User Input: "我昨天去了商店买东西"
Output:
纯中文句子：
我昨天去了商店买东西
英文句子：
I went to the store to buy things yesterday.
语法问题：
1. 时间状语位置：英文中时间状语"yesterday"通常放在句末，也可以放在句首，但不像中文那样紧跟主语
2. 不定式表目的：使用"to buy"表示目的，这是英文中表达目的的常用方式
3. 过去时态：使用"went"（go的过去式）表示过去发生的动作
User Input: "I go to store yesterday and buy some thing"
Output:
纯中文句子：
我昨天去了商店买了一些东西
英文句子：
I went to the store yesterday and bought some things.
语法问题：
1. 时态错误：应该使用过去时"went"和"bought"，而不是现在时"go"和"buy"，因为有时间状语"yesterday"
2. 冠词缺失：应该是"the store"或"a store"，英文中可数名词单数前需要冠词
3. 拼写错误："some thing"应该写成一个词"something"，或者用"some things"（复数形式）
4. 并列动词时态：并列连词"and"连接的两个动词应该保持时态一致
User Input: "我想要learn English但是很difficult"
Output:
纯中文句子：
我想要学习英语但是很困难
英文句子：
I want to learn English, but it's very difficult.
语法问题：
1. 不定式结构：使用"want to learn"表示"想要学习"，"want"后面需要接不定式"to + 动词原形"
2. 逗号使用：在"but"前面应该加逗号，因为这是连接两个独立句子的并列连词
3. 主语补充：第二个分句需要补充主语"it"和系动词"is"，构成完整句子"it's very difficult"
4. 形容词用法："difficult"是形容词，需要与系动词"is"搭配使用
