     The average adult has about five litres of blood living inside of their body, flowing through their vessels

(血管), delivering essential elements, and removing harmful wastes. Without blood, the human body would

stop working.

     Blood is the fluid of life, transporting oxygen from the lungs to body tissue and carbon dioxide from body

tissue to the lungs. Blood is the fluid of growth, transporting nourishment from digestion and hormones from

glands (腺) throughout the body. Blood is the fluid of health, transporting disease fighting substances to the

tissue and waste to the kidneys (肾脏).

     Because it contains living cells, blood is alive. Red blood cells and white blood cells are responsible for

nourishing and cleansing the body. Since the cells are alive, they too need nourishment. Vitamins and Minerals

keep the blood healthy. The blood cells have a definite life cycle, just as all living organisms do.

     About 55 percent of blood is plasma (血浆), a straw-coloured clear liquid. The liquid plasma carries the

solid cells and the platelets (血小板), which help blood clot. Without blood platelets, you would bleed to death.

     When the human body loses a little bit of blood through a minor wound, the platelets cause the blood to

clot so that the bleeding stops. Because new blood is always being made inside of your bones, the body can

replace the lost blood. When the human body loses a lot of blood through a major wound, that blood has to

be replaced through a blood transfusion from other people.

     But everybody's blood is not the same. There are four different blood types. Plus, your blood has Rh

factors, which make it even more unique. Blood received through a transfusion must match your own.

Patients who are scheduled to have major surgery make autologous blood donations (donations of their own

blood) so that they have a perfect match.

1. The blood can do the following except ____.

A. deliver essential elements for the body

B. remove harmful wastes from the body

C. absorb oxygen from the air to body tissue

D. move carbon dioxide from body tissue to the lungs

2. Which of the following is the least related to blood's role?

A. Life.

B. Growth.

C. Health.

D. Waste.

3. What is the function of the liquid plasma?

A. It is a straw-coloured clear liquid.

C. It gives the blood cells a definite life cycle.

D. It helps the blood clot so that the bleeding stops.

生命不同于无机物质，它既遵从物理化学的基本规律，又有着自身独特之处。任何生命都毫不例外地有着十分微妙的结构体系。它的结构与行使的功能无比协调，在部分和整体之间，不同层次之间，不同组织之间，都保持着有条不紊的相互关系，由小秩序组成大秩序，并能够对周围环境的变化作出确切反应，进行合成和分解代谢。而在上下两代间，则通过互补复制，维持了物种的持久性和可变性。现在知道，正因为这一系列非凡复杂的分子组合特点，才表现出了无比微妙的生命属性。
以上文字主要强调的是( )。

A．生命遵循着物理化学的基本规律
B．生命具有非凡复杂的分子组合特点
C．生命本身具有独特性
D．生命有持久性和可变性
