答案：
解析：
【小题1】考查序数词。five的序数词形式是fifth。故填fifth。
【小题2】考查副词的用法。修饰动词does用副词，根据makes many mistakes可知，是粗心地。carelessly“粗心地”。故填carelessly。
【小题3】考查时态。根据yesterday可知，应该用一般过去时。buy的过去式是bought。故填bought。
【小题4】考查固定短语。further education“继续教育，进修”。故填education。
【小题5】考查形容词。harmful“有害的”，反义词是harmless。根据“这些昆虫完全无害”可知，应该用harmless。故填harmless。
