[EX Q]: Article: Today, Mount Qomolangma's peak is not a lonely place any more. More than 3,500 people have successfully climbed the 8,844m mountain, and more than a tenth of that number reached the peak just over the past year. As more and more people try to test themselves against Qomolangma, many a time the mount can be very crowded. Climbers have complained about waiting for hours in the bottlenecks on the way to the peak. If bad weather strikes, climbers can and do die. But the dangerous crowds aren't the only problem on Qomolangma. All those climbers need to bring a lot of _ --much of them ends up being left on the mountain, sometimes even the peak itself. Mount Qomolangma is becoming the world's tallest rubbish dump. Here's mountaineer Mark Jenkins writing in National Geographic about the state of Qomolangma: "The two standard routes, the Northeast Ridge and the Southeast Ridge, are not only dangerously crowded but also badly polluted." But the good news is that some mountaineers are taking it upon themselves to clean up Qomolangma. Mountaineer Paul Thelen and his friend Eberhard Schaaf are part of the annual Eco Everest Expedition, which has been cleaning up rubbish from base camps to the peak since 2008. So far they've collected over 13 tons of garbage. Some of that rubbish is even being used for a higher purpose. As part of the Mount Everest 8844 Art Project, a group of 15 artists from Nepal collected 1.5 tons of garbage brought down the mountain by climbers. They've changed the cans and oxygen tanks--in one case, part of the remains of a helicopter--into 74 pieces of art that have already gone on exhibition in Nepal's capital. Part of the profit from sales will go to the Everest Peakeers Association, which has helped collect tons of rubbish off the mountain.
Question: What do we learn about the bottlenecks on the way to Mount Qomolangma's peak?
Options: (A) They are relatively safe. (B) They are often crowded. (C) They are very easy to pass. (D) They are sites of base camps.
Asnwer: C
[EX A]: No

[EX Q]: Article: Almost 70 percent of Chinese middle school students have serious problems with their parents, the Beijing Morning Post quoted a survey as saying. The survey showed 6.62 percent of the surveyed students are afraid of their parents while 13.13 percent of them dislike their parents and 56.28 percent were extremely disgusted with or even hate their parents. Only 4.75 percent of the young people surveyed said they like their parents. The recently conducted survey among 3,000 middle school students in a Beijing district asked questions about their attitude toward their parents and family education, the paper said. For many families, conflict between parents and children center on the student's school grades, their weight and their friends. The survey showed that parental influence over children is decreasing, the paper said. Xiao Xiao, a third year junior middle school student is perhaps typical of most kids when she complains; "I was scolded by my mother because I didn't come first in the class in a mid-term exam." Xiao Xiao in fact is already one of the top students in her class, the paper said, stressing Xiao Xiao's parents hope she can study at the Beijing University or even attend Harvard in the future. Sun Yunxiao, an expert with the China Youth and Children Research Center, said "parents expect unrealistically high expectations from their children." The research centre's own survey of parents showed about 55 percent of parents hope their children will study for a doctoral degree and 83.6 percent require their children to rank in the top 15 of their class. Conflicts between parents and their children not only come from too high education expectations. Other causes of disconnection between parents and children are family violence, parents' old fashioned ideas, interference in a child's privacy including their choice of friends and time spent surfing the web, the paper said. Mr Hu, a father of a middle school student, wasn't surprised by the survey results. He says too much concern over school marks is putting tremendous pressure on families.
Question: How many young people surveyed said they like their parents?
Options: (A) 39390. (B) 19860. (C) 14250 (D) 168840
Asnwer: A
[EX A]: No

[EX Q]: Article: A Scottish woman has given birth to twins for the third time. Karen Rodger, 41, welcomed her first pair of girls rowan and Isla after having twice given birth to twin boys. "I still haven't really taken it on board because I was convinced I was having two boys," Rodger told Sky News. Karen said her husband Colin was equally stunned when the couple learned they were going to have their fifth and sixth child. "He thought I was joking and immediately wrote back to say 'this is not funny'. I had to explain that it really was true," Karen said. The average couple has about a 3 percent chance of having twins when not accounting for fertility drugs. And with each following pregnancy, the changes of producing twins a second, or even third time, become less. Karen, a dance lecturer, first learned of the incredibly rare occurrence during a visit to her doctor and immediately texted her husband to share the news. "I just could not believe it. It never crossed my mind that it would be twins again. I just thought that wouldn't happen to people like me, but I'm ly delighted," she said. It had been several years since the couple's last children were born. Their oldest twins are 14 and the second set was born just two years later. "I turned 40 and I thought, if I'm going to do it, I should do it now," Karen said. "I spoken to my husband and we both thought we'd quite like another one so that was it and, one month later, I was pregnant." Colin says the age and gender difference will ensure a sweat-inducing dilemma for any future suitors of the twin girls. It will be a frightening challenge for any boyfriend.
