2、ood for your health. 不定式：一次性、具体性动作To solve all the problems at once is impossible. 注：当动名词或不定式做主语时，更多的是用 it 做形式主语而把真正的主语转成不定式置 于句末。It is good for your health to do exercises regularly. It is impossible to solve all the problems at once. 某些特殊的形式主语结构，依然和动名词连用。It is no use/good crying over the spilt mil
3、k. 三、做宾语的非谓语动词比较 类别 词例（仅限至本单元止已学过的动词，后学的请补充） 只与动名词连用：admit, dislike, imagine, delay, consider, mind, understand, avoid, enjoy, practise, miss, finish, keep, suggest, risk, overlook, advise, allow, forbid, appreciate, advocate, resist, stand, put off, cant help, feel like, be worth 只与不定式连用：agree, beg
4、, dare, decide, expect, fail, happen, hesitate, hope, intend, manage, prepare, pretend, promise, refuse, swear, wish, plan, get, help 两者皆用无区别：continue, prefer, begin, hate, start, love 两者皆用有区别：forget, remember, regret, mean, try, go on, like, need/want/require 注：介词短语后面只接动名词，尤其关注介词 to 后接动名词的情况，易与不定式混
5、淆。 如：pay attention to, look forward to, be/get used to, be related/linked to, be the key to, be on ones way to, make contributions to, devoteto, thanks to, in addition to, object to, preferto(仅限至本单元止已学过的动词，后学的请补充)尤其关注后接不定式和动名词时，区别很大的动词。 I forgot to return the money to you. 我忘记要还钱给你了。 （钱未还） I forgot
6、returning the money to you. 我忘记已经还过你钱了。 （钱已还） The headmaster have meant to put off the sports meeting. 校长打算推迟运动会。 The heavy rain means putting off the sports meeting. 大雨意味着运动会推迟了。 Tom tried to walk again after his leg was badly hurt.（Tom 努力地行走） If you feel too full, you can try walking after a meal.
7、 （你可以尝试着走走）The computer needs repairing. = The computer needs to be repaired. 有些动词接动名词做宾语，但接不定式做宾补。I consider buying a computer. I consider computers to be a useful tool of communication. We dont allow smoking here, so you are not allowed to smoke here. Our theatre forbids taking dogs in. We forbid
8、people to take dogs in. He advised asking our teacher for help. He advised us to ask our teacher for help. 四、做宾语补足语的非谓语动词比较（适用“解题思路” ） 类别 与宾语的逻辑关系 例句 不定式：过程性、即将发生 I often hear her sing next door. (唱的过程) We invited her to sing for her mum. (即将唱) 现在分词：主动性、正在进行 I heard her singing next door. (正在唱) 过去分词
9、：被动性 I often hear the song sung by children. (被唱) 注：某些动词接省 to 不定式做宾补，主要有一感(feel)，二听(hear, listen to)，三让 (make, let, have)，六看(see, watch, look at, observe, notice, find)，半帮助(help)。但改为被动语态时，要将省略的 to 补出。I often hear her sing next door. She is often heard to sing next door. 很多形容词和名词做宾补的结构可以看作 to be 不定式的
10、省略。Hard work has made him (to be) a great man. We consider Tom (to be) the cleverest in our class. 一般不用 being done, having been done 做宾补。 如：I often hear the song being sung by them. () 五、做表语的非谓语动词比较 类别 注意点 例句 动名词：解释说明 名词用法His habit is going to bed early and getting up early. 不定式：解释说明My advice is to
11、ask your teacher for help. 计划打算：动词用法They are to start for New York tomorrow morning. 现在分词：现在进行时Tom was doing his homework when I came in. 过去分词：被动语态Much homework is given to us every day. 注：区分动名词还是现在分词做表语的一个简单方法“主表颠倒法” 。 动名词和不定式都可以做表语，解释说明主语的具体内容，但动名词更强调动作的经常性 和习惯性，不定式则侧重于一次具体的行为。 My job is looking a
12、fter the twins. 我的工作是照顾这对双胞胎。(此人是保姆) Today my job is to look after the twins. 今天我的任务是照看这对双胞胎。 （临时帮忙）不定式、现在分词、过去分词做表语的动词用法，适用“解题思路” 。 表达正在进行的被动时，用现在分词的被动形式“being done”做表语。Many sea creatures are being wiped out by fishing boats. 六、做定语的非谓语动词比较（适用“解题思路” ） 类别 逻辑关系 例句 不定式：即将发生the scientist to visit our sc
13、hool 现在分词：主动性、正在进行the visiting scientist at our school 过去分词：被动性、已经完成the visited school by the scientist 动名词：用途、属性、特征a swimming pool, a guessing game 注：动名词和现在分词做定语的区别：前者强调用途属性，后者强调动作正在进行。a swimming boy= a boy who is swimming a swimming pool= a pool which is used for swimming 非谓语动词做定语可以转化为定语从句，从句中谓语动词
14、与关系词的逻辑关系 和非谓语动词与中心词的逻辑关系完全一致。 a scientist to visit our school = a scientist who will visit our school (即将访 问) a visiting scientist at our school = a scientist who is visiting our school (正 在访问)the visited school by the scientist = the school which is visited by the scientist (被访问) 当中心词被 only, last,
15、 next, 序数词和形容词最高级修饰时，只用不定式做定语。 Who is the first person to discover that the earth circles the sun? (此处不用discovering) 当不定式做定语时，主被动形式皆可；但如果出现了不定式的逻辑主语时，用 主动形式，不用被动形式。There is much work to do/ to be done. There is much work for me to do. I have much work to do. (此两句不用 to be done) 及物动词的过去分词体现被动关系，不及物动词的
16、过去分词体现动作已完成。the broken bike= the bike which is broken the beaten boy= the boy who was beaten the retired worker= the worker who has retired the fallen leaves= the leaves which have fallen 选择分词做定语关键看逻辑关系主动还是被动？正在发生还是完成？ a developing country (发展中国家) a falling leave (空中的落叶) a developed country (发达国家) a fallen leave (地上的落叶) boiling water (沸水) the escaping prisoner (正在越狱的囚犯) boiled water (凉开水) the escaped prisoner
