2. One possible version:
   Student Union,
      National Aid to the Disabled Day is the day for us to do something for disabled people
  who are still one of the special groups that need help most in society. As this special day

  is around the comer, I am writing to ask you to consider the following things.
  ①Go on diet for one day. It seemed not proper for us to have a lot of food, while

    quite a lot of disabled people lead a poor life in our city. we should give up all the

    junk food to raise money to help the disabled.
  ②Pay a visit to the disabled. As we know the disabled may feel helpless and frustrated
    sometimes, if we can pay them a visit, we can make them feel the warmth of our big so-
    cial family. We can take some small gifts and help them with the housework when we
    visit them.
  ③Have fund-raising activities on City Square. Many disabled people have difficulty

    in making money, so we should think of ways to collect money to help them. It is a good
    idea to organize different kinds of activities on the City Square to collect some money.
    The activities may include selling our secondhand books, holding dancing or singing
    parties and so on. We can invite some disabled people to join us.
  ④Organize one-yuan donation activities in school. We students still depend on our
    parents for money, but we can persuade every student to donate one yuan to help the
    disabled. Though one yuan is a small amount, it can improve our awareness in doing
    charity work through our involvement.
  ⑤Hold special class meetings. While there may be better ways to help the disabled, we.
    should also put ourselves in their shoes and think about how life is like for the

    disabled. Through class meetings, we can discuss the difficulty the disabled might face

    and the measures we and the society can take to help them.
    Thank you for reading my letter. I hope you will consider my suggestions. Disable peo-
ple need help, so on this special day we should do something to show that we are concerned
about them and make more people know their problems.
                                                                      Yours Sincerely,
                                                                        Your Name
