Types of Adjusting Entries Events that require adjusting entries essentially relate to the difference between expense and expenditure and between revenue and receipts, discussed in Chapter 3. Four types of such events, together with examples of each, are given below: 调整分录的类型 需要调整分录的的词条事件与区别关系在费用和开支之间和在收支和收据之间, 将在第三章中讨论。这类事件的四种类型，以及每种类型的举例讲在下面介绍。 1. Recorded costs to be apportioned among two or more accounting periods. The fuel oil transaction given above is one example. Another is insurance protection, originally recorded as Prepaid Insurance (an asset) , $800 of which becomes an expense in the current period: 1. 记录的费用被摊分在二个或更多会计年度之中。燃料油交易被给以上是一个例子。另是保险保护, 最初被记录作为被预付的保险(财产), $800 成为费用在当前: Insurance Expense Prepaid Insurance ------------------------------------- ----------------------------------- 800 800 When an asset is reduced, as prepaid insurance was here, it is said that there has been a write-off of part (or all) of the asset. 当财产被减少, 如同被预付的保险这里是, 据说有是部份(或所有的) 注销财产。 2. Unrecorded expenses. These expenses were incurred during the period, but no record of them has yet been made. Example: For $150 of wages earned by an employee during the period but not yet paid to the employee: 2. 未被记录的费用。这些费用被招致了在期间, 但纪录他们未被创造。例子: 为$150 薪水由一名雇员赢得在期间但不被支付对雇员: Wage expense Accrued wages ------------------------------------ ------------------------------------ 150 150 3. Recorded revenues to be apportioned among two or more accounting periods. As was the case with recorded costs, there amounts were initially recorded in one account, and at the end of the accounting period must be properly divided between a revenue account and a liability account. For example, rent collected during the period and recorded as rent revenue, $600 of which is applicable to the next period and hence is a liability at the end of the current period: 记录的收支被摊分在二个或更多会计年度之中。这一点是案件伴随着记录的费用, 数额最初地那里被记录了在一个帐户, 并且在会计年度的结尾必须适当地被划分在收入帐户和负债帐户之间。例如, 租赁收集在期间和记录当租收支, $600 是可适用的对下期间和因此是责任在当前的结尾: Rent Revenue Unearned Rent Revenue ------------------------------------ ------------------------------------ 600 600 4. Unrecorded revenues. These revenues were earned during the period, but no record of them has yet been made. For example, $120 of interest earned by the entity during the period but not yet received: 4. 未被记录的收支。这些收支被赢得了在期间, 但纪录他们未被创造。例如, $120 利益由个体赢得在期间但不被接受: Accrued Interest Receivable Interest Revenue

part of Hypertext Transfer Protocol -- HTTP/1.1RFC 2616 Fielding, et al. 10 Status Code Definitions Each Status-Code is described below, including a description of which method(s) it can follow and any metainformation required in the response. 10.1 Informational 1xx This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. There are no required headers for this class of status code. Since HTTP/1.0 did not define any 1xx status codes, servers MUST NOT send a 1xx response to an HTTP/1.0 client except under experimental conditions. A client MUST be prepared to accept one or more 1xx status responses prior to a regular response, even if the client does not expect a 100 (Continue) status message. Unexpected 1xx status responses MAY be ignored by a user agent. Proxies MUST forward 1xx responses, unless the connection between the proxy and its client has been closed, or unless the proxy itself requested the generation of the 1xx response. (For example, if a proxy adds a "Expect: 100-continue" field when it forwards a request, then it need not forward the corresponding 100 (Continue) response(s).) 10.1.1 100 Continue The client SHOULD continue with its request. This interim response is used to inform the client that the initial part of the request has been received and has not yet been rejected by the server. The client SHOULD continue by sending the remainder of the request or, if the request has already been completed, ignore this response. The server MUST send a final response after the request has been completed. See section 8.2.3 for detailed discussion of the use and handling of this status code. 10.1.2 101 Switching Protocols The server understands and is willing to comply with the client"s request, via the Upgrade message header field (section 14.42), for a change in the application protocol being used on this connection. The server will switch protocols to those defined by the response"s Upgrade header field immediately after the empty line which terminates the 101 response. The protocol SHOULD be switched only when it is advantageous to do so. For example, switching to a newer version of HTTP is advantageous over older versions, and switching to a real-time, synchronous protocol might be advantageous when delivering resources that use such features. 10.2 Successful 2xx This class of status code indicates that the client"s request was successfully received, understood, and accepted. 10.2.1 200 OK The request has succeeded. The information returned with the response is dependent on the method used in the request, for example: GET an entity corresponding to the requested resource is sent in the response; HEAD the entity-header fields corresponding to the requested resource are sent in the response without any message-body; POST an entity describing or containing the result of the action; TRACE an entity containing the request message as received by the end server. 