更好的句子应该是：I have to spend more time （in） getting trained,which is the only way to improve my soccer skills.为什么啊。。。。 还有那个which代的是句子还是训练这个事还是说都可以 我有点迷这个一般说，1 根据你的语境，training是名词，不是动词。如果是名词，你的原句应该是：I have to spend more time ON training, which is the only way to improve my soccer SKILLS.2 一般不说improve- - - level-------这多多少少有些Chinglish.instead,比较English的表达是：improve- - -skills。3 spend time on sth spend time (in) doing sth4 which指代I have to spend more time ON training / (in) getting trained.get trained 是不是就是说接受训练 which不能单指代训练这个事嘛对，接受训练。which不能单指代训练这个事嘛当然可以，但语感告诉我，你的句子reads kind of awkward.
