Science Fiction

1. Among the most popular books being written today are those that are usually classified(分类) as science fiction. Hundreds of titles are published every year and are read by all kinds of people. Furthermore, some of the most successful films of recent years have been based on science fiction stories.

2. It is often thought that science fiction is a fairly new development in literature, but its ancestors (先驱)can be found in books written hundreds of years ago. These books were often concerned with the presentation of some forms of ideal society, a theme that is still often found in modern stories.

3. Most of the classics of science fiction, however, have been written within the last hundred years. Books by writers such as Jules Verne and H. G. Wells, to mention just two well-known authors, have been translated into many languages.

4. Modern science fiction writers don't write about men from Mars(火星) or space adventure stories. They are more interested in predicting the results of technical developments on society and the human mind ; or in imagining future worlds that are a reflection of the world that we live in now. Because of this their writing has obvious political undertones (涵义).

5. In an age where science fact frequently overtakes (超过)science fiction, the writers may find it difficult to keep ahead of scientific advances. Those who are sufficiently clear-sighted to see the way we are going, however, may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology.

A. Fairly New Development

B. Classics of Science Fiction

C. Difficulty in Keeping ahead of Scientific Advances

D. Origins of Science Fiction

E. Themes of Modern Science Fiction

Trade Unions

1．Some scholars have associated trade unions with the medieval craft guilds(中世纪的行会), but there are important differences between the two. The guild members were master craftsmen who owned capital and often employed workers. Unions are known as associations of workers with similar skills.

2．In the past, individual workers had no control over the conditions of their working lives; political and economic power was concentrated in the hands of wealthy business owners. Workers found, however, that there was strength in uniting. From their earliest years, union objectives have been higher wages and improved working conditions.

3．Employers resisted, of course. They made great efforts to stop union organizing its activities. Union members were fired, workers were forced to sign contracts in which they promised not to join a union, and companies hired strikebreakers (破坏罢工者) and even gunmen to frighten organizers.

4．One of the earliest successful labor organizations in the United States was the Knights of Labor, founded in 1869. The Knights, which included both skilled and unskilled workers, attempted to organize all workers into one great union. After it successfully struck the Wabash railroad owned by Jay Gould in 1885, its popularity and power grew dramatically. In 1886 the Knights had 700,000 members.

5．The decline of the Knights of Labor, however, came quickly. The strike against Gould was gradually broken, and the Knights' radical positions on social issues cost them public support. In the end, a lack of unity as well as the rapid inflow of unskilled immigrants weakened the union's economic power, and the organization came to an end.

A．Management's Reaction to the Labor Movement

B．The Decline of an Early Union

C．Reasons for Starting a Union

D．Comparison between the Unions and the Medieval Craft Guilds

E．Foundation

F．The Development of an Early Union

Intelligent Machines

1．Medical scientists are already putting computer chips(芯片)directly into the brain to help people who have Parkinson&39;s disease，but in what other ways might computer technology be able to help us？ RayKurzweil is author of the successful book The Age of Intelligent Machines and is one of the world&39;s best computer research scientists．He is researching the possibilities．

2．Kurzweil gets computers to recognize voices．An example of this is Ramona，the virtual(虚拟的) hostess of Kurzweil&39;s homepage，who is programmed to understand what you say．Visitors to the site can have their conversations with her，and Ramona also dances and sings．

3．Kurzweil uses this technology to help people with physical disabilities．One of his ideas is a“seeing machine”．This will be“like a friend that could describe what is going on in the visible world”，he explains．Blind people will use a visual sensor(探测器)which will probably be built into a pair of sunglasses．This sensor will describe to the person everything it sees．

4．Another idea，which is likely to help deaf people，is the“listening machine”．This invention will recognize millions of words and understand any speaker．The listening machine will also be able to translate into other languages，80 even people without hearing problems are likely to be interested in using it．

5．But it is not just about helping people with disabilities．Looking further into the future，Kurzweil sees a time when we will be able to download our entire consciousness onto a computer．This technology probably won&39;t be ready for at least 50 years，but when it arrives，it means our minds will be able to live forever．

Organ Donation and Transplantation

1. Organ donation (捐献) and transplantation (移植) refers to the process by which organs or tissues from one person are put into another person's body.

2. The number of people needing a transplant continues to rise faster than the number of donors. A- bout 3,700 transplant candidates are added to the national waiting list each month. Each day, about 77 people receive organ transplants. However, 18 people die each day waiting for transplants that can't take place because of the shortage of donated organs.

3. There are no age limits on who can donate. Newborns as well as senior citizens have been organ donors. If you are under age 18, you must have a parent's or guardian's consent (同意). If you are 18 years or older, you can show you want to be an organ and tissue donor by signing a donor card.

4. Many people think that if they agree to donate their organs, the doctor or the emergency room staff won't work as hard to save their life. This is not true. The transplant team is completely separate from the medical staff working to save your life. The transplant team does not become involved with you until doctors have determined that all possible efforts to save your life have failed.

5. If you need an organ transplant, your doctor will help you get on the national waiting list. Your name will be added to a pool of names. When an organ donor becomes available, all the patients in the pool are compared to that donor. Factors such as blood and tissue type, size of the organ, medical urgency (紧急) of the patient's illness, time already spent on the waiting list, and distance between donor and recipient (授受者) are considered.

A. Quality of donated organs

B. Benefits of organ donation

C. Distribution of donated organs

D. Quality of donor medical care

E. Age limits for organ donation

F. Status of organ donation and transplantation
