1 . 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.

2 . Every festival has its own meaning. Labor Day, for example, celebrates the value of hard work. Thanksgiving is about showing thanks to people around you. And Valentines’ Day is a time when you express love to your loved ones. But somehow it now seems that all festivals we just care about one thing — shopping. And that can be a big problem.

“In a way, over-consumption (过度消费) is the mother of all our environmental problems,” Kalle Lasn once told CNN. Lasn is the organizer of Buy Nothing Day, a day set up in Canada in 1992 to fight against unhealthy spending habits, and has now become an international event. It’s held on the day, which is known as Black Friday — a famous shopping day in the US and Canada.

You can see the irony (讽刺) here.

Even though the idea of Buy Nothing Day was brought up 26 years ago, we seem to need it now more than ever. It’s just as Lasn said, all the different kinds of pollution in our lives today — bad air quality, the reduction of forest area, endangered animal species, and plastic bags found in the ocean — seem to be the same cause: over-consumption.

The latest example is the Singles’ Day shopping craze of Nov 11, which saw a new sales record. But as Nie Li, a campaigner at Greenpeace, told Reuters, “Record-setting over-consumption means record-setting waste.” And it was reported that last year the Singles’ Day packages left more than 160,000 tons of waste, including plastic and cardboard. The Collins Dictionary has also just named “single-use” its Word of the Year, pointing out the problem that there’re too many things we tow out after only using them once.

So, Buy Nothing Day might only be here for one day a year, but it’s not just to remind us to the a break from shopping on that day, but to change our lifestyle completely, focusing on fun “with people we care about” rather than wasting money on useless things.

3 . Some people love travelling while some prefer to stay at home. If you don’t love travelling, you can make a change now. Why?    1     Please read on to know more.

Travelling takes you out of your comfort zone. Your comfort zone is comforting.    2    When you step into new surroundings, you will learn about the world around you. Travelling alone is a great option. Some people might fear being on their own, but it can really help them grow.

    3    Are you afraid of water? If you are, go to the beach or a lake. Are you afraid of talking to strangers? If so, go to a new place and talk with people you have never seen. Remember, fear can be overcome.

Travelling is a good way to expand your mind. It gets you out of a routine and makes you use your brain, your ears and your eyes. While travelling, there are a lot of things that have to be taken in: new sights, new flavours, new noises, etc.    4    

Have you ever thought about travelling abroad as a volunteer? You can benefit a lot from this kind of trip.    5     Sometimes, you can even get all of your meals and accommodation for free.

4 .    

Cheating can happen in a lot of different ways.When people cheat,it’s not fair to other people，like the kids who studied for the test or who the true winners of a game were.

Many people like the action of cheating.In their opinion,it makes difficult things seem easy,like getting all the right answers on the test.But it doesn't solve the problem of not knowing the material and it won't help on the next test—unless the person cheats again.

Some people lose respect for cheaters and think less of them.The cheaters themselves may feel bad because they know they shouldn't get that good grade.And,if they get caught cheating,they will be in trouble at school，and maybe at home,too.

Some kids cheat because they're busy or lazy and they want to get good grades without spending the time studying.Other kids might feel like they can’t pass the test without cheating.Even when there seems to be a “good reason” for cheating,cheating isn’t a good idea.

If you were sick or upset about something the night before the day and couldn’t study,it would be better to talk with the teacher about this.And if you don’t have enough time to study for a test because of swim practice,you need to talk with your parents about how to balance swimming and school.A kid who thinks cheating is the only way to pass a test needs to talk with the teacher and his or her parents so they can find some solutions together.Talking about these problems and working them out will feel better than cheating.

1. What does the author think when kids cheat in class?

A．It is unfair to other people.

B．It does harm to their health.

5 . 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.

8 . It is quite reasonable to blame traffic jams, the cost of gas and the great speed of modern life, but manners on the road are becoming horrible. Everybody knows that the nicest men would become fierce tigers behind the wheel. It is all right to have a tiger in a cage, but to have one in the driver’s seat is another matter.

