Answer 1

Nothing is impossible!If you have a dream，your dream will must come true as long as you always work hard．To tell∧truth，my dream is to be a doctor．There was a time that I was in hospital．I saw with my own eyes that a doctor fights all night to save a baby's life．I was touched by the kindly behavior of the doctor．I think doctors are the greatest．We can make patients recover from a disease．However，I am willing to give a hand to who suffers from illnesses．I hope that I'm able to help people keep healthy．At the same time，I will devote myself to treat patients．From now on，I will spare no effort to  study every subjects so that I can go to a key university．
解析：
1．去掉 must．考查情态动词．助动词后不需要情态动词，所以去掉must．
 2．truth前加the．考查冠词．To tell the truth是固定句式，表示"说实话"．
3．that-when．考查定语从句的关系词．定语从句I was in hospital修饰先行词 a time，所以用when在从句了做时间状语．
4．fights-fought．考查谓语动词的时态．根据I saw with my own eyes 可知从句的谓语动词用过去式fought．5．kindly-kind．考查形容词和副词的辨析．修饰名词behavior用形容词kind．
6．We-They．考查代词．代指 doctors 用They，作者还是一个学生．
7．however-Therefore．考查连词．They can make patients recover from a disease．表示"他们能够让病人恢复"；I am willing to give a hand to who suffers from illnesses表示"我愿意去帮助那些有病的人"，所以两句是因果关系，所以用Therefore．．
8．who-whoever．考查宾语从句．本句表示"遭受疾病之苦的任何人"，所以用whoever表示"任何人"．
79．treat-treating．考查非谓语动词． devote myself to 用doing做宾语，所以用treating．
80．subjects-subject．考查名词．修饰词 every 决定后面用可数名词的单数subject．
