I felt very ashamed

作者投入两年积蓄参加英语培训,希望通过提高英语水平找到更好的工作机会。在实际学习过程中遇到了困难,进步缓慢,感到沮丧。

About four months ago, I spent my savings of two years on the English Training.

The initial purpose of it was to find a shortcut to success.

Because in my practical life, I found it's so difficult to improve the professional skills to a high level. And even if I reach that level, the benefits are just so-so.

But if I can speak fluent English, it is very easy to find a very good job.

 

Actually in my heart of hearts I feel inferior about my college. I attained a very lousy mark in the university Entrance Examination, so I couldn't get into the good university.

Thankfully, in my past work I did pretty good and was approved by many people. My self-confidence was gradually returning, but I still not really found the things which can make my inside stronger.

 

Then I thought about the English, the fluent spoken English. With my steady improvement professional skills, I can tell others about my history more confidently, I have the ability to own a good future.

 

In the past, I hesitated whether I should upgrade my diploma to Undergraduate or re-enter the university for postgraduate. But inwardly I don’t want that. They will waste so much time but could not get anything of value. Maybe you think I can get the diploma. Just for this? Is this really what I want in my life? No! Absolutely not! I will not yield.

 

I believed that I found the right way to success, but I’m ashamed for the effect of English learning.

I have already learned about four months, but little progress. Compare with the others in the conversation course, I still have a long way to go. Many of them are high school students, or university students. When they chat with the foreign teachers, they’re so fluent and comfortable.

They always talk about the study abroad, the foreign culture, the fashion and so on. They don’t worry about the money because they are rich or their parents are. It seems that we are not in the same stratum.

 

I actually planned some method for the quick to learn, for example, prepare all the sentences I may use in the training centre, classify the words in my daily life by some different topics, or imagine a conversation about something interesting.

 

But I just planned them, didn’t do. So each time when I thought of this, compared with others, I felt very ashamed.

 

Time flies. But I still have time to build the beautiful future. Do it properly or don't do it at all.

你提供的 `dict.txt` 文件内容是典型的 **英译英词典格式**,每一行由一个单词(或词组)和一个对应的英文解释组成,用空白(空格或制表符)分隔。 --- ## ✅ SQLite 在这个项目中的作用(结合你提供的 dict.txt 内容) ### 1. **持久化存储字典数据** 目前你使用 `dict.txt` 文件来存储单词和解释,这是一种 **静态文本文件存储方式**。如果你希望实现: - 单词数据的快速查询 - 动态更新(添加、删除、修改单词) - 多用户共享访问 - 避免频繁读取文本文件 那么就可以使用 **SQLite** 来替代文本文件,将 `dict.txt` 中的内容导入数据库中。 --- ## ✅ 如何将你的 dict.txt 导入 SQLite? ### 1. 创建 `dictionary` 表结构 ```sql CREATE TABLE IF NOT EXISTS dictionary ( word TEXT PRIMARY KEY NOT NULL, meaning TEXT NOT NULL ); ``` ### 2. 编写 C 程序将 `dict.txt` 内容导入数据库 ```c #include <stdio.h> #include <stdlib.h> #include <string.h> #include <sqlite3.h> #define BUFFER_SIZE 1024 int main() { sqlite3 *db; int rc = sqlite3_open("dictionary.db", &db); if (rc != SQLITE_OK) { fprintf(stderr, "无法打开数据库: %s\n", sqlite3_errmsg(db)); return 1; } // 创建字典表 const char *create_sql = "CREATE TABLE IF NOT EXISTS dictionary (" "word TEXT PRIMARY KEY NOT NULL, " "meaning TEXT NOT NULL);"; char *err_msg = 0; if (sqlite3_exec(db, create_sql, 0, 0, &err_msg) != SQLITE_OK) { fprintf(stderr, "创建表失败: %s\n", err_msg); sqlite3_free(err_msg); } FILE *fp = fopen("dict.txt", "r"); if (!fp) { perror("无法打开 dict.txt"); sqlite3_close(db); return 1; } char line[BUFFER_SIZE]; while (fgets(line, sizeof(line), fp)) { char word[256] = {0}; char meaning[1024] = {0}; // 使用 sscanf 提取单词和解释 if (sscanf(line, "%s %[^\n]", word, meaning) == 2) { char sql[2048]; snprintf(sql, sizeof(sql), "INSERT OR IGNORE INTO dictionary (word, meaning) VALUES ('%q', '%q');", word, meaning); if (sqlite3_exec(db, sql, 0, 0, &err_msg) != SQLITE_OK) { fprintf(stderr, "插入失败: %s\n", err_msg); sqlite3_free(err_msg); } } } fclose(fp); sqlite3_close(db); printf("数据导入完成\n"); return 0; } ``` --- ## ✅ 使用 SQLite 查询单词 将下面的函数加入服务器代码中用于从数据库中查找单词解释: ```c const char* lookup_meaning_from_sqlite(sqlite3 *db, const char *word) { static char meaning[1024]; // 静态变量用于返回结果 char sql[1024]; snprintf(sql, sizeof(sql), "SELECT meaning FROM dictionary WHERE word = '%q';", word); sqlite3_stmt *stmt; if (sqlite3_prepare_v2(db, sql, -1, &stmt, NULL) != SQLITE_OK) { return "数据库查询失败"; } if (sqlite3_step(stmt) == SQLITE_ROW) { strncpy(meaning, (const char *)sqlite3_column_text(stmt, 0), sizeof(meaning) - 1); } else { strncpy(meaning, "未找到该单词的解释", sizeof(meaning) - 1); } sqlite3_finalize(stmt); return meaning; } ``` --- ## ✅ 总结:SQLite 的优势 | 特性 | 说明 | |------|------| | 快速查询 | 支持索引,查询效率高 | | 数据安全 | 支持事务,避免数据损坏 | | 易于维护 | 可以使用 SQLiteStudio 等工具查看、修改数据 | | 可扩展性强 | 可以添加字段如例句、词性、音标等 | ---
