我們用一般進(jìn)行時(shí)來描述事實(shí)或者是習(xí)慣。 如果你正在做什么,那么就可以用現(xiàn)在進(jìn)行時(shí) (am + 動(dòng)詞 + ing)。 現(xiàn)在完成進(jìn)行時(shí), 這個(gè)時(shí)態(tài)可以用來描述一個(gè)在過去開始但還在進(jìn)行的事情,或者是在現(xiàn)在有了結(jié)果,e.g. 'My legs ache because I've been running at the gym.' 如果我們說的是 'How many times...?' 那么強(qiáng)調(diào)的是到講話時(shí)為止已經(jīng)完成的動(dòng)作,所以應(yīng)該使用現(xiàn)在完成時(shí),e.g. 'How many times have you missed class?' 你沒有選擇回答。 |
