1 . Social media (社交媒体) is certainly an interesting place to learn others’ opinions. You can read everything from strange ideas to true facts and everything in between. But when you’re spending time online and reading so many opinions, it’s quite possible that you’ll sometimes see someone write something that you strongly disagree with.
In fact, you might feel so strongly that you feel like you should reply to this person at once. You might do some research, find some facts of your own and reply to what they’ve written. You finish writing out your reply, click (点击) “Post” (发布) and win the argument!
Except that it’s not really much of a victory. Most people don’t like it when other people disagree with their ideas, especially online strangers. It’s unlikely that they will change their opinion just because you argued with them. In fact, it’s possible that you made them feel more confident that they’re correct.
And the thing is, when you get in these kinds of fights online, it slowly influences you. You might not know it at first, but the argument that you take part in can actually have a bad effect on your mood. If you argue often, you start to enjoy arguing and then end up doing it even more. It’s a dangerous cycle (循环).
I guess the best thing to do is to tell yourself that most arguments aren’t worth it. There are much better and more interesting things to do, whether online or in real life.

2 . The Arctic is home to over 21, 000 kinds of animals and plants. Two thirds of it is the Arctic Ocean. From July to August, nearly 50 percent of the sea is ice and the sun sometimes shines in the sky during the summer. However, in November, the temperature drops sharply and the Ocean is completely covered with sea ice during the following 5 months. The Arctic winter is extremely cold. Actually, according to recent studies, the temperature in the Arctic is 18℃ higher than it was 125 years ago. The life of the local people is greatly influenced by climate（气候）change.

It’s very important for everyone to sleep. We spend about one-third of our lives sleeping. So we should pay more attention to the quality of sleeping. However, a lot of people have trouble in sleeping. Some people even take sleeping pills to help them sleep better. In fact, taking sleeping pills is very dangerous. That’ s because sleeping pills are habit-forming(上瘾的). If you take them for several weeks, you will find it hard for you to stop taking them. Then, what should you do if you have trouble getting a good night’s sleep?
Doctors say that the best thing to do is to get out of bad habits. In other words, you can’t stay up too late at night and you should get up earlier in the morning. However, you may still have trouble sleeping if you have problems or something else on your mind. Then it’s time for you to do some exercise to relax your tense muscles(紧绷的肌肉). If relaxing your body can’t help you, try to write down your worries on your mind. If you like listening to music, you can choose some music that is quiet and gentle. Be sure not to choose some music which is too loud, or you may get so excited that you can’t fall asleep.
Remember, choosing proper ways can help you sleep better.
1. Is it safe to take sleeping pills?2. How long do people sleep in their lives?
3. What can you do if relaxing your body can’t help you sleep better?
4. Do you think that getting up early is good for your sleep? Why or why not?

We are often told to pay attention to what our mothers tell us. Scientists have found that our brains greatly prefer the voices of our own mothers.
Scientists at Stanford University recently studied this. They scanned (扫描) children’s brains while they were listening to different sounds, including their mothers’ voices. They found that 97 percent of the time, children could recognize (识别) their mothers’ voices at once.
Hearing their mothers’ voices makes children’s brains more active. We usually just use one part of our brains to deal with sounds when we hear something. But when we hear our mothers’ voices, many parts of the brain start to work as well.
Why do we reply so strongly to our mothers’ voices? On one hand, when we are still in the womb (子宫) before we’re born, we hear our mothers talking. This makes us feel comfortable. On the other hand, mothers teach us talk and social skills by repeating words again and again. This way, when mother’s sound is heard again, more attention is paid to it.
Some sounds are necessary for our life and they bring us pleasure. But mothers’ voices are different and they make us feel comfortable. We will feel very relaxed when we hear our own mothers’ voices.

6 . Five years is a rather short time in the long history of China. But for digital (数字的) development, a lot of changes have taken place in many aspects of our life.
Nowadays, it’s normal for people to communicate on WeChat, the most popular mobile social media platform in China. People take less cash (现金) with them because most of the stores and hotels accept WeChat Pay and Alipay.
In China, holding a mobile phone means having the world in your hands. You can shop, travel, communicate, have fun by using a mobile phone, and all of these tasks can be completed with a few finger taps. Without mobile phones, life would seem dull.
By the end of 2016, there were 695 million mobile phone users in China, an increase of 12 percent on year-on-year basis. The average mobile Internet data traffic reached 172 megabytes per month, which was far more than the global average.
At the two sessions (两会), Premier Li Keqiang pointed out that in 2017 the speed of mobile network would be increased and the cost would be reduced greatly. Mobile rates for domestic roaming (国内漫游) and long distance calls would be cancelled (取消).
Meanwhile, the TD-LTE 4G communication technology developed mainly in China has been accepted and widely used across the world.
In 2020, China’s 5G network is in service. It helps China’s mobile telecommunication overtake (反超) the international community’s.

