1 试题题型：未知难度等级： Leadership is the art of getting someone to do something you Leadership is the art of getting someone to do something you want done because he wants to do it. People naturally want to follow a good leader. After meeting with an effective leader it is not unusual to feel uplifted(情绪高涨), inspired, and motivated to work towards a common goal. An effective leader makes others feel good about themselves, as well as the work they are doing. The leader has a vision(幻想)of what he or she wants to achieve, and can communicate that vision to others in a way that makes people want to be part of it. One thing a good leader typically does is to communicate the big picture, so that each employee can see how the particular role he or she plays makes a contribution to the final result. Good leaders are positive and optimistic when they speak about the future. Their enthusiasm wins them plenty of supporters who help make their vision a reality. Good leaders also understand that different people are motivated by different things. For employees motivated by a need for achievement, a leader explains how the task offers an opportunity to take on a challenge with an achievable goal. And employees are motivated by hearing how they will be part of a team of people working together. Good leaders will introduce employees by name first, rather than job titles. They refer to employees as team members, companions, or colleagues, never as “servants”. Words have power, including the power to make people feel whether or not they are important to the success of an organization. Good leaders believe that every team member matters and set up environments that make everyone feel important. It is no wonder they can attract the support they need to help them achieve their goals. 小题1:What’s the author’s purpose of writing this passage A．To tell us how to be a good leader at work.

B．To draw a beautiful picture of the employee’s future. C．To encourage the employee to meet the challenges of his work. D．To let the staff know the important role the employee plays. 小题4:We can infer from the passage that_________. A．a good leader is always good at creating comfortable working conditions B．the support of employees is necessary for a leader to reach his goal C．names are much easier to remember than job titles D．the motivation of the employees all comes from the leader
2 试题题型：未知难度等级： President Barack Obama has complained about the loss of priv President Barack Obama has complained about the loss of privacy that comes with being leader of the United States, regretting the loss of simple pleasures such as a long walk or a trip to the car wash or supermarket. "I just miss – I miss being unknown," he said. "I miss Saturday morning, rolling out of bed, not shaving, getting into my car with my girls, driving to the supermarket, squeezing the fruit, getting my car washed, taking walks. I can't take a walk." His dream, he said, was to "go through Central Park and watch folks passing by ... spend the day watching people – I miss that". Faced with criticism for playing more golf than most previous occupants of the White House, he explained that the sport was simply the best way of getting relaxed. "It's the only excuse I have to get outside for four hours," he told Hearst magazines. Though he said he enjoyed his life in the White House, he felt disillusioned（醒悟的，幻想破灭的） with the some of the ways of Washington, which he has failed to change, such as the "kabuki dance（日本歌舞）" among political parties before serious policy discussions begin. His comments may be seen as excuse by critics who have accused him of appearing too detached（漠然）, and being slow to engage in important issues such as Libya and the near shutdown of the US government last week. Since arriving at the White House in January 2009, Mr Obama has already racked up（打）60 rounds of golf in office, more than George W Bush did in his eight years. In terms of ability, Golf Digest magazine has ranked Mr Obama eighth out of the 18 presidents who played the game since it became established in the early 20th century. 小题1:What do the second paragraph and the third paragraph mainly tell us . A．Obama wishes to enjoy simple pleasures. B．Obama likes going shopping with his girls. C．Obama likes to take a walk. D．Obama likes to watch folks passing by. 小题2:According to Obama, he plays golf to ___________. A．avoid criticism B．show his ability C．get relaxed D．show his advantage over the former presidents 小题3:What does the underlined word “It” refer to in the fifth paragraph A．Playing golf. B．Getting relaxed. C．Changing some ways of Washington. D．Watching people 小题4:What is the best title of the passage A．Obama complains about lack of privacy as president B．Obama can’t live a normal life C．Obama is often criticized D．Obama likes to play golf
3 试题题型：未知难度等级：请阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该选项的标号涂黑。Humans a 请阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该选项的标号涂黑。 Humans are naturally drawn to other life forms and the worlds outside of our own。We take delight in the existence of creatures and even whole societies Beyond our everyday lives. This sense of wonder is universal. Look at the efforts that scientists（幻想）literature or movies like the lord of the rings. This sense of wonder draws us to each other，to the world around us ,and to the world of make-believe.but have we gone so far in creating worlds of fantasy that we are missing the pleasure of other worlds that already exist all around us Human beings，as biologists have suggested，possess an inborn desire to connect with and understand other life forms，However, people，especially in big eities，often lead rather isolated lives，In a study of British schoolchildren，it was found that children by age eight were much more familiar with characters from television shows and video games than common wildlife.without modem technology，a small Pond could be an amazing world filled with strange and beautiful plants，insects，birds，and animals 。when we lack meaning（交互）with the world around us,and somethings even with our families and friends，we seek to understand and communicate with things that exist only in our imaginations or on a computer screen。 The world of make-believe is not necessarily bad,but when the world of fantasy becomes the only outlet（出路）for our sense of wonder，then we are really missing something，we are missing a connection with the living world. Other wonderful wonderful worlds exist all around us.but even more interesting is that if we look closely enough，we can see that these worlds,in a broad sense,are really part of our own. 小题1:The popularity of the lord of the rings.proves A．the close connection between man and the fantasy world B．the wonderful achievements of fantasy literature C．the fine taste of moviegoers around the world D．the general existence of the sense of curiosity 小题2:What can we infer from the underlined sentence in Paragraph 3 A．people are far less familiar witn the world of fantasy B．the world around us could serve as a source of wonder C．the world of fantasy can be mirrored by a small and lively pond. D．Modern technology prevents us from developing our sense of wonder 小题3:If our sense of wonder relies totally on the world of make-believe,we will A．fail to appreciate the joy in our lives B．be confused by the world of make-believe C．miss the chance to recognize the fantasy world D．be trapped by other worlds existing all around us 小题4:What is the main purpose of the passage A．To show us the hidden beauty in our world. B．to warn us not to get lost in the fantasy world. C．To argue against the misuse of the sense of wonder. D．To discuss the influence of the world of make-believe.
