② I wish I/you/we/it were …
③ It is a pity we…
3. Grammar: Ellipsis
4. Language use: Manipulate listening, speaking, reading and writing practice
Key points: The structure of expressing wishes
Teaching procedures:
Step 1. Revision
(1) Check the homework exercises.
(2) Revise the names of as many oceans and sees of the world as they know. Write the names on the blackboard.
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. 要是我今天能去海边就好了。wish常常表示比较难以实现的愿望，或与事实相反的情景，因此它所接的从句中总是采用过去式虚拟语气。如：I wish I were younger. 要是我年轻些就好了! Judie wishes she could be an astronaut. 朱迪的愿望是做一名宇航员。(将来不一定能实现)
How I wish I hadn't wasted so much time! 要是我没有浪费那么多时间就好了!(已经浪费了) 注意在引导的宾语从句中表示现在和过去时间的时态不同。
② When did you last go to the seaside? 你上次是什么时候去海边的? 在本句中，last是副词，作时间状语，意为“上一次”或“最后一次”。又如： She was quite well when I saw her last. 我上一次见到她时，她身体还不错。 When did you last get a letter from him? 你最后一次收到他的来信是在什么时候?
I am to speak last at the meeting. 我打算在会议上最后一个发言。last作为形容词使用时要注意有两种情况，作为“上一个的” 一般不加定冠词the,作为“最后的”要加定冠词the。
如：last year 去年 last week 上周
last month 上个月 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. 我们游泳，并从岩石上跳入海里。dive意为“跳水”，既是动词，也是名词，如：He dived from the bridge and saved the drowning child. 他跳入水中救起了那个溺水儿童。I'd like you to dive for pearls for me. 我要你替我潜水寻找珍珠。What a graceful dive! 多么优美的跳水(动作)! dive作为名词，在美国英语中意为“下等的饮酒或赌博场所”。
④ ...let's go to the river to bathe. 让我们下河去游泳。bath和bathe属同一个词源，语义相近，但 bath 是名词，bathe一般是动词，作为“洗澡”时也可作名词使用,它们的读音不同。 如：I'll have a hot bath and go to bed then.我要洗个热水澡然后上床睡觉。We had an enjoyable bath before breakfast. 早饭前我们痛快地游了泳。
The doctor told him to bathe his feet in warm water before going to bed every day. 医生叫他每天睡觉前用温水泡脚。
The countryside was bathed in the warm and bright sunshine. 这一片乡野沐浴在温暖明媚的阳光下。 Did you bathe (yourself) in the sea today? 你今天到海里游泳了吗?
⑤ How long can you hold your breath underwater? 你可以在水下呆多久?
1) hold one's breath意为“屏住呼吸”，注意名词breath与动词breathe的区别。名词breath末尾没有“-e”,读作[bre ]，而breathe末尾有“-e”，读作[bri: ] 。
2) underwater既是形容词、副词也是名词，意为“水下的”、“在水下”或“水底”，如：The diver was carrying out an underwater operation. 那个潜水员正在水下作业。The baby can swim underwater. 这婴孩可在水下游泳。He knows the underwater of this area like the back of his hand. 他对这个地区的水下情况了如指掌。
⑥ Take a keep breath and I'll time you. 作深呼吸，我将给你计时。1) take a deep breath意为“作一次深呼吸”，也可以说
“breathe deeply for once”。
2) 在以前所学的课文中，time一般作为名词出现，本课中
它是动词。如：We timed our journey so that we could arrive before dark. 我们对旅程的时间作了安排，以便我们在天黑之前到达。His words were ill timed. 他的话不合时宜。Shall I time you? 我为你计时好吗?
Please time your steps to the music. 请按音乐调整舞步。
⑦ But don't drown. 但不要淹死。drown既是及物动词，也是不及物动词，意为“(使)淹死”、“(使)淹没”。Some passengers fell overboard and were drowned in the sea. 一些乘客从船上落水，在海里淹死了。Please, please save my drowning cat! 请救救我的落水的猫。The noises in the classroom drowned the teacher's voice. 教室里的喧闹声淹没了老师的声音。
Step 4. Practice

