7、de. think about how they differ. student: i think the twins and a strawberry plant are natural clones; the dolly sheep and growing new plants are man-made.after several minutes, teacher ask some questions and let students answer these questions.teacher: 1. dolly the sheep. its the most famous sheep

8、in the world. do you know how dolly is different from other sheep?student: she was cloned while the others were born naturally. it is the copy of another sheep.teacher: 2. what can you see in the picture?student: i can see a strawberry plant producing runners in a natural form of cloning.teacher: 3.

9、who cut the stem off the plant?student: a gardener. and the gardener is going to put it into a pot to produce another plant. he is actually making a copy of the plant.teacher: 4.what do you know about twins?student: there are twins of the same sex and those of different sexes. the twins here are ide

11、閱讀來驗(yàn)證自己的預(yù)測(cè)，使自身處于一種主動(dòng)認(rèn)知的狀態(tài)。before class, ask the students to search for some information about this topic. now show my questions on the screen, and then let them discuss with each other.questions about cloning:1.what is a clone?2. how is a clone produced?3. what benefits can humans gain from cloning?

12、4. what problems may arise when humans are cloned?suggest answers:1. a clone is an animal or plant produced naturally or artificially from the cells of another animal or plant and is exactly the same as it.2. the cloning of plants is simple and relativity easy. it can be done by taking cuttings (man
