Bone Marrow Transplantation

Bone marrow is the spongy tissue inside some of your bones,such as your hip and thigh bones. It contains immature cells,called stem cells.The stem cells can develop into the red blood cells that carry oxygen through your body,the white blood cells that fight infections,and the platelets that help with blood clotting.
If there is a problem with your bone marrow,a transplant can give you healthy new marrow. You could need a transplant because of a disease,such as bone marrow diseases or cancers like leukemia kemia or lymphoma.Or you might need one if a strong cancer treatment kills your healthy blood cells.
People with cancer sometimes donate bone marrow before treatment to be transplanted later. But often the new marrow comes from a donor,either a close family member or someone unrelated.
The healthy cells for a transplant can come from three sources:bone marrow;peripheral (circulating) blood that has an increased number of healthy blood-forming cells(also called peripheral blood stem cells or PBSC);umbilical cord blood that is collected after a baby is born.
If you need an allogeneic transplant,your doctor will look for a marrow donor or cord blood unit that matches your HLA tissue type.HLA stands for human leukocyte antigen,a markei your immune system uses to recognize which cells belong in your body and which do not.
Before your body can receive the healthy cells,the diseased cells must be destroyed.This is done using chemotherapy and sometimes radiation. The destruction of diseased cells is called a preparative regimen or a conditioning regimen.
On the day of transplant,the cells from the marrow donor or cord blood unit are infused intravenously(go into your body through a large vein).These healthy cells move into the spaces inside your bones where they create new marrow. They grow and make healthy new red blood cells,white blood cells,and platelets.

The new marrow usually comes from__________.
A:people with cancer
B:a family member
C:an organ donor
D:a relative or a stranger

答案：D

解析：

细节题。第三段最后一句：通常新骨髓来源于一个捐献者，或者是血缘亲近的家人，或者是无血缘关系的陌生人。B不全面，C“器官捐献者”，也不正确。
词义推断题。第一段第二句：它包括不成熟的细胞，被称作干细胞。A是 “主要的”,B是“杰出的”,D是“重要的”，只有C是“发育不完全的”。
细节题。由第四段可以看出，A、C、D都是文章提到的，只有B"婴儿的血液”除外。
细节题。倒数第二段提到了生病的细胞一定要被破坏掉，A和B都是破坏的方式，都不全面。C意思不明，且与文义不符。D的意思是被彻底破坏掉。
推断题。A选项文章没有提及。C选项语气过于绝对，文章中没有如此说明。第三段第一句说癌症患者有时会在治疗前捐出骨髓用于日后的移植，D选项说必须，则是不正确的。从文章中可以看出，骨髓移植是很复杂的，因此B选项是可以推断出来的。

第6题：

There is an abundant supply of cheap labor in this country.

A:.a steady
B: a plentiful
C: an extra
D: a stable

答案：B

解析：

句意：这个国家有大量的廉价劳动力。steady和stable是近义词，都表示“稳定的”, 所以可以相互排除掉。再根据构词法：plentiful是“大量的”。故B项最合适。

A number of related causes may________(56)aging. Some cells of the body have a fairly long life,but they are not reborn when they die.As a person ages,________(57)of brain cells and muscle cells decreases.The other cells are replaced by new cells.In an aging person the________(58) cells and muscle cells may not be as viable（能生存的）or as capable________ ( 59 ) growth as those of a young person.

_________(51)
A:function
B:effect
C:fact
D:symbol

答案：B

解析：

本句话的意思是衰老导致死亡。所以，此处应选B项。
result in：导致，例如：Their dispute resulted in war．他们的争端导致了战争。与题意相符。因此，选择D。
由上下文可知此处应填入表示“人体器官”的词，选项A、B、C项均是人体器官中的一部分，器官的总称是organs，因此，选项D为正确答案。
protect against：保护……使其免受伤害，例如：Troops have been sent to protect aid workers against attack．已经派出部队保护援助人员免遭袭击。此处缺少的是名词，所以应填入protection
be likely to have accident：更易发生意外事件。
contribute to：导致、促成，例如：Your suggestion has greatly contributed to the accomplishment of our work．你的建议大大地促进了我们工作的完成。
选项B、C表示数量的多少，不能填到此处。most：表示大多数的意思，也不符合题意。因此，选项A为正确答案。
由于前句中提到死去的人体细胞被新的细胞所代替，因此，这句话一定是阐述新细胞的，因此，选项C为正确答案。
capable of：具有能力的，属于固定搭配，例如：Susan is capable of hard work．苏珊能胜任艰苦的工作。因此，选项C为正确答案。
这一段是和上一段平行的，都是谈论导致衰老的原因，选项C与题意相符，因此，为正确答案。
略
所选词和wrinkles保持时态一致，故选A。
由上下文可以推断出本句表示老人身高变矮，因此，只能填入A项。
此句是传递信息的意思，pass on：传递，例如：Would you pass it on to the next person？把它传给下一个人好吗？
传递是一个过程，因此，本句应填入选项D。
