There are 16 members. 我家是个大家，有十六口人。 类似的集合名词还有army，group, organization, team, nation等。 (2) be on holiday表示状态“在度假”go on holiday表示动作“去度假”。例如： Jack told me that his parents had gone on holiday two days before. 杰克告诉我他的父母亲两天前就去度假了。 One of the most important temples in danger was the one at Abu Simbel.位于阿布辛波的那座寺庙是处境危险的最重要的寺庙之一。 the one，用来代替一个特指的单数可数名词;而one用来代替一个泛指的单数可数名词。例如： The school is that we visited last year.这所学校是我们去年参观过的那所学校。(the one=the school) There were a lot of books in the shop and I bought. (one=a book) 那书店里有很多书，于是我买了一本。(one+ a book) Today you can either fly to Abu Simbel or you can take a boat from across the lake. 今天，你可以乘飞机去阿布辛波，也可以从湖对岸乘船前往。 from across the lake从湖对岸，介词from后面往往可以再接一个介词短语，在句中作地点状语。这一结构也叫双重介词结构 (责任编辑：admin) |
