1. 介系词at可表一较为精确的「地点」,例如学校、机构、学术会议或地址等,例如:

at school(在学校)

at California State University(在加州州立大学)

at a conference (在研讨会)

at the 34th Annual TESOL Convention(在第 34 届英语教学年会)

at the following address在以下的地址

 而在写作时若要指示文本中的特定「位置」,用到介系词at的情况有:

at the beginning of this thesis(在此论文的开头)

at the outset of the book(在本书一开始)

at the end of this paper在本文末

at the top/bottom of this page在本页的上下方

再来看看例句

The majority of the students had taken at least one previous composition class at the university.

这所大学大多数的学生之前至少有修过一门写作课。

 Four survey responses came from individuals at two institutions.

有四份调查回应来自于两个机构里的成员。

 His paper was presented at the meeting of the Hawaii Health Research Association.

他的论文发表于夏威夷卫生研究学会会议上。

 Information about the digital images can be found at the bottom of this page.

 2. 介系词at也可用来表达「时间」上的一点,例如:

at 4:00 p.m.(于下午四点)

at times of difficulty(在困难时)

at the age of 20(在 20 岁时)

 

 或表稍长的时段如:

at dawn在黎明

at noon在中午

at night在晚上

 而在写作上用得较多的是与时间相关的词组,其所指涉的时间通常较短,如:

at present/at the present time目前

at the moment(当下)

at the same time(同时)

at that time(那时)

at any given time(随时)

 

请看例句:

At the present time the two countries seem to be moving toward very different conclusions.

目前这两个国家似乎朝向非常不同的结论。

 Only a very few rules can be consciously applied at any given time.

只有少数几条规则是随时能有意识地应用。

 3. 介系词 at 还可用以表达事物的价格、数值、程度和发展阶段等,其所指涉的状态都是相对较为特定的点,例如:

at the price of $300 per box(每盒 300 元的价钱)

at the speed of 60 kilometers per hour(每小时 60 公里的速度)

at the temperature of 1050°C(温度摄氏 1050 度)

at the rate of $400 per person-month (每人每月400美)

at the same pace(相同的步调)

at best至多

at most充其量

at least至少

at this level(在这种程度上)

at this point(在这点上)

at various stages(在各种阶段)

 

例句如下

The mean difference is significant at the .05 level.

平均数的显著性差异是设在 .05 的水平。

Many students have significant spoken language needs at the advanced and professional levels.

许多学生都有进阶和专业程度口语能力的高度需求。

同样用at搭配表「程度」、「级别」level的词组还有at a very high level, at the same levle, at each level, at most levels, at lower levels, at the theoretical level, at the marco-level等。但如果level是表「平面」、「层面」之意,则介系词常用on,如on several different levels(从不同层面)。

 At this stage, the social and political climate should be carefully assessed in light of the results.

有鉴于此结果,在这阶段对社会和政治的气候应审慎评估。

同样用at表达「阶段」的词组还有at each stage, at some stage, at any one stage, at early stages, at a late stage, at a later stage等。

 4. 介系词 at 还可以与其它词类搭配形成惯用语,例如以下常用于论文写作的句子:

The present study was aimed at a reexamination of the question of motivation at the theoretical level.

本研究旨在从理论层次重新检视动机的问题。

动词aimat搭配形成词组动词,其义为「目标在于」,此句型常用于撰写研究目的。

Many studies have arrived at similar conclusions.

许多研究都达至类似的结论。

动词arriveat搭配形成词组动词,其义为「达到」,此句型常用于撰写研究结论。
