Language practice
Grup wrk: read the sentences and summarize the use f the present perfect tense tgether with fr & since.
（1）现在完成时可以表示某一行为或某一状态从过去某一时间一直持续到现在。这类句子通常包含由fr或since引导的时间状语，fr后接段时间，since后接时间点。如：I have lived in Beijing fr 10 years. 我在北京住了10年了。I have been in this schl since 2000. 从2000年起我就一直在这所学校。
现在完成时（三）
（2）用hw lng对现在完成时的时间状语提问。Hw lng have yu played ftball?Hw lng have yu been like this?
表示某一行为或状态持续多长时间时，根据时间的不同，可以使用不同的时态。I stayed in the htel fr a week last summer.I have stayed in the htel fr a week nw.I will stay in the htel fr a week next mnth.
（3）二者可以转换 fr + 一段时间 = since + 一段时间 + ag He has been here fr five weeks.= He has been here since five weeks ag. 他到这儿已经有五个星期了。
since能引导时间状语从句(主句用现在完成时，从句用一般过去时)，而fr则不能。He has taught here since he came t China. 自从他来到中国就在这儿教书。
（5）现在完成时常用句型：①It is (has been) +时间段+ since +时间状语或从句It is fur days since last Friday. 从上周五到现在已经四天了。It has been tw years since Jim came t Beijing.吉姆来北京已经两年了。
②This is the first (secnd…) time that + 从句，句型中的that从句通常使用现在完成时。This is the first time that Jenny and Danny have been t China.这是珍妮和丹妮第一次来屮国。
（6）均须与延续性动词连用，也可以与非延 续性动词的否定式连用。如:I have bught this cmputer since fur years ag. (×)I have had this cmputer since fur years ag. (√)I haven’t bught anything fr tw mnths.(√ )I haven't heard frm him fr 3 weeks. (√)
注意，在现在完成时的句子中，点动词（终止性动词）一般不能与表示延续的时间状语连用。试比较：汤姆已经来了两小时了。(×)Tm has cme fr tw hurs. (√)Tm has been here fr tw hurs.
终止性动词可以和延续性动词进行转换。(1) 转化为“be+形容词/副词等”。 die → be dead leave → be away (frm) pen/clse → be pen/clsed stp → be ver arrive in (at)/reach/get t → be in/at jin → be a member f/ be in start/begin → be n(2) 转化为意思相同的延续性动词。 brrw → keep buy → have becme/cme→be get t knw→knw
常见非延续性动词和延续性动词的转换
leave — be away brrw — keepbuy — have begin/start — be ndie — be dead finish --- be verpen sth — keep sth pen fall ill — be ill
get up—be up, cme here — be here,jin — be n +组织机构 /be a member f + 组织机构,g there — be there, becme — be, cme back—be back, fall asleep — be asleep,
