[02:19.10]READING

[02:23.65]FRANKLIN'S FAMOUS KITE EXPERIMENT

[02:28.01]In the eighteenth century,

[02:31.54]Benjamin Franklin conducted a number of experiments

[02:36.81]in which he showed what eleetrieity is.

[02:41.49]Here is how he deseribed one of his experiments.

[02:46.64]In June 1752,I wanted to show that lightning and electricity are the same.

[02:55.18]Having realised that I could use a kite to attract lighting 4,

[03:01.66]I decided 5 to do an experiment.

[03:06.02]I built a strong kite and waited for bad weather.

[03:11.48]When the first thunderstorm came,

[03:15.74]I took my condenser 6 to a shed 7 in the fields where I could do my experiment.

[03:22.50]My son helped me fly the kite.

[03:26.94]The kite flew high in the rainy sky,but nothing happened.

[03:32.69]I was beginning to think that the experiment would not work.

[03:38.57]Just then,I saw some of the hairs on the string stand up.

[03:44.91]The string was getting charged!

[03:48.96]I brought my finger close to the key

[03:53.33]and felt a light but very clear electric shock.

[03:58.68]Others followed even before the whole string was wet,

[04:03.85]and I was able to collect and store a great deal of electricity in the condenser.

[04:11.12]This experiment proves that lightning and electricity are the same.

[04:17.46]To do the experiment you need four things:

[04:22.22]a kite,a key,some really bad weather and a condenser,to store electricity.

[04:30.68]Most kites are made of paper,

[04:34.44]but a kite made of silk

[04:38.00]will not tear so soon in weather with rain and strong winds.

[04:44.16]Build the frame 8 of the kite by making a small cross of two pieces of light wood.

[04:51.81]The pieces should be just long enough to reach the corners of the handkerchief.

[04:58.58]Tie the corners of the handkerchief to the points of the cross,

[05:04.46]and you will have a nice strong kite.

[05:09.50]Add a tail to the frame

[05:13.16]and tie a long string to the cross so you can control the kite.

[05:19.43]The next three steps are very important.

[05:23.87]First,fix a very sharp piece of metal,

[05:29.01]pointing a foot or more above the frame,

[05:33.45]to the top of the longer stick of the cross.

[05:38.42]Second,fasten a key to the end of the long string.

[05:44.37]Third,tie a silk ribbon to the string,just above the key.

[05:50.93]This ribbn,which must not get wet,will protect you from the electricity.

[05:57.88]Fly the kite when a thunderstorm appears to be coming on,

[06:03.44]Stand inside a door,or under some cover,

[06:09.11]so that the silk ribbon does not get wet.

[06:13.05]Take care that the string does not touch the wall or the door.

[06:18.93]When a thundercloud comes over the kite,

[06:23.19]the sharp piece of metal will pull the electricity from the cloud.

[06:29.43]The kite and the string will become charged.

[06:34.00]When the kite and the string are wet from the rain,

[06:38.76]they will conduct the electricity very well.

[06:43.41]You can collect and store the electricity

[06:47.98]in the condenser and use it for other experiments.

[11:02.15]POST-READING

[11:06.31]After reading the READING piece a second thime and doing the POST-READING,

[11:18.14]try to translate the whole piece sentence by sentence into correct Chinese.

[11:35.38]Then read the Chinese translation on page___

[11:51.73]and translate it sentence by sentence back into English,

[13:04.77]LANGUAGE STUDY

[13:09.52]Word Study

[13:14.10]While reading and doing all the exercises on page 26,

[13:19.74]try to add one sentence to each of the 18 sentenees in Word study

[13:38.31]and study carefully Word Conversion 9


[13:43.35]in which a word may be changed into different parts of speech without

[13:49.41]changing its spelling or very often even without changing its pronuneiation.

[14:01.87]Then try to find more different uses of the words:

[14:24.24]charge,conduct,cross,sharp,tear,and tie in an English-English dictionary.

[14:52.58]charge=claim that a person has done wrong,

[15:19.72]esp a formal claim that he has committed a crime:

[16:14.97]aeeuse sb of sth,esp formally in a court of law:

[17:15.52]With the help of an English-English dictionary,

[17:20.38]make pairs of sentences with some meaningful context 10,

[17:32.53]using words such as thunderstorm,football,shoestring,ice-cream,greenhouse 11,

[18:15.18]downtown,and sea-foods.

[18:21.24]A greenhouse is a building with sides and roof of glass.

[18:52.23]After reading all the three passages on pages 27-28,

[19:07.66]try to translate them sentence by sentence into eorrect Chinese.

[19:47.60]make as much comparison 12 as you can between the English text and the Chinese

[20:10.46]* Answers and helps will be given in the other units some time later
