Why hasn’t he come?________ on time, we would have to put off the trip.


  1. A.
    If he doesn’t come
  2. B.
    If he will not come
  3. C.
    If he didn’t come
  4. D.
    If he wouldn’t come
C
試題分析：句意為：他為什么還沒來？如果他不來的話，我們就只好將旅行的時間往后延。
If引導(dǎo)的虛擬語氣，如果從句為現(xiàn)在時，則使用虛擬語氣時用一般過去式；如果從句為過去式，則使用虛擬語氣時用過去完成時；如果從句為將來時，則使用虛擬語氣時用一般過去式或should+動詞原形/were+ to do .根據(jù)主將從現(xiàn)的原理，if引導(dǎo)的真實條件句為現(xiàn)在時，則從句用虛擬語氣時用一般過去式，故選C
考點(diǎn):考察if引導(dǎo)狀語從句的用法
點(diǎn)評：if引導(dǎo)的虛擬條件從句一直是考察的重點(diǎn)，考生在作答作答時，一定要認(rèn)真區(qū)分if引導(dǎo)的是真實還是非真實條件狀語從句，從而正確判斷。

  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(論文) for a physics magazine. Three of these greatly changed the study of physics and our understanding of space, time, light and matter(物質(zhì)). His most famous work is on the Theory of Relativity(相對論). 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(獨(dú)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.
【小題1】The year 1905 is known as Einstein’s “Year of Wonders” because           .

A．Einstein was working in Switzerland in 1905B．Einstein was 26 years old in 1905
C．Einstein made some very important discoveries in 1905D．Einstein studied physics in 1905
【小題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.
【小題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 100th year since Einstein’s “Year of Wonders”
【小題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.

In the future your automobile（汽車） 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（隱私）. Would you want to have a video phone conversation with someone after you just step out of the shower（淋�。�?  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.

1.

 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.

2.

 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.

3.

The underlined word “weird” probably means __________.

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

4.

 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(垃圾郵件)--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.

Jaime

Mexico
