1:want、would like等后面跟动词不定式,前面一个动词且没有系动词,的后面跟动词不定式。2:will 、be going to 后面跟动词原形3:句子的内容是过去的时候,用过去时,最典型的几个词是句子中有last、yesterday4:现在进行时动词加ING,主语+be+doing,一般句子中有look 、listen、now为现在进行时。like所在的句子表示一个长期的喜好时后面+doing,如果表示暂时性的后面加to do.热心网友 时间:2022-06-28 03:51
有将来性质在里面的可以用动词不定式,一些固定搭配也要用动词不定式.在过去发生的用过去式,完成时态的也要用完成时,即和过去式一样加ed.一般现在发生的就用动词原形,如果是正在进行,即强调这个动作正在做就要加ing,非谓语的主动语态做定语也是.热心网友 时间:2022-06-28 03:51
动词不定式指的是一些动词的过去式不像普通的动词一般+ed,原形的话,除有些特殊形式外现在时态时就用原形咯;过去式,很明显,就是指过去发生的事时用过去式,至于ing形式,就是正在做的事,就用ing热心网友 时间:2022-06-28 03:52
动词的形式的使用,主要是看当时那个动作发生的时间相对于现在是过去的,现在正在进行的还是将要做的,相对于现在这个动作已经发送了用过去式,动词不定式也就是to do的形式一般表示将要做的事情,ing则表示这个动作现在正在进行,原形,就有点难统一了,因为一般情况下原形则表示可观存在,但是有些特定情况下也是使用原形,比如be动词之后,表达的是真理等等情况。热心网友 时间:2022-06-28 03:53
非 谓 语 动 词 的 用 法 非谓语动词:在句子不作谓语使用的动词,其形式有不定式、现在分词、动名词和过去分词四种(通常我们把现在分词和动名词统称为-ing分词)。非谓语动词短语:非谓语动词仍保留动词的性质,可以有自己的宾语、表语或状语,我们将非谓语动词和其宾语、表语或状语一起称作非谓语动词短语。非谓语动词的判定方法:考虑句中谓语动词以及其它词语同非谓语动词的关系和对非谓语动词形式的*,以便选用正确的非谓语动词形式。非谓语动词判定的基本步骤:①是否应用-ing分词 ② 是否应用不带to的不定式 ③ -ing分词还是不定式④-ing分词还是过去分词 ⑤ 不定式的用法一、是否应用-ing分词:下列情况必须用-ing分词1、在下列动词(短语)之后作宾语或宾补时; Consider , dislike , enjoy , feel like , finish , imagine , mention , give up , mind , put off , can’t help , can’t stand , suggest , understand , be busy , have fun , have difficulty , have trouble, keep , spend , waste , have a hard time , find , look forward to , be use to(习惯于) ,prefer ( doing ) to ( doing ) ,take turns等。e.g When she heard the news, she couldn’t help crying. I found a boy playing in the corner.2、在介词之后作宾语时;e.g Lucy is good at swimming.3、作句子主语位于句首时;e.g Exercising every day is good for your health.4. 位于限定词后作名词使用时;e.g This is the beginning of the garden tour.5、在“go + -ing形式(运动名称)”和“ do some + -ing形式”这类固定短语中。e.g We will go fishing if it doesn’t rain tomorrow. She did some shopping last Sunday.6. –ing分词前逻辑主语的使用:有时我们需要在-ing分词前加上其动作的发出者(逻辑主语),其动作的发出者用名词所有格或形容词性物主代词表示。e.g Would you mind my smoking here?二、是否应用不带to的不定式: 下列情况必须使用不带to的不定式1、位于情态动词后同情态动词一起作谓语时;e.g You should see a dentist if you have got a toothache.2、位于would rather , had better , why (not)之后的不定式;e.g You had better stay here until the police come.Why not go to the movie with us?3、位于感官动词和使役动词后作宾补的不定式(注:help之后作宾补的不定式可以带to也可不带to);e.g I often hear her sing English songs in the next room. The boss made them work over 12 hours a day. She often helps her mother (to) do the housework.4、两个不定式由and , or , except , but 或 than连接在一起时,第二个不定式常常不带to。e.g I’d like to lie down and have a good rest.三、-ing分词还是不定式:1、动词like之后,使用不定式主要说明一次性的动作;使用-ing分词主要说明存在的状况。e.g I like playing soccer, but I don’t like to play it this afternoon.2、begin和start之后,-ing分词和不定式都可使用,但如果begin/start自身为-ing分词时,之后通常用不定式。e.g He began to do/doing his homework after dinner. I’m starting to cook dinner very soon.3、stop、remember、forget和go on之后的非谓语动词形式的判定,主要应考虑非谓语动词的动作在谓语动词动作前是否已发生:如动作发生在谓语动词的动作前,用-ing形式;如动作发生在谓语动词的动作后,用不定式。e.g The teacher is coming, please stop talking. On her way home, she stopped to buy some food for supper. Don’t forget to turn off the light when you leave. He did his homework again. He forgot doing it yesterday.4、need之后的非谓语动词形式的判定,主要考虑句子的主语同非谓语动词的关系:如句子的主语为非谓语动词的逻辑主语,用不定式;如句子的主语为非谓语动词的逻辑宾语,用-ing形式。