Flying has shrunk the world! It’s now possible to travel around the globe quickly and easily. Jumping on a plane and jetting off on holiday or a business trip is the norm for many of us, and with the rise of budget airlines, the number of people taking to the skies is increasing. But while air travel is costing us less, the cost to the environment is going up.

Climate change is something we’re all aware of now, and aviation companies know that some of the blame for this is being pointed at them. Last year airlines were forecasted to use about 97bn gallons of jet fuel.

But while we could think twice about taking a flight in the first place, particularly a short trip that could be made by train, technology might be the answer to reducing emissions and minimising the environmental damage.

Recent developments have focused on reducing the amount of fuel airliners(大型客机) burn. Making flying green and sustainable was the hot topic at the recent Dubai Air Show. There was talk of advances in engine technology, making them more efficient, and possibly using biofuel to power aircraft.

Rios Galvan, a bioenergy expert and professor at Khalifa University in Abu Dhabi, told the BBC that “these have the capacity to reduce the carbon footprint anywhere between 50-80 percent when you compare them to fuels.”

And Phil Curnock, chief engineer of the civil future programme at Rolls-Royce, also suggested that electric hybrid engines (混合动力发动机) could play a part for smaller aircraft, covering shorter distances. He says “it offers the possibility of a carbon-neutral flight for a limited range.”

Of course, aircraft manufacturers are constantly looking at ways to make their planes more fuel efficient. Boeing’s Dreamliner, for example, is already in operation and uses 25 percent less fuel per passenger compared with aircraft of a similar size. Other improvements include better aircraft aerodynamics (空气动力学), changes to ways aircraft taxi (滑行) on runways, and the use of lighter materials.

1.What can we infer from Paragraph 1?

A.The earth gets smaller.

B.Budget airlines become popular.

C.Flying is favorite among passengers.

D.Air travel can do harm to environment.

2.What does the underlined word “minimising” mean?

A.Lowering. B.Consolidating.

C.Weakening. D.Increasing

3.Which of the following is true, according to the passage?

A.Boeing’s Dreamliner is a green aircraft.

B.Biofuel is a necessity to power airliners.

C.Electric hybrid engines have their limitations.

D.Ways will be found to reduce fuel consumption.

4.How can aircrafts be made more fuel efficient?

A.By bettering runways. B.By making smaller aircrafts.

C.By using the lighter materials. D.By using aircraft aerodynamics.

New technology links the world as never before. Our planet has shrunk. It’s now a “global village” where countries are only seconds away by fax or phone or satellite link. And, of course, our ability to benefit from this high-tech communications equipment is greatly increased by foreign language skills.

Deeply involved with this new technology is a kind of modern businesspeople who have a growing respect for the economic value of doing business abroad. In modern markets, success overseas often helps support domestic business efforts.

Overseas assignments are becoming increasingly important to advancement within executive ranks. The executive stationed in another country no longer need fear being “out of sight and out of mind.” He or she can be sure that the overseas effort is central to the company’s plan for success, and that promotions often follow or accompany an assignment abroad. If an employee can succeed in a difficult assignment overseas, superiors will have greater confidence in his or her ability to manage back in the United States where cross-cultural considerations and foreign language issues are becoming more and more common.

Thanks to a variety of relatively inexpensive communications devices with business applications, even small businesses in the United States are able to get into international markets.

English is still the international language of business. But there is an ever-growing need for people who can speak another language. A second language isn’t generally required to get a job in business, but having language skills gives a candidate the edge when other qualifications appear to be equal.

The employee posted abroad who speaks the country’s language has an opportunity to fast-forward certain negotiations, and can have the cultural insight to know when it is better to move more slowly. The employee at the home office who can communicate well with foreign customers over the telephone or by fax machine is an obvious asset to the firm.

1.With the increased use of high-tech communications equipment, businesspeople ________.

A. are eager to work overseas

B. have to get familiar with modern technology

C. are gaining more economic benefits from domestic operations

D. are attaching more importance to their overseas business

2.In this passage, “out of sight and out of mind” (Line 3, Para. 3) probably means ________.

A. leaving all care and worry behind

B. being unable to think properly for lack of insight

C. being totally out of touch with business at home

D. missing opportunities for promotion when abroad

3.According to the passage, what is an important consideration of international corporations in employing people today?

