Dear John,
I was very happy to receive your e- mail in that you asked me about my life. As a Senior 3 student, I was now working very hard to preparing for the National College Entrance Examination. In class, I listen to the teachers attentively and take notes careful. Out off class, I take an active part in various sport to keep healthy, which, I believe, is very important for my study.
Both my teachers and parents give me many support. With their help and encouragement, I have been made great progress and been able to build up our confidence. I have decided to attend medical university.
Best wishes,
Yours，
Mary

Muzak
The next time you go into a bank, a store, or a supermarket, stop and listen. What do you hear? 1.. It's similar to the music you listen to, but it's not exactly the same. That's because this music was especially designed to relax you, or to give you extra energy. Sometimes you don't even realize the music is playing, but you react to the music anyway.
Quiet background music used to be called "elevator (电梯) music" because we often heard it in elevators. But lately we hear it in more and more places, and it has a new name "Muzak". About one-third of the people in America listen to "Muzak" every day. The music plays for 15 minutes at a time, with short pauses in between. It is always more lively between ten and eleven in the morning, and between three and four in the afternoon, when people are more tired. 2..
If you listen to Muzak carefully, you will probably recognize the names of many of the songs. Some musicians or songwriters don't want their songs to be used as Muzak, but others are happy when their songs are chosen. Why? 3..
Music is often played in public places because it is designed to make people feel less lonely when they are in an airport or a hotel. It has been proven that Muzak doeswhat it is designed to do. Tired office workers suddenly have more energy when they hear the pleasant sound of Muzak in the background. 4.. Supermarket shoppers buy 38 percent more groceries.
5.. They say it's boring to hear the same songs all the time. But other people enjoy hearing Muzak in public places. They say it helps them relax and feel calm. One way or another, Muzak affects everyone. Some farmers even say their cows give more milk when they hear Muzak!
A.Some people don't like Muzak.
B.The music gives them extra energy.
C.Music is playing in the background.
D.Factory workers produce 13 percent more.
E.Muzak tends to help people understand music better.
F.They get as much as $4 million a year if their songs are used.
G.Muzak is played in most of the big supermarkets in the world.
A new study shows that rising levels of planet-warming gases may reduce important nutrients（营养物质）in food crops
Researchers studied the effects of carbon dioxide on rice， In the experiment， scientists grew 18 kinds of rice in fields in China and Japan．They set carbon dioxide levels to what scientists are predicting for our planet by the end of the century．Rice grown under high carbon dioxide conditions had，on average，13 t0 30 percent lower levels of four B vitamins and 10 percent less protein（蛋白质）The crops also had 8 percent less iron and 5 percent less zinc than rice grown under normal conditions However， vitamin E leveLs increased by about 13 percent on average．
The researchers said the effects of planet-warming gases would be most sevcre for the poorest citizens in some of the least developed countries．These people generally eat the most rice and have the least complex diets．That includes abour 600 million people in Indonesia， Cambodia，Myanmar，Bangladesh，Laos and other nations，mainly in Southeast Asia．
Other studies have shown that higher temperatures from climate change and weather extremes will reduce food production．But scientists are finding that rising levcls of carbon dioxide and other planet-warming gases threaten food quality．
Earlier studies showed that wheat，rice，field peas and soybeans grown under high carbon dioxide conditions all had Iower levels of protein and mincrais．Scientists predicted that almost 150 million people might be at risk of having too little protein or zinc in their diet by 2050．
The new study suggests a way to lower the nutritional harm of climate change．That is to grow different forms of rice that can adapt to higher carbon dioxide levels．
1.Growing rice under high carbon dioxide conditions may____．
A.increase iron in the rice
B.make it less nutritious
C.cause losses of Vitamin E
D.make it more delicious
2.How can people reduce the nutritional harm of climate change？
A.By importing rice from China and Japan．
B.By taking other kinds of food instead of rice．
C.By avoiding eating rice from Southeast Asia．

3.What’s the author’s purpose of writing the text？
A.To infom readers what nurrients food crops contain．

C.To share the results of some studies on people’s diets．
D.To tell readers where food crops are mainly produced．
4.In which part of a magazine can you read the text？

Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.
While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.
The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn’ t just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.
Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.
Fellow Robots is one company bringing social robots to the market. The company’ s “ Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product’ s location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.
The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. “ We have technologies to train social robots to do things not for us, but with us,” said Breazeal.
1.How are social robots different from household robots?
A.They can control their emotions.
B.They are more like humans.
C.They do the normal housework.
D.They respond to users more slowly.
2.What can a Jibo robot do according to Paragraph 3?
A.Communicate with you and perform operations.
B.Answer your questions and make requests.
C.Take your family pictures and deliver milk.
D.Obey your orders and remind you to take pills.
3.We can learn from the last paragraph that social robots will ______.
A.train employees
B.be our workmates
C.improve technologies
D.take the place of workers
4.What does the passage mainly present?
A.A new design idea of household robots.
B.Marketing strategies for social robots.
C.Information on household robots.
D.An introduction to social robots.
