book 8 unit 2 cloning
warming up and pre-reading

ⅰ. 背景阅读
cloning is the technique of producing a genetically identical duplicate of an organism. a clone is said to be all descendants derived asexually from a single individual, as by cuttings, bulbs, by fission, by mitosis, or by parthenogenesis reproduction. it sounds very different and complicated to us.
in fact, in our daily life, this happens often. for example, gardeners take cuttings from growing plants to make new ones. you often see that your mother picks a small branch from a growing plant to make a new one. if she likes this kind of flowers, she can do cloning. cloning also happens in animals or human beings when twins identical in sex and appearance are produced from the same original egg. the fact is that cloning plants is straightforward but the cloning of animals is more complicated.
 the possibility of human cloning, raised when scottish scientists at roslin institute created the much-celebrated sheep "dolly", aroused worldwide interest and concern because of its scientific and ethical implications. she was the first mammal to be cloned from adult dna taken from an adult cell. previously, animals had only been cloned using embryo cells which already have the potential to become a complete embryo in its own right. the big breakthrough with dolly was to make a clone from an ordinary, adult cell − in this case from a female goat’s udder.

1) the definition of cloning
cloning is a ________ of producing a genetically identical duplicate of an animal or a plant. it happens both in ______ and in_______. they can be cloned by _______ or humans. the former is_______clone while the latter is man-made clone.
2) how does dolly differ from other sheep?
she was ______ by humans while the others were born naturally.

2. discuss the following questions.
1). can you see any cloning happen in our daily life?
2). what benefits can humans gain from cloning?

聚焦名词性从句
[讲一讲] 同学们在学习和使用名词性从句时要特别注意以下几点：
1. 注意连接词that与what的区别：
      that在引导名词性从句时，只起连接作用，不在从句中作任何成分；what在引导名词性从句时不仅起连接作用，而且在从句中充当主语、宾语、表语等。如：
see the flags on top of the building? that was what we did this morning. （what作did的逻辑宾语）
what makes this shop different is that it offers more personal services. （what引导主语从句，且在主语从句中作主语）
2. 注意连接词whether与if的区别：
      whether可引导所有的名词性从句，if一般只能引导宾语从句。在引导宾语从句时两者常可互换，但介词后的宾语从句只能用whether引导；此外，whether后可直接用or not, if则不行。如：
the question is whether he will accept our invitation and come to our party. （whether引导表语从句，一般不用if代替）
can you tell me whether or not the train has left? （与or not直接连用，只能用whether）
3. 注意名词性从句与定语从句的区别：
      名词性从句相当于一个名词，在句中可以充当主语、宾语、表语等，而定语从句相当于一个形容词，在句中充当定语。
      有些连接词如that, which, where, when等，既可引导名词性从句又可引导定语从句；还有些连接词如what, whatever等，不能引导定语从句。如：
he promised to do everything that he could do to help us out. (that引导定语从句)
he promised to do whatever he could do to help us out. (whatever引导宾语从句)
the coat is still where you have left it. (where引导表语从句)
the coat is still in the room where you have left it. (where引导定语从句)

on cloning
the passage introduces  what is  cloning and the procedure of cloning dolly the sheep. however, the birth and death of dolly has evoked much controversy on cloning animals.
as soon as cloning was discovered, there’re more and more disputes about it. to a certain degree, it is bound to benefit human beings a lot as a large medical breakthrough. besides, we can clone the endangered animals and plants to save them, and it can make crops grow better and cows make better milk. as you can see, ‘cloning’ brings us many good changes. however, it has some disadvantages, too. for sone thing, it is against the rule of nature, and may even raise moral risk. for another, although we can clone a person, we can not clone a soul.
 since it is such a controvercial technique, we should be extremely cautious of what we do and thus remember we will surely be respondible for all the results created by ourselves. what is more, the government should make a law to tell how to use this technology. last but not the least, the scientists should study more to let us know more about cloning. if so, i’m sure cloning will change the world with its advantages.

grammar
聚焦名词性从句
[讲一讲] 同学们在学习和使用名词性从句时要特别注意以下几点：
1. 注意连接词that与what的区别：
      that在引导名词性从句时，只起连接作用，不在从句中作任何成分；what在引导名词性从句时不仅起连接作用，而且在从句中充当主语、宾语、表语等。如：
see the flags on top of the building? that was what we did this morning. （what作did的逻辑宾语）
what makes this shop different is that it offers more personal services. （what引导主语从句，且在主语从句中作主语）
2. 注意连接词whether与if的区别：
      whether可引导所有的名词性从句，if一般只能引导宾语从句。在引导宾语从句时两者常可互换，但介词后的宾语从句只能用whether引导；此外，whether后可直接用or not, if则不行。如：
the question is whether he will accept our invitation and come to our party. （whether引导表语从句，一般不用if代替）
can you tell me whether or not the train has left? （与or not直接连用，只能用whether）
3. 注意名词性从句与定语从句的区别：
      名词性从句相当于一个名词，在句中可以充当主语、宾语、表语等，而定语从句相当于一个形容词，在句中充当定语。
      有些连接词如that, which, where, when等，既可引导名词性从句又可引导定语从句；还有些连接词如what, whatever等，不能引导定语从句。如：
he promised to do everything that he could do to help us out. (that引导定语从句)
he promised to do whatever he could do to help us out. (whatever引导宾语从句)
the coat is still where you have left it. (where引导表语从句)
the coat is still in the room where you have left it. (where引导定语从句)
