某学校将为初一学生开设ABCDEF共6门选修课，现选取若干学生进行了“我最喜欢的一门选修课”调查，将调查结果绘制成如图统计图表（不完整）

根据图表提供的信息，下列结论错误的是（　　）

    We all fail,all the time.We might miss a call with a client because of an emergency work meeting,or miss that meeting because another project has suddenly become urgent.And then we (or our families) get sick,and we have to shift priorities around again.

    These unsystematic failures are benign,though.They reflect that all of us have limited resources.There simply is not enough time,energy,or money,to do everything you want to do all the time.Part of being a responsible adult is learning to make trade offs: balancing your conflicting goals and trying to get as much done as you can in the time you have.

    The thing you really need to watch out for is the systematic failure.The systematic failure happens when there's a particular goal you want to achieve,but never get to.The causes of systematic failures usually boil down to some combination of these three factors:

    1).Short-term pressures versus long-term goals.Most of us prefer to achieve pressing short-term goals rather than put time into long-term projects.Lots of research suggests that our brains are wired to prefer tasks that pay off in the short term rather than those whose benefit is long-term.The people who do manage to accomplish their long-term goals create regular space to make progress on them.

    2)._________Without even realizing it,we often do what is easiest to accomplish rather than what we say is most important.Email is a great example.If you are like most people,you keep your email program open at work all day. Consequently,each new message is an invitation to drop what you are working on to check it.It feels like work and it's much easier than finishing that 100-slide presentation.Simply shutting off email for a few hours a day can remove this source of distraction from the environment.

    3).Working for too long.Many workplaces create pressure to stay at the office for more and more hours,which (paradoxically) creates opportunities for systematic failures.Work is not an iron man competition where the last person there wins.Most people have an optimal（最佳的）number of hours they can work each day.For example,I can be productive at work for about 8-9 hours a day.If I spend any more time at work than that,then at some point,I start doing "fake work."

    The next time you run into trouble,assess whether it's an unsystematic failure or a systematic one.When you notice a systematic failure in your life,you need to make a change in your behavior.If you don't make a change,you will continue to fail.

    Finally,if you experience a lot of unsystematic failures,it might be worth rethinking the number of tasks you are taking on.Perhaps you need to offload some responsibilities onto someone else,before you start experiencing more systematic failures.

如图所示，水平传送带以速度v₁匀速运动，小物体P、Q由通过光滑定滑轮的不可伸长的轻绳相连，t=0时刻P在传送带左端具有速度v₂，已知v₁>v₂，P与定滑轮间的绳水平。不计定滑轮质量，绳足够长，物体与传送带之间的最大静摩擦力和滑动摩擦力相等。从最初直到物体P从传送带离开的过程，以下判断正确的是（    ）

阅读下列四篇短文，从每小题后所给的A、B、C、D四个选项中，选出最佳选项，并在答题卡上将该选项涂黑。

    Elvis Presley,who was one of the most popular American singers of the twentieth century, made the Rock & Roll music popular around the world. He sold millions of records and made many successful films, and he helped change the direction of popular music in the 1960s.

Elvis Presley was born in a poor family in 1935. His parents were simple country people who often took him to church, where he learned to sing and he never forgot the kind of songs that he used to sing in church as a child.

    When he was a teenager, Elvis moved from Tupelos to Memphis in Tennessee, where he attended high school, but he was not a good student. His only real interest was singing. He began to sing in the style that is called “country and western”.

    In 1955 he recorded some songs for his mother's birthday. The people at the recording studio liked his singing and his music. There was something different about it. It was country and western music, but it also sounded a little like the music, which black people used to sing in the American South, music kn own as “blues”.

   Shortly after that, Elvis met Tom Parker, who became his manager and arranged(安排)concerts for him across the United States and new recordings as well. Soon Elvis rose to fame all over the country. Later, Elvis went to Hollywood and began to appear in films like Love Me Tender and King Creole.

    But Elvis found it hard to live with success, like many other entertainment personalities (娱乐圈内的人士). He began to take drugs and his health began to suffer. When he died at an early age of 42 in 1977, his many millions of fans were shocked. “The King Is Dead!” the newspaper said. But today his memory and his music live on and he will always be remembered as the King of Rock & Roll.
