More and more people are using cars in many places in Africa today. However, things are different in Malawi(马拉维).Bikes are the most popular in this African country.Bike riding is a way of life in Malawi. People use them to carry heavy things. They also use bikes to carry people, especially tourists. These years, taking a "bicycle taxi" to travel around Malawi has become quite popular among tourists from all over the world.If you go to Malawi, you will find a lot of bike taxis waiting on the sides of the roads. The riders make the bikes comfortable for people to sit on. You can jump on a bike taxi and get around at a very low cost.Alice is a 21-year-old student from Canada. She enjoys the special bike riding a lot. "I really like the bike taxi. " she says. "It's easy and cheap. " Alice usually pays just $1 for going shopping in town.28-year-old Panjira Khombe began to ride a bike taxi two years ago. The young man enjoys this job. "I used to make boats for a living, but that's a hard job. Being a bike taxi rider is easy for me and I don't mind carrying heavy people.

Let's have a flying competition. I'll show you what real flying is ! "One of the swans, a strong young male, took up the challenge. The crow flew up and began to show off his skills. He flew in circles, performed other flying tricks, and then came down and looked proudly at the swan.Now it was the swan's turn. He flew up, and began flying over the sea. The crow flew after him, making all kinds of comments(评价)about his flying. They flew on and on till they couldn't see the land and there was nothing but water on all sides. The crow was making fewer and fewer comments. He was now so tired that he found it hard to stay in the air, and had to struggle to stop himself from falling into the water.The swan pretended not to notice and said, "Why do you keep touching the water, brother? Is that another trick?""No, " said the crow. He knew he had lost the competition. "I'm in trouble because of my pride! If you don't help me, I'll lose my life... "The swan took pity on him, and took him on his back and flew back to the beach.30.What's the correct order of the following events?a.The crow showed off his flying skills.b.The swan took pity on the crow and saved him.c.The crow laughed at the swans' flying.d.The crow followed swan and got into trouble.e.The crow challenged swans and a strong young swan accepted it.A. e,c,d,a,bB. a,e,c,d,bC. c,e,a,d,bD. e,a,d,c,b31.Why did the crow keep touching the water?A.

Flying skills were useless.C. The swan saved the crow because they were good friends.D. The swan was better at long-distance flying than the crow.COnline shopping has become something very common for young people. However, it's not easy for old people. Therefore, buy-for-you shops, are becoming popular among the old.Mr. Li, a 65-year-old man, is crazy about this way of shopping. He says, "I can't use the Internet. After I happened to find a buy-for-you shop, I decided to try. Finally I got what I wanted.I was so happy. "The shopkeeper Mu Lan says she started the business of offline buy-for-you in order to help people like Mr. Li. In only about ten days since the start of the business, she has received more than20 orders from customers. Mu Lan is not the only one who finds the large need of offline buy-for-you business in the market. In her city, over 300 such shops opened their doors only in April.In order to attract more customers, they have opened their shops in communities. And they charge a suitable service fee(费用). For example, when buying things that cost less than 200 yuan for customers, they usually get 5 yuan as service fee.What if there is any problem with the ordered thing, let's say, like a quality problem?

True or FalseMaking E-palsThe Internet is a very fun and useful tool. There are so many things you can do on the Internet. And you can find many e-pals on the Internet, too. An e-pal is someone who you talk to online and probably have never met. E-pals often live in another city, or even in another country! Though making e-pals is fun, it is important to remember that you need to be careful. Because you have no way to know whether they are telling the truth. You shouldn't give them too much personal information, such as your telephone number or home address. There may be many people that you talk to online, but they don't know you in the real world. An e-pal can never replace (代替)your true friends. A good friend will know all about you and be there when you need them. You can spend time with them and share your feelings. If you have e-pals, enjoy talking with them online, but don't forget your other true friends. Remember to balance your time among friends and you will have a good time!( ) 58.Many e-pals on the Internet are very interesting and useful.( ) 59. E-pals may be in different cities and countries.( ) 60. You needn't be careful to make e-pals because it is very fun.( ) 61 .We must keep our own personal information carefully on the Internet.( )62.
