     It doesn't have to be war. But sometimes, it is. As the caretakers of the family, mothers mainly control the

family's course through the trouble of their daughters' adolescent (青春期的) years. As such, they often feel it

their duty to make sure that each member survives and grows stronger. As a result, mothers often feel a greatly

increased burden (负担 ) during their daughters' adolescence.

     It's far from easy to live with someone who is experiencing rapid changes in how she looks,thinks and feels. Mostly, girls' changing bodies usually make their mothers uncomfortable. Just when girls are turning into

shapely young women, mothers are often in or near midlife. It may be difficult to live with adolescent daughters who remind them of their ever diminishing (减少的 ) youth.

     Mothers mainly describe feeling scrutinized (细察) by their teens. As one mother put it," Living with my

daughter is like having my own personal X-ray machine." This is because your daughter's effort to develop her

own individuality (个性) drives her to examine your every action. This is totally different from her early

childhood, when you often could do no wrong or were the"best mother in the world".

     Some women have a hard time dealing with trouble, so their teenage daughters' challenging behavior is

particularly unwelcome. Thinking back to when your daughter was a little girl, you probably expected her to

get into quarrels with others. Since your daughter has reached adolescence, you may believe that your daughter

should be beyond all that. She should know how to get along with people-especially with you.

     Remember that this period passes, and mothers and daughters often end up close friends. But for now,

you're the adult, so enjoy the sufferings.
