I love science and science fiction. Like many...

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.

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?

2.What’s the meaning of the underlined word “illusion”?

A. success          B. dream                C. switch               D. support

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.

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

When I was a kid, I loved reading history, science fiction, detective stories, but especially comics. I had piles of them and kept talking my Dad into making more shelves for me. One day, I read about a 13-year-old boy who had actually written one of my favorite comics, Legion of Super-Heroes, and I said, “I can do that too.” That year, I was two years younger than the writer.

Three years later, a friend and I started our own fan magazine about comics. It became the first place that regularly told people when their favorite comics were coming out and writers and artists were working on them. Because of the magazine, I won the awards for The Comic Reader, but more important, it got many of the people in the field to know who I was.

One day when I was visiting DC Comics for news for my next issue, one of the editors a chance to write text for his comic. Suddenly, at 16, I was getting paid to write.

I was able to pay for my college classes working as an assistant editor at DC Comics and learned how to write comics stories while I was there. I wrote hundreds of stories. Over the years, I worked as an editor and an executive (主管) for the company, eventually serving as a president and publisher, until earlier this year. Now I’m back to my first love, writing comics again.

Every morning, I open my e-mail and find pages of art sent in by artists across the country who draw my stories. When I’m tired of working on the stories, I can go online and find my readers commenting on my stories or telling me when I make mistakes.

Keep reading and writing, it’s a wonderful way to live.

Many science fiction stories tell about explorers arriving in a new world. The explorers then use some kind of high-tech device to test for breathable air or signs of life. But here on Earth, science fiction is becoming reality through a new sampling technology called environmental DNA, or eDNA for short. Scientists can use it to identify rare species or estimate fish populations with just a little air or water.

Environmental DNA can be used in two ways. One is to identify the creatures that live in a certain place. The other is to confirm the presence or lack of a specific creature.

Caren Goldberg is one of the first biologists to take the technology from the testing stage to actually using it. She sees eDNA as a way to get answers more efficiently and with less destruction compared to traditional survey techniques. Until recently, scientists depended on snorkeling ( 潜水), netting or using an electric current to temporarily catch fish.

This newer way to identify what lives in the environment is becoming popular around the world. Animal experts in Vietnam are using the eDNA to find the last, wild Yangtze giant softshell turtles. One researcher on the Caribbean island of Trinidad is using the sampling technology to find endangered golden treefrogs. In Madagascar, it is being used to identify amphibian(两栖动物)diseases.

Ms Goldberg has used eDNA testing to confirm the local extinction (灭绝) of a leopard frog in the American state of Idaho. She has also been asked to document the spread of the New Zealand mudsnail in the state of Washington. The creature has been found in lakes and other waterways across the state.

Scientists working with the technology say they do not expect robots to replace field biologists anytime soon. But the old-fashioned field work could soon be more targeted.

1.Compared to traditional survey techniques, eDNA is more______.

A. complex　　 B. eco-friendly

C. dangerous　　 D. convincing

2.By using eDNA, Caren Goldberg has______.

A. succeeded in catching many fishes

B. found the existence of golden treefrogs

C. documented the spread of softshell turtles

D. confirmed the disappearance of the leopard frog in Idaho

3.What can we infer from the last paragraph ?

A. Robots will replace scientists soon.

B. Some scientists are against using eDNA.

C. The old-fashioned field work may disappear.

D. Many biologists are unwilling to do the field work.

4.What is the best title for the text?

A. Science Fiction Becomes Reality for Species Surveys

B. Biologists Explore Space with the Help of eDNA

C. Scientists Found Methods to Test for Signs of Life

D. New Technologies Are Presented in Science Fictions

Since his early childhood, G. A. Minton has always been a faithful fan of science fiction and horror. Whenever a scary movie was playing at the local theatre, he was there in attendance with his friends, loudly screaming in terror.

In his everyday life, Minton likes playing the game of golf most, having lettered on his high school golf team. In addition to writing, he also enjoys reading, traveling, fishing, swimming, working out, listening to hard rock music, and watching great movies－especially those about horror, science fiction, mystery and comedy.

Strangely enough, it was only after Minton was knocked down by a drunk driver and suffered a closed-head injury that he developed a new found passion for writing.

