Ford is showing its first all-electric sports utility vehicle, or SUV—the Mustang Mach E, marking a major change in the U. S. car industry. Auto industry reporters got their first look at the new electric vehicle Sunday. The new Mustang can travel from 370 to 480 kilometers before needing an electrical charge(充电). Experts say the Mustang Mach E marks the start of an increase in electric vehicles offered by top U. S. carmakers.

There are 18 electric vehicle models for sale in the U. S. The research group IHS Mark it expects that number to grow to 80 by 2022. New vehicles will include pickup trucks and SUVs that are popular with American buyers.

Last year, electric vehicles made up only 1.5 percent of new vehicle sales worldwide. Auto Industry research company LMC Automotive predicts(预言) that will rise to 2.2 percent this year. In the U. S., electric vehicles were only 1.2 percent of sales in 2019. It is expected to be the same in 2020.

Automakers,however, see room for growth. They note that electric vehicles are getting 250 miles or more on a single charge. That means a buyer no longer needs to worry about running out of power during a day’s usual drive. Because of the added models and increased power, LMC predicts that they will make up 17 percent of worldwide sales and 7 percent of U. S. sales in 2030.

The first-generation of electric vehicles were simply existing models that were changed to electricity to meet government fuel economy rules. They did not sell well largely because they could not travel more than 100 miles between charges. But now, many can go farther than the average one-day driving distance. The five-passenger Mach E looks like a traditional Mustang. Engineers say the least costly model will be able to travel about 370 kilometers on one charge. The most costly model will be able to travel 483 kilometers.

1.What can be known from the first two paragraphs?

A.Americans like pickup trucks and SUVs best.

B.There will be more vehicle models to meet customers’needs.

C.Ford is the first company to make all-electric sports utility vehicles.

D.The long travel distance between charges is the car’s greatest advantage.

2.What do we know about the growth of electric vehicles in America in 2030 according to LMC?

A.It’s the fastest in the world. B.It is much below the world average.

C.It’s the same as the world average. D.It hasn’t changed very much.

3.How did the author develop the last paragraph?

A.By giving examples. B.By introducing new ideas.

C.By making comparisons. D.By following time order.

4.What can be a suitable title for the text?

A.Ford Starts New Electric Vehicles B.Electric Vehicles Are Better for Environment

C.Old Electric Vehicles Will Be Knocked Out D.Electric Vehicles Will Take Over the Market

The United States space agency will send a spacecraft to explore the sun more closely than ever before on Saturday. NASA'S Parker Solar Probe（探测器）will fly through the hot solar atmosphere and come within just 6 million kilometers of the sun's surface.

The Parker Probe will get almost seven times closer to the sun than earlier spacecraft. To do this, it will fly past Venus（金星）seven times over seven years. Each pass will change the probe's orbit by providing a gravity push. It will move ever closer to the sun and straight into the corona（日冕）, the sun's outermost atmosphere.

By exploring the sun's corona, scientists hope to learn why it is hundreds of times hotter than the sun's surface. They will also study what drives the solar wind.

The project was proposed in 1958, the same year NASA was established. Now, "it's becoming a reality," said project manager Andy Driesman.

The Parker spacecraft has a 2.4 meter heat shield（护罩）that is 11 centimeters thick. It is made of two carbon sheets. The front has a white coating to reflect sunlight. It is expected to shine red when it experiences the extreme solar heat. Almost everything on the spacecraft will be behind this shield to keep its scientific instruments relatively cool.

Besides, the spacecraft will also be traveling at a high speed. The probe will reach 690,000 kilometers per hour in the corona. The spacecraft will make its first flight past Venus in early October. Its first pass by the sun is expected in November.

The Parker Solar Probe is the first NASA spacecraft to be named after someone who is still alive. Eugene Parker is a 91-year-old professor at the University of Chicago. He predicted the existence of solar wind 60 years ago. He plans to be at Cape Canaveral Air Force Station in the southern state of Florida to see the launch.

1.What's the advantage of the Parker Probe compared to the earlier ones?

A.It can change the orbit by flying past the sun.

B.It can get closer to the sun and into the corona.

C.It can study the effect of solar wind.

D.It can fly through the hot solar atmosphere without protection.

2.What can be inferred from the passage?

A.Human had little achievements in exploring the sun.

B.Eugene Parker is the first one to study the sun.

C.The Parker Probe has to get close to the sun with the help of Venus.

D.Human can get close to the sun's surface within 6 million kilometers today.

3.What can we learn about Eugene Parker?

A.He started NASA.

B.He foresaw the solar wind when he was 31.

C.He designed the Parker spacecraft.

D.He will study the sun using the Parker spacecraft.

4.Judging from the content, the passage most probably belongs to 　　　　 .

A.a story book B.an advertisement

C.a science fiction D.a news report

Cars could be able to "talk" to each other to warn about dangers on the roads using 5G technology in future, according to researchers.

Researchers at Glasgow Caledonian University (GCU) believe 5G may enable driverless cars to send each other messages about dangers such as ice or deep holes.

And they believe the high-speed, low -delay (低延迟的) nature of 5G will improve driverless cars to the point where they will be safer than the cars being driven today. They predict the number of road traffic accidents which cause more than 1. 3 million deaths and up to 50 million people injured worldwide every year will drop greatly as a result.

Dr Dimitrios, a member of the research group, said, “To have a better idea of what the future will look like, think of having cars that not only use sensors (感应器) to find what's around them, but also can talk to each other about safety information nearby.”

