I have been thinking about for purchasing it for a long time .这句话有没有语病

问题描述:

I have been thinking about for purchasing it for a long time .这句话有没有语病

有病,很严重的病
先看你的中文意思,我已经考虑关于买这个东西很长时间了
中文看了都纠结
还有你的about 跟for是什么作用?两个介词?
i have been thinking of buying it for a long time
我已经考虑买这东西很长时间了


应该是thinking about purchasing it

把 for 去掉就对啦
think about doing sth
