If you are given only 1 yuan, could you live in a city for one day? It seems this may be a little difficult. But students from Xi'an did it.

On April 10, more than 60 students from the Middle School Attached to Northwestern Polytechnic University took part in the One Yuan Metropolis Survival. The charitable organization for teenagers called Imperceptible Education held this activity. Students not only have to live, but they also have to deal with a lot of hard tasks. It has happened in eight cities and is going to four others, including Beijing, in June.

To make money, many students looked for part-time jobs and saw how hard life was. Zhang Queue, 14, asked more than 10 restaurants for a job and finally got one chance. “We were sad when they said no. But gradually (逐渐地), we got used to it,” he said. After being a waiter for an hour, he got 25 yuan.

Some made use of their talents by singing and dancing in parks or shopping malls. Many people who walked by took notice and helped them. Zhao Jincheng, 14, drew pictures and made paper crafts(手工). “This showed it's important to learn a special skill,” he said.

Living was hard, but finishing the tasks wasn't any easier. They went to different places to finish tasks in a short time. The most amazing one was when they had to exchange things worth thousands yuan with only a piece of paper in half an hour. “We learned how to persuade others. From a balloon to a cake to a bottle of yogurt (酸乳) … after almost 20 tries, we got an expensive necklace,” he said. They will give all of the money they made to poor schools in Tibet.

(1) According to Paragraph 2, which of the following is correct?

a. adults can join this activity

b. students are given a little money

c. students have to do hard tasks

d. twelve cities have joined this activity

A. a, b B. b, c C. c, d D. a, d

(2) To make money, students tried many things EXCEPT ____________. A. going to Beijing to do their tasks B. working part-time jobs C. giving talent shows D. drawing and making paper crafts

(3) During this activity, _____________. A. Zhang Queue gave up when he was refused B. students learned that life is hard C. Zhao Jincheng made money by singing D. students learned how to make paper crafts

(4) What does the underlined word “persuade” in the last paragraph mean? A. argue with others B. show sth. to others C. sell something to others D. make sb. do sth.

When you are travelling in Thailand, which means of transport is the best choice?

You can rent a variety of motorbikes or bikes in Thailand. It seems to be very popular in most of the beaches and islands along the places in the north. The most popular bikes are the little 125 cc Honda Dream which you can get for about 150 baht (铢) a day or as little as 3,000 baht per month, making it the cheapest way to tour Thailand for the people from other countries.

Sometimes you will have to go somewhere by taxi. When you are in cities in Thailand, especially in Bangkok, always remember to get a taxi that is traveling on the roads. Some drivers outside hotels refuse to use the meter (计程表). They will ask a price which is several times the price when they use the meter!

The quality of the roads in Thailand is generally pretty good, so renting cars is another way to get around. The big car rental companies may offer you slightly older cars at a very reasonable (合理的) price. It is a little surprising considering that the cost of buying a car in Thailand is more than that in the West. Petrol is also reasonably priced in Thailand, more expensive than American prices, but much cheaper than what is paid in Europe. In the past, Bangkok could be a difficult place to drive in—signs were generally in Thai only, making it a hard job to find exactly where you were by looking around. But now, the situation is improved. In a lot of places, even the farthest corners of the country, street signs are in both Thai and English.

(1) To a foreigner, the most economical way to get around Thailand is renting a ________. A. motorbike B. car C. taxi D. bike

(2) What is the writer's advice about taking a taxi in Thailand? A. To make sure there is a meter in it. B. To take a taxi parked outside hotels. C. To take a taxi going on the road. D. To bargain with the driver over the price.

(3) It was difficult to drive in Bangkok in the past because ________. A. there were too many traffic jams on the roads B. the signs were written only in their own language C. there were no signs at the farthest corners D. the quality of the roads was not good
