这是个由what引导的宾语从句，不用再接介词了

owe to[英][əu tu:][美][o tu]欠…（某物）; 应该感谢，把…归功于; 用法：owe... to...与attribute... to...有一个很重要的区别就是:owe... to...的主语既可以是人，也可以是物；而attribute... to...的主语则只能是人。另外， owe... to...只用于主动句，大都与褒义词连用。例如：He owes his success to his father. 他把他的成功归功于他的父亲。Jim attributes his success to hard work. 吉姆把他的成功归功于努力工作。

　　区别是：　　in 英[u026an] 美[u026an]　　prep. 采用（某种方式）; 穿着，带着; （表示位置） 在…里面，（表示领域，范围）在…以内; （表示品质、能力等） 在…之中;　　adv. 在家; 进入，到达; 流行; 当选;　　adj. 在内的，朝内的; 在位的，执政的; [口语] 流行的，时髦的; （车等） 到站的;　　[例句]He was in his car.　　他坐在他的车里。　　on 英[u0252n] 美[ɑ:n]　　prep. （表示方向） 向; （表示对象） 对; （表示位置） 在…上; （表示时间） 在…之时;　　adv. （放，穿，连接） 上; 向前，（继续）下去;　　adj. 活动着的情况，状态; 使用着的; 发生着的; 计划中的;　　[例句]He is sitting beside her on the sofa.　　他挨着她坐在沙发上。　　in和on的用法是：　　in可表时间，表地点，表手段、方法、材料。　　（1）in表示时间，用于泛指一天的上午、下午、晚上等；用于某个较长的时间，如年、月、季节等。如：　　in the morning／afternoon／evening在上（下午）或晚上，in 2003在2003年，in the day／daytime在白天　　in还可以表示“从现在起一段时间以后”。如：　　They will see you in a week．他们将在一周后去看你。　　另外，in和at都可以表示时间，但in表示较长的时间，而at表示时间的某一点。例如：　　He got up late in the morning and had a meal at noon．他早上起得晚，所以只吃午餐。　　（2）in表示地点、场所，译为“在......里”、“在......中”。如：in the factory 在工厂，in the room 在房间里，in the sun 在阳光下，in the middle of...在......的中央　　in和at都可表示地点，而in表示的地点比at所表示的地点大。　　（3）in表示用语言，用......材料。译为“用......，以......方式”。如：in English用英语，in ink用墨水　　（4）in表示穿戴的状态，译为“戴着、穿着”。如：in the white shirt穿着白色的衬衫，in the cap戴着帽子　　【相关链接】in表示“穿（戴）着”是介词，指状态，同wear一样。in后接表示服装类的名词或表示颜色的词。如：　　Kate is in a red skirt．／Kate wears a red skirt．凯特穿着红裙子。　　on　　介词on表示时间、地点、方位等。　　（1）on表示时间，用于星期、日期（包括该天的各部分）。如：on Sunday／Sundays，on Monday morning／afternoon／evening等。　　on也用于某一日的名词前，用于公共节假日前。如：　　On New Year"s Day 在元旦，on Children"s Day 在儿童节等。　　（2）on表示地点、位置，有“在......旁”、“接近”、“靠近”之意。如：　　a house on the main road 临大街的房子， sit on my right 坐在我的右边　　（3）on表示状态，译为“处于......情况中，从事于......”等。如：　　on duty 值日，on holiday 度假　　（4）on表示“在......上面”，用在表示物体的名词前。如：　　on the box 在盒子上　　on和over都是介词，on表示“在......上面”，指一物体与另一物体表面相接触；over表示“在......上方”，指一物体与另一物体不接触。试比较：　　There is a light on the desk．桌子上有盏台灯。（light与desk接触）　　There is a light over the desk．桌子上方有一盏灯。（light与desk不接触）　　表示“在......上”，介词on与in必须注意习惯用法，否则会出错。不妨比较一番：　　on the tree／in the tree都译为“......在树上”。前者表示树上本身所长着的叶子、花、果实等；后者表示某物或某人在树上。　　on the wall／in the wall都译为“在墙上”。由于介词不同，在使用上有区别。图画、黑板、风筝等“在墙上”，是因为它们在墙的表面上，故用on the wall；门窗、钉子、洞、孔等“在墙上”，是因为它们在墙的里面，故用in the wall.

