I suggest that we ask users of this machine what they think about it. We can photograph them using it too. Then we can put their comments at the top of the advertisement in big print. We can bring in some humour too. People enjoy reading humorous ads.

我建议我们征询计算机用户的意见。我们也可以把他们使用计算机的情形拍成照片。然后我们把他们的意见用粗体字印在广告上面。我们还可以加入一些幽默故事。人们喜欢幽默的广告。
