President Barack Obama has complained about the loss of privacy that comes with being leader of the United States, regretting the loss of simple pleasures such as a long walk or a trip to the car wash or supermarket．
“I just miss -- I miss being anonymous,” he said. “I miss Saturday morning, rolling out of bed, not shaving, getting into my car with my girls, driving to the supermarket, squeezing the fruit, getting my car washed, taking walks. I can't take a walk.”
His dream, he said, was to “go through Central Park and watch folks passing by…spend the day watching people -- I miss that”.
Faced with angry criticism for playing more golf than most previous occupants of the White House, he explained that the sport was simply the best way of getting away from it all. “It's the only excuse I have to get outside for four hours.” he told Hearst magazines．
Though he said he enjoyed his life in the White House, he felt disappointed with some of the ways of Washington, which he has failed in his pledge (誓言) to change, such as the "kabuki dance" among political parties before serious policy discussions begin． His comments may be seen as vindication (证实) by critics who have accused him of appearing too detached (漠然), and being slow to engage in vital issues such as Libya and the near shutdown of the US government last week．
Since arriving at the White House in January 2009, Mr Obama has already racked up 60 rounds of golf in office, more than George W Bush did in his eight years．In terms of ability, Golf Digest magazine has ranked Mr Obama eighth out of the 18 presidents who played the game since it became established in the early 20th century．What do the second paragraph and the third paragraph mainly tell us?

Robots are common in today's world. They manufacture cars, work in space, explore oceans, clean up oil spills and investigate dangerous environments. And now, scientists at the University of Manchester are using a robot as a laboratory partner.
The researchers at the university created the robot in 2009 and named it Adam. Despite the name, Adam is not a humanoid robot. It is about the size of a car.
Adam was built to do science and make discoveries. Ross King is the leader of the University of Manchester research team. He says the robot made a discovery about yeast(酵母), a kind of fungus(真菌) used in science as a model for human cells.
"Adam hypothesized certain functions of genes within yeast and experimentally tested these hypothesizes and confirmed them. So it both hypothesized and confirmed new scientific knowledge."
Adam's success as a scientist led to the creation of another robot scientist named Eve. Researchers developed Eve to design and test drugs for tropical and neglected diseases. These diseases kill and infect millions of people each year.
Drug development is slow and costly. Experts say it can take more than 10 years and about $1 billion to discover and develop new medicines. Drug manufacturers are unlikely to get their investment money back.
So the University of Manchester developed a low-cost test that shows whether or not a chemical is likely to be made into an effective medicine. Mr. King says that other drug testing methods were not very effective.
"How it works conventionally is you use robotics as well and you have a large collection of possible drugs. You test every single compound. And you start at the beginning of your library and continue until the end, and stop. So it's not a very intelligent process. The robotics doesn't learn anything as it goes along, even if it's tested a million compounds, it still doesn't have any expectation of what will happen next when it tests a new compound."
Mr. King says that Eve is different because the robot learns as it tests different compounds. He says the robot is designed to ignore compounds that it thinks unlikely to be good. It will only test the compounds which have a good chance of working.
Eve has discovered that a compound known to be effective against cancer might also be used to fight against malaria and other tropical diseases.
Mr. King says he hopes to completely automate the drug testing process with robots like Eve to create and test new chemicals. But he says humans remain in control of the manufacturing process.Scientists now are using a robot to__________.
| A．manufacture cars |
| B．work in the laboratory |

Autism spectrum disorder is a developmental disability. People with autism have trouble communicating and with social skills. The U.S. Centers for Disease Control and Prevention says the person also might repeat some behaviors and not want change in their daily activities. Some people with the condition need a lot of help. Others need less.
CDC officials say autism affects one in every 68 children in the United States. More boys than girls are believed to have the condition. But the number of cases appears to be growing. It is unclear whether the growing number shows a real increase or comes from more knowledge about this disorder.
Symptoms of autism
Common signs of autism include trouble making eye contact and a delay in learning how to speak. Some people with severe autism never learn how to talk. Many people with autism also have difficulty understanding facial expressions and the feelings of others. They also have trouble making friends of the same age.
