【形式：先生への正式メール】 佐々木先生 いつもご指導いただき、ありがとうございます。1年の伊藤です。課題について質問があります。教科書の20ページを読んだのですが、例文の意味がよく分かりません。お時間のあるときに、説明していただけませんか。よろしくお願いいたします。 (English: A student asks a teacher a question politely.)
In the written piece, identify the grammatical error in this sentence: 「説明していただけませんか。」
- 誤りはない (correct answer)
- 助詞「を」が必要
- 動詞は命令形にする
- 過去形に直す
Explanation: This question tests AP Japanese Language and Culture skills, specifically the use of standard conventions of written Japanese language. The use of standard conventions in written Japanese includes recognizing grammatically correct polite request forms. Understanding that correct grammar can exist within formal contexts helps students avoid hypercorrection. Choice A is correct because 誤りはない (there is no error) - the sentence '説明していただけませんか' is grammatically correct as a polite request using the potential form of the humble receiving verb. Choice B is incorrect because the sentence already contains the appropriate particles and doesn't require を, as いただく takes が or no particle for the object being received. To help students: Practice distinguishing between actual errors and correct formal expressions that may seem unusual. Create exercises focusing on the correct use of giving/receiving verbs in polite requests.
