Suppose you will go blind 3 days later? How would you spend those 3 precious days? What would you see before going into darkness forever?

    I should want {#blank#}1{#/blank#} (much) to see the things which have become dear to me through my years of darkness. I should want to see the people whose {#blank#}2{#/blank#} (kind) and company have made my life worth {#blank#}3{#/blank#} (live). First I should like to stare long{#blank#}4{#/blank#} the face of my teacher, Mrs. Anne Sullivan Macy, who came to me when I was a child and {#blank#}5{#/blank#} (open) the outer world to me. I should want not merely to see the outline of her face, so that I could cherish {#blank#}6{#/blank#} in my memory, but to study that face and from it find the evidence of the love and patience with {#blank#}7{#/blank#} she accomplished the difficult task of my education. I should like to see in her eyes that strength of character which has enabled her to act {#blank#}8{#/blank#} (brave) in the face of difficulties, and that sympathy for all humankind {#blank#}9{#/blank#} (show) to me so often.

    Oh, those things above would be the things that I should see if I {#blank#}10{#/blank#} (have) the power of sight for just 3 days!

When talking about our bodies, we often forget our skin. Actually, our skin is very important, too. It keeps us{#blank#}1{#/blank#}(inform) of the outside world--{#blank#}2{#/blank#}it is hot or cold, wet or dry.

Try this: pull up the skin from the back of your hand and then let {#blank#}3{#/blank#}go. What happens?

The skin goes back to its first position, which means that skin is elastic (有弹性的).

Our skin seems to be very thin, but it {#blank#}4{#/blank#} (make) up of two layers. The top layer is the one we wash every day. Do you know that this part of skin is dead? However, it is still very important because it serves as{#blank#}5{#/blank#} (protect) against dirt and disease.

Skin has millions of tiny holes called pores(毛孔). Pores allow liquid, especially sweat,{#blank#}6{#/blank#}(pass) through. By{#blank#}7{#/blank#} (sweat), our bodies keep up a normal temperature. When it is very hot, we sweat a lot, but{#blank#}8{#/blank#}(strange) enough, when it is quite cool, we also sweat. On a cool day, our bodies produce {#blank#}9{#/blank#}average of 700 ml of sweat. That is{#blank#}10{#/blank#}(much) than 0.5 kilos.
