No one is glad to hear that his body has to be cut open by a surgeon（外科医生）and part of it taken out．Today，however，we needn’t worry about feeling pain during the operation．The sick person falls into a kind of sleep，and when he awakes， the operation is finished．But these happy conditions are fairly new．
Long ago，operation usually had to be done while the sick man could feel everything．The sick man had to be held down on a table by force while the doctors did their best to save him．He could feel all the pain if his leg or arm was being cut off，and his fearful cries filled the room and the hearts of those who watched．
Soon after 1770，Josept Priestley discovered a gas which is now called “laughing gas”．Laughing gas became known in America．Young men and women went to parties to try it． Most of them spent their time laughing，but one man at a party，Horace Wells，noticed that people didn’t seem to feel pain when they were using this gas．He decided to make an experiment on himself．He asked a friend to help him．
Wells took some of the gas，and his friend pulled out one of Wells’ teeth．Wells felt no pain at all．
As he didn’t know enough about laughing gas，he gave a man less gas than he should have．The man cried out with pain when his tooth was being pulled out．
Wells tried again，but this time he gave too much of the gas，and the man died．Wells never forgot this terrible event．
24. Long ago，when the sick man was operated on, he _________．
A．could feel nothing B. could not want anything
C．could feel all the pain D．could do anything
25. Using the laughing gas, the people did not seem to _________．
A．be afraid of anything B．feel pain
C．want to go to the parties D．be ill
26. If a man took less laughing gas than he should have when an operation went on, he _________．
A．felt nothing B．felt very comfortable
C．still felt pain D．would die
27. One who took too much of the laughing gas _________．

C．would never feel pain D. would be very calm
Many countries have passed safety laws that require seat belts in vehicles. A modern three-point seat belt, also called a safety belt, is a harness to prevent the driver or a passenger from flying forward and hitting hard against the interior of a vehicle during a collision. A modern seat belt will help to position you properly to gain maximum benefit from your car’s airbags that will inflate（使充气）during a collision. Using a seat belt also prevents you from being ejected (弹出) from a car into the path of oncoming traffic. Research shows that when you wear a modern seat belt, you reduce the risk of death or serious injury by 70% or more during an auto accident.
Seat belts have existed in different forms since the early days of automobiles, and they have changed from a single lap belt to the three-point seat belt we use today. In 1911 the first airplane seat belt was installed. Then, in the 1920’s they were used in racecars. By the 1930s, a group of American physicians created lap belts for their own vehicles and urged vehicle manufacturers to provide seat belts on all vehicles.
Dr. C. Hunter Shelden made a major contribution to our safety with his article in the November 5, 1955 Journal of the American Medical Association (JAMA). He strongly encouraged the manufacture and use of door locks, airbags, and retractable(伸缩式的) seat belts, like the ones we use today. The modern three-point seat belt, including a lap belt and a shoulder belt, was introduced as standard equipment on Volvo cars in 1959.
In 1970, the state of Victoria in Australia made the wearing of a seat belt compulsory for every car driver and front-seat passenger. Today many countries have also mandated(授权) the use of five-point safety harnesses for carefully designed child safety seats that can protect a child during a serious car accident.
An airbag is a Supplemental Restraint System, or SRS, and consists of a rapidly inflatable restraint cushion that works together with a seat belt to protect you during a collision. Modern cars often contain several airbags in various locations. Since airbags can only inflate once and will quickly deflate after the initial impact, they will not provide any protection for you during a secondary collision.
The inflation of airbag can protect or hurt you. The risk zone for a driver’s airbag is the first 8 centimeters from its pre-inflation location. While driving, you should remain about 25 centimeters from the airbag in the center of the wheel. As a driver, wear your seat belt and make sure children correctly use their seat belts. Failure to wear a seat belt properly means the airbags in your car might injure or even kill you during an accident.
An essential part of your safe driving skills is the habit of making sure that you and each of your passengers are always properly positioned and wearing a seat belt. There are many wonderful benefits of being able to drive a car, but there are also severe consequences during an accident for anyone who chooses not to wear a seat belt.

With the average temperature for January standing at -50℃, it is no wonder the village is the coldest permanently inhabited settlement in the world. Known as the 'Pole of Cold', the coldest ever temperature recorded in Oymyakon was -71.2℃.
This is the lowest recorded temperature for any permanently inhabited location on Earth and the lowest temperature recorded in the Northern Hemisphere.
Ironically, Oymyakon actually means 'non-freezing water' due to a nearby hot spring. Most homes in Oymyakon still burn coal and wood for heat and enjoy few modern conveniences.
Nothing grows there so people eat reindeer meat and horse meat. A single shop provides the town's bare necessities and the locals work as reindeer-breeders, hunters and ice-fisherman.
Doctors say the reason the locals don't suffer from malnutrition is that their animals' milk contains a lot of micronutrients.
Unsurprisingly, locals are hardened to the weather and unlike in other countries— where a flurry of snow brings things grinding to a halt, Oymyakon's solitary school only shuts if temperatures fall below -52℃.
There are few modern conveniences in the village— with many buildings still having outdoor toilets - and most people still burn coal and wood for heat. When coal deliveries are irregular the power station starts burning wood. If the power ceases, the town shuts down in about five hours, and the pipes freeze and crack.
Daily problems that come with living in Oymyakon include pen ink freezing, glasses freezing to people's faces and batteries losing power. Locals are said to leave their cars running all day for fear of not being able to restart them.
Even if there was coverage for mobile phone reception the phones themselves would not work in such cold conditions.
Another problem caused by the frozen temperatures is burying dead bodies, which can take anything up to three days. The earth must first have melted sufficiently in order to dig it, so a bonfire is lit for a couple of hours. Hot coals are then pushed to the side and a hole couple of inches deep is dug. The process is repeated for several days until the hole is deep enough to bury the coffin.
Travel companies offer tourists the opportunity to visit the village and sample life in the freezing conditions.
Which of the following statements about this village is true?
| A．Local children don’t go to school because of the extreme cold. |

| A．before the first paragraph |
| B．after the first paragraph |
| C．after the sixth paragraph |
| D．before the last paragraph |

