1、caught,陷入一场交通堵塞,肯定是被动的咯。所以用Being。
2、When
taken相当于是when
it
is
taken的省略的用法。
3、dare可以作情态动词,所以就直接加do
sth了,就不用不定式to了。dare
(not)
do
sth是:敢(不敢)做什么。

这是一些现在完成时的资料,你看看吧,希望对你有帮助
讲解如下:
——————————————————————--——-
现在完成时用来表示之前已发生或完成的动作或状 态,其结果的确和现在有联系。动作或状态发生在过去 但它的影响现在还存在;也可表示持续到现在的动作或 状态。其构成: have (has) +过去分词。
现在完成时的基本构成方式是用动词have加上过去分词。它是用来表达过去发生事情的另一种方式。
He has studied English and French
他学习过英语和法语。
I have read many books
我读过很多书。
通常一个动词的过去分词和他的过去式是一样的,但是有一些动词的过去分词有不规则的形式。
be been
go gone
come
come
run
run
swim swum
fly
flown
see
seen
speak spoken
do done
give
given
hide hidden
become become
take
taken
get gotten / got
break broken
shake shaken
wake
waken
awake awaken
rise risen
lay lain
fall fallen
begin begun
know known
forget
forgotten
write written
choose chosen
drink drunk

She has forgotten her name She has amnesia
她已经忘记了自己的名字。她有健忘症。
I have already drunk the coffee
我已经喝过咖啡了。
They have gone to see the President
他们已经去见校长了。
She has come to see you
她来看过你了。
当have被用在现在完成时态中时,它可以和前面的代名词一起组成缩写形式。
I've been to New York once before
我曾经到过纽约。
He's gone to the fish market
他已经去过鱼市了。
We've come to help
我们已经提供了帮助。
现在完成时用not来表达否定形式。当有not出现的时候,have可以和not组成缩写,但是此时不能和前面的代名词组成缩写。
She hasn't spoken to him
她还没和他说过话。
We've not spoken with her
提问的时候,have需要被提到句首。
Have you seen Matthew
你见过马休了么?
简单过去时和现在完成时在一定程度上有共同之处,当然事实上两者之间有本质区别。当需要指明过去一个特定的时刻发生的事情时,需要使用简单过去式。
He finished three days ago
他三天前做完了工作。
They finished a long time ago
他们老早就完成工作了。
当没有特定指明的时间,现在完成时和简单过去时都可以使用。
I have already finished
我早就完工了。
I already finished
我早就完工了。
简单过去时比现在完成时更能表达事情的结果。
John has taught math for twenty years
约翰已经教了20年的数学。
John taught math for twenty years
约翰教了20年数学。
在上面的句子中,第一句保留了约翰继续教数学的可能性。第二句表明约翰已经不再教数学了,他可能退休了,换工作了,或者去世了。
Steve and Carol have eaten at that restaurant twice They really like it
史蒂文和卡洛尔已经在那家饭店吃过两次饭了。他们真的喜欢那里。
Steve and Carol ate at that restaurant twice
史蒂文和卡洛尔两次在那家饭店吃饭。
如果一件事情发生在过去并且延续到说话的这个时刻,就需要使用现在完成时。
They have lived here for a long time
他们在这里已经生活了很长一段时间。
She has been in Australia for two years
她到澳大利亚已经两年了。

下面的句子包含了“动作在过去发生并且已经结束”的含义。
They lived here for a long time
他们在这里住了很长一段时间
Melissa waited for 30 minutes
梅丽莎等了30分钟。
通常当句子里有since时我们使用现在完成时。
We have lived here since June
我们从六月份开始就住在这里。
She has been in China since last month
她从上个月起就在中国了。
当现在完成时前有might时,就算主格是第三人称单数形式,我们还是使用have的动词原型形式。
She might have forgotten to lock the door
她可能忘记了关门。
He might have given the painting to someone
他可能已经把画给别人了。
Should、could、must没有简单过去时他们用现在完成时来表达过去的状态。

我希望你至少要试试看

没有was took
Be动词只能加过去分词形式,就是taken
be+过去分词是被动。
所以have/has been taken 是现在完成时的被动, have/has taken是现在完成时的主动;had been taken 是过去完成时的被动/ had taken是过去完成时的主动。
took一般过去时/taken过去分词。

在英语语法中,不定式是指动词中的一种不带词形变化从而不指示人称、数量、时态的一种形式。
它之所以被称做不定式,是因为动词不被限定,或者说不被词形变化所局限。不定式属于非谓语动词形式。
动词不定式可以作以上各种成分,但它毕竟是动词,所以有动词的属性。
扩展资料动词不定式及其短语还可以有自己的宾语、状语,虽然动词不定式在语法上没有表面上的直接主语,但它表达的意义是动作,这一动作一定由使动者(动词的使用者)发出。
对于英语来说接不定式的单词多为“打算”“计划”“希望”“将要做某事”等表示未来(未做的事)的动词。同样与不定式表示不同,现在分词表示正在进行,一般性或经常性发生的行为。
如果动词不定式的逻辑主语是这个不定式所表示的动作的承受者,不定式一般要用被动语态形式。如:
It's a great honour to be invited to Mary's birthday party(不定式作主语是被动语态to be invited是被邀请)——意思:能被邀请参加玛丽的生日聚会真是太荣幸了。
It was impossible for lost time to be made up(不定式作主语)——意思:
弥补损失的时间是不可能的。
I wish to be sent to work in the country(不定式作宾语)——意思:
我想被派到这个国家工作
