中考复习：动词时态
-by Li Na;考点一 动词的分类;动词的分类;;;;;考点二 动词的时态;(1)一般现在时
;(2)一般过去时
;(3)一般将来时
;注意：①短暂性动词的现在进行时表将来。常用词有come, go, arrive, leave等。例如：
The bus is coming.He is leaving for Shanghai tomorrow.
②在when,not--- until, if, as soon as, unless 等引导的时间或条件状语从句中，从句要用一般现在时表将来。例如：
I will come to see you if I have time this Sunday.
You wont pass the exam unless you study harder.
;(4)现在进行时
;(5)过去进行时
;(6)现在完成时
;注意：
①for, since
for＋一段时间。例如：
I have worked here for a year.
since＋过去的时间点/一般过去时的句子。例如：
I have worked here since a year ago/since 2016.
I have worked here since I came here last year.
Its been/Its ＋一段时间＋since＋句子(一般过去时)。例如：
Its a year since I worked here.
;②already, yet
already 已经(用于肯定句，放句中或者句尾)。例如：
I have already read the book.
yet 还(用于否定句和疑问句，放句尾)。例如：
I havent read the book yet.
;③have/has been to, have/has gone to, have/has been in
have/has been to 曾经去过某地(已返回)
have/has gone to 去了某地(还没回)
have/has been in＋一段时间 去或来到……(一直待在那儿)，
例如：
—Have you been to Beijing?
—I have been there twice.
—Where is Jim?
—He has gone to the library.
My uncle has been in Shanghai for a week. ;④短暂性动词不能和表示一段时间的状语(for, since, how long)连用。有些动词如come, go, arrive, leave, borrow, die, buy, join, begin, start, end等，它们不能和表示一段时间的状语连用在现在完成时态中。可以通过三种方法：
第一改用一般过去时。
第二改变动词，把这些短暂性动词改变成相对应的延续性动词，与表示一
段时间的状语连用在现在完成时态中。
第三改用句型“It is＋一段时间＋since＋句子(一般过去时)”来表示。
;短暂性动词与延续性动词之间的转换：
come/go/arrive—be(in) leave—be away from borrow—keep
die—be dead buy—have join—be a…/be in… open—be open
begin/start—be on end/finish—be over close—be closed
;例如??a.电影已经开始十分钟了。
The film began ten minutes ago.＝The film has been on for ten minutes.
＝Its ten minutes since the film began.
b．这只狗死了两天了。
The dog died two days ago.＝The dog has been dead for two days.
＝Its two days since the dog died.
c．这辆自行车他买了三年了。
He bought the bike three years ago.＝He has had the bike for three years.
