Ⅳ.短文改错
One afternoon in February, my classmate Tom and I was on the way to the cinema. Due to the ground covering with thick ice, an old woman suddenly fell down heavy. Seeing which had happened, we dialed 120 without a second thought. On such cold weather, we stayed with her until the ambulance came to scene. And then we left for the cinema. Although we were late for the film, we all thought it was worthwhile. After all，help people in need is a good way to obtain joy and happy. Now we still remember the day which we spent it together.

①考查主谓一致。主语是my classmate Tom and I，谓语动词应用复数形式，故was改为were。
②考查非谓语动词。cover与the ground是逻辑上的动宾关系，故用过去分词作后置定语。be covered with“覆盖有……”。
③考查副词。在句中修饰谓语动词fell down，应用副词作状语，故heavy改为heavily。
④考查名词性从句。Seeing后是宾语从句，从句中缺少宾语，指“所……的事情”，故用what引导宾语从句。
⑤考查介词。表示“在……天气中”，应用介词in，故On改为In。
⑥考查固定短语。come to the scene“到达现场”。
⑦考查代词。根据第一句中的“my classmate Tom and I”可知是两个人，故用代词both。
⑧考查非谓语动词。该句谓语是is, help others in need应该是主语部分，动词原形不能作主语，故help改为helping。
⑨考查名词。and连接两个并列的名词作谓语obtain的宾语，故happy应改为名词happiness。
⑩考查成分冗余。分析句子结构可知“we spend it together”是修饰the day的定语从句，故从句中不能再出现代替the day的替代词it。
