② 初中八年级英语所有语法
现在完成时
1.构成
现在完成时是由助动词 have(has)+动词的过去分词构成。助动词说明该谓语是属于现在时范围。它和主语的人称、数要保持一致。过去分词是主要的谓语动词，说明句子的意义。
2.用法
（1）表示动作发生在过去某个不确定的时间，但对现在留下了某种影响和结果。常被just, already, yet 等副词修饰。常与非延续性动词连用。 如：
-Have you had lunch yet? -Yes, I have. I've just had it. 你（已经）吃午饭了吗？ 我刚刚吃过。（现在我不饿了）
（2）表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止，可能仍然在进行。常用延续性动词，常带有for和since（自从）等表示一段时间的状语。
如：He has taught here since 1981. 他自1981年就在这儿教书。（可能还要继续教）
I haven't seen her for four years. 我有四年没见到她了。
(3）表示说话前发生过一次或多次的动作，现在成为一种经验，一般译为汉语“过”，常带有twice, ever, never, three times等时间状语。
如： I have been to Beijing twice. 我去过北京二次。
3．结构
1）陈述句结构：主语＋have( has)（not）+过去分词＋其它。have not=haven’t has not= hasn’t.
2) 一般疑问句结构：Have( Has )＋主语＋过去分词＋其它？
3) 特殊疑问句：特殊疑问词＋have(has) +主语+ 过去分词＋其它？
e.g. He has already finished his homework.
He hasn’t finished his homework yet.
Has he finished his homework yet? --Yes, he has. / No, he hasn’t. / No, not yet.
4.现在完成时的时间状语
1）现在完成时属于现在时范围，故不能和过去的时间状语连用。如: yesterday, last Sunday, in1990, three years ago等。但是，在强调动作产生的后果和影响时，可以和一些表示不确定的时间状语连用。
a. 用副词already和yet。already一般用于肯定句中，yet一般用于否定句和 疑问句中。如：We have already finished our homework.我们已完成作业了。
They haven't finished their homework yet.他们还没有完成作业。
b. 用ever 和never。多用于否定或疑问句中，表示“曾经”或“从未“等。 如：-Have you ever been to the Great Wall?你曾经去过长城吗？
-I have never been to the Great Wall.我从未去过长城。 c. 用表示到说话为止的过去时间状语，如just（刚刚）, before（以前）, up to now（直到现在）/ until now, in the past (few years/ three days 等), so far (迄今为止) recently 等。 例如：I have seen her before, but I can not remember where. 我以前见过她，但记不起在哪里见过。
He has been there three times the last few days. 近几年他去过那里三次了。 d.用包括“现在”在内的时间状语，如：today, this morning (month ,year, term等.例如：-Have you met him today? - No, I haven't. 今天你见过他吗？我没有。
How many times have you been there this year? 今年你去过那里多少次？
2） 现在完成时可以和带有since或for等表示“一段时间”的状语连用,表示动作或状态从某一时刻开始，一直持续到现在。如：I haven't seen him for two years. 但是，像come, arrive, buy等终止性动词不能与表示“一段时间”的状语连用。要用，必须改为“be（在）”等延续性动词来表述。现归纳总结一下由非延续性动词到延续性动词的转换：
arrive → be here begin (start) → be on die →be dead come back → be back leave → be away fall ill (sick, asleep) → be ill (sick, asleep) go out →be out finish →be over put on →wear 或be on get up →be up join →be in / be a member of… open → be open close →be closed go to school→ be a student borrow →keep buy →have catch(a cold)→ have(a cold) get to know →know begin to study → study come to work→ work
如：He has been a soldier for three years.他参军三年了。或He has been in the army for there years. 不可以说He has joined the army for there years.
His father has been dead for two years.他父亲去世二年了。（不可以说has died）
The film has been on for ten minutes.电影已开始十分钟了。（不可以说has begun）
We have studied English for three years. （不可以说have begun） 我们（开始）学英语已三年了。
5. 现在完成时和一般过去时的区别
现在完成时和一般过去时都表示在过去完成的动作。但现在完成时强调的是这一动作与现在的关系。如对现在产生的结果或影响等，而一般过去时只表示动作在过去某一时刻发生，不表示和现在的关系。试比较：
I have lost my new book. 我把新书丢了。（现在还未找到）
I lost my new book yesterday. 我昨天把新书丢了。（昨天丢的，现在找到与否没说明）
6.几点注意事项 （1）have been(to)与have gone( to)的区别：have been(to) 表示“去过某地（现在已经回来了）”，可用于各人称；have gone(to) 表示“去某地了（说话时某人不在当地）”，常用于第 三人称，前者可与once ,never, several times等连用，后者则不能。如：They have been to Beijing twice.他们去过北京两次。 He has gone to Beijing . 他去北京了。 （2）“It is或has been + 一段时间+ since引导的时间状语从句”表示“某人干某事已经多长时间了”。since从句的谓语要用非延续性动词 若动词延续，则译成相反的意思。如：It is two years since his father died. =His father has been dead for two years.他父亲去世已有三年了。 It is two years since his father lived here. 他爸爸不住这儿已有三年了。 （3）终止性动词现在完成时的否定式，已变成一种可以延续的状态，因此可以和表示一段时间的状语连用。如：I haven't left here since 1997.自从1997年以来，我一直没有离开过这儿。 （4）.提问for短语或since状语用how long。
(5).完成时的否定形式与比较级连用表达最高级含义。如：
I have never seen a better film.我从未看过一部更好的电影。（这部最好）
注：否定式与比较级连用表示最高级含义不一定用于完成时态。如：
--- What about going fishing? --- I can’t agree more.(我再同意不过了哦)
.语法—直接引语变间接引语（多数情况下变为宾语 从句）
(1). 直接引语如果是陈述句，变为间接引语时，用连词that 引导（口语中可以省略引导词）宾语从句。把下列句子变为间接引语或直接引语：

_______________________________________________________
c. They said they would meet at 9:00 p.m. that night.

____________________________________________________.
b. “Tell me the news, please.” Li Hui said to me.
____________________________________________________.

“_______________________________，” he said to me.
(5).直接引语如果是否定型祈使句，变为间接引语时，谓语变为tell sb.not to do 或ask sb. not to do等。把下列句子变为间接引语或直接引语：a. “Don’t smoke in the room,” he said to me.
________________________________________________.
b. “Don’t shout at the old man,” I said to him.________________________
