有错误，as soon as 是一……就……的意思，是条件状语从句的连词，状语从句要注意主将从现，即主句用将来时，从句用一般现在时表将来。As soon as my friend arrivedby plane, she will phone me at once.或者这句话讲的是过去的，所以连词改为when会比较好，这句话改为When my friend had just arrived by plane, She phoned me at once.意思为当我的朋友乘飞机到达的时候，她马上给我打了电话。 My friend had just arrived by plane用过去完成时，强调的是她到达是在她给我打电话之前。...
