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!

| A．make it easy for you to do something | B．make it difficult for you to do something |
| C．make you happy | D．make you full of energy |
| A．take music lessons | B．turn gains into pains |
| C．look back on hardships | D．live a successful life by suffering a lot |
| A．A little hard work and sweat are harmful to us. |
| B．We all have to experience growing pains. |
| C．Growing pains are necessary for us to grow up. |

3 . Usually, when you listen to music you will expect it to be enjoyable. Music is everywhere these days. It can make an experience much more pleasurable, unless we are watching a horror movie. Then, we expect something different, or something that is also horrible!
Mark Korven writes music for movies and TV. He provided the music for a successful horror movie called The Witch .Its director, Robert Eggers, asked Mark not to use any electronic music for this movie. He wanted to create a more real sound. Following this experience, Mark began to think about how a more natural sound could be made for future horror movies. He got in touch with his good friend, Tony Duggan-Smith, a musician and maker of musical instruments. Tony camp up with something great.
Tony created a special instrument that he calls The Apprehension Engine. It looks a little like a mechanic or engineer's workshop table. The handmade instrument was inspired by something called the Soundtrack Box, invented by the Oslo-based new- music technologist Koka Nikoladze. Every section of the instrument is there to create a sound or noise that can scare you.
Mark has said that his purpose when writing music for the The Apprehension Engine is to help produce sounds that are disturbing. He showed his skills recently by giving a hugely successful performance one dark evening in Brooklyn, New York on Friday 13", of course! In the shadow of candles, members of people jumped out of their skin.(吓得魂不附体)
So, is The Apprehension Engine a musical instrument, a machine, or an engine? If you believe that the purpose of music is to excite the listener, you can probably call it a musical instrument-it’s just that the sounds the instrument makes do not necessarily make you feel happy or relaxed.

| C．How to mix different music. | D．How to create music for horror movies. |
4 . Americans are drinking less milk today than they did 40 years ago. In fact, Americans are drinking about 40 percent less than they did in 1975. This decrease has led the United States dairy (乳品) industry to explore new ways to get people to drink milk. One method it is testing: helping to set up coffee bars in U.S. high schools.
Schools prepare coffee drinks in different ways, but milk is always the main ingredient in lattes (拿铁). That is why Midwest Dairy is providing financial help for a coffee bar at a fourth high school in the Fort Zumwalt, Missouri area during the upcoming school year. In exchange, the group will get data on how much milk is used for the lattes, as well as other information about food products with dairy.
Dairy groups have provided money to high schools in many states. At a high school in North Dakota, for example, a $5,000 grant from a dairy group helped pay for a coffee machine. The device makes lattes with about 0.23 liters of milk each. The drinks used around 2,000 liters of milk this past school year.
Not all high school coffee bars get money from dairy groups. Even then, the money may only cover a small amount of the costs. But school food operators say lattes give American teenagers another reason to stay on school grounds.
But not everyone thinks teens should drink coffee, or that they need milk. The American Academy of Pediatrics is against children consuming products with caffeine.
While dairy is a good way to get calcium and vitamin D, it is not the only way to get such nutrients, says Doctor Natalie Muth. She is a child care specialist and representative for the American Academy of Pediatrics. As for lattes, Muth said there are ways to persuade students to get the nutrients of milk without promoting caffeine use.
1. Why is the United States dairy industry willing to help set up coffee bars in American high schools?| A．To promote milk consumption. | B．To keep students healthy. |
| C．To test a new mixed drink. | D．To compare coffee with milk. |
| A．Loan. | B．Aid. |

5 . Australia and New Zealand’s health organizations have given their advice on when to use sunscreen (防晒霜), suggesting Australians apply it every day to avoid bad health effects.
A Sunscreen Summit took place in the Australian State of Queensland. During the summit, representatives from some of Australia’s leading research, medical and public health organizations examined the evidence on sunscreen use the determined that in most parts of the country it is beneficial to apply sunscreen every day.
“Up until now, public health organizations have recommended applying sunscreen ahead of planned outdoor activities but haven’t recommended applying it every day as part of a morning routine (惯例),” professor Rachel Neale from QIMR Berghofer Medical Research Institute said. “In recent years, it has become clear that the DNA damage causes skin cancer and melanoma (黑色素瘤), which is caused by repeated small exposure to sunlight over a period of time,” Neale said. “In Australia, we get a lot of sun exposure from everyday activities such as walking to the bus stop or train station,” Neale said.
A study showed that one in two Australians believed it was unhealthy and potentially dangerous to use sunscreen every day. However, Terry Slevin from the Public Health Association of Australia says it is wrong. “There is consistent and compelling evidence that sunscreens are safe,” Slevin said. “Importantly, medical trials have found that people who use sunscreen daily have the same levels of vitamin D as those who don’t,” Slevin added.
Australia has one of the highest rates of skin cancer in the world, which is made worse by the country’s close to Antarctica where there is a hole in the ozone layer (臭氧层), letting in higher numbers of UV rays.

