Computers might not be clever enough to trick adults into thinking they are intelligent yet, but a new study, led by Javier' Movellan at the University of Califomia San Diego, shows that a giggling (咯咯笑的) robot is clever enough to get toddlers (初学走路者) to treat it as a peer (同龄人).

The researchers stationed a 2-foot-tall robot Called QRIO in a classroom of a dozen toddlers aged between 18 months and two years. QRIO stayed in the middle of the room using its sensors (传感器) to avoid bumping (碰撞) into the kids. It was programmed to giggle when the kids touched its head, to occasionally sit down, and to lie down when its batteries died.

"We expected that after a few hours, the magic was going to disappear," Movellan says.  "That's what was found with earlier robots." But, in fact, the kids remained interested in the robot over several weeks, eventually communicating with QRIO in much the same way they did with other toddlers.

The researchers measured the relationship between the children and the robot in several ways. Firstly, as with other toddlers,  they touched QRIO mostly on the arms and hands, rather than on the face or legs. For this age group, "the amount of touching is a good predictor of how you are doing as a social being," Movellan says.

The children helped the robot up when it fell, and when QRIO's batteries ran out and it lay down, a toddler would come up and cover it with a blanket and say "night, night". However, when QRIO was programmed to spend all its time dancing, the kids quickly lost interest. When the robot went back to its old self, the kids treated it like a peer again.

"The study shows that current technology is very close to being able to produce robots able to develop a special relationship with toddlers," says Movellan. But, he adds, it is not clear yet whether robots can interest older children or adults in the same way.

1.What does the underlined word  "stationed" in Paragraph 2 probably mean?

A. Hid.     B. Observed. C. Placed.   D. Named.

2.At the beginning of the experiment, researchers ________.

A. feared that the robot would harm the toddlers

B. programmed the robot to move freely about the classroom

C. expected the robot to communicate with the toddlers

D. thought the toddlers' interest in the robot wouldn't  last long

3.Kids aged between 18 months and two years behave

as social beings by.

A. giggling  B: touching  C. toddling  D. dancing

4.What would be the best title for the passage?

A. Giggling robot becomes one of the kids

B. Giggling robot used as a classroom assistant

C. Giggling robot makes kids more active in class

D. Giggling robot attracts more attention from kids

A breathtaking trick potentially left over from our ancestors might be found in us — the ability to sense oxygen through our skin.

Amphibians, animals such as frogs that can live both on land and in water, have long been known to be capable of breathing through their skin. In fact, the first known lungless frog that breathes only through its skin was discovered recently in the rivers of Borneo.

Now the same oxygen sensors found in frog skins and in the lungs of mammals (哺乳动物) have unexpectedly been discovered in the skin of mice.

“No one had ever looked,” explained Randall Johnson, a biologist researcher.

Mice and frogs are quite distant relatives, so the fact they have these molecules (分子) in common in their skin suggests they might well be found in the skin of other mammals, such as humans.

“We have no reason to think that they are not in the skin of people too,” Johnson said.   These molecules not only detect oxygen, but help increase levels of vital red blood cells, which carry oxygen around the body. Normal mice breathing in air that is 10 percent oxygen—a dangerously low level similar to conditions at the top of Mount Everest, and about half that of air at sea level. However, mice that had the oxygen sensor HIF-1a genetically removed from their skin failed to produce this hormone (荷尔蒙) even after hours of such low oxygen.

These findings, if they hold true in humans, suggest one could raise the level of oxygen circulating inside the body. This could help treat lung diseases and disorders such as anemia (贫血症) without injecting drugs, which make up a multibillion-dollar market, Johnson said.

Athletes also often try to get more oxygen delivered to their muscles in order to improve their performance. They often do this by training at high altitudes or in low-oxygen tents. The new study suggests they might want to expose their skin as well as breathing in low-oxygen air to improve their performance. “It’s hard to say what exactly might be done, however—there’s a lot we don’t know yet,” Johnson explained.

The scientists detailed their findings in the April 18 issue of the journal Cell.

