I love science and science fiction. Like many science fiction fans, I am fascinated by the possibility of time travel. However, one must combine romance with reasoning and look into the chances of time travel critically.
First of all, we must remember the whole universe is in motion. If we want to go back to yesterday, our "time machine" has to move back in time and space. If someone claimed he was at home when he suddenly travelled 200 years back in time, he either had an illusion or made the story up. Two hundred years ago, Earth was in a different place in space, so how can you travel back 200 years without moving in space? Don't get me wrong. I am not knocking the genius of science fiction writers. H.G. Wells's "The Time Machine" is a great work of fiction, but that’s all. I have read many other time travelling science fiction stories since reading H.G. Wells, but none address this problem of displacement.
My own argument for the impossibility of time travel is that physical states of the past no longer exist and those of the future are not here yet. To be able to move back and forth in time requires everything that has happened, is happening, and will happen everywhere in the whole universe at every single moment in time－past, present, and future－to be stored as a "reality" somewhere－like the save game file of a computer game that contains every single byte of information of the game at the point it was saved, but you would need an almost extremely large file and almost extremely many of them－so it can be re-entered and communicated with, and not just light signals for viewing. To me, I don’t buy it.
小題1:Which of the following can be the best title?
A．How to make time travel possible?
B．Why am I fascinated by time travel?
C．Why do I think time travel is not possible?
D．How to explain the possibility of time travel?
小題2:What’s the meaning of the underlined word “illusion”?
A．successB．dreamC．switchD．support
小題3: According to the author, which of the following is RIGHT?
A．We can go back to the past by time travel.
B．People can travel to the future by moving in space.
C．“The Time Machine” is nothing more than a science fiction.
D．Everything that happened, is happening and will happen can be stored somewhere.
小題4:In the author’s opinion, time travel might be possible if                            .
A．people could combine romance with reasoning
B．people could stop the movement of the whole universe
C．people could use time machine under the instruction of H.G. Wells
D．people could “save” everything in the past, present and future in a certain space

What I noticed first about my new parrot, Chico, was that he couldn’t fly. His wings had been cut short and he was stuck on the   1  just like us humans. When the weather turned nice, I took Chico outside. I sat him on a branch of a tree, hoping to make him   2 . At first he seemed   3 .

From that day on, whenever the weather was good I would let him out early and he would fly around and be back before dark. The   14  lasted for two months before suddenly Chico became   15 . The vet said that he had been infected with a disease from the pigeons in the neighborhood. Within a few days he died.
I was very sad. The   16  crossed my mind that if I had not set him free to fly, he would be still alive. But what   17  is there in being a bird if you can’t fly?

Until recently, I hadn’t done much community service．In face, I did nothing to benefit anyone but myself．My selfishness and laziness were clear before I received an assignment from my teacher．Each student was required to complete 10 hours community service．To me, 10 hours was a huge amount of time to spend helping others．Volunterring, for me, has been a truly life – changing experience．
My mom suggested that I organize a food drive（募捐活動(dòng)）in our development（新建筑宅區(qū)）and donate what I collected to a local shelter．Anything that would help finish the project seemed like a good idea, so I agreed．I made up flyers（傳單）asking for donations and placed flyers at every house in my neighborhood．

Science can’t explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.
Any owner will tell you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (緊張) levels and blood pressure in people ---half of them pet owners ---while they performed 5 minutes of mental arithmetic (算術(shù)) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed (放松)around pets, says Allen, who thinks it may be because pets don’t judge.
A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about I1 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn’t lose any more weight than those without dogs but, say researchers, got more exercise overall---mostly with their dogs --- and found it worth doing.
小題1:What does the text mainly discuss?
A．What pets bring to their owners.
B．How pets help people calm down.
C．People’s opinions of keeping pets.
D．Pet’s value in medical research.
小題2:We learn from the text that a person with heart disease has a better chance of getting well if _____.
A．he has a pet companion
B．he has less stress of work
C．he often does mental arithmetic
D．he is taken care of by his family
小題3:According to Allen, why did the people do better with pets around when facing stressful tasks?
A．They have lower blood pressure.
B．They become more patient.
C．They are less nervous.
D．They are in higher spirits.

