Transport has a lot to answer for when it comes to harming the planet．While cars and trains are moving towards greener，electric power，emissions from air travel are expected to increase massively by 2050．If we want big green sky solutions，we need blue sky thinking．Fortunately，there's plenty of that happening right now，particularly the short﹣haul flights powered by batteries．
Harbour Air is the largest seaplane airline in North America，flying 30，000 commercial flights in 40 seaplanes each year．Significantly，all Harbour Air routes last less than 30 minutes，making it perfectly fit for electric engines．"As an airline，we're currently in the process of turning all our planes into electric airplanes．" says CEO Greg McDougall．To make this happen，the airline has partnered up with MagniX to create the world's first commercial flight with an electric engine．
Making the skies electric isn't just good for the environment，it also makes sound financial sense：a small aircraft uses ﹩400 on conventional fuel for a 100﹣mile flight，while an electric one costs ﹩8﹣ 12 for the same distance，and that's before you factor in the higher maintenance costs of a traditional engine．There's also the added bonus that electric planes are just much more pleasant to fly in．No loud engine noise，no smell of fuel，just environmentally friendly peace and quiet．
While there has been real progress in the e﹣plane industry，the technical challenges that remain are keeping everyone's feet firmly on the ground．A battery，even a lithium one，only provides 250 watt﹣hours per kilogram；compare this to liquid fuel，which has a specific energy of 11，890 watt﹣hours per kilogram．Carrying adequate batteries， however，would make the plane too heavy to get off the ground．In aircraft，where every bit of weight counts，this can't just be ignored．
The transition（过渡） from gas to electric in the automobile industry has been made easier by hybrids﹣ vehicles powered by both fuel and electricity．Many believe the same pattern could be followed in the air．Fuel consumption could be reduced as the electric component is switched on at key parts of the journey，especially on take﹣off and landing．
It's certainly an exciting time for electric flying．With companies like Harbour Air taking the lead，battery﹣powered planes，especially on short﹣haul journeys，are set to become a reality in the next few years．

When TV news programs report wars or disasters, the editors rarely use the most horrifying pictures of dead or wounded victims because they don’t want to upset their viewers. Even so, viewers are usually warned in advance that they may find some of these scenes disturbing, so they can look away if they choose. But the men and women whose job is to record those scenes－the TV cameramen－have no such choice. It is their duty to witness the horrors of the world and record them, no matter how terrible and unpleasant they may be. Consequently, it is one of the most dangerous, exposed and emotionally taxing jobs the world has to offer.
Today, the demand for their work is rising. The explosion of satellite broadcasting and 24-hour news in recent years has created an almost insatiable (贪得无厌的) demand for TV information. But major broadcasters and the TV news agencies—such as Reuters and WTN－have never had enough staff to meet the worldwide demand for up-to-date pictures, so increasingly they turn to “freelance” TV cameramen.
These freelance cameramen are independent operators tied to no particular organization. They will work for any company which hires them, be it for just a few hours or for several weeks in a war zone. But if the freelance cameraman is injured in the course of the job, the TV company is not responsible for him. The freelancer must survive on his own.
TV will always need hard, vivid moving pictures which are fresh, but these companies feel uncomfortable with large numbers of employees on their books, explains Nick Growing, once foreign editor for Britain Channel 4 News and now a BBC news presenter.
By hiring freelancers, they can buy in the skills they need only when they need them. It also enables them to contract out the risk, he says.TV news agencies turn to freelance cameramen in order to .
| A．save expense and avoid risks |
| B．get free and useful pictures |
| C．get first-hand information and pictures |
| D．satisfy the greed of the freelance cameramen |
We can infer from the passage that the freelance cameramen .
| A．have to take a lot of risks in the course of work |
| B．are tied to many TV news agencies |
| C．have better skills than other cameramen |
| D．need to contract out risks of work for TV companies |
According to this passage, some major broadcasters and TV news agencies .
A. have employed enough cameramen
B. are not willing to employ many cameramen
C. are very mean to freelancers
C. are responsible for the freelancer if he is injuredThe author of this passage shows his the freelance cameramen.
| A．sympathy to | B．respect for | C．anger to | D．admiration to |
Surrounded by the towns of Davidson, Huntersville and Cornelius, Lake Norman is a man-made lake. It is also the largest lake in the state covering a shoreline of more than 500 miles. State Park on the lake gives a chance for different water activities.
People, both tourists and locals, come to the area on weekends, where during the peak season a large crowd arrives to relax and have fun. A great activity for kids is education except fun.

When I was young, I had an old neighbor named Dr. Gibbs. He didn’t look like any doctor I’d ever known. He never shouted at us for playing in his yard. I remembered him as a neighbor who was nicer than anyone else in the neighborhood.
When Dr. Gibbs was happy, he was planting trees. And his life’s goal was to make it a forest.
Dr. Gibbs had some interesting theories about planting. He talked about trees that weren’t watered would grow deep roots in search of water. So he never watered his trees. He planted an oak (橡树) and, instead of watering it every morning, he beat it with the rolled-up newspaper. I asked him why he did that, and he said it was to get the tree’s attention.
Dr. Gibbs died a couple of years. Every now and again, I walk by his house and look at the trees that he planted twenty-five years ago. They’re very strong now.
I planted a couple of trees a few years later. I watered them regularly and took good care of them. Whenever a cold wind blows, they shake their leaves and branches.
The funny thing about those trees of Dr. Gibbs was that difficulty seemed to help them in ways comfort and ease never could.What was Dr. Gibbs’ life goal?
| A．To build a forest. | B．To save more lives. |
| C．To make a lot of money. | D．To study plants. |
One of Dr. Gibbs’ theories about planting was that ______.
| A．he often talked to the trees | B．he kicked the trees heavily |
| C．he never watered the trees | D．he buried the leaves around the roots |
What does the writer mainly want to tell us?
| A．Trees are not as weak as we think. |
| B．We should listen to others’ advice. |
| C．Difficulty is necessary for growth. |
| D．Planting trees is good for the environment. |
Streit was an experienced safecracker who never used force —either against people or safes (保险箱). He was a real artist of his trade and it took him only 19 minutes to open the most difficult safe he had ever encountered. In about 10 years, helped by his brother Stefan and two friends, he took about $330,000 —from the safes of 28 banks in Austria. On his last job, early in 1999, he left the safe door open and $80,000 behind. With the money ws a note, "We don’t need all that much." A witness (目击者) recognized his car and Streit was caught by the police. Then he was sent to Austria’s Stein Prison to serve a six-year sentence. He boasted (吹嘘) at his trial that he would continue breaking the law, "I am a thief and I shall use every opportunity." Despite the warn-ing, prison officials moved Streit to the prison’s blacksmith (铁匠) shop. One day during the week before Christmas, Streit disappeared. Searchers found all his doors were well locked. Streit had managed to make a set of keys and let himself out. Not to freedom, though. After crossing into Bavaria, Streit attracted the suspicion (怀疑) of German customs police on purpose and got himself arrested. "I want to be in a German prison,"he explained to the surprised police. "As German courts give much milder (温和的) sentences for crimes like mine and will reduce the time I would otherwise have served in Stein Prison." In prison, Streit persuaded his keepers to let him make a Christmas Eve telephone call to his former keeper, Karl Schreiner of Stein Prison. "I’m sorry if I caused trouble. I didn’t want to embarrass anybody by escaping. Conditions weren’t that bad. In fact the food was better than it is here."The underlined word "safecracker" in the first paragraph means "_________".
| A．prisoner | B．criminal | C．stealer | D．Robber |
