【解析】随着冬季到来雨雪增多，天气变冷道路变滑，文中提醒学生们注意安全及采取有效措施。
1.are→is.考查主谓一致。此处考查主谓一致，there be句型就近一致，句中按much rain是单数决定谓语也用单数形式，故are→is.
2.too→so.考查固定句型。too… to…“太…而不能…”；so… that…“如此…以至于”；此处表示天气是如此的冷以至于许多学生感冒了，是so… that…句型，that后加句子。故too→so.
3.them→themselves.考查代词。当句中主语和宾语一致时宾语用反身代词，此处主语和宾语都指some students，故them→themselves.
4.because后加of.考查固定结构。because后加句子, because of后加短语，此处the icy roads是短语要用because of，故because后加of.
5.what→that/which.考查定语从句。句中包含定语从句，先行词是many things指物，在定语从句中作主语，用关系代词that/which，故what→that/which.
6.up→on.考查动词短语。put up建造，举起； put on穿上。此处指多穿衣服用put on，故up→on.
7.去掉to.考查祈使句。句意：记着不要在光滑的路上跑或快走。此处是祈使句动词用原形，故去掉to.
8.taking→taken.考查非谓语动词。此处是现在完成时的被动形式，结构为have been done，动词用过去分词，指措施被采取。故taking→taken.
9.step→steps.考查名词。此处step是可数名词，表示台阶用复数形式，故step→steps.
10.health→healthy.考查形容词。此处和 and前的 safe 并列作is的表语用形容词，指安全健康，故health→healthy.
