He met her at a party. She was outstanding; many guys were after her, but nobody paid any attention to him. After the party, he invited her for coffee. She was surprised, so as not to appear rude, she went along. As they sat in a nice coffee shop, he was too nervous to say anything and she felt uncomfortable. Suddenly, he asked the waiter, "Could you please give me some salt? I'd like to put it in my coffee." They stared at him. He turned red, but when the salt came, he put it in his coffee and drank. Curious, she asked, "Why salt with coffee?" He explained, "When I was a little boy, I lived near the sea. I liked playing on the sea. I could feel it salty, like salty coffee. Now every time I drink it, I think of my childhood and my hometown. I miss it and my parents, who are still there." She was deeply moved. A man who can admit that he's homesick must love his home and care about his family. He must be responsible. She talked too, about her faraway hometown, her childhood, her family. That was the start to their love story. They continued to date. She found that he met all her requirements. He was tolerant, kind, warm and careful. And to think she would have missed the catch if not for the salty coffee! So they married and lived happily together. And every time she made coffee for him, she put in some salt, the way he liked it. After 40 years, he passed away and left her a letter which said: My dearest, please forgive my life-long lie. Remember the first time we dated? I was so nervous that I asked for salt instead of sugar. It was hard for me to ask for a change, so I just went ahead. I never thought that we would hit it off. Many times, I tried to tell you the truth, but I was afraid that it would ruin everything.Sweetheart, I don't exactly like salty coffee. But as it mattered so much to you, I've learnt to enjoy it. Having you with me was my greatest happiness. If I could live a second time, I hope we can be together again, even if it means that I have to drink salty coffee for the rest of my life. She accepted his invitation for coffee because _ . A) she fell in love with him B) she didn't want to be impolite C) no one paid attention to him D) no one else was interested in her

Women work harder than men at university and get better degrees as a result, according to a study at Brunel University. The research, which followed 200 students for four years, found that women consistently outperformed men in their studies even though they had started their courses with almost identical A-level grades. An analysis of the results showed that while 65 percent of female graduates were awarded, only 35 percent of male graduates did as well. Girls are known to outperform boys at school, but this research showed that trend continued at university. Fiona Smith, who led the research, said, "The research shows that the difference has something to do with schools in general." "It also shows something about the inequality for working women in terms of pay and promotion. Women work harder at school, harder at university, and do better at both, but they still receive less pay." The research found that female students were more faithful, less likely to miss lectures, and more likely to believe that their marks reflected their abilities than male students. Female students were also more likely to ask for and receive support from their professors. Women were also more likely to choose their universities because they liked the courses offered. In contrast, men were more likely than women to miss lectures due to "other affairs" and "laziness", and to believe that playing sports was an important part of university life. Generally, people think that women's success comes from more emphasis on coursework, but the research showed that female geographers at Brunel did better in their exams than in their coursework. Dr Smith said, "Most women feel that getting good grades is the most important part of university life. They believe that they need to work harder in order to compete in the male-dominated environment they will encounter at work. Good grades are viewed as an 'insurance policy' for success. Men, on the other hand, prefer going out and playing sports to academic work." "This research shows how... We can infer from the results of the research that _ . A) women do better both at school and at university B) female students are more likely to ask for and receive support from their professors C) compared with men, women are in an unfavorable condition in the male-dominated world D) it's easier for women to get rises in pay and promotion

Ques:Does it drive you crazy that your cell phone needs to be frequently charged for hours? A team of scientists led by professor Harold Kung at Northwestern University in the US may have solved your problem. They developed a lithium ion batery that holds 10 times as much power and charges 10 times more quickly than standard batteries, according to the BBC in a report on November 15. Lithium ion bateries are rechargeable and are widely used in cameras, smartphones and laptops. They charge through a chemical reaction in which lithium ions are sent between the two ends of a battery. How much power the battery holds and how fast it charges are limited by two things:how many lithium ions it has and how quickly these ions move. Current rechargeable batteries have an anode made of many carbon-based graphene sheets. To increase energy capacity, former experiments have tried to replace the carbon with silicon, which can hold far more lithium ions. However, this method did not work because the silicon was not stable enough. Kung's team managed to stabilize the silicon. They put clusters of silicon between the graphene sheets like a sandwich so that the silicon could not move around freely and take away the energy. The speed at which a battery charges is hindered by the shape of the graphene sheets because it takes a long time for the lithium to travel from one side of the sheet to the other.Sometimes a "traffic jam" occurs around the edges of the graphene. To solve this problem, Kung's team used a special chemical process to create tiny holes of 10 to 20 nanometers wide in the graphene sheets so the lithium ions would have a "shortcut" and be able to travel directly to the other side. This reduced the time it took the battery to recharge. About 15 minutes of charging can last more than a week. "Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium ion batteries on the market today," said Kung. The technology could be widely available... We can infer from the article that _ . A) current rechargeable batteries usually last for 150 charges B) after one year's use, the newly developed batteries are less powerful C) batteries with more lithium ions are more powerful and charge faster D) further experiments may focus on improving the shape of graphene sheets
