If his itinerary hasn't changed, which it frequently does, the president's flight arrives in Rome in two hours.

Q 1 . If his itinerary isn't changed...or hasn't changed...or hasn't been

Q 2 . 如果前面If 子句用完成式( hasn't changed....or hasn't been changed), 後面用 arrive ( 以現在式代替未來) , 正確嗎 ?

Q 3 If 表條件 或 假設語氣 如何區分?

Q4 . the president's flight 用主動 arrive , 適合嗎 ?

    Q 1 . If his itinerary isn't changed...or hasn't changed...or hasn't been

    changed....? which one is correct?

    都對,指是要表的意思不樣.

    "if his... isn't changed" 表示簡單的事實.

    "... has'n changed..."表示對已經更改的推測.

    ".. hasn't been changed..."是用第二句的被動型態 若不是與"which it frequently does"不配合的話,應該也是可以的.

    Q 2 . 如果前面If 子句用完成式( hasn't changed....or hasn't been changed), 後面用 arrive ( 以現在式代替未來) , 正確嗎 ?

    是正確的. "in 2 hours"已經表現出未來時式了.

    Q 3 If 表條件 或 假設語氣 如何區分?

    有差別嗎?.

    Q4 . the president's flight 用主動 arrive , 適合嗎 ?

    是正確的. 航班本來就可以用主動.所有事物 好像有自由意志的 都可以用主動. 連地球,氣球,皮球,眼球,要求 都可以主動.
