During the mid-1960s, VinhLinh, Quang Tri inVietnam was a wasteland, which was often underattack from the US air force. Vietnamese soldierswho were fighting against the US discussed how to
make people there safe. Some suggested moving thepeople underground. Then they began to build a tunnel(隧道)
The VinhMoc tunnel was built for the people ofSon Trung and Son Ha in VinhLinh county of QuangTri Province. It included wells, kitchens, rooms foreach family and hospitals. Around 60 families lived inthe tunnel.
Deep under the ground, hidden from soldiers,people lived in the tunnel for many years. Theysurvived. The tunnel was a success and no villagerslost their lives thanks to it.
During that time, 17 children were born in thetunnel, each of whose lives was a proof that thetunnel was effective in protecting the villagers. Astime goes by,it has become both a historical site anda tourist attraction for people wishing to learn abouta heroic period in Vietnam's history.
The total length of the tunnel network is nearly 2km, and has three floors. It was built over twoyears. The two sides have small houses every 3m. Thetunnel centre has a 150 - seat hall, a hospital and
maternity rooms (产房). It is linked to the sea byseven exits, which also function as ventilators(通风设备), and to a nearby hill by another six.
People wanting to know about the Vietnam Warshould have some knowledge of the tunnel network inQuang Tri. The tunnel network shows the wisdom andbravery of the local people in their fight for their
identity.
Ten years after the war ended, the VinhMoctunnel was opened to tourists. These days, thegovernment is working to protect the historical relic.Which of the following statements is NOT trueaccording to the passage?

Shree Bose is one of the most impressive kids graduating from Fort Worth Country Day High School this year. Bose has a large circle of friends, and there’s one who you may have heard of: President Obama. He has twice publicly recognized her achievements in cancer research and spoken with her in the Oval Office.
If that isn’t enough, Bose recently gave a TED Talk about her work with the cancer drug Cisplatin, which also won her first prize at the Google Science Fair and recognition as one of Glamour magazine’s Young Amazing Women of the Year.
After watching her grandfather struggle with liver cancer, Bose was determined to help out in any way she could. As a high school student，though, her scientific choices were limited. She reached out to various hospitals and research centers, but doctors turned down her requests because they felt she was too inexperienced medically.
Only the North Texas Science Health Center respected her determination and chose to guide her. The results were amazing.
Bose chose to study a protein and its reaction with the cancer drug Cisplatin. She noticed that when she prevented this protein from growing, Cisplatin was allowed to begin destroying cancer cells once again.
“My project not only contributes to the understanding of the relationship between the protein and Cisplatin, but also suggests a newer, more effective treatment for patients who resist Cisplatin,” Bose said.
Bose’s achievements aren’t limited to the lab, though. She was also captain of her swim team and editor-in-chief of her school paper.
Bose is currently getting practical experience at the National Institute of Health and she’ll be attending Harvard in the fall. She plans to study molecular biology and go to medical school. Eventually, she would like to be a doctor.President Obama has spoken with Bose because she ______.

