11.leonardo da vinci(1452～1519)________birds kept in cages in order to have the pleasure of setting them free.
a.is said to be buying
b.is said to have bought
c.had said to buy
d.has said to have bought
解析：選b。本題考查動詞不定式及時態的應用。因為say與主語(人)是動賓關系，所以應用被動語態；再由括號中的時間標志可知應用現在完成時。故選b。
2【教材原句】 having collected and evaluated the information，i help other scientists to predict where lava from the volcano will flow next and how fast.(p34)
收集和評估了這些信息之后，我就幫助其他科學家來預測熔巖接著將往何處流去，流速是多少。
【句法分析】 having collected and evaluated the information是現在分詞的完成式在句中作狀語，表明從句動作發生在主句動作之前。
①having answered the teacher’s questions，she sat down and felt much more relaxed.
回答老師的問題后，她坐下來，感到輕松多了。
②having been separated from other continents for millions of years，australia has many plants and animals not found anywhere else in the world.由于與其他的大洲分離了幾百萬年了，澳大利亞有許多在世界上其他地方都找不到的動植物。
【溫馨提示】 過去分詞作狀語同現在分詞作狀語時一樣，其邏輯上的主語就是主句的主語，但所不同的是，過去分詞與主語之間存在被動關系，但有時無被動意味，只是表示一種狀態或動作的完成，而現在分詞與主語之間存在著主動關系。
③given better attention，the flowers could have grown better.
要是照看得好一點，這些花會長得更好。
④dressed in white，she looks really pretty.
穿著白衣服，她看起來真美。
⑤seeing the photo，he couldn’t help thinking of his good old days.看到那張照片，他禁不住想起了美好的往昔。
[即境活用]
12.________in the queue for half an hour，the old man suddenly realized he had left the cheque in the car.
a.waiting b.to wait
c.having waited d.to have waited
解析：選c。本題考查非謂語動詞。根據the old man與wait之間的關系，應該選擇v.ing形式，再根據句意得知他是先“wait”后才“realize”。所以先發生的動作應該用完成式having waited。
13.________there for some time，mr.johnson knew the place quite well.
