〖 點撥 〗乒乓球也可說 table tennis .

〖 點撥 〗類似的詞如：peace-loving愛好和平的。

二、學海導航
【 學法指要 】
單元句型思路明晰
1 . as + 副詞 + as
Read this passage as quickly as you can . 你盡快讀完這段短文。
這具句型中第一個 as 為副詞，第二個 as 為從屬連詞，引導程度狀語從句。又如：
He ran as fast as he could . 他盡力地快跑。
He works as hard as you . 他與你一樣努力工作。
2 . Not… 否定主語的句型
Not everyone likes sandwiches . 不見得每個人都喜歡三明治。
not 無論放在句首或句子其它地方，與 all , every 等詞連用時，只表示部分否定，又叫做“部分否定句”。如：
Everyone does not like sandwiches . 每個人不見得都喜歡三明治。
Not everyone is a worker . = Everyone is not a worker . 不見得每個人都是工人。
Not everyone agrees with you . 不是人人都同意你的意見。
Not all people agree with you . 不是大家都同意你的看見。
單元難點疑點釋疑
1 . What can I do for you ? 你要點什么 ?
這是對顧客的禮貌用語，還可以說 Can I help you ? 如：
- What can I do for you ? 你要點什么 ?
- I want to buy a new coat . 我想買件新上衣。
- Can I help you ?
- Two cups of coffee . = Two coffees . 請來兩杯咖啡。
2 . She felt worried . 她很焦急。
feel 是連系動詞， worried 是形容詞，在句中作表語。turn , get , look , be 等動詞也是連系動詞，都可接形容詞構(gòu)成系表結(jié)構(gòu)。如：
He felt happy . 他很高興。
The trees turn green . 樹兒綠了。
※ 表示具有某種性質(zhì)、特征或處于某種狀態(tài)。常用的有 be , appear , feel , sound , seem , book , smell , taste 等。例如：
It is not late . 時間還不晚
The dish smells good . 這道菜聞著香。
He seemed to be writing something . 他好象在寫什么東西。
His words sounds all right . 他的話聽起來有道理。
※ 表示動詞所敘述的動作和過程所產(chǎn)生的結(jié)果；或者表示狀態(tài)的變化。常用的有：get , go , come , become , turn , grow , fall , prove , run , make 等。例如：

※ 某種持續(xù)的狀態(tài)。常用的有：keep , continue , stand等。例如：

※ 除 make 等個別詞外，幾乎所有的連系動詞都能接形容詞作表語。例如：
Our country is getting stronger and stronger . 我們國家日益強大。
※ 接名詞作表語的有：become , get , look , make , seem , turn 等。例如：
Now you look a grown-up young man . 現(xiàn)在你看上去已經(jīng)是一個成年的小伙子了。
One tree does not make a wood . 獨木不成林。
He used to be a soldier till he turned writer . 他當作家之前曾是戰(zhàn)士。
※ 我們還應注意某些連系詞和形容詞的固定搭配及其褒貶色彩。比如，come 多接褒義形容詞，而 go 則多接貶之形容詞。例如：
come true / right 變?yōu)楝F(xiàn)實 / 正確
go bad / hungry / mad / blind / deaf / tired / …變壞 / 餓 / 瘋 / 瞎 / 聾 / 累……
grow rich / tall / large / clever / old…變得富裕 / 高 / 大 / 聰明 / 年老……
fall ill / asleep / silent / …生病 / 睡著 / 沉默……
3 . I'm worried about my party . 我正擔心晚會呢 ?
be worried about 意為“為……而擔心”。注意該詞組表示擔憂的狀態(tài)。如：
Mother is worried about his health . 母親擔心他的健康。
Are you worried about the meeting ? 你擔心開會的事嗎 ?
4 . I'll get another one now . 我現(xiàn)在再拿一根來。
one ( s ) , other ( s ) the other ( s ) 及 another 的區(qū)別：
one 有下列幾種意思：1 ) 可指人或表示一種；2 ) 常用來代替前面剛提到的可數(shù)名詞，以
避免重復，如可數(shù)名詞為復數(shù)，就要用 ones 來代替；3 ) 表示“一個…，另一個…”用“one…the other…”。
the others 表示其余的幾個，要用定冠詞 the。
others 表示泛指“別人”或“別的東西”，常不加定冠詞。
another 意為“另一個，又一個”強調(diào)三個或三個以上人 ( 或事物 ) 中的“另一個”。
試比較：
A：Which sweater would you like , the red one or the blue one ? 你想要哪件毛衣，紅色的還是藍色的 ?
B：The red one . 紅色的。
I have two sisters . One is a teacher , the other is a doctor . 我有兩個姐姐，一個是教師，另一個當醫(yī)當。