At the end of the healing process, something was very different. He noticed that he had developed a strong urge to write down a story that had formed in his mind. That’s how his first novel Trisomy XXI was born. He penned（写作）it in only three months. He began with chapter one and wrote in a freestyle manner—almost in a stream of consciousness. The narrative flowed freely from his vivid imagination, creating a thrilling tale of terror that is formed from an ordered sequence of events.

One could think that the damaged neurons（神经元）had rearranged themselves into a different pattern, and thus improving the creative elements in his brain. Besides, stranger things have happened! He has recently completed his second novel. Currently, his brain is busy at work, seriously processing the text for another -story of the terror-one that will both entertain and horrify its unsuspecting reader!

The TV science-fiction series Star Trek no longer looked far-fetched (牵强的) as four men and four women in black space-suits locked themselves into a giant hi-tech greenhouse, known as a ‘biosphere’, in the Arizona desert yesterday for a two-year study of the environment.

As dawn broke over the Santa Catalina mountains, the eight waved goodbye to television cameras. Edward Ross, their multibillionaire sponsor from a Texas oil family, closed the door of the $150 million structure, with its mini-ocean, marsh, desert, savanna, rain-forest and 3,800 plant and animal species designed to allow the team to recreate Earth and its ecosystems.

The so-called Biosphere 2 is the latest of a dozen environmental projects started by the self-titled ‘ecopreneur’. The project’s main aim is to set up a self-sustaining community for possible use in a spaceship or on another planet. The crew members must plant, harvest and process their food on a half-acre farm in the seven-storey glass and metal structure, while conducting a series of experiments.

‘We will be custodians (监护人) of our new little world,’ said Abigail Mayer, aged 31, a US marine biologist on the team, her voice choking with emotion. ‘It is a brave new step.’ Many scientists, however, are more than skeptical. They point out that the largest closed ecosystem which survived more than a few days was smaller than a football. It was developed at the University of Miami and contained only shrimp, algae and other micro-organisms.

Critics have also accused Mr. Ross of being more interested in producing a profitable theme park than in carrying out serious scientific research. Hundreds of tourists visited the site daily in the summer before it was occupied by the team. They paid $9.95 to enter and all stopped at the souvenir shop.

1.What’s the location of the project?

A. Texas.

B. University of Miami.

C. Arizona desert.

D. The space.

2.What can we infer from the passage?

A. There is a scene in Star Trek where four men and four women locked themselves into giant greenhouse.

B. All the species of plants and animals on the Earth were brought into the greenhouse.

C. Mr. Ross made tourists stop at the souvenir shop to gain profits.

D. Many scientists are doubtful whether this system can last long enough.

3.What’s the author’s attitude towards the project?

A. Critical.        B. Neutral.        C. Skeptical.        D. Supportive.

Vegetable gardening is the relaxing art and science of turning a love for growing plants into a worthwhile activity.

Vegetable gardeners agree that many home-grown vegetables picked at their best are superior to those vegetables purchased from markets. From spring through late fall, a well-planned and well-kept garden can prove a supply of fresh vegetables, thus increasing the nutrition of the family diet. Freezers make it possible to keep some of the vegetables to be enjoyed at a later date. Other vegetables can be stored for a few months in a cool area.

Having vegetables in the backyard makes home gardening appealing(吸收人的) for many people. In addition, vegetable gardening provides exercise and fun for both urban and suburban families.

Although the money spent for a garden may be little, one cannot escape the fact that gardening requires hard work and time. Many of the gardening tasks must be performed at times that are most inconvenient. Not doing jobs that should be done on a regular basis may result in failure and a negative feeling toward gardening.

One should not plant a garden that is too large for him to care for. A small, well-kept garden is more enjoyable and profitable than a large neglected one. Vegetables do well in full sunlight and need at least five or six hours of sun during the middle of the day. Too much shading results in poor plants and few vegetables. If possible, the garden should be near the house so the gardener can work in it at odd moments.

Soils for vegetables should be easily broken up and porous(能渗透的) for quick water drainage and good aeration(透气). A deep, fine, sandy good quality soil is best.

Usually the hoe owner has little choice in the soil type he can choose. Fortunately, many vegetables can be grown on poor soils if the soils are properly prepared.

1.Home-grown vegetables ___________.

2.Vegetables gardening is appealing for many people because ___________.

3.The author suggests that an ideal vegetable garden ___________.

4.Which of the following would be the best title for this passage?