Here's a hotel worth writing something about: a company in Poland plans to build tourist accommodation under the sea. The structure can be dragged to a suitable location and placed on supports on the sea bed. The ‘Water Discus’ will be made up of an underwater disc containing 22 bedrooms with sea views, connected by lift and stairs to a disc above the surface containing other hotel facilities.
Project manager Robert Bursiewicz says: “Nowadays it's possible to build submarines ('潜艇) which go deeper than 500m below the sea surface, so building an underwater hotel is not a problem. ”
In fact, they don't plan to have the hotel very deep. Water acts like a filter (过滤器) for sunlight, and below 15m most colors, apart from blue, are washed out. And we all want to see colorful marine life, don't we?
But this isn't the first hotel to offer underwater views from the bedrooms. The two-bedroom Jules' Undersea Lodge, off the coast of Florida, has been taking in guests 10m beneath the surface since 1986.
The company that operates the hotel also runs a diving course for beginners to help get guests down and into the hotel. It is accessible only through an opening at the bottom.
And you'll find all the usual facilities in the room, according to Teresa McKirma, Jules's chief financial officer. It has a television, air conditioning and Wi-Fi. But for the staff, simple things like cleaning and making beds can be challenging, since the lodge is in sea water.
"It actually takes quite a lot of work to get anything down there," she says. "We have to put everything in waterproof boxes and attach weights to them to counter their buoyancy (浮力). "
The hotel has suitably sized waterproof boxes so that pizzas can be delivered by divers to guests who order them for their evening meal. And after a meal, if you can't sleep because of the excitement of the experience, you don't have to count sheep. You'll fall asleep quicker if you count fish.According to the passage, the new hotel will ______.
| A．contain three discs | B．come into use soon |
| C．have a movable structure | D．be built 500m beneath the surface |
Why won't they plan to have the hotel very deep in the water?
| A．They have financial problems. |
| B．They lack advanced technology. |
| C．They refuse to enjoy colorful life. |
| D．Most colors are washed out below 15m. |
According to Teresa McKirma, ______.
| A．entertainment is impossible in the hotel |
| B．the staff's work is difficult to finish |
| C．it's easy to get things down there |
| D．the built hotel is badly equipped |
What can be inferred from the last paragraph?
| A．Passengers can't enjoy their meals. |
| B．Passengers will feel fed up with the views. |
| C．Passengers have no choice but to count fish. |
| D．Passengers may get excited about the experience. |
The Rugby (英式橄榄球) World Cup is currently being held in New Zealand. The tournament, due to finish on October 23, is living up to the famous English saying, “Rugby is a thug's (暴徒) game played by gentlemen. ”
The games are physically aggressive; the tackles (冲撞) on the pitch are brutal; but the end of each match is a civilized affair. Players shake hands and applaud each other. Of course, the other side to this saying is: "Football is a gentleman's game played by thugs. " Indeed, unlike soccer players, rugby players don't often question the referee's (裁判员) decisions or pretend to be injured when they are not.
“Football could learn a lot from rugby," said Brian Moore, a former England rugby player "The wonderful spirit of rugby is: there is a gentlemanly code to it. You play hard on the pitch, but you always respect your opponent..
Rugby is mainly played in Europe. Australia, New Zealand and parts of Africa. "It is more enjoyable to play than soccer because you are always involved in the game," said Peter, a Welsh rugby coach. "Rugby is also a far superior test of strength, stamina (耐力) and determination. "
Most professional rugby players are large, strong and weigh over 90 kilograms. People who play the sport need to be tough and be prepared to get hurt. Black eyes, broken bones, lost teeth and being knocked unconscious—all these are common injuries. Former British Prime Minister Gordon Brown is blind in one eye thanks to a rugby accident at school.
In England, children begin playing the game at school at the age of 8. When they enter high school, many begin to play full contact rugby. Children are taught to play for around one hour a week during their PE lessons. Most schools have a rugby team. Children who play for the school team are usually the sportiest kids, and are seen as brave and athletic. What can be concluded from the first three paragraphs?
| A．Football players are not real gentlemen. |
| B．There is a better spirit in playing rugby than football. |
| C．Football players are not as athletic as rugby players. |
| D．Brian Moore thinks that rules should be stricter in football. |
According to the passage, Peter thinks ______.
| A．rugby players pretend to be injured when they are not |
| B．rugby is not very popular in America and Asia |
| C．rugby makes people enjoy sports better than soccer |
| D．rugby needs players' strong will rather than strength |
The example of Gordon Brown is mentioned in order to .
| A．prove that playing rugby can earn people fame |
| B．explain why Gordon Brown is blind in one eye |
| C．support the point that rugby players often get hurt |
| D．warn teenagers against playing rugby at school |
What can we infer from the passage?
| A．Teenagers will lose interest in football. |
| B．English children have a talent for rugby. |
| C．Playing rugby doesn't involve skills. |
| D．Rugby is not suitable for everyone. |

If you saw another kid ride her bike too fast around a corner and fall down, you might ride your bike more slowly on that turn. Yes, we humans are very sensitive to others' mistakes. And the same is true for other animals. Animals mess up all the time. They might eat poisonous leaves, fall off a tree or let their prey (猎物) slip away. By watching others fail, an animal can avoid making the same mistakes, thus improving its chance of survival.
Scientists suspected that one part of the brain helps animals process information about others' errors. Cells in that part appear to become more active when a person sees someone else making a mistake. But researchers didn't know whether individual cells in this part of the brain play different roles in detecting errors.
To investigate the brain's response to errors in more detail, the researchers taught a game to two macaques, a type of monkey. One monkey could press a yellow or green button while the other watched. If the first monkey pressed the right button, the team gave both animals a treat. Every couple of rounds, the two monkeys switched roles. Meanwhile, the scientists monitored individual cells in the animal's brains.
When the first monkey messed up the game by pressing the wrong button, a group of cells in the second monkey's brain fired. But if the second monkey also made the wrong choice during its turn, some of the cells in that group didn't respond. Those unresponsive cells reacted specifically to mistakes made by others, not to the monkey's own mistakes.
Scientists believe other parts of the brain also might help people process information about another's errors. "You start to think about this other person and see things from his angle. " Ellen de Bruijn, told Science News. She studies the brain at the University of Leiden in the Netherlands. According to Paragraph 1 , animals' ability to learn from others' mistakes ______.
| A．used to be ignored by humans |
| B．ensures that they will never fail |
| C．is being lost because of humans |
| D．helps them to survive better |
The underlined word "detecting" in Paragraph 2 probably means "______".
| A．correcting | B．making |
| C．sensing | D．drawing |
In the experiment mentioned, those unresponsive cells are only sensitive to ______.
| A．the same buttons | B．others' mistakes |
| C．one's own mistakes | D．the monkey's brain |
