过去分词形式done 与所修饰的名词是逻辑上的被动关系或表已完成的动作
动词不定式to do 表示将要发生的动作
动词不定式的被动 形式to be done 表示将要被做的动作

参考答案
(1)frightening 句意:一个突然的停车可能是一种非常可怕的经历,尤其是如果你在高速行驶。句中动词frighten与其所修饰的名词experience是逻辑上的主动关系,故用现在分词做定语。
(2)spent 句意:吉姆已经退休了,但他仍然记得和学生们一起度过的快乐时光。句中动词spend与其所修饰的名词time是逻辑上的被动关系,故用过去分词做定语。
(3)to catch 句意:开会时我一直盯着钟,因为我要赶火车。动词不定式表将要发生的动作。
(4)dating 句意:没有人能忽视古代丰富的文化以前所未有的速度和规模向现代转变。句中动词词组date back to只用主动语态,故与修饰的名词culture是主动关系。

句式9 Einstein, who was Jewish, found the doors of academic institutions closed to him.爱因斯坦是犹太人,他发现学术机构的大门对他关闭了。
句式剖析
句中who was Jewish是who引导的非限制性定语从句;主句中“found the doors of academic institutions closed”是“find+宾语+宾语补足语”结构,宾语是the doors, closed是过去分词,在句中做宾语补足语,与宾语(the doors)是被动关系。
考点提炼
“find+宾语+宾语补足语”结构
该结构意为“发现……处于……状态”。在此结构中,宾语补足语可用以下形式:
find+宾语(n./pron.)+

特别提醒

句式9 Einstein, who was Jewish, found the doors of academic institutions closed to him.爱因斯坦是犹太人,他发现学术机构的大门对他关闭了。
句式剖析
句中who was Jewish是who引导的非限制性定语从句;主句中“found the doors of academic institutions closed”是“find+宾语+宾语补足语”结构,宾语是the doors, closed是过去分词,在句中做宾语补足语,与宾语(the doors)是被动关系。
考点提炼
“find+宾语+宾语补足语”结构
该结构意为“发现……处于……状态”。在此结构中,宾语补足语可用以下形式:
find+宾语(n./pron.)+
If you go to the Palace Museum, you’ll find many Chinese treasures exhibited there.如果你去故宫博物院,你会发现许多中国珍宝在那儿展览。
When I came in,I found all the students smiling at me.当我进来时,我发现所有的学生都冲着我微笑。
I went to visit her on my way home and found her out.我在回家的路上去拜访她,发现她出去了。
Thanks a lot for your book.I found it very interesting.谢谢你的书。我发现这本书很有趣。
特别提醒
当动词不定式做find的宾语时,通常用it做形式宾语,真正的宾语则放在宾语补足语之后,即构成“find+it(形式宾语)+宾语补足语+动词不定式(真正的宾语)”结构。