49. Which of the following statements is TRUE according to the passage?

A. Johnson believes that Oxygen sensors also exist in human skin.

B. People have to surf the Internet to read detailed findings.

C. It has been proved that these findings help treat lung diseases.

D. It has long been expected oxygen sensors exist in mice’s skin.

50. One of the functions of the molecules mentioned above is _______.

A. carrying oxygen around the body                   B. improving athletes’ performance

C. detecting oxygen                                          D. increasing level of oxygen

51. What is Johnson’s attitude to the application of the findings to the athletes’ training?

A. Negative                  B. Doubting                  C. Positive             D. Hesitating

52. The best title of the passage may be _______.

A. Great Findings Benefits Athletes A Lot

B. Frogs And Mice Are Distant Relatives

C. First Known Animal Breathes Through Skin

D. Humans Might Sense Oxygen Through Skin

Yang Li, a five-year-old girl living next door to me, very clever. Because she is not old enough to go to the school, she often asks me to teach herself to read, write and draw. She studies hardly and soon she learns a lot. One evening last month I was doing my English homeworks when she came to my house. She asked me how I learned English. “You would find English a bridge for so much knowledge,” I said. She then wanted to learn English, either. She has learned many English words so far but her parents are very grateful to me.

Electric cars are dirty. In fact, not only are they dirty, but they might even be more dirty than their gasoline-powered cousins.

People in California love to talk about “zero-emissions (排放) vehicles”, but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Apart from the few people who have their roofs covered with solar cells, we get our electricity from generators (发电机). Generators are fueled by something----usually coal, oil, but also by heat generated in nuclear power plants. There are a few wind farms and geothermal (地热) plants as well, but by far we get electricity mainly by burning something.

In other words, those “zero-emissions” cars are likely coal-burning cars. Because the coal is burned somewhere else, it looks clean. It is not true. It's as if the California Greens are covering their eyes----“If I can't see it, it's not happening.” Gasoline is an incredibly (极其) efficient way to power a vehicle; a gallon of gas has a lot of energy in it. But when you take that gas (or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat--at the generator, through the transmission lines, etc.

A gallon of gas may drive your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far---so electric cars burn more fuel than gasoline-powered ones. If our electricity came mostly from wind or geothermal, or solar, then an electric car truly would be clean. But for political, technical, and economic reasons, we don't use much of those energy sources.

In addition, electric cars' batteries which are poisonous for a long time will eventually end up in a landfill (垃圾填埋场). And finally, when cars are the polluters, the pollution is spread across all the roads. When it's a power plant, though, all the junk is in one place. Nature is very good at cleaning up when things are not too concentrated, but it takes a lot longer when all the garbage is in one spot.

1.Which of the following words can replace “be clueless about” in Paragraph 2?

A. be familiar with.　　　　　　　　　　　　　 B. fail to understand.

C. be curious about.　　　　　　　　　　　　　 D. show their interest in.

2.The electricity we get from a gallon of gas may make our car run _________.

A. at least 25 miles　　　　 　　　　　　　　 B. more than 25 miles

C. less than 25 miles　　　　　　　　　　　　 D. as far as 25 miles

3.In the author’s opinion, compared with cars using gas, electric cars are more __________.

A. harmful　　　　　　　　　　　　 　　 B. expensive

C. efficient　　　　　　　　　　　　　　 D. environmentally-friendly

4.It can be inferred from the passage that __________.

A. electric cars’ batteries are no longer poisonous in the landfill

B. electric cars are not clean since we get electricity mainly by burning something

C. zero-emissions vehicles should be chosen to protect our environment

D. now electric cars are used more than their gasoline-powered cousins

Do you really know who you are? This is not a trick question but rather an honest understanding into the inner workings of each one of us. We usually share with our friends a piece of who we are, the piece that we want them to like or connect with. However, there is a secret, a hidden piece that doesn’t want to be noticed by others.

