B.your father retired
how many year ago（注意ago)是問過去的一個確切時間,而不是至今有多少年.
不能用完成時態(tài).
He retired 5 years ago=he retired in 2005
你覺得上面兩句能用完成時態(tài)嗎?
同樣,how many years ago后也應(yīng)該用一般過去時.
另外,how many引導(dǎo)的是一個賓語從句,作wonder的賓語,所以后面不能用疑問句的語序,而是正常語序.
第二題 B.what he said 原因同上,在從句中,不管是什么疑問句都要變成正常語序.
what are you doing?--------he asked her what she was doing.(不是what was she doing)
where are you going?------he asked her where she was going.(不是where was she going)