lunar前面用什么介词答：lunar前面用介词on用作短语搭配。

Take this seat. 请坐这儿。

单词pity的可数性及其介词和句型搭配 　　导语：单词pity意为同情，它的可数性以及常用介词是什么，下面由我告诉大家，欢迎参考! 　　1. 表示一般意义的`“同情”“怜悯”等，是不可数名词。如： 　　I saved her out of pity for her child. 我出于对她小孩的同情才救她。 　　We were moved to pity by her suffering. 我们受她的痛苦所感动而产生同情。 　　表示具体意义的“可惜的事”“遗憾的事”等，是可数名词。如： 　　It seems a pity to give up now. 现在放弃好像很遗憾。 　　What a pity you canu2019t go with us! 真遗憾你不能和我们一道去。 　　2. 表示同情某人，其后通常用介词 for。如： 　　I feel no pity for you at all. 我一点也不同情你。 　　He was full of pity for the poor. 他很同情穷人。 　　但是，have (take) pity on 中通常用介词 on。如： 　　Do have [take] pity on me. 千万要可怜可怜我。 　　She took pity on him and gave him some money. 她同情他，给了他一些钱。 　　3. 在“Itu2019s a pity+that 从句”这一句式中，有时可省略句首的 Itu2019s a。如： 　　他没有及早想到这一点真是遗憾。 　　正：Pity that he didnu2019t think of this earlier. 　　正：Itu2019s a pity that he didnu2019t think of this earlier. 　　有时其后的从句可用虚拟语气，尤其是当从句有“竟然”之意时。如： 　　Pity [Itu2019s a pity] that you should have to leave. 你非走不可真是可惜。 　　Itu2019s a pity that he should have failed in the exam. 他竟然没有考及格真是遗憾。 ;

on

in+某年（或某月），on+某天（或某年某月某天），at+某时刻（或某年某月某时刻的早上）。其实我们就只需要抓住最小的时间，然后根据它来选择介词。其中，上面的某年某月某时刻的早上最小的时间是时刻，所以用介词at。

语法复习：介 词介词又叫前置词，是一种虚词。介词分为三种，一种是简单介词，如at, in, on, beside, to , for等；另一种是短语介词，即由两个以上的词组组成的短语，如in front of, because of, out of, instead of等；还有一种叫二重介词，如until after, from behind等。（一）介词的句法功能介词不能独立在句中做成份，介词后必须与名词、代词、或动名词构成介词短语在句中充当一个成份，表示人、物、事件等与其它人、物、事件等之间的关系。1、作定语：The book on the table is mine.2、作状语：We have breakfast at seven.（表时间）；They were late for meeting because of the heavy rain.（表原因）；They started the machine by pressing the button.（表方法）3、作表语：My dictionary is in the bag.4、作宾语补足语：I found him in the office.（二）介词分类（三）主要介词区别1、表示时间的at, in, on：at表示片刻的时间，如：at 8 o"clock ，常用词组有：at noon, at night, at midnight, at the end of, at that time, at the beginning of, at the age of, at Christmas, at New Year等。in表示一段的时间，如：in the morning, in the afternoon, in the evening, in October, in 1998, in summer, in the past, in the future等。on总是跟日子有关，on Monday, on Christmas morning, on the following, on May Day, on a warm morning等。2、表示时间的since和from：since表示从过去到现在的一段时间的过程，常与现在完成时连用。from表示从时间的某一点开始，不涉及与现在的关系。一般多与现在时、过去时、将来时连用。如：I hope to do morning exercises from today./ We have not seen each other since 1995.3、表示时间的in和after：两者都表示“在（某个时间）之后，区别在于in表示“在（一段时间）之后”，而after则表示“在（某一具体时间点之后）”，in短语和将来时态连用，after短语和过去时态或将来时态连用。如：We"ll be back in three days./ After seven the rain began to fall./ What shall we do after graduation?注意：after有时也可以表示在一段时间之后（常用在过去时里）。如：After two months he returned.4、表示地理位置的in, on, to：in表示在某范围内，on指与什么毗邻，to指在某环境范围之外。如：Changchun is in the northeast of China./ Mongolia is on the north of China./ Japan is to the east of China.5、表示“在……上”的on和in：on只表示在某物的表面上，而用in表示占去某物一部分。 如：There is a book on the piece of paper./ There is an interesting article in the newspaper./ He dug a hole in the wall.6、表示“穿过……”的through和across：through表示从内部通过，与in 有关；across则表示从一端至另一端在表面上的通过，与on有关。如： Water flows through the pipe./ The old man walked across the street.7、in the corner, on the corner, at the corner：in the corner 表示在角落里，in指角的内面；on the corner表示“在角上”，on指的不是内面，也不是外面，而含内外兼有之意；at the corner指“在拐角处”，at指的是拐角外附近的外面。如：The lamp stands in the corner of the room./ I met with him at the street corner./ He sat on the corner of the table.8、in the end, at the end of, by the end of：in the end作“最后”、“终于”解，可单独使用，后不接介词of；at the end of 表示“在……末梢”，“到……尽头”，既可指时间，也可以指地上或物体。不可单独使用；by the end of 作“在……结束时”，“到……末为止”解，只能指时间。不可单独使用。如：In the end they reached a place of safety./ At the end of the road stands a beautiful garden./ They decided to have an English evening at the end of this week./ by the end of last month he had finished the novel.9、表示“关于”的about 和on：两者都有“关于”的意思，不过前者为一般用词，而后者为较正式的“论述”。如：He came to tell me about something important./ He wrote a book on science.10、between, among：一般说来，between表示两者之间，among用于三者或三者以上的中间。如：You are to sit between your father and me./ He is always happy among his classmates.注意：但有时说的虽然是三个以上的人或东西，如果强调的是两两相互间接关系，适用于between。如：Agreements were made between the different countries. 在谈到一些事物或一组事物，而把它们视为分居两边时用between。如：The little valley lies between high mountains.。在谈事物间的差别时，总是用between。如：They don"t know the difference between wheat, oats and barley.11、besides, except, but, except for：besides指“除了……还有，再加上”。如：All went out besides me.；except指“除了，减去什么”，不能放在句首。如：All went out except me.；but 与except意思近似，表示“除了……外”经常用在no, all, nobody, anywhere, everything等和其他疑问词后面。如：I never saw him reading anything but the newspaper.；except for表示“如无……就，只是”表明理由细节。如：His diary is good except for a few spelling mistakes.。12、表示“用”的in和with：表示工具的“用”，用with，而表示材料、方式、方法、度量、单位、语言、声音等的“用”，用in。如：He is writing a letter with a pen./ He wrote the letter in pencil./ We measured it in pounds./ Read the text in a loud voice./ Tell me the story in English.13、in charge of和in the charge of：两者都表示“由谁负责、照顾、管理”。区别在于：in charge of后接被照管的人或物，而in the charge of后面则跟照管的人。如：Who is in charge of the project?/ The project is in the charge of an engineer.。14、as, like：as作“作为”、“以……地位或身份”解。如：Let me speak to you as a father.（事实是父亲）；like作“象……一样”解。如：Let me speak to you like a father.（事实上不是父亲）。15、in front of 和in the front of：in front of = before，是“在……前面”的意思（不在某物内）； in the front of则是“在……前部”的意思（在某物内）。如：There is a desk in front of the blackboard./ The boy sat in the front of the car.。16、in, into：into表示动向，不表示目的地或位置。如：We walked into the park.；in通常表示位置。如：We walked in the park；in和drop, fall, put, throw, break等终止性动词连用时，也可以表示动向。如：I have put the coin in (into) my pocket.我把硬币放进衣袋。

