關(guān)閉窗口 七、考查非謂語動詞用作賓語補足語
原則上，所有的非謂語動詞形式均可用作賓語補足語，其區(qū)別是：不定式表未來，現(xiàn)在分詞表進行，過去分詞表完成和被動。如：
1. I couldn’t do my homework with all that noise_________. (北京卷)
A. going on B. goes on C. went on D. to go on
分析：答案選A。作with的賓語的補足語要用非謂語動詞，排除選項B和C；與謂語動作同時發(fā)生用現(xiàn)在分詞作賓語補足語，排除表示將來的不定式選項D。
2. You should understand the traffic rule by now. You’ve had it _________often enough (天津卷)
A. explaining B. to explain C. explain D. explained
分析：答案選D。賓語it與explain是被動關(guān)系，用過去分詞作賓補，have sth done意為“請人做某事”。
八、考查非謂語動詞的邏輯主語問題
按照英語習(xí)慣，非謂語動詞的邏輯主語應(yīng)與句子一致，否則就應(yīng)調(diào)整句子結(jié)構(gòu)。如：
While watching television, _________. (全國卷III)
A. the door bell rang B. the doorbell rings
C. we heard the doorbell ring D. we heard the doorbell rings
分析：答案選C。因為watching的邏輯主語一定是we，排除選項A和B；又因在hear后作賓語補足語的是省略了to的不定式，所以選項D中的rings是錯誤的。
九、考查非謂語動詞用作主語的問題
原則上說，動詞用作主語，只能是不定式或動名詞，不能是分詞形式。這類考題命題還往往用動詞原形作為干擾項進行考查，同學(xué)們做題需引起注意。如：
It’s necessary to be prepared for a job interview; _________the answers ready will be of great help. (北京卷)
A. To have had B. Having had C. Have D. Having
分析：答案選D。動名詞短語用作主語。
十、考查“(be +) 過去分詞+介詞”結(jié)構(gòu)
有一類“be+過去分詞+介詞”結(jié)構(gòu)，如be interested in, be worried about, be lost in, be dressed in 等，也往往是命題的熱點。如：
1. _________ in the mountains for a week, the two students were finally saved by the local police. (江蘇卷)
A. Having lost B. Lost C. Being lost D. Losing
分析：答案選 B。因表示“迷路于”是lose oneself in，題中沒有oneself, 所以the two students與lose是被動關(guān)系，應(yīng)該用過去分詞作狀語。
2. _________ in a white uniform, he looks more like a cook than a doctor. (湖南卷)
A. Dressed B. To dress C. Dressing D. Having dressed
分析：答案選 A。由dress的賓語一定是人或oneself可知，dress與he是動賓關(guān)系，即he與dress是被動關(guān)系，要用過去分詞作狀語，Dressed in …=As he is dressed in …
