v.提到;說到Really?Sowhendiditbecomepopular?Around1917.1.Well,youdoseemtohaveapoint…

嗯，看來你說的確實有道理……

這句話中的助動詞do放在動詞seem前面主要用來加強語氣，通常可譯作“的確，確實”。在謂語動詞前添加助動詞do表示強調(diào)的用法常見于肯定句和祈使句中。在英語中，haveapoint通常指某人的說法或想法“有道理”。如:Perhapsyouhaveapointthere,buttheproblemisthatwedon’thaveachoice.也許你說的有道理，但問題是我們沒有選擇。2.Theyareusedforseeinginthedark.beusedfordoingsth.表示“被用來做某事”。與beusedtodosth.
