(用于另一事物)考点三：易错点解析1.我提不出比这更好的建议。
【误】I am unable to improve the suggestion.【正】I am unable to improve on the suggestion.【析】improve用作及物动词,表示“改善或改进”。
如表示“作出比…更好的东西”,应该说 improve on〔upon〕…,此时, improve是不及物动词。
2.我们希望改进我们的工作。
【误】We wish to improve our work better.【正】We wish to improve our work.【析】improve的意思是“改进,使更好(make better)”,已包含better之义,再加上个better,即属赘余。
3.你认为这个形势得到改善了吗？【误】Do you think the situation is improved?【正】Do you think the situation is improving?【析】句中的形势改善应是一种主动语态，这不可用improved。
