23、》被制作成至少10部不同的影片?！皁ver the past ＋時間段”通常與現(xiàn)在完成時連用，且句子主語與make之間是被動關系，所以用現(xiàn)在完成時的被動語態(tài)。 2．The lecture _______ (give), a lively question-and-answer session followed. 答案：having been given'句意：演講之后，緊跟著一個生動的問答環(huán)節(jié)。本題考查非謂語動詞。the lecture是give的邏輯主語，兩者間為被動關系，且該動作發(fā)生在謂語動詞followed之前，故應使用現(xiàn)在分詞完成式的被動形式，the lecture havi

26、undreds of jobs ____________ (lose) if the factory closes. 答案：will be lost　jobs與lose是被動關系，且條件狀語從句用一般現(xiàn)在時，主句用將來時。句意：如果這家工廠關閉，人們將失去幾百份工作。 7．____________ roses ____________ (smell) sweet? 答案：Do; smell　smell/taste/look/sound/feel是系動詞，無被動，無進行時。句意：玫瑰花聞起來很香嗎？ 8．Our teacher keeps telling us that the fut

27、ure ____________ (belong) to the well-educated. 答案：belongs　考查belong的用法。句意：我們的老師一直告誡我們說未來屬于受過良好教育的人。belong to “屬于”，此詞組在使用時要注意，不能用進行時態(tài)，也不能用被動語態(tài)。 9． There are still many problems ________ (solve) before we are ready for a long stay on the Moon. 答案：to be solved'句意：在我們準備好在月球上長久停留之前，仍然還有許多問題有待解決。本題考查非謂
