Last Friday, as usual I went home by bike. But at a crossing, I 56__________ (sudden) knocked an old man off his bike. I hurried over and found that his leg 57____________ (injure). Nervous and worried, I called my mom and told her what had happened. We decided to take him to the hospital first.

Shortly after we arrived at the hospital, my mother came. I had some doubt 58 ____________ there was anything seriously wrong with the old man. The doctor gave the old man a 59___________ (detail) examination. To our delight and relief, there was nothing seriously wrong with him. We thanked the doctor and left. After that, we went back to the place 60___________ the old man’s bike was parked, only 61_________ (find) it didn’t work. So I immediately found a repairman to get it 62_________(fix). Soon he finished 63_________ (repair) it. Before the old man left, my mom offered him our cell phone number in case he needed to contact us. Then the old man got on his bike and we waved goodbye to each other.

If I 64__________(ride) my bike carefully, I would have avoided the accident. Consequently, the unexpected accident made me realize that in the first place we should be careful, but once it occurs, we should take 65______________ (responsible).

After graduating from college, I became a reporter and was asked to inspect a/an    （5） (legal) business. My report had helped people and also helped the government catch the guilty people. That was the special moment （7）    I realized the importance of being a journalist.      （6）_____(write) the report was not esay, but I didn’t give up. As you can see, my efforts paid off. So as long as I   （8）   (commit), I will produce high quality reports. Actually, although there isn’t much glory in a reporter’s  （9）   (exist), I find it intersting and challenging because I am   （10） (constant) challenged to learn new skills, go to different places and meet lots of people. And I am always curious, for what I have learnt from my mom has never left me.

In a town in the south of France, twenty poor people were served with dinner, at          certain hour every day. A dog          (belong) to the place was always present at this meal, to eat the leftover food       (throw) to him every now and then.

The guests, however, were poor and hungry, and of course not very generous. So the poor dog hardly did more than smell the feast, of       he would have liked a share.

          happened that this dinner was served out to each one who rang a bell, but, as the person who served the dinner handed it through a small opening, he did not see 62（1）.            received it.

Well, one day the dog （2）       (wait) till all the poor people were gone.

（3）     (get) very little to eat, he reached up, took hold of the rope by his teeth, and rang the bell. A good dinner was at once handed out, and the dog ate it （4）      great delight.

This was done by the dog for several days; the truth was （5）        (final) found out. However, people thought the dog was so clever that he was allowed to take his regular turn at the dinner every day.

Educated people in the twenty-first century may find it hard to believe that two hundred years ago people did not link illness   61   environmental problems. We all know that in London drinking  62   (pollute) water caused many deaths from cholera. So many thousands of people became  63   (terrify) every time there was an outbreak. John Snow was interested in its cause. First he marked on a map the exact places   64   all the dead people had lived. John’s investigation proved the dirtier the water,    65   (severe) the illness. He drew a  66   (conclude) that many of the deaths were near the water pump in Broad Street and cholera wasn’t spread in   67   cloud of gas . He   68   (immediate) told people to remove the handle from the pump. To prevent this from   69   (happen) again, John Snow suggested that the source of all water supplies be examined. Thus cholera   70   (defeat) in the end.
