【答案】that错误，改为which；written错误，改为writing；will to错误，改为will；in June 15错误，改为on June 15；starts错误，改为start；student 错误，改为-students；giving错误，改为given；so错误，改为if；call me错误，改为call me at；for错误，改为to。
【解析】① that错误，改为which 考査引导词,此处指的是前面的事, which可以在从句中中做主语,而that不可以,故that错误，改为which。
②written错误，改为writing 考査固定用法, be writing to：写作是为了……，故written错误，改为writing。
③will to错误，改为will 考查固定用法。情态动词will，后面加动词原形，故will to错误，改为will。
④ in June 15错误，改为on June 15 考查固定用法。具体到某天的时候介词应该用on。故in June 15错误，改为on June 15。
⑤starts错误，改为start 考查固定用法。情态动词will，后面加动词原形，故starts错误，改为start。
⑥student 错误，改为-students。考查名词单复数。因为前文的ten，可知此处是十个学生，应该用复数形式。故student 错误，改为-students。
⑦ giving错误，改为given考查被动语态。此处指的主题为……的演讲，主题是被赋予的，应该用被动语态。故giving错误，改为given。
⑧so错误，改为if 考查连词。句意：如果您方便的话，我们希望您能接受我们的邀请。故so错误，改为if。
⑨call me错误，改为call me at 考查固定用法。all sb at...拨打......(号码)给某人。故call me错误，改为call me at。
⑩ for错误，改为to考查固定用法。all sb at...拨打......(号码)给某人。故for错误，改为to。
