单项选择题

Most of us trade money for entertainment. Movies, concerts and shows are enjoyable but expensive. (78) If you think that you can’t have a good time without spending a lot of money, read on. A little resourcefulness and a few minutes of newspaper-scanning should give you some pleasant surprises.
People may be the most interesting show in a large city. Stroll through busy streets and see what everybody else is doing. You will probably see people from all over the world; you will certainly see people of every age, size, and shape, and you’ll get a free fashion show, too. Window-shopping is also a safe sport-if the stores are closed.
Check the listings in your neighborhood paper. Local colleges or schools often welcome the public to hear an interesting speaker or a good debate. The film or concert series at the local public library probably won’t cost you a penny. Be sure to check commercial advertise-ments too. A flea market can provide hours of pleasant browsing. Perhaps you can find afree cooking or crafts in a department store.
Plan ahead for some activities. It is always more pleasant not to have people in front of you in a museum or at a zoo. You may save some money, too, since these places often seta side one or two free admission days at slow times during the week. (79) Pretend that you are a tourist from time to time, and get to know your city all over again including the indis-pensable (不可错过的) sights that people travel miles to see. If you feel like taking an in-teresting walk, find a free walking tour, or plan one yourself. You will see your city in anew perspective (视角) once you know more about its history or its architectural treas-ures. With imagination and a spirit of adventure you can quite easily find good entertain-ment at no cost at all.

If you are wandering through the busy streets, which will most attract you

A．Various buildings

B．Car driving

C．Window-shopping

D．Free walking
