Teaching procedures:
Step 1. Revision

Step 2. Presentation and listening
SB Page 19, Part 1. Ask questions about the picture, and get ss to tell you what they think is happening. Teach the new words. Then play the tape for ss to follow and tell them to answer the following questions:
① Where would Bruce like to go today? (To the seaside)
② What do Bruce and Li Qun talk about? (About the sea; the jobs; Li Qun’s cousin)
Step 3. Reading
Get the students to read the dialogue and then go through the grammatical points and structures.
① I wish I could go to the seaside today. 要是我今天能去海邊就好了。wish常常表示比較難以實(shí)現(xiàn)的愿望，或與事實(shí)相反的情景，因此它所接的從句中總是采用過(guò)去式虛擬語(yǔ)氣。如：I wish I were younger. 要是我年輕些就好了! Judie wishes she could be an astronaut. 朱迪的愿望是做一名宇航員。(將來(lái)不一定能實(shí)現(xiàn))
How I wish I hadn't wasted so much time! 要是我沒(méi)有浪費(fèi)那么多時(shí)間就好了!(已經(jīng)浪費(fèi)了) 注意在引導(dǎo)的賓語(yǔ)從句中表示現(xiàn)在和過(guò)去時(shí)間的時(shí)態(tài)不同。
② When did you last go to the seaside? 你上次是什么時(shí)候去海邊的? 在本句中，last是副詞，作時(shí)間狀語(yǔ)，意為“上一次”或“最后一次”。又如： She was quite well when I saw her last. 我上一次見(jiàn)到她時(shí)，她身體還不錯(cuò)。 When did you last get a letter from him? 你最后一次收到他的來(lái)信是在什么時(shí)候?
I am to speak last at the meeting. 我打算在會(huì)議上最后一個(gè)發(fā)言。last作為形容詞使用時(shí)要注意有兩種情況，作為“上一個(gè)的” 一般不加定冠詞the,作為“最后的”要加定冠詞the。
如：last year 去年 last week 上周
last month 上個(gè)月 last summer 去年夏天
last night 昨晚 last time 上一次
③ We swam and dived off the rocks into the sea. 我們游泳，并從巖石上跳入海里。dive意為“跳水”，既是動(dòng)詞，也是名詞，如：He dived from the bridge and saved the drowning child. 他跳入水中救起了那個(gè)溺水兒童。I'd like you to dive for pearls for me. 我要你替我潛水尋找珍珠。What a graceful dive! 多么優(yōu)美的跳水(動(dòng)作)! dive作為名詞，在美國(guó)英語(yǔ)中意為“下等的飲酒或賭博場(chǎng)所”。
④ ...let's go to the river to bathe. 讓我們下河去游泳。bath和bathe屬同一個(gè)詞源，語(yǔ)義相近，但 bath 是名詞，bathe一般是動(dòng)詞，作為“洗澡”時(shí)也可作名詞使用,它們的讀音不同。 如：I'll have a hot bath and go to bed then.我要洗個(gè)熱水澡然后上床睡覺(jué)。We had an enjoyable bath before breakfast. 早飯前我們痛快地游了泳。
The doctor told him to bathe his feet in warm water before going to bed every day. 醫(yī)生叫他每天睡覺(jué)前用溫水泡腳。
The countryside was bathed in the warm and bright sunshine. 這一片鄉(xiāng)野沐浴在溫暖明媚的陽(yáng)光下。 Did you bathe (yourself) in the sea today? 你今天到海里游泳了嗎?
⑤ How long can you hold your breath underwater? 你可以在水下呆多久?
1) hold one's breath意為“屏住呼吸”，注意名詞breath與動(dòng)詞breathe的區(qū)別。名詞breath末尾沒(méi)有“-e”,讀作[bre ]，而breathe末尾有“-e”，讀作[bri: ] 。
2) underwater既是形容詞、副詞也是名詞，意為“水下的”、“在水下”或“水底”，如：The diver was carrying out an underwater operation. 那個(gè)潛水員正在水下作業(yè)。The baby can swim underwater. 這嬰孩可在水下游泳。He knows the underwater of this area like the back of his hand. 他對(duì)這個(gè)地區(qū)的水下情況了如指掌。
⑥ Take a keep breath and I'll time you. 作深呼吸，我將給你計(jì)時(shí)。1) take a deep breath意為“作一次深呼吸”，也可以說(shuō)
“breathe deeply for once”。
2) 在以前所學(xué)的課文中，time一般作為名詞出現(xiàn)，本課中
它是動(dòng)詞。如：We timed our journey so that we could arrive before dark. 我們對(duì)旅程的時(shí)間作了安排，以便我們?cè)谔旌谥暗竭_(dá)。His words were ill timed. 他的話不合時(shí)宜。Shall I time you? 我為你計(jì)時(shí)好嗎?
Please time your steps to the music. 請(qǐng)按音樂(lè)調(diào)整舞步。
⑦ But don't drown. 但不要淹死。drown既是及物動(dòng)詞，也是不及物動(dòng)詞，意為“(使)淹死”、“(使)淹沒(méi)”。Some passengers fell overboard and were drowned in the sea. 一些乘客從船上落水，在海里淹死了。Please, please save my drowning cat! 請(qǐng)救救我的落水的貓。The noises in the classroom drowned the teacher's voice. 教室里的喧鬧聲淹沒(méi)了老師的聲音。

