解析：【小题1】when when引导的是时间状语从句，句意：当我开始学英语的时候…
【小题2】it 代词It指代English作为find的宾语。
【小题3】The 用the特指上文提到的那位老师。
【小题4】whose 本句是定语从句,whose指代先行词the one，在定语从句中放在classes前面做定语。
【小题5】With 固定词组with the help of在…的帮助下
【小题6】 importance 作为动词realize的宾语使用名词形式。
【小题7】determined 固定词组be determined to do sth下定决心做某事
【小题8】.(should)read 考查虚拟语气suggest(建议)后面的句子使用虚拟语气（should）+动词原形。
【小题9】told 本文的主体时态是过去时。
【小题10】such progress是不可数名词，用such修饰名词。
