Input: Consider Input: Article: Yu Pengnian is an 88-year-old real estate Chinese businessman. He amassed a fortune of $1.3 billion dollars during his career but instead of keeping the money and living like an emperor, he decided to give it all away. All of his fortune will be spent on helping poor Chinese students get a better education. And Yu isn't the only super-rich person in China who has this spirit of giving. Chen Guangbiao, a Jiangsu recycling tycoon, has given millions of dollars to charity and promises to give all of his money to charity when he dies. Yu and Chen are among the many businessmen who have become prosperous during China's economic rise. An American business magazine, Forbes, estimates that there are 117 billionaires in China and hundreds of thousands of millionaires. What sets Yu and Chen apart from the rest, though, is their tremendous generosity(,) when it comes to donating money to charity. Last week Bill Gates and Warren Buffett came to Beijing. Gates and Buffett, two of the world's richest men, are also the world's biggest philanthropists. They invited fifty of China's richest people to have dinner with them and talk about the spirit of giving. At first, only a few people accepted their invitation. It seemed some of the invited guests were afraid that Buffett and Gates were going to pressure them into giving their wealth to charity. A lot of people are angry at the billionaires who are not willing to give away their fortunes. They _ hem for being miserly and not caring about the poor and the less fortunate. But I think this criticism is wrong. A gift, any gift, should come from the heart. Instead of criticism, these reluctant billionaires should be encouraged to follow the examples of Yu Pengnian and Chen Guangbiao. Encouragement is always a better strategy than criticism. As we say in English, "You can catch more flies with honey than with vinegar."
Answer: helping poor Chinese students get a better education

Output: Yu Pengnian will spend all of his fortune in _

Input: Consider Input: Article: People who enjoy a dream-filled sleep are better at recalling information and making links between facts when they wake, scientists found. But recharging with a shallow nap offers no such mental improvement, the research suggests. The results of the study add to the evidence that Rapid Eye Movement (REM) sleep is very important to the brain's ability to strengthen memories. An average night's sleep includes four or five periods of REM sleep, but these tend to be longer towards the end of the night. This means that adults who get less than the recommended seven to eight hours a night -- and therefore inadequate REM sleep -- may be damaging their mind's ability to form strong memories. Although REM sleep is not classified as a type of deep sleep, it is only reached after the brain has passed through deep sleep stages. In the most recent study, participants were shown groups of three words -- such as "cookie", "heart", and "sixteen" -- and asked to find another word that can be associated with all three words. In this example, the answer would have been "sweet". They were tested once in the morning and then given the same task again in the afternoon. In between, some were allowed a nap with REM sleep, some a nap without REM sleep, while the others had a quiet rest period. The quiet rest and non-REM sleep groups showed no improvement in their test results, but the REM sleep group improved on their morning performance by an average of almost 40 percent. Dr Sara Mednick, a sleep researcher at the University of California who led the study, believes the formation of connections between previously unassociated information in the brain -- which leads to creative problem-solving -- is encouraged by mental changes which occur during REM sleep. People woken while their closed eyes made rapid movements recalled much more color1ful and detailed dreams than people woken during other stages of sleep.
Answer: sleep with four or five periods of REM
Output: According to the passage, to have a good memory, a person had better _ at night.