The insanely popular song ‘Gangnam Style’ from South Korean recording artist PSY has just become the most watched video on YouTube ever, garnering more than 808 million views on the popular media site.
The distinction was previously held by another pop heavyweight, Justin Bieber, whose song ‘Baby’ had a little more than 804 million views at press time. PSY made the announcement on his Twitter page earlier today.
Since its release, the song has defeated such other popular videos as Jennifer Lopez’s ‘On the Floor,’ Eminem's ‘Love the Way You Lie’ and LMFAO’s ‘Party Rock Anthem.’ And in September, 'Gangnam Style' also became the most liked video on YouTube, now with nearly 5.4 million thumbs up.
At the time of the announcement, the Guinness Book of World Records released a statement saying: “In years past it was unthinkable that something would be viewed a hundred million times, and now Gangnam Style has achieved more than twice this figure in just three months on YouTube. PSY, your certificate is waiting here at our office, come pick it up any time!”
Despite its massive popularity, the video shows no signs of slowing down, and it even has a shot at becoming the first video to get more than one billion views.
If it maintains its current rate of around six million new views per day, ‘Gangnam Style’ would be in line to break that record by the end of the year.
The YouTube honors are just the latest in a long list that shows just how popular the song has become. Since it was released in July, the song has seen a meteoric rise through the music industry.
It has found its way to the tops of music charts in more than 30 countries, including the United Kingdom, Germany, France, Spain and Canada, while providing material for thousands of parody（恶搞）videos.
It became a staple (主要部份) in the 2012 presidential elections with the now famous ‘Mitt Romney Style’ video and was even used by the North Korean government in propaganda films promoting their supreme leader.
Meanwhile, such influential figures as President Obama, UN Secretary General Ban Ki-moon and Google Executive Chairman Eric Schmidt have all made mention of the hit song.This passage mainly talks about a world famous________.

The age at which kids first fall victim to bullying (欺侮）could influence how strongly they are affected，suggests a new study. And，surprisingly，it is not the youngest kids who are hurt the most in the long term.
Bullying can have long-lasting effects，but particularly when it begins in adolescence，the researchers say. People subjected to either verbal ( 口头 上的）or physical bullying are known to be at greater risk of developing depression，anxiety disorders or to behave violently. But not everyone reacts in this way.
Children bullied for the first time before they hit adolescence seem to get over it， but those who are bullied for the first time later on in adolescence seem to become more aggressive or are more likely to turn to drink as a means of coping. These are the conclusions of psychologist Matthew Newman and colleagues from the University of Texas at Austin，US.
The team gave questionnaires to nearly 1，500 college students regarding their experience of physical and psychological bullying before adolescence—before high school—and in late adolescence—at high school. They assessed mood and mental state，judging by signs of anxiety or depression，such as sleeplessness. The group was also questioned about how they would react to certain challenges，such as humiliation.
People who were bullied all revealed slightly higher levels of stress. But while those bullied earlier in life seemed to respond normally to provocation (杉匕畔)，people bullied for the
first time late in adolescence are more withdrawn and sensitive to violence.
There are also sex differences between those bullied for the first time during adolescence， with females more likely to react aggressively when provoked and males are much more likely to turn to alcohol to escape bad situations.
The best solution in all cases was strong social support，whether from friends，family or school. Those with no one to share their problems with suffered the most.
So perhaps it is best not to shelter children completely from bullying early on，suggests Newman. “They may get stressed，but unhealthy coping really jumps out when they are bullied for the first time later on. ”

For many years，machines have been doing work that people once did，including some dit- ficutt jobs. Search and rescue operations in dangerous environments are often seen as the first areas that will employ high technology robots. But there is another area where they may soon take jobs traditionally held by human beings： the restaurant industry.
Teams from around the world competed in early June at the DARPA Robotic Challenge Finals in California. A team from South Korea and its robot，called DRC-Hubo，won the first place in the competition. The second and third place winners were from the United States. The robots were required to drive a vehicle，climb up steps and do mechanical work. Such activities are easy for humans to perform，but more difficult for machines. Not all of the competitor were successful. The failures showed how difficult it is to design effective walking
machines.
Akihiro Suzuki works at Yaskawa Electric，a company that develops robots. He says robots cannot do everything a human can，but they are able to work without becoming tired. He says robots cannot taste food，change heating levels or seasonings to get the best flavor (风味）.But he says if a food can be easily prepared，a robot can repeat the same movement to reproduce the same meal.
One Japanese woman who saw the robots working wanted to bring them home. Masayo Mori says she would like to have a husband who could work like a robot. Suzumo Machinery showed its sushi (寿司）maker robot. It performs the often difficult work of wrapping the popular Japanese food. Hiroshi Monden is an official with the company. He says people all over the world now eat sushi，but there are not enough skilled workers to prepare it. He says his machine can help anyone make sushi.
