　　答案及解析：

　　6.(B) 這是一個固定結(jié)構(gòu)(或句型)。本句也可說在"Four years have passed since John left school.

　　”或“has been four years sinceJohn left schoo1.''

　　7，(C) until引導的時間狀語從句用了一般現(xiàn)在時表示將來的意思，主句因此必須用一般將來時與之呼應

　　，口語中常用將來進行時代替一般將來時表示預料即將發(fā)生或肯定發(fā)生的事，也可表示某件事已經(jīng)決定了。本

　　句完全可以用will go 因此，正確答案是(C)。

　　8.(C) by the time引導的時間狀語從句中若謂語動詞用現(xiàn)在時，則主句要用將來完成時;若謂語動詞用過

　　去時，則主句要用過去完成時，有時也可以用過去將來完成時。這樣，本道題目的正確答案是(C)。

　　9.(D) 有具體表示過去某一時間段內(nèi)業(yè)已發(fā)生的事件的時間狀語，句子應該用過去完成時。

　　10.(B) 由第一個句子中的but引導的轉(zhuǎn)折句中所用的過去時，可以判斷總統(tǒng)本要在機場接見代表團，表示

　　計劃要做某事在英語中可以用be+動詞不定式來表達，故正確答案是B)。
