before. Talking with people is one of my favorite activities, so being able to speak a new language lets me meet new people, participate in conversations, and form new, unforgettable friendships. Now that I speak a foreign language, instead of staring into space when English is being spoken, I can participate and make friends. I am able to reach out to others and bridge the gap between my language and culture and theirs

Uinta I. Basic listening practice 1. Script M: Do you see yourself as a leader or more of a team player? W: Well, it depends on the circumstances. I usually enjoy working as part of a team and helping everyone work together. But if the leadership is weak, I'm not afraid to take over in order to achieve the goal at hand Q: What does the woman want to be?

#include void main() for(i=0;i<=9;i++) a[=2*计+1; /*为数组a的各元素赋值*

#include void maino a[10] for(i=0;i<10,i++) /产生一个有序的数组*
