【 指点迷津 】
单元重点词汇点拨
1 . pingpong 乒乓球
〖 点拨 〗乒乓球也可说 table tennis .
She plays pingpong very well . 她乒乓球打得很好。
2 . hard-working 努力工作的
He is a hard-working teacher . 他是一位勤奋的老师。
〖 点拨 〗类似的词如：peace-loving爱好和平的。
3 . happily 幸福地，快乐地
The children are playing happily . 孩子们正愉快地玩着。
〖 点拨 〗该词为 happy 的副词形式，作状语。happiness是其名词形式。注意：live a happy life过着幸福的生活。
4 . easily 容易地，轻易地
We did it easily . 我们很容易地把它做了。
〖 点拨 〗其形容词为 easy .
It is easy for sb to do某人干……很容易。It is easy for her to bring the books here .
5 . carefully 仔细地，小心地
Listen to the teacher carefully ! 仔细听老师讲 !
〖 点拨 〗该词为 careful 的副词。careless粗心大意的。carefully = with care认真地。
You’d better do your homework carefully .
6 . worried 担心的，烦恼的
〖 点拨 〗注意 worry 可作动词和名词“担心，焦虑”，be worried about = worry about “对…感到担心”。
－ What’s the matter with you , Tom ?
－ My parents haven’t been back yet . I am worried about it .
单元词组思维运用
1 . telephone number 电话号码
What is your telephone number . 你的电话号码是多少 ?
Perhaps his telephone number is wrong .
－ Is this 9998345 ?
－ Sorry , you have the wrong number .
2 . do some shopping 买些东西
We're going to do some shopping . 我们打算购买一些物品。
〖 提示 〗类似词组还有：do sport 从事运动 / do the cooking 烹调，烹饪 / do washing 洗衣服 / do cleaning 做扫除 / do one's homework 做家庭作业 / do one's lesson 做功课
Mr . Smith likes doing sport after meals . 史密斯先生喜欢饭后参加体育运动。
Is Rose going to do washing this afternoon ?
I don’t like to do shopping with her this afternoon , Mum .
3 . Please help yourself 请随便吃，请自己动手 ( 拿、吃、抽烟等 )
Please help yourself to wine . 请随便用酒。
〖 提示 〗表吃什么，拿什么时，该词组要加介词 to 再加宾语。
Boys , help yourselves to more bananas and oranges .
Sir , help yourself to some cigarettes (香烟).
注意：help sb with帮助某人干…… 。She always helps me with my Chinese on Sunday .
4 . get ready for 为……做好准备，为……准备好
Have you got ready for the party ? 这个聚会你已经准备好了吗 ?
〖 点拨 〗get ready to do准备好干…… 。Please get ready to run , class .
5 . on the other side of 在……的另一边
On the other side of the river there are some banana trees . 在河的对岸，有许多香蕉树。
On the other side of the street there is a book shop .
〖 提示 〗指两者之中的另一边。
6 . like to do 与 like doing：
〖 提示 〗这两者都表示“喜欢做什么”。区别如下：
like to do 指喜欢做特定的或某次具体的行动，指一时的爱好。
I like to swim in the river . 我喜欢在这条河游泳。 ( 特定场合的具体行动 )
( 试比较：I like swimming . 我喜欢游泳。 )
like doing 指喜欢做某事，即长期的爱好和兴趣。试比较：
Do you like swimming ? 你喜欢游泳吗 ? ( 指长期的爱好 )
Would you like to swim with me tomorrow ? 你愿意明天和我一起去游泳吗 ? ( 特指明天一次具体行动 )
另外：如果用于否定结构，like to do 与 like doing 就没有什么区别，可以换用。如：
I don't like smoking = I don't like to smoke . 我不喜抽烟。
7 . like 与 would like 的区别：
〖 提示 〗like ( 喜欢，爱好 ) ，后接名词、代词、不定式或动名词。
Do you like fish ? 你喜欢 ( 吃 ) 鱼吗 ?
would like 意为“想要，愿意”解时，是 wish 和 want 的意思。用于礼貌性地提出要求或表示愿意提供帮助。其后可接名词、代词、动词不定式。但不能接动名词。
Would you like something to eat ? 你想吃点什么东西吗 ?
would like sb to do愿意让某人干 ……。
My father would like me to go to Beijing with hin this summer .
二、学海导航
【 学法指要 】
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。