Our personal inner beliefs play a vital role in the way we think, act and live. They set us up to accept a belief and then it is the belief that separates our personal story. There are numerous people who have taken on the pain and suffering of their parents. Some have devoted their lives to living with lack; that is lack of love because they saw what they thought was love while in the crib (婴儿床) and it frightened them. Subconsciously (潜意识地) they made great efforts in their lives to avoid a similar experience.

Each one of us carries around with us our inner beliefs. If one of your beliefs is one that causes you to hold back from getting the perfect job or blocking love to come to you, that belief is a negative belief and one that needs to be dealt with if you are seeking a life of joy, contentment and personal success, whether it is emotional, spiritual, financial or physical.

Don’t let your blocked or frozen emotions guide the way you want to lead your life. Now it is your time to finally become victorious over those past situations that have upset you during your entire life and become the winner you were born to be.

1.What is the author’s purpose with a question at the beginning?

A. To explain who we are really.

B. To introduce the main topic.

C. To show the author’s opinion.

D. To persuade people to share inner beliefs.

2.We can infer that the author believes inner beliefs ________.

A. shape us　　 B. block love to come

C. shouldn’t be hidden　　 D. make us sad and painful

3.What does the underlined word “it” in the third paragraph refer to?

A. The love to come.

B. The negative belief.

C. The past painful experience.

D. The life of joy, contentment and personal success.

4.Which of the following is the suggestion of the author?

A. Sharing our inner beliefs with others.

B. Ignoring blocked or frozen emotions.

C. Dealing with our negative inner beliefs wisely.

D. Having a deep understanding of our inner beliefs.

Foreign visitors to the UK might be disappointed when they learn that not everyone there speaks like Harry Potter and his friends. Usually, there’s an assumption by many non-Brits that everyone in Britain speaks with what’s known as a Received Pronunciation (RP, 标准发音) accent, also called “the Queen’s English”. However, while many people do talk this way, most Britons speak in their own regional accents.

Scouse, Glaswegian and Black Country – from Liverpool, Glasgow and the West Midlands – are just three of the countless non-RP accents that British people speak with. There are even differences in accents between towns or cities just 30 kilometers apart. What is even more disappointing is that not speaking in a RP accent may mean a British person is judged and even treated differently in their everyday life.

In a 2015 study by The University of South Wales, videos of people reading a passage in three different UK accents were shown to a second group of people. The group then rated how intelligent they thought the readers sounded. The lowest-rated accent was Brummie, native to people from Birmingham, a city whose accent is considered working class.

However, there is no need to be disappointed though you are not speaking in an RP accent. In fact, doing the opposite may even give you strength.

Kong Seong-jae, 25, is an internet celebrity from Seoul. After studying in the UK, he picked up several regional accents. He’s now famous for his online videos, where he shows off the various accents he’s learned. “British people usually get really excited when I use some of their local dialect words, and they become much friendlier. I think it makes a bit of bond between local people and foreigners to speak in their local accent,” he said.

So if you’re working on perfecting your British accent, try to speak like someone from Liverpool, Glasgow or Birmingham. You may not sound like Harry Potter, but you are likely to make more friends.

1.What can we infer from paragraph 1?

A. Only “the queen’s English” is accepted in the UK.

B. Non-Brits usually hold that all Britons speak in a RP accent.

C. Foreign visitors are disappointed at their own spoken English.

D. Any Received Pronunciation around the world is also called “the Queen’s English”.

2.What do people think of the Brummie accent?

A. Closest to the RP accent.　　 B. Spoken by people of lower class.

C. Smart and easy to understand.　　 D. Favored by foreign visitors to the UK.

3.What does the underlined phrase “doing the opposite” in Paragraph 4 refer to?

A. Speaking in regional accents.　　 B. Speaking in a RP accent.

C. Speaking the Brummie accent.　　 D. Speaking like Harry Potter.

4.What is the passage mainly about?

A. How much British people value the RP accent.

B. A comparison between different British accents.

C. The impact of regional accents on people’s lives.

D. A study about the most intelligent accent in Britain.