8 . These years, big changes to city life in China have attracted the world. Among them, four changes stand out. They are famous as “China’s four great modern inventions”
Online shopping
China has many big online shopping platforms, such as Taobao, T-mall, Suning and JD com. They have made online shopping a lifestyle choice for many people in China. Taobao even started“online shopping festival”, the Double Eleven. It’s reported that Taobao and T-mall may have more than 800 million goods. Their company Alibaba has developed into the world’s largest e-commerce(电子商务) company.
Bike sharing
Bike sharing is not a new idea, but China has given it a whole new meaning. It encourages people to ride the public-sharing bike over short distances, aiming to solve the “last mile”problem in big cities. We use mobile apps or cards to unlock bikes. We can leave the shared bikes at any bike station. This makes bike sharing much easier.
Cashless payment(无现金支付)
In China, now you don’t need cash or bank card to buy things. You could just pay with your mobile phone. You can scan(扫描) a store’s QR code(维码) to pay. Even a fruit seller on the roadside has a QR code for WeChat Pay or Alipay(支付宝) .
High-speed trains
On September 21, 2017, China’s new high-speed train Fuxing made its first run from Beijing to Shanghai. It ran at a speed of 350 km/h. This makes it the fastest train in the world. China has the world’s longest high-speed railway network. It’s more than 22,000 kilometers leading the game in these areas. And they are greatly changing people’s lives.
1. The world’s largest e-commerce company is ________.| A．T-mall | B．JD.com | C．Suning | D．Alibaba |
| A．cheap | B．difficult | C．convenient | D．boring |
| A．350km/h | B．220km/h | C．22.000km/h | D．320km/h |
| A．To use mobile apps or cards to unlock bikes. |
| B．To solve the “last mile” problem in big cities. |
| C．To leave the shared bikes at any bike station. |
| D．To ride the public-sharing bike. |
| A．China only has these four modern inventions. |
| B．Taobao started “online shopping festival”, the Double Eleven. |
| C．China’s high-speed trains are greatly changing people’s lives. |
| D．Even a fruit seller on the roadside has a QR code for Wechat Pay or Alipay. |
9 . From fire and the wheel to supercomputers and spacecraft—humans are natural inventors. The things we’ve invented have made our lives safer, smarter and easier.
Our inspirations for these inventions are often practical. We used fire to cook meat. The horse and buggy(马车) were used to move people and goods. But some of our most exciting inventions were inspired not out of necessity(必要性), but out of fantasy and imagination.
One of the best examples of this can be seen in From the Earth to the Moon, a novel written by famous writer Jules Verne. The novel, published in 1867, describes man traveling from our planet to the moon. Just over 100 years later, we would put a man on the moon for real.
But it is perhaps the worlds of film and television that inspire some of the most amazing future technologies. We can see technologies in many films and TV shows that are beyond our abilities to create—so far. But some of them have already come to life.
In fact, it is something like a two-way street—movie and TV show producers are inspired by the tech we already have and create fictional(虚构的) technology that is based upon it, while real-life inventors are inspired by the fantastic creations they see in films and on television.
These two different worlds share a common purpose—to allow us to express and realize our desire(渴望) to create. To give life to things we first see only in our imaginations. As we learn about some of these creations in the following pages, we’ll come to see how they have changed our lives and given us the freedom to unleash(释放) our creativity.
1. The second paragraph mainly talks about ________.| A．why inventions are practical |
| B．how inventions were inspired |
| C．what inventions were used for |
| D．where inventions are used |
| A．films and shows | B．our abilities |
| C．future technologies | D．inventors |
| A．Only inventors have the desire to create. |
| B．The horse and baggy were not inspired out of necessity. |
| C．The book From the Earth to the Moon came out after we sent men to the moon. |
| D．Real-life inventors often get inspirations from the fantastic creations in films and on TV. |
| A．In a novel | B．In a movie review |
| C．In a travel guide | D．In a science magazine |
10 . Many people often spend hours watching videos on their phones before sleep, with the lights off. However, do you know that using your phone in the dark is not a very good idea? The screen of your phone sends out blue light, which is quite harmful to your eyes. It can also be hard for you to go asleep.
What is blue light? Blue light is everywhere. It is sent out both by artificial（人造的）light and by our biggest light—the sun! Blue light is the part of visible（可见的）light which has the second shortest wavelength. Light with shorter wavelengths have greater power. The strong energy of blue light allows it to pass easily through the cornea（角膜）of our eyes. Therefore, blue light is quite harmful to our eyes.
However, blue light isn’t all that bad. After all, it is a part of sunlight. In fact, it can help to improve our sleep. The problem, however, lies in the bright screen lights we stare at each night. In other words, the problem isn’t exactly the exposure（暴露）to blue light, but the time of our exposure to it.
Some scientists studied the difference between reading a paper book and an e-book before bedtime. They found that it took longer for people who used an e-reader to fall asleep. These people were also less smart in the following morning.
So, to protect the quality of your sleep, avoid screens an hour or two before your bedtime. If you must use your phone before going to bed, keep a night lamp on.
1. Which of the following is harmful to your eyes according to the first paragraph?| A．Sleeping with the lights on. |
| B．Using the phones with the lights off in the dark. |
| C．Watching videos on your phones with the lights on. |
| A．The sun. | B．The eyes. | C．The paper books. |
| A．Because it is artificial light. |
| B．Because it is too weak to pass easily. |
| C．Because it can go through the eye cornea easily. |
| A．Blue light affects our lives. |
| B．Don’t use your phone or watch TV at night. |
| C．Don’t spend too much time on the bright screen. |
| A．Exposure to blue light can surely make you seriously sick. |
| B．Light with shorter wavelengths are usually more powerful. |
| C．Reading a paper book for too long may cause sleep problems. |
