The air was filled with the sound of machinery and the rhythmic tap of hammers, transforming ruins into structures. People from all walks of life came together, their faces lined with determination. Some cleared ruins, and some drafted architectural plans, while others contributed through supporting activities, such as preparing meals for the workers. These activities, though seemingly simple, made up the joint efforts of the recovering community. The process of rebuilding is more than the physical restoration of homes and facilities. It's a meaningful reestablishment of community spirit, shared values, and collective memories. As new structures rose, so did the spirit of those involved. The story of reconstruction is not merely a narrative of overcoming hardships, but also a beacon of hope, showing the power of community and human persistence in face of adversity. 主题表达升格训练 课时作业评价 Ⅰ.根据要求完成下列句子 1．(同义替换)Her words affected (＝_________________) him, changing his perspective forever. 2．(完成句子)He talks about the fictional characters _________ _______________(好像他们是真实的人)． 3．(完成句子)The city _________________(这座城市正在睡梦中就在这时) the earthquake struck. had an effect on as if they were real people was sleeping when 4．(完成句子)Our country ____________________(有丰富的) natural resources. 5．(完成句子)She __________________(不遗余力地) make her dream come true. has a good supply of spared no effort to 6．(一句多译)当我走过老街区时，我突然意识到这些年来发生了很多变化。 ①As I walked through the old neighborhood, _______________much had changed over the years. ②As I walked through the old neighborhood, _____________much had changed over the years. ③As I walked through the old neighborhood, ___________________ much had changed over the years. it struck me that it hit me that it occurred to me that 7．(句型转换)The mountain was so steep that no one could climb without proper equipment.

One of the simplest ways to avoid food waste is to buy proper amount of food. Besides, we are supposed to think twice before throwing food away, urging ourselves to carry out the Empty Plate Campaign. Lastly，storing food correctly also contributes to less food loss. As high school students, it's our responsibility to say NO to food waste, which will benefit the world, now and in the future. $$
