Period 2
Journey to the West
What do you know about cloning Use the words and phrases to help you.
cell
species
to edit genes
identical genes
to develop artificially
to make an exact copy of
to break the technical barrier
to produce animal models
What do you know about cloning Use the words and phrases to help you.
1.Cloning can be used to edit genes.
2.Cloning can create identical genes.
3.Cloning can make an exact copy of an animal.
4.Scientists have broken lots of technical barriers
when studying cloning.
5.We‘ve cloned several species like sheep,cattle and dogs.
6. Scientists want to produce animal models
that are helpful for medical research.
Look at the title and pictures. Make predictions about the text.

Read paragraphs 4-5. Check answers.
P54 5
Potential benefits Moral concerns
will lead to cures for various diseases has refreshed the technical possibility of cloning of other species
prevent aging
save research time
reduce the number of animals being tested on
producing more accurate results
better treatments
clones should be treated as objects or individuals
clones are inferior
some organizations may abuse the technology
Read paragraph 6 and pay attention to the quote.
What does Einstein’s quote mean
So far, it is still unknown what Will happen to Zhong Zhong and Hua Hua as they grow up. Researchers insist that the science of cloning should be further explored and advanced. As Einstein said, “Science is a powerful instrument. How it is used, whether it is a blessing or a curse to mankind, depends on mankind and not on the instrument. A knife is useful, but it can also kill.”
Para.6
Einstein’s quote means that science itself can’t be judged as good or bad, because it can only function when it is used by humans. He also indicates humans need to be careful with the information they learn through science and to remember to use science for good.
