The first rule stepping up your luck is to look for variety. More variety will result in a richer life with more opportunities. The more varied life is, the more likely that unexpected combinations of events will occur, giving us the chance to improve our situation. Being able to change is the best way to survive in changing, unpredictable times.When we are searching for something, like a pair of lost eyeglasses, it isn’t a good idea to always follow the same pattern of search. Searching for happiness is like that as well. Be flexible. Learn from your mistakes. Try lots of different possibilities.Variety is necessary for happiness. No matter how rich our lives may seem, if they consist only of expected events and repetition, boredom steps in. We find pleasure in the unexpected and the surprising. Saying yes to uncertainty adds pleasure to life and contributes to our luck. Sometimes it seems easier, however, to use our strength to build walls to try to protect ourselves from uncertainty. We buy life insurance, household insurance, car insurance. We work hard and put money aside. But all this planning can’t guarantee safety. We need to find the courage to welcome uncertainty.Each of us should find one action that will increase variety: subscribe to a new magazine, take a different route to work, sign up for a night-school course. Then focus on its positive results. This positive reinforcement, together with the pleasure of sensing the power in doing what we want to, should give us the courage for the next act.Accepting ourselves exactly as we are at this present moment provides the courage to move forward. Believing that all our choices in the past were the best we could have made at the time frees us from regret and reinforces our belief that we are as good as we can be at this moment. The best preparation for the future is self-acceptance in the present. Self-acceptance and trust in people are the foundations of confidence and courage.Self-acceptance, courage and action don’t guarantee good luck, but they do guarantee a richer and fuller life. The best title of the text would be()

全面实施素质教育的要求下,怎样评价学生的优、良、中、差呢为此,我制订了这样的标准:一是在大纲规定的基础科60分以上,并能发现自己的特长且有所发展的,视为及格;二是基础科及格或良好,特长科明显超过同年级学生的,视为良好;三是基础科良好,特长科大大超过同年级学生或有所发明创造的,视为优秀;四是仅基础科及格或仅特长科有所发展的,均视为不及格;五是仅基础科良好,或特长科单方独进的,视为畸形发展,作降格评价。这一评价标准的实施,使绝大部分差生都抬起头来走路,找到了自己成才的优势与途径,也使文化课考试分数好的学生不再自我感觉良好,从而找到了良性互补、和谐发展的新路子。通过一个学期的实践,学生的学习积极性明显高涨,各科学习成绩有了大幅度的提高,各科总分由原来年级的倒数第二,上升到年级的第二名。 问题:请你针对案例中制订的评价标准,谈谈自己的看法。