④ How much of the earth’s surface is sea? 71%.
Step 4. Language points of the texts
⑴ Seen from space, the earth is blue. 从太空上看，地球是蓝色的。这是一个省略句，完整的句子是：If it is seen from space, the earth is blue. 在带有时间、让步、条件状语从句的句子中，如果前后主语相同，常可省略从句中的主语和be动词，如果不影响意思，甚至连词也可以省略。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.
时间多一些，我们可以做得更好。
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. 在街上行走时，我看到了一只逃跑出来的老虎。
Although I was tired, I explained the situation to her. / Although tired, I explained the situation to her. 尽管疲劳，我还是将情况向她解释了一下。
观察以上句子便可以发现一些省略的规律：从句中的连词 +
主语+助动词be，主语和be可以省略。这一类常见的从句连词有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. 这是因为地球的三分之二是由浩瀚的海洋组成的。
1)two thirds是一个分数，也可以写作two-thirds。英语中分数的表示法是：分子由基数词表示，分母由序数词表示。分子是一，分母用单数，分子大于一，分母用复数。如：one-third三分之一; three fifths 五分之三
分数所修饰的名词词组作主语时，其谓语动词的数与被其修饰的名词一致。如：Two thirds of the land is covered by forest.
三分之一的地面为森林所覆盖。
One fifth of the students in this department are girls.
这个系里五分之一的学生是女生。
2) make up 意为“组成”、“构成”、“编造”或“弥补”，如：

He is expert at making up stories. 他是编故事的行家。
You should make up for your lost time. 你应该将失去的时间补回来。
⑶ The oceans of the world are salty. 世界上的海水都是咸的。
salty是salt的形容词形式。英语中有许多名词可以通过加-y
形式构成形容词，如：

wealth(财富)-wealthy(富有的) wind(风)-windy(刮风的)
snow(雪)-snowy(下雪的) sun(太阳)-sunny(阳光明媚的)
ice(冰)-icy(滑的) fog(雾)-foggy(有雾的)
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在本句中是系动词，相当于remain, keep的系动词用法，如：The shop stays open until midnight. 这家商店到半夜才打烊。试比较：stay vi.停留；待在 stay n.逗留；停留
Stay where you are or I'll shoot you. 呆在原地别动，否则开枪打死你。
The doctor advised me to stay in for a few days. 大夫叫我在家里呆几天。

⑸ The answer is that the seaweeds produce various chemicals that help keep the sea water clean. 答案是海藻产生各种各样的化学物质， 这些物质可以保持海水清洁。
chemical 既是名词，也是形容词，意为“化合物”、“化学产品”、“化学的”。chemical作为名词使用时常用作复数。如：
This is a chemical change, not a physical one. 这是一个化学变化，而不是物理变化。
⑹ The surface water is warm, and in summer can reach up to 25℃ or even 29℃. 表层的水是温暖的，在夏季可高达摄氏25度，甚至摄氏29度。
up to在句中意为“多达；达到”。又如：The river is up to one hundred metres wide. 这条河宽达100米。
up to还有“直到、到……为止”的意思。如：Up to now, everything has been going on well. 到目前为止，一切顺利。
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. 将地中海的水换成大西洋的海水需要 80年，因为地中海只有一个进口，那正是地中海和大西洋的相汇处。
在此句中，where等于at which引导定语从句修饰only one entrance。meet此处意为“相汇；相遇”。又如：This is the place where three rivers meet. 这是三条河流汇集的地方。
⑻ Coral is not a plant but a variety of animal life of different shapes and bright colours. 珊瑚不是植物，而是许多种形状各异、色彩斑斓的动物生命。
① not...but... 不是…而是… He missed the chance not because he did not know it but because he had to. 他失掉这次机会不是因为他不知道而是因为他不得不这样做。
② variety意为“变化性”；多样；变种；变形；若干不同的事物等”。Life is full of variety. 生活充满了变化。

① construction意为“施工；建筑；建设”，是可数或不可数名词。We are discussing the construction of the new road. 我们正在讨论新路的建造问题。
What's that building under construction? 那座正在建造中的建筑物是什么?
construction的词根是动词construct,它与build是近义词。如：

This is a well-constructed detective story. 这是一个编的很好的侦探故事。
constructive adj. 建设性的 Try to be more constructive at next meeting. 下次开会时多讲些建设性的意见。
② 在此句中for example后面的to build a new port是所举的例子，说明建筑工程。
⑽ It is also very low-lying, at around 395 metres below sea level. 它的地势也低，高度约为海平面以下395米。
below sea level 在海平面以下below 和 above 是一对词，概念较为含糊，包含的上下范围较广。而 under 和 over 概念较明确，under指“在正下方”，over指“在正上方”。
The plane is flying above the area. 那架飞机在这个地区上空盘旋。 below/above average 在平均线以下(上)
below/above freezing point 在冰点以下(上)
above sea level 在海平面以上

③ spring在句是意为“泉”，又如： hot spring 温泉

spring 作为名词还可以用作“春天”。它作为动词使用时是不规则动词，表示“弹跳”，如：
He sprang over the river. 他跳过河去。
The door sprang open. 门突然弹开了。
④ flow意为“流”，注意与float(飘浮)不同。试比较：

