Ⅴ. 单元词汇整合——背诵下面短文(黑色字体为本单元必备词汇) Our class is comprised of thirty students from the countryside. Deep down，all of us envision ourselves attaining respectful jobs in urban cities in the near future. Dreams are rooted in our hearts. We are greatly convinced that being entirely devoted to our study can boost our confidence in tackling crises. We will combine conventional learning methods with modern ones to expand our knowledge. We'll bravely output what we have learned. Certainly，it is essential that we shouldn't yield to difficulties. The instant we can't digest what the teacher says in class，we will be overcome with sorrow. Too much homework generates much strain，but we have alternative methods to alleviate our frustration. For instance，we will buy nutritious foods in a grocery store in our leisure time，although we have a shortage of money. On the assumption that we always have such an intense interest in study，it is estimated that we can put our dreams into reality，which in turn can enable us to live a better life that we have been looking forward to. $
