Since the beginning of the year, smog has covered parts of North China. In January, Beijing saw only five days without smog. The rising PM 2.5 readings terrified many people, and some health experts said that whenever the smog gets serious, hospitals receive more patients suffering acute respiratory（呼吸系统）and heart diseases.
Later, news of polluted underground water in some provinces scared people who wondered whether the water they drink is safe.
So the need to emphasize environmental protection while developing the economy is heard everywhere.
Smog especially is a common concern. Like a popular online post said, air may be the only thing that is equal for everyone, despite your income or vocation. People with higher incomes are able to drink only bottled spring water and eat only organic food by paying higher prices, but they breathe the same air as everyone else.
At a meeting on Monday, many Representatives have expressed their concerns about the air quality, too. One talked about his experience in Beijing. “After taking a taxi from the capital airport to my hotel, which took about an hour, I washed my nose and found the inside of my nose was black. We should ask ourselves this question: Why do we want to develop? It's for living a better life. Dirty air is definitely not a better life," he said.
China needs to develop its economy and invest(投资) in high-tech. Every Chinese wants a strong country. But without blue sky, clean water and safe food, the achievements in the economy will become meaningless. Space technologies are not to be developed for building a base on Mars so that one day all human beings can migrate to the red planet because they have destroyed Earth.
What the public wants is a strong and beautiful China. Former president Hu Jintao spoke at the 18th Party Congress last November saying that great efforts must be made to promote ecological progress and build a beautiful China. The words have shown the central government's resolution to address the environment issue. The effect of smog doesn’t include.

Why smog has become a common concern?
| A．Because people have to pay higher prices. |
| B．Because nobody can avoid it. |

"Our aim is to take our art to the world and make people understand what it is to move," said David Belle, the founder of parkour (跑酷).
Do you love running? It is a good exercise, yet many people find it boring. But what if making your morning jog a creative one? Like jumping from walls and over gaps, and ground rolls? Just like the James Bond in the movie Casino Royale, Bond jumps down from a roof to a windowsill and then runs several blocks over obstacles on the way. It is just because of Bond's wonderful performances that the sport has become popular worldwide.
Yes, that's parkour, an extreme street sport aimed at moving from one point to another as quickly as possible, getting over all the obstacles in the path using only the abilities of the human body. Parkour isconsidered an extreme sport. As its participants dash around a city, they may jump over fences, run up walls and even move from rooftop to rooftop.
Parkour can be just as exciting and charming as it sounds, but its participants see parkour much more than that.
Overcoming all the obstacles on the course and in life is part of the philosophy (理念) behind parkour. This is the same as life. You must determine your destination, go straight, jump over all the barriers as if in parkour and never fall back from them in your life, to reach the destination successfully. A parkour lover said, "I love parkour because its philosophy has become my life, my way to do everything."
Another philosophy we've learnt from parkour is freedom. It can be done by anyone, at any time, anywhere in the world. It is a kind of expression of trust in yourself that you earn energy and confidence.Parkour has become popular throughout the world because of __________.
| A．its founder, David Belle |

STRANGERS parties go wild these days. The main idea of them is to never let the people know who their matches are until the last minute. These are some popular practices that are storming the world’s youth on this V-day.
Speed dating
It's exactly what the name implies. Complete with a timer, a whistle and 50 willing singles, speed dating is not the traditional dinner and a movie type of first date. Singles pay US MYM35 for three minutes with more than two dozen future dates. They ask questions and try to get to know each other. At the sound of a whistle, they do the same thing all over again—25 times in all.
Lock and key party
Women are given a lock and men are given a key, upon arriving at the party. Each key and lock has several matches. One can hunt for his/her laterto-be sweetheart in various groups, and try out the key or lock. Each time a lock and key matching the pair are entered into a ballot (票数) for top prizes!
Dinner in the dark
Waiters wearing night vision glasses guide the guests through the pitch-black dining room. They are seated at the table and familiarized with the wine glass and plate. Food is handled with the fingers. People will not see the food they are eating or the guests at their table until the dessert course. At that moment, dining partners will appear.
Message party
Have A Cocktail, Leave A Message! When you arrive, you get a tag with a number and a pad of post it notes. If you see someone you like, write a message on the message board. But wait... You've got a message... Go and collect it! You can make newfriends and win lots of gifts.

