6．Does stress cause gray hair？Many people believe that tension and stress can cause your hair to lose its color．In fact，it is an old wives tale that being upset all the time can result in premature graying．Here is a closer look at this situation and why some believe that this old wives tale could be true．
As one ages，the hairs on the head also age．In fact，just about everything on the human body begins to show signs of wear and tear after a while．The joints wear become stiff and skin wears and becomes wrinkled．Hairs on the head grow and eventually die．They are replaced，but in the process something else happens．
When new hairs are replaced，the color or pigment（色素）is also added to them．However，as one ages，this pigment becomes less and less available．At first，hairs will have a limited amount of pigment and they will appear to be grayish in color．In time，they will lose all of their pigment and will be white．Many things are known to cause graying and genetics is a very powerful factor．If one of your parents turns gray at an early age，there is a good chance that you will too．Some people begin the graying process in high school，while others may be over the age of forty．
Constant worry and tension can have many harmful effects on the human body．It is a known fact that stressful times can cause one to suffer hair loss．It would make sense that if it can cause these problems，perhaps it also may contribute to graying．However，there is no sound evidence to support this．
On the other hand，many medical professionals believe that there may be a link：between graying and a constant state of anxiety or tension．Does stress cause gray hair？There is no scientific evidence to support the theory，but it is best to avoid stressful situations．
24．The underlined phrase in the first paragraph most probably meansA．
A．silly remarks               
B．clever remarks
C．exciting remarks            
D．disappointed remarks
25．The second paragraph mainly tells usC．
A．every part of body is replaced with age     
B．hairs will grow weak but not die
C．every part of body ages with age         
D．skin becomes wrinkled with age
26．From the passage we can infer thatD．
A．sound evidence has been found．
B．gray hair has nothing to do with tension．
C．stressful situations can be of benefit．
D．stress causing gray hair is still in question．
27．What might play the most important role in the graying process？B
A．Genetics and the amount of sleeping time．
B．The amount of pigment and genetics．
C．The amount of food people eat and living environment．
D．Genetics and the amount of water people drink．

2．In my profession as an educator and health care provider，I have worked with numerous children infected with the virus that causes AIDS．The relationships that I have had with these special kids have been gifts in my life．They have taught me so many things，but I have especially learned that great courage can be found in the smallest of packages． Let me tell you about Tyler．
Tyler was born infected with HIV：his mother was also infected．From the very beginning of his life，he was dependent on medications to enable him to survive．When he was five，he had a tube surgically inserted in a vein in his chest．This tube was connected to a pump，which he carried in a small backpack on his back．Medications were hooked up to this pump and were continuously supplied through this tube to his bloodstream．At times，he also needed supplemented oxygen to support his breathing．
Tyler wasn't willing to give up one single moment of his childhood to this deadly disease．It was not unusual to find him playing and racing around his backyard，wearing his medicine-laden backpack and dragging his tank of oxygen behind him in his little wagon．All of us who knew Tyler marveled at his pure joy in being alive and the energy it gave him．Tyler's mom often teased him by telling him that he moved so fast she needed to dress him in red．That way，when she peered through the window to check on him playing in the yard，she could quickly spot him．
This dreaded disease eventually wore down even the likes of a little dynamo like Tyler．He grew quite ill and，unfortunately，so did his HIV-infected mother．When it became apparent that he wasn't going to survive，Tyler's mom talked to him about death．She comforted him by telling Tyler that she was dying too，and that she would be with him soon in heaven．
A few days before his death，Tyler beckoned me over to his hospital bed and whispered，"I might die soon．I'm not scared．When I die，please dress me in red．Mom promised she's coming to heaven，too．I'll be playing when she gets there，and I want to make sure she can find me．"

64．What is the boy Tyler's attitude towards death？B
A．pessimistic．     B．optimistic．
C．sorrowful．       D．fearful．
65．Tyler requested the writer to dress him in red when he died simply becauseC．
A．red is a lucky color           
B．red might help to cure him
C．his mom could spot him easily  
D．he could find more mates by wearing red
66．Which of the following might serve as a possible title for this passage？D
A．My unusual profession．     B．A caring mother．
C．Mother and son．            D．Dying in red．
67．The underlined word dynamo in the fourth paragraph here meansB．
A．a(chǎn) promising and helpful youth
B．a(chǎn)n extremely energetic person
C．a(chǎn) rare and beautiful flower
D．a(chǎn) magic and understanding superstar．
