　　(2017·龙岩市质量检测)The King's School, Canterbury is an independent, coeducational secondary school. There are currently 791 pupils on the school roll (名单). The School has a long and distinguished history, and it is also one of the oldest charities in the country, providing scholarships to pupils and organizing a Charity of the Term.

　　The curriculum (课程) at King's is based on strong academic roots. It emphasizes and relies upon what is best in traditional independent school education: scholarly excellence supported by a caring and tutorial system, and a wide­ranging co­curricular programme. However, it is continually adapting and reacting to the changing demands of modern education: new subjects are added, new teaching techniques adopted, and there is an increasing awareness of the need to provide programmes of study that match individual needs and skills.