Robots have proved to be valuable tools for soldiers, surgeons and homeowners hoping to keep the carpet clean. But in each case, they are designed and built specifically for the job. Now there is a movement under way to build multipurpose machines—robots that can move about in changing environmentssuch as offices or living rooms and work with their hands.
All-purpose robots are not, of course, a new idea. "It's been five or 10 years from happening for about 50 years, " says Eric Berger, co-director of the Personal Robotics Program at Willow Garage, a Silicon Valley organization. The delay is in part because even simple tasks require a huge set of capabilities. For a robot to fetch a mug, for example, it needs to make sense of data gathered by a variety of sensorslaser scanners identifying potential blocking objects, cameras searching for the target, force feedback in the fingers that grasp the mug, and more. Yet Berger and other experts are confident that real progress could be made in the next decade.
The problem, according to Willow Garage, is the lack of a common platform for all that computational effort. Instead of enlarging the capabilities of a single machine, everyone is designing robots and the software to control them, from the ground up. To help change this, Willow Garage is currently producing 25 copies of its model PR2 (for "Personal Robot 2"), a two-armed, wheeled machine that can switch off the electricity, open doors and move through a room. Ten of the robots will stay in house, but 10 more will go to outside research groups, and everyone will share their advances. This way, Berger says, if you want to build the robotic equivalent (等同物) of a Twitter (推特网站), you won't start by constructing a computer. "You build the thing that's new."The robots are mentioned to do some specific jobs EXCEPT in __________.
| A．battle fields |
| B．operation room |
| C．people's houses |
| D．wild fields |
The multipurpose robot may be identified as a machine that __________.
| A．can move about in changing environments and work with their hands |
| B．can make sense of data gathered by a variety of sensors |
| C．has a huge set of abilities to finish all the simple tasks |
| D．has identifying laser scanners, searching cameras and force feedback |
According to Willow Garage, we will make realprogress in building all-purpose robots if __________.
| A．everyone is designing robots and the software to control them |
| B．they can produce 25 copies of its model PR2 |
| C．people can enlarge the capabilities of a single machine |
| D．people can start by constructing a computer |
Ed Viesturs grew up in Rockford, Illinois, where the tallest thing on the horizon was the water tower. But on Thursday, Viesturs became the only American to climb to the top of the world's 14 highest mountains.
His last hike was up Mount Annapurna, in Asia's snowcapped Himalayas. At 26, 545 feet, its peak is the 10th highest in the world. It is the mountain that inspired him to start climbing.
"It tends to be the trickiest, the most dangerous, said Viesturs."There's no simple way to climb it. There are threatening avalanches (雪崩) and ice falls that protect the mountain."
In high school, Viesturs read French climber Maurice Herzog's tale of climbing the icy Annapurna. Herzog's story was of frostbite (冻伤) and difficulty and near-death experiences. Viesturs was hooked right away.
Viesturs got his start on Washington's Mount Rainier in 1977, guiding hikes in the summer. Fifteen years ago, he set out to walk up to the world's highest peaks. Finally, he's done.
The pioneering climber talks about mountains as if they were living creatures that should be treated with respect. "You have to use all of your senses, all of your abilities to see if the mountain will let you climb it," said Viesturs. "If we have the patience and the respect, and if we're here at the right time, under the right circumstances, they allow us to go up, and allow us to come down."
What's next for a man who can't stop climbing? "I'm going to hug my wife and kids and kind of kick back and enjoy the summer," says Viesturs. But for a man who's climbed the world's 14 tallest mountains, he will probably soon set off on yet another adventure.What record has Ed Viesturs set?
| A．He has succeeded in climbing to the world's 14th highest mountain. |
| B．He has been to the top of the world's 14 highest mountains. |
| C．He has become the first to climb to the height of 26, 545 feet. |
| D．He has become the first man to climb to the top of 14th highest mountains in the world. |
The underlined word "hooked" in Paragraph 4 can be replaced by "__________".
| A．frightened |
| B．discouraged |
| C．interested |
| D．upset |
The author used Viestures' words in Paragraph 6 to support a view that __________.
| A．mountain climbing is a dangerous sport |
| B．mountains should be regarded as living creatures |
| C．mountain climbing needs more skills than physical energy |
| D．those who like mountain climbing won't stop climbing |
What's the next probable plan of Viestures?
| A．Stopping climbing and staying with his family. |
| B．Climbing to the top of the world's 14 tallest mountains again. |
| C．Climbing another one of the highest mountains. |
| D．Writing down the experiences about his adventure. |
