Kar-go is the invention of the United Kingdom...

Kar-go is the invention of the United Kingdom-based Academy of Robotics, which describes it as”Europe's first road-worthy autonomous delivery vehicle".Using AI, this autonomous delivery vehicle offers customers an app---similar to one used when ordering a taxi- allowing them to choose when and where their packages are delivered. Cormpanies like Tesla and Amazon have invested heavily in autonomous vehicles, which have the potential to create a sea of changes in business and society.

Resembling something like a green egg on wheels, Kar-go's aim is to reduce the cost of what's known as the "last mile delivery challenge" . This is the final stage of your online package's journey ,from a local warehouse to your front door. Labor costs, paying drivers, the cost of fuel and the vehicle costs for maintaining small vehicles all contribute to making this the most expensive part of the delivery process. The first part of the package's journey is far cheaper, with high volumes of packages being transported to and from the same location. However, at the other end, drivers deliver smaller shipments to several different locations where the recipient may not even be available to collect.

With the latest AI technology, Kar-go will deliver goods safely ,sustainably and in style. The AI vehicle uses special technology to become an expert on its own individual route, learning from past experiences in order to help itself deal with new future obstacles(障碍物)on the road. Kar-go also has its very own internal sorting system, allowing the vehicle transport packages in the correct order for delivery.

By 2030，the Society of Motor Manufacturers and Traders predicts the autonomous market could add $ 62 billion in economic growth in the UK, creating more than 420,000 new jobs. Eletric, self-driving, economic and capable of working 24/7，Kar-go promises to reduce the last mile delivery cost by up to 90%，providing an efficient solution to the rapidly-expanding online retail(零售) market.

It was graduation day at Etihad Training Academy，where the national airline of the United Arab Emirates holds a seven-week training course for new flight attendants．

Despite her obvious pride，Ms．Fathi，a 22-year-old from Egypt，was amazed to find herself here．“I never in my life thought I’d work abroad，” said Ms．Fathi，who was a university student in Cairo when she began noticing newspaper advertisements employing young Egyptians to work at airlines based in the Persian Gulf.

Twenty years ago，unmarried Arab women like Ms．Fathi，working outside their home countries，were rare．But just as young men from poor Arab nations poured into the oil-rich Persian Gulf states for jobs，more young women are doing so．

Flight attendants have become the public face of the new mobility for some young Arab women，just as they were the face of new freedoms for women in the United States in the 1950s and 1960s．They have become a subject of social anxiety and fascination in much the same way．

For many families，allowing a daughter to work may call her virtue into question．Yet this culture is changing，said Musa Shteiwi，a sociologist at Jordan University in Amman．“We’re noticing more and more single women going to the gulf these days，” he saiD． “It’s still not exactly common，but over the last four or five years it’s become quite an observable phenomenon.”

Many of the young Arab women working in the Persian Gulf take delight in their status as pioneers，role models for their friends and younger female relatives．Young women brought up in a culture that highly values community，have learned to see themselves as individuals．The experience of living independently and working hard for high salaries has forever changed their beliefs about themselves，though it can also lead to a painful sense of separation from their home countries and their families.

—From New York Times (December 22，2014)

The 2016 Nobel Prize in Physics is shared by three scientists, the Royal Academy of Sciences announced in Stockholm on Tuesday. The Nobel Prize in Physics 2016 was divided, with one half awarded to David J. Thouless, the other half to F. Duncan M. Haldane and J. Michael Kosterlitz “for theoretical discoveries of topological phase transitions and topological phases of matter(物质拓扑相变和拓扑相).”

Haldane said he was “very surprised” at the news, adding that he was glad that their discoveries found something previously unnoticed by many, and that they revealed “more possibilities for looking for new materials.” He particularly pointed out that a lot of work was still ongoing.

The year’s prize amount is 8 million Swedish krona(0.93 million US dollars), and will be split properly between the three winners.

The winners are given a sum of money when they receive their prizes, in the form of a document confirming the amount awarded. The amount of prize money depends upon how much money the Nobel Foundation can award each year. The purse has increased since the 1980s, when the prize money was 880,000 SEK per prize. In 2009, the monetary award was 10 million SEK (US$1.4 million; €950,000). In June 2012, it was lowered to 8 million SEK.

If there are two winners of a particular prize, the award money is divided equally between the winners. If there are three, the awarding committee can choose to divide the money equally, or award one-half to one winner and one-quarter to each of the others. It is common for winners to donate prize money to benefit scientific, cultural, or charities.

1.How much price money does Thouless get?

A. 8 million Swedish krona.

Pierre is a 25-year-old penguin at the California Academy of Sciences. Due to his old age, he was going bald, which made him feel too cold to swim in the pool. Therefore, biologists at the academy had a wetsuit created for this penguin to help him get back in the swimming pool.

Unlike marine mammals, which have a layer of fat to keep them warm, penguins depend on their waterproof feathers. Without them, Pierre was unwilling to jump into the swimming pool and ended up trembling on the side of the pool while his 19 peers played in the water.

"He was cold; he would shake," said Pam Schaller, a senior biologist. Schaller first tried a heat lamp to keep Pierre warm. Then she got another idea: if wetsuits keep humans warm in the cold Pacific, why not make one for Pierre?

Schaller designed the suit, which covered Pierre’s body and had small openings for his flippers.

