Sometimes I really doubt whether there is love between my parents. Every day they are very busy trying to  26  in order to pay the high tuition for my brother and me. They don’t act in the  27  ways that I read in books or I see on TV. In their opinion, “I love you” is too  28  for them to say. Sending flowers to each other on Valentine’s Day is even more out of   29  .

One day, my mother was sewing a quilt. I sat down beside her. “Mom, I have a question to ask you. Is there  30  between you and Dad?” I asked her in a very low voice. She didn’t answer immediately. She  31 her head and continued to sew the quilt.

I was very worried because I thought I had  32  her. I was  33  and I didn’t know what I should do. But at last I heard my mother say the following words:

“Susan,” she said thoughtfully, “Look at this thread．Sometimes it  34  , but most of it disappears in the quilt. The thread really makes the quilt   35  . If life is a quilt, then love should be a thread．It can hardly be seen     36  , but it’s really there. Love is  37 .”

I listened carefully but I  38  her until the next spring. At that time, my father suddenly  39  seriously. My mother had to stay with him in the hospital for a month. When they returned from the hospital, they both looked  40 . It seemed both of them had had a serious illness. After they were back, every day in the morning and dusk, my mother helped my father   41  on the country road．

“Dad, how are you feeling now?” I asked him one day.

“Susan, don’t  42  me.” he said gently. “To tell you the truth, I just like walking with your mom.”  43  his eyes, I know he loves my mother deeply.

Once I thought love meant flowers, gifts and  44 . But from this experience, I understand that love is just  45  in the quilt of our life. Love is inside, making life strong and warm.

The whole body is covered with skin.The surface of the skin is dead(like the hair and the nails),but it is made from a living layer(层)just under the surface.The outside dead layers wear off(磨损)all the time,with new ones replacing them,and the body forms a totally new skin every three weeks.

The skin protects the body from the outside world and it passes information from the outside.It helps to keep water in the body and to keep the body at the same temperature.Becteria(细菌)can’t get in through the skin unless it is damaged.

If the weather is cold,the blood vessels(血管)in the skin squeeze down,or contract(收缩),so that as little blood as possible comes near the surface.This means that less warmth is lost to the outside.This makes the skin look pale,or even “blue”.At the same time,the hairs on the skin are pulled upright by tiny muscles.

When it is hot,the blood vessels expand(扩大),or get wider again,to allow plenty of blood to run near the surface of the skin.This helps the body to lose heat,and the skin may look red.At the same time,the sweat glands(汗腺)produce more sweat,which cools the skin.

If your skin has ever been numb(麻木的),you will realize how important the feeling from the skin is.Nerves(神经)in the skin are sensitive(敏感的)to heat and cold,sharpness,hardness and softness,wetness and dryness and pain.If one is not able to feel these things,which can act as warnings,he is likely to be burned,cut or hurt in other ways.

The colour of the skin depends on special colour cells(细胞).These are just below the top layers of the skin.They are needed as protection from some harmful ray of the sun.The stronger the sun is,the more important it is to have a dark skin.People with pale skins may “tan”(晒黑)in the sun.This happens when the body produces extra colour cells in the skin for protection.In the sun,the skin produces a vitamin(vitamin D)which is needed for strong bones.
