5个英语句子谁能帮我改一下

不知解释正确否,解释错了别笑话,咱水平也很有限.
1句 动词ate换过去分词aten 另外therefore后缺少主语we（个人认为）
2句 情态动词will不能在句子中担任谓语,应此youll faint from exhaustion
应改成you will be faint from exhaustion
3句 动词seen为过去分词,直接改为动词过去式saw就可以
4句 who are reading the short story 为students的定语从句,应为从句中缺少主语,所以用关系代词who来指代students也作丛句的主语.而theyll share it in calss 也是 open boat 的定语从句,应为这个从句中句子主谓宾结构完整,所以应该用关系副词来引导这个句子,本人认为应该用where,既是there are two students who are reading the short story called the open boat where theyll share it in calss
5句 原句中句子没结构,应该把don't变为not to,既是anna exclaimed not to touch that hot frying pan,这样anna为主语 exclaimed为谓语 not to touch为不定式否定式做直接宾语,that hot frying pan.为间接宾语
