• C． When I went to the beach

Answer 1

分析 -你收集貝殼多久了？
-自從我十歲．

解答 答案：D；After I left school在我離開學(xué)校之后；Before I moved here在我搬到這里之前；When I went to the beach當(dāng)我去海灘的時(shí)候；Since I was ten years old，自從我十歲；根據(jù)句中的"How long have you been collecting shells，你收集貝殼多久了"可知答語(yǔ)應(yīng)該是用于完成時(shí)態(tài)的時(shí)間短語(yǔ)，即一個(gè)時(shí)間點(diǎn)；比較上述四個(gè)答案，只有Since I was ten years old是用于完成時(shí)態(tài)的時(shí)間短語(yǔ)，故選D．

點(diǎn)評(píng) 掌握時(shí)態(tài)的正確運(yùn)用是解答該題的關(guān)鍵；還要對(duì)給出的答案進(jìn)分析和比較，從而作出正確解答．
