A Battery’s Nightmare
Portable electronics that can be carried about easily are only as good as their batteries (电池) and, let’s face it, batteries aren’t very good, especially when compared with, say, petrol, which packs 100 times a battery’s energy into an equal space. That’s why a large group of mechanical engineers (centered at the Massachusetts Institute of Technology, but with partners at other universities and companies) are hard at work in an effort to replace batteries with a tiny engine that runs on fuel. Imagine a battery-free life! When the fuel runs out in your mobile phone, you just fill up and go.
The engine---about the size of a ten-cent coin---starts with a combustion chamber (燃烧室) that burns hydrogen. Its tiny parts are etched (蚀刻) onto silicon wafers (硅片) in the same manner that computer parts are etched onto integrated circuits (集成电路). The first engine is made up of five wafers. And since these wafers could be produced in much the same way as computer chips, they could probably be produced quite cheaply.
But the devil in all this nice detail is efficiency. Tiny engine parts don’t always behave like the bigger parts of the first engine. Something between the parts can slow down the works, according to Columbia University Professor LucFrechette, one of the engine’s designers. Extreme heat from the combustion chamber is also a problem, often leaking to other parts of the engine.
The scientists’ goal is to create an engine that will operate 10 times better than batteries operate. Frechette says that a complete system, with all parts in place and working, will be set up in the next couple of years, but commercial models aren’t likely until at least the end of the next ten years.

Mo Yan’s winning of the 2012 Nobel Prize in Literature shows the world’s recognition of China’s contemporary literature, according to the China Writers Association.

The other day I heard a few local musicians talking:
"I hate all the pianos in this town and I hate that rubbish they play on the radio .They cannot every understand rhythm（韵律)"
"Nobody wants to pay musicians anything. I'm sick of all the people who want you to play without paying you."
One younger musician said, "There are several clubs who want me to play for a few nights a month and I'm trying to find other places to play .I'm also planning to join in several summer festivals this year."
I really liked what the younger musician said so I made friends with him.
Attitudes are important. Whether they're positive or negative(消极) they're all rubbing off on you,If you're around people who are always complaining or blaming others, it is possible that you will start doing the same as well. If you spend lots of time with people who don't support your dreams, it is time to take a look at the people you call " friends".
There is an easy exercise you can try. Make a list of the people who you often stay with, and simply stop , spending time with the negative ones on your list. Set a new standard for yourself and don't become friends with people who fall below that standard.
Of course, this exercise is entirely different from making friends only for the good of oneself. We really should try to help and spend time with those who are working towards a goal or dream.The musicians' conversation at the beginning is there to show that
| A．musicians' living conditions are not good |
| B．people in that town have poor taste in music |
| C．young people are more likely to succeed |

| A．they'll have an influence on you |
| B．they'll help you realize your dreams |

Why did the author want to make friends with the younger musician?
| A．He is more active than the others. |
| B．He can earn more than the others. |
| C．His attitude is more positive than the others. |
| D．He has more things to do than the others. |

| A．improve your ability to make friends |
| B．make the right kind of friends for sure |

"If there is one thing I'm sure about, it is that m a hundred years from now we will still be reading newspapers. It is not that newspapers are a necessity. Even now some people get most of their news from television or radio. Many buy a paper only on Saturday or Sunday. But for most people reading a newspaper has become a habit passed down from generation to generation.
The nature of what is news may change .What basically makes news is what affects our lives - the big political stories, the coverage of the wars, earthquakes and other disasters, will continue much the same. I think there will be more coverage of scientific research, though .It's already happening in areas that may directly affect our lives, like genetic（基因的） engineering. In the future, I think there will be more coverage of scientific explanations of why we feel as we do - as we develop a better understanding of how the brain operates and what our feelings really are.
It's quite possible that in the next century newspapers will be transmitted（传送）electronically from Fleet Street and printed out in our own home. In fact ,I'm pretty sure how it will happen m the future. You will probably be able to choose from a menu, making up your own newspaper by picking out the things you want to read - sports and international news, etc.
I think people have got it wrong when they talk about competition between the different media（媒体）．They actually feed off each other. Some people once foresaw that television would kill off newspapers, but that hasn't happened. What is read on the printed page lasts longer than pictures on a screen or sound lost in the air. And as for the Internet. it's never really pleasant to read something just on a screen.What is the best title for the passage?
| A．The Best Way to Get News | B．The Changes of Media |
| C．Make Your Own Newspaper | D．The Future of Newspaper |
In the writer's opinion, in the future, _______.
| A．more big political affairs, wars and disasters will make news |
| B．newspapers will not be printed in publishing houses any longer |
| C．newspapers will cover more scientific research |
| D．more and more people will watch TV |
What will probably be on in the newspaper made by yourself?
| A．Sports and international news. | B．A menu of important news. |
| C．The most Important news. | D．what you are interested in. |
From the passage, we can infer ________.
| A．newspapers will win the competition among the different meclia |
| B．newspapers will stay with us together with other media |
| C．television will take the place of newspaper |
| D．the writer believe some media will die out |
The phrase "feed off" in the last paragraph means ________ .
| A．depend on | B．compete with | C．fight with | D．kill off |

Two weeks before Christmas, Mother told me we were going to my grandmother's house for the holiday. Grandma and Uncle Henry lived on a farm some 15 miles out of town They had no electricity or running water and _ what I considered the "good things" in life. They made no plans for Christmas When Christmas Eve arrived, Mom told me in her best "I-mean-it" voice to _ all the decorations from our tree. She packed those up all the materials for a _ turkey dinner.
Christmas morning perfectly with the sun shining brightly across a fresh blanket of snow. _ I was angry silently in the backseat of the car as we made our _ to grandma's. This was going to be the _ Christmas ever! Grandma was _ to see us as we walked up to her door. "What on earth are you doing here?" she said." We weren't expecting . It's Christmas, and I don't even have a turkey to cook for you." "I knew ." Mom said as we set boxes of goodies(好吃的) on the kitchen table. "That's _ we brought all with us." "We _ have a tree" Mom insisted. " what will we do with all these decorations?" Uncle Henry quickly caught Mom's spirit. He called me to join him, and we found a perfect Christmas tree in the woods. Soon the house _ fresh and piney as we decorated the pine tree, and the day a festive air . The turkey dinner was very good, too. I was actually beginning to enjoy this unusual Christmas day!
Dessert was almost forgotten _ Mom came out with the final surprise-a flaming (色彩鲜明的)pudding! "Merry Christmas, mother," Mom said. "Dear me!" Grandma said with her mouth wide open. "I haven't seen a flaming pudding since I left England before I was married." Tears of filled her eyes. I could not keep the tears . my eyes, either. I knew then that Mom had also given me the best Christmas present ever.
She had taught me what a beautiful thing it is to give.
