Question

I have been ______ English _______ ten years.
A. study; for      B. studying; since      C. studying ; for   

Answer 1

C

考查現(xiàn)在完成進(jìn)行時(shí)。句意“我學(xué)英語已經(jīng)學(xué)了十年了�！庇锌赡芾^續(xù)學(xué)習(xí)下去，故用現(xiàn)在完成進(jìn)行時(shí)，即have been doing sth.句型。Since不能加一段時(shí)間，for可以加時(shí)間段，故選C。
