Giải đề luyện cuối học kì I Tiếng Anh 8 — 30 câu tuyển chọn

Mount Everest is the highest mountain above sea level. Climbing it is demanding because the air is thin and the weather can be severe. Many climbers carry oxygen bottles. Some discarded bottles and damaged tents have been left on the mountain, creating a serious rubbish problem. This passage describes empty oxygen bottles left on the ground. When strong winds rip tents, some people leave them behind because they lack the energy to carry everything down. Cleanup groups have collected some rubbish. Climbers should plan to bring their own waste down rather than rely on these groups. The account does not provide a current count of climbers or the total weight of waste.