6 . Tired of seeing so much garbage along the bank of River Schie in Rotterdam Dutch artist Tommy Kleyn decided to step up and do something about it. He alone organized a cleanup of the entire bank without leaving any garbage, proving that anyone can indeed make a difference if they want to.
Kleyn would cycle past a part of the Rotterdam riverway and see so much garbage along the bank. The situation troubled him, so he decided to spend 30 minutes every day cleaning the place up, filling one garbage bag a time. And when he posted pictures of his work on Facebook, a few of his friends volunteered to join as well. In five weeks, they had a 100 meter riverbank clean and completely rubbish-free.
Kleyn's action has received great support online, and he has managed to turn it into a small movement. He has set up a Facebook page through which he challenges people to spend 30 minutes a year to fill a garbage bag with rubbish. “It feels great and you'll make a big difference," he wrote. “People are free to share their 'before' and 'after' pictures on the page. The challenge has attracted people in countries・ The people came from as far as China to respond with their own photos and stories!"
“I want to show how easy it is to remove rubbish," he added. “Hopefully there will come a time when makers are thoughtful and their goods are no longer wrapped in layers of plastic."
Local officials praised Kleyn's work on the riverbank and helped him raise money for future projects as well. “People can sign up to help me one day a year. For this, they received a coupon, like going to a local restaurant at the lowest price. You can imagine what I've man- aged to do in 22 days, and what 22 men could do in a day. he said.

7 . There is a huge need for shark fins (鳍) in Asian countries. As a result, many sharks are caught and killed. According to reports, sharks are being killed at an shocking rate (速度) of up to 273 million worldwide every year.
Some experts predict that if the killing continues at the current rate, many shark species will be lost forever. It can be very dangerous. Sharks are very important and they should be protected.
In a study of the east coast of the United States, 11 species of sharks were eliminated from their range. Of the 14 species of ocean life that those sharks used to eat, the populations of 12 exploded and caused great damage to the ecosystem. For example, the cownose ray (鳐) population was no longer kept under control by sharks and so grew out of control. As a result, the rays destroyed the population of bay scallops (扇贝), their favorite food. The scallop fishery, which had been in good condition for over 100 years, was destroyed completely. Also, the removal of the scallops most likely had an effect on water quality as they were no longer there to perform their function (功能) of cleaning the water.
Sharks tend to eat very efficiently (高效地), going after the old, sick, or slower fish in a population, keeping that population healthy. Sharks help keep many populations of ocean life to the right size so that those prey (猎物) species don’ t do harm to the ecosystem by becoming too populated. The ocean ecosystem is made up of very complex (复杂地) food webs. For the most part, sharks are at the top of these webs and are considered by scientists to be “keystone” species, meaning that removing them may cause the whole structure to fall apart. Therefore, we should protect sharks because doing so is to protect the whole ecosystem.
1. According to the passage, in Asian, people kill sharks mainly because ________.| A．sharks are dangerous for people | B．there are too many sharks |
| C．shark fins are in great need | D．sharks often attack swimmers |
| A．Fed. | B．Removed. | C．Charged. | D．Protected. |
| A．water quality improved as well | B．bay scallops grew out of control |
| C．there are more food for shark | D．the local scallop fishery was harmed |
| A．They can’t find enough food to feed on. |
| B．They never eat the old, sick or slower fish. |
| C．Their large populations can harm the ecosystem. |
| D．They play a key role in keeping the ecosystem healthy. |
8 . My mother was diagnosed with Alzheimer’s (老年痴呆症) last summer. Suddenly, it was difficult for me to accept that the roles were now changed — my mother became my child, and I became her mother. I became impatient, argued with her, once I even yelled at her. Gradually, I was used to this kind of life. Now I am able to deal with her and the situation better. I have learned a lot of life lessons from the experience.
My mother reacts very sensitively to my feelings. That is typical of Alzheimer’s patients. When I visit her, feeling hectic and tense, she reacts immediately, takes on my mood, and becomes nervous and negative. But when I appear cheerful and attentive, she is happy. This has taught me to pay more attention to my own feelings when I am with other people.
Through the illness my mother has developed a childlike tactlessness (不得体). Eating out in restaurants, for example, is a bit embarrassing when she shouts at the waiter that the food is so bad or talks about people at the next table in a loud voice. Of course I make sure that my mother doesn’t hurt anyone, but I’ve stopped complaining about others and have become more tolerant.
I have also learned that everything has special value. When my mother got sick I didn’t want to burden my two daughters with it. They are young and have enough going on with their education, and starting their careers. I felt that it was simply my job as my mother’s daughter. The most wonderful discovery I’ve made through my mother’s disease may be that my children not only offer to help me, but that they take care of my mother on their own actively. They visit her often, play cards with her, and look at photo albums together with her. It shows me that it’s all worth it.
1. What does the underlined “hectic” in the Paragraph 2 mean?| A．delighted. | B．touched. |
| C．surprised. | D．stressed. |
| A．Being particular about clothes. | B．Being curious about feelings. |
| C．Being afraid of strange people. | D．Being sensitive to others’moods. |
| A．They are naughty. | B．They are considerate. |
| C．They are traditional. | D．They are selfish. |
| A．How I Cared for My Sick Mother. | B．How I Became More Tolerant. |
| C．What I Have Learned from Alzheimer’s. | D．Why I Am Feeling stressed. |
9 . 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. "
1. How are people affected by technoference according to the text?| A．It makes people addicted to communicating online. |
| B．It pushes people to work at a fast pace. |
| C．It causes people to sleep less at night. |
| D．It brings negative outcomes to people of all ages. |
| A．Young women. | B．Young man |
| C．Children. | D．Seniors. |
| A．Widely spread. | B．Easily hurt. |
| C．Deeply devoted | D．Absolutely accustomed. |
| A．The increasing side effects of smartphones. |
| B．Ways to solve technoference problem. |
| C．Smartphones and people's happiness. |
| D．The popularity of smartphones. |
10 . 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.
1. At first, when I heard “You don’t say”, I thought the foreigner meant __________.| A．he was only interested in the Great Wall | B．I had talked too much |
| C．he was not interested in the topic | D．I had to stop talking |
