It /

10、 This / That + the first(second , third ) time + that-clause這個(gè)句型表示截止到說話時(shí)為止的某人的一種經(jīng)歷，關(guān)鍵是注意time前有序數(shù)詞，主句是 is 時(shí) ，從句要用現(xiàn)在完成時(shí)；如果主句用一般過去時(shí)was ，則從句須相應(yīng)地用過去完成時(shí)。例如：This is the first time (that) these Europeans _the Great Wall .It was the fifth time (that) I _a friendly visit to Africa . had paidhave visited 結(jié)構(gòu)：It
