    (1) 表示从过去开始的某个动作刚刚完成或结束，这时常与副词just连用。例如：
    I have just finished my paper. 我刚刚写完论文。
    (2) 现在完成时总是与现在有密切的联系，表示过去开始的动作现在有了结果。例如：
    —Is Sally here?
    —No, she has gone to the library. (她现在已不在这儿了)
    She told me her telephone number but I've forgotten it. (我现在已不记得了)
    (3) 现在完成时常用于提供新的信息或告知最近发生的事情。
    This road is closed. There has been a terrible accident. 这条路被封了。这儿发生了一起重大事故。
    It is reported that the police have caught two robbers in the bank. 据报道警察在银行里抓到两名抢劫者。
    (4) 表示从过去开始的动作持续到现在，甚至延续到将来，常与recently, so far, in the last / past two years, since, for等连用。但短暂性动词不能与它们连用。例如：
    Have you heard from your parents recently? 你最近收到父母的来信了吗？
    I haven't eaten anything since breakfast. 早饭之后，我一直什么东西都没吃。
    (5) 现在完成时与表示始于过去持续到现在的一段时间连用，如：today, this week, this year, these days等。例如：
    This is the best film I've seen this year.
    It hasn't rained this week.
    I've done a lot of homework today.
    I've been very busy these days.
    (6) gone to与been to的区别。例如：
    Kate is away on holiday. She has gone to Europe. (凯特现在或在欧洲，或在去欧洲的途中)
    Kate is back from holiday. She has been to Europe. (凯特已经从欧洲归来，现在不在欧洲)
