I remember everything as if it had happened yesterday.
我记得一切事情,好像那些都是在昨天发生得一样.
尽管你说你确定答案是A,但我觉得还是应该选B.
这是as if的虚拟用法.
抓住时间词yesterday,我所记得的事情实际上并不是昨天发生的,所以是虚拟语气,而表示与过去事情相反的虚拟语气中要用过去完成时表示过去时.
as if/though+从句:1.表达与现实或将来相反:使用过去时
2.表达与过去事实相反:使用过去完成时.
分别举例:
1.He looks worried as if he was the murder.
他看起来紧张,好像他就是凶手一样.
2.It is so cold as if it snowed soon.
天气这么冷好像不久就会下雪似的.
3.He sang the song as if he were a singer last time.
他上次唱歌唱得好像一位歌星似的.

答案是A,绝对正确.
as if:
好像

例句与用法:
1. He was shaking with fright as if he had seen a ghost.
他吓得直哆嗦,就好像看见了鬼一样。

2. He quickly ran home, looking as if there was somet...

as if 的用法
as if 好像,好似 She spoke to me as if she knew me. 她和我说话的神情,好像她早就认识我似的。 (= as though)
as if 的用法
一、as if 从句的作用 1. 在look, seem 等系动词后引导表语从句。如: She looks as if she were ten years younger. 她看起来好像年轻了十岁。 It seems as if our team is going to win. 看来我们队要胜了。 2. 引导方式状语从句。如: She loves the boy as if she were his mother. 她爱这男孩,就好像她是他的母亲一样。 The child talked to us as if he were a grown?up. 那孩子跟我们谈起话来,像个成年人似的。 二、as if 还可用于省略句中 如果as if 引导的从句是“主语+系动词”结构,可省略主语和系动词,这样as if 后就只剩下名词、不定式、形容词(短语)、介词短语或分词。如: He acts as if (he was) a fool. 他做事像个傻子。 Tom raised his hands as if (he was going) to say something. 汤姆举起手好像要说什么。 She left the room hurriedly as if (she was)angry. 她匆忙离开房间好像生气的样子。 三、as if 从句的语气及时态 1. as if 从句用陈述语气的情况。 当说话者认为句子所述的是真实的或极有可能发生或存在的事实时。如: It sounds as if it is raining. 听起来像是在下雨。 He talks as if he is drunk. 从他谈话的样子来看他是醉了。 2. as if 从句用虚拟语气的情况。 当说话人认为句子所述的是不真实的或极少有可能发生或存在的情况时。从句虚拟语气动词时态的形式如下: (1)如果从句表示与现在事实相反,谓语动词用一般过去时。如: You look as if you didn’ t care. 你看上去好像并不在乎。 He talks as if he knew where she was. 他说话的样子,好像他知道她在哪里似的。 (2)从句表示与过去事实相反,谓语动词用“had+过去分词”。如: He talks about Rome as if he had been there before. 他说起罗马来好像他以前去过罗马似的。 The girl listened as if she had been turned to stone. 那女孩倾听着,一动也不动,像已经变成了石头似的。 (3)从句表示与将来事实相反,谓语动词用“would/could/might+动词原形”。如: He opened his mouth as if he would say something. 他张开嘴好像要说什么。 It looks as if it might snow. 看来好像要下雪了。

had happened 意思是事情的影响力到昨天已经结束
happened意思是昨天发生,影响力一直在持续没有结束

其实做这类的题目很简单,as if 后面跟的是虚拟从句,如果前面的动词是一般现在时,as if 后面从句的动词就用过去式,如果前面的动词是过去式,as if 后面从句的动词就用过去式完成式,除了特定意境以外。

虚拟语气并不和用不用as if 有关
如果后面跟的情景绝对不可能发生则用虚拟语气,就算前面只有if也是。如if I was a bird

主句是一般现在时,从句只往前推一个时态就可以了
或者你翻译一下,答案就很明显了

主句是一般现在时,从句只往前推一个时态就可以了.这句话的意思是(我记得所有事,好象发生在昨天).如果选B的话,就变成了(好象发生在昨天之前).你自己好好领悟领悟吧

很简单一个问题,yesterday 就是过去时的标志,看到它就用过去时一定对

as if 后接非事实,用虚拟式,表示与现在的事实相反,所以用过去式。
我也没在虚拟语气上下过功夫,加上多年未教这东西,所以说不好,请见谅。
