2024年12月英语四级语法系统复习:first与at first
first与at first使用方法不同解析:
1、从词性上看不同
first可用作形容词或副词,有时还可用作代词;而at first作为介词短语,只起副词用用途。如:
First class is the most expensive way to travel. 坐头等舱是最贵的旅游方法。
This is the first time I have heard of such things. 这是我首次听到如此的事。
You needn‘t read the whole book hut you must readthe first four chapters.你们不必把整本书全读完,但需要读完前四章。

His second suggestion was not much better than his first. 他的第二个建议比第一个好不了多少。
At first we used hand tools. Later we had machines. 开始大家用手工工具,后来大家有了机器。
2、从使用方法上看不同
1).first的使用方法
first 用来讲明顺序,意为“先……”,暗示接下去还有其他动作或事件要发生,因此其后总是接有then,next,last 等词。如:
Think first, then act. 先想了解再行动。
I‘ll have to finish my homework first. 我得先把作业做完。
Firstboil some water. Thenwarm the teapot. Thenadd three teaspoons oftea. Next,pour on boiling water… 你先烧些开水,然后把茶壶烫热,接着放三勺茶叶,随后冲入开水……
John came home from work. First he read the paper for a while, then he got up from the chairand turned on the radio. 约翰下班回家,先看一会儿报,然后从椅子上站起来,打开收音机。
2). at first 的使用方法
at first 的意思是“起初”“开始”,它主要用于强调前后对照,暗示接下去的动作与前面的动作不同甚至相反,因此常有 but,afterwards,soon,at last等相呼应。如:
At first I didn‘t want to go, but I soon changed my mind. 我开始不想去,但我非常快就改变了主意。
The work was hard at first, but I got used to it. 起初这活儿非常累,不过后来我习惯了。
At first they were very happy, but then things started going wrong. 起初他们生活得非常幸福,但后来就开始出问题了。
At first I paid little attention, but slowly my interest awoke. 起初我没如何注意,但渐渐产生了兴趣。
3、其他什么时间不同
1). at first 除以上使用方法外,其他场所一般不需要它;而first除表示“先……”外,还可表示“最早”“首次”“第一”等。如:
Ladies first. 女性优先。
That‘s mine—I saw it first. 那是我的,是我先看见的。
When did you first meet him? 你首次见他是什么时间?
2). 有时at first并不是固定搭配。如:
She was so nice a girl that he fell in love with her at first sight. 她是如此好的一个女孩,使他一见钟情。
She could tell at first glance to which class a man belonged. 她一眼就能看出一个人是什么阶级。
3). at first与at last不是一对反义词组,后者的意思是“终于”“最后”。如:
At last the truth became known. 最后真相大白了。
She has at last got everything ready. 她最后把所有筹备好了。
At last the bus came. I had been waiting for half an hour. 最后公共汽车来了,我已等了半小时。
