1 . Most children now chat daily either online or through their mobile phones.     1     Some are shy in real life but are confident to communicate with others online; others find support from people of their own age on relationship issues, or problems at home.

Sometimes the online world, just like the real world, can cause problems, such as bullying (恃强凌弱) or arguments.     2     But there are also a few people who use the Internet for illegal aims. Children must be made aware of both the good things and the dangers.

    3     Just as you decide which TV programs are suitable, you need to do the same for the websites and the chat rooms your children visit. Remind your children that online friends are still strangers. Reminding them of the risks will keep them alert (警惕的).

    4     So it’s likely that your children may know more than you do. We get left behind when it comes to the latest gadgets and the interactive areas of websites, like chat rooms and message boards.     5     Chatters love to use abbreviations (缩略语) such as: atb (all the best), bbfn (bye bye for now), Idk (I don’t know), xlnt (excellent).

A．Going online is great fun.

B．Computer studies are part of schoolwork now.

C．The language of chat is strange to many parents, too.

D．There are some websites that are not suitable for the children.

E．To keep children safe, your management must cover the family computer.

F．They are connecting to a huge number of other children all over the world.

G．Surfing the Internet takes up too much of the time that should be spent on lessons.

2 . Food festivals are a common occurrence in the UK and take place in all sorts of places and at all sorts of times. Whatever your taste, there’s a food festival to match — no matter how specialized.

1. Meatopia

This three-day, London-based festival takes place at the end of August and is a meat lover’s paradise. In addition to a range of legally sourced meat products, from juicy burgers to tender steaks, attendees can listen to live music, watch butchery demonstrations, and attend informal meat-based workshops.

2. The National Honey Show

If you have a sweet tooth, then it could be that the National Honey Show, which started in 1921 and is the largest event of its kind, is the place for you to be. This three-day event attracts many local entries who showcase their sweet golden honey, some of which is sold globally.

3. The Orange Sauce Festival

Have you heard about a festival that is devoted only to orange sauce? Held in Cumbria, this sweet, fragrant festival has been running for 3 years. What attracts people most is a competition to find the best homemade orange sauce. There are thousands of participants from over 30 different countries across the globe, bringing their local snacks to share here.

4. The Ginger and Spice Festival

If you’d prefer something with a little more kick to it, then you could attend The Ginger (姜) and Spice Festival held in Market Drayton. Unlike other food festivals, it celebrates its town’s historic connection to Robert Clive, who returned from India with ginger. Because of this, they specialize in baking gingerbread, but also sell a range of traditional spices from mild to hot.

1. What do Meatopia and the National Honey Show have in common?

A．Both of them last for three days.	B．Both of them hold workshops.
C．Both of them originated from London.	D．Both of them have a long history.

2. If you are interested in foreign food, which festival do you like best?

A．The Meatopia.	B．The Ginger and Spice Festival.
C．The National Honey Show.	D．The Orange Sauce Festival.

3. What is special about the Ginger and Spice Festival ?

B．The ginger used in the festival is from India.

C．It sells spicy food.

D．The food is cooked by Robert Clive.

3 . Vehicles on our roads are now mostly petrol and diesel (柴油) cars, but their days cannot continue for much longer. A recent university study found that current electric cars could be used for 87 percent of daily car journeys in the US. That figure could rise to 98 percent by 2020.

One hurdle to the widespread adoption of electric cars has been “range anxiety” — drivers concerns about running out of electricity on a journey. While petrol stations are conveniently located across national road systems, the necessary network of electric charging stations is still being developed. That said, charging points are becoming increasingly common throughout the USA.

Attitudes towards electric vehicles have changed greatly over the last few years. Not that long ago, electric cars were met with distrust, and their high prices drove customers away. Thanks to improvements in battery capacity, recharging times, performance and price, the current generation of electric cars are starting to persuade picky consumers. Plug-in cars will soon give internal combustion engine (内燃机) models a run for their money.

As well as development on the road, electric vehicles are taking to the seas and skies. Electric boats are among the oldest methods of electric travel, having enjoyed several decades of popularity from the late 19th to the early 20th century before petrol-powered outboard motors took over. Now, the global drive for renewable energy sources is bringing electric boats back. Steps towards electric air travel are also being made, with Airbus and NASA among the organizations developing and testing battery-powered planes. The experiments could soon make commercial electric flight a reality.

Electric vehicles do not produce any emissions (排放). If the US could replace 87 percent of its cars with electric vehicles, it would reduce the national demand for petrol by 61 percent. However, because of the production processes and the generation of electricity required to charge these vehicles, they cannot claim (声称) to be completely emission-free. That said, as many countries continue to increase their use of renewable energy sources, electric vehicles will become even cleaner.

