2. 常作the only, the best, the last, the next等以及名词ability, chance, idea, hope, wish, fact, excuse, promise, attempt, way等名词后面。
3. 不定式和所修饰词是被动关系，能在这句话中找到它的执行者，则有不定式的主动式，找不到则用被动式。
现在分词 表示正在进行的动作或状态在持续中 主动式或被动式 1. 单个的现在分词和过去分词一般为前置定语，分词短语为后置定语。
2. 分词短语用逗号隔开为非限制性定语，无逗号为限制性定语。
3. 部分不及物动词的过去分词作定语，仅表示完成，无被动。如fall, rise, develop, boil, return, retire等。
4. 部分动词的分词已经形容词化，形容“物”，常用现在分词，表示“人”的状态，包括人的表情（expression, look), 眼神（eye）、嗓音（voice）等，用过去分词。如surprise, amaze, astonish, frighten, terrify, move, touch, tire, born, interest, excite, satisfy, puzzle, confuse, disappoint, encourage, convince, worry, depress等。

动名词 前置定语，表示被修饰名词的用途或功能 5. 部分短语动词没有被动语态，常用现在分词作定语， belong to, consist of, date back to/date from 等。

Activity 3 三种非谓语作状语
用法
不定式 1. 不定式作目的状语，三种形式to do, in order to do, so as to do。从位置上讲to do和in order to do可放在前或后面，so as to do只能放在后面。in order not to do/so as not to do成立，而to do没有否定式。
2. 不定式作结果状语，有(only) to do, too... to do, ...enough to to, so/such...as to do形式。
3. 不定式作原因状语，主要用于下面句型：be +adj(常见good, kind, glad, happy, surprised, frightened ...) to do句式中。
分词 1. 分词可以作原因、伴随、时间、结果、方式、条件、让步等状语。
2. 如果分词与句子的主语之间有主谓关系，则用现在分词，如果分词与句子的主语之间有动宾关系，则用过去分词。
3. 分词可以加上连词，构成“连词+分词”形式。常见的连词有：when, while(只能加doing)，till, until, if, once, unless, though, although, even if(though), as, than等。
4. 有些动词的过去分词已经形容词化或者是细表结构，这类分词作状语时，既不表示被动，也不表示完成，而表示一种状态。常见的有lost, seated, hidden, lost, absorbed, exposed, located, situated, dressed, tired, interested, excited, surprised, disappointed, worried, embassassed, depressed, satisfied, moved等。
5. 分词的独立结构：有一类现在分词和过去分词（短语）作状语，用来修饰全句。常见的有：speaking of, talking of, considering, taking sth into account/consideration, supposing that, judging from/by, providing/provided that(假定）, given...(考虑到）, generally/personally/franky/ttruly...speaking等。
异同点: 从上面表格可以看出，不定式和分词作状语只在原因状语和结果状语上有交集，不定式作原因状语是固定句式。另外不定式作结果状语，表示“意料之外，出乎意料”，而现在分词作状语，表示“意料之内，自然而然”。

2. 在感官类动词后面，表示动作的全过程，且在一下动词后面，常省略”to”，变成被动句，还原“to”。常见动词：一感（feel)，二听（hear, listen to)，五看（see, notice, observe, watch, look at)。
3. 在使役动词后，表示一次性具体动作，常见用have, get, make, let, leave等。
