關(guān)閉窗口 有關(guān)非謂語動(dòng)詞的重要考點(diǎn)
一、考查不定式、現(xiàn)在分詞與過去分詞的基本區(qū)別
從時(shí)間關(guān)系上看，不定式表未來，現(xiàn)在分詞表進(jìn)行，過去分詞表完成，同時(shí)注意不定式和現(xiàn)在分詞的完成式也表完成(尤其是表示有明顯的先后關(guān)系的完成)；從主動(dòng)與被動(dòng)來看，不定式和現(xiàn)在分詞表主動(dòng)，過去分詞表被動(dòng)，同時(shí)注意不定式和現(xiàn)在分詞的被動(dòng)式也表被動(dòng)(不定式的被動(dòng)式在表被動(dòng)的同時(shí)還兼表未來，現(xiàn)在分詞的被動(dòng)式表被動(dòng)的同時(shí)還兼表進(jìn)行)。如：
1. I send you 100 dollars today, the rest _________ in a year. (湖南卷)
A. follows B. followed C. to follow D. being followed
【分析】答案選 C。動(dòng)詞不定式表示未來的動(dòng)作。
2. _________from other continents for millions of years, Australia has many plants and animals not found in any other country in the world. (湖北卷)
A. Being separated B. Having separated C. Having been separated D. To be separated
【分析】答案選 C。因?yàn)?/FONT>Australia與separate是被動(dòng)關(guān)系，且separate發(fā)生在謂語動(dòng)詞has之前，所以用現(xiàn)在分詞的完成被動(dòng)式作原因狀語。
二、考查非謂語動(dòng)詞的主動(dòng)式與被動(dòng)式
結(jié)合句子意思，考察非謂語動(dòng)詞與相應(yīng)邏輯主語的關(guān)系，若為主動(dòng)關(guān)系，用主動(dòng)式；若為被動(dòng)關(guān)系，用被動(dòng)式。此時(shí)要特別注意，過去分詞沒有相應(yīng)的被動(dòng)式，因?yàn)樗旧砜梢员硎颈粍?dòng)。如：
1. The repairs cost a lot, but it’s money well_________. (湖北卷)
A. to spend B. spent C. being spent D. spending
【分析】答案選B。因money與spend是被動(dòng)關(guān)系，所以用過去分詞。
2. The prize of the game show is＄30000 and an all expenses _________ vacation to China. (北京卷)
A. paying B. paid C. to be paid D. being paid
【分析】答案選B。因all expenses與pay是被動(dòng)關(guān)系，故用過去分詞。注意句中的an 不是修飾 expenses，而是修飾vacation。
3. When _________help, one often says, “Thank you.” Or “It’s kind of you.” (福建卷)
A. offering B. to offer C. to be offered D. offered
【分析】答案選 D。因一個(gè)人說“謝謝”，應(yīng)當(dāng)是他被提供了幫助，所以要用過去分詞，When offered help… =When he is offered help…
三、考查非謂語動(dòng)詞完成式的用法
非謂語動(dòng)詞(不定式、動(dòng)名詞和現(xiàn)在分詞)的完成式主要表示發(fā)生在謂語動(dòng)作之前的動(dòng)作。做題時(shí)要注意根據(jù)題干所提供的語境來推斷這種先后關(guān)系。如：
1. The storm left, _________a lot of damage to this area. (全國卷I)
A. caused B. to have caused C. to cause D. having caused
【分析】答案選D。因The storm與cause是主動(dòng)關(guān)系，排除選項(xiàng)A；不定式作狀語，前面通常不用逗號(hào)，排除B和C；因暴風(fēng)雨給這個(gè)地區(qū)“造成損失”是在“結(jié)束”之前，所以用完成式。
2. More and more people are signing up for Yoga classes nowadays, _________ advantage of the health and relaxation benefits. (上海卷)
A. taking B. taken C. having taken D. having been taken
【分析】答案選 A。因people與take advantage of是主動(dòng)關(guān)系，排除選項(xiàng)B和D；take不會(huì)發(fā)生在謂語are signing up之前，不用完成式，排除C。