“I'm sure anyone who has had a bad experience on frozen roads would have benefited from knowing about the dangerous conditions ahead of time so they could have changed their speed or, if possible, even avoided that route (路线) altogether.”

With the help of 5G, an early warning system in vehicles will come into use within the next few years. Cars that are close enough to the danger area will pass warning messages to other cars around them using communication technologies, but also to cars further away using 5G, fast and reliably. Then those cars will send the same information to cars near them and 80 on, forming a joined-up.

5G is an exciting mobile technology, which will give a great boost to smart cities and autonomous (全自动的) vehicles among many other things.

1.Which of the following will Dr Dimitrios agree?

A.Cars can talk with drivers using 5G.

B.5G will improve the safety of car driving.

C.Massages sent by 5G will never be delayed.

D.Over 1.3 million deaths are caused by driverless cars.

2.What will cars probably do with dangerous conditions with 5G EXCEPT____________.

A.changing their speed B.turning to another route

C.getting closer to the danger area D.sending warnings to nearby cars

3.What does the underlined word "boost" in the last paragraph mean?

A.Recovery. B.Push. C.Danger. D.Fame.

4.In which part of a newspaper is the passage probably found?

A.Science and Technology. B.Entertainment. C.Life. D.Transport.

Is traffic a big problem where you live? Increased cycling may be the answer. Where are the best places to live and cycle? A new report lists the best bike-friendly cities around the world.

Top of the list is Amsterdam, the bike capital of the world. An unbelievable 40% of all traffic movements are by bicycle. Copenhagen, the city of bikes, is a city where 32 % of workers cycle to work because it's fast and easy. Berlin is another European city that's great for cycling. The city has about 80 kilometers of bike lanes, and 50 kilometers of pavement (人行道)paths. Cycling accounts for 12% of total street traffic.

Barcelona has been praised for its cycle service ''Bicing''，a bicycle service that allows users to take and leave bicycles at any of the 100 stations spread around the city. The city has created a ''green ring'' that surrounds the city area of Barcelona with a bike path. There are 3,250 parking spaces for bikes at street level at present. Barcelona City is also building a new underground car park for bicycles.

The UK has its cycle-friendly cities too. Bristol is the birthplace of ''Sustrans'' — the cycle-route charity which was formed 30 years ago. One of their projects was turning an old rail line between Bristol and Bath into a bike route. Other bike-friendly cities in the UK include Cambridge and York.

Bicycle is a most popular means of transportation in China. Nowadays, riding a bicycle is also a good way to support low-carbon living. There are many riding routes in Beijing for outdoor-lovers to explore. Cyclists can get close enough to experience the history and culture of Beijing, including the Forbidden City, the Bird's Nest, Hutong etc.

1.Why do 32% of workers cycle to work in Copenhagen?(不多于六个单词)

2.What is "Sustrans'' ？(不多于三个单词)

3.What is also a good way to support low-carbon living nowadays?(不多于三个单词)

4.What is the passage mainly about?(不多于七个单词)

You wait 50 years for a flying car,and then three come along at once.First up is Vahana:an airbus project to develop batterypowered,single- seater aircraft,designed to follow predetermined routes,only changing directions to avoid accidents.Propellers(螺旋桨)on the wings will let it take off and land without a runway.

Second,Dubai recently announced plans to use self-controlled air taxis as a way to beat the terrible traffic jams.The Volocopter is an electric multi-copter with 18 propellers and a fully self-controlled system.It’s essentially a self-controlled aircraft with two seats and up to 30 minutes of flying time.

But,if you want something more like the flying cars of 1950s science fiction,try Urban Aeronautics’ Fancraft.The Israel-based company wants to realize the dream of”an aircraft that looks like the classic vision of a flying car:doesn’t have a wing,doesn’t have a propeller that can be seen,and can fly exactly from point to point,”says Janina Frankel-Yoeli,Urban Aeronautics’ vice president of marketing.Earlier flying cars needed runways to take off and land which was,as Frankel-Yoeli says,”not much better than owning a car and an aircraft.”To go from point to point requires vertical take-off and landing,but for many years that could only be done by helicopters or larger aircraft.Urban Aeronautics’ solution is to use light but powerful engines,lightweight materials,and a self-controlled system.Their fan design-propellers housed in some special tubes-is powerful but unstable,so the Fancraft would be challenging for a human to fly without any help.Instead,computer-aided control technology takes over the tiny,quick changes required to keep the car stable at speeds of 160km/h or more.

But don’t be glad too early yet.The main problem to a sky full of flying cars is rules.Not only will every aircraft need to pass strict safety tests,but a new system of air traffic control will be needed to deal with 3-D traffic jams above people who are not aware of what is happening in the sky.NASA is already working on that.Tests have shown that multiple unmanned(无人的) flying cars can communicate with each other to avoid accidents.In the meantime,flying cars will mainly be reserved for emergency services and a few VIPs.

1.Vahana is different from the Volocopter in that____

A.it is power-free

B.it is self controlled

C.its routes are fixed

D.its propellers can be seen

2.The underlined word”vertical”in the third paragraph most probably means____

A.going straight up or down

B.flying high and fast

C.going across back or forth

D.flying quietly and safely

3.What can we infer from the last paragraph?

A.NASA helps flying cars to communicate.

B.There will be no traffic jams if cars can fly.

C.Rules for flying cars have already been made.

D.It is unusual for ordinary people to use flying cars.
