to do成分分析
The behavioral sciences have been slow to change partly because the explanatory items often seem to be directly observed and partly because other kinds of explanations have been hard to find. 其中 to change做什么成分.to find做什么成分.
行为科学之所以发展缓慢,部分原因是用来解释行为的依据似乎往往是直接观察到的,部分原因是其他的解释方式一直难以找到.
be slow to 缓慢地
be hard to 难以做,很难做
to do 做状语
再问: 两个to do都是做状语成分吗?
再答: 是的哦!!!!!!!!
