本影片所學為時間子句-Before and After，透過閱讀搭乘雲霄飛車時需遵守的規則帶入課程，介紹before用來連接兩個不同的事件，代表的意思為在…之前。句型架構是Event 1(先) before Event 2(後)，句子中Event 1先發生，Event 2為後來發生的事件，例如Please put your bag in the locker before you enter the gate 。此外，影片中也介紹以Before開頭的句子架構Before(在…之前) Event 2(後), Event1(先)，如Before you enter the gate(後), please put your bag in the locker (先).。當學生認識before的句型用法後，再學習after表達的意思是在..之後，所屬的句型架構為Event 2(後) after Event 1(先).。在after的句型中後句的Event 1為先發生的事件，前句的Event 2則是後來發生的事件，例如Please buckle up (後)after you get in the car.(先)。以及介紹After為首的句型架構After Event 1(先), Event 2.(後)，例如After you get in the car (先), please buckle up.(後)。 影片中與before有關的例句包含：Before we enjoy the ride, please read the following rules.／Please line up behind the yellow line before the car comes.／You cannot got in the car before it fully stops.／Enjoy your ride and don't forget your bag in the locker before you leave.；與after有關的例句則有After the car starts to run, you may scream and shout loud, but you cannot leave your seat during the trip.
