根据短文内容,从下框的A～F选项中选出能概括每一段主题的最佳选项,选项中有一项为多余项。
A.Not allow weaknesses to limit one's possibilities.
B. An example of a successful person.
C. Overcome one's significant limitation.
D. The interaction between one's strengths and weaknesses.
E. Many successful people with weaknesses.
F. The power of weakness.
1.________
     We all have weaknesses and strengths-no matter who we are. Sometimes the weaknesses seem to
outweigh the strengths and sometimes it's the other way around. Some people get sick easily. Some
struggle to manage their finances properly. Some people are hopeless communicators and struggle with
relationships.
2. ________
     Many people leave it and accept it as just bad luck-but not everyone. Some people facing huge
limitations still manage to achieve tremendous things. They rise above their weaknesses and do not allow
them to limit their possibilities.
3. ________
     I attended a school prizegiving ceremony not so long ago and the guest speaker was Andrew
Becroft, who had a severe stutter(结巴) as a child. Instead of allowing this to limit him, he chose to work
hard to overcome it. He is now the Principal Youth Court Judge for New Zealand. Not only did he
become successful, but he did so in a profession where he had to speak in front of others
regularly -where his weakness is front and center for all to see. If he hadn't worked on his speaking
ability, it would have been very limiting to his life and career prospects.
4. ________
     You can find similar people on New Zealand News channels, and I suspect the same in other
countries. There are a number of presenters and reporters who have a noticeably unusual manner of
speaking. Perhaps they have a lisp(咬舌), or they have a strange accent or pitch of voice. These people
have succeeded in spite of what would be appear to be a weakness in their profession.
5. ________
     Lots of people face far more significant limitations than you do. They may be missing limbs or are born
into extreme poverty. But no matter what the limitation, you will always find people who have overcome
it.
