Mark Twain was a great writer. He was born in 1835 in the USA. He was also a famous speaker. He was famous for his sense of humour. Many people liked to listen to his talk because he liked to tell some interesting stories to make people laugh all the time.

One day, Mark Twain was going to a small town because of his writing. Before he was going to leave, one of his friends said to him that there were always a lot of mosquitoes in the town and told him that he'd better not go there. Mark Twain waved his hands and said," It doesn't matter. The mosquitoes are no relatives of mine. I don't think they will come to visit me."

After he arrived at the town, Mark Twain stayed in a small hotel near the station. He went into his room, but when he was just about to have a rest, quite a few mosquitoes flew around him. The waiters felt very sorry about that." I'm very sorry，Mr. Mark Twain. There are too many mosquitoes in our town," one of them said to him.

Mark Twain, however, made a joke, saying to the waiter, "The mosquitoes are very clever. They know my room number. They didn't come into the wrong room." What he said made all the people present laugh heartily.

But that night Mark Twain slept well. Do you know why? That was because all the waiters in the hotel were driving the mosquitoes away for him during the whole night.

University Room Regulations

Approved and Prohibited(禁止) Items

The following items are approved for use in residential rooms: electric blankets, hair dryers, personal computers, radios, televisions and DVD players. Items that are not allowed in student rooms include: candles, ceiling fans, fire works, waterbeds, sun lamps and wireless routers. Please note that any prohibited items will be taken away by the Office of Residence Life.

Access to Residential Rooms

Students are provided with a combination for their room door locks upon check-in. Do not share your room door lock combination with anyone. The Office of Residence Life may change the door lock combination at any time at the expense of the resident if it is found that the student has shared the combination with others. The fee is $25 to change a room combination.

Cooking Policy

Students living in buildings that have kitchens are only permitted to cook in the kitchen. Students must clean up after cooking. This is not the responsibility of housekeeping staff. Kitchens that are not kept clean may be closed for use. With the exception of using a small microwave oven to heat food, students are not permitted to cook in their rooms.

Pet Policy

No pets except fish are permitted in student rooms. Students who are found with pets, whether visiting or owned by the student, are subject to an initial fine of $ 100 and a continuing fine of $50 a day per pet. Students receive written notice when the fine goes into effect. If, one week from the date of written notice, the pet is not removed, the student is referred to the Student Court.

Time Travel

If you could travel in time, where would you go? Perhaps you would watch an original performance of a Shakespeare's play in Elizabethan England? What about hanging out with Laozi in the Spring and Autumn Period? Or maybe you'd voyage far ahead of the present day to see what the future holds.

The possibility of time travel is indeed appealing. Stories exploring the subject have been around for hundreds of years. Perhaps the best known example is science fiction novel The Time Machine, which was written by H.G.Wells and published in 1895 for the first time. It was adapted into at least two feature films of the same name, as well as two television versions, and a large number of comic book adaptations. It is generally credited with the popularization of the concept of time travel using a vehicle that allows an operator to travel purposefully and selectively. The term "time machine", coined by Wells, is now universally used to refer to a vehicle transporting people into the far future.

But could time travel actually be possible? Some scientists say yes, in theory. They propose using cracks in time and space called "wormholes", which could be used as shortcuts to other periods. Einstein's theory of relativity allows time travel in extreme circumstances. And British physicist Stephen Hawking says you could travel into the future with a really fast spaceship — going at nearly the speed of light. Though building such a spaceship would of course be no simple task.

Even if you could travel into the past, there is something called the "grandfather paradox". It asks what would happen if a time traveler were to go back in time and have his own grandfather killed for some reason, and therefore prevent himself from being born．If the time traveler wasn't born, how would he travel back in time?

And would you really like to visit the future? In H. G. Wells' book, the main character travels into distant time where he arrives at a beach and is attacked by giant crabs. He then voyages 30 million years into the future where the only living thing is a black object with tentacles(触角). If that's what's in store, maybe we are better just living in the present day after all.

Dyslexia is a problem that restricts the ability to recognize words and connect sounds with letters when people read. People with this learning disorder may also have problems when they write. Dyslexia is not related to eyesight or intelligence. The problem involves areas of the brain that process language. Brain scientists are studying whether they can predict which young children may struggle with reading to provide them with early help. John Gabrieli at the Massachusetts Institute of Technology is leading the study of five-year-olds in about twenty schools in the Boston area.

They studied in the schools with kindergartens. And for all the children joining in the study, they give them a brief set of paper-and-pencil tests to look at which children appear to be at some risk for struggling to read. So far, 50 of them have been examined in a scanner, a special machine, to show brain activity. Written tests are not always able to identify dyslexia or other problems, while brain scans may offer a more scientific way to identify problems. And with reading problems, early identification is important. When it comes to helping children overcome reading difficulties, the younger the child, the more effective they are.

Reading problems are not usually identified until a child is in the third or fourth grade. The later children are recognized as poor readers, the less treatment can help. And, as Professor Gabrieli points out, poor reading can make education a struggle. Reading is everything. Even math and science have textbooks.

While the children are given tasks related to reading, the brain scans measure the extent to which certain parts of the brain become active while the children do the work. The scientists say they are pleased with early results from the study, but have a long way to go.

When I was thirteen, my family moved from Boston to Tucson, Arizona. 1the move, my father2us in the living­room on a freezing January night. My sisters and I sat around the fire, not3that the universe would suddenly change its course." In May, we're4to Arizona."

The words, so small, didn't seem5enough to hold my new life. But the world changed and I awoke on a train moving across the country. I watched the6change from green trees to flat dusty plains to high mountains as I saw strange new plants that7mysteries yet to come. Finally, we arrived and8into our new home.

While my older sisters were9at the loss of friends, I10explored our new surroundings.

One afternoon, I was out exploring11and saw a new kind of cactus(仙人掌). I crouched (蹲) down for a closer look. "You'd better not12that."

I turned around to see an old woman.

"Are you new to this neighborhood?" I explained that I was, 13, new to the entire state.

"My name is Ina Thorne. Have you got used to life in the14? It must be quite a15after living in Boston."

How could I explain how I16the desert? I couldn't seem to find the right words.

"It's vastness," she offered." That vastness when you 17on the mountains overlooking the desert—you can18how little you are in comparison with the world.19, you feel that the possibilities are limitless."

That was it. That was the feeling I'd had ever since I'd first seen the mountains of my new home. Again, my20would change with just a few simple words.

"Would you like to come to my home tomorrow? Someone should teach you which plant you should and shouldn't touch."

As we all know, the temperature of the earth has risen. That probably does not seem much to you or me, but it is a rapid increase when (compare) to other changes. There is no doubt it is human activity that has caused this global warming rather than a random but (nature) phenomenon.

Some byproducts of the burning of fossil fuels are called "greenhouse" gases, the most important one of which is carbon dioxide. More heat energy tends to be trapped in the atmosphere (cause) the global temperature to go up.

Some scientists accept the idea that the problem begins when we add huge(quantity) of extra carbon dioxide into the atmosphere. However, some scientists are opposed  this view and believe that we should not worry about high levels of carbon dioxide in the air.

Everyone knows, the global warming connects the nature. In the text The Power of Nature, we are also aware that the writer has an exciting job. (collect) and evaluated the information, the writer helps other scientists to predict where lava from the volcano will flow next and how fast. His work has saved many lives because people in the path of the lava can be warned to leave(they) houses. (fortunate), they cannot move their homes out of the way, and many houses have been covered with lava or burned to  ground.
