If someone asks, “How are you?” and you reply, “Fine,” without really thinking about it, that’s an automatic reply. Something that’s automatic is done without thinking, almost as if you’re a well-programmed machine.
The word automatic can be used to describe a machine that works on its own, performing its tasks with little or no human intervention, such as an automatic transmission on a car. Or, automatic can describe a person whose actions are like a machine's. If you flash a smile every time someone walks through the door, it’s an automatic smile, a natural reaction you didn't think about or plan in advance.
实用短语
常用短语
单词用法
在这组词中,address,speech,talk,oration四个词是同义词,lecture和report的词义与其他四个词的词义差异较大。
①lecture指学术性的“专题讲演”,尤指大学教师讲课,引申义为“教训”。
例如Professor Black will give us a lecture on English literature tomorrow afternoon布莱克教授明天下午将给我们做关于英国文学的演讲。
His mother gave him a lecture for getting up late.他妈妈因为他睡懒觉而训斥了他一顿。
注意这六个词中只有lecture不可与make连用。②report指下级对上级或委托机关的“报告”,比汉语中“报告”的外延小得多。
例如The manager had just given the company?s annual report.经理刚做了公司的年度报告。
2.address,speech,talk,oration四个词的共同含义是“当众讲话”。
其区别是
①speech和talk是普通用语,address和oration是正式用语。
②address和oration用于正式隆重的场合,经过充分准备,听众较多,篇幅较长。这两者中,oration比address更正式,更隆重,人更多,篇幅更长。
例如The minister?s address will be broadcast at8o?clock.部长的讲话将于8时广播。
Lincoln?s Gettysburg Address was an oration林肯的盖茨堡讲演是一篇雄辩有力的演说辞。
这两个词含义上的区别是:address强调演说人的身份或地位高,而oration则强调演说人口才好,演说有煽动性,雄辩有力,词藻华丽。
③speech和talk的区别是speech多用于正式场合,也可用于非正式场合;而talk多用于非正式场合,也可用于正式场合。
speech一般是经过准备的也可不经过准备;而talk一般是不经过准备的。
speech的措辞一般是庄重的;而talk是较为随便的,讲话方式也较自由,甚至也可以是对话。
例如Please tell us what you think in a few simple words,we don?t want a speech.请用简短的话说明你的意思,不要演说。
We enjoy freedom of speech.我们有言论自由。
We had a long talk about it.关于此事,我们作了一次长谈。
He gave us a very interesting talk on Yugoslavia.他给我们作了一场饶有兴趣的关于南斯拉夫的报告。
④speech除作“讲演”解之外,还有“讲稿”“讲演风格”的含义,而另外三个词无此含义。
例如His speech was sent to the newspaper in adv.ance.他的讲话稿事先就送报社去了。
Her speech is informal and filled with colloquialisms.她的讲话常是非正式的,很口语化。
v.(动词)lecture about,lecture on这两个短语都表示“就…作讲演”。其区别在于接about时内容比较广泛,接on时,内容较集中、专一;
