【题目】 According to some experts, a smart home is now available(可得到的). There are coffee pots that turn on when the alarm clock rings. There are fridges that send an alert when the milk runs out. These smart appliances are changing our lives greatly.

However, it seems few people are making their homes smart. In a U. S. survey, only six percent of American families have a smart appliances. More than 70 percent of people have no plans to buy smart appliances in the next two to five years.

Why are smart home appliances having a hard time reaching the market? There are several reasons. First, a lot of smart appliances are just fun. They are not essential(必要的). Many of them are too expensive. One of Samsung’s smart fridges have cameras inside. It can check for rotting food. It can also allow the user to know what he is short of while he’s shopping. However, the fridge sells for $5,000. People who can afford it probably don’t do their own shopping. For the rest of us, we regularly check the food in our fridges, don’t we?

The technology is not yet perfect, either. There are complaints that smart appliances sometimes stop working or become dull.
