[我用双手-成就你的梦想]

你要告诉计算机，你什么时候将前一个字符串读完了，它什么时候才能去读第二个字符串

[一根烂笔头]

没有明白你的问题，你再具体点陈述下什么症状

[赵4老师]

比如 scanf("%s",pNewDic->english_word); 改为 scanf("%29s",pNewDic->english_word);

[li4c]

l楼主能说清楚点吗？不知道是什么意思

[生风虎]

赵四老师这个办法可以，我已经修改了读入文件部分：
fprintf(fp, "%s %s %s %s\n",p->english_word, p->character_word, p->soundmark_word, p->chinese_word);
fprintf(fp,"%s\n",p->english_phrase);
fprintf(fp,"%s\n",p->example_sentence);文件中基本信息在一行，凡是带空格的字符串单独一行
