    People need to seek out new foods because the world has so many mouths to feed. As of 2015, there are more than seven billion people on Earth, according to the United Nations. And by 2100 that number may double. Feeding all of these people means not only improving the way foods are grown, but also finding new sources of nutrition.

    And that quest is becoming ever more urgent. If nothing changes, within 35 years, the world's appetite will be greater than the amount of foods produced. That's according to a report released last year. It was prepared by the Global Harvest Initiative, a private agriculture group based in Washington, D.C.

    Global warming, too, is changing food production. Scientists predict that rising temperatures will reduce the growth of important crops like wheat, corn and soybeans. Low income developing countries will be hit the hardest. When harvests fall, crops become more expensive. And since those foods are also used to feed animals like cows and pigs,meat prices too, will rise.

    All over the world, researchers are racing against the clock to figure out how best to feed more people in a fast­changing world. And some surprising ideas have begun to come up. Two years ago, scientists introduced the first burger made from meat grown in a lab. The project cost more than $300,000, but it's a start. Other researchers are developing seeds that can survive high temperatures and drought. Still other are finding ways to improve the genes of meat animals so they produce more meat and can stand the heat.

    A gloomy(悲观的) forecast for the planet isn't the only reason to study foods for the future. It's a creative quest that will inspire people who can think in new ways about existing plants and animals—even insects. These researchers have used their talents in ways that even they never would have predicted.

(1)、How does global warming affect low­income developing countries?

a.Increase meat prices.

b.Raise the temperature.

c.Reduce the growth of crops.

d.Lead to the high cost of life.

e.Cause a higher price for crops.

Movie

Pete's Dragon

    Pete, played by Oakes Fegley, ventured into the water with his dragon pal, Elliot, in the new movie Pete's Dragon. The film brought an animated dragon, Elliot, and his human best friend, Pete, together. Shooing it took a lot of imagination for Oakes Fegley, the 11-year-old actor who played Pete, and Oona Laurence, the 13-year-old actress who played Natalie. She discovered Pete and Elliot in the woods.

    Kubo's Great Quest(寻找)

    The movie was about a young boy named Kubo, who live with his mother in a quite village in ancient Japan. After accidentally calling for a vengeful spirit from the past, Kubo set off on a heroic quest to find a magical suit of armor(盔甲) once worn by his father. Along the way, he gained two animal companions, Monkey and Beetle. Their journey was filled with magic, music, and the telling of many stories.

    Ice Age: Collision Course

    When the original Ice Age film was released in 2002, an animated herd of prehistoric animals took the world by storm. Fast-forward 14 years and the fifth movie in the Ice Age franchise(获特许经营权的企业)was hitting theaters. Ice Age: Collision Course followed those same beloved mammals that moviegoers have watched grow up. This time around, it isn't global warming that threatened the herd, but a big planet that's headed toward Earth.

    Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son: suddenly he seemed to be talking far more to his friends than to his parents. “The door to his room is always shut”, Joanna noted.

    Tina and Mark noticed the same changes in their 14-year-old daughter. “She used to cuddle up (依偎) with me on the sofa and talk,” said Mark, “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which.”

    Before age 11, children like to tell their parents what's on their minds. “In fact, parents are first on the list,” said Michael Riera, writer of Uncommon Sense for Parents with Teenagers. “This completely changes during the teen years.” Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”

    Parents who know what's going on in their teenagers' lives are in the best position (位置) to help them. To break down the wall of silence, parents should produce chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental (精神上的) break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.

    Parents and kids today dress alike, listen to the same music, and are friends. Is this a good thing? Sometimes, when Mr. Ballmer and his 16-year-old daughter, Elizabeth, listen to rock music together and talk about interests both enjoy, such as pop culture, he remembers his more distant relationship with his parents when he was a teenager.

    “I would never have said to my mom, 'Hey, the new Weezer album is really great. How do you like it?''' says Ballmer. “There was just a complete gap in taste.”

    Music was not the only gulf. From clothing and hairstyles to activities and expectations, earlier generations of parents and children often appeared to move in separate orbits.

    Today, the generation gap has not disappeared, but it is getting narrow in many families. Conversations on subjects such as sex and drugs would not have taken place a generation ago. Now they are comfortable and common. And parent-child activities, from shopping to sports, involve a feeling of trust and friendship that can continue into adulthood.

    No wonder greeting cards today carry the message, “To my mother, my best friend.”

