31、een to Beijing? 模块四语法现在完成时态(三)1如果要表达某一行为或状态从过去某时间一直持续到现在，则要用现在完成时态。这时，句子通常要与表示一段时间的时间状语连用，这类状语通常由for或since来引导。需要注意的是， for _后面接一段时间，而 since 后面接时间点或过去时态的句子，即 for_ 用来说明动作延续的时间长度，since用来说明动作的起始时间。例如：I have lived in Hebei for ten years. 我在河北已经住了十年。He has been in this school since 2000. 自从2000年起，他就在这所学校了。

32、My sister has learnt English since she was four. 我姐姐从4岁起就开始学英语。2如果要对现在完成时态句子中的时间状语进行提问，通常要用 how long。例如：How long have you studied English? 你学英语学了多长时间了？For four years. 四年了。How long has he taught here? 他在这儿教书多长时间了？Since five years ago.自从五年前。3在现在完成时态的句子中，短暂性动词一般不能与时间段连用，但在 否定句 中，则一般可以和表示一段时间的for短语连用。例如

33、：I have stayed in the hotel for a week. 我已经在这家宾馆待了一周了。My parents havent seen me for two years. 我父母有两年没见我了。He hasnt come to school for a week. 他一周没来上学了。注意 短暂性动词不能和表示一段时间的时间状语连用，但如果要保留表示一段时间的时间状语，必须将短暂性动词改为延续性动词。常见的短暂性动词转换为延续性动词如下(1)fall asleepbe asleep (2)begin/startbe on(3)buyhave (4)diebe dead (5)c

34、omebe in(6)arrivebe here(7)joinbe in/be a member of(8)finish/endbe over(9)leavebe away(10)borrowkeep (11)begin to studystudy (12)come backbe back4现在完成时态还经常用于“Its the first/secondtime that”结构中。例如：Its the first time that I have visited here. 这是我第一次参观这里。It will be the third time that you have seen the

It_ five years since we met last time.Awas Bwere Chas been Dhave been解析 C考查现在完成时。句意：“很长时间没见了！”“自从上次我们见面五年了。”since是现在完成时的标志

36、词，前面主语是it，故用has been，选C()3.Our foreign teacher Mr Green_ us English since three years ago.Ahas taught Bis teaching Ctaught Dteaches()4.Weve lived here _ 1980. So youve lived here _ more than 30 years.Asince; for Bfor; since Cfor; for Din; since解析 A1980是一个时间点，所以用since; more than 30 years是一个时间段，要用for。

37、故选A。()5.2014安徽Rick has learned a lotabout Chinese culture _ he came to China.Abefore Bwhen Cuntil Dsince解析D考查连词的用法。句意：Rick已经学了许多中国文化 _他来到中国。before意为“在之前”；when意为“当的时候”；until意为“直到”；since意为“自从”。since引导过去时态的时间状语从句时，其主句用现在完成时。故选D。()6._ have you learned Chinese? For 3 years.AHow often BHow much CHow long

38、DHow soon解析 C由答语“For 3 years.”可知，上句是问“多长时间”，故选C。()7.Mr Green _ from his home town for 3 years.Ahas been away Bhas gone Chas left Dhas come解析 A句中“for 3 years”是一个时间段，因此要与延续性动词连用，故选A。()8.2015乌鲁木齐Mr Brown_his home town since he_the army.Ahas left; joined Bhas been away from; has joined Chas been away fr

39、om; joined Dleft; joined 解析 C考查动词的时态以及延续性动词与非延续性动词的辨析。since引导的状语从句的谓语是非延续性动词的过去时，主句的谓语动词应用延续性动词的现在完成时。leave是非延续性动词，不能和一段时间连用。be away from是延续性动词，可以和一段时间连用。所以选择答案C。()9.He _ for ten years.Ahas been married Bmarried Cgot married Dhas married()10.How long has Robert _？ Since 2004.Abeen to Beijing Bbecome
