         Unit 6 A Great Young Athlete
                  攻克要点
词汇搜索
健康的“成长“
【原句扫描】My neighbor and I grew up together.
【用法透视】grow的过去式及过去分词为grew, grown。它属于不规则变化。
1 及物动词,表示“种“的意思。例如:
Could you tell me if you grow cotton in your country? 你能告诉我你们国家是否种植棉花吗?
2 不及物动词,表示“生长“。例如:
It often rains and the crops grow fast. 经常下雨,庄稼长得很快。
3 半系动词,表示“变得“的意思,后面常加形容词作表语。例如:
As it was growing dark, I came to a car stuck in a drift. 天渐渐黑下来的时候,我走到一辆被堵在雪堆里的小汽车那。
4 常用的结构:grow up的意思是“长大,成长“。注意区别grown-up, 它表示“成年人“的意思,复数直接加“-s“。例如:
When he grew up, he became a great scientist. 他长大后,成了一位伟大的科学家。
The grown-ups in my hometown are studying hard in their spare time. 家乡的成年人在利用业余的时间刻苦学习。
5 辨析 grow, become, get, go, turn 的用法。
这几个词都可以做系动词,表示“变成“的意思。但具体用法有所不同。 Become, get, go通常表示变化的过程已经完成,become 比较证实,get 和go 比较口语化。例如:
Mike becomes ill. 麦克病了。
He has got rich. 他变富了。
He must have gone mad. 他准是疯了。
Grow有“逐渐变成新的状态“的含义。例如:
My younger brother is growing tall. 我弟弟舰舰长高了。
Turn有“成为完全不同的事物“的含义。Turn用作连系动词时,后面也可接名词作表语;名词前面不用a或an。但在become后面做表语的名词前则要用a或an。例如:
The milk turned sour. 牛奶变酸了。
The young worker has turned writer. 那位青年工人已成了一名作家。
The young worker has become a writer. 那位青年工人已成了一名作家。
到底相差多少?
【原句扫描】We played together almost every day.
【用法透视】almost为副词,意思是“几乎,差不多。同义词nearly。例如:
They produce waste gases almost as harmful as the gases from the factories.
它们排出的废气和工厂排出的废气几乎一样有害。
【知识拓展】almost常用来修饰形容词,动词。它可以放在no, none, nothing的前面,但不能用not修饰。例如:
The boy almost wept every time he was scolded. 那孩子每次受到责骂时差不多都要哭。
He said almost nothing worth hearing. 他说几乎没什么值得听的。
【词汇辨析】 almost, nearly
almost和nearly都有“几乎,差不多“的意思,有时可以通用。
例如:
It is almost ( or nearly ) eleven o‘clock. 差不多11点钟了。
Almost和nearly的区别是:almost所表达的相差程度较nearly小,有very nearly的含义。nearly表示“差不多,几乎“的意思,他着眼于不是部分,一般用来修饰表示肯定意义的词语,不能与never, nobody, no one, nothing, nowhere, no 和none连用,这一点正好与almost相反。
例如:
We are nearly there. 我们快到了。
It‘s nearly tow o‘clock. 将近两点钟了。
当句子谈得不是向某个目标发展的趋势,也不是容易衡量的东西时,不用nearly,而要用almost,不应说:I nearly think you are right. 而应说I almost think you are right. 我还不完全相信你是对的。
Nearly现代英语常用作程度副词,等于almost,不能用以表示地点。not nearly的意思是“远不是,远不像“,而almost则不能这样用。例如:
Nearly everyone knows it. 几乎人人都知道了。

句型刷新
......和......一样
【原句扫描】And new friends are almost as good as old friends.
【用法透视】as ... as ... 意为“......和......一样“,第一个as相当于副词,而第二个as则是连词,引导方式状语从句或比较状语从句。如:
They produce waste gases almost as harmful as the gases from factories.
它们排出的废气和工厂排出的废气几乎一样有害。
Come as early as possible. 尽可能早点来。
形容词有三个比较等级,即原级、比较级和最高级。这里主要谈谈含有as的原级用法:
形容词原级(其中也提到了副词的使用)
形容词的原级形式与形容词本身形式相同,形容词的原级形式用来描述人与人、事与事之间的某一方面的相同或不同。其基本结构有:
1 表示双方程度相等,用“as...as“结构,意思是“......和......一样“。
基本句式:
A. 主语 + 谓语 + (系动词)+ as + 原级形容词 + as ...
B. 主语 + 谓语 + (行为动词)+ as + 原级副词 + as ...
例如:
Your jacket is as new as mine. 你的夹克衫和我的一样新。
I work just as hard as he does. 我工作同他一样努力。
2 表示双方程度不相等,用“not so ( as ) ... as...“结构,意思是“......和......不一样“,可译为“......不如......“或“......没有......“。
基本句式:
A. 主语 + 谓语(系动词)+ not so (as) + 原级形容词 + as ...
B. 主语 + do not ( does not) + 谓语(行为动词)+ as ...
例如:
Your jacket is not so ( as ) new as mine. 你的夹克衫不如我的新。
I don‘t work so hard as he does. 我工作不如他那样努力。
3 注意下列句式:
as many + 可数名词 / much + 不可数名词 + as...
例如:
There are as many students in our class as in yours. 我们班的学生人数和你们班的一样多。
He earns as much money as his father does. 他挣的钱和他父亲一样多。
as + 形容词原级 + a (n) + 可数名词单数形式 + as...
例如:
He is as good a person as his father. 他和他父亲一样是个好人。
