2. 以"只抱怨不行動,毫無意義"為題寫壹篇英語作文"Almost everyone knows the famous Chinese saying: A young idler, an old beggar. Throughout history, we have seen many cases in which this saying has again and again proved to be true.
It goes without saying that the youth is the best time of life, during which one's mental and physical states are at their peaks. It takes relatively less time and pains to learn or accept new things in a world full of changes and rapid developments. In addition, one is less likely to be under great pressure from career, family and health problems when young. Therefore, a fresh mind plus enormous energy will ensure success in different aspects of life.
Of course, we all know: no pains, no gains. If we don't make every effort to make good use of the advantages youth brings us, it is impossible to achieve any goals. As students, we should now try our best to learn all the subjects well so that we can be well prepared for the challenges that we will face in the future.
3. 關於不要抱怨人生的英語名言運用智慧就能不抱怨，壹個人的成功，意誌力和決心的力量是不容忽視的，它是成敗的重要關鍵。
——遠雄企業集團董事長 趙騰雄
抱怨是最消耗能量的無益舉動。有時候，我們不僅會針對人、也會針對不同的生活情境表示不滿；如果找不到人傾聽我們的抱怨，我們還會在腦海裏抱怨給自己聽。本書作者提出的神奇“不抱怨”運動，來得恰是時候，它正是我們現代人最需要的。我們可以這樣看：天下只有三種事：我的事，他的事，老天的事。抱怨自己的人，應該試著學習接納自己；抱怨他人的人，應該試著把抱怨轉成請求；抱怨老天的人，請試著用祈禱的方式來訴求妳的願望。這樣壹來，妳的生活會有想象不到的大轉變，妳的人生也會更加地美好、圓滿。
——《遇見未知的自己》作者 張德芬
不要讓抱怨操控妳、支配妳。如果妳不滿某種狀況，就應該開始描繪挑戰不復存在、落差已經填補、問題也獲得解決的光明願景，以促使人們做出積極、正面的改變。
