请认真阅读下列短文,根据所读内容在表格中填入一个最恰当的单词.
Ambition is a necessary quality in life.It is the force which drives us on to use whatever talent we have got.If we haven’t got some degree of ambition,these talents will not be used for our own and other’s benefit.We must continually want to be better than we are.Without ambition we are just jellyfish that flop through life.We only react to events; we don’t try to control them.
Ambition,however,can have several defects.
First of all it can be unrealistic.We may not be able to see the limits of our own abilities,so we do ambitious things that are completely beyond us.Our career masters can see our good qualities and our limitations objectively.They may tell us that we haven’t the ability to deal with people and would make good businessmen.We refuse to take their evaluation.We keep on trying.Many years and many disappointments later we are forced to accept their judgment.But what a waste of time our ill-founded ambition has caused us!
Too 75.____________ ambition may cause us to devote our attention to one narrow aim,lacking the breadth of view necessary for 76,____________ success.
Our ambition may make us among those 77._____________ people who gain their interests by sacrificing others’.
Our ambition can be 78.____________ to lifeless aims,which lead us to the way to build up our 79.____________ through possessions of artificial signs of worth.
Conclusion
Ambition is a good servant but a bad 80.____________.Therefore,we must try to direct it in a proper way.
Ambition better benefiting Unrealistic concentrated
greater selfish limited reputation/fame master
其中：master 和 selfish 从文章哪里能找到?

77.selfish ."people who gain their interests by sacrificing others’."这句话意思是通过牺牲他人的利益来获得自己的快乐,这类人就是自私的人,所以是selfish
80.master,题干中说Ambition is a good servant,但是后面的“but”又转折了,说明后面的空格需要填与servant相对的词,就是master了.
我觉得文章只是简单介绍了ambition,而回答问题更多需要题干来理解,希望这些对你有所帮助
