高中英语(人教版选修8)教师用书：Unit 2 Section_Ⅰ Warming Up - Reading — Pre-reading(含答案)
Section_ⅠWarming Up & Reading —Prereading 1．What are the advantages and disadvantages of cloning?2．Not only animals but also plants can be cloned. Do you know the difference between them?Please read the following passage to get the answer.A new study of plants that are reproduced by cloning has shown why cloned plants are not identical.Scientists have known for some time that cloned organisms are not always identical: their observable characteristics and traits can vary, and this variation can be passed on to the next generation. This is despite the fact that they are derived (获得) from genetically identical founder cells.Now, a team from Oxford University, the UK, and King Abdullah University of Science and Technology, Saudi Arabia, believe they have found out why this is the case in plants: the genomes (染色体) of regenerate plants carry relatively high frequencies of new DNA sequence mutations (变异) that were not present in the genome of the donor plant.The team reported their findings in this week’s Current Biology.“Where these new mutations actually come from is still a mystery，” said Professor Harberd. “They may arise during the regeneration process itself or during the cell divisions in the donor plant that gave rise to the root cells from which the regenerate plants are created. We are planning further research to find out which of these two processes is responsible for these mutations. What we can sayis that nature has safely been employing what you might call a ’cloning’process in plants for millions of years, and that there must be good evolutionary reasons why these mutations are introduced.”The new results suggest that variation in clones of plants may have different underlying causes from those of variation in clones of animals — where it is believed that the effect of environmental factors on how animal genes are expressed is more important and no similar high frequencies of mutations have been observed.Professor Harberd said, “While our results highlight that cloned plants and animals are very different, they may give us insights into how bacterial and cancer cells replicate themselves, and how mutations arise during these processes which, ultimately, have an impact on human health.”Warming Up1．How much do are natural clone and manmade clone?Clone_is_a_way_of_making_an_exact_copy_of_another_animal_or_plant.Natural_clone_is_one_that_occurs_from_the_“parent”_in_a_natural_form_of_ cloning_without_human_help.Manmade_clone_is_one_produced_through_human_intervention_(介入)．2．Look at these pictures and tell which ones are natural clones and which ones are manmade clones.Natural_clones：AF；Manmade_clones：BCDE3．See another kind of clone.

Unit 2克隆：它将把我们引向何方？Cloning has always been with us and is here to stay. It is a way of making an exact copy of another animal or plant. It happens in plants when gardeners take cuttings from growing plants to make new ones. It also happens in animals when twins identical in sex and appearance are produced from the same original egg. The fact is that these are both examples of natural clones.克隆一直与我们同在，而如今它还要持续下去。
这是一种用来生产与原型完全相同的动植物的方法。
当园艺师从生长着的植物上剪下枝条来培植新植物时，就会产生这种现象。
这种现象也发生在动物身上，从同一个原生卵子产生性别和相貌相同的双胞胎也是克隆。
实际上，这些都是自然克隆现象。
Cloning has two major uses. Firstly, gardeners use it all the time to produce commercial quantities of plants. Secondly, it is valuable for research on new plant species and for medical research on animals. Cloning plants is straightforward while cloning animals is very complicated. It is a difficult task to undertake. Many attempts to clone mammals failed. But at last the determination and patience of the scientists paid off in 1996 with a breakthrough - the cloning of Dolly the sheep. The procedure works like this:克隆技术有两大用途。

姓名，年级：时间：THE RETURN OF THE DINOSAURS?The possibility of cloning fierce and extinct wild animals has always excited film makers。
And they are not the only ones！The popularity（受人喜爱）of films such as Jurassic Park，in which a scientist clones several kinds of extinct dinosaurs，proves how the idea struck a mixture of fear and excitement into people’s hearts①。
But in fact we are a long way from being able to clone extinct animals.Scientists are still experimenting with cloning mammals.This is because the cloning of mammals is still a new science and its story only began seriously in the 1950s as this list shows②：1950s cloning of frogs1970s research using the embryos of mice③1979 work on embryos of sheep and mice1981 first experimental clones of mice1983 first experimental clones of cows1996 first clone of a mammal:Dolly the sheep2000 cow gave birth to a bison（北美或欧洲野牛）2001 China’s first cloned twin calves（小牛）2002 first cloned cats2005 first cloned dog．．．恐龙的回归？克隆凶猛和灭绝的野生动物的可能性一直使电影制片商感到兴奋。