Step 4. Language points of the texts
⑴ Seen from space, the earth is blue. 從太空上看，地球是藍(lán)色的。這是一個(gè)省略句，完整的句子是：If it is seen from space, the earth is blue. 在帶有時(shí)間、讓步、條件狀語(yǔ)從句的句子中，如果前后主語(yǔ)相同，常可省略從句中的主語(yǔ)和be動(dòng)詞，如果不影響意思，甚至連詞也可以省略。如：
If we are given more time, we can do it better.
If given more time, we can do it better.
Given more time, we can do it better.
時(shí)間多一些，我們可以做得更好。
While I was walking in the street, I saw an escaped tiger. / While walking in the street, I saw an escaped tiger. / Walking in the street, I saw an escaped tiger. 在街上行走時(shí)，我看到了一只逃跑出來(lái)的老虎。
Although I was tired, I explained the situation to her. / Although tired, I explained the situation to her. 盡管疲勞，我還是將情況向她解釋了一下。
觀察以上句子便可以發(fā)現(xiàn)一些省略的規(guī)律：從句中的連詞 +
主語(yǔ)+助動(dòng)詞be，主語(yǔ)和be可以省略。這一類常見(jiàn)的從句連詞有once, when, while, if, unless, although, though, even though, even if等等。
⑵ This is because two thirds of the earth is made up of vast oceans. 這是因?yàn)榈厍虻娜种怯珊棋暮Ｑ蠼M成的。
1)two thirds是一個(gè)分?jǐn)?shù)，也可以寫作two-thirds。英語(yǔ)中分?jǐn)?shù)的表示法是：分子由基數(shù)詞表示，分母由序數(shù)詞表示。分子是一，分母用單數(shù)，分子大于一，分母用復(fù)數(shù)。如：one-third三分之一; three fifths 五分之三
分?jǐn)?shù)所修飾的名詞詞組作主語(yǔ)時(shí)，其謂語(yǔ)動(dòng)詞的數(shù)與被其修飾的名詞一致。如：Two thirds of the land is covered by forest.
三分之一的地面為森林所覆蓋。
One fifth of the students in this department are girls.
這個(gè)系里五分之一的學(xué)生是女生。
2) make up 意為“組成”、“構(gòu)成”、“編造”或“彌補(bǔ)”，如：

⑶ The oceans of the world are salty. 世界上的海水都是咸的。
salty是salt的形容詞形式。英語(yǔ)中有許多名詞可以通過(guò)加-y
形式構(gòu)成形容詞，如：
weight(重量)-weighty(重的) health(健康)-healthy(健康的)
wealth(財(cái)富)-wealthy(富有的) wind(風(fēng))-windy(刮風(fēng)的)
snow(雪)-snowy(下雪的) sun(太陽(yáng))-sunny(陽(yáng)光明媚的)
ice(冰)-icy(滑的) fog(霧)-foggy(有霧的)
rain(雨)-rainy(下雨的，多雨的) cloud(云)-cloudy(多云的)
⑷ How does sea water stay clean? 海水是如何保持清澈的呢?
stay在本句中是系動(dòng)詞，相當(dāng)于remain, keep的系動(dòng)詞用法，如：The shop stays open until midnight. 這家商店到半夜才打烊。試比較：stay vi.停留；待在 stay n.逗留；停留
Stay where you are or I'll shoot you. 呆在原地別動(dòng)，否則開槍打死你。