【 心中有数 】
单元语法发散思维
简单句
在句子中应注意谓语动词和主语在人称和数上必须一致。
1 ) 主语 + 不及物动词 ( 谓语 )
The moon rose . 月亮升起来了。
另外：在这种句型中，主语可被定语修饰。谓语常被副词、介词词组等修饰，用来说明动作的程度、时间、地点、状况等。如：
The sun rises . 太阳升起来了。
The red sun rises . 红太阳升起来了。
The red sun rises in the east . 红太阳在东方升起。
2 ) 主语 + 及物动词 + 宾语
All my friends like to study English and Chinese .
另外：及物动词除必须有宾语外，还可有修饰语，这点与不及物动词相同。修饰动词的状语通常放在句末。这些状语多数是副词或介词短语，也可用名词短语、不定式短语、分词短语等。宾语可以是名词、代词、不定式等。如：
They speak English quite well . 他们英语讲得好。 ( 副词作状语 )
3 ) 主语 + 连系动词 + 表语
My brother is a singer .My mother is a nurse .
另外：在这个句型中，连系动词以 be 动词为最多，此外还有 look , become , keep , get , turn 等。表语可以是名词、代词、形容词、介词短语等。
It's getting colder and colder . 天气越来越冷。
Please keep quiet ! 请保持安静 !

※ 英汉互译
1 . 白天 2 . 时常 3 . 继续 4 . 去散步
5 . 打电话给…… 6 . get warm 7 . at the moment 8 . by the way
9 . feel happy 10 . take - away food
答案：1 . day - time 2 . at times 3 . go on 4 . go for a walk 5 . ring up 6 . 变暖 7 . 此刻 8 . 顺便说一下 9 . 感到高兴 10 . 熟食
※ 要点分析
1 . Now you can ______ the food at home .
A . do B . making C . cook D . doing
答案 C . do , make , cook 都含有“做”的含义，但用在食物上则只用 make 和 cook , make 侧重于面食的制作，如包饺子，做蛋糕等，而 cook 侧重“烹饪”，句中 can 为情态动词，后加动词 cook 原形。
2 . I saw him ______ the car , and he went into that shop .
A . getting on B . getting into C . getting off D . getting out of
答案 D . 上、下小汽车时不用 get on / off 短语，而要用 get into / out of , 另外前后两分句由 and 连接为并列句，前后动作应一致，不可能上了小汽车又进了商店，所以应选择下车，即 getting out of。
3 . There ______ water in the bottle .
A . is no B . is not C . are no D . are not
答案 A . water 为不可数名词，谓语动词要用单数形式，因此可排除C、D项，另外 no = not any , any 用来修饰 water 不可缺，因此不能只用 is not , 而要选A . is no。
4 . I didn't know why she ______ worried .
A . is B . felt C . looks D . feeled
答案 B . 在主从复合句中，除主句为一般现在时的情况外，主从句在时态上一律要保持一致，本题主句为一般过去时，因此从句也要用过去的时态，D项中 feeled 为一种错误的过去式形式，因此选B。
5 . Miss Liu will never be late , ______ ?
A . won't she B . will Miss Liu C . is she D . will she
答案 D . never 为否定副词，意为“从来没有”因此陈述部分为否定句，那么反意疑问句的疑问部分要用肯定形式 will，主语 Miss Liu 相对应的人称代词为 she，因此选D，类似这种情况的词还有 hardly ( 几乎不 ) ，few , little ( 几乎没有 ) ，nobody , no one ( 没有人 ) ，nothing ( 没有什么 ) 等。

3 . snow ( 现在分词 ) 4 . cloud ( 形容词 )
5 . happy ( 副词 ) 6 . country ( 复数 )