“I would walk behind him and look at where there were any gaps, and cut and refit and cut and refit until it looked like it was extremely suitable,” she said.

One concern was that the other penguins would reject Pierre in his new suit, but in fact, they accepted his new look. He swam freely and got along with others well, although he was the only penguin with a black stomach.

Schaller couldn’t say for sure whether the wetsuit allowed Pierre to recover his fine feathers, but “certainly we were able to keep him comfortable during a period of time that would have been very difficult for him to stay comfortable”.

Pierre will take off his suit after his new feathers grow back.

1.Pierre felt too cold to swim in the pool because of _____.

A. not having a layer of blubber            B. having few feathers due to old age

C. having no wetsuit                        D. others penguins rejecting him

2.The idea of making a wetsuit for Pierre came from _____.

A. total invention                          B. waterproof feathers

C. the use of wetsuit on humans             D. the use of heat lamp

3.Schaller followed Pierre in order to see _____.

A. whether other penguins would reject him

B. if anywhere of wetsuit needed to be cut and refit

C. if the wetsuit kept warm

D. whether the wetsuit would keep the feathers from recovering

4.The best title of the passage is _____.

A. Wetsuit for An Old Penguin           B. Old Penguin Getting Bald

C. Unwilling to Swim                    D. Strange Look of Pierre

The Internet, as we know, is probably one of the greatest inventions of human history. Never before has the access to the collection of the world’s knowledge ever been more available. 1. Some people look to make use of the information you are providing to the Internet. Everything you do online leaves a small footprint.

There are a couple of steps you can take to make your adventures online a little safer and more secure. Let’s take a look at them.

Cover your tracks.

Whenever you visit a website, a small file is marked in your browser(浏览器), which is called a “cookie”. 2. This enables the webserver to know if you have been there before and it can tailor the presentation to your personal tastes. They are also how Facebook knows to serve you ads based on stuff you looked at on Amazon.

So what’s the harm in the cookie? Well, hackers can use the information stored in your cookies to edit a browsing history or with less secure cookies, take your passwords for some sites. If you want to protect yourself from your information being available to sites then you can turn off the generation of cookies in your browser. 3.

4.

The major browsers, Chrome, Internet Explorer, Firefox, and Safari are all built to be secure from snooping(窥探), but the people who write the code for the browsers are human and they make mistakes.　　 5. These are usually addressed very quickly, but it is important that you make sure your browser is up to date. Just like your operating system, new security patches are being applied all the time, you need to make sure you have them. Turning on automatic updates is something I highly recommend.

A.Use the latest browsers.

B.Change browsers frequently.

C.This will help protect you online.

D.That’s how the cookie works on our computer.

E.This great invention and resource is not without its dangers.

F.It is common for a security problem to pop up with a browser.

G.These cookies store information about who you are and what you looked at.

Mobile phones are one of the most useful inventions of the last 50 years, but not everything that is said about them is good. Mobiles are frequently blamed for a number of things, from thumb injuries and headaches to house fires. 1.

The theory is that the bees navigation (导航) systems are damaged by the radiation that is given off by mobile phones. Bees have a built-in system a bit like GPS and this helps them find their way back to their hive. But recently, thousands of bees have failed to find their way home. 2.

The problem was first noticed by beekeepers in America and is a lot more complicated than it at first seems. The important thing about bees is that most of the crops in many countries of the world are pollinated (授粉) by them. 3. Many beekeepers in America and Europe have reported losing between 50 and 70 percent of their bees. Jim Piper, a London beekeeper, was recently asked how the problem was affecting him. “My business has been ruined by this,” he explained, “twenty-nine of my forty hives are now empty.”

4. However, the fact that bees are disappearing in very large numbers is real. And we can’t manage without them. Einstein said that if all our bees disappeared, man would only live for four more years! 5. If the mobile phone theory is correct, we need to do something about it immediately—before it’s too late.

A. Bees are losing their way.

B. Nobody has proved the theory is true.

C. More evidence is provided to support the theory.

D. It is believed they are dying far from their hives.

E. Without bees, the crops can’t continue to grow.

F. The situation needs to be evaluated by the world’s best scientists.

G. One theory even blames mobile phones for the disappearance of bees.

高三英语单项填空中等难度题查看答案及解析

How men first learned to invent words is unknown, in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds and which could be written down. Those sounds, whether spoken, or written in letters, we call words.

The power of words, then, lies in their association—the thing they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and the sad events of our past; and the more we read and learn, the more the number of words that mean something to us increase.

Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming and telling use of words is what we call literary style. Above all, the real poet is a master of words. He can convey （表达，传递）his meaning in words which sing like music, and which by their position and association can move men to tears. We should, therefore, learn to choose our words carefully and use them accurately, or they make our speech silly and vulgar.（粗俗的）

48. Which of the following about a real poet is NOT true?

A. He is less than a master of words.

B. His style is always charming.

C. His poem can move men to tears.

D. He can express his ideas in words that sing like music.

49. Where does the real power of the words come from?

A. From the words themselves.

B. From their characteristics.

C. From their curiosity.

D. From their association.

50. What is the main idea of the passage?

A. The importance of choosing words.

B. Where the real power of words come from.

C. What great writers are like.

D. We should learn to choose words carefully.
