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。
