单元句型思路明晰
1 . as + 副词 + as
Read this passage as quickly as you can . 你尽快读完这段短文。
这具句型中第一个 as 为副词，第二个 as 为从属连词，引导程度状语从句。又如：
He ran as fast as he could . 他尽力地快跑。
He works as hard as you . 他与你一样努力工作。
2 . Not… 否定主语的句型
Not everyone likes sandwiches . 不见得每个人都喜欢三明治。
not 无论放在句首或句子其它地方，与 all , every 等词连用时，只表示部分否定，又叫做“部分否定句”。如：
Everyone does not like sandwiches . 每个人不见得都喜欢三明治。
Not everyone is a worker . = Everyone is not a worker . 不见得每个人都是工人。
Not everyone agrees with you . 不是人人都同意你的意见。
Not all people agree with you . 不是大家都同意你的看见。
单元难点疑点释疑
1 . What can I do for you ? 你要点什么 ?
这是对顾客的礼貌用语，还可以说 Can I help you ? 如：
— What can I do for you ? 你要点什么 ?
— I want to buy a new coat . 我想买件新上衣。
— Can I help you ?
— Two cups of coffee . = Two coffees . 请来两杯咖啡。
2 . She felt worried . 她很焦急。
feel 是连系动词， worried 是形容词，在句中作表语。turn , get , look , be 等动词也是连系动词，都可接形容词构成系表结构。如：
He felt happy . 他很高兴。
The trees turn green . 树儿绿了。
※ 表示具有某种性质、特征或处于某种状态。常用的有 be , appear , feel , sound , seem , book , smell , taste 等。例如：
It is not late . 时间还不晚
The dish smells good . 这道菜闻着香。
He seemed to be writing something . 他好象在写什么东西。
His words sounds all right . 他的话听起来有道理。
※ 表示动词所叙述的动作和过程所产生的结果；或者表示状态的变化。常用的有：get , go , come , become , turn , grow , fall , prove , run , make 等。例如：
The custom has now become a rule . 那习俗已变为成规。
The milk in the cup will go bad . 杯子里的牛奶要坏了。
Her face turned red .
※ 某种持续的状态。常用的有：keep , continue , stand等。例如：
She knew she must keep calm . 她知道她必须保持镇静。
※ 除 make 等个别词外，几乎所有的连系动词都能接形容词作表语。例如：
Our country is getting stronger and stronger . 我们国家日益强大。
※ 接名词作表语的有：become , get , look , make , seem , turn 等。例如：
Now you look a grown-up young man . 现在你看上去已经是一个成年的小伙子了。
One tree does not make a wood . 独木不成林。
He used to be a soldier till he turned writer . 他当作家之前曾是战士。
※ 我们还应注意某些连系词和形容词的固定搭配及其褒贬色彩。比如，come 多接褒义形容词，而 go 则多接贬之形容词。例如：
come true / right 变为现实 / 正确
go bad / hungry / mad / blind / deaf / tired / …变坏 / 饿 / 疯 / 瞎 / 聋 / 累……

grow rich / tall / large / clever / old…变得富裕 / 高 / 大 / 聪明 / 年老……
fall ill / asleep / silent / …生病 / 睡着 / 沉默……
3 . I\'m worried about my party . 我正担心晚会呢 ?
be worried about 意为“为……而担心”。注意该词组表示担忧的状态。如：
Mother is worried about his health . 母亲担心他的健康。
Are you worried about the meeting ? 你担心开会的事吗 ?
4 . I\'ll get another one now . 我现在再拿一根来。
one ( s ) , other ( s ) the other ( s ) 及 another 的区别：
one 有下列几种意思：1 ) 可指人或表示一种；2 ) 常用来代替前面刚提到的可数名词，以
避免重复，如可数名词为复数，就要用 ones 来代替；3 ) 表示“一个…，另一个…”用“one…the other…”。
the others 表示其余的几个，要用定冠词 the。
others 表示泛指“别人”或“别的东西”，常不加定冠词。
another 意为“另一个，又一个”强调三个或三个以上人 ( 或事物 ) 中的“另一个”。
试比较：
A：Which sweater would you like , the red one or the blue one ? 你想要哪件毛衣，红色的还是蓝色的 ?
B：The red one . 红色的。
I have two sisters . One is a teacher , the other is a doctor . 我有两个姐姐，一个是教师，另一个当医当。
The children are cleaning the classroom . Some are sweeping the floor , others are cleaning the window . 孩子们在打扫教室，一些正在扫地，另一些在擦窗子。
Lei Feng was always ready to help others . 雷锋总是乐于助人。
Here are three pencils . One is red , another is blue , the third is yellow .
这里有三支锅笔，一支是红色的，另一支是蓝色的，还有一支是黄色的。
