[00:09.20]Lesson 17 1.Read and act
[00:15.36]During the break,
[00:18.52]Li Lei happened to see Paul's mark on the report of a chemistry experiment.
[00:25.08]Oh,Paul,you got another "A+". Congratulations!
[00:30.64]Thank you.
[00:33.20]I wonder how you've done so well in every chemistry experiment.Any secret?
[00:39.86]Well,there's no secret at all.
[00:43.62]I just listened to and watched the teacher carefully
[00:48.98]while he was doing the experiments. Really?
[00:54.26]I should thank my first chemistry teacher for this.
[00:59.12]he told us about the importance of observation
[01:04.16]in his first lesson in a strange way,and I'll never forget it.
[01:09.93]Oh,that sounds interesting.Come on,tell me about it. OK. ...
[01:19.78]Lesson 18
[01:22.94]2.Read Look Carefully and Learn
[01:28.50] I will never forget my first chemistry teacher.
[01:33.47]he was a little man with thick glasses,
[01:38.43]but he had a strange way of making his class lively and interesting.
[01:44.96]And his lessons were not easily forgotten.
[01:49.79] I remember the first lesson of this teacher.
[01:54.23]After we were all in the chemistry lab,
[01:58.60]the teacher brought out three bottles.
[02:02.75]One was filled with petrol,one with castor oil and one with vinegar.
[02:09.83]"Now watch carefully,"said the teacher.
[02:13.77] He then filled a cup with some of the petrol,
[02:18.21]some of the castor oil and some of the vinegar.
[02:23.05]As we watched him quietly,he mixed the three together.
[02:28.90]After that,he held up one of his fingers and showed it to the class.
[02:35.38]he then dipped it into the cup.
[02:39.14]After a few seconds,he took his finger out.
[02:44.28]"Now watch,"he said."Remember,you must do everything as I do."
[02:51.52]He put a finger in his mouth,tasted it and smiled,looking rather pleased.
[02:59.25]Then he handed the cup around us.
[03:03.22]Each of us dipped a finger into the mixture and sucked it.
[03:08.68]Instead of smiling,we all made faces.
[03:14.04]The mixture tasted terrible.
[03:18.09] When the cup was at last returned to the teacher,he said sadly,
[03:23.65]"I'm sorry,none of you watched carefully enough.
[03:28.90]Yes,I sucked a finger,
[03:33.34]but the finger I put into my mouth was not the one I had dipped into the cup."
[03:40.58] This was my first lesson in chemistry and I never forgot it.
[03:49.83]Lesson 20 3.Read
[03:54.68]Once upon a time,there lived a poor farmer in a village.
[04:00.74]One day as he was driving home from the market,he dropped his knife.
[04:07.90]He jumped down from the wagon and began to look for it.
[04:13.86]He looked around for a long time in all the junk that littered the ground,
[04:20.91]but still could not find it.
[04:25.17]After a while,he took an empty bag form the wagon
[04:31.33]and began to fill it with papers,rags,broken dishes and bottles.
[04:39.67]Soon the bag was full,and he found the knife among the junk at last.
[04:47.61]he put the bag of rubbish in his wagon and got on it.
[04:53.96]When he looked at the ground around him,
[04:58.32]he found it much cleaner than the rest of the roadside.
[05:03.96]He decided to bring a bag to clear a little more of the land every market day.
[05:11.41]Soon all the land he passed looked green and lovely,
[05:17.65]and the farmer was pleased to look at it.
[05:22.32] Before long the King came riding along the road.
[05:27.78]He was so happy to see flowers and grass instead of rubbish on both sides.
[05:36.04]When he knew what had happened,he gave the farmer a reward.
[05:42.57]Then he ordered the people of his kingdom to follow the farmer's example.
[05:49.73]Soon his kingdom became a land of beauty |
