1. aren't allowed, before ( until), is filled in (up) / are allowed, after, is filled in (up)。其中not…until / before…意为“直到……才”。
2. With his help, great progress.表示“在某人的帮助下”用with sb's help或with the help of sb.注意:用的是介词with(由于)而不是under(在……的下面)。“取得进步”是make progress,其中progress是不可数名词。
3. it / it's; possible.填it possible,it是形式宾语,真正的宾语是to finish…,possible是宾语补足语;若填it's possible,it's possible to finish the work tomorrow是宾语从句,it在从句中作形式主语,to finish…是真正的主语。