⑸ The answer is that the seaweeds produce various chemicals that help keep the sea water clean. 答案是海藻產(chǎn)生各種各樣的化學(xué)物質(zhì)， 這些物質(zhì)可以保持海水清潔。
chemical 既是名詞，也是形容詞，意為“化合物”、“化學(xué)產(chǎn)品”、“化學(xué)的”。chemical作為名詞使用時(shí)常用作復(fù)數(shù)。如：

⑹ The surface water is warm, and in summer can reach up to 25℃ or even 29℃. 表層的水是溫暖的，在夏季可高達(dá)攝氏25度，甚至攝氏29度。
up to在句中意為“多達(dá)；達(dá)到”。又如：The river is up to one hundred metres wide. 這條河寬達(dá)100米。
up to還有“直到、到……為止”的意思。如：Up to now, everything has been going on well. 到目前為止，一切順利。
⑺ It takes 80 years for Mediterranean water to be changed with Atlantic water, as there is only one entrance where Mediterranean meets the Atlantic. 將地中海的水換成大西洋的海水需要 80年，因?yàn)榈刂泻Ｖ挥幸粋�(gè)進(jìn)口，那正是地中海和大西洋的相匯處。
在此句中，where等于at which引導(dǎo)定語(yǔ)從句修飾only one entrance。meet此處意為“相匯；相遇”。又如：This is the place where three rivers meet. 這是三條河流匯集的地方。
⑻ Coral is not a plant but a variety of animal life of different shapes and bright colours. 珊瑚不是植物，而是許多種形狀各異、色彩斑斕的動(dòng)物生命。

⑼ If construction work is going on, for example to build a new port, or if there is any pollution, this will kill the coral. 如果在海里搞建筑工程，例如建造新港口，或者有污染，珊瑚會(huì)被殺死。
① construction意為“施工；建筑；建設(shè)”，是可數(shù)或不可數(shù)名詞。We are discussing the construction of the new road. 我們正在討論新路的建造問(wèn)題。
What's that building under construction? 那座正在建造中的建筑物是什么?
construction的詞根是動(dòng)詞construct,它與build是近義詞。如：

This is a well-constructed detective story. 這是一個(gè)編的很好的偵探故事。
constructive adj. 建設(shè)性的 Try to be more constructive at next meeting. 下次開會(huì)時(shí)多講些建設(shè)性的意見(jiàn)。

⑽ It is also very low-lying, at around 395 metres below sea level. 它的地勢(shì)也低，高度約為海平面以下395米。
below sea level 在海平面以下below 和 above 是一對(duì)詞，概念較為含糊，包含的上下范圍較廣。而 under 和 over 概念較明確，under指“在正下方”，over指“在正上方”。

I merely said it as a joke. 我只是當(dāng)笑話說(shuō)說(shuō)而已。
② on(an/the) average意為“平均說(shuō)來(lái)”。這個(gè)詞組常用作句子狀語(yǔ)。如：On the average, one out of ten smokers may suffer
from cancer. 平均說(shuō)來(lái)，十分之一的吸煙者易患癌癥。
average既是名詞、形容詞，也是動(dòng)詞。它詞性雖多，但語(yǔ)義簡(jiǎn)單，所以掌握起來(lái)并不是很難，如：
Tom's work is above the average at school. 湯姆的學(xué)習(xí)成績(jī)?cè)趯W(xué)校是中等偏上。

