Chào các bạn, Kienthuctienganh hôm nay xin phép tiếp tục với một chủ đề mới cũng rất thường gặp trong tiếng Anh phổ thông cũng như giao tiếp. Đó chính là cách sử dụng các liên từ So, Therefore, But, However. Hi vọng qua bài viết này, các bạn sẽ không bị nhầm lẫn nữa nhé.
I. Phân biệt So và Therefore
1. So
Clause1, so + clause2
Ví dụ:
- I am sick now, so I can’t do my homework. (Bây giờ tôi cảm thấy mệt, vì vậy tôi không thể làm bài tập.)
Lưu ý:
Ta vẫn có thể dùng câu mệnh lệnh bắt đầu bằng động từ nguyên mẫu không có “to” sau liên từ “so” chỉ kết quả.
Ví dụ:
- I’ve run out of milk so please give me more. (Tôi uống hết sữa rồi, vậy làm ơn cho tôi thêm chút nữa.)
2. Therefore
Clause1; therefore, clause2
Ví dụ:
I was so angry with his behavior; therefore, I decided to leave without saying anything. (Tôi đã quá tức giận về thái độ của anh ta, vì thế tôi đã quyết định bỏ đi mà không nói tiếng nào.)
3. Giống và khác nhau
Giống nhau: về nghĩa thì cả 2 từ này đều mang nghĩa là “vì thế, vì vậy”.
Khác nhau:
So | Therefore |
|---|---|
- Không đứng đầu câu mà chỉ đứng giữa câu, trước “so” có dấu phẩy (,). | - Nếu đứng đầu câu thì sau therefore có dấu phẩy. |
- So thường được dùng trong văn nói, không trang trọng. | - Therefore thường được dùng trong văn viết, trang trọng hơn. |
II. Phân biệt But và However
1. But
Clause1, but + clause2
Ví dụ:
This hotel is not large, but it’s so modern. (Khách sạn này thì không quá lớn nhưng nó khá là hiện đại.)
2. However
Clause1; However, clause2
Ví dụ:
I am good at math; however, my best friend, Minh is better than me. (Tôi giỏi toán; tuy nhiên, người bạn thân của tôi, Minh còn giỏi hơn tôi.)
3. Giống và khác nhau
Giống nhau: về nghĩa thì cả 2 từ này đều mang nghĩa là “nhưng, tuy nhiên”.
Khác nhau:
But | However |
|---|---|
- Không đứng đầu câu mà chỉ đứng giữa câu, trước “but” có dấu phẩy (,). | - Nếu đứng đầu câu thì sau however có dấu phẩy. |
- But thường được dùng trong văn nói, không trang trọng. | - However thường được dùng trong văn viết, trang trọng hơn. |
