In recent years, the Earth has been getting warmer. Average temperatures have risen. Possibly this is natural, but probably we are causing it. Modern people use a lot of electricity and drive a lot of cars. This puts carbon dioxide(二氧化碳)into the air and helps to make the planet warmer. When we hear the news, we may smile. No one likes long, cold winters, but, unluckily, there are many bad points about a warmer Earth.

First, the ice at the Poles melts and becomes water. The result is that the sea level becomes higher. Low islands will vanish(消失). Cities on the coast will be in danger from the sea. Will Tokyo, Bangkok, Hong Kong and Shanghai become like parts of Holland — lower than the sea? Possibly we will have to build walls to keep the water out. Typhoons will become even more dangerous and frightening.

Sadly, the second point is that storms will become bigger. Super-typhoons will be born in the Pacific and do great damage to East Asia. The same will happen to the Eastern United States.

As the weather changes, some places that now have rain will become dry. The farmers will not be able to grow plants. Maybe some dry places will become wet — we don’t know, but we will soon find out, and the change will cause many problems. There might be wars because of it.

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.
