we would feel if we had no fear and live life like that.
The future is ours! A little hard work and sweat never hurt anyone! If we realize that these pains are just small bumps（凸块）on our road to success we will realize that our growing pains are actually growing gains!

3 . One in five women and one in eight men are becoming more tired and less productive, according to a new Australian study on mobile phone use.
Led by the Queensland University of Technology in Australia, researchers surveyed 709 mobile phone users across the country aged 18 to 83 and asked them a series of questions based on a similar study 13 years ago. Identifying a phenomenon "technoference (科技干扰)", researchers discovered a significant increase in people blaming their devices for losing sleep, becoming less productive and even getting more aches and pains".
According to the study's lead author Dr Oscar, the issue is so bad that 24 percent of women and 15 percent of men are now considered to be " problematic mobile phone users". "When we talk about technoference, we're referring to the everyday intrusions (侵入)and interruptions that people experience due to mobile phones and their usage," he said. "Our survey found technoference had increased among men and women. For example, self-reports relating to the loss of sleep and productivity showed that these negative outcomes had significantly increased during the last 13 years. This finding suggests that mobile phones are potentially increasingly affecting aspects of daytime functioning due to lack of sleep. "
Compared to a 2005 study, "technoference" issues for 18 to 24-year-old experienced a surprising 40. 9 percent rise, while those aged 25 to 29 also recorded a dramatic increase of 23. 5 percent.
Oscar said that with the number of smartphone users around the world expected to surpass 2. 5 billion before the end of this year, the problem of "technoference" could get even worse. "The speed and depth of smartphone take-up makes our population particularly vulnerable to some of the negative consequences of high mobile phone use." he said. "Rapid technological innovations have led to dramatic changes in today's mobile phone technology, which can improve the quality of life for phone users but also result in some negative outcomes. "

4 . A year ago, I paid no attention to English idioms (习语), though my teacher emphasized (强调) the importance again and again. But soon, the importance of English idioms was shown in an amusing experience.
One day, I happened to meet an Englishman on the road, and soon we began to talk. As I was talking about how I was studying English, the foreigner seemed to be astonished. Gently shaking his head, shrugging his shoulders, he said, “You don’t say!” “You don’t say!” I was puzzled. I thought, perhaps this is not an appropriate topic (适当的话题). “Well, I’d better change the topic.” So I said to him. “Well, shall we talk about the Great Wall? By the way, have you ever been there?” “Certainly, everyone back home will laugh at me if I leave China without seeing it. It was magnificent.” He was deep in thought when I began to talk like a tourist guide. “The Great Wall is one of the wonders in the world. We are very proud of it.” Soon I was interrupted again by his words: “You don’t say!” I couldn’t help asking, “Why do you ask me not to talk about it?” “Well, I didn’t request you to do so,” he answered, greatly surprised. I said, “Didn’t you say ‘you don’t say’?” Hearing this, the Englishman laughed to tears. He began to explain, “You don’t say’ actually means ‘really!’ It is an expression of surprise. Perhaps you don’t pay attention to English idioms.” Only then did I know I had made a fool of myself.
Since then I have been more careful with idiomatic expressions. Remember: what the English teachers said is always right to us students.

5 . Roger was a thief, but he wasn’t very clever. When he was in school, he stole apples or oranges from other children. Sometimes he stole pencils or books from other children. But he always got caught.
The teacher spoke to Roger’s parents and they tried to stop him from stealing things, but Roger wouldn’t stop. He kept stealing.
When he was older, he began to steal from stores, but he was still stupid. Once, he went into a store wearing the clothes he had stolen the day before. They still had the price tags (标签) on them, and the store manager called the police. They warmed him that he would go to jail if he didn’t stop stealing.
Then Roger decided to rob a bank. He planned everything. He got some gloves so that he would not leave fingerprints, and a mask so that no one would recognize him.
“But what if they recognize my voice?” he thought.
He decided to write his message on a piece of paper so that he wouldn’t need to speak. He found an old envelope and wrote “give me all the money” on the back of it. He got a toy gun and went to the bank. He put on his mask and his gloves and showed the note to the bank clerk. The clerk gave him all the money, and Roger ran out of the bank and went home.
Ten minutes later he heard a knock on the door. It was the police. They had come to arrest him for robbing the bank.
“How did you find me so quickly?” asked Roger.
“It was easy,” said the police. “Your address was on the envelope!”

6 . A study of 27,000 men showed those skipping (不吃) breakfast were at a greater risk of heart problems. The British Heart Foundation said breakfast helped people resist (抵制) sugary snacks before lunch.
The men, aged 45-82, were studied for 16 years. During that time there were more than 1,500 heart attacks or cases of deadly heart failure. However, people who skipped breakfast were 27% more likely to have heart problems than those who started the day with a meal. The researchers took into consideration other lifestyle risk factors (因素) such as smoking and exercise.
Researcher Dr Leah Cahill told the BBC: “The take-home message is to eat in the morning when you wake up, preferably within an hour. The results show that something is better than nothing, but it’s always better to have something healthy and balanced.”
She said the timing of the meal seemed to be key and waiting until lunch rather than “having breakfast” may be straining (损伤) the body over time. This could be increasing the risk of high blood pressure and fatness which could in turn damage the heart. “Don’t skip breakfast,” Dr Cahill suggested.
Victoria Taylor, an expert with the British Heart Foundation, said: “These researchers only looked at men aged over 45, so we would need to see further research to prove that breakfast has the same effect on the heart health of other groups of people. What we do know is that a healthy breakfast can make that mid-morning biscuit less tempting, as well as giving you another opportunity to widen the variety of foods in your diet. Cereals (谷类食品) with low fat milk are a good way to start the day. Try a banana or dried fruit on top and you’ll be on your way to a fine day before you’ve even left the house.”
