There's been a thought that younger consumers have been the driving force of online buying. That may not be the case. According to a statement from Alipay, the average expenditure of Alipay users born before the 1960s was 31,000 yuan in 2012, much higher than 14,000 yuan of those born after the 1980s. It shows that online shopping has become a key part of people's daily consumption, for both young and old. Besides shopping, people pay bills such as water bill, electricity bill, and credit card repayment online. The middle-aged and senior consumers are also participating in that consumption revolution. Liu Chen, 56, said that his online expenditure in 2014 was over 50,000 yuan, about half of the total annual expenditure. He always pays his telephone bill online. Clothes, electrical appliances and kids' snacks are the main items he purchases online. Liu's shopping strategy is to find something good online first, then go to shops to check it out, and finally buy it online because it is cheaper. As quality concerns him, Liu only buys items that come with a guarantee. Stories such as those from Liu are representative of millions of middle-aged and older Chinese, which show the great potential of the aged in the Chinese consumption market. Yet, the market seems not to be valued as it should be. Some Chinese e-commerce websites such as jd. com, dangdang. com and amazon. cn don't have a category for goods for the elderly on their main pages. Alibaba's platform does have one, but the goods in it are not as abundant as other categories. Moreover, Taobao's category is not really designed for elders, but their children. Despite the seeming lack of commitment to older consumers, the Chinese market for the elderly is clearly huge, and e-commerce websites should take great efforts to develop it. Question: Liu Chen chooses online shopping mainly because of its _ . Options: A: low price B: convenience C: great potential D: quality guarantee

The only survivors over the next few months were the two pups Duncan had claimed, naming them 'Rin Tin Tin' and 'Nannette' after tiny French puppets the French children would give to the American soldiers for good luck. When the war ended, Duncan made special arrangements to take his pups back to his home in Los Angeles, but during the Atlantic crossing, Nannette became ill and died, shortly after arriving inAmerica. In 1922, Duncan and Rin Tin Tin attended an LA dog show, his dog performing for the crowd with an impressive high jump. After the show,Duncanreceived $350 for Rin's performance. That was the beginning of Rin Tin Tin's later involvement in many films and television series It happened that Warners had difficulty shooting an exterior scene with a wolf as they got into a low budget. Duncanquickly approached the director and told them that his dog could do the scene in one take. True to his word, Rin did the scene in one take. As a result, he and his dog were hired for the entire shoot of "Man From Hells River". The film was a hit and Rin Tin Tin became a box-office star. It was the first American dog movie star. It made 26 pictures for Warners while starring in his own live 1930s radio show "The Wonder Dog". At the peak of his popularity, Warners kept 18 trained stand-ins to reduce any stress on their dog star. The star dog was worthy of the honor of having its private _ to prepare daily lunches for him. As a band was playing classical music it slowly consumed a lunch of tenderloin steak. Question: Which of the following can replace "chef"? Options: A: musician B: cook C: consumer D: star

Read the article and select the best answer. Article: Walking home from work with a family friend, I found myself in a discussion about her daughter's going to college. It started with the mother telling me that she had no money to help her daughter go through college, which led the mother to push community college fiercely. She then started to say how she had been pushing "high-paying" fields on her daughter--doctor, engineer, lawyer, etc. When I asked her if that was what her daughter had interest in, she said no. I asked her what the point was to push her daughter into something that she didn't like, and she responded with, "I just want her to make a good fortune." After hearing her words, I would like to state that money is not everything. A high-paying job means nothing if you are miserable. I used to do a high-paid job, but it was very tiring and I had no time of my own. I didn't like it at all. Though the pay was good, I was not happy. So I'd like to tell parents, please do not force your children into a major or a career just because you think they are going to make a lot of money. They would feel terrible for taking that major or job just to comfort you. The worst part is the feeling of guilty when they decide to change that major to something they actually want or when they quit that job. Being a member of a generation who are willing to give ly everything to our kids, we know we just hope our children could live happy lives. Please do not force a career path on our children just because we think it is good for them. Give our children advice, but don't force them. Question: From the text, we can infer that the writer would most probably advise parents to _ . Options: A: choose the best major or career for their children B: avoid giving their children advice on their major or career C: let their children make the final decision on their major or career D: give everything to their kids to make sure they'll have a good future

Article: New experiments discover rats showing sympathy and helping other rodents .It is a characteristic some scientists thought was reserved only for humans and higher animals. In repeated tests, rats freed another trapped rat in their cage, even when yummy chocolate served as an attraction.24 of the 30 rats opened the trap by pushing in a door.The rats could have eaten the chocolate before freeing their partners, but often didn't, choosing to help and share the goodies. "Basically they told us freeing another rat is as important as eating chocolate," said study author Peggy Mason of the University of Chicago."That's a very striking thing." In some cases, the rats first took the chocolate chips out of a container, but didn't eat them, then freed the other rat and shared "almost as if they were serving them chocolate," Mason said.The research is reported in Thursday's journal Science. Also, females showed more consistent care and help than males, Mason said.All six females freed their trapped partner while three quarters of the 24 males did so.This confirms other studies that show females showing more pro-social behavior than males.There were time when the male rats took the day off from helping their trapped partner, but the females never did, she said. Jeff Mogil at McGill University in Canada, who wasn't part of the study, said it was a little surprising but even more convincing. Both scientists said social understanding is probably a characteristic that is important in the evolution of animals. Mason joked that if rats can be so caring and helpful, "there's a sense of optimism.It's something we could be." Question: What's the difference between the behavior of male and female rats? Options: A: Female rats showed more concern about their trapped partners. B: Male rats cared more about their trapped partners than females. C: Female rats behaved less pro-socially than male rats on the whole. D: Male rats didn't go away from their trapped partners for even a day.
