阅读下面短文，掌握其大意，从每题所给的A、B、C、D四个选项中，选出最佳选项。
Alice, my friend’s daughter, goes to an expensive private school where she has a friend, Jane, who is on a full scholarship at this school. Jane has   36  economic resources—her father has been dead for years and her mother works   37  a maid. Although her mother works very hard, she can       38 __ support the family. Jane is very bright and gifted at   39  and that’s how she has got the scholarship, which included a(n)   40  for things like lunch, school uniform and music lessons.
Alice became friends with Jane and would   41  talk to her at lunch. She did it that way in order to avoid the other kids   42  her.
On her birthday last month, she   43  her new friend to her birthday party, but Jane said she couldn’t come. Alice wanted her to be   44  so much that she   45  on her coming. Eventually, the girl said, “I don’t have any   46__ clothes that I could wear at your birthday party.” After a brief pause, the girl remembered, “I have a   47  from my piano performance,” and asked, “Could I   48  a skirt from you?”
Alice was happy that her friend would be   49  to come and hurried home to ask her Mum    50  she could lend her friend one of her skirts. To her surprise, her Mum said, “No.” The daughter was very   51  and angrily said to her Mum, “   52  I could, I would give my friend all my clothes.” The Mother didn’t understand why her daughter should have had such an outburst as she’s normally very well   53  .
Finally, Alice explained to her Mother her friend’s   54  .  Her Mother immediately changed her mind and said, “Yes.” She also encouraged her daughter not to feel like she should secretly be friends with Jane but to feel proud of her   55  with her.
So the true friendship seeks to give, not to take; to help, not to be helped; to minister, not to be ministered to.
