You wont pass the exam unless you study harder. ;(4)现在进行时 ;(5)过去进行时 ;(6)现在完成时 ;注意： ①for, since for＋一段时间。例如： I have worked here for a year. since＋过去的时间点/一般过去时的句子。例如： I have worked here since a year ago/since 2016. I have worked here since I came here last year. Its been/Its ＋一段时间＋since＋句子(一般过去时)。例如： Its a year since I worked here. ;②already, yet already 已经(用于肯定句，放句中或者句尾)。例如： I have already read the book. yet 还(用于否定句和疑问句，放句尾)。例如： I havent read the book yet. ;③have/has been to, have/has gone to, have/has been in have/has been to 曾经去过某地(已返回) have/has gone to 去了某地(还没回) have/has been in＋一段时间 去或来到……(一直待在那儿)， 例如： —Have you been to Beijing? —I have been there twice. —Where is Jim? —He has gone to the library. My uncle has been in Shanghai for a week. ;④短暂性动词不能和表示一段时间的状语(for, since, how long)连用。有些动词如come, go, arrive, leave, borrow, die, buy, join, begin, start, end等，它们不能和表示一段时间的状语连用在现在完成时态中。可以通过三种方法： 第一改用一般过去时。 第二改变动词，把这些短暂性动词改变成相对应的延续性动词，与表示一 段时间的状语连用在现在完成时态中。 第三改用句型“It is＋一段时间＋since＋句子(一般过去时)”来表示。 ;短暂性动词与延续性动词之间的转换： come/go/arrive—be(in)　leave—be away from　borrow—keep die—be dead　buy—have　join—be a…/be in…　open—be open begin/start—be on　end/finish—be over　close—be closed ;例如：a.电影已经开始十分钟了。 The film began ten minutes ago.＝The film has been on for ten minutes. ＝Its ten minutes since the film began. b．这只狗死了两天了。 The dog died two days ago.＝The dog has been dead for two days. ＝Its two days since the dog died. c．这辆自行车他买了三年了。 He bought the bike three years ago.＝He has had the bike for three years. ＝It‘s three years since he bought the bike. ;1. —I called you at 4:00 yesterday afternoon, but no one answered. —Sorry, I _____ with my friends at that
