【考点】图表作文．

【答案】Recently，students in our class have had a discussion about whether we should develop driverless car.
Some students think that driverless cars have their advantages.They can reduce traffic accidents caused by human faults.Besides，it is convenient for the elderly and the disabled to move around on their own.However，some students argue that driverless cars have disadvantages.For example，they are time-consuming.What's more，it is not affordable for ordinary people.
In my opinion，technology brings us convenience，but it also led to many problems.Only if we use it wisely，can we live a better life.
