In recent years, going abroad for a holiday has almost become a national pastime.

最近幾年, 到國外度假幾乎已成為一種全國性的休閒活動。

上列句中, in recent years為表『最近幾年』的時間副詞片語, 與現在完成式has almost become並用。

凡句中有in recent years/months (最近幾年/幾個月) 的時間副詞片語出現時, 常與現在完成式或現在完成進行式並用; 表示到現在為止仍在繼續的動作或狀態時, 使用現在完成式來表達; 表示一直持續到現在且可能仍將繼續下去的動作時, 則使用現在完成進行式來表達。

例: In recent months there have been several demonstrations
　  in that area.

　  (最近幾個月那個地區有過數次的示威活動。)

　  In recent years the economy has been getting worse.

　  (最近幾年，經濟愈來愈走下坡。)

注意:

a. 在英文中, 鮮少使用in recent days, 而用recently、lately、of late來表示『最近』之意, 且亦與現在完成式或現在完成進行式並用; 而使用recently時, 亦可與過去式並用。

例: Recently business has been very good.

　  (最近的生意很好。)

　  Lately it has been getting colder.

　  (最近天氣愈變愈冷了。)

　  Recently John quit his job.

　  (最近約翰把工作辭了。)

b. 表未來的『最近』時, 則用soon或in the near future來表示, 此時時態須用未來式。

例: I will go to see you soon.

　  (我最近會去看你。)

　  The education system will change in the near future.

　  (教育制度在最近的未來將會有所改變。)
