Robots make me nervous—especially the ones which seem to think for themselves. I was embarrassed to admit this till I heard that Bill Gates, the founder of Microsoft, felt the same way.

Gates said in an interview with the social networking and news website Reddit: “I am in the camp that is concerned about super intelligence. First the machines will do a lot of jobs for us and not be super intelligent.That should be positive if we manage well. A few decades after that though the intelligence is strong enough to be a concern.”

Well, maybe I don’t have to worry about my computer and kitchen equipment yet. After I use them I can always pull the plug. But in the future, machines might find a way to prevent us from switching them off. There’s a terrible thought!

Maybe the problem with computers too clever for us is not that they are evil like some we’ve seen in sci-fi movies. What could put us in danger is that they might be too efficient. That’s what philosopher Nick Bostrom from Oxford University believes. He says that machines are indifferent (漠然) to humans and in pursuit of their own goals,the destruction of people might be just additional damage. Bostrom gives us an example: A machine which might have as its only goal to produce as many paperclips as possible might look at human bodies as extra material for paperclips and go after you. Because it is, well, a machine, it would not take pity on you.

It’s a good thing that American writer Isaac Asimov thought about how far robots can go and left us his three rules of robotics. They state that a robot may not hurt a human being or allow the human being to come to harm.

I’m glad my machines at home are “dumb”. All my cleaner wants to take over is the carpet in my living room. Let’s hope they don’t create an appliance which wants to take over the world!

In 1971 a young man who grew up very poor was travelling across the country, trying to make a new start for himself. Along the way he had completely run out of(用光) money and was forced to spend the night in his car. This continued until one morning, after a week of sleeping in his car, he walked nervously into a restaurant and ordered a big breakfast.

After eating his first good meal in weeks, he found himself lying to the waiter, telling him he had lost his wallet. The waiter, who was also the owner, walked behind the chair where the young man had been sitting. He bent down, and came up with a $20 bill that looked as if it had fallen on the floor and said, “Son, you must have dropped this,” the owner said. The young man couldn’t believe his luck! He quickly paid for the breakfast, left a tip, bought gas with the change, and headed West.

On the way out of town, he began to understand what the owner did. Maybe nobody dropped the money at all. “Maybe that fellow just knew I was in trouble and he helped me in a way that didn’t embarrass(使尴尬) me. So I just made a promise to help other people if I can.”

Later, he worked very hard and became a rich man. Now he lives near Kansas City. Each year he gives away thousands of dollars. He is known as the “Secret Santa” because at Christmas time each year, he personally hands money out to those on the street and at restaurants. Last year, he gave more than $50,000 away in Kansas City.

The Healthy Habits Survey shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.

1. How many times did you brush your teeth yesterday?

● Finding: A full 33% of seniors brush their teeth only once a day.

● Step: Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes at least twice a day.

2. How many times did you wash your hands or bathe yesterday?

● Finding: Seniors, on average, bathe fewer than 3 days a week. And nearly 30% wash their hands only 4 times a day---half of the number doctors recommend.

● Step: We touch our faces around 3,000 times a day-often inviting germs(病菌)to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.

3. How often do you think about fighting germs(病菌)?

● Finding: Seniors are not fighting germs as well as they should.

● Step: Be aware of germs. Do you know it is not your toilet but your kitchen sponge (海绵) that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.

The Canadian red and white maple leaf(枫叶) flag is officially called the National Flag of Canada. The Canadian flag shows a stylized red maple leaf with 11 points on a white background, with red borders down each side. The Canadian flag is twice as long as it is wide. The white square containing the red maple leaf is the same width as the flag.

The red and the white used in the National Flag of Canada were proclaimed the official colors of Canada in 1921 by King George Ⅴ. Although the maple leaf did not have its official status as a symbol of Canada until the announcement of the national flag in 1965, it had historically been used as a Canadian symbol, and was used in 1860 in decorations for the visit of the Prince of Wales to Canada. The 11 points on the maple leaf have no special significance.

In the early days,the Royal Union Flag,or the Union Jack, was still flown in British North America. In 1925 and again in 1946, the Canadian Prime Minister Mackenzie King tried to get a national flag of Canada adopted, but failed. In 1964,Prime Minister Lester Pearson appointed a 15-member, all-party committee to come up with a design for a new flag. The committee was given six weeks to complete its task.

