1中的kept不是過去時,是動詞的過去分詞,在這里與are構(gòu)成被動語態(tài).
2中have 與been構(gòu)成過去完成時.是一種常見的時態(tài).
Most tower clocks are still kept in Europe.Some of them have been 400 or 500 years old.
Most tower clocks are still kept in Europe.Some of them have been 400 or 500 years old.
1.Most tower clocks are still kept in Europe.這句中為什么are是一般現(xiàn)在時,但后面的kept卻是過去式?
2.Some of them have been 400 or 500 years old.這句中為什么have是一般現(xiàn)在時,但其后的been 是過去式?可否將這句改為--Some of them have 400 or 500 years old.
