first of all first the first at first的区别

Question

如题所述

Answer 1

first of all意为“首先”，强调次序。如：

First of all, let me introduce myself to you. 首先，让我作个自我介绍。

first有四个词形：adj. adv. n. pron. 这里主要谈adj.和adv.
first adj. 序数词 第一的
Example: He was the first student who arrived at the classroom.
adv. 首先
First I fed the baby. Then I made myself a sandwich.
at first是一个介词短语在句中充当状语
首先
At first I was nervous, but I soon started to relax.
补充一个firstly 修饰句子的副词 首先
The plan was not practical, firstly because of the cost, and secondly because local people did not support it.
通常可互用，但有差别，需查词典体会。

at first 起先(一般叙述事情,或者故事的时候用)
the first 第一个 ..

Answer 3

这要从它们的用法来区分,若从意思来区分是很白痴的
first不可做时间状语,只可用来修饰其他词,如形容词
at first,放在句首做时间状语,起先,刚开始的意思.
first of all不能做时间状语,用来表示顺序.
