说起紫土豆很多人以为是近年才有的新品种，其实紫土豆并不是什么稀奇玩意儿，它是秘鲁的一个古老品种，明朝的时候就从国外引进种植，不过因产量不高，才逐渐被淘汰。

紫土豆种植创业者彭洁告诉记者，“紫土豆中富含花青素和硒元素，营养价值极高，与现代人的饮食需求正好契合。看清市场需求后，虽然           ， 彭洁还是借款开始试种紫土豆。收获后，彭洁并没有           别人的做法——到市场上贩卖，而是拿着样品找订单。让彭洁没想到的是，她一下就以普通马铃薯7～8倍的价格，拿下深圳一家公司300吨的订单。接到订单后，彭洁           ， 欢喜紫色土豆销售前景广阔，（                    ）。在与对方协议三年内完成订单后，彭洁便带领创业团队在四川古蔺县箭竹乡建立基地。

对紫土豆了解越多，彭洁就越兴奋，她一头扎进了紫土豆创业大潮。至今 ， 她和团队已经近7年从事了马铃薯研究工作，对紫色马铃薯的高营养价值和市场前景开展调查研究。“花青素对身体的益处人们都已           ， 紫色马铃薯就富含花青素，并且口感好，非常受欢迎。”现在，韩洁正带领当地的乡亲们大踏步地走在脱贫致富的路上。

    While serious training is important for all dogs, playtime is just as important.  Use these games to help teach your dog how to play.

    Hide and Seek

     Hide and seek isn't just for kids. Dogs can really enjoy this game. Pick up one of your dog's favorite toys or treats. Tell your dog to stay.  When you are ready, call your dog to come to you. If possible, squeak(使吱吱叫) the toy or shake the treats. Reward your dog with praise and the toy/treat when she finds you.

    Fetch

    Many dogs have a natural ability to fetch. Other dogs can be taught how.  Play indoors with a soft toy or outdoors in a fenced-in area with a ball or disc. For dogs that really love to run, try this game of fetch!

    Find the Treat

    Dogs have superior senses of smell, and most love to use their noses to find food. Let your dog use her brain and her nose to find hidden goodies. First, have your dog stay out of sight. Then, hide her favorite treats in different places around the room.  If help is needed, you can lead her around or point to areas for her to explore.

    Whatever the game, safety comes first! Remember to watch your dog for signs of exhaustion or overheating when you are playing. Stop if your dog seems tired or shows signs of anxiety.  When other dogs or people are around, it may create a dangerous distraction(分神).

A. Then, go to find a good hiding place.

B. Try different games to see which your dog responds to best.

C. A good game of fetch can be played almost anywhere.

D. You can include games in training as well.

E. Also be aware of your surroundings when playing with your dog.

F. Encourage your dog to play with other dogs.

G. Bring your dog back in and tell her to "go find!".

    最近，一档导演选角真人秀《演员请就位》发布宣传海报，海报上用醒目的字迹彰显着陈凯歌、李少红、赵薇、郭敬明四位导演对表演，对艺术创作的态度。每位导演的理念分别浓缩为一句口号，陈凯歌：“你是角色，不是角儿。”李少红：“不走心，就走人。”赵薇：“无惧表演，表演无矩，”郭敬明：“演技，就是颜值。”表演、艺术创作需要这样的理念，生活中其它行业也是如此。

The students and began to ask him questions.

    In the clinic, I asked if Michael could be retested, so the specialist tested him again. To my 1, it was the same score.

    Later that evening, I 2 told Frank what I had learned that day. After talking it over, we agreed that we knew our 3 much better than an IQ(智商) test. We 4 that Michael's score must have been a 5 and we should treat him 6 as usual.

    We moved to Indiana in 1962, and Michael studied at Concordia High School in the same year. He got 7 grades in the school, especially 8 biology and chemistry, which was a great comfort.

    Michael 9 Indiana University in 1965 as a pre-medical student. Soon afterwards, his teacher permitted him to take more courses than 10. In 1968, he was accepted by the School of Medicine, Yale University.

    On graduation day in 1972, Frank and I 11 the ceremony(典礼) at Yale. After the ceremony, we told Michael about the 12 IQ score he got when he was six. Since that day, Michael sometimes would look at us and say 13, "My dear mum and dad never told me that I couldn't be a doctor, not until after I graduated from medical school! "It is his special way of thanking us for the 14 we had in him.

    Interestingly, Michael then 15 another IQ test. We went to the same clinic where he had 16 the test eighteen years before. This time Michael scored 126, an increase of 36 points. A result like that was supposed to be 17.

    Children often do as 18 as what adults, particularly parents and teachers, 19 of them. That is, tell a child he is "20" and he may play the role of a foolish child.

    The United States has always been a country of many cultures. Before Europeans came to North America, many groups of Native Americans lived here. Different Native American groups had different cultures. The first Europeans in the United States were from England and Holland, but immigrants came from all European countries. Many people also immigrated from Asia and Africa. Sadly, many Africans were brought to the United States as slaves. Many immigrants come from Latin America too. Today, the United States has people from more cultures than ever.

    In the 19th century, people spoke of the United States as a “melting pot.” People thought that all immigrates should forget their native cultures and languages and become English-speaking Americans. They felt that people should assimilate-join American culture. However, not everyone wanted to assimilate completely. Many people tried to keep parts of their cultures, such as foods, customs, and languages. However, their children often forgot their parents' or grandparents' language. But most Americans, even those whose families have been here a long time, can tell the countries their relatives came from. And of course, new immigrants take great pride in their curare and language.

    For all of these reasons, melting pot is no longer a good way to describe the United States. Instead, people now call the United States a “salad bowl.” They say salad bowl because in a salad, you can still see all of the individual parts (lettuce, tomato, and so on), but all the different parts mixed together and begin to take on the flavor of one another.
