which定语从句which做主语

coming某种与老化相关的化学物质的降低

were虚拟语气,如果发现存在某种特殊的生化衰减是根本原因,那么我们就能do it ： produce a drug

decay生化衰减,由于前面提到化学物质的降低,所以没选error选decay.我起先觉得是error（第一语感）,后头也提到了 error accumulation in DNA molecules,但并不是十分确定,.

finding

however

cause但是找到治疗方法的几率/机会取决于是哪种根源（直译）

treatment 6-8题比较明显

and表并立关系,防止自由基的破坏和分离了分子结构（但自由基没有破坏）

but前面提到不难想象,but表转折说如果是DNA分子的误差积累,就很难阻止了.

第4,9题不是很确定.不知道分析对不对.
