     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 cells.
     Claudia Castillo needed a new windpipe (氣管) 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 (組 織支架). 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 rejec tion. 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 trans- plant operations in the future. Scientists also
believe stem cells might be used to treat Parkinson's disease, heart disease, stroke, ar thritis, 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. )
______________________________________________________________________________________
2. Fill in the blank in Paragraph 2 with proper words. ( Please an swer within 8 words. )
______________________________________________________________________________________
3. Which sentence in the text is the closest in meaning to the fol lowing one? However, Ms
      Castillo's body mistook the new windpipe for her own because doctors put her own cells in it.
______________________________________________________________________________________
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.

閱讀理解。
     One day, when we had been riding in the burning sun for five hours, we came to a narrow, shaky bridge
where a railway crossed a stagnant (發(fā)臭的) pond. For 30 feet there was nothing but the widely-spaced
wooden sleepers under our wheels, and nothing to stop us from falling into the steaming bot below if we
overbalanced. Right under the bridge lay the body of a dead cow. I watched Mat as hc approached the bridge
and rode straight over, without even slowing down. I stopped.
     "What's up?" he shouted, from the other side.
     "I'm not riding over that thing. If I fail, I'll be there with that cow!"
     "There's nothing to it. I just did it, didn't I?"
     "You're stronger and taller. My feet can't touch the ground. You do it for me!"
     Mat said strength didn't come into it and rode off,leaving me staring down into the sickly brown soup. He
would be waiting for me around the next corner, but I knew he would oive me at least ar hour before coming
to help. The sun burned my face; sweat ran off my forehead into my eyes and stuck my shirt to my body;
mosquitoes flew into my mouth when I breathed. To stand still in this place was to kill myself; anyway, to sit
around waiting for Mat to help was more than my feminist pride could take. I rode back along the track a f'ew
hundred yards to get a good run-up (助跑) and over I went. Mat was right: all the obstacles were in my mind.

[     ]
A. He wanted to finish the journey as soon as possible.
B. He felt she should overcome her fear by herself.
C. He didn't believe she was really afraid.

[     ]
A. The body of a dead cow.
