Blended learning is a new educational way that combines traditional classroom instruction with online or digital learning activities. There are several benefits to blended learning, including increased flexibility and convenience for students, improved engagement and motivation, and more personalized learning experiences. Blended learning allows students to access educational resources and materials anytime and anywhere, which can help them balance their academic responsibilities with other commitments. Additionally, online components can provide students with interactive and multimedia-rich experiences that can enhance their understanding and retention of course content. By combining the best of both online and offline learning, blended learning can create a more dynamic and effective educational experience for students.

Blended learning is a way of studying a subject brings several benefits to us. Blended learning allows educators to personalize the learning experience for each student. Teachers can provide students with individualized learning plans, and digital resources can be adapted to meet the unique needs of each student. Moreover, Blended learning can increase student engagement. Digital resources, such as videos, simulations, and interactive quizzes, can be more engaging than traditional lectures, helping students to better understand and retain the material. Blended learning also provides access to a wide range of learning resources, including multimedia content, online textbooks, and interactive simulations. This can enrich the learning experience and help students to better understand complex concepts. In short, blended learning can provide a rich and engaging educational experience for students, and enable educators to more effectively support student learning and success.

Online learning offers a unique blend of convenience and self-directed study. Students can tailor their learning pace, revisiting lectures or pausing to take notes as needed. The flexibility allows them to fit studies around their work or personal life, learning anytime and anywhere with an internet connection. This empowers them to organize their own study schedule, maximizing their learning potential. However, online learning also presents challenges. Technical difficulties can disrupt the learning process, and long hours spent in front of a computer screen can lead to fatigue. Perhaps the biggest drawback is the lack of face-to-face interaction. Online discussions can't fully replicate the energy and exchange of ideas that occur in a traditional classroom setting. 

Dear Sir/Madam,

I am very glad to hear that the library is taking measures to improve its services and facilities. Therefore, I am writing this letter to offer my proposals.

As we know, libraries are essential for students and researchers. They also play a useful social role in education and entertainment for the general reader.

In my opinion, libraries should make the best of their latest publications => chỗ này mình chưa hiểu ý bạn lắm, có phải là 'thư viện nên đảm bảo có đủ những ấn phẩm mới nhất' không á :D, as well as ensure they have a full set of classical and reference works.

What is probably important in this age is access to the Internet on computers. That way, the library can expand its services for readers on a worldwide basis.

Furthermore, computers are used in major libraries to streamline cataloguing and administrative tasks. 

All reliable evidence lend support view along with social development libraries take necessary measures keep up times (chỗ này mình cũng không hiểu :D)

Yours sincerely

Nhận xét chung nha: Bạn có ý nhưng mà còn thiếu logic và kết nối giữa các ý, recommend bổ sung thêm từ nối (furthermore, besides...) + mấy phần bạn sử dụng V(2,ed) mình chưa hiểu lắm là sao lại dùng ở quá khứ nhỉ. Theo mình thấy thì bạn đang offer proposals cho thư viện để nâng cấp dịch vụ và cơ sở vật chất, như vậy thì bạn có thể dùng ở thì hiện tại, hoặc thêm I think, should + V... Bạn có ý nhưng chưa triển khai ý ra. Ví dụ, ở ý này 'In my opinion, libraries should its make the best of their latest publications as well as make sure it has a full set of classical and reference works.' bạn có thể bổ sung thêm một câu về lợi ích của việc này là gì chẳng hạn.
