77．I'm waiting for my pen pal from America．根据问句What are you doing here？可确定句子回答应用现在进行时态（is/am/are+doing），由She's arriving in 30minutes及A pen pal from merica？可知A正在等他的美国笔友，故此处填写I'm waiting for my pen pal from America．
78．In which language do you write letters？/Do you write letters in English or in Chinese？由We often send emails to each other．可知两人经常写通信，再根据答语Almost in English，可知故此处是询问他们用什么语言写信，故可填写In which language do you write letters？等相关句型．
79．That's true．/That's right．/So they are．根据You know，Chinese characters are difficult for foreigners．可知A说对外国人来说中文太难了，B也同意其观点，故此处可填写That's true等相关句型．
