It is hard to predict how science is going to turn out , and if it is really good science, it is impossible to predict. If the things to be found are actually new, they must be unknown in advance You cannot make choices on this matter. You either have science or you don't and if you have it you have to accept the surprising and disturbing pieces of information, along with the neat and useful bits.

The only solid piece of scientific truth about which I feel totally confident is that we don’t know enough about nature. Indeed, I regard this as the major discovery of the past hundred years of biology. It is, in its way, a clear piece of news. It would have amazed the brightest minds of the 18th century to be told by any of us how little we know and how strange seems the way ahead . In earlier times, they either pretended to understand how things worked or simply made up stones to give answers. Now that we have begun exploring seriously, we are catching sight of how huge the questions are, and how far from being answered. Because of this, we are sorry. It is not so bad being ignorant     if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted.

But we are making a beginning, and there ought to he some satisfaction. There are probably no questions we can think up that can’t he answered, sooner or later. Within our limits, we should be able to work our way through to all our answers, if we keep at it long enough, arid pay attention.

It was about midday. I’d left work early in the morning to cash a cheque. I walked along to the bank, and found that there weren’t too many people about ten or eleven customers in there, which was pretty unusual for those central city banks.

    I waited until it was my turn and just went up to the desk and started to talk to the bank clerk. He had a really strange expression on his face -- just sort of blank stare at least I thought he was looking at me and then I realized he was staring over my shoulder.

    I began to turn round to see what he was looking at. At the same moment the outside bank guard came flying through the door and lay face down on the floor and following him through the door were three frightening masked men. They were carrying guns; at least I think the one in front was carrying a gun. Whether or not they said anything at that point I can’t remember to this day, or whether people just automatically put their hands up I’ve just no idea.

    For a few moments there was just total silence, suddenly broken by the telephone ringing and I remember thinking and wondering who was on the other end of the telephone. Nobody went to answer the telephone, so this thing just kept on ringing and ringing. Then two of the masked men went to the counter, jumped over it and got the cashiers and the bank clerks to start filling the bags with cash. While the two were getting the money, the one at the door who was covering us with the gun was a bit frightened. He started swearing at them, and telling them to hurry up, to get a move on. They jumped back over the counter. One of them slipped as he landed on the floor and fell over and the other two swore at him again. They left through the door. Warning us, “Don’t move, stay like that with your hands up for ten minutes.” And then they just disappeared. Again back to total silence. People put their hands down, I put my hands down but I just stayed exactly where I was.

    A. More customers than usual were staying in the bank.

    B. Less bank clerks than expected were in the bank.

    C. There were often more than a dozen customers in the bank.

    D. More banks should be open to serve customers in the city center.

The bank clerk wore a blank expression on his face probably because ________.

    A. he was feeling upset at that moment

    B. he felt puzzled and sensed something terrible

    C. he was required to keep silence

    D. he was threatened with a gun by robbers

Which of the following is true according to the passage?

    A. The customers didn’t wait in line but jumped the queue because of the confusion.

    B. All the people in the bank except the writer put their hands up automatically.

    C. Nobody answered the phone because all the clerks were busy with work.

    D. the bank workers were forced to fill the robbers’ bags with cash.

What’s the best title of this passage?

【小题1】What does the writer mean by saying “…a pretty unusual number for those central banks” in the first paragraph?

It was Saturday . As always, it was a busy one, for “Six days shall you labor and do all your work” was taken seriously back then. Outside,Father and Mr. Patrick next door were busy chopping firewood. Inside their own houses, Mother and Mrs. Patrick  were engaged in spring cleaning.
Somehow the boys had slipped away to the back lot with their kites. Now, even at the risk of having Brother caught to beat carpets , they had sent him to the  kitchen for string(线). It seemed there was no limit to the heights to which kites would  fly today.
My mother looked at the sitting room ,its furniture disorderd for a thorough sweeping, Agun she cast a look toward the window. “Come on, girls ! Let’s take string to the boys and watch them
On the way we met Mrs. Patrick, laughing guiltily as if she were doing something
wrong, together with her girls.
There never was such a day for flying kited! We played all our fresh string into  the boys’ kites and they went up higher and higher .We could hardly distinguish   the orange-colored spots of the kites. Now and then we slowly pulled one kite back, watching it dancing up and down it the wind, and finally bringing it down to earth , just for the joy of sending it up again.
Even our fathers dropped their tools and joined us. Our mothers took their turn, laughing like schoolgirls. I think we were all beside ourselves. Parents forgot their  duty and their dignity; children forgot their everyday fights and little jealousies. “Perhaps it’s like this in the kingdom of heaven,”  I thought confusedly.
It was growing dark before we all walked sleepily back to house. I suppose we   had some sort of supper. I suppose there must have been a surface tidying-up, for the house on Sunday looked clean and orderly enough. The strange thing was , we didn't mention that day afterward. I flt a little embarrassed .Surely none of the others had been as excited as I. I locked the memory up in that deepest part of me where we  keep“the things that cannot be and yet they are.”
The years went on, then one day I was hurrying about my kitchen in a city  apartment, trying to get some work out of the way while my three-year-old insistently  cried her desire to “go park ,see duck.”
“I can’t go!”  I said. “I have this and this to do, and when I’m through I’ll be too  tired to walk that for.”
My mother , who was visiting us , looked up from the peas she was shelling ,“It’s a wonderful day,”she offered，“Really warm , yet there’s a fine breczc . Do you  remember that day we flew kites?”
I stopped in my dash between stove and sink . The looked door flew open and  with it a rush of memories. “Come on.”I told my little girl. “You’re right , it’s too  good a day to miss.”
Another decade passed. We were in the aftermath (余波)of a great war. All evening we had been asking our returned soldier, the youngest Patrick Boy, about  his experiences as a prisoner of war. He had talked freely , but now for a long time  he had been silent . What was he thinking of – what dark and horrible things?
“Say!” A smile slipped out from his lips . “Do you remember --- no, of course  you wouldn’t . It probably didn’t make the impression on you as it did on me.”
I hardly dared speak.“Remember what ?”
“I used to think of that day a lot in POW camp(战俘营), when things weren’t too  good. Do you remember the day we flew the kites?”
