| Live with disability is frustrating and challenging. Everyday activities are more difficulty than they are for others. It is also often disappointed to find that other people do not feel comfortable together with someone who are disabled. Perhaps we should all listen Xiaowen's advice. "Sometimes I wonder why they call myself disabled," she says. "I have learnt to live with my body as it is and adjust my way of life." Maybe it is time for the rest of society accept me as I am and get used to the fact which while I may not be able to walk, there are many the other great things I can do." | 1. ______ 2. ______ 3. ______ 4. ______ 5. ______ 6. ______ 7. ______ 8. ______ 9. ______ 10. ______ |
