时态:现在现在完成时(二)

在学习这一概念的同时,还应注意常与现在完成时连用的几个副词:already, just, ever, yet, never等。already, just多用于肯定句中,ever, yet, never多用于疑问句和否定句中。

如:ih**ealreadyfinishedmyhomework.

我已经做完家庭作业了。

hehasjusthadhismeal.他刚吃过饭。

h**eyoueversungthisenglishsong?

你曾唱过这首英文歌吗?

theyh**en’tstartedyet. 他们还没有身。

weh**eneverheardofit.

我们从来没有听说过这件事。

1). h**ebeenin,h**ebeento与h**egoneto 的用法。

h**e (has)beenin意为“已经在某地呆了多长时间”常与表示一段时间的状语连用。

布朗先生来上海已经有三天了。

theyh**ebeenincanadaforfiveyears.他们到加拿大有五年了。

2).h**e (has)beento 意为“曾经去过某地”,表示现在已经不在那里了。可与 just,ever,never 等连用。

如:i’vejustbeentothepostoffice. 我刚才去邮局了。

h**eyoueverbeentohangzhou? 你曾经去过杭州吗?

maryhasneverbeentothegreatwall. 玛丽从未去过长城。

3).h**e (has)beento后面可接次数,表示去过某地几次。

如:i'vebeentobeijingthreetimes. 我去过北京三次。

theyh**ebeentothatvillageseveraltimes. 他们去过那个村庄好几次了。

4).h**e (has)goneto意为“到某地去了”,表示到了某地或正在去某地的途中。总之,说话时该人不在现场,一般不用第。

一、二人称代词作主语。

如: —whereistom?汤姆在**?

—hehasgonetothebookshop. 他到书店去了。例如:

he has gone to hong kong.

他到香港去了。(他已前往香港, 或在途中,

或已到达。说话人暗示他现在不在现场)

he has been to hong kong. 他曾到过香港。

说话人认为他过去到过香港, 现在已不在该地。

言外之意他对香港有所了解)

for 和 since 在现在完成时中的应用。

for与since都能与现在完成时连用,但区别较大:

1)for后须接“时间段”

he has studied english for five years. 他学英语5年了。

2)since后须接“时间点” he has studied english since 1999.

他从2023年开始学英语。

3)二者可以转换

for + 一段时间 = since + 一段时间 + ago

he has been here for five weeks.

he has been here since five weeks ago.

他到这儿已经有五个星期了。

4) 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for则不能。如:

he has taught here since he came to china.

自从他来到中国就在这儿教书。

we h**e been friends since we met in school.

我们从在学校见面起就成为了好朋友。

5)现在完成时常用句型:

it is (has been) +时间段+ since +时间状语或从句。

it is four days since last friday.

从上周五到现在已经四天了。

it has been two years since jim came to beijing.

吉姆来北京已经两年了。

this is the first (second…) time that + 从句。

句型中的that从句通常使用现在完成时。如:

this is the first time that jenny and danny h**e been to china.

这是珍妮和丹妮第一次来屮国。

this is the third time that i h**e seen karen.这是我第三次见到karen。

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 h**e bought this computer since four years ago. (

i h**e had this computer since four years ago. (

i h**en’t bought anything for two months.(√

i h**en't heard from him for 3 weeks. (

非延续性动词和延续性动词的转换。

le**e — be away borrow — keep buy — h**ebegin/start — be ondie — be deadfinish --be over

open sth — keep sth openfall ill — be illget up—be up

come here — be herejoin — be on +组织机构 /be a member 组织机构,go there — be therebecome — become back—be back, fall asleep — be asleepget to/ arrive/reach — be (in),

le**e — be away fromget to know — know,

go (get) out —tie output on—wear,

7)二者引出的时间状语往往用 how long提问。
