When I met Mr Jim Lemon I was a seventeen-year-old freshman at Houston's Jackson Junior High.The chances of my finishing high school were 36 . I was a troubled teenage.
Mr Lemon taught American history and was quite 37 from the other teachers I had known. Not only was he 38 , but also he was a great teacher. He pushed and never tolerated the mediocrity(平庸) that had become my standard.
On the occasion of our first semester report cards, Mr Lemon 39 me aside and asked how it was possible that I was a B student in his class and a C student in the 40 of my classes. I passionately told him about my 41 parents, the local gangs, the drugs, the fights, the police---all of the evils I had been 42 to. It was then that Mr Lemon 43 explained that the only person 44 for my situation was me. And the only person with the 45 to change my situation was me. He 46 me that I was failing not because I was a failure. He inspired me to become a better student and he 47 my life.
Ten years later I was preparing to graduate from a university when I spoke to him again . 48 I did get him on the phone, I told him that I had been saving money so that I could invite him to come to Hawaii at my 49 to be a part of my graduation.
I'll never forget his 50 . He said,"Who is this again?" I was just one of hundreds of the students whose life he changed 51 he had no idea of his influence.
Mr Lemon never came to my graduation, but his 52 taught me another valuable lesson. His final lesson for me was that we will never know or understand the 53 we have on other people's lives. He taught me that we all have the 54 to effect people's lives for the 55 ... Or for the worse.

Directions: Read the following text and choose the most suitable heading from the list A-F for each paragraph. There is one extra heading which you do not need.?
| A. The engine in your body. B. The location, size and heartbeat of a heart. C. What happens when the heart beats? D. How does your heart work? E. How do we know about the heart? F. What can a doctor tell by feeling your pulse? |
Your heart is located in your chest, a little to your left. This heart of yours, which is about the size of your two fists held together, beats about 90 times a minute. A grown person's heart beats about 60 to 80 times a minute. The heartbeat is not just the same in all persons, and it is not the same in any one person at all times.
When your heart beats, it is pumping blood to all parts of your body. If you could examine your heart closely, you would see that it is really two pumps placed side by side, and working at the same time. Each pump has two parts, the upper part called the auricle (心房), and the lower part called the ventricle (心室). The auricles receive the blood as it comes into them after it has been pumped through the body. The ventricles pump the blood out. The right one pumps the blood to the lungs and the left one pumps the blood to all other parts of the body. At the top and bottom openings of each ventricle are valves (阀门) which make the blood go in only one direction.
Your heart is sometimes called the engine or the motor in your body and sometimes called the pump. It works away, both day and night. First it pumps out some blood, rests for a few seconds, and then it pumps some more. In a normal day, the heart pumps about 2,500 gallons of blood from the auricles and ventricles.
By using a stethoscope to listen to the heart, the doctor can tell whether your heart is beating evenly and whether the valves are closing tightly. The stethoscope makes these sounds so clear that the doctor can hear them easily. The stethoscope has an earpiece that he places on your chest and tubes that he places in his ear. The earpiece carries the sound or your heart's beating along the tubes to the doctor's ears, and it makes the sound seem much louder than it really is. The doctor could listen to your heartbeat by pulling his ear against your chest.
An easy experiment can help you understand what happens when the heart beats. You can do this experiment with a hollow rubber ball. Make a small hole in it, and fill the ball with water through the hole. When you squeeze the ball, you will notice how the water comes out in a spurt each time you squeeze. After each spurt the ball comes back to its round shape again. Something like this happens when your heart beats. The muscles in your heart grow smaller, or contract, and squeeze the blood out of the heart. Each time this happens, we say your heart is beating. Perhaps you have noticed that the doctor places his finger on the pulse in your wrist when you are ill. By doing this he can tell how fast your heart is beating.
