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. 

Cô cảm ơn em về dòng tâm tư em gửi lên olm em nhé!

Bạn viết hay quá, chúc bạn học tốt.

I strongly agree with the idea :" wearing uniform is necessary for all students when they are at school "

Firstly , wearing uniform encourages students to be proud of being students of their school because they are wearing uniform with labels bearing their school's name. Secondly , wearing uniform can save money and time . Each morning or each day , students don't need to decide what to wear , they simply get dressed in their uniform. Furthermore , wearing uniform helps us feel equal in many ways , whether they are rich or poor . In addition, everyone wearing the same uniform allows students to be easily identified. If everyone was wearing different clothes , nobody would know where a students was from. And when you wearing uniform you look not scruffy . In conclusion wearing uniform is necessary for all students when they are at school.
