任务型读写。
阅读下面短文,根据所读内容在表格中的空白处填入恰当的单词.注意:每个空格只填一个单词。
     How do you enter a room full of strangers? Do you walk right in full of confidence? Or do you try to
slip in without being noticed? The way you go into new situations shows your level of self-confidence.
     In life, we admire those who do their tasks confidently. We prefer people who appear to know what
they're doing. But where does that confidence begin?
      Developing self-confidence starts very early. It's parents' role to get kids on the right track (轨道)
toward becoming confident people. To help that process, parents should always offer more praise than
criticism (批评). That can be done by focusing on the child's strengths. Parents should encourage their
children to try new things and take risks. When children make mistakes, their parents should still let them
know that they are loved. Children whose parents do these things will likely develop into confident adults.
But self-confidence still doesn't come easily. So what's the solution (解决办法)?
     With most things in life, practice makes perfect, and that is true of confidence skills. The more you
practice them, the easier they will become.
      Always hold your head high and look people in the eye. Answer questions clearly and confidently.
The way you walk shows others how confident you are.
     Focus on the things that you do well, and look for opportunities to use those abilities.
     Keep an item in clear view that reminds you of a recent success. It could be a good test score or a
prize from a contest. Remind yourself that one success often leads to the next.
Prepare thoroughly for every project. You'll approach the task more confidently knowing that you're
ready.
     All humans fail at times, and you will too. But don't allow mistakes to trouble you. Learning from
mistakes helps you face the same situation later without fear.
     Even with practice, you will never be perfect. But you can learn to love and accept yourself and live
your life with confidence.
