For teenagers, it's great fun to explore new places and it feels like an adventure, even when you know you're not the first to have been there. But to make sure not to get lost or waste time going round in circles, the following tips may be helpful.

◆Do the map reading if you're being driven somewhere. It'll be easier if you keep the map following the direction you are traveling in. Keep looking ahead so that you can give the driver lots of warning before having to make a turn, or you'll have to move to the back seat.

◆ Get a group of friends together and go exploring. You'll need a good map, a compass , a raincoat, a cell phone to call for help in case you get lost, and a bit of spare cash for emergencies .Tell someone where you're going before you set out and let them know what time you expect to be back. The purpose of the activity is in not getting lost, not in seeing how fast you can go, so always stick together, waiting for slower friends to catch up.

◆See if your school or a club organizes orienteering(越野识途比赛)activities, in which you need a map and a compass to find your way. This can be done as a sport, with teams trying to find the way from A to B(and B to C, etc. ) in the fastest time, or simply as a spare-time activity. It enables you to be familiar with the use of maps and compass and gain some special skills. In some way, it’s not only good fun, but also a great way to keep fit.

21.When you sit beside the driver, you’d better________.

A. look ahead to see where there is a gas station

B. move to the back seat if feeling uncomfortable

C. keep looking at the map to find another place to go to

D. direct the driver when necessary

22.In the exploration, why do you need wait for the slower friends?

A. To share the fun with him/her in exploration

B. To tell him/her what’s going on with group members.

C. To avoid yourself or your friends getting lost

D. To show them how fast you can go

23.What does the whole passage talk about?

A. the fun of exploration B. what to bring for exploration

C. how to prevent people getting lost in exploration

D. the way to use a map in exploration

B

David and Amir first met in their chemistry class at an American university. Amir was an international student from Jordan. He was excited to get to know an American. He wanted to learn more about American culture and hoped that he and David would become good friends. At first, David seemed very friendly. He always greeted Amir warmly before class. Sometimes he offered to study with Amir. He even invited Amir to have lunch with him. But after the term was over, David seemed distant. The two former classmates didn’t see each other very much at school. One day Amir decided to call David. David didn’t seem very interested in talking to him. Amir was hurt by David’s change of attitude. “David said we were friends,” Amir complained. “And I thought friends were friends forever.” Amir is a little confused.

As a foreigner, he doesn’t understand the way Americans view friendship. Americans use the word “friend” in a very general way. They may call both casual acquaintances(熟人) and close companions “friends”. These friendships are based on common interests. When the shared activity ends, the friendship may be gone. Now as David and Amir are no longer classmates, their friendship has changed. In some cultures friendship means a strong lifelong bond between two people. In these cultures friendships develop slowly, since they are built to last. American society is one of rapid change. Studies show that one out of five American families moves every year. American friendships develop quickly, and they may change just quickly as well . People from the United States may at first seem friendly. Americans often chat easily with strangers. But American friendliness is not always an offer of true friendship. After an experience like Amir’s people who’ve been in this country for only a few months may consider Americans to be changeable. Learning how Americans view friendship can help non-Americans avoid misunderstandings. It can also help them make friends in the American way.

24.According to the passage, ______ made Amir a little confused.

A. David’s inviting him to dinner B. David’s studying with him

C. David’s cold attitudeD. David’s misunderstanding him

25. In paragraph 2, the underlined word “ they” means_____.

A. American families B. American friendships

C. people from the United StatesD. misunderstandings

26. Why do American friendships develop and change so quickly?

A. Americans may not only call casual acquaintances but close companions “ friends”

B. American society is one of rapid change, and the families move frequently.

C. Americans often seem friendly, and chat easily with strangers at first.

D. Americans think friendship means a strong lifelong relationship between two people.

27. This passage mainly tells us_____.

A. how Americans view friendship B. that everyone needs friends.

C. the importance of keeping friendship

D. that people should not make friends with Americans.

C

Terrible disasters in the last 50 or 100 years have become increasingly common. Over the last 30 years, the number of weather-related disasters has increased quickly, and the disasters have also affected more people and caused more economic loss. However, much of this could be avoided through disaster risk reduction(DRR降低灾难风险).

A meeting, held in Sendai, Japan last month, opened one day after Cyclone Pam(飓风Pam)hit Vanuatu, which struck the islands with winds of up to 340km/h and destroyed the island nation. The speech by the President of Vanuatu was given shortly after that. He begged the international community for support and stronger commitment (承诺)to helping them manage climate and disaster risks. In the face of disasters, it is always the developing countries that suffer most. Damage in these countries is often worse and unluckily, there is limited money and technique to prevent these disasters.

In fact, we have seen Asian countries-especially those that have suffered a lot in disasters can’t pay the price. Great loss Asia has suffered comes to a total of almost $ 53 billon yearly over the past 20 years.

At the same time, studies have shown once again that proper prevention saves lives and damage. With this in mind, people at the Sendai meeting were able to come up with new agreements that effective ways of disaster risk reduction will be carried out in the coming years for those who easily get damaged in disasters.

28.According to the first paragraph, disasters ________.

A. can all be prevented B. have become more frequent

C. are all weather-related ones D. affect fewer people than before
