Cloning
Why plant “clones” aren’t identical 克隆后的植物与母体完全相同吗？植物克隆与动物克隆有 区别吗？这种研究有什么意义呢？
Science Daily (Aug 4,2011)—A new study of plants that are reproduced by cloning has shown why cloned plants are not identical.
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 say is 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.”

②We are glad at the news that he told us. 听到他告诉我们的这个消息我们很高兴。（that从句是限制the news的内容的， 即我们高兴只是因为他告诉的这个news而不是其他的news，故that从句为定语从 句） 2.引导词不同 what,how,whether,whatever 等可引导同位语从句，但不引导定语从句。
他想到可能敌人已逃离这座城市。
三、同位语从句与定语从句的区别 1.作用的不同 同位语从句是用于说明所修饰名词的具体内容的，它与被修饰词语通常可以划 等号；而定语从句是限制所修饰名词的，它的作用是将所修饰的名词与其他类似的
东西区别开来。如：
①We are glad at the news that he will come. 听到他要来这个消息我们很高兴。（news的内容就是that he will come，故that 引导的是同位语从句）
opinion,suggestion,truth等抽象名词，而定语从句所修饰的名词则非常广泛。 另
外，when和where 引导定语从句时，通常只修饰表示时间和地点的名词，而它们引 导同位语从句时却不一定；又如why引导定语从句，它通常只修饰名词the reason，
而它引导同位语从句时则不一定。如：
明天放假的消息不实。
④I've come to the conclusion that it was unwise to do that. 我得出结论这样做是不明智的。 ⑤The fact that the money has gone does not mean it was stolen. 那笔钱不见了这一事实并不意味着是被偷了。
3.引导词的功能不同

Nowadays, cloning has given rise to widespread concern and people’s opinions differ from each other widely on it. Some people are in favour of its development, for they believe it will help people not being able to have their children realize their dream of being parents. Besides, treatment for many incurable diseases can be found, helping those who are in good condition recover from illnesses. Therefore, it will be bound to benefit the development of modern medicine. On the contrary, others object to the idea, thinking that it could raise a storm of moral questions. For example, they could feel cast down to find that some evil leaders may want to clone themselves with the aid of the technology of cloning.
