I have been studying computer for several years and I still )参考答案am ,
英语语法题8(括号内是错的)
have been doing 现在完成进行时.表示从过去某时开始一直持续到现在的动作,并且还将持续下去.
"I have been studying computer for several years"的意思是我已经学了几年计算机知识.
"and I still am"是个省略句,全句应该是"and I still am studying computer",意思是我现在仍然正在学习计算机.因为有个"still"说明目前仍然在学,后面就应该是现在进行时.
