You could almost imagine that you were in Denmark. nearly:表示“几乎，接近，差不多”，常用于被very, not, pretty修饰时 e.g. There is not nearly enough money to buy a new camera. 5. voyage, journey, trip, tour 易混词 辨析 例句 voyage 指“海上旅行”或“航行” Columbus voyaged across the Atlantic Ocean in 1492. travel “旅行”的总称，是不可数名词，其前不加冠词。 Travel in the mountains can be slow and dangerous. journey 指长途陆路旅行，特指“旅途”本身。 It’s a long long journey Till I know where __________________________________________________ __________________________________________________ I’m supposed to be trip 指短途短期旅行，一般为往返旅行。 They made a trip to the lakeside last weekend. tour 指“团队”观光旅游。也可表示“巡视”“巡回比赛”或“演出”。 The band is on tour in China. 6.because of (1)because与because of because为连词，后接从句 because of为介词短语，后接名词、代词或动名词 (2)引导原因状语的介词短语： owing to, due to, on account of, as a result of (3)because, why与that引导的表语从句辨析 a. because表示一种动作或状态的根本原因。 b. why虽然译成“因为”，但实质上表示结果。 c. that引导的表语从句表示原因，主语通常是reason或what引导的主语从句。在the reason why…is/was that…结构中，也只能用that引导。 e.g. He loves her because she is pretty.
