People who like travelling have their reasons.They believe that travelling can help them expand their field of view，especially in the geographical and historical sense.They also think that touring will give them more chances to enjoy different kinds of food and experience new things  that would never be  brought by other activities.But those who dislike travelling also have some reasons.

Travelling，in my opinion，does more good than  harm.Most importantly，it broadens (使扩大) our mind.We can get in touch with other civilizations (文明)，cultures，customs and ideas.

Through history，most people travelled because of necessity (必要性)—not for pleasure.People travelled just in order to remain alive.They searched for food to eat or places to live in.They sometimes ran away from enemies.This is not to say that no one ever travelled just for the fun of it.In ancient times，for  example，rich Romans travelled all the way to Greece to take part in the Olympic Games，and festivals.Of course，some people decided to travel just out of curiosity (好奇心)．They wanted to find out what it looked like beyond the horizon  (地平线)．Also business travel has been going on for centuries.Traders could not only make money but also learn to speak several languages and be introduced to different cultures.

So，travelling does enrich our mind and draw new ideas to us.There is no doubt that we can get much from it.

自古至今，人们都喜欢旅游。不过，在古代，人们旅游更多的是为了生计；而现在，人们旅游是为了增长见识和享受生活。

68．A　词义猜测题。根据第二段出现的broadens及最后一段的enrich，可以推测这里的expand一词表示“扩大、拓宽”之意，widen一词与之意思最接近。

69．D　细节理解题。根据第三段首句Through history，most people travelled because of necessity—not for pleasure.可知在古代人们外出多是为了生计奔波，因此选D项。

70．B　主旨大意题。作者在文中谈了自己对旅游的看法，他认为旅游可以拓宽人们的视野，故选B项。
