What will you be doing when you are 26 years old? Studying at university or working for a living? Take a look at what Albert Einstein was doing at the age of 26.
100 years ago, Einstein was working in Switzerland. His hobby was physics. Without much money or help, he wrote five papers(论文) for a physics magazine. Three of these greatly changed the study of physics and our understanding of space, time, light and matter(物质). His most famous work is on the Theory of Relativity(相对论). Einstein was given the Nobel Prize for his discoveries. Although he also did many other things later, the years 1905 has been called Einstein’s “Year of Wonders”. It has been 100 years since then. Because of this, the UN has named 05 the World Year of Physics.
Today, over fifty years after Einstein’s death, a question is asked, “ Will there ever be another Einstein?” It may take a long time. After all, Einstein was born more than 200 years after Sir Isaac Newton, another great scientist. Besides, physics is a different field now, and education is different, too. Even if you can’t be the next great scientist, it is still helpful to remember some of the things that made Einstein great. He thought independently(独立地) and read widely. He left with us a formula(公式) for life: If A is a success in life, then A="X+Y+Z." X is work, Y is play, and Z is keeping your mouth shut.
【小题1】The year 1905 is known as Einstein’s “Year of Wonders” because .

A．Einstein was working in Switzerland in 1905	B．Einstein was 26 years old in 1905
C．Einstein made some very important discoveries in 1905	D．Einstein studied physics in 1905

【小题2】Why hasn’t there been another scientist as great as Einstein?

A．Because the study of physics is not enough.

B．Because it is hard to make important discoveries as Einstein did.

C．Because people don’t work hard any more.

D．Because physics is getting more and more difficult.

【小题3】The UN has named 05 the World Year of Physics because .

A．Einstein is 100 years old this year

B．Einstein has been dead for more than 50 years

C．there have been other great discoveries after Einstein’s death

D．it is the 100^th year since Einstein’s “Year of Wonders”

【小题4】 What does Einstein’s formula for life mean?

A．Success means years of hard work.

B．Success means all study and no play.

C．Success means working hard, relaxing and not talking too much.

D．Success is a secret that nobody knows.

--- Why hasn’t Jenny turned up?

--- Oh! She called me just now and said that she was _____ the way.

A. by B. in C. at D. on

In the future your automobile（汽车） will run on water instead of gas! You will be able to buy a supercomputer that fits in your pocket! You might even drive a flying car!

For each prediction that has come true today, several others have missed by a mile. Many of these predictions didn’t consider how people would want to use the technology, or if people really needed it in their lives or not. Let’s look at some predictions from the not-too-distant past.

Robot Helpers

Where’s the robot in my kitchen? Nowhere, of course. And he’s probably not coming anytime soon. Robots do exist today, but mostly in factories and other manufacturing environments.

Back in the 1950s, however, people said that by now personal robots would be in most people’s homes.

So why hasn’t it happened? Probably because robots are still too expensive and clumsy. And maybe the idea of robots cooking our dinners and washing our clothes is just too weird. At home we seem to be doing fine without them.

Telephones of Tomorrow

In 1964 an American company introduced the video telephone. They said by the year 2000 most people would have a video phone in their homes. But of course the idea hasn’t caught on yet.

Why? The technology worked fine, but it over—looked something obvious: people’s desire for privacy（隐私）. Would you want to have a video phone conversation with someone after you just step out of the shower（淋浴）? Probably not---it could be embarrassing! Just because a technology available doesn’t always mean people will want to use it.

And finally, how about that crazy prediction of the flying car? It’s not so crazy anymore! But a flying car remains one of the most fascinating technology ideas to capture our imagination. Keep watching the news, or perhaps the sky outside your window, to see what the future will bring.

The whole passage is mainly about ________________.

A. predictions that have come true. B. predictions that haven’t come true.

C. why predictions don’t come true easily. D. what technology will bring about.

The author of this passage won’t believe that _________________.

A. predictions needn’t consider people’s practical use of technology.

B. the future isn’t always easy to guess.

C. not all past predictions have come true.

D. many of the high—tech things our parents thought we’d be using by now

simply never appeared.

The underlined word “weird” probably means __________.

A. wonderful B. stupid C. practical D. strange

What does the author think of the flying car?

A. It is too difficult to imagine. B. It is too crazy an idea.

C. It is likely to be made. D. It is often reported in the news.

Stuck on a desert island?
Started on 23rd April by Steve Posts 1--7 of 42
Post 1 Steve USA	Hi, everyone. What would you miss most and least if you were stuck on a desert island? For me, it would be the changing seasons in New England. I guess this will sound stupid but I’d probably miss the rain, too. I wouldn’t miss getting up at six every day to go to work, though! What about you?
Post 2 Tomas Germany	Good question, Steve. I think I’d miss different types of bread, and shopping at the supermarket. I’d miss the food most. What would I miss least? My mobile phone--I’d like to be completely quiet--at least for a little while.
Post 3 Paola Italy	I would miss the company of people because I know I’d like to have someone to share experiences with. I’d go mad on my own. And I sure wouldn’t miss junk mail(垃圾邮件)--I hate coming home every evening and finding a pile of junk mail in my post box.
Post 4 Miko Japan	Hi, I would miss Manga cartoon, the Internet and Japanese food, like sushi. I’d also miss TV shows and shopping for clothes…In fact, I’d miss everything.
Post 5 Roger UK	I would miss my daily newspaper and listening to the news on TV and radio. I’d feel very cut off if I didn’t know what was happening in the world. What I’d miss least would be traffic jams in the city, particularly my journey to work.
Post 6 Jayne Canada	Why hasn’t anyone mentioned their family? I’d be lost without my husband and two kids. They are the most important for me. And I can’t get started in the morning without a cup of black coffee. I wouldn’t miss doing the housework.
Post 7 Jaime Mexico	It would have to be music．I couldn’t live without my music．I wouldn’t miss going to school at all or doing homework!
