阅读下文,回答相关问题。

                                                                                                        我 能 行
         ①一个人的成功,一定要有“我能行”的成功意识和自信心。
         ②科学家对创造型人才的调查和研究表明,创造型人才的一个重要特征是不怕失败,不迷信别人,不迷信权威,他们有一种强烈的自信心。美国的心理学家曾进行过一项历时几十年的研究,他们对具有较高智力的学生进行长期的跟踪调查,发现智力、成绩相似的学生,几十年后的成就相差很大,究其原因,不是因为智力的差异,而是人格特征方面的不同
        ③“我能行”,并不是一种狂妄。心理学研究表明,绝大多数人都能行。人们的智力相差是不大的。据心理学家测试,智力超常者和智力低下者都占很少的一部分,约占95%的人是中等智力。因此,大多数人的确有理由说“我能行”。
        ④“我能行”,还因为每个人都拥有极大的潜力。脑科学研究表明,一般人的大脑,只开发了很小的一部分。正如一棵平常的西红柿只能结20来个果实,但是日本筑波博览会上的一棵西红柿却结了13000个果实。我们每个人都是一棵这样的潜在的西红柿。尽管我们平常都只结出了20来个果实,但是,从潜在的能力上,我们每个人是能结出13000个甚至更多的“西红柿”的。因此,每个人都可以自豪地说“我能行”。
        ⑤但是,                                   。让他们学习一种新知识,负责某一方面的工作,他们总是说:“我不行,我不行。”在这种心态下,就不可能主动地学习,就不会勇敢地往自己的肩上增添压力。遇到一点困难和失败就会心灰意冷,这种失败意识阻碍着自己的努力,减少了成功的可能性。因此“我不行”是一种有害的意识。
        ⑥我们历来称颂谦谦君子,认为说“我能行”的人是狂妄之徒,这是不利于充分发挥人的潜力的,这种偏见扼杀了人们的创新精神。因此,我们应该创造一个良好的、有利于人的潜能充分发挥的社会氛围。
        ⑦只有坚信“我能行”才能走向成功。

    With busy lives, it can be hard to find time to volunteer. However, the benefits of volunteering are great to you, your family, and your community(社区).

    One of the better-known benefits of volunteering is the effect on the community. Volunteering allows you to connect with your community and make it a better place. Volunteering also strengthens your ties to the community and broadens your support network, exposing(使暴露) you to people with common interests, neighborhood resources, and fun and satisfactory activities.

    While some people are naturally outgoing, others are shy and have a hard time meeting new people. Volunteering gives you the opportunity to practice and develop your social skills, since you are meeting regularly with a group of people with common interests. Once you have the desire, it's easier to make more friends and contacts.

    Volunteering provides many benefits for both mental and physical health. You're doing good to others and the community, which makes you experience the pleasure of success. Your role as a volunteer can also give you a sense of pride and identity.

    Reducing the risk of depression(沮丧) is another important benefit of volunteering. A key risk factor for depression is social isolation. Volunteering keeps you in regular contact with others and helps you develop a solid support system, which in turn protects you against stress and depression when you're going through challenging times. Volunteering is good for your health whether you are young or old, but it's especially good in older adults.

    Volunteering offers you the chance to try out a new career without making a long-term commitment. It is also a great way to gain experience in a new field. Volunteering work can expose you to professional organizations or internship(实习)that could be of benefit to your career. That volunteer work is unpaid doesn't mean the skills you learn are basic. Many volunteering opportunities provide training. In addition, volunteering can also help you build upon skills you already have and use them to benefit the greater community.

    Volunteering is a fun and easy way to explore your interests and passions. Volunteer opportunities that match both your goals and your interest are most likely to be fun and satisfying for you. Doing volunteer work you find meaningful and interesting can be a relaxing escape from your day-to-day routines of work, school, and family commitments. Volunteering also provides you with renewed creativity, motivation, and vision that can be carried over into your personal and professional life.
