1.如果你不更加努力,你永远也不会取得成功（push....hard） 2.你是不能用价钱来衡量父母对孩子的付出（put a price on） 3. 弗雷德业余时间大部分用在了收集旧车并把它们恢复原样上面（a good amount of ，restore） 4.威廉是一个成熟且有责任心的教育工作者,他对学生充满信心（have faith in） 5.家长们必须记住，如果他们老是批评孩子，他们是不能指望孩子建立自信心的（bear in mind ，be critical of） 在线苦等啊
急你所急。大可放心。 1. If you don't push harder, you will never succeed. 2.One cannot put a price on what parents have contributed to their children. 3. A good amount of Fred's spare time has been spent on collecting used cars and restoring them to what they once were. 4. As a mature and responsible educator, William has full faith in his students. 5. Parents should bear in mind the fact that if they are always critical of their children, they can't expect the latter to build up their self-confidence. 注：其中the latter取代了them,以跟前面指父母的they区别开来。是很地道的用法。
