(2010届合肥一六八中学高三年级第二次段考)

In addition to self?awareness, imagination, and conscience, it is the fourth quality-independent will- that really makes effective self?management possible. It is the ability to make decisions and choices and to act in agreement with them. It is the ability to act rather than to be acted upon, to actively carry out the program we have developed through the other three qualities.

The human will is an amazing thing. Time after time, it has overcome unbelievable difficulties. The Helen Kellers of this world give dramatic(给人深刻印象的) evidence to the value, the power of the independent will.

But as we examine this quality in the context of effective self?management, we realize it’s usually not the dramatic, the visible(可见的), the once?in?a?lifetime, up?by?the?bootstraps(自立自强的) effort that brings lasting success. This special ability comes from learning how to use this great quality in the decisions we make every day.

The degree to which we have developed our independent will in our everyday lives is measured by our personal honesty. Honesty is, fundamentally, the value we place on ourselves. It’s our ability to make and keep promises to ourselves, to “walk our talk”.

Effective management is putting first things first. While leadership decides what “first things” are, it is management that puts them first, day?by?day, moment?by?moment. Management is discipline (training to be self?controlled), carrying it out.

Discipline obtains from belief-belief in a set of values, belief in an overriding(最主要的) purpose, to a long?term or short?term goal that must be carried out.

In other words, if you are an effective manager of yourself, your discipline comes from within; it is a function of your independent will. You are a follower of your own deep values and their source. And you have the will, the quality to control your feelings and moods rather than depend on others or have your work half done.

答案：1. effective　2. prove/show/indicate　3. decisions　

4. Honesty　5. kept　6. what　7. stick　8. Conclusions　9. follow　

10．We are looking forward to________a chance to watch the opening ceremony of the London 2012 Olympic Games.

A．give　 　　　　　　　　B．be given

C．being given　 　　　　　D．giving

解析：选C。句意：我们期望有机会看到伦敦2012年奥运会的开幕式。look forward to后面要跟动名词形式，根据语境可知要用被动形式，故C项正确。

9．The headmaster told the boy________the angry teacher，but he refused to.

A．to apologize　 　　　　B．apologize to

C．to apologize for　 　　　D．to apologize to

解析：选D。考查动词用法。tell sb.to do sth.告诉某人做某事；apologize to sb.(for sth.)(因某事)向某人道歉。

8．Sir，you are not allowed to enter the building if you don’t get our manager’s________.

A．permission　 　　　　B．connection

C．instruction　 　　　　D．introduction

解析：选A。考查名词辨析。permission允许，许可。句意：先生，如果没有我们经理的允许，你不准进入这座大楼。connection连接，关系；instruction指示，说明；introduction介绍。