Doctors have learned how to recognize autism, but much is still unknown about its causes.
Researchers at Harvard University have come closer to finding answers. They found that women exposed to the highest levels of fine particulate air pollution late in their pregnancies are two times more likely to give birth to a child with autism. The findings appeared in Environmental Health Perspectives -- a publication of the National Institute of Environmental Health Sciences.
The study found that the women who were around high levels of fine particulate matter air pollution were at highest risk of having an autistic child. The increased risk of these women was two times that of women who lived in areas with low levels of fine particulate pollution.
The researchers found that the timing of exposure to pollution was important. They found no increased risk of autism in children whose mothers were around high levels of pollution before becoming pregnant. And the study found air pollution does not seem to increase the risk of children developing autism after they are born.
What can pregnant women do?
Mr. Weisskopf says pregnant women should avoid air pollution as much as possible. But he warns that other things may increase the risk of autism spectrum disorder.
"You can avoid being in extremely polluted cities during pregnancy if possible. You can also choose to go running in a park rather than next to a street. But that said, I think also it's very important to recognize that autism spectrum disorders is a very multi-factorial disorder. And there are lots of reasons why risk could be increased."
Autism is believed to result from a combination of environmental and genetic factors.
For now, Marc Weisskopf says researchers are trying to identify the exact substances in air pollution that increase the risk of autism.What can we learn from Paragraph 1________?

Most children have heard their parents at one time or another yell "sit up straight!" or "don't slouch!"
In the past, this was usually heard at the dinner table as children ate dinner. But these days, it is also heard around another activity-video games.
Ten-year old Owaish Batliwala, from Mumbai, India, admits he spends three to four hours each day playing games on his tablet computer. His mother Mehzabin became concerned when her son started saying that his neck hurt.
She said, "My son started having neck problems around June or July. The pain slowly spread to his hand and his back. He plays for hours on the iPad and mobile phone. This is what has caused the problem."
Sadia Vanjara is a physical therapist. She says the number of young children with chronic pain in their necks, arms and shoulders is on the rise. Dr. Vanjara says the pain is not from aging, accidents or disease. It is from poor posture, or body position, while playing video games.
"They are not aging, they haven't had an accident, their age is like, under 10, they are not complaining, the blood reports are fine, their x-rays are fine, their MRI's are fine, then where is the culprit(罪魁祸首)? And that is the very common thing that is happening amongst all children and that is smart phones and the gadgets(小电器)."
This is a problem in many parts of the world. But there are more smartphone users in India than anywhere else in the world, except China. Networking equipment company Cisco estimates that the number of smartphone users in India will increase from 140 million today to 651 million by 2020.
19-year old student Nida Jameel says she feels pain in the finger which holds the weight of her smartphone most of the day.
She says she uses her smartphone 24/7. This means 24 hours a day, seven days a week, or all the time.
"As I use phone 24/7 (all day) like, so probably yeah, it was because of the phone, continuous usage and Snapchat, Whatsapp, more and more you know social media coming, so like phone is the center of everything."
Dr. Vanjara says the best treatments for the pain are daily exercises.
"And start stretching it in all the possible directions that you can."
Correct posture can help prevent pain. Dr. Vanjara teaches children how to hold their gadgets correctly. She tells a patient to hold the gadget in front of the face. She says that bending the head down to look at the device, strains the neck and creates an unhealthy bend to the back.
Sadia Vanjara predicts we will see not only physical but psychological and emotional problems resulting from overuse of gadgets.
Experts advise taking breaks from using a computer or other device often. Stand up. Stretch your legs, back, shoulders and arms. And when your work or school work is done, unplug and exercise.AccordingtoParagraph2,when will one hear yells like “sit up straight!”_________?

Celebrity TV presenter Ju Ping has been a host on China Central Television for 30 years, but her recent experience fronting a charity event was one of the most special moments in her career.
