He met her at a party. She was outstanding while he was so normal. After the party, he invited her for coffee. She was surprised but being polite, she agreed. 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. " Everyone 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 the taste of sea, just like this salty coffee. " That was a really nice talk, also a good beginning of their story. They continued to date. She found that actually he was a man who met all her demands. Then the story was just like every beautiful love story: they got married and lived a happy life. 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 could be the start of our conversation. I tried to tell you the truth, but I was afraid that it would ruin everything. I don't like the salty coffee. But I have had the salty coffee for my whole life just because I love you! Her tears made the letter totally wet. Someday, someone asked her, "What's the taste of salty coffee?" She replied, "It's sweet." She accepted his invitation after the party because _ .

Q: Have you ever dreamed about a trip to the space? Seeds of some vegetables and crops are a lot luckier than you, as they have travelled to space and back. China is among the three countries in the world that carry out agricultural research in space. The others are Russia and the US. Since 1987, China has sent about 1,000 species of seeds into space. These include green peppers, tomatoes, cucumbers , carrots, lettuce and wheat. Even on China's first manned spacecraft Shenzhou-V, there were some seeds from Taiwan. "Conditions in outer space such as radiation and low gravity can cause big changes in the seeds," said Chinese researcher Jin Xing. But not all seeds are better after going to space. After returning to Earth, the best seeds are selected.These seeds produce much more and also grow faster than normal seeds. As the safety of genetically modified food is still being debated, some people doubt the safety of these "space vegetables" because some of their genes are changed during the trip to space. But Jin holds a more positive view. He said, "unlike genetically modified crops, no new genes are introduced to the space vegetables, so they are definitely safe." China has also been co-operating with NASA to grow some super size potatoes on the International Space Station. Special growth rooms use computers to control the light, temperature and humidity . Using this technology a new, virus-free potato can be produced every 40 to 50 days instead of the previous yearly crop. Once seeds of some vegetables and crops are sent into space and back, _ . A) all of them don't produce bigger crops B) they are all better than before going to space C) small changes are caused in the seeds because of radiation and low gravity D) they produce much more and grow faster than normal seeds

Searching for airfares often seems like a game that passengers are bound to lose. Prices change from day to day, even minute to minute. Looking through multiple websites for the best deal can be a big challenge. Even when you do book, there's no guarantee that you are going to get the best price. "You just don't know when to _ . It's not like buying anything else I can think of," said George Hobica, founder of Airfarewatchdog.com. Harriet Levy paid $179 for a recent round-trip flight on American Airlines between New York and Fort Lauderdale, Florida. Sitting just one row behind her, Shirley Harrison paid $215. A few rows back, Ellis and Dianne Traub paid $317 each. There were at least 12 fares on the flight, ranging from $169 to $360. There's no reason for it, Harrison said. Fares can fluctuate significantly in just a few hours. One Delta flight from New York to Los Angeles jumped from $755 to $1,143 from a Friday to Saturday in late April, then fell to $718 on Sunday. The flight was one of a dozen the Associated Press followed over three months for a vacation between July 16 and 22. The number one finding: avoid booking tickets on weekends. It's the most expensive time to buy. There's no way to guarantee the best fare. But before booking, travelers should pay attention to this additional advice: * Book on Tuesday, Wednesday and Thursday. That's when airlines most often offer sales. * Buy in advance, but not too early. The best time is four to six weeks before traveling. In general, prices for any given flight are highest eight to 10 weeks and two to three weeks in advance. * Make use of social media. Airlines are giving more benefits like exclusive sales to travelers who interact with them on Twitter and Facebook. Those specials are often gone within hours. * The so-called discount airlines - JetBlue, Air-Tran, Southwest and Frontier - adjust their fares less frequently than other airlines, so you can feel more confident that the price will stay the same. But their prices aren't always the lowest.... By using a lot of figures, the author intends to _ . A) show there is standard price for every single airline B) discover the rules behind airfares C) guarantee passengers a low price D) prove airfares can vary widely
