Then ask if someone with a preposition flashcard can make a sentence including both the noun flashcard and the preposition flashcard. 然后问哪位拿着介词动画卡片的同学能够造一将这名词和介词都能用上的句子。
A flashcard or flash card is a set of cards bearing information, as words or numbers, on either or both sides, used in classroom drills or in private study. One writes a question on a card and an answer overleaf. Flashcards can bear vocabulary, historical dates, formulas or any subject matter that can be learned via a question-and-answer format. Flashcards are widely used as a learning drill to aid memorization by way of spaced repetition.