Look! What's floating on the river? 看!河上漂的是什么?
⑿ There is very little rain here, merely 60 mm in a year on average. 这里雨水很少，平均每年只有60毫米。
① merely 意为“仅仅”，来自于形容词 mere, mere意为
“只不过(not more than)”，如：She is a mere child. 她只是一个孩子。Usually the trip merely takes about one hour and seventeen minutes. 通常情况下这个旅程只花费1小时17分钟。
I merely said it as a joke. 我只是当笑话说说而已。
② on(an/the) average意为“平均说来”。这个词组常用作句子状语。如：On the average, one out of ten smokers may suffer
from cancer. 平均说来，十分之一的吸烟者易患癌症。
average既是名词、形容词，也是动词。它词性虽多，但语义简单，所以掌握起来并不是很难，如：

Answers: whales; small fish; squid
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. 在南极洲周围的海域，水温总是很低，在冰点以下。① 注意七大洲的名称：
Europe 欧洲; Asia亚洲; Africa 非洲; Oceania 大洋洲; South America 南美洲; North America 北美洲; Antarctica 南极洲
② be freezing意为“刺骨的”、“寒冷的”，如：It is freezing cold today. 今天非常冷。
③ below zero 意为“在冰点以下”，也可以用 below freezing point。如果表示“沸点”，则用boiling point, 介词也是用below, above和at。
⑵ There may be 63,000 fish per cubic metre. 每立方米约有63,000尾鱼。cubic意为“立方的”，来自于名词cube(立方)，如：a cube root 立方根; cube 立方体/3次幂
cubic content 容积; cubic equation 三次方程
⑶ These fish provide the main food for whales. 这些鱼为鲸鱼提供了主食。provide与动词supply语义相同，意为“提供”，结构也相似，但provide不可作名词，supply一般用supply sb. sth.,
supply sth. to sb., 而provide一般经常用provide sb. with sth.,
provide sth. for sb., provide for sth.等结构，如：We must provide
for the entertainment of the visitors. 我们得准备款待我们的客人。We should provide for the shortage of energy in the future.
我们应该为未来的能源短缺做好准备。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. 父母必须为他们的孩子提供衣食。
⑷ A whale may eat a ton of them at a time... 一条鲸鱼一次可吃一吨这样的鱼。at a time 意为“一次”、“一下子”，如：
Take two pills at a time. 一次吃两粒药。
He talked for two hours without stopping at a time. 他一口气讲了两小时。
time 可以组成许多习语，在中学英语中已经或将学习到的
大致如下：
after a time 一段时间以后; at one time 曾经，一度
at the time 眼下，暂时; at that time 那时
at times 有时; for the time being 眼下，暂时
from time to time 有时; in time 及时
in time of danger 在危急时刻; off time 不合时宜
on time 准时; once upon a time 从前
pass the time消磨时光; strike the time报时
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. 鱿鱼住在洋底深处的黑暗之中，可以长到15米长。
① 注意词组at a great depth 和 to a length of 15 meters 中不定冠词的用法，比较以前所学的at a distance, at a speed of, at a height of等。
② 注意名词depth和length的构词，试比较：
wide (宽的) -width (宽度); strong (强壮的) -strength (力量)
long (常的) -length (长度); deep (深的) -depth (深度)
high (高的) -height (高度)
⑹ Instead it has teeth and feeds on squid. 相反它有牙齿并以鱿鱼为食。
① instead是副词，意为“代替”。 如果表示“代之以做某事”，则应该用instead of (doing) sth.，试比较：
If you have no cream, use milk instead. 如果没有奶油，就用牛奶代替。
Instead of playing cards or watching TV, he studies hard every evening. 每天晚上，他不是打牌或看电视，而是刻苦学习。
② feed on意为“以……为主食”，用作不及物动词时等于live on。如：feed既是及物动词，也是不及物动词，在本单元中，它是不及物动词，和介词on连用构成相当于及物动词的词组。又如：Most of the Chinese people feed on rice. 大部分中国人以稻米为主食。
She feeds her cat on milk. 她用牛奶喂猫。
The girls were feeding the leaves to silkworms. 女孩子们正在给蚕喂树叶。
⑺ By doing this the animal can hold its breath for a longer time. 通过这样做，动物可以更长时间地屏住呼吸。By doing sth. 是方式状语，意为“通过做某事”。如：The blind men hoped to know the elephant's appearance by touching and feeling. 盲人们希望通过触摸大象来了解大象的模样。We may solve the problem by negotiating. 我们可以通过谈判来解决这个问题。
by还可以用来表示交通工具，如：by spaceship 坐宇宙飞船