【 心中有數(shù) 】
單元語法發(fā)散思維
簡單句
在句子中應注意謂語動詞和主語在人稱和數(shù)上必須一致。
1 ) 主語 + 不及物動詞 ( 謂語 )
The moon rose . 月亮升起來了。
另外：在這種句型中，主語可被定語修飾。謂語常被副詞、介詞詞組等修飾，用來說明動作的程度、時間、地點、狀況等。如：
The sun rises . 太陽升起來了。
The red sun rises . 紅太陽升起來了。
The red sun rises in the east . 紅太陽在東方升起。
2 ) 主語 + 及物動詞 + 賓語
All my friends like to study English and Chinese .
另外：及物動詞除必須有賓語外，還可有修飾語，這點與不及物動詞相同。修飾動詞的狀語通常放在句末。這些狀語多數(shù)是副詞或介詞短語，也可用名詞短語、不定式短語、分詞短語等。賓語可以是名詞、代詞、不定式等。如：
They speak English quite well . 他們英語講得好。 ( 副詞作狀語 )
3 ) 主語 + 連系動詞 + 表語
My brother is a singer .My mother is a nurse .
另外：在這個句型中，連系動詞以 be 動詞為最多，此外還有 look , become , keep , get , turn 等。表語可以是名詞、代詞、形容詞、介詞短語等。
It's getting colder and colder . 天氣越來越冷。
Please keep quiet ! 請保持安靜 !

單元能力立體檢測
※ 英漢互譯
1 . 白天 2 . 時常 3 . 繼續(xù) 4 . 去散步
5 . 打電話給…… 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 . 變暖 7 . 此刻 8 . 順便說一下 9 . 感到高興 10 . 熟食
※ 要點分析
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”的含義，但用在食物上則只用 make 和 cook , make 側(cè)重于面食的制作，如包餃子，做蛋糕等，而 cook 側(cè)重“烹飪”，句中 can 為情態(tài)動詞，后加動詞 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、下小汽車時不用 get on / off 短語，而要用 get into / out of , 另外前后兩分句由 and 連接為并列句，前后動作應一致，不可能上了小汽車又進了商店，所以應選擇下車，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 為不可數(shù)名詞，謂語動詞要用單數(shù)形式，因此可排除C、D項，另外 no = not any , any 用來修飾 water 不可缺，因此不能只用 is not , 而要選A . is no。
4 . I didn't know why she ______ worried .
A . is B . felt C . looks D . feeled
答案 B . 在主從復合句中，除主句為一般現(xiàn)在時的情況外，主從句在時態(tài)上一律要保持一致，本題主句為一般過去時，因此從句也要用過去的時態(tài)，D項中 feeled 為一種錯誤的過去式形式，因此選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 為否定副詞，意為“從來沒有”因此陳述部分為否定句，那么反意疑問句的疑問部分要用肯定形式 will，主語 Miss Liu 相對應的人稱代詞為 she，因此選D，類似這種情況的詞還有 hardly ( 幾乎不 ) ，few , little ( 幾乎沒有 ) ，nobody , no one ( 沒有人 ) ，nothing ( 沒有什么 ) 等。
※ 詞形變化
1 . day ( 反義詞 ) 2 . long ( 比較級 )
3 . snow ( 現(xiàn)在分詞 ) 4 . cloud ( 形容詞 )
5 . happy ( 副詞 ) 6 . country ( 復數(shù) )
7 . stop ( 過去式 ) 8 . beautiful ( 最高級 )
9 . stop ( 第三人稱單數(shù) ) 10 . we ( 名詞性物主代詞 )
答案：1 . night 2 . longer 3 . snowing 4 . cloudy 5 . happily 6 . countries 7 . stopped 8 . most beautiful 9 . stops 10 . ours
