Diction

George was a born leader. 乔治是天生的领袖。
No one is a born slave. 没有人生来就是奴隶。
All men are born the same, and equal. 所有人出生时都是一样的，都是平等的。
2.strike（vt．）可作“给留下深刻印象”解，常用于被动结构。如：
We were struck by the professor’s speech．教授的演讲给我们留下深刻印象。
Everyone was struck with its beauty．它的美丽给大家留下深刻印象。
How does the plan strike you？你对计划的印象如何？
3.短语动词get back相当于return to a former condition，or to a point formerly reached，意为恢复，回复到。如：
He has got his strength back after his illness．他病后体力已经恢复了。
The student was glad to get back to his books after a vacation that had seemed too long．在似乎过于漫长的假期后学生乐于回到书本上来。
get back还可作“回来”（come back），“后退”（move backwards or away），“收回”（gain）解。如：
I never lend books; it’s difficult to get them back．我从不把书借出，很难讨回书。
Get back! The roof is falling！往后退！屋顶要塌了！
He has just got back from his long journey．他长途旅行后已回来。
4.demanding（adj．）意为苛刻的，要求极高的，费力的，在句中作定语。如：
This was a demanding job, but he didn’t refuse it．这是一件费事的工作，但他并未拒绝。
We have to look after the demanding boy．我们不得不照顾那个难对付的孩子。
5.owe（v．）原作“欠钱”，“欠债”解，引申作“欠情”，“感恩”，“感激”，“归功于”解。owe sth．to sb．这一结构表示欠某人某物。如：
I own 50 dollars to him. (= I owed him 50 dollars. ) 我欠他50美元。
We own a great deal to our parents and teachers．我们应对父母和老师感恩戴德。
I own my knowledge of English to my father. (= I own thanks to my father for the knowledge of English．)我的英语知识是父亲教给我的。

Although it started raining, they kept on working．虽然开始下雨了，他们仍继续坚持工作。
The teacher kept on asking the students questions until the bell rang．老师不断向学生提问，直到铃响。

keep或keep on后跟表示动作的-ing形式，不可接动词不定式或表示静止状态的-ing形式，不能说He kept on to talk. 也不能说They kept on sitting.
7.as well as意为和，同；不但……而且。如果主语是单数，后面有as well as引起的短语，谓语动词仍用单数。如：

Lily as well as Lucy was at home．莉莉和露西都在家里。
as well as还可作“不但……而且”解，相当于not only…but also，但前者强调句子重心在as well as前，后者强调重心在but also后。如：
We students of English should study Chinese as well as English. ( =We students of English should study not only English but also Chinese. ) 我们学英语的学生不但要学英语，还要学汉语。
