问题 设计任务：请阅读下面学生信息和语言素材，设计一个25分钟的阅读训练活动。教案没有固定格式，但须包含下列要点：teaching objectiveskey and difficult pointsmajor steps and time allocationactivities and justifications教学时间：25 minutes学生概况：某城镇普通中学高中一年级学生，班级人数40人。多数学生已经达到《普通高中英语课程标准(实验)》五级水平。学生课堂参与积极性一般。语言素材：Franklin′s Famous Kite ExperimentIn the eighteenth century,Benjamin Franklin conducted a number of experiments in which he showed what electricity is.Here is how he described one of his experiments.In June 1752,I wanted to show that lightning and electricity are the same.Having realized that I could use a kite to attract lightning,I decided to do an experiment.I built a strong kite and waited for bad weather.When the first thunderstorm came,I took my condenser to a shed in the fields where I could do my experiment.My son helped me fly the kite.The kite flew high in the rainy sky,but nothing happened.I was beginning to think that the experi-ment would not work.Just then,I saw some of the hairs on the string stand up.The string was getting charged!I brought my finger close to the key and felt a light but very clear electric shock.Others fol-lowed even before the whole string was wet,and I was able to collect and store a great deal of electricity in the condenser.This experiment proves that lightning and electricity are the same.To do the experiment you need four things,a kite,a key,some really bad weather and a condenser,to store electricity.Most kites are made of paper,but a kite made of silk will not tear so soon in weather with rain and strong winds.Build the frame of the kite by making a small cross of two pieces of light wood.The pieces should be just long enough to reach the comers of the handkerchief.Tie the comers of the handkerchief to the points of the cross,and you will have a nice strong kite.Add a tail to the frame and tie a long string to the cross so you can control the kite.The next three steps are very important.First,fix a very sharp piece of metal,pointing a foot or more above the frame to the top of the longer stick of the cross.Second,fasten a key to the end of the long string.Third,tie a silk ribbon to the string,just above the key.This ribbon,which must not get wet,will protect you from the electricity.Fly the kite when a thunderstorm appears to be coming on.Stand inside a door,or under some cover,so that the silk ribbon does not get wet.Take care that the string does not touch the wall or the door.When a thundercloud comes over the kite,the sharp piece of metal will pull the electricity from the cloud.The kite and the string will become charged.When the kite and the string are wet from the rain,they will conduct the electricity very well.You can collect and store the electricity in the condenser and use it for other experiments.