“介词+which”和where作为关系词引导从句的可代替性和不可代替性问题值得引起我们注意。它们二者之间有时可以替换使用,有时则根本不可能替换。因此,对它们的内涵进行一定剖析,以及对它们在句中所作功能进行对比归纳显得尤为重要。

关于“介词 + which / whom”引导的定语从句“介词+关系代词”引导的定语从句，是定语从句一种介词前置的定语从句句型，介词与关系代词之间存在一种介宾关系。当关系代词在定语从句中作介词宾语时，把介词置于关系代词前，即演变出“介词+关系代词”句型。例如：The man who/whom /that you spoke to is a teacher.=The man to whom you spoke is a teacher.一、基本构成1.“介词+关系代词”结构引导的定语从句中，关系代词只能用which（指物）或whom(指人) ，即：介词+which/whom。（1）The man to whom you spoke is a teacher.（2）The city in which she lives is far away.（3）The little girl is reading a book, in which there are many cartoons.注意：当介词放在关系代词的前面时，用在介词后的关系代词不能省略。2.在限制性定语从句中，当介词置于定语从句的谓语动词之后时，可用that/which(指物)；that/who/whom（指人）作介词的宾语.且此处关系代词可以省略，特别是在口语中。如：（1) The man (who/whom /that )you spoke to is a teacher.（2）The city（which/that）she lives in is far away.注：通常介词放在定语从句中动词后，也可以放在关系代词前面，但有些特殊动词短语搭配不能拆分，介词只能放在动词后，如： look for, look after, pay attention to ,take care of , look forward to, listen to等。This is the pen that / which you are looking for.The patient whom she is looking after is her father.The words that /which we should pay attention to are written on the blackboard.There are fifty patients who/whom/that we must take good care of.二、关系副词when，where，why可用“介词＋which”来代替。关系副词实际上是介词＋先行词。其中when=表时间的介词（如：in，at,during等）+which；Where=表地点的介词（如：in，at,on,under等）+which；Why=表原因的介词（如：for）+which(1)当先行词表示时间，定语从句中缺少时间状语时，通常用关系副词when引导，此时也可选用表示时间的介词＋which来代替关系副词when。I still remember the day when I came here. ( on the day =when) (2)当先行词表示地点，定语从句中缺少地点状语时，通常用关系副词where引导，此时也可选用表示地点的介词＋which来代替关系副词where。This is the house where I lived last year. ( in the house= where)(3)当先行词为reason，定语从句中缺少表示原因状语时，通常用关系副词why引导，此时也可以用for which来代替关系副词why。There are many reasons why people like traveling. (for the reasons =why)三、关系代词前介词选择三原则：一先，二动，三意义（重中之重）1.一先，即根据定语从句中介词与先行词的搭配关系选择。I never forget the day on which I came to this school. (on the day)2.二动，即根据定语从句中谓语动词与介词的搭配关系选择。This is the iPad on which I spent 3000 yuan. (spend money on sth.)3.三意义，即根据定语从句的意义来确定介词。This is my pair of glasses, __without which__I cannot see clearly.例题：用“介词+关系代词”的形式表示1. Do you like the book __________ she learned a lot? 2. He paid the boy $10 for washing ten windows, most ______ hadn"t been cleaned for at least a year.3. The tower _________ people can have a good view is on the hill.注意：介词+关系代词1）介词后面的关系代词不能省略。2）that前不能有介词。3）某些在从句中充当时间，地点或原因状语的"介词+关系词"结构可以同关系副词when,where和why互换。