The committee studied 2,000 submitted(提交的) designs as well as 3,900 that had been gathered as a result of the 1946 committee's study. Those designs with a chance of being accepted were given to the full committee for further study.

The suggestion of a red and white single maple leaf design for the Canadian flag came from George Stanley, a professor at the Royal Military College. After a heated discussion, they finally decided on his suggestion.

1.How many colors are there in the National Flag of Canada?

A.One.B.Two.C.Three.D.Four.

2.When did Canada have its own national flag?

A.In 1921.B.In 1860.C.In 1964.D.In 1965.

Energy independence. It has a nice ring to it. Doesn’t it? If you think so, you’re not alone, because energy independence has been the dream of American president for decades, and never more so than in the past few years, when the most recent oil price shock has been partly responsible for kicking off the great recession.

“Energy independence” and its rhetorical (修辞的) companion “energy security” are, however, slippery concepts that are rarely though through. What is it we want independence from, exactly?

Most people would probably say that they want to be independent from imported oil. But there are reasons that we buy all that oil from elsewhere.

The first reason is that we need it to keep our economy running. Yes, there is a trickle(涓涓细流)of biofuel available, and more may become available, but most biofuels cause economic waste and environmental destruction.

Second, Americans have basically decided that they don’t really want to produce all their own oil. They value the environmental quality they preserve over their oil imports from abroad. Vast areas of the United States are off-limits(禁止) to oil exploration and production in the name of environmental protection. To what extent are Americans really willing to endure the environmental impacts of domestic energy production in order to cut back imports?

Third, there are benefits to trade. It allows for economic efficiency, and when we buy things from places that have lower production costs than we do, we benefit. And although you don’t read about this much, the United States is also a large exporter of oil products, selling about 2 million barrels of petroleum products per day to about 90 countries.

There is no question that the United States imports a great deal of energy and, in fact, relies on that steady flow to maintain its economy. When that flow is interrupted, we feel the pain in short supplies and higher prices, At the same time, we derive(得到,获得) massive economic benefits when we buy the most affordable energy on the world market and when we engage in energy trade around the world.

1.What does the author say about energy independence for America?

A. It sounds very attractive.

C. It will bring oil prices down.

B. It ensures national security.

D. It has long been everyone’s dream.

2.Why does America rely heavily on oil imports?

A. It wants to expand its storage of crude oil.

B. Its own oil reserves are quickly running out.

C. It wants to keep its own environment intact.

D. Its own oil production falls short of demand.

3.What is the author’s purpose in writing the passage?

A. To arouse Americans’ awareness of the energy crisis.

B. To stress the importance of energy conservation.

C. To explain the increase of international oil trade.

D. To justify(证明… 有理的) America’s dependence on oil imports.

Paying a higher price than usual for a ticket to see a film in 3D is the annoyance of many a cinema-goer’s life.

But there may be a benefit to doing so, as a study has found that 3D films exercise the brain and improve short-term functioning in a similar way to brain-training tests.

The research found that people who watched a movie in 3D improved cognitive (认知) skills, compared to those who watched it in 2D.

The research was led by neuroscientist(神经学家) Dr Patrick Fagan from Goldsmiths University in London. More than 100 people took part in the experiment, where participants watched Disney film Big Hero 6 in either standard format or RealD 3D.

They also carried out a brain-training-style test before and after seeing a section from the film. The test covered memory, reaction times and cognitive function and the results were compared later.

According to the research, which was carried out in partnership with science group Thrill Laboratory, participants experienced a 23 percent increase in cognitive processing, as well as an 11 percent increase in reaction times.

Dr Fagan said that the results showed enough of an improvement in brain function to suggest that 3D could play a part in improving brain power in the future.

“These findings are more significant than you might think,” he said. “It is a fact that people are living longer and there is a noticeable decline in cognitive brain function in old age which can worsen future quality of life. There has never been a better time to look at ways to improve brain function. The initial results of this study show that 3D films may potentially play a role in slowing this decline.”

A second part of the experiment involved those watching the film being fitted with headsets that scanned brain activity and this too showed heightened (加强的) activity when watching 3D. According to the results, participants were seven percent more engaged with what they were watching, adding to argument that 3D movies are more like watching real-life—something Professor Brendan Walker from Thrill Laboratory agreed with.

“As Professor Brendan Walker’s test concluded, 3D films are more attractive and heighten the senses — this, in turn, makes the brain run at quicker speeds,” Dr Fagan said.
