1.為什么有的動詞放在句首要用
動詞-ing放在句首是做動名詞主語。
此時它不再是動詞的性質,而是名詞的性質,因此叫做動名詞。 當然有時你會發現放在句首的不是動名詞而是動詞的過去分詞。
具體判斷到底是用哪種形式要根據動詞與后面的中心詞或者主語是什么關系,是主動的還是被動的。主動的就用ing,被動的就用ed。
例如: WAlking in the rain,he felt cold。因為WAlking和he之間是主動關系。
Tied back,his hands couldn't be seen。 因為Tied和his hands之間是被動關系。
2.為什么英語動詞要加ing??
be動詞(*).介詞后面加ing形式。還有固定的詞組搭配要記住
某些動詞后出現非限定性動詞時只能用動名詞作賓語,不能用不定式。常見的此類動詞有:advise, allow, permit, avoid, consider, enjoy, finish, give up, cannot help, imagine, include, keep, keep on, mind, miss, put off, delay, practise, resist, suggest, depend on, think about, set about, succeed in, worry about, burst out, insist on, can't stand, be used to, get used to, devote…to…, look forward to, pay attention to, get down to等。如:
They went on walking and never stopped talking. 他們繼續走,說個不停。
I found it pleasant walking along the seashore. 在海灘上走真是樂事。
(2)作介詞的賓語
We are thinking of making a new plan for the next term. 我們正考慮為下學期制定新的計劃。
Shall we have a rest or get down to doing our work? 我們休息呢還是開始干活?
(3)作形容詞的賓語
The music is well worth listening to more than once. 這種曲子很值得多聽幾遍。
We are busy preparing for the coming sports meet. 我們正為馬上到來的運動會忙著做準備。
3、作表語
動名詞作表語時句子主語常是表示無生命的事物的名詞或what引導的名詞性從句。表語動名詞與主語通常是對等的關系,表示主語的內容,主語、表語可互換位置。
Your task is cleaning the windows. 你的任務就是擦窗戶。(Cleaning the windows is your task.)
What I hate most is being laughed at. 我最痛恨的就是被別人嘲笑。 (Being laughed at is what I hate most.)
4、作定語
動名詞作定語往往表示被修飾詞的某種用途。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
a measuring tape=a tape for measuring=a tape which is used for measuring
sleeping pills=pills for sleeping=pills which is used for sleeping
3.為什么英語有句子里的單詞要加ing
ing形式,有很多用法,進行時,做定語,做狀語,等等,語言的用法很靈活的,各種活用,很多的,就拿ok來說,既可以做動詞(my boss oked my plan。),又可以做形容詞(it's ok!),漢語言里面也有很多這種用法,如”活動“這個詞,可以做動詞(活動一下筋骨),也可以做名詞(參加體育活動),文言文里面更多,名詞活用(《戰國策·馮諼客孟嘗君》中的“孟嘗君客我”意思就是
客作為宴請的意思),現在常說的”客居“,其實也是活用,”以客人的身份居住“,還有使動用法,意動用法等等,你別糾結了,而且一種語言的形成是許多年,中間體現了人們多年的習慣用法和文化,不能較真,”沒有為什么“,語言不是數學,不能完全用邏輯來思考
4.英語中動詞加ing的用法明天上課老師要提問的
1、-ing分詞的構成-ing分詞是由動詞原形加詞尾-ing構成.-ing分詞同樣有時態和語態的變化,通常有下表幾種形式(以do為例):一般式 完成式主動形式 doing 主動形式 having done被動形式 being done 被動形式 having been done-ing分詞的否定形式是由not 加-ing分詞構成.如:Not knowing his address, I could do nothing but stay at home and wait.不知道他的地址,我只好在家里等著.His not coming made all of us angry. 他沒來使我們大家都很生氣.2. -ing分詞的一般式和完成式:-ing分詞的一般式表示和謂語動詞所表示的動作同時進行的動作;完成式表示在謂語動詞所表示的動作之前發生的動作.如:Being a student, he was interested in books. 作為一個學生,他對書本很感興趣.Not having studied his lessons very hard, he failed the examinations. 因為沒有努力學習功課,他考試不及格.3. -ing分詞的被動式:-ing分詞的被動式表示它的邏輯主語是-ing分詞動作的承受者.根據-ing分詞動作發生的時間,-ing分詞的被動式有一般被動式(being done)和完成被動式(having been done).