23、同的影片。“over the past ＋時(shí)間段”通常與現(xiàn)在完成時(shí)連用，且句子主語與make之間是被動(dòng)關(guān)系，所以用現(xiàn)在完成時(shí)的被動(dòng)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(gè)生動(dòng)的問答環(huán)節(jié)。本題考查非謂語動(dòng)詞。the lecture是give的邏輯主語，兩者間為被動(dòng)關(guān)系，且該動(dòng)作發(fā)生在謂語動(dòng)詞followed之前，故應(yīng)使用現(xiàn)在分詞完成式的被動(dòng)形式，the lecture having been giv

25、答案：to be read　考查不定式的被動(dòng)形式。句意：大部分公路兩旁都有廣告牌，這些廣告牌是為了讓來往的司機(jī)看的。be intended to do sth.“是用來做……的”，再依據(jù)后面的“by passing drivers”可知，應(yīng)用被動(dòng)式。 5． The stones each ____________ (weigh) as much as two tons. 答案：weigh　考查主謂一致和語態(tài)。句意：這些石頭每個(gè)重達(dá)兩噸。本句的主語The stones是復(fù)數(shù)形式，故謂語動(dòng)詞用復(fù)數(shù)形式；且weigh“重量是……”，無被動(dòng)語態(tài)，故空處填weigh。 6．Hundreds of

26、jobs ____________ (lose) if the factory closes. 答案：will be lost　jobs與lose是被動(dòng)關(guān)系，且條件狀語從句用一般現(xiàn)在時(shí)，主句用將來時(shí)。句意：如果這家工廠關(guān)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(dòng)詞，無被動(dòng)，無進(jìn)行時(shí)。句意：玫瑰花聞起來很香嗎？ 8．Our teacher keeps telling us that the future _______

27、_____ (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(shí)要注意，不能用進(jìn)行時(shí)態(tài)，也不能用被動(dòng)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(zhǔn)備好在月球上長(zhǎng)久停留之前，仍然還有許多問題有待解決。本題考查非謂語動(dòng)詞作定語。根據(jù)句意

28、可知“這些問題還未解決”，to be solved既表被動(dòng)又表示將來，故答案為to be solved。 10．His puter, which cost him a sum of money several weeks ago, is out of order and wants ____________ (repair), though it looks very new. 答案：repairing/to be repaired　考查被動(dòng)語態(tài)。句意：他幾個(gè)星期前花了一大筆錢買的電腦，盡管看起來很新，但是發(fā)生了故障，需要修理。want doing sth.“需要做某事”，可用主動(dòng)形式表示被動(dòng)含義，也可用to be done結(jié)構(gòu)。
