1 . When you’re not at home, many worries may start to fill your mind. Did I turn off TV? Did I close the door? With a smart（智能的）home, you can keep all of these worries off.
A smart home is a home with a network（网络）. This network connects many things in our houses, such as our lights and TV sets, and allows you to control everything in your home from far away through your mobile phone over the Internet.
More and more people may start to get a smart home, because it makes life much easier. It can help keep your room at a certain temperature. It can help you know what happens inside the home and send the video to your phone. When you are on holiday abroad, you can use a smart home controller（控制器）to turn on or off the lights, the fridge and so on. Some smart homes can receive a visitor, allowing him to come in and offering him a drink. They can even feed the cat and water the plants.
Besides, smart homes are easy to fix and people can set up the smart homes by using only the guiding information. When something wrong appears, you can only use the guiding information to deal with it yourself without paying anybody.
But for home-users, the smart home is far from perfect. It can be quite expensive to get. Also, because the smart home system（系统）allow its owner to get home information from anywhere, it is easy for bad people to secretly use or change the information in the system.
Now, many scientists are excited at the future of smart home. Whatever it is, one thing is for sure—the smart home will change the way we live and work.

2 . Cold weather has a great effect on how our minds and our bodies work. Maybe that is why there are so many expressions that use the word “cold”.
For example, people who show no human emotions or feelings are said to be cold-blooded. Cold can affect other parts of the body. But the expression “get cold feet” has nothing to do with cold or your feet. The expression means being afraid to do something you have decided to do. For example, you agree to be CEO of a company. But then you learn that all the other officers have resigned (辞职), and all the work of the company will be your responsibility (责任). You are likely to get cold feet about being CEO when you understand the situation.
The expression “give someone the cold shoulder” probably comes from the physical act of turning your back toward someone, instead of speaking to him face to face. You may give the cold shoulder to a friend who has not kept a promise he made to you, or to someone who has lied about you to others.
“A cold fish” is not a fish. It is a person. But it is a person who is unemotional and shows no love or warmth. A cold fish does not offer much of himself to anyone. Someone who is a cold fish could be cold-hearted. He or she will never feel sorry for those in bad situation.
“Out in the cold” means not getting something that everybody else got. A person might say that everybody but him got a pay raise — he was left out in the cold. And it is not a pleasant place to be.