如:The question being discussed is very important. 正在被討論的問題很重要.Having been criticized by the teacher, he gave up smoking. 被老師批評以后,他把煙戒了.注意:在need, want, require, be worth等動詞(短語)后,作賓語的-ing分詞常用主動形式來表示被動含義.如:Your shoes need cleaning. = Your shoes need to be cleaned. 你的鞋需要清洗一下了.This book is well worth reading. 這本書很值得一看.4. -ing分詞的語法作用 -ing分詞一方面具有動詞的性質,另一方面也相當于一個名詞或形容詞、副詞,在句中可以作主語、表語、賓語、定語、狀語和補語等.1)–ing分詞(短語)作主語:Laying eggs is the ant queen's full-time job. 產卵是蟻后的專職工作.Saying is easier than doing. 說比做容易.在下面兩種結構中,-ing分詞也作主語.①為了保持句子平衡,通常用作形式主語,而把真實主語放在句末.如:It is no use crying over spilt milk. 作無益的后悔是沒有用的.It's a waste of time arguing about it. 辯論這事是浪費時間.②在There is no結構中,通常用-ing分詞.如:There is no joking about such matters. 這種事開不得玩笑.There is no holding back the wheel of history. 歷史車輪不可阻擋.2) -ing分詞(短語)作表語:His hobby is collecting stamps. 他的愛好是收集郵票.The problem is quite puzzling. 這個問題很令人困惑.3) -ing分詞作賓語:①–ing分詞作動詞賓語.如:I suggest doing it in a different way. 我建議用另一種方法做這件事.We enjoy attending Miss Li''s class. 我們喜歡聽李老師的課.②-ing分詞作賓語也可用在復合賓語中作真正的賓語,而用it作形式賓語.如:I don't think it possible living in such a cold place. 我認為住在這么寒冷的地方是不可能的.Do you consider it any good trying again? 你覺得再試一次會有好處嗎?③-ing分詞作介詞賓語,經常用在一些短語的后面.如:I'm against inviting him to dinner. 我反對邀請他來吃飯.They don't feel like walking that much. 他們不喜歡走那么多路.此類短語還有很多.如:look forward to(渴望,盼望), be proud of(以……自豪), be responsible for(對……負責), insist on(堅持), think of(考慮,想到), dream of(夢想), object to(反對,抗議), hear of(聽說), prevent…from(防止,阻止), keep…from(防止,阻止), stop…from(防止,阻止), be engaged in(從事于), depend on(依靠,依賴), thank…for(因……而道謝), excuse…for(因……而道歉), aim at(目的在于), devote…to(獻身于), set about(著手做), be/get used to(習慣于), be fond of(喜歡), be afraid of(害怕), be tired of(對……厭煩), succeed in(成功地做……), be interested in(對……感興趣), be ashamed of(對……感到羞愧)等等.注意:在有些句子中,介詞常可省去.如:I have no difficulty (in) communicating with foreigners. 我在和外國人交談方面沒有什么困難.He used to spend a lot of time (in) playing games. 過去他常花很多時間玩游戲.What can prevent us (from) getting married? 有什么能阻止我們結婚?另外,-ing分詞可以和一些介詞如in, on, after, against, before, by, for, without, besides等構成短語,在句中作狀語.如:He left ahead of time without saying a word. 他一句話也沒說就提前離開了.Besides cooking and sewing, she had to take care of four children.除了做飯和縫紉以外,她還要照顧四個孩子.On hearing the news, all the pupils jumped with joy. 聽到這個消息后,所有的學生都高興得跳了起來.4) -ing分詞作定語:①單個的分詞作定語一般放在被修飾詞的前面.如:reading room 閱覽室 swimming pool 游泳池 dining car 餐車sleeping car 臥車 singing competition 歌詠比賽 waiting room 候車室②-ing分詞短語作定語應放在被修飾詞的后面,也相當于一個定語從句.如:Who is the comrade standing by the door? 站在門邊的同志是誰?They 。