A. Ability to speak the customer’s language.

B. Connections with businesses overseas.

C. Technical know-how.

D. Business experience.

4.The advantage of employees having foreign language skills is that they can ________.

A. fast-forward their proposals to headquarters

B. better control the whole negotiation process

C. easily make friends with businesspeople abroad

D. easily find new approaches to meet market needs

Has been a dream for 30 years but now the world’s first flying car is set to hit the roads this year.

Ever since the “Back to the Future” movies lit up our screens in the 1980s, designers have dreamt of cars that could take to the sky at the push of a button(按钮). And now pilots can order their own “roadable” plane for just￡127, 000.

The plane, which has fold-out wings that span 17. 5 feet, can be up to 115 mph. Back on the land, it can also travel at “highway speeds” in car mode(模式).

Fuelling(加燃料)the 19 feet long plane couldn’t be simpler—you just drive it into a petrol station and fill it up.

A spokeswoman said, “You can keep your ‘light-sport airplane’ in your garage. But because it needs a short runway to take to the air, you will have to drive to your local airport, fly up to 460 miles, land and drive directly to your destination(目的地). You will always be ready to drive or fly. ”

The spokeswoman added, “Never let bad weather change your trip. You can simply divert(使转向)and continue on the ground until the weather clears. ”

There’s no risk to you—this is only the chance for you to be the first at your home field to unfold(展开)your wings and fly into the future.

The flying car has been talked about for many years, but now it appears to become a reality.

An international company has built a two-seater plane that, at the touch of a button, transforms into a car perfectly suitable for driving on public roads. It takes 15 seconds to switch between flying and driving. With its wings fully open and the propeller(螺旋桨) spinning, it can take off from any airfield.

Flying cars are quicker than traditional ones, and they can run on ordinary fuel. Another big advantage is that they are cool, like something you would see in an action film. At the moment, however, the flying car’s wheels are illegal to leave the ground. That is not because of technical reasons or problems with the design. It is because the various road and aircraft authorities simply cannot agree on whether it is a car or a plane.

Nevertheless the company hopes to produce and deliver its first flying car soon. The company already has orders for 40 of them. The majority potential customers are older and some are retired. There have even been orders from some people who have no pilot’s license.

The flying car will cost around $ 200,000. “For an airplane, that’s a very reasonable price, but for a car, it’s quite expensive,” explains Alan. “But it just is not possible to make a $ 10,000 flying car yet.”

This latest means of transport will not become a mass-market item in the near future, but in the long term it has the potential to change the way you travel. It will become no more expensive than driving your car on the motorway. Travel time could be reduced by more than half.

So the next time you are told to fasten your seat belt, it may be to prepare for take-off.

1.We know from the passage that the flying car 　　　　 .

A. has to run on special fuel

B. will replace traditional planes

C. is popular with the rich

D. can shift between two forms

C

Could the solution to world future energy needs lie in the ocean? It’s possible.

We are not talking about oil, but another potential untapped energy resource called “methane hydrates”.

Methane hydrates are hard, ice-like white solids that form naturally in deposits (沉积物) on ocean floors. They arecomposed of water and highly concentrated methane produced by the microorganisms living in the deposits.

The remarkable thing is that you can hold a flame to a piece of methane hydrate and it will catch on fire. It’s been called “burning ice.”

Methane hydrates are spread around the world. These deposits may in the future become a very important fuel resource. One researcher calculated that a small area off the Southeastern coast of America may contain methane hydrates equal to 30 times the annual U.S. consumption of natural gas.

Right now there are very significant technical and financial challenges facing us before we could exploit this as a resource. Scientists around the world are studying these challenges. One big issue is how to get these methane hydrates off the ocean floor, causing undersea landslides and tidal waves.

Another issue is how to handle the matter after it is brought up. It’s also unclear whether it would make more sense to “mine” solid hydrates or tap the gases found with them. And many deposits may occur in low concentrations with no commercial potential.

Japan, which has no oil supplies of its own, has thrown itself into burning ice research because it has deposits off its shores which could make Japan less dependent on foreign suppliers of oil.

The U.S. Department of Energy and Congress are also supporting research. However, the US administration’s energy policy is focused on traditional fossil (化石) fuels. And at least for now, developing burning ice into a fuel source isn’t high on the energy industry’s list. But if natural gas continues to rise in price, exploiting burning ice might become economically practical.

