Test 2: now let’s check if you listened carefully just now. 3. PresentationUnit 7
Just now we dealt with the details of these two units. Now let’s deal with it generally. Let’s see what are the two units about.
First look at the topic of unit 7: facts about the world. 世界上存在的一些事实
It talks about geography and nature. So who can tell me the title of Unit 7. What’s the highest mountain in the world? So what’s the highest mountain in the world? Yes, Qomolangma. What’s the longest river in the world? The Nile. What is the deepest salt lake in the world? The Caspian Sea. What is the biggest desert in the world? The Sahara.
The grammar of this unit is comparatives and superlatives with adjectives and adverbs. 形容词副词的比较级和最高级。We have reviewed this part before, so let’s pass it.
Which animal is mentioned in 2b? Can you use some sentences to describe it? The sentence should be right, OK?
That’s all we learned in Unit 7, now let’s come into Unit 8.
Unit 8
The topic of unit 8 is literature and music. So the title is ? Have you read Treasure Island?
The grammar in this unit is present perfect tense. We use it to talk about recent events and experiences. OK, give you 1 minute to discuss when we use the present perfect tense, the form and the signs. So, now who can tell me when we use present perfect tense, the form of it and the signs. 用法：表示过去发生或已经完成的动作对现在造成的影响或结果； 过去某一时间开始一直持续到现在的动作或状态，也许还要继续持续下去。 结构：have/has +p.p.
标志词：1. Adv.: already, ever, never, just, yet, still, recently, lately ; 2. 到目前为止：So far, up to now, until now; 3.in the past/last few years; 4. Since 5. for
This tense is a little difficult to you, so look at the ppt and take notes. Then do test 3, 最后一道题，瞬间动词转化为延续性动词才能与表示时间段的时间状语连用。（见试题研究P148）
Let’s come back to the content. What kind of literature we learned in this unit? Novel. And what music we learned in this music. And we learned a passage named “A country music song changed her life forever”. So does music change your life? How does it change?
