be absorbed in 后可以加doing sth.还有focus one's attention on ,on后 pay attention to(doing) sth注意,留意fix one’s attention/ eyes on be absorbed in（doing）sth 您好请问 pay attention to 和 focus one's attention on 有哪些区别? focus one's eyes on 英语翻译第一个用be absorbed in来造句 第二个用draw one‘s attention来造句 短语stay in , leave for,upon one's arrival on doing sth 什么意思? live on 后接doing sth 还是to do sth? focus on sth Egyptians focus their attention on recovering the nation's m spend ...on(in) doing sth ---------------------------------- take part in和join in 和 join后可以加doing sth 形式么?
