Đáp án A

Kiến thức: Mạo từ 

Giải thích: 

Về 1 đối tượng dạng số ít đếm được lần đầu nhắc đến, ta sử dụng mạo từ “a”/ “an” ( “an” với các danh từ có âm tiết đầu là “u,e,o,a,i”; “a” với các trường hợp còn lại)

Về 1 đối tượng mang nghĩa khái quát, chung chung, đã xác định, ta dùng mạo từ 

the” ( on the pavement : trên vỉa hè) 

Tạm dịch: Khi tôi đang đi dạo phố, tôi nhìn thấy 1 tờ 10 đô trên vỉa hè.

Đáp án A

Dùng a hoặc an trước một danh từ số ít đếm được. Chúng được dùng trong câu có tính khái quát hoặc đề cập đến một chủ thể chưa được đề cập từ trước. An dùng với các danh từ bắt đầu bằng nguyên âm, a dùng với các danh từ bắt đầu bằng phụ âm.

Dùng “the“ trước một danh từ đã được xác định cụ thể về mặt tính chất, đặc điểm, vị trí hoặc đã được đề cập đến trước đó, hoặc những khái niệm phổ thông, ai cũng biết.
