My First Chemistry Teacher英語四級作文

My First Chemistry Teacher

I will never forget my first chemistry teacher. He was a little man with thick glasses, but he had a strange way of making his classes lively and interesting. And his lessons were not easily forgotten.

I still remember one of my lessons from this teacher. After the students were all in the lab, the teacher brought out three bott[es. One was filled with petrol, one with castor oil and one with vinegar. "Now watch carefully," said the teacher.

He then filled a cup with some of the petrol, some of the castor oil and some of the vinegar. As the students watched him quiet[y, he mixed the three together. After that, he held up one of his fingers and showed it to the class. He then dipped it into the cup. After a few seconds he took his finger out. "Now watch," he said. "Remember, you must do every thing as I do."

He put a finger in his mouth, tasted it and smiled, looking rather pleased. Then he handed the cup around the class of students. Each student dipped a finger into the mixture and sucked it. Instead of smiling, each of them made a face. The mixture tasted terrible.

When the cup was at last returned to the teacher, he said sadly, "I＇ m sorry, none of you watched carefully enough. Yes, I sucked a finger, but the finger I put into my muth was not the one I had dipped into the cup."

It was my first important lesson as a student of chemistry and I never forgot it.

我的第一位化學老師

我永遠也不會忘記我第一位化學老師。他戴着一副深度眼境，個頭不高。他有着奇妙的'教學方法，能使他的課上得生動有趣。因此，他的課是不容易忘記的。

我現在還仍然記得他給我們上的一節課。在學生全都進入化學實驗室後，老師拿出三個瓶子。一個瓶子裝滿汽油，一個裝滿篦麻油，還有一個裝着醋。老師説：“現在請仔細觀察。”

於是他拿山一個杯子，裝上一點汽油，一點篦麻油和一點醋。當學生們靜靜地瞅着他時，他把這二種液體攪和在一起。隨後他舉起一個手指給學生看，接着把手指伸到杯子裏蘸了蘸。幾秒鐘後他把手指拿出來，説：“現在大家瞧着。記住，你們都要照我這樣做。”

他把一個手指放進嘴裏，嚐了嚐，微笑着，顯出一副得得意的樣子。然後把杯子遞給學生，在全班傳了一圈，每個學生都把一個手指伸入混合液中蘸了蘸，然後放進嘴裏，吸吮了一下。他們沒有笑容，而是每個人都做了個苦臉。這混合液太難吃了。

當這個杯子最後傳回老師手中時，他不高興地説：“很遺憾，你們沒有一個人仔細觀察我的動作。不錯，我是吸吮了一個手指，但是放進嘴裏的那個手指並不是我伸進杯子裏的那個。”

這就是我的一節重要的化學課，而我一直沒有忘記這堂課。