4 . It’s 3 o’clock and you’ve been hard at work. As you sit at your desk, a strong desire for chocolate overcomes you. You try to busy yourself to make it go away. But it doesn’t. Here is another situation. Perhaps you are not feeling well. The only thing you want to eat is a big bowl of chicken soup, like your mom used to make when you were sick as a child. Food cravings area strong desire for a specific type of food. And they are normal.

Scientists at the website How Stuff Works compare hunger and cravings this way. Hunger is a fairly simple connection between the stomach and the brain. They even call it simply “stomach hunger.” When our stomachs bur x up all of the food we have eaten, a hormone (荷尔蒙) sends a message to one part of the brain for more food, which regulates our most basic body functions such as thirst, hunger and sleep. The brain then produces a chemical to start the appetite and you eat. Hunger is a function of survival.

A craving is more complex. It activates (使活跃) brain areas related to emotion, memory and reward. These are the same areas of the brain activated during drug-craving studies. So, some scientists call food cravings “mind hunger.” People often crave foods that are high in fat and sugar. Foods that are high in fat or high in sugar produce chemicals in the brain. These chemicals give us feelings of pleasure.

In a 2017 study, researchers at Cambridge University found that “dieting or restricted eating generally increases the possibility of food craving”. So, the more you deny yourself a food that you want, the more you may crave it. However, fasting is a bit different. They found that eating no food at all for a short period of time lessened food cravings.

So, the next time you crave something very specific, know that your brain maybe more to blame than your stomach.

C．The findings of food craving.	D．What dieting may bring us.

5 . In recent years, China has witnessed the growth of luxury (奢侈品) brands. In this market, Chinese consumers are now the largest spenders. It’s clear that a new generation of young, materialistic people is increasingly relying on luxury brands to improve its self-image. I am a fashionist too, at least in spirit — I love to look at clothes and shoes. But I don’t understand why people spend lots of money on designer labels. When a young woman buys a handbag that costs two months of her salary, that’s a scary thing.

What’s interesting is that scientists have found that having luxury things doesn’t lead to happiness. Study after study has shown that although we want material things, when we get them we don’t suddenly become “happy” people. In fact, a series of studies by Leaf Van Boven at the University of Colorado, US, has shown that individuals who spend money on travel and similar experiences get more pleasure than those who invest it in material things. That’s because experiences are more easily combined with a person’s identity. If I travel to Yunnan, that adventure affects how I think in the future. My memories become a part of me.

Moreover, as Van Boven has observed, young people who pursue happiness through “things” are liked less by their peers. People prefer those who pursue happiness through experiences.

It’s natural to want to express yourself through your appearance. So my advice is: create a look that isn’t tied to a designer label. Convey your own message. Take some lessons from the late Apple co-founder Steve Jobs. He was always in Levis jeans and a black turtleneck. Mark Zuckerberg, founder of Facebook, routinely appears in hoodies and sneakers. These people, successful people, have style. You don’t have to break the bank to send a message about who you are. Take a trip. Go out into the world. Then come back and confidently create your own signature look.

1. What can we infer from the first paragraph?

A．The author enjoys buying luxury brands herself.

B．The author agrees to overspend money on material things.

C．The author is critical of youths tying their looks to designer labels.

D．The author finds it natural for fashionists to follow fashion trends.

2. Leaf Van Boven’s studies showed that ______.

A．people dislike those who love luxuries

B．traveling changes a person’s identity greatly

D．experiences can bring people more happiness than luxuries

3. What is the author’s advice on expressing oneself?

A．Be selective about designer labels.	B．Create your own personal unique style.
C．Choose simple and fashionable styles.	D．Try styles like Mark Zuckerberg’s.

4. The main purpose of the article is to ______.

A．prove how luxury leads to an unpleasant life

B．tell how to express yourself through appearances

C．report on a series of studies about luxuries and happiness

7 . At eleven, I decided to learn to swim. There was a pool at the YMCA offering exactly the opportunity. My mother continually warned against it, and kept fresh in my mind the details of each drowning in the river. But the YMCA pool was safe.

I had a childhood fear of water. This started when I was three years old and my father took me to the beach.The huge waves knocked me down and swept over me.

The pool was quiet. I was afraid of going in all alone, so I sat on one side of the pool to wait for others. Then came a big boy. He yelled, “Hi, how’d you like to be ducked?” With that he picked me up and threw me into the deep end.I landed in a sitting position, and swallowed water. But I was not frightened out of my wits—when my feet hit the bottom, I would make a big jump to come out of the surface. It seemed a long way down. I gathered all my strength when I landed and made what I thought was a great spring upwards. Then I opened my eyes and saw nothing but water. I tried to yell but no sound came out. I went down, down, endlessly.