e.g We need to water the flowers this afternoon. The flowers need watering this afternoon.5. 感官动词后的非谓语动词形式的判定,主要应考虑是说明整个动作(不带to的不定式),还是说明动作的一部分(-ing形式)。主要有下面几种情况:(1)句子中有表频率的词时,用不带to的不定式;e.g I often hear Lucy sing songs in the classroom.(2)look at以及see和hear的过去式后,一般用-ing形式;e.g I saw the children playing soccer on the playground.(3)watch之后,一般用不带to的不定式。e.g He sat there and watched them play basketball.四、-ing分词还是过去分词:1. 表伴随的插入语中的非谓语动词形式的判定,主要应考虑句子的主语同非谓语动词的关系:如句子的主语为非谓语动词的逻辑主语,用-ing形式;如句子的主语为非谓语动词的逻辑宾语,用过去分词。e.g When asked where she was from, she couldn’t help crying. Taking some papers in his hand, Mr. Smith hurried into the classroom.2. call和name位于名词后,其后带上人名、书名等词语时,用过去分词。e.g Do you know the boy named Jack Black? Yesterday we saw an action movie called Heroes.3. there be句中位于名词后的非谓语动词,如名词相当于动作发出者(主动式),非谓语动词用-ing分词,如名词为动作承受者(被动式),非谓语动词用过去分词。e.g Listen! There is someone crying for help. There is little time left. Let’s hurry up.五、不定式的用法(非上述四种情况时,非谓语动词一般都使用带to的不定式):1.不定式的否定形式:在不定式的小品词to前加否定词not。e.g The policeman told the boys not to play soccer in the street.2. 先行词it的使用:当不定式做句子的主语时或做句子的宾语其后带有宾补时,为保持句子结构的平衡,通常将不定式放在句子末尾,而在原主语或宾语的位置上加上先行词it。 e.g It is necessary for us to read English every morning. I found it necessary for us students to read English every morning.3. “wh-词+不定式”的用法:wh-词(特殊疑问词)同不定式连用相当于一个wh-词所引导的一个宾语从句,使用时应注意以下原则: ①如wh-词为疑问代词(what、which、who、whom或whose)时,不定式动词应为及物动词,但不带宾语(wh-词相当于不定式动词的宾语),如不定式动词为不及物动词,应带上适当的介词。 e.g There were too many things on sale. I didn’t know what to buy. I really don’t know what to talk about at the meeting.②如wh-词为疑问副词(how、when、where等)时,不定式短语中不能再出现表示相同关系的词语;另:如不定式动词为及物动词时,其后必须带上宾语。 e.g I don’t know how to do it.③如wh-词为连词whether时,不定式短语中应有表示选择的部分,否则不定式短语应用or not结尾。 e.g He wants to know whether to go to a movie or stay at home. I wondered whether to buy a computer or not. 一般情况下,我们应记住三个短语:what to do、how to do it和which to choose。 4. 不定式的逻辑主语:不定式动词仍保留动词的特性,也有自己的主语(不定式动作的发出者),我们将不定式动作的发出者称为不定式的逻辑主语。 不定式的逻辑主语通常是句子的主语或间接宾语: e.g He went to the town to buy some book yesterday. He asked me to have dinner with him this afternoon. 有时不定式的逻辑主语不是句子的主语或宾语(不定式作主语时),我们应在不定式前使用介词短语for s.b/of s.b为其加上逻辑主语: e.g It’s necessary for us students to study English well. It’s very kind of you to help me so much. 注:逻辑主语前介词for和of的选用,应考虑其前形容词的作用。如其前形容词用来说明不定式,逻辑主语前的介词用for,如说明逻辑主语,介词用of。 5. 不定式的逻辑宾语:有时句子中不定式前的某个词语相当于不定式的宾语,我们将其称为不定式的逻辑宾语,此时不定式的动词应为及物动词或及物动词词组(动词为不及物动词时,应加上适当的介词),但不能再带宾语。 e.g 错:The question is too difficult for me to answer it. 对:The question is too difficult for me to answer. 错:The computer is too expensive for me to pay. 对:The computer is too expensive for me to pay for. 6. 不定式位于名词后作定语:不定式位于名词后作定语使用时应注意考虑名词同不定式的关系。①名词相当于不定式的逻辑主语:e.g He is the first Chinese pianist to win this prize.②名词相当于不定式的逻辑宾语:此时不定式的动词应为及物动词或及物动词词组(动词为不及物动词时,应加上适当的介词),但不能再带宾语。e.g Today we have much homework to do.③名词相当于不定式的状语:此时不定式应以介词结尾(因为名词不能直接作状语,而应在其前加上适当的介词构成介词短语用来作状语,说明地点、方式等,所加的介词这时放在不定式后)。 e.g First we have to find a restaurant to eat dinner in. He wants to find a partner to practice English with.
