Let's hurry up. 剩余时间不多了，咱们快点吧。 [名师点津]　有些过去分词表示特定含义，单独作定语也放在被修饰的名词之后，如 left(剩余的)，given(所给的)，concerned(有关的)等。另外，单个过去分词作定语修饰代词时，应该放在被修饰词的后面。 2．有些过去分词作定语既可前置也可后置，意义不变，但有些过去分词置于被修饰词前后的位置不同，则意义也不相同。 All the broken windows have been repaired.＝ All the windows broken have been repaired. 所有坏了的窗户都已经修理好了。 The method used is very efficient. 所用的这个方法很有效。 This is a used car worth only 5,000 yuan. 这是一辆只值 5 000 元的旧车。 [名师点津]　有些表示情感或心理状态的过去分词已经完全形容词化，常见的这类过去分词有：disappointed(失望的)，moved(感动的)，interested(感兴趣的)，surprised(感到惊讶的)，shocked(震惊的，震撼的)，puzzled(迷惑不解的)，frightened(受惊吓的)等。 ◆[针对训练] 　单句语法填空 ①Most of the suggestions　 made　(make) at the meeting were not very practical. ②Look! The students 　seated　(seat) at the back of the classroom are playing computer games. ③She only eats fruit 　grown　(grow) on her own farm. ④Who is the girl 　absorbed　(absorb) in reading a book under the tree? ⑤Those　 infected　(infect) have been taken to hospital. 二、过去分词作定语时的意义 1．及物动词的过去分词作定语时，在语态上表示被动；在时间上，常表示动作已经发生或完成。有时只表示被动。 He is a teacher respected by all the students. 他是一位受所有学生尊敬的老师。(只表示被动) The plan put forward at the meeting will be carried out soon. 会上提出的计划将很快被执行。(表示被动和完成) 2．不及物动词的过去分词作定语时，不表示被动意义，只强调动作完成。 The risen sun is shining brightly in the morning. 早晨，升起的太阳明亮地照耀着。 When I woke up the next morning，I found the ground was covered with fallen leaves. 当我第二天早上醒来时，发现地上全是落叶。 ◆[针对训练] 　汉译英 ①受感动的学生们　　　　　moved students　 ②一台坏了的计算机 　a broken computer　 ③—箱埋起来的硬币 　a buried box of coins　 ④浇过的花 　watered flower　 ⑤与朋友度过的快乐时光 　the happy time spent with friends　 三、过去分词与其他非谓语动词作定语的区别 形式 时态意义 语态意义 过去分词 done 表示已完成 被动 现在分词 doing 表示正在进行 主动 现在分词 的被动式 being done 表示正在进行 被动 不定式 to do 表示将要发生 的动作 主动 不定式的 被动式 to be done 表示将要发生 的动作 被动 　All the books borrowed from the library must be returned next Saturday. 所有从图书馆借的书都得在下星期六归还。 The man planting trees in front of the building is our teacher. 在大楼前面植树的那个人是我们的老师。 The building built last year is our library. 去年建造的那栋楼是我们的图书馆。 The building being built now is our library. 现在正在建造的那栋楼是我们的图书馆。 The building to be built next month is our library. 下个月将要建造的那栋楼是我们的图书馆。 ◆[针对训练] 　单句语法填空 ①(2019·天津高考)Most colleges now offer first­year students a course specially 　designed 　(design)to help them succeed academically and personally. ②The idea 　presented　(present ) by Peter is much simpler. ③This is the problem 　being discussed　(discuss)at the meeting now. ④The bridge 　to be constructed　(construct)next year will be of great importance. ⑤The policies 　to be passed　(pass) will benefit the farmers a lot.