When I came to consciousness, I found myself lying on the bed in the hospital.

I never went back to the pool. I avoided water whenever I could. This misadventure stayed with me as the years rolled by.It deprived(剥夺) me of the joy of boating and swimming. Finally, I decided to get an instructor. Piece by piece, he built a swimmer. Several months later, the instructor was finished, but I was not .Sometimes the terror would return. 

This went on until July. I swam across the Lake Went worth.Only once did the terror return. When I was in the middle of the lake, I put my face under and saw nothing but bottomless water. I laughed and said, “Well, Mr Terror, what do you think you can do to me?” I had conquered my fear of water.

9 . If you could travel in time, where would you go? Perhaps you would watch an original performance of a Shakespeare’s play in Elizabethan England? What about hanging out with Laozi in the Spring and Autumn Period? Or maybe you’d voyage far ahead of the present day to see what the future holds.

The possibility of time travel is indeed appealing. Stories exploring the subject have been around for hundreds of years. Perhaps the best known example is the science fiction novel The Time Machine, which was written by H. G. Wells and published in 1895 for the first time. It was adapted into at least two feature films of the same name, as well as two television versions, and a large number of comic book adaptations. It is generally credited with the popularization of the concept of time travel using a vehicle that allows an operator to travel purposefully and selectively. The term “time machine”, coined by Wells, is now universally used to refer to a vehicle transporting people into the far future.

But could time travel actually be possible? Some scientists say yes, in theory. They propose using cracks in time and space called “wormholes”, which could be used as shortcuts to other periods. Einstein’s theory of relativity allows time travel in extreme circumstances. And British physicist Stephen Hawking said you could travel into the future with a really fast spaceship—going at nearly the speed of light. Though building such a spaceship would of course be no simple task.

Even if you could travel into the past, there is something called the “grandfather paradox”. It asks what would happen if a time traveller were to go back in time and have his own grandfather killed for some reason, and therefore prevent himself from being born. If the time traveller wasn’t born, how would he travel back in time?

And would you really like to visit the future? In H. G. Wells’ book, the main character travels into distant time where he arrives at a beach and is attacked by giant crabs. He then voyages 30 million years into the future where the only living thing is a black object with tentacles (触角). If that’s what’s in store, maybe we are better just living in the present day after all.

2. Einstein’s and Hawking’s theories 　　　.

A．have similarities in many ways

B．push the invention of the first spaceship

C．have proved wrong by some time travellers

D．suggest the possibility to invent the time machine

3. In Paragraph 4, “grandfather paradox” probably refers to the idea that 　　　.

A．the traveller is prevented from meeting his grandfather

B．the traveller goes back in time to seek for his grandfather

C．the grandfather’s death makes the traveller’s birth impossible

D．The reunion of the traveller and his grandfather brings happiness

4. What is probably the author’s attitude towards time travel?

A．Unclear.	B．Skeptical.
C．Supportive.	D．Unconcerned.

10 . To help you understand what 5G is, and what it means to you, we’ve put together a handy guide here.

What is 5G?

    1    At its most basic level, 5G will be used to make calls, send texts, and to simply get online. But it’s going to be significantly faster than previous generations, and could open the door up to a range of exciting new uses.

    2    

5G will use new higher radio frequencies to send out data, which are less cluttered(挤了)and carry information much faster. While these higher bands(频段) are faster, they don’t carry information as far. That’s to say, smaller multiple input and output antennas (天线)will be used—promoting both signals and capacity(容量).    3    

Why is it better than 4G?

5G is expected to be faster than 4G, with some firms claiming it could be as much as 100 times quicker. The fastest 4G networks can deliver 传输)peak(峰值)download speeds of around 300 Mbit/s.    4    In real life, this could allow you to download a full HD film in less than 10 seconds!    5     It means there will be very little—if any—delay when you carry out tasks on a device(设备). While this will help improve things like gaming experiences, it could also pave(为…铺平道路)the way for safer self-driving cars—in which even a short delay could be life-saving.

Finally, 5G will have a larger capacity, meaning networks will be able to deal with several apps at once. Generally, this should mean that devices have a faster, more stable connection.

A．How does 5G work?

B．How will 5G affect you?

C．5G is also expected to have a lower lag(延迟).

D．5G is short for “5th generation mobile network.”

E．In comparison, 5G could offer download speeds of over 1 Gb/s.

F．Therefore, the similarity between 5G and 4G technology is huge.

G．This means 5G will support up to 1,000 more devices per meter than 4G.
