In order to promote participation in outdoor exercise，our school had organized an activity to climb the West Mountain on April 10．The moment we arrived at the foot of a mountain，we set out for the top in high spirit．We supported each other to pass the rocky areas on the course of the climb．Laughing and cheering，we eventually reached the summit，there we were greeted by the bright sunshine and fresh air．Viewing from the top，the city was extreme beautiful．This event was very beneficial，for not only∧we take a break from our heavy school workload，but we also learned what to cooperate．Therefore，we strongly suggest that similar events are held every year!
详
1．had去掉；时态错误．句意表达的是过去的事实，不能用过去完成时态．
2．an改为the；冠词错误．句意表达的是特指，要用定冠词．
3．spirit改为spirits；短语搭配错误．in high spirits兴高采烈．
4．on改为in/during；介词错误．句意表达的是在爬山的过程中．
5．there改为where；连词错误．句中we were greeted by the bright sunshine and fresh air修饰名词summit，是一个非限制性定语从句；从句结构完整，且先行词summit表示地点，要用where来连接．
6．Viewing改为Viewed；分词错误．句中view与主语the city构成动宾关系，要用表示被动的过去分词作方式状语．
7．extreme改为extremely；副词错误．句中extreme修饰形容词beautiful，要用副词形式．
8．加did；句型结构错误．句中not only位于句首，句子要部分倒装；句意表达的是过去发生的动作，要添加助动词did来体现时态．
9．what改为how；特殊疑问词错误．句中特殊疑问词后接不定式，构成复合不定式短语；句意表达的是方式，要用how来构成．
10．are改为be；句子结构错误．句中suggest后接宾语从句，从句要用should加动词原形，should可以省略． In order to promote participation in outdoor exercise，our school had organized an activity to climb the West Mountain on April 10．The moment we arrived at the foot of a mountain，we set out for the top in high spirit．We supported each other to pass the rocky areas on the course of the climb．Laughing and cheering，we eventually reached the summit，there we were greeted by the bright sunshine and fresh air．Viewing from the top，the city was extreme beautiful．This event was very beneficial，for not only∧we take a break from our heavy school workload，but we also learned what to cooperate．Therefore，we strongly suggest that similar events are held every year!