On April 2, World Autism Day, Ju partnered with Xia Junqi, a 17-year-old autistic teenager, to host a charity gala at the Beijing National Aquatics Center, otherwise known as the Water Cube.
The event was organized by One Foundation, which aims to increase public awareness of autistic people and their needs.
Autism is a neural disorder that impairs sufferers’ communication skills and social interactions. Sufferers have restricted, repetitive patterns of behavior. It affects about 1.6 million people in China, with medical studies suggesting autism may affect one in every 166 children.
Autism has no cure. For many years it went largely undiagnosed in China but early intervention and continuous education may help to teach the autistic self-help skills and lessen their disruptive behavior.
The gala featured autistic children singing, dancing and performing, and was greeted with enthusiastic applause from the audience.
Cai Chunzhu, a celebrity playwright, recalled feeling heartbroken when his son was diagnosed with autism at the age of 2. He says his family struggled to accept the reality but finally made peace with the diagnoses in the past four years. He says the boy lives in his own world and is trained in an intervention facility. Sun Zhongkai, executive director of the Beijing Stars and Rain Institute for Autism, one of the earliest intervention facilities for autistic children in China, shared with audience his deep sorrow for parents who often collapsed with desperation when he told them there was no cure for their autistic children.
Over the years, Chinese society has become more supportive of autistic people and their families, but there are still challenges in terms of getting autistic people employed and looking after them when their parents pass away.
Actor Zhou Xun also called on society to show greater understanding and support toward autistic children and their families.Where did the gala take place?
| A．In a theater in Shanghai. | B．In the Water Cube. |
| C．In a Children’s Palace. | D．In Nanjing. |
What does the underlined word “impairs” mean in the fourth paragraph?
| A．damages sth or makes sth worse. |
| B．improve sth or become sth better. |
| C．feel what they do the saddest. |
| D．increase the interest of knowing sth |
What can we know from the seventh paragraph?
| A．Some parents were in deep sorrow when they heard their children can be cured. |
| B．Cai Chunzhu is executive director of the Beijing Stars and Rain Institute for Autism. |
| C．Sun Zhongkai recalled feeling heartbroken when his son was diagnosed with autism at the age of 2. |
| D．Autism is a kind of disease that can not be cured. |
What is the attitude of our society and enthusiastic people?
| A．Some actors like Zhou Xun called on people to do nothing for autistic children. |
| B．Chinese society and people have become more supportive of autistic people and their families. |
| C．Some people want to give up helping autistic people because of many challenges they face. |
| D．Autistic children won’t be looked after when their parents pass away. |
Scientists are learning new things about Antarctica, the coldest place on Earth. For example, the Antarctic ice sheet is shrinking. A new study found that summer ice loss in parts of Antarctica was at its highest level in 1,000 years. The study showed that Antarctic ice was melting mostly from below ice shelves, where the water is warmer than the ice.
Eric Rignot is an earth system expert at the University of California, Irvine. He also works for the American space agency, NASA. There he serves as senior research scientist at NASA’s Jet Propulsion Laboratory, also in California. He says ice melting from below is responsible for 55 percent of the shelf loss from 2003 to 2008. That is a much higher rate than scientists thought earlier.
Professor Rignot and his team used satellite observations, radar and computer models to measure features above the ice to learn what was going on below.
The measurements show differences from one area to the next around the continent. The major ice shelves are called Ross, Filchner and Ronne. They make up two-thirds of Antarctica’s ice shelves. But they are responsible for only 15 percent of the melting ice.
The professor says even small changes, like changes in ocean flow driven by wind, can make a huge difference in the melting of the ice shelf.
Sixty percent of the Earth’s fresh water is held in the huge Antarctic ice sheet. Professor Rignot says the study will help experts predict how the continent reacts to warmer ocean waters and helps to cause rising sea levels around the world. The study was published in the journal Science.What’s the main idea of the passage?
| A．the Antarctic ice sheet is shrinking |
| B．the coldest place on earth |
| C．the major Antarctica’s ice shelves |
| D．the Atlantic Ocean are changing |