Section_ⅣGrammar_&_Writing复习同位语一、同位语同位语是句子成分的一种，主要用于对名词进行解释与说明。
可充当同位语的有名词(词组)、代词、数词、形容词(短语)、动名词(短语)、不定式(短语)及从句等。
1．名词、代词或数词充当同位语I live with my uncle Tom.我和汤姆叔叔住在一起。
We each put forward a proposal.我们每人提出了一个建议。
She is the oldest among them six.她是他们6人中年纪最大的。
2．名词词组、形容词(词组)、动名词(短语)、不定式(短语)等充当同位语Zhu Zhiwen, a diligent farmer and brilliant singer, is really a hit throughout China.朱之文，一位勤劳的农民、才华横溢的歌唱家，轰动了全中国。
Is this your purpose, to avoid being punished?逃避惩罚，这就是你的目的？二、同位语从句在复合句中用作同位语的从句称为同位语从句。
同位语从句是名词性从句的一种。
它一般放在fact，news，idea，truth，hope，problem，information，belief，thought，doubt，promise，question等抽象名词的后面，对前面的名词作进一步的解释，说明前面名词的具体含义。
1．同位语从句的连接词主要有that, whether, why, who, where, how, when等。
其中that, whether不作成分，that无实际意义，whether意为“是否”；其他连接词具有实义，同时在同位语从句中作一定成分。
引导同位语从句的连接词一般都不能省略。
The news that he was punished soon spread on the Internet.他被惩罚的消息很快在因特网上传开了。
The problem whether we should continue to do the experiment has been solved.我们是否继续做这个实验的问题已经被解决。
I have no idea where he lives.我不知道他住在哪里。

A saying goes that practice makes perfect.熟能生巧是谚语。
(2)名词suggestion, order, demand, command, request等后的同位语从句要使用虚拟语气，即从句谓语用“(should＋)do”。
Our teacher gave us some advice how we (should) use the computer.老师给了我们一些如何使用电脑的建议。
(3)名词doubt (怀疑)后的同位语从句用whether引导；no doubt (毫无疑问)后的同位语从句用that引导。
We have some doubt whether they can complete the task on time.我们怀疑他们能否按时完成任务。
There is no doubt that Zhang Wei will keep his promise.张卫会守信的，这是毫无疑问的。
3．同位语从句和定语从句的区别which代替whether/how不作成分，起连接作用“是否”；“如何”不引导定语从句wh类连接词作成分，起连接作用，有自己的含义，但与先行词之间无关作成分，起连接作用，没有自己的含义，但是代替先行词在从句中作成分吉姆得知整个村子都处在极度危险中的消息。
(that引导同位语从句，解释说明the news 的内容)Do you know the news (that/which) Jim told me?你知道吉姆告诉我的那个消息吗？(that/which引导定语从句，且在从句中作宾语)Ⅰ.用适当的连接词填空1．I have no idea when he will come back.2．The question whether we need more time to do the work or not has not been discussed.3．We express the hope that they will come to visit China again.4．The news that they won the match is true.5．The news that/which you told us yesterday is true.6．Information has been put forward that more middle school graduates will be admitted into universities.Ⅱ.将下列每组句子合并成一个带同位语从句的复合句1．Will the sports meeting be held on time? The question will be discussed tomorrow.The_question_whether_the_sports_meeting_will_be_held_on_time_will_be_discuss ed_tomorrow.2．The headmaster will join us in hiking this Sunday.

Dear Editor，①I’m a senior high school student, named Li Hua.②Now many students have iPads and think it’s a fashion to use them.③Using an iPad, we can listen to music, download a lot of learning materials and read them on the screen.④Apparently, it is helpful to our study, especially to our English listening.⑤Some students, however, bring their iPads to classroom and listen to music with earphones, which makes the teacher and other students greatly annoyed.⑥Some of them even waste precious time in class playing video games.⑦In my opinion, as a student, we should make good use of iPad to help achieve academic success.⑧Our classroom is a place for students to study, and therefore concentration is awfully needed for us to learn our lessons.⑨Furthermore, the school should make it a rule to guide the students to use iPads in a proper way.Yours，Li Hua第一段：说明了使用iPad的好处；第二段：说明了使用iPad的弊端；第三段：提出自己的建议。