分类: 教育/科学 >> 外语学习 问题描述: survive in又是什么意思呢？单独用survive与用survive in有什么区别吗？谢谢 解析: survive(作及物动词时)有两个意思:1.比...活得长;2.经过...活/保存下来: Few of the houses survived the war没有一所房子经受住了战争的洗礼。 Surprisingly,John survived his younger brother出乎意料的是约翰竟然活得比他弟弟还长。（作不及物动词）活下来，幸存；残留Of the wounded,only three survived.伤员中只有三个活了下来。 至于您讲到的survive in，那个in并不是跟survive搭配的，而是跟它后面的单词组成介宾短语，例如：All of them survived in the jungle.他们中的所有人都从丛林里活着走了出来。 补充：survive on 依靠...活下来 survival time 存活期 survival index 存活指数 survival bond 残存债券 mean survival time (MST) 平均生存期 survival method 幸存法

survive(作及物动词时)有两个意思:1.比...活得长;2.经过...活/保存下来:Fewofthehousessurvivedthewar没有一所房子经受住了战争的洗礼。Surprisingly,Johnsurvivedhisyoungerbrother出乎意料的是约翰竟然活得比他弟弟还长。（作不及物动词）活下来，幸存；残留Ofthewounded,onlythreesurvived.伤员中只有三个活了下来。至于您讲到的survivein，那个in并不是跟survive搭配的，而是跟它后面的单词组成介宾短语，例如：Allofthemsurvivedinthejungle.他们中的所有人都从丛林里活着走了出来。补充：surviveon依靠...活下来survivaltime存活期survivalindex存活指数survivalbond残存债券meansurvivaltime(MST)平均生存期survivalmethod幸存法

我们老师刚好说过这个用法：survive作动词时，有两种用法，一种是及物，一种是不及物当它是及物的时候，意思是幸免遇难She survived the attack.当它是不及物动词的时候，意思是存活You need to be tough to survive in the jungle. 要在丛林中活下来就要有坚忍不拔的意志. 你去查一下字典吧，上面写得很清楚

knocked：碰击；被敲的 knocked down：拍板成交 knocked on：被打出的 knocked out 喝醉；神志不清；被麻醉

具体到某一天的前面用on

happy:be happy about(或over)sth...unhappy:be unhappy in sth...但这仅仅是词典上的,事实上happy与unhappy后面加的介词,about或 over或in均可.不信在google上搜一下 be happy in 、be unhappy .about、be unhappy over

happy:be happy about(或over)sth...unhappy:be unhappy in sth...但这仅仅是词典上的,事实上happy与unhappy后面加的介词,about或 over或in均可.不信在google上搜一下 be happy in 、be unhappy .about、be unhappy ...

to.是介词.用doing.一般考试特意考到,尤其是不认识的词组基本都是介词的,出题者惯用手法

seit 后面只能接第三格，这里是形容词化的副词，仍然要按形容词变格，而且是按照中性变。如：am besten = an dem best-en.in Kraft 作表语。

哪国语？

make a telephone call to sb. 给某人打电话eg.: Please make a telephone call to your mom. 请给你的妈妈打个电话。
