5、單元以Cloning為話題，旨在通過單元教學，使學生了解克隆技術(shù)的優(yōu)缺點，學會表達和支持個人觀點，能用所學的有關(guān)Cloning的詞匯去表述自己對這一新技術(shù)的觀點和看法。1) Warming Up提供了四幅有關(guān)Dolly the sheep(多莉羊)，A strawberry plant(草莓植物)，Identical dogs(克隆狗) ，Twins（雙胞胎嬰兒）的圖片，讓學生用已有的知識和經(jīng)驗討論對克隆技術(shù)的看法與觀點。2) Listening是關(guān)于人類克隆的聽力材料，難度中等。3) Speaking根據(jù)材料，四人小組合作，要求把自己對克隆嬰兒的態(tài)度和感覺用相關(guān)的語言表達出來。語言要得體，鍛

6、煉語段表達能力。4) Pre-reading是Reading的熱身活動，它要求采用與同學討論交流的方式談?wù)撚嘘P(guān)克隆的相關(guān)知識。5) Reading是一篇介紹克隆技術(shù)的說明文。6) Comprehending第一題所給出的表格讓學生根據(jù)課文內(nèi)容列舉克隆技術(shù)的優(yōu)缺點；第二題讓學生根據(jù)所擁有的知識來評價作者的觀點；第三題要求學生用自己的語言闡述對克隆技術(shù)的觀點并給出理由。 7) Learning about Language分詞匯和語法兩部分，其中Discovering useful words and expressions 是根據(jù)語境在運用中掌握詞匯。Discovering useful str

51、positive clauses?

52、 the life of the original sheep.T: Now let me explain something about the appositive clauses. The appositive clause is a clause used as an appositive. The clause is an explanation to the noun before. The appositive clause belongs to noun clauses. Most of the appositive clauses may be introduced by t

53、he conjunction that. A content clause is frequently in apposition with such nouns as fact, news, idea, thought, question, reply, report, remark, hope, belief, suggestion etc. 在句中指代同一事物，用以說明或解釋該事物的成分叫做同位語。單詞、短語和從句都可用作同位語；同位語通常位于所說明的先行詞之后，常用來說明身份、職務(wù)及稱號等情況。1. 名詞或名詞性短語作同位語，有時可用逗號與其說明的名詞分開；代詞、數(shù)詞作同位語，一般不用

54、逗號分隔。如：Mr Brown, one of my best friends, enjoys watching TV. 我的一位好朋友布朗先生喜歡看電視。They each have different opinions about it. 他們對那件事各有不同的意見。（each作they的同位語）She bought some apples for us three. 她給我們?nèi)齻€人買了些蘋果。（three作us的同位語）2. 動名詞、動詞不定式、形容詞及介詞短語作同位語，有時用逗號分隔。如：He tried to achieve the impossible, earning a mil

55、lion dollars in a week. 他試圖實現(xiàn)不可能的事，即一周賺一百萬美元。He has a plan to rebuild this city. 他有重建這座城市的計劃。（動詞不定式作同位語）He read all kinds of books, ancient and modern, Chinese and foreign. 他讀了很多書，古今中外都有（adj.作同位語）3. especially, mainly, mostly, for example, namely, that is, that is to say, or, in other words, such as

56、, say, chiefly等單詞或短語后面均可接同位語。如：Only one person can do the job, namely you. 只有一個人能做這項工作，那就是你。He is coming next Friday, that is to say, on the 25th. 他下星期五，也就是二十五號來。4. 同位語從句一般放在它所解釋或說明的名詞的后面，但有時為了避免頭重腳輕或使句子的結(jié)構(gòu)更加緊湊，可將同位語從句放在句末，從而造成同位語從句被謂語動詞或其他成分詞分隔的現(xiàn)象。如：Word came that he left for Shanghai yesterday. 消息

57、傳來說他昨天去上海了。（同位語從句被came分隔）5. advice （建議）, demand, sugges- tion, proposal, order, request等名詞后面的同位語從句，謂語動詞常用“(should +) 動詞原形”構(gòu)成的虛擬語氣。如：He gave orders that the work (should) be done at once. 他下令那項工作要立刻完成。The old pianist wouldnt listen to our repeated request that he (should) play in public again. 我們一再懇求那位老鋼琴家再公開演奏一次，但他卻不答應(yīng)。More examples: Nobody shares my belief that he was mad. My suggestion that he was mad was not accepted.They are familiar with the opinion th
