    參考答案及解析:
    1. most→ rest：根據(jù)上下文，應(yīng)表達“除了上學(xué)以外的時間”。
    2. while→ when / if ：邏輯分析，此處應(yīng)為假設(shè)的時間關(guān)系，不是簡單的同步時間關(guān)系。
    3. inside→ outside：根據(jù)上下文的意思，應(yīng)該是“越來越多的母親在外面工作”
    4. 在stop后加by：stop by表示途中短暫的訪問，歇腳，休息等;符合下文的 temporarily in the midst of a busy schedule of activities。
    5. 在then和a之間加to：與上文的go to關(guān)聯(lián)，實際為 children go to school and then (go to) aseries of highly-programmed after-school activities.
    6. 刪除face后的with：此處face為及物動詞
    7. have→ create：have表示“擁有，存在”，create強調(diào)“出現(xiàn)，產(chǎn)生，引起”。此處是指因為假期而引起和出現(xiàn)照料孩子的問題
    8. many→ no/ few：根據(jù)上下文邏輯分析，幾乎沒有可以供孩子到處玩樂的街區(qū)存在。
    9. from→ in：result from意思是“起因于”，result in意思是“其結(jié)果是........”
    10. look→ looking：現(xiàn)在分詞短語做定語，修飾both parents and children
