試題分析;考查固定句型中的時態(tài)。固定句型：It/This is/was the 序數(shù)詞 time that sb 現(xiàn)在完成時/過去完成時；如果前面是is，后面使用現(xiàn)在完成時，如果前面是was, 后面使用過去完成時。句意：我過去常常宿營。所以這不是我第一次在帳篷里睡覺。根據(jù)前面的is，說明后面使用現(xiàn)在完成時。故A正確。
點(diǎn)評：固定句型：It/This is/was the 序數(shù)詞 time that sb 現(xiàn)在完成時/過去完成時；如果前面是is，后面使用現(xiàn)在完成時，如果前面是was, 后面使用過去完成時。
