高二英语Module8 unit2 Cloning高考解读【高考导航】2010高考命题趋向分析：1.differ为高中高频动词。

考查角度如下：1）differ与不同介词（in,from,with）搭配时的辨析；2）differ的形容词形式different的固定搭配be different from的用法；3）名词形式与动词make的搭配。

2010年高考要注意它与make的搭配后河sense等词的短语辨析2.forbid也是新课标的重要词汇。

本单元的in favour of就是其中一个；一般在语境中考查它；2010年仍会对其考查。

4．pay构成的短语中,要注意pay off”得到回报”之意，以及pay for的“为—而付出代价”之意不容忽视。

在语法结构上，pay off表示此意时五被动语态，事作主语5. “主语+谓语+宾语+形容词”句型是英语中的常用句型；对该矩形的考查，多考查形式宾语it，代替后面的不定式或从句真正宾语；2006年湖南卷曾考查过【真题品析】1．________ fire, all exits must be kept clear. [2007 天津卷]A. In place ofB. Instead ofC. In case ofD. In spite of【答案】C 考查介词短语辨析【点拨】按照句意：万一着火的话-------；C项符合。

人教版高中英语选修8Unit2《Cloning》word教案【美文阅读】Pandas can be saved by cloning?从1998年中国科学院动物研究所首席科学家、动物克隆与受精生物学学科带头人陈大元首次正式提出克隆大熊猫到现在，整整16年过去了，陈老仍旧执著于此。

然而爱护大熊猫，怎么说要不要通过克隆的方式呢？China has been exploring every possible means of saving giant pandas，one of the world's most endangered species，from becoming extinct，even if it means resorting to(诉诸) cloning them.Chen Dayuan，a senior scientist who specializes in cloning at the Institute of Zoology in the Chinese Academy of Sciences，introduced the idea of performing cloning techniques on giant pandas in 1998.Using initial funding of 100,000 yuan，Chen successfully produced blastocysts(胚泡) by transplanting the somatic nucleus from sample pandas into the egg cells of rabbits.The move was considered as one of the 10 biggest achievements of science and technology in 1999.It won an award of 6 million yuan and further funding of 5 million yuan for the project from the Ministry of Science and Technology.At first，two embryos were created from a surrogate mother(代母) cat who became pregnant after being in­jected with a blastocyst，but the experiment was abandoned after the cat died.Chen and his team then experimented with surrogacy on black bears.After three years of effort，a black bear became pregnant and the shape of a fetus(胎儿) could be seen on an ultrasound scan(超声波扫描检查)．However，the research was stopped in 2005 because the fetus did not completely develop before the project's deadline.“Those who are against cloning have made their voice s heard throughout the research project on cloning giant pandas.Some people believe cloning goes against nature，but it is actually a pioneering technology.If successful，it is a way tosave endangered animals，”Chen said.Some scientists take a different vie w.“While I agree that research on cloning is meaningful，it is inappropriate to use giant pandas in this type of experiment.The number of pandas is limited and human beings have yet to master knowledge about pandas' pregnancy.Cloning would do little to save the species，”said Wang Dajun，a researcher at the School of Life Sciences，Peking University.In response，Chen said that he would continue his research.【诱思导学】1．Do you think pandas can be saved by cloning？Why?______________________________________________【答案】省略2．Why are some scientists against cloning pandas?______________________________________________【答案】Because they think cloning go against nature.Period ⅠPreviewing(教师用书独具)●教学目标本课时要紧是通过学生对学案所给出的内容的学习，了解本课文中所显现的词汇，初步了解课文以及相关的背景知识，为下一堂课对课文的全面明白得起到一个铺垫作用。
