Students often like to eat fast foods, especially when they are fairly busy. Can you tell us the advantages and disadvantages of eating fast foods?
The fast foods can save much time. Taking myself for example, if I eat my lunch in a fast food restaurant, usually it may cost me around 15 mins to finish my meal. However, if I eat my lunch in a non fast food restaurant, sometimes I may have to spend around 45 mins to finish. It's really time-wasting for me.
Do you agree or disagree with the statement that nowadays young people know better about the world events than their parents were young.
假设说同意，其中一个观点是young people have wider horizons. 那么好老师展开自己的论述的方式大概是这样的：
Young people have wider horizons. Actually nearly all my friends' parents graduated from the domestic universities. However, nowadays many young students have the overseas study background; they study in America, Britain, Australia and so on. Their horizons tend to be wider.
