【答案】A
1. A study of travelers __________ （conduct）by the website TripAdvisor names Yangshuo as one of the top 10 destinations in the world.
【错因分析】conducting。有的考生以为此处为-ing形式作后置定语而误填conducting。 【试题解析】根据句意和句子结构可知，study和conduct之间为被动关系（同时注意空格后的介词by），所以使用过去分词作后置定语。 【参考答案】conducted。
过去分词只有一种形式：规则动词由动词原形加词尾-ed构成。不规则动词的过去分词没有统一的规则要求，要一一记住。
过去分词作定语
?Our class went on an organized trip last Monday. 上周一我们班开展了一次有组织的旅行。
?Those selected as committee members will attend the meeting. 当选为委员的人将出席这次会。
2
注意
当过去分词是单词时，一般用于名词前，如果是过去分词短语，就放在名词的后面。过去分词作定语相当于一个被动语态的定语从句。
动名词作定语和动词不定式作定语
动名词作定语往往表示被修饰词的某种用途。如：
?a walking stick =a stick for walking=a stick which is used for walking ?a washing machine=a machine for washing=a machine which is used for washing ?a reading room=a room for reading=a room which is used for reading
不定式作定语通常要放在被修饰的词后。 ?I have a lot of work to do. 我有很多工作要做。
2. What makes the adobe dwellings admirable is their ability to ＂air condition＂ a house without ________（use）electric equipment.
动名词和现在分词的同与不同
相同之处：它们都是由动词变化而成的，它们都保留了动词的某些特征，它们都能带自己的宾语、状语，而构成动名词短语或是现在分词短语去担当句子成分。
?Speaking in the public, he will surely be very cheerful. 能做演讲，他肯定很开心。（现在分词短语，作状语）
?She hates speaking in the public. 她讨厌做演讲。（动名词短语，作宾语）
区别：
1）动名词和现在分词都可以用于系动词之后作表语，区别方法是：
a. 作表语的动名词与主语指的是同一件事，此时系动词相当于＂是＂，通常把主语和表语的位置互换，语法和意思不变。
?My hobby is swimming.可改为：Swimming is my hobby. 我的爱好是游泳。
b. 现在分词作表语主要用以说明主语的性质,不能与主语互换位置，例如：
2
?The story is interesting. 不可改为：Interesting is the story. 这个故事很有趣。 2）动名词和现在分词都可以用作定语来修饰名词，区别在于：动名词修饰名词时主要表示该名词的用途，而现在分词修饰名词时表性质、状态或动作等。比较：
a swimming boy 一个正在游泳的男孩，即a boy who is swimming，现在分词swimming表示被修饰名词boy的动作。 a swimming suit 游泳衣，即a suit for swimming，动名词swimming表示suit 的用途。 常见考法
1. 动名词做主语时，谓语动词的数；
2. 在动名词和不定式中，作为介词的宾语是动名词；
3. 动名词的否定直接在其前加否定词，通过代词的宾格或所有格形式给出逻辑主语； 4. 有些词后只能接动名词；
5. 另外还有一些接-ing形式的常用说法。 误区提醒
1. 动名词(短语)作主语，谓语数用错； 2. to作不定式符号和介词分不清； 3. 否定形式not位置不对； 4. 动名词和现在分词的用法弄混；
5. 只接动名词的动词和短语、句型识记不完整。
1.(2018·北京卷·单项填空) Ordinary soap, _________ correctly, can deal with bacteria effectively.
A. used B. to use C. using D. use 【答案】A
【解析】考查非谓语动词。句意：如果正确使用的话，普通的肥皂可以有效地处理细菌。Ordinary soap can deal with bacterial effectively是主句，_________ correctly是条件状语，修饰ordinary soap，ordinary soap和use之间是被动关系，故要用过去分词，A选项正确。
