阅读下面短文, 请根据短文后的要求进行答题。(请注意问题后的字数要求)
Surgeons in Spain have successfully carried out the world’s first organ transplant(移植) using new stem cell technology.Some people are calling it the greatest medical breakthrough so far this century.
But what are stem cells? As we know, most cells in our bodies are designed —for example, a liver cell develops to work in the liver and cannot become a heart cell.But stem cells are different.They are very young and in the laboratory scientists can grow them into different types of cell.
Claudia Castillo needed a new windpipe (气管) after getting a serious disease.Scientists from the University of Bristol took a donor windpipe, from someone who had recently died.They used strong chemicals to remove the donor’s cells, leaving a tissue scaffold (组织支架).This was refilled with cells from Ms Castillo’s windpipe and stem cells from her bone.After four days the cells had grown sufficiently for the windpipe to be transplanted into Ms Castillo.
Currently, transplant patients have to take drugs for the rest of their lives to prevent their bodies rejecting the new organs.These drugs can have bad side-effects, and do not always prevent rejection.But by using Ms Castillo’s own cells, doctors were able to trick her body into thinking the new windpipe was her own organ.Five months on, Claudia Castillo is in perfect health.
This ground-breaking procedure could be used in other transplant operations in the future.Scientists also believe stem cells might be used to treat Parkinson's disease, heart disease, stroke, arthritis, burns and so on..
However, stem cell research is extremely controversial.The most effective stem cells do not come from adults but from embryos (胚胎) created in laboratories which are just a few days old.Many people have religious or ethical objections to growing embryos, even if they can be used to cure diseases.
1.What’s the best title for the passage? (Please answer within 8 words)

_______________________________________________________________________________
4.What do you think of the stem cell transplant? Why? (Please answer within 30 words)
5.Translate the underlined sentence in Paragraph 4 into Chinese.
【回答】
1.Transplant Success/Successful Transplant Using Stem Cells
2.for specific purposes/to serve specific purposes/for certain organs
3.But by using Ms Castillo’ own cells, doctors were able to trick her body into thinking the new windpipe was her own organ.
4.I think it is beneficial to the world because it can cure a lot of diseases./I think it is against the
ethical rules because the stem cells come from embryos which are created in labs.
5.目前,做移植手术的病人靠吃*来维持生命,防止身体排斥新器官。