Step 3. Reading ---- discussion
Read the text and discuss the questions at the end of the text. Get the ss to talk about the questions in groups of four and monitor them while they are talking. Go through the questions with the whole if time permits.
Step 5. Language points
Tell the ss to read the text and underline the language points. Talk about the language difficulties with the ss.
⑴ In the oceans around Antarctica the temperature of the water is
freezing, always below zero. 在南極洲周圍的海域，水溫總是很低，在冰點(diǎn)以下。① 注意七大洲的名稱：
Europe 歐洲; Asia亞洲; Africa 非洲; Oceania 大洋洲; South America 南美洲; North America 北美洲; Antarctica 南極洲
② be freezing意為“刺骨的”、“寒冷的”，如：It is freezing cold today. 今天非常冷。
③ below zero 意為“在冰點(diǎn)以下”，也可以用 below freezing point。如果表示“沸點(diǎn)”，則用boiling point, 介詞也是用below, above和at。
⑵ There may be 63,000 fish per cubic metre. 每立方米約有63,000尾魚。cubic意為“立方的”，來(lái)自于名詞cube(立方)，如：a cube root 立方根; cube 立方體/3次冪
cubic content 容積; cubic equation 三次方程
⑶ These fish provide the main food for whales. 這些魚為鯨魚提供了主食。provide與動(dòng)詞supply語(yǔ)義相同，意為“提供”，結(jié)構(gòu)也相似，但provide不可作名詞，supply一般用supply sb. sth.,
supply sth. to sb., 而provide一般經(jīng)常用provide sb. with sth.,
provide sth. for sb., provide for sth.等結(jié)構(gòu)，如：We must provide
for the entertainment of the visitors. 我們得準(zhǔn)備款待我們的客人。We should provide for the shortage of energy in the future.
我們應(yīng)該為未來(lái)的能源短缺做好準(zhǔn)備。I'm already provided/supplied with what is necessary. 我需要的一切都有了。Parents must provide/supply their children with food and clothes. 父母必須為他們的孩子提供衣食。
⑷ A whale may eat a ton of them at a time... 一條鯨魚一次可吃一噸這樣的魚。at a time 意為“一次”、“一下子”，如：
Take two pills at a time. 一次吃兩粒藥。
He talked for two hours without stopping at a time. 他一口氣講了兩小時(shí)。
time 可以組成許多習(xí)語(yǔ)，在中學(xué)英語(yǔ)中已經(jīng)或?qū)W(xué)習(xí)到的
大致如下：
after a time 一段時(shí)間以后; at one time 曾經(jīng)，一度
at the time 眼下，暫時(shí); at that time 那時(shí)
at times 有時(shí); for the time being 眼下，暫時(shí)
from time to time 有時(shí); in time 及時(shí)
in time of danger 在危急時(shí)刻; off time 不合時(shí)宜
on time 準(zhǔn)時(shí); once upon a time 從前
pass the time消磨時(shí)光; strike the time報(bào)時(shí)
⑸ The squid live in the dark at a great depth at the bottom of the ocean. It can grow to a length of 15 metres. 魷魚住在洋底深處的黑暗之中，可以長(zhǎng)到15米長(zhǎng)。
① 注意詞組at a great depth 和 to a length of 15 meters 中不定冠詞的用法，比較以前所學(xué)的at a distance, at a speed of, at a height of等。
② 注意名詞depth和length的構(gòu)詞，試比較：
wide (寬的) -width (寬度); strong (強(qiáng)壯的) -strength (力量)
long (常的) -length (長(zhǎng)度); deep (深的) -depth (深度)
high (高的) -height (高度)
⑹ Instead it has teeth and feeds on squid. 相反它有牙齒并以魷魚為食。
① instead是副詞，意為“代替”。 如果表示“代之以做某事”，則應(yīng)該用instead of (doing) sth.，試比較：
If you have no cream, use milk instead. 如果沒(méi)有奶油，就用牛奶代替。
Instead of playing cards or watching TV, he studies hard every evening. 每天晚上，他不是打牌或看電視，而是刻苦學(xué)習(xí)。
② feed on意為“以……為主食”，用作不及物動(dòng)詞時(shí)等于live on。如：feed既是及物動(dòng)詞，也是不及物動(dòng)詞，在本單元中，它是不及物動(dòng)詞，和介詞on連用構(gòu)成相當(dāng)于及物動(dòng)詞的詞組。又如：Most of the Chinese people feed on rice. 大部分中國(guó)人以稻米為主食。
She feeds her cat on milk. 她用牛奶喂貓。
The girls were feeding the leaves to silkworms. 女孩子們正在給蠶喂樹葉。
⑺ By doing this the animal can hold its breath for a longer time. 通過(guò)這樣做，動(dòng)物可以更長(zhǎng)時(shí)間地屏住呼吸。By doing sth. 是方式狀語(yǔ)，意為“通過(guò)做某事”。如：The blind men hoped to know the elephant's appearance by touching and feeling. 盲人們希望通過(guò)觸摸大象來(lái)了解大象的模樣。We may solve the problem by negotiating. 我們可以通過(guò)談判來(lái)解決這個(gè)問(wèn)題。
by還可以用來(lái)表示交通工具，如：by spaceship 坐宇宙飛船
