Scientists in the UK have found a way to produce blood on a large scale. The blood is good enough to give to patients who need blood in hospital. For a number of years, they have been able to produce red blood cells in a laboratory. However, the process to do that was very slow and they could not produce a lot of blood. So the blood was very expensive. The new way means scientists can make blood with no amount limitation. A researcher said, “We have shown a possible way to keep on producing red cells.”

Another researcher told reporters his team now needs the technology to produce blood on a large scale. He said that to produce that much blood would be quite a challenge. The next step of their work is to look at methods of producing more. He said that his team would produce only rare types of blood at the beginning. He said these are difficult to find with usual blood donation resource. He said, “The first step of producing red blood cells is likely to be for patients with rare blood groups, because suitable red blood cell donations can be difficult to find.” With this technology, blood-losing will no longer be a problem. Many lives will be saved.

1.Where did people produce blood in the past?

A In the factory.

B In the hospital.

C In the laboratory.

D In the blood donation station.

解析：选C。细节理解题。根据第一段第三句For a number of years, they have been able to produce red blood cells in a laboratory. 可知过去人们在实验室生产血液，故选C。

2.Why was blood expensive in the past?

A It was hard to produce red blood cells.

B It was slow to produce and little could be produced.

C The blood donation resource was hard to find.

D The demand was much larger than productive ability.

解析：选B。推理判断题。根据第一段第四、五句However, the process to do that was very slow and they could not produce a lot of blood. So the blood was very expensive.可知过去造血过程很慢且造血量少，因此血液昂贵，故选B。