59. What’s the meaning of the underlined word in Paragraph Two?

A. not existed              B. Unseen         C. available but not used              D. unreal

60. What can you learn from the text?

A. Burning ice has been used in some countries.

B. Applying burning ice tops the energy list in America.

C. Burning ice exists in few countries.

D. There are still some problems in developing the burning ice

61. Why has Japan already begun to develop the burning ice?

A. It is a developed country.  B. They want to help other countries.

C. It lacks oil supplies of its own. D. America asked Japan to do so.

62. Which one is the best title of the text?

A. World Energy Shortage           B. Burning Ice Holds Hope as Fuel Source

C. Methane Hydrates               D. Methane Hydrates Spread around the World

The Crowne Plaza Copenhagen Towers has been named the greenest one in the world by the travel and tourist organization Skaal International, reported the Danish news agency Ritzau on Monday.

The hotel has been awarded the EcoTourism Award for setting an environmental-friendly example to other hotels, said the report.

The Crowne Plaza Copenhagen Towers is located in the Copenhagen suburb of Oerestad and has the largest solar cell facility in the Nordic. This facility delivers energy to the hotel while Danish groundwater supplies cooling and heating in the air condition of the hotel.

The Crowne Plaza Copenhagen Towers

TV and lights in the hotel are all of energy-saving brands. Shampoo bottles, toothbrushes and washing accessories are biologically degradable, which means that the nature can easily absorb the materials.

The hotel restaurant is only buying local goods and the food leftovers are used for bioenergy as well as fertilizer. The fitness facilities also provide a green touch to the hotel, as the training bikes of the fitness center are linked to the power grid（电网） of the hotel, thereby providing free energy if any guest wishes to exercise. People who do contribute free energy this way are supposedly getting a free meal in the hotel restaurant. “It is the first time that a Danish hotel receives this award. I think our throughout green thinking is the reason why we have been awarded. It is all the small details, as well as the big picture，” says Allan Agerholm, the CEO of the hotel, in a press release.

Artificial intelligence, or AI, has slowly begun to influence higher education around the world. Now, one new AI tool could change the way university students evaluate their professor. The tool is called Hubert, a teacher evaluation tool that appears as an AI-powered chatbot. Instead of filling out a form, students use a chat window to give feedback(反馈) on the course and their professor. Afterwards, Hubert categorizes the students’ comments for the professor to review.

Hubert is free for educators to use. More than 600 teachers have used it already. The goal of the new Hubert program is to improve education by giving teachers detailed, organized feedback from students.

Viktor Nordmark, from Sweden, started the company in 2015, with several friends. Before creating Hubert, the founders asked teachers what would improve their teaching skills. The answer, Nordmark said, was qualitative(定性的) feedback from their students. In other words, teachers wanted students to write detailed answers to open-ended questions about their experiences in class.

Qualitative feedback is different from the survey responses, which students are often asked to provide at the end of a class. “This kind of data takes a lot of time for professors to collect and analyze,” Nordmark said. And for the students, it can also be “really boring to fill out.” So Nordmark and his friends designed Hubert as a compromise between a traditional survey and a personal interview. “You can reach a really large crowd, but you can also get really qualitative data back,” Nordmark said.

Now, when Hubert receives comments from students, it compares them with the information already in its system to organize the data. Nordmark says that Hubert will continue to get smarter as it receives more comments in the future. Nordmark says he and his co-founders have plans to make Hubert more flexible and accurate. They hope to give teachers the possibility of selecting their own evaluation questions.

1.What can be inferred about traditional teacher evaluation?

A. Its data is easy to collect

B. Users are charged for using it

C. Students needn’t fill out forms

D. Students find it dull to take part in it

2.According to the text, qualitative feedback　　　 .

A. can improve the students’ performance at school

B. is students’ answers to teachers’ questions in class

C. can be obtained by asking students to fill out forms

D. is detailed responses to questions not for fixed answers

3.What is one of the advantages of Hubert at present?

A. Being able to change itself to become smarter

B. Saving much time when collecting survey forms

C. Taking on the strengths of a survey and an interview

D. Enabling teachers to select their own evaluation questions

4.What is the text mainly about?

A. The characteristics of qualitative feedback

B. A new AI-powered tool of teacher evaluation

C. The changes in the way teachers are evaluated

D. A potential revolution in the educational system
