| 任务型阅读。 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。 There are two basic ways to see growth: one as a product, the other as a process. People have generally viewed personal growth as an external (外在的) result or a product that can easily be identified and measured.The worker who gets a rise, the student whose grades improve, the foreigner who learns a new language-all these examples of people who have measurable results to show for their efforts. By contrast (对照), the process of personal growth is much more difficult to determine, since it is a journey and not the specific signposts or landmarks along the way.The process is not the road itself, but the attitudes, feelings people have, and their caution or courage, as they meet with new experiences and unexpected difficulties.In this process, the journey never really ends；there are always new ways to experience the world, new ideas to try, new challenges to accept. In order to grow, to travel new roads, people need to have a willingness to take risks, to face the unknown, and to accept the possibility that they may "fail" at first.How we see ourselves as we try a new way of being is necessary for our ability to grow.Do we see ourselves as quick and curious? If so, we tend to take more chances and be more open to unfamiliar experiences.Do we think we're shy and indecisive? Then our sense of fear can cause us to hesitate, to move slowly, and we think we are slow to adapt (适应) change or that we're not smart enough to deal with a new challenge.Then we are likely to take a more passive role or not try at all. These feelings of insecurity (不安全) and selfdoubt are both unavoidable and necessary if we are to change and grow.If we protect ourselves too much, then we stop growing.We become trapped inside a shell of our own making.