    But family experts warn that the new equality can also result in less respect for parents. “There's still a lot of strictness and authority on the part of parents out there, but there is a change happening,” says Kerrie, a psychology professor at Lebanon Valley College. “In the middle of that change, there is a lot of confusion among parents.”

    Family researchers offer a variety of reasons for these evolving roles and attitudes. They see the 1960s as a turning point. Great cultural changes led to more open communication and a more democratic process that encourages everyone to have a say.

    “My parents were on the 'before' side of that change, but today's parents, the 40-year-olds, were on the 'after' side,” explains Mr. Ballmer, “It's not something easily accomplished by parents these days, because life is more difficult to understand or deal with, but sharing interests does make it more fun to be a parent now.”

    The fence was long and high. He put the brush into the whitewash and moved it along the top of the fence. He repeated the operation. He felt he could not continue and sat down.

    He knew that his friends would arrive soon with all kinds of interesting plans for the day. They would walk past him and laugh. They would make jokes about his having to work on a beautiful summer Saturday. The thought burned him like fire.

    He put his hand into his pockets and took out all that he owned. Perhaps he could find some way to pay someone to do the whitewashing for him. But there was nothing of value in his pockets-nothing that could buy even half an hour of freedom. So he put the bits of toys back into his pockets and gave up the idea.

    At this dark and hopeless moment, a wonderful idea came to him. It filled his mind with a great, bright light. Calmly he picked up the brush and started again to whitewash.

    While Tom was working, Ben Rogers appeared. Ben was eating an apple as he walked along the street. As he walked along it, he was making noises like the sound of a riverboat. First he shouted loudly, like a boat captain. Then he said "Ding—Dong-Dong", "Ding—Dong— Dong" again and again, like the bell of a riverboat. And he made other strange noises. When he came close to Tom, he stopped.

    Tom went on whitewashing. He did not look at Ben. Ben stared a moment and then said: "Hello! I'm going swimming, but you can't go, can you? "

    No answer. Tom moved his brush carefully along the fence and looked at the result with the eye of an artist. Ben came nearer. Tom's mouth watered for the apple, but he kept on working.

    Ben said, "Hello, old fellow, you've got to work, hey?"

    Tom turned suddenly and said, "Why, it's you, Ben! I wasn't noticing."

    "Say—I'm going swimming. Don't you wish you could? But of course you'd rather work—wouldn't you? Of course you would."

    Tom looked at the boy a bit, and said, "What do you call work?"

    "Why, isn't that work?"

    Tom went back to his whitewashing, and answered carelessly.

    "Well, maybe it is, and maybe it isn't. All I know is, it suits Tom Sawyer."

    "Oh come, now, you don't mean to say that you like it?

    The brush continued to move.

    "Like it? Well, I don't see why I shouldn't like it. Does a boy get a chance to whitewash a fence every day?"

    Ben stopped eating his apple. Tom moved his brush back and forth, stepped back to look at the result, added a touch here and there, and stepped back again. Ben watched every move and got more and more interested. Soon he said, "Say, Tom, let me whitewash a little."

    Tom thought for a moment, and was about to agree, but he changed his mind.

    "No-no-it won't do, Ben. You see, Aunt Polly wants this fence to be perfect. It has got to be done very carefully. I don't think there is one boy in a thousand, maybe two thousand, that can do it well enough."

    "No——is that so? Oh come, now——let me just try. Only just a little."

    "Ben, I'd like to, but if it isn't done right, I'm afraid Aunt Polly …"

    "Oh, I'll be careful. Now let me try. Say—I'll give you the core of my apple."

    "Well, here—No, Ben, now don't. I'm afraid …"

    "I'll give you all of it."

    Tom gave up the brush with unwillingness on his face, but joy in his heart. And while Ben worked at the fence in the hot sun, Tom sat under a tree, eating the apple, and planning how to get more help. There were enough boys. Each one came to laugh, but remained to whitewash. By the time Ben was tired, Tom sold the next chance to Billy for a kite; and when Billy was tired, Johnny bought it for a dead rat——and so on, hour after hour. And when the middle of the afternoon came, Tom had won many treasures.

    And he had not worked. He had had a nice idle time all the time, with plenty of company, and the fence had been whitewashed three times. If he hadn't run out of whitewash, Tom would have owned everything belonging to his friends.

    He had discovered a great law of human action, namely, that in order to make a man or a boy want a thing, it is only necessary to make the thing difficult to get.