Road politeness is not only good manners, but a good sense. It takes the most cool-headed drivers great patience to give up the desire to beat back when forced to face rude driving. On the other hand, a little politeness goes a long way towards reducing the possibility of quarrelling and fighting. A friendly nod or a wave of thanks in answer to an act of politeness helps to create an atmosphere of good will and becomes so necessary in modern traffic conditions. But such behaviors of politeness are by no means enough. Many drivers nowadays don’t even seem able to recognize politeness when they see it.

However, misplaced politeness can also be dangerous. A typical example is the driver who waves to a child crossing the street at a wrong place into the path of oncoming cars that may not be able to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they want to.

An experienced driver, whose manners are faultless, told me it would help if drivers learnt to correctly join in traffic stream without causing total blockages that give rise to unpleasant feelings. Unfortunately, modern drivers can’t even learn to drive, let alone master the roadmanship (公路驾车技能). Years ago, experts warned us that the fast increase of the car ownership would demand more give-and-take from all road users. It is high time for all of us to take this message to heart.

1. Which of the following can be the best title for this passage?

A．Traffic Jams.	B．Good Manners.
C．Road Politeness.	D．Modem Drivers.

2. What often cause(s) troubles on the road?

A．Traffic jams.	B．The behaviour of the drivers.

3. According to the writer, what should a good driver do?

A．Encourage children to cross the road whenever they want to.

B．Beat back when forced to face rude driving.

C．Be able to recognise politeness when he sees it.

D．Join in a traffic stream quickly however other people feel.

4. It is not always right for drivers to _____.

A．master the roadmanship

B．neglect politeness when they see it

C．give a friendly nod in answer to an act of politeness

D．encourage old ladies to cross the road whenever and wherever they want to

9 . Donna Strickland was awarded the 2018 Nobel Prize in Physics jointly with Arthur Ashkin and Gérard Mourou.It’s the first time in 55 years that a woman has won this famous prize, but why has it taken so long? We look at five other pioneering female physicists — past and present — who actually deserve the prize.

Jocelyn Bell Burnell

Perhaps the most famous snub (冷落): the student Bell discovered the first radio pulsars in 1967, when she was a PhD student at Cambridge.The Nobel Prize that recognised this landmark discovery in 1974, however, went to her male supervisor, Antony Hewish.Recently awarded a £2.3 million Breakthrough Prize, which she gave away to help under-represented students, she joked to The Guardian, “I feel I’ve done very well out of not getting a Nobel Prize.”

Lene Hau

Hau is best-known for leading the research team at Harvard University in 1999 that managed to slow a beam of light, before managing to stop it completely in 2001.Often topping Nobel Prize prediction lists, could 2019 be Hau’s year.

Vera Rubin

Rubin discovered dark matter in the 1980s, opening up a new field of astronomy.She died in 2016, without recognition from the committee.

Chien-Shiung Wu

Wu’s “Wu experiment” helped disprove the “law of conservation of parity”.Her experimental work was helpful but never honoured, and instead, her male colleagues won the 1957 Nobel Prize for their theoretical work behind the study.

Lise Meitner

Meitner led groundbreaking work on the discovery of nuclear fission.However, the discovery was acknowledged by the 1944 Nobel Prize in Chemistry, which was won by her male co-lead, Otto Hahn.

1. When was the discovery of radio pulsars recognised by the Nobel?

A．In 1944．

B．In 1967．

C．In 1974．

D．In 1980．

2. Which woman is most likely to win a Nobel Prize later according to the text?

A．Donna Strickland.	B．Jocelyn Bell Burnell.
C．Lene Hau.	D．Vera Rubin.

3. What do we know about the five females?

A．The five female scientists did greatly in chemistry.

B．Vera Rubin had opened up a new field in geometry.

C．Lise Meitner’s teacher won a Nobel Prize for her work.

D．The five female scientists haven’t been awarded Nobel Prize.
