I like digital products. It is advanced and convenient. For example, nowadays our family has a digital camera. We can take pictures whenever we want. We have taken many photos about our life. But in the past, if we want to take pictures, we have to go to the photographic studio. It is inconvenient and expensive. So we only take photos once a year. This is one classical example. There are many similar examples.

我喜歡數碼產品。它們先進、方便。舉個例子，我們家現在有一個數位相機。我們什麼時候想照相都可以。這相機記錄了我們生活中很多的點點滴滴。但是，過去，如果我們想拍照，我們只能去影樓。一點都不方便也很貴。所以我們每年只拍一次照片。這是一個典型的例子。很有很多類似的呢。
