after school this afternoon, on my way home i met two american friends who lost their way. they forgot the way to the hotel where they stayed. as i knew where the hotel was, i decided to take them there. on the road, we talked a lot. i told them about the great changes in the city,such as the wider road, the more convenient transportation, the fresher air and so on.

　　i also introduced that now chinese students needn't spend most of their time on textbooks any more, because they didn't have as much homework as before. in their spare time, they could choose whatover they like to learn. the american friends told me something about the american youth as well.

　　it was late when i got home, but i was very happy. because i not only helped american friends, but also realized the importance of learning a foreign language well.
