1. A
翻译:我本可以准时赶上会议,但是因为大雾我们的班机延时了.
解释:B为过去完成时,表明be delayed这个动作发生在另一个过去的时间/动作之前.
但是题中并没有另外一个发生在be delayed动作之后的时间/动作啊.
前句的could have arrived...只是一个虚拟的用法,并不是一个真正发生在过去的动作.而且正是因为此种用法表明是对过去动作的虚拟,才表明选项动作是发生在过去,所以用一般过去时.

2. A
解释:逗号后面的非限制性定语从句中,in which = in the speech
但是she shared with us的后面 ___ it took to be successful in life是一个表示sth的宾语,即和前面构成 share sth with sb 的搭配.
因为这个sth 是一个较长的宾语从句,所以上述短语变成了:share with sb sth.
而这个宾语从句中,took后面又明显缺少一个表示sth的宾语,所以只能用疑问代词what代替了.
BC是副词,在宾语从句中只能充当状语,而不能充当宾语,排除;
that引导的宾语从句,则表明that在从句中只起引导作用,并不充当任何成分(即该宾语从句不缺少任何成分),所以D也错误.

1. had been delayed 是发生在过去的过去 也就是发生在过去一件事之前!所有的过去完成时都这样
2.what 是做宾语就像 I like what I say

1. 这道题有点迷惑人,有可能会看成虚拟语气选B,但是如果选B的话后半句应该是 if the conference hadn't been delayed 或者是其他神马神马的,但是这里有了一个but ,两句就够不成虚拟从句的关联,所以选A就可以了,不用想太多。
2.这种题,首先要看从句缺不缺成分,这道题里的从句 it took to be successful in life 明显在to...

1. 这道题有点迷惑人,有可能会看成虚拟语气选B,但是如果选B的话后半句应该是 if the conference hadn't been delayed 或者是其他神马神马的,但是这里有了一个but ,两句就够不成虚拟从句的关联,所以选A就可以了,不用想太多。
2.这种题,首先要看从句缺不缺成分,这道题里的从句 it took to be successful in life 明显在took后缺少了宾语,是名词性从句,所以选A。 这个方法比较快且好用。

答:1. but引出的是过去发生的实际情况,用一般过去时。如果用if,虚拟条件句,则用过去完成时,不过是相反的假设:If our flight had not been delayed ..., I could have arrived on time ...
这个可以是看作省略了或隐含了虚拟语气条件句,
译:我本来是能够准时参加那个会议的 (如果我乘的那次航班不是因为雾大而延误的...

译:我本来是能够准时参加那个会议的 (如果我乘的那次航班不是因为雾大而延误的话)可是我乘的那次航班因为雾大而延误了。 if 从句和but句,只要其中一句,就能表达自己的意思了。当我们用if 从句时,括号中也可以加一句(可是,实际上。。。)
2. share sth. with sb.
这里的sth.=名词性从句,因较长,放在了with sb.之后。
从句还原:It took XXX to be successful in life. 在生活中要成功,需要XXX。
这XXX是什么(what?),说话者也不知道,或者不想说,所以用what来代替。这就是引导名词性从句的连接代词what,它
相当于一个名词+that-定语从句。意为“要在生活中成功所需要的那个啥”。

第一题:B选项为过去完成时,过去完成时表示过去某一时间或动作以前已经发生或完成了的动作。它表示动作发生的时间是“过去的过去”。通常你能在句子中找到一个发生在这个动作之前的时间或者动作,给个例子
When we got to the cinema, the film had already begun.当我们到达电影院时,电影已经开始了。
第二题:关键在share with这个短语,...

When we got to the cinema, the film had already begun.当我们到达电影院时,电影已经开始了。
第二题:关键在share with这个短语,通常我们见到的完整形式应该是share sth with sb,而这道题应是这种短语的变形,句中缺少宾语,因此后面是一个宾语从句,而宾语从句中take缺少宾语(你想想take有直接跟不定式的么?),宾语从句缺宾语要选what。
