洋枪队统领华尔被太平军击毙于（    ）

   George liked flying a plane. Once he bought a small plane and learned how to fly it. He soon became so good that he could make his plane do all kinds of tricks（技巧）.
   George had a friend. His name was Peter. One day George said to his friend, “ Peter, would you like to have a trip in my plane?” Peter thought, “ I’ve traveled in a big plane several times, but I’ve never been in a small one, so I’ll go.”
   They went up, and George flew around for half an hour and did all kinds of tricks in a shaken voice（颤抖的声音）, “ Well, George, thank you very much for these two trips in your plane.”
   George was very surprised and asked, “ Two trips? ”
   “Yes, my first and my last.” Answered Peter.

下列有关叙述中一定正确的是（   ）

    If something that you’re doing doesn’t challenge you, then it doesn’t change you. We all need some normal stress in our lives, after all____ So challenge the following limits:

    Figure out what you’re scared of and do it continuously.

If you're a salesman，and you're scared of talking to people personally or over the phone, now, instead of being scared and thinking you’ll fail, spend at least five minutes a day to pick up the phone and make a call.____ But don’t stop on the first try! Eventually, you can look at fear in the eyes and say, “Go on, I'm not scared!”

    ____

    Make sure this hobby is not linked to your career; you have to relax and relieve your stress while performing this. Some examples might be cooking, sewing, painting and so on. Apart from helping you challenge yourself, taking a class for your hobby may also give you extra income.

    Set aside at least nine minutes a day for physical exercise.

    ____A simple 9-minute run around your neighborhood can do wonders for yourself. Exercise can not only help you maintain your regular weight, but also make feel better about yourself.

    Travel and allow yourself to be interested in new people.

    Don't just limit yourself to your fellow travelers-try to connect with the service staff. You never know what kind of people they're going to be. Get out of your house or go online right now to book your class.____
