* Unit2 Travelling Grammar 2 ▲现在完成时态的含义是表示过去发生的或已完成的动作对现在造成的影响或结果。特点是既涉及过去，又联系现在：动作是过去发生的，结果是现在存在的。 She has gone. (她走了。)从这句话中动词所用的现在完成时态可以看出“走”的动作是过去发生的，而对现在所造成的结果是她不在这里了。 用Have(has)been或have (has) gone填空: 1.My father __________ to Beijing. He will be back in two days. 2.The Greens __________ to the USA twice. 3.A:Where are your parents now? I haven’t seen them for a long time. B:They __________ to Xiamen. 4.Millie __________ to many places of interest in our city. 5.A:_____ Tommy _____ to Nanjing? B:Yes. He went there last month and hasn’t come back yet. has gone have been have gone has been has gone Translate the following sentences. 1.我叔叔已去过美国两次,但我从没去过。 My uncle has been to America twice, but I have never been there. 2.Nick 在哪里？他去了图书馆。 Where is Nick? He has gone to the library. 3.Kitty和爸爸妈妈去了香港，她们一个礼拜之后回来。 Kitty and her parents have gone to Hong Kong. They will be back in a week. -Have you ever seen this film ? -Yes , I ________ (see) it recently . - When ____ you ____ (see) it ? - Last week . have seen did see 完成时表示动作完成 过去时表动作发生具体时间 I lived here five years ago .(同义句) I have lived here since five years ago . I have lived here for five years . 此句中的动词live 是可以延续的， 可以和since+点时间以及for + 一段时间连用。 如果动词是非延续性的，则不可以和since以及for连用 如buy和borrow是非延续性动词，我们在使用时要注意。 我们可以说：I bought a present last week . 但我们不可以说： I have bought a present for one week . I have bought a present since one week ago . 为了和for以及since连用，在使用完成时我们需把非延续性动词转换成延续性。 buy have / has had He has left Beijing for a week. He has not left Beijing yet. He has been away from Beijing for a week. He has bought a car since 2007. √ √ × × He has not bought any new car since 2007. √ He has had a car since 2007. √ 1.buy have (has) had 2.borrow have (has) kept 3.arrive have (has) been in/at 4.leave have (has) been away 5.join have (has) been in /a member of 6.die have (has) been dead 7.get married have
