At the present time, more and more people love travelling. It's a very good 1 of getting to know new people and cultures and acquiring (获得) experiences. It helps travelers 2 a lot. Travel can make our minds become 3 .
But travel does more than all that. It can also make us more creative. In recent years, some professors have been doing research on what many people have already learned from travel experiences. They believe that spending time abroad has the 4 to affect (影响) people's mind. For example, they found that the students who lived abroad for a longer period were better at 5 problems creatively than those who did not. If you stay in the same place, you can't experience new sights, new smells, new sounds and new cultures. All these can 6 your mind and make it more active.
7 , that doesn’t mean the more places you’ve been, the more creative you’ll become. Another group of professors have been doing 8research. They found the people who often travelled from one place to another didn't have enough 9 to immerse（使……沉浸）themselves in a new place and a new culture. They weren’t as creative as the people who spent the time 10 getting to know a place. You have to interact（相互影响）with the places you go to and then you can benefit（得益）from it.
If you go travelling. which do you prefer, staying in a place for a certain period or rushing all the way ?
