目的状语从句是一种从属从句，用来表达主句中的动作或状态的目的或意图。它通常由“so that”、“in order that”、等引导，放在主句之后。常可以转化成不定式 in order to, to do, for the purpose of，构成简单句。

以下是一些例句：

• I’m studying hard so that I can pass the exam.
  （我正在努力学习，以便能够通过考试。）
• She bought a new dress in order that she could look nice at the party. = She bought a new dress in order to look nice in the party.
  （她买了一条新裙子，以便在聚会上看起来漂亮。）
• We’re saving money for the purpose of buying a new car.
  （我们正在存钱，为了购买一辆新车。）

在目的状语从句中，动词通常使用“can”或“could”，表示能够或可能实现目的。需要注意的是，目的状语从句中的主语通常与主句的主语一致。

目的状语从句有助于表达主语的意图或目的，使语言更加清晰明了。例如，如果没有目的状语从句，上述例句可能会变成：

• I’m studying hard.（我正在努力学习。）
• She bought a new dress.（她买了一条新裙子。）
• We’re saving money.（我们正在存钱。）

这些句子缺少了目的状语从句，使得读者无法准确理解主语的目的或意图。因此，目的状语从句在英语中是非常重要的一种语法结构。

结果状语从句是用来表示某个动作或状态所产生的结果或后果，通常由“so that”、“such that”、“that”等引导。这种从句可以出现在主句之前或之后，起到进一步说明主句内容的作用。

基本用法

表示目的和结果：
例如：I studied hard so that I could pass the exam.（我努力学习，以便能够通过考试。）
The teacher explained the grammar rules again so that everyone would understand.（老师再次解释了语法规则，以便每个人都能理解。）
He worked so hard that he finished the project ahead of schedule.（他工作得非常努力，以至于提前完成了项目。）
She spoke loudly so that everyone could hear her.（她大声说话，以便每个人都能听到她。）

表示因果关系：
例如：He was so tired that he fell asleep immediately.（他太累了，以至于立刻就睡着了。）
The weather was so bad that we had to cancel the picnic.（天气太糟糕了，我们不得不取消野餐。）

表示程度：
例如：The music was so loud that I couldn’t hear myself think.（音乐太响了，我都听不清自己的思考声
音。）
She was so happy that she couldn’t stop smiling.（她太开心了，无法停止微笑。）

注意事项

1、确定主从句的逻辑关系
结果状语从句表达的是主句中某个动作或状态所导致的结果，因此需要明确主句和从句之间的逻辑关系。例如：She studied hard, so she passed the exam.（她努力学习，所以她通过了考试。）
I woke up late, so I missed the bus.（我起床晚了，所以我错过了公交车。）

2、使用适当的引导词
结果状语从句通常由 so/such…that, so that, such that, that 等引导词引导，需要根据句子的语境和需要选择适当的引导词。例如：
She was so tired that she fell asleep on the couch.（她太累了，结果在沙发上睡着了。）
He is saving money so that he can buy a new car.（他在存钱，以便买一辆新车。）
It was such a small room that it made me feel uncomfortable.（这个房间很小，让我感到不舒服。）

3、结果状语从句中通常要使用倒装语序，即将助动词或情态动词提到主语前面，或将主语和谓语动词的位置交换。例如：
So tired was she that she fell asleep on the couch.（她太累了，结果在沙发上睡着了。）
So happy were they that they jumped for joy.（他们太高兴了，结果跳起来欢呼。）

4、注意时态和语态
结果状语从句的时态和语态需要与主句保持一致。例如：
He has been studying hard, so he is getting better grades.（他一直在努力学习，所以成绩越来越好。）
The project was completed on time, so it was highly praised.（项目按时完成，因此受到了高度赞扬。）

5、避免重复使用 so/such
如果主句中已经使用了 so/such，为避免重复，可以使用 that 引导结果状语从句。例如：
She was so tired that she fell asleep on the couch.（她太累了，结果在沙发上睡着了。）
It was such a small room that it made me feel uncomfortable.（这个房间很小，让我感到不舒服。）
The film was so boring that I fell asleep.（这部电影太无聊了，结果我睡着了。）
