Dave is my friend. His family is rich. His parents always give him lots of pocket money. But Dave thinks his parents work very hard and it's not easy for them, so he always tries his best to save money. He has some good ways to do it.

    Dave likes reading. He has lots of books. He tells me he often buys books online, because they're cheaper. And when he has free time, he often goes to bookstores or libraries to do some reading.

    Dave has a bike. He usually goes to school by bike instead of taking a bus. Sometimes when it rains or snows, he walks. These two ways help Dave keep healthy and save some money.

    Dave brings a bottle of water to school every day. When other students drink juice, he enjoys his water. He thinks water is the cheapest but the best drink.

    Some students think Dave is mean. But I don't think so. I think he is right. What do you think of him?

    This is a home of the future, a "smart home", where technology can do almost everything. Imagine we are in the year 2050, ①the computer wakes Tom up in themorning as usual. In front of him is a to-do list of the important events for the day, and it is provided by the computer too. According to Tom's request, the computer serves a list of possible dishes. All the dishes are nice.

    As Tom eats breakfast, the computer reminds him to reply to Lucy. Before Tom finishes his next bite, Lucy's computer receives the message. Then Tom goes to the supermarket. The store's system checks his car when he drives to the pickup area and greets him by name. "Good morning, Tom! Your order is in Case4. Thank you for shopping.'' When Tom removes his order from Case 4, all trades are completed automatically(自动地)over the information superhighway. That is, the money is electronically paid into the bank. Soon after arriving at the office, Tom reads another message from Lucy, telling him that she will go to dinner with him.

    The smart home can also do many other things:

    ◆Find things like keys and mobile phones.

    ◆②        (打开或关闭)machines and lights with your voice.

    ◆Clean your home from clothes to buildings automatically.

    ◆Record everything and everyone entering and leaving the house.

    ◆Take care of each member of the family, young or old.

    ③With the development of technology, the smart home will come true in the future. It is sure to play an important part in our life.

    Most people drink tea in the world. But tea does not mean the same thing to different people. In different countries, people have different ideas about drinking tea.

    In China, for example, tea is often served when people get together. Chinese people drink it at home or in tea houses at any time of the day. They often use hot water to boil tea leaves.

    Tea is also important in other Asian countries. People in these countries have a special way of serving tea. They hold a tea ceremony in their houses when important guests come. It is very old and full of meaning. Everything must be done in a special way in the ceremony. There is even a special room for it in their houses.

    In the United States, people usually drink tea at breakfast or they drink it after meals. Americans usually use tea bags to make tea. This way is faster and easier than the way of making tea in teapots. In summer, most Americans drink iced tea. They like to put some ice in their tea.

Some advice for safety:

    ①Always play in a safe place. A park is a safe place because there are no cars or trucks. But do not talk to anyone you do not know. Never go with a stranger into a motor car.

    ②Before crossing the road, stop and look both ways. Look left, look right, and look left again.

    ③Keep away from houses or buildings that are being built or knocked down. Something might fall on your head, or you might cut yourself on broken glass.

    ④Medicines or pills can be dangerous. Never swallow (吞下) any pills or medicines you find in the cupboard.

    ⑤Wear a life jacket whenever you go out in a boat, Even if you are not in the open sea and the water is not deep, you should have your life jacket on. It's easy to fall out of boat.

    ⑥Do not put your head out of a car, bus or train. Many children have been killed by doing this.

    The giant panda is one of the most popular animals in the world. A giant panda can grow to be 1.5 metres tall and weigh up to 150 kg. People think the giant panda is very lovely. So it is not surprising that the World Wide Fund for Nature chose the giant panda as its symbol. The WWF tells people that giant pandas are in danger and raises money to save them.

    The giant pandas only live in China. There are fewer than 1, 600 giant pandas left in the wild. The main reason why pandas are endangered is that the area where pandas can live has become smaller.

    The WWF works to help giant pandas in the wild in many ways. One of the ways that help them is to increase the size of panda reserves. Some reserves need to be joined together by planting bamboo between them to make "corridors(通道) ". These are paths that lead from one reserve to another. No one may harm the pandas in these areas. The corridors let pandas move from one habitat(栖息地) to another to look for food.

    People are working very hard to make sure the giant pandas do not die out.
