for the first time在句子中可以作状语表示首次，那样the first time也可以吗？譬如 I come here for the first time.中这个for 可以省略吗？
the first time+从句这个从句可以理解为状语从句或者定语从句吗?
the first time+that或者when，其中that是关系副词等于when的使用方法那样that和when可以省略吗？
不同the first time+从句，是状语从句还是先行词是time的定语从句的办法是看句子成分譬如The last time i saw Jonathan was Thursday evening 这句话中The last time是主语那样后面的一定是省略that或者when的定语从句，我这么剖析是不是正确呢？ 感谢各位专家的解答！
1. for the first time在句子中可以作状语表示首次，那样the first time也可以吗？譬如 I come here for the first time.中这个for 可以省略吗？
【答】for the first time 是一个独立用的介词词组，在句中作时间状语。for 不可省略或漏掉。
2. the first time+从句这个从句可以理解为状语从句或者定语从句吗?
【答】the first time 有两个作用与功效：
（1）直接用作连词，引导时间从句。由名词time 构成的连词总结：
the time, the first time, next time, any time, every time，each time, the last time, from the time, by the time 等，都可以作连词用，引导时间状语从句。
The first time I climbed onto the wall, I felt nervous.
我首次爬到墙上去时，感到胆怯。
Every time I catch a cold, I have pain in my back.
我每次感冒背就痛。
Any time you come to London do look me up.
你无论什么时间到伦敦来，必须要来看我。
I recognized you the minute I saw you.
我一见你就认出了你。
Next time you come, you will see the scientist.
你下次来时就会见到那位科学家。
You may come back any time you want to.
你想回来随时可回来。
Each time the tourist traveled by boat he got seasick.
这位旅客每次乘船行时都晕船。
The last time she saw James, he was lying in bed.
她最后一次看詹姆斯时，他躺在床上。
The truck will have arrived by the time you have all the things packed up.
到你把所有东西都捆好时，卡车也就来了。
（2）用于以下结构：
It is the first time that...
It was the first time that...
例句：
It is the first time that Mr Smoth has visited China.
It was the first time that Mr Smoth had visited China.
【结构剖析】
1. It is the first time 为主句，that Mr Smoth has visited China 为定语从句，修饰the time，that为关系副词，可以省略。因此，大家常说：It is the first time Mr Smoth has visited China.
2. 常见的变式：This is the first time that ...
【时态剖析】
1、It is the first time that...跟与“目前完成时”连用，体现了“目前完成时”的另一个特点：用来表示“人以前的历程”。意味着“从过去某个时间到说话时的历程总结”，也会是人一生所历程，这跟目前完成时的“动作发生在过去，但对目前产生影响”有关，强调次数和历程。比如：
It is the first time...举例：
It is the first time that Mrs Obama has given her approval to the work of a single company.这是奥巴马夫人首次对一个独立企业的工作给予称赞。
It is the first time that we have talked about this issue face to face.这是大家首次面对面地谈论到这件事情。
It is the first time that I have received your letter.那是我首次收到你的来信。
It is the first time that he has performed on such a big stage.这是他首次在这样大的舞台上表演。
It is the first time that she has ever lived in a city in her entire life.这是首次她完全的生活在城市里。
It is the first time that I have been invited to attend such an important meeting.这是我首次被邀请参加这么要紧的会议。
This is the first time...举例：
This is the first time in my life that I have taken part in such a grand celebration.这是我有生以来首次参加这样盛大的庆典。
Although it is not an official Olympic event, this is the first time thatWushuhas come so close to the Olympics.虽然这不是官方奥运比赛，但这是首次武术距离奥运这么近。
But this is the first time that we’ve been able to look at everything.但这是大家首次看到全景。
This is the first time that he has written in English.这是他首次用英语写作。
It is the first time that China has objected to manoeuvres in the area.这是中国首次反对在此地区举行的军事演习。
That is the first time...举例：
That is not the first time that the earthquake potential of a fault has been underestimated.这并非首次低估地震的潜力。
That is the first time they have experienced that.这是他们首次历程那件事。
2、同理，It was the first time，主句用“一般过去时”，那样从句应当用“过去完成时”，体现“过去的过去”这个语法特点：表示“截止到过去某个时间之前的动作历程”。比如：
It was the first time that she had sung in public.
那是她初次公开演唱。
It was the first time that she had lived independently.那是她首次独立生活。
It was the first time that he had wept in nineteen years.那是他19年来首次流泪。

This was the first time I had been treated with such respect.我是首次遭到如此的礼遇。
She was astonished; this was the first time she had heard of such things.她大吃一惊；她首次听说过如此的事。
This was the first time I had seen such a lot of snow.我首次见过这么大的雪。
3.the first time + that或者when，其中that是关系副词等于when的使用方法那样that和when可以省略吗？
【答】the first time 假如用作连词，依据简练原则，之后一般不加关系副词that 或when。比如：
The first time I climbed onto the wall, I felt nervous.
我首次爬到墙上去时，感到胆怯。
在It/This/That is the first time 结构中，that 可以省略。前面有解说和例句：
It is the first time 为主句，that Mr Smoth has visited China 为定语从句，修饰the time，that为关系副词，可以省略。因此，大家常说：It is the first time Mr Smoth has visited China.
4. 不同the first time+从句，是状语从句还是先行词是time的定语从句的办法是看句子成分譬如The last time i saw Jonathan was Thursday evening 这句话中The last time是主语那样后面的一定是省略that或者when的定语从句，我这么剖析是不是正确呢？
【答】“首次” 和 “在星期四晚上”，两个定义不等对。需要在Thursday evening 之前加介词on。
The last time （主语）I saw Jonathan （定语从句）was （系动词）on Thursday evening.（表语）
