It is August 2050. Mrs Peng and Mr Yu are writing about hotels and houses on their posts.

    The Hotel Whale

    The Hotel Whale is built (A) 在水下. It is in the shape of a whale. This hotel has 50 bedrooms, a cafe and a shopping centre.

    Mrs Peng: "When we were staying at the hotel recently, my children watched the fish outside their bedroom window. (B)They were never bored."

Forever Green Houses

These houses are both "green'' and "smart". There is glass outside the houses. Heat is held under the glass and is then used as energy for(C) each house. In the bathroom. Your medicine cupboard is connected to your doctor's computer. In the kitchen, your smart fridge tells the supermarket's computer when you (D)need more food.

    Mr Yu: "When we were living in our old house, we were using more energy. J would certainly recommend Forever Green Houses to my friends. (E)They will satisfy everyone.''

    Everyone needs friends. We all like to feel close to someone. It is nice to have a friend to talk, to laugh, and to do things with. Surely, sometimes we need to be alone. We don't always want people around. But we would feel lonely if we never had a friend.

    No two people are the same. Sometimes friends don't get on well. That doesn't mean that they no longer like each other. Most of the time they will make up(和解) and become friends again.

    Sometimes friends move away. Then we feel very sad. We miss them very much, but we can call them and write to them. It could be that we couldn't even see them again. And we can make new friends. It is surprising to find out how much we like new people when we get to know them.

    There's good news for people who have friends. They live longer than people who don't. Why? The reason could be that they are happier. Being happy helps them stay well. Or the reason could be that they know that someone cares them. If someone cares about you, you would also take good care of yourself.

    Are you shy? If you are, you are not alone. In fact, close to 50 percent of people are shy. Almost 80 percent of people feel shy at some point in their lives. These days, shyness is becoming more and more common. Now, scientists are trying to understand shyness. They have some interesting ideas about why people are shy.

    Is it possible to be born shy? Many scientists say yes. They say 15 to 20 percent of babies behave shyly. These babies are a little quieter and more watchful than other babies. Interestingly, these shy babies usually have shy parents. As a result, scientists think that some shyness is genetic.

    Family size might cause people to be shy as well. Scientists at Harvard University studied shy children. They found that 66 percent of them had older brothers and sisters. The scientists said that these children were often bullied(欺负)by their older brothers and sisters. As a result, they became shy. At the same time, children with no brothers and sisters may be shy as well. Growing up alone, they often play by themselves. They are not able to learn the same social skills as children from big families.

    You may also be shy because of where you were born. When scientists studied shyness in different countries, they found surprising differences. In Japan, most people said they were shy. But in Israel, only one of three people said so. What explains the difference? One scientist says the Japanese and Israelis have different opinions of failure. In Japan, when people do not succeed, they feel bad about themselves. They blame(责备)themselves for their failure. In Israel, the opposite is true. Israelis often blame failure on outside reasons, such as family, teachers, friends or bad luck. In Israel, freedom of opinion and risk taking are strongly supported. This may be why Israelis worry less about failure and are less shy.

    For shy people, it can be difficult to make friends, speak in class, and even get a good job. But scientists say you can get over your shyness. They suggest trying new things and practicing conversations. And don't forget-if you are shy, you are not the only one.
