What does an astronaut eat in space? This is a question that will puzzle many, as people rarely think of that. In the early space-travel years, astronauts ate dehydrated (脱水的) foods that were eaten through straws （吸管）. In today’s space-age, the food that they eat is totally different. They eat food in the same way as people do on Earth.
Astronauts are able to prepare and eat a variety of foods in space. Some can be eaten in their natural form, like fruits, while some need to add water, like noodles. However, there are no refrigerators, so the food has to be prepared and eaten without being stored for a long time. When the astronauts are hungry, they simply eat the food by opening the food packages and with a fork, knife, and spoon.
Just like people on Earth, astronauts also eat three meals a day which include breakfast, lunch and dinner. Sometimes they also eat snacks. The US space agency NASA has found out that an astronaut’s diet reduces by about 70% on a space mission, though he has a wide range of foods to choose from like nuts, chicken, beef, seafood, and candies. Drinks in the spaceship include coffee, tea, juices, and lemonade.
Astronauts can also request a particular food that they would like to have in space. Scientists are always experimenting and trying out different space foods that can be offered to astronauts when on space missions.

Researchers found that people become happier and experience less worry after they reach the age of fifty. In fact, they say by the age of eighty-five, people are happier with their life than they were when they were eighteen years old.
The findings came from a survey of more than three hundred forty thousand adults in the United States. The Gallup Organization questioned them by telephone in two thousand eight. At that time, the people were between the ages of eighteen and eighty-five.
The researchers asked questions about emotions like happiness, sadness and worry. They also asked about mental or emotional stress.
Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of twenty-two and twenty-five.
The findings showed that stress levels dropped sharply after people reached their fifties.
Happiness was highest among the youngest adults and those in their early seventies. The people least likely to report feeling negative emotions were those in their seventies and eighties.
The findings appeared in the Proceedings of the National Academy of Sciences.
Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.
Professor Stone says the emotional patterns could be linked to changes in how people see the world, or maybe even changes in brain chemistry.
The researchers also considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age.
The study also showed that men and women have similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men.What is the best title of the passage?

A heartless thief is believed to have crashed a fund-raiser and made off with a bag of cash meant to help a New York City firefighter pay for life-changing surgery for his 9-year-old son. But little Aidan Sullivan -- who was born with a facial defect and no right ear -- yesterday put up a brave front, with a message for the crook(thief): "I'm going to kick your butt!"
"I want to look normal," said Aidan, whose father, Tim, is a firefighter in the Bronx. The third-grader has hemi facial micro soma, in which one half of the face doesn't develop correctly.
Last weekend, family friend Peter Drake, a Ridgefield, Conn., firefighter, hosted a fund-raiser, collecting between $8,000 and $9,000. But when the party at a Danbury, Conn., Irish cultural center was over, the money had disappeared.
"At the end of the night, all the money that was donated was put in a zippered bag," said Tim Sullivan. "A bartender gave the bag to Pete... He had it in his hands. He put it down to go do something, and when he came back, he saw that it was missing."
Sullivan said his longtime friend -- who has had fund-raisers to pay for Aidan's 10 previous surgeries -- is "devastated."
"Pete was so upset. He kept saying, 'I let Aidan down, I let Aidan down,” Colleen Sullivan, 40, recalled.
"We even went Dumpster diving, in case it was thrown out."
The Sullivans plan to go ahead with the March 1 surgery led by specialists at NYU's Langone Medical Center in Manhattan. The money would have offset the $10,000 to $15,000 that insurance doesn't cover. Yesterday, Aidan said he's not a fan of hospitals and doesn't like to be away from his sister, Kaylee, 4. But he's willing to do it. "I'm excited," he said. "Finally, an ear."Where do you probably read this text from?

In the United States you will find yourself being urged from every page of every newspaper and every television station to buy all kinds of goods.
Not only is there a wide range of prices for goods in America, there is also a wide range in the quality of goods offered for sale. Unlike some countries, Americans generally pay the price of a product without question, instead of trying to get a lower price by bargaining. However, there are many “sales” in the United States, during which time stores will lower their normal prices. This may all be very confusing to visitors. How are you going to know how to “get your money’s worth” when you shop? Perhaps the best advice is: Don’t hurry. Visit various stores and determine the quality of goods. Read the advertisements so that you can compare prices.
There is a great variety of shops in the United States, ranging from very large stores called “department stores” to very small shops. There are “discount houses” offering goods at low prices, and “dime stores” specializing in a wide range of inexpensive items.
Most department stores in large cities carry better quality products at higher prices. However, they offer the shoppers great convenience since they contain such a wide variety of products.
If convenience isn’t as important to you as price, you may want to shop in discount houses. These stores have nearly as great a variety of goods as department stores, but offer lower prices. They can do so for several reasons. They don’t offer the same services to buyers that department stores do; there may be fewer sales people; and the store probably doesn’t deliver purchases.
Another popular shop is the “dime store”. No longer selling many things for five or ten cents, these stores got their name in the last century when it was decided that a small profit on a great quantity of goods would be better than a large profit on fewer sales. Dime stores specialize in a wide variety of inexpensive items and today, prices range from a quarter or 50 cents up to several dollars.

| B．They make big profits by selling some goods. |
| C．They provide goods with a price lower than 50 cents. |
