The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep colour in meats and other food additives（添加剂）caused cancer.

Yet, these additives remain in our food, and it is difficult to know which things on the wrappings（包装）of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar tings are supplied to animals not for their health, but just to make a profit.

The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.

Our plan was to drive into Cambridge, catch the 7:34 train to Liverpool Street Station, then to separate and meet again for lunch．We should have arrived at Liverpool at 9:19, but due to a typical London fog, the train had to move along so slowly that it wasn’t until 10:30 that it got there．In spite of our late arrival, Joan, my wife’s sister, decided that she would go to see the Crown Jewels in the Tower of London while we went shopping．It was only after her sister had disappeared into the fog that my wife realized that we hadn’t decided where we should meet for lunch．Since I had our three tickets for the concert in my pocket, this was indeed a problem．There seemed to be nothing we could do except taking a taxi to the Tower of London, and try to find her there．Needless to say, we didn’t find her.
It was now one o’clock, and the concert began at 2:30．“Perhaps she will think of waiting outside the concert hall,” suggested my wife hopefully．By this time the fog was so thick that road traffic had to stop, and the only way to get there was by underground railway．Hand in hand we felt our way along the road to where we thought the nearest station should be．An hour later we were still trying to find it．Just as I was about to lose my temper completely when we met a blind man tapping his way confidently through the fog．With his help we found Tower Hill tube station just fifty yards down the road.
By now it was far too late even to try to get to the concert hall before the performance began at 2:30, so we decided to return to Cambridge．It took seven long hours instead of the usual two to make that journey．Nor were we able to get any food and drink on the train．Tired and hungry we finally reached home at ten, opening the door to the sound of the telephone bell．It was Joan; she had seen the Crown Jewels, had managed to get another ticket for concert, and had had a wonderful dinner at a restaurant near the hotel where she decided to stay for the night．Now she was ringing to discover whether we had had an equally successful day.
1．Why was Joan separated from her sister and her brother-in-law?
A．they could not see each other because of the fog.
B．Joan had not seen Crown Jewels.
C．They planned to do different things until lunch time.
D．The writer didn’t want to go to the concert.
2．What did the writer plan to do in the afternoon?
A．Go to the concert.                      B．See the Crown Jewels.
C．Return to Cambridge.                    D．Go shopping.
3．The reason why they didn’t all meet for lunch was that _______.
A．They lost their way in the fog
B．they forgot to make necessary arrangement
C．they waited at different places and didn’t meet each other
D．the couple couldn’t find the underground station
4．It’s quite clear that for Joan the trip to London had been ________.
A．spilt by the fog                      B．quite tiring  
C．rather disappointing               D．very enjoyable

Though I have traveled in hundreds of trains, few unusual things have ever happened to me. But one day in a train something did happen. I do not mean that I was hurt: no one was hurt.

I do my work in a hot country far away from England. Every September I go there to do my business, and every July I come back to England to have a rest. So every September I go to Paris and take a train from the great French city to Mendova, and at Mendova I catch my ship.

There is one very fast train from Paris to Mendova, and it suits me well. It goes as far as Endoran, but it stops at Mendova for a few minutes to let travelers get out or in. It is called The Flying Bluebird. It reaches Mendova at seven minutes past nine in the morning, and it is never late.

A ship leaves Mendova at half past eleven, and so you will understand that The Flying Bluebird suits me very well. I always travel by it, and I have nearly two and a half hours at Mendova to go from the station to the ship. That is more than enough time.

Well, one September night, I took my place in The Flying Bluebird as usual. The train leaves Paris at nine o’clock every night, and I was in my place soon after half past eight. There were three or four people there with me, but very soon a lot of others got into the train. When no more people could sit down, they began to stand up near us and also in the corridor（走廊）. In a short time the corridor was full too, and it was impossible for any more travelers to get into the train.

I could see a lot of other people outside the corridor windows, but they could not get in, and the train left Paris without them. The man sitting next to me started to ask all kinds of questions: “Where do you work? How long does it take you to get there? Are you married? How many children do you have? How much money do they pay you every year? How much do you have in the bank? How much do you spend every month?”

He asked questions for about twenty minutes but I did not give him any clear answers, and at last he stopped and began to read the paper.

I usually sleep quite well in the train, but this time I slept only a little. There were too many people, and there were too many things: small bags, large bags, coats, hats, boxes, newspapers and food. As usual, we got angry about the window. Most people wanted it shut, and two of us wanted it open. But that always happens. It was shut all night, as usual.

When I awoke in the early morning I felt hot and dirty, and glad that the journey was reaching its end. At seven minutes past nine The Flying Bluebird stopped. We were at Mendova, and I stood up thankfully. I took my two suitcases, held one in each hand, and tried to move towards the door into the corridor. In order to get out of the train, I had to pass down the corridor to the door at the far end. There was no other way out.

I could not even into the corridor. There was a suitcase on the floor by my feet, and three men were standing in my way. I felt a touch of fear. I had to get out, you see; I had to catch my ship, which left at half past eleven. And the train did not stop again until it reached Endoran, two hundred miles away.

“I must get out!” I cried. Everyone there understood me, but no one could move.

At last I was able to put one foot over the suitcase on the floor, and I nearly reached the door into the corridor. But then, very slowly, the train began to move. It was taking me away!

“Stop!” I cried. “I want to get out!” But no one outside the train could hear me, and the people inside did not care much. The train moved a little faster. What could I do? I was not even in the corridor.

Fear made me think quickly. In front of my eyes, just, above the door, was a notice that told everyone how to stop the train. I had to pull an iron thing near the notice. I did not waste time. I pulled it.

Well, a noise started above our heads. That was to show everyone that there was something wrong. It was not a small sound. Possibly the men in my ship two miles away could hear it. Then the train stopped.

No one likes to stop a train if there is no need. But I had to catch my ship. That was the only thought in my mind: to get out and catch my ship.

Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.

     Perhaps the best answer lies in our genetic makeup(基因构成) as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.

Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.

    Exploration also allows minerals and other potential resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products (副产品) of technological developments in the space industry!

While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The danger exists, but knowledge can help human beings to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.

While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.