To all of you at Chinese love links.
I am 44 years old and never married. I have always wanted to find that perfect someone that I dream about. For about the last five years I have almost given up the hope of ever finding the one I truly wish to spend the rest of my life with.
I have always tried to be a nice guy. I had found your website some four or five months before. I did not know what to expect. I don’t know how to speak Chinese and never thought truly of how I was to an Asian woman.
Well, I had a lot of replies from some very nice and pretty women. I had a hard time finding only a couple to write to. But one stood out from the rest. She was cute, nice and seemed to hold a lot of the same values as I do. In a short time I had decided to write only to her. We communicate via e-mails 2-3 times a day and phone calls once or twice a week.
I went and met her and her family only a week ago. Her name is Yun and she lives in Nanning. I found Nanning to be one of the most beautiful cities I had ever been to. We had even decided to marry and bring her to the USA under the finance visa. Not only did she meet everything I had ever hoped to find in someone else but turned out to be what every woman should be like, at least the ones I have met. We plan to marry as soon as she is here and start a family together as neither of us has children but we both want them.
So to anyone out there reading this, I can only say this: You may not find what you are looking for if you’re not honest with your partner and yourself. This site worked for me mostly because I was honest with something that I wanted in someone else. When I did find her, love can work even across the other side of the world, between language differences and cultural differences. I wish you all luck in finding your perfect match. I have finally found mine and wish to give all my thanks to those at Chinese love links to help make it happen.
Sincerely yours,
Arthur

科目：高中英語(yǔ) 來(lái)源：不詳 題型：閱讀理解

The emperor penguin is the tallest and heaviest of all living penguin species and lives in Antarctica. The male and female are similar in size, reaching 122 cm in height and weighing anywhere from 22 to 45 kg. The back and head are black, contrasting sharply with the pale-yellow breast and bright-yellow ears. Like all penguins, it is flightless, with a streamlined body and their wings stiffen and flatten into flippers(鰭狀肢) for a marine habitat.
Its diet consists primarily of fish, but can also include animals with hard shells. In hunting, the species can remain underwater up to 18 minutes, diving to a depth of 535 m. Its unusually structured hemoglobin(血紅蛋白)allows it to function at low oxygen levels.
The emperor penguin is perhaps best known for the journeys adults make each year in order to mate and to feed their babies. The only penguin species that breeds(繁殖) during the Antarctic winter, it goes on a long journey of 50-120 km over the ice to breeding areas which may include thousands of individuals. The female lays a single egg, which is incubated(孵化)by the male while the female returns to the sea to feed; parents take turns searching for food at sea and caring for their chick. They both care for the chick until it is able to enter the water to find food on its own. During the process of incubation, the male can lose up to 1/3 to 1/2 of his body weight. One of the coolest things about the male is that if the chick comes out its egg before the female returns, the male can actually produce a special liquid to feed the chick. He can only do this for a short time. If the female doesn’t return, he must leave the chick to go on with his own life. The emperor penguin can typically live for 20 years in the wild, although observations suggest that some individual may live to 50 years of age.
小題1:We can learn from paragraph 1 that ____.
A．the emperor penguin is the world’s largest kind of penguin
B．the emperor penguin has pale-yellow ears
C．the male and female emperor penguins are of different sizes
D．the emperor penguin lives in the most northern area on the Earth
小題2:The emperor penguin can stay underwater for a long time mainly because of its ____.
A．strong wingsB．streamlined bodyC．structured hemoglobinD．special diet
小題3:The emperor penguin differs from other penguin species in that ____.
A．it gives birth in the Antarctic winterB．it feeds mainly on fish
C．the male won’t search for food on his ownD．it can only live for a short time
小題4:According to the passage, ____.
A．the egg of the emperor penguin is mainly incubated by the female
B．many emperor penguins will stay together to breed
C．the male emperor penguin will give up his own life to feed the chick
D．the female emperor penguin will leave the chick forever once it lays an egg
