Do you want to live forever? By the year 2050, you might actually get your wish — if you are willing to leave your biological body and live in silicon circuits （半导体电路）. But long before then, perhaps as early as 2010, some measures will begin offering a semblance of immortality （虚拟的永生）.

Researchers are confident that technology will soon be able to track every waking moment of your life. Whatever you see and hear, all that you say and write, can be recorded, analyzed and added to your personal chronicles （履历）. By the 2030, it may be possible to catch your nervous （神经） systems through electrical activities, which would also keep your thoughts and emotions. Researchers at the laboratories of British Telecommunications have given the name of this idea as Soul Catcher.

Small electronic equipment will make preparation for Soul Catcher. It would use a wearable supercomputer, perhaps in a wristwatch, with wireless links to micro sensors under your scalp （头皮） and in the nerves that carry all five sensory signals. So wearing a video camera would no longer be required.

At first, the Soul Catcher’s companion system — the Soul Reader — might have trouble copying your thoughts in complete details. Even in 2030, we may still be struggling to understand how the brain is working inside, so reading your thoughts and understanding your emotions might not be possible. But these signals could be kept for the day when they can be transferred to silicon circuits to revitalize minds everlasting entities （永生实体）. Researchers can only wonder what it will be like to wake up one day and find yourself alive inside a machine.

For people who choose not to live in silicon, semblance of immortality would not be as useless as they thought. People would know their lives would not be forgotten, but would be kept a record of the human race forever. And future generations would have a much fuller understanding of the past. History would not be controlled by just the rich and powerful, Hollywood stars, and a few thinkers in the upper society.

1．The main idea of this passage is that               .

A．human beings long for living forever

C．people can live forever as technology develops

D．the invention of Soul Catcher has great importance

2．According to this passage, a Soul Catcher will be           .

A．a new machine on which research measures have already been made

B．a new invention in order to catch and keep human’s thoughts

C．made by British scientists to offer something that looks like living forever

3．We can infer from the passage that semblance of immortality is            .

A．to be a reality sooner or later                               B．far from certain

C．just an idea that couldn’t t be realized at all           D．a fading hope

4．The meaning of the underlined word “revitalize” in the fourth paragraph is close to             .

A．make dead              B．make famous           C．make known           D．make active

Not all memories are sweet. Some people spend all their lives trying to forget bad experiences .Violence and traffic accidents can leave people with terrible physical and emotional scars . Often they relive (重新体验) these experiences in nightmares .

Now American researchers think they are close to developing a pill ,which will help people forget bad memories . The pill is designed to be taken immediately after a frightening experience . They hope it might reduce , or possible erase (抹去) the effect of painful memories .

In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain . So far the research has suggested that only the emotional effects of memories may be reduced , not that the memories are eased .

The research has caused a great deal of argument . Some think it is a bad idea , while others support it . Supporters say it could lead to pills that prevent or treat soldiers’ troubling memories after war .

They say that there are many people who suffer from terrible memories . “Some memories can ruin people’s lives . They come back to you when you don’t want to have them in a daydream or nightmare . They usually come with very painful emotions ,” said Roger Pitman , a professor of psychiatry (精神病学) at Harvard Medical School. “This could relieve a lot of that suffering .”

But those who are against the research say that changing memories is very dangerous because memories give us our identity (物质). They also help us all avoid the mistakes of the past . “All of us can think of bad events in our lives that were horrible at the time but make us who we are . I’m not sure we’d want to wipe those memories out.” said Rebecca Dresser , a medical ethicist (伦理学家).

Some people fear that although the drug would first be used in only very serious cases , it would become more and more common . “People always have the ability to misuse science,” said Joeph Le Doux, a New York University memory researcher . “All we want to do is help people have better control of memories .”