10.2.2 201 Created The request has been fulfilled and resulted in a new resource being created. The newly created resource can be referenced by the URI(s) returned in the entity of the response, with the most specific URI for the resource given by a Location header field. The response SHOULD include an entity containing a list of resource characteristics and location(s) from which the user or user agent can choose the one most appropriate. The entity format is specified by the media type given in the Content-Type header field. The origin server MUST create the resource before returning the 201 status code. If the action cannot be carried out immediately, the server SHOULD respond with 202 (Accepted) response instead. A 201 response MAY contain an ETag response header field indicating the current value of the entity tag for the requested variant just created, see section 14.19. 10.2.3 202 Accepted The request has been accepted for processing, but the processing has not been completed. The request might or might not eventually be acted upon, as it might be disallowed when processing actually takes place. There is no facility for re-sending a status code from an asynchronous operation such as this. The 202 response is intentionally non-committal. Its purpose is to allow a server to accept a request for some other process (perhaps a batch-oriented process that is only run once per day) without requiring that the user agent"s connection to the server persist until the process is completed. The entity returned with this response SHOULD include an indication of the request"s current status and either a pointer to a status monitor or some estimate of when the user can expect the request to be fulfilled. 10.2.4 203 Non-Authoritative Information The returned metainformation in the entity-header is not the definitive set as available from the origin server, but is gathered from a local or a third-party copy. The set presented MAY be a subset or superset of the original version. For example, including local annotation information about the resource might result in a superset of the metainformation known by the origin server. Use of this response code is not required and is only appropriate when the response would otherwise be 200 (OK). 10.2.5 204 No Content The server has fulfilled the request but does not need to return an entity-body, and might want to return updated metainformation. The response MAY include new or updated metainformation in the form of entity-headers, which if present SHOULD be associated with the requested variant. If the client is a user agent, it SHOULD NOT change its document view from that which caused the request to be sent. This response is primarily intended to allow input for actions to take place without causing a change to the user agent"s active document view, although any new or updated metainformation SHOULD be applied to the document currently in the user agent"s active view. The 204 response MUST NOT include a message-body, and thus is always terminated by the first empty line after the header fields. 10.2.6 205 Reset Content The server has fulfilled the request and the user agent SHOULD reset the document view which caused the request to be sent. This response is primarily intended to allow input for actions to take place via user input, followed by a clearing of the form in which the input is given so that the user can easily initiate another input action. The response MUST NOT include an entity. 10.2.7 206 Partial Content The server has fulfilled the partial GET request for the resource. The request MUST have included a Range header field (section 14.35) indicating the desired range, and MAY have included an If-Range header field (section 14.27) to make the request conditional. The response MUST include the following header fields: - Either a Content-Range header field (section 14.16) indicating the range included with this response, or a multipart/byteranges Content-Type including Content-Range fields for each part. If a Content-Length header field is present in the response, its value MUST match the actual number of OCTETs transmitted in the message-body. - Date - ETag and/or Content-Location, if the header would have been sent in a 200 response to the same request - Expires, Cache-Control, and/or Vary, if the field-value might differ from that sent in any previous response for the same variant If the 206 response is the result of an If-Range request that used a strong cache validator (see section 13.3.3), the response SHOULD NOT include other entity-headers. If the response is the result of an If-Range request that used a weak validator, the response MUST NOT include other entity-headers; this prevents inconsistencies between cached entity-bodies and updated headers. Otherwise, the response MUST include all of the entity-headers that would have been returned with a 200 (OK) response to the same request. A cache MUST NOT combine a 206 response with other previously cached content if the ETag or Last-Modified headers do not match exactly, see 13.5.4. A cache that does not support the Range and Content-Range headers MUST NOT cache 206 (Partial) responses. 10.3 Redirection 3xx This class of status code indicates that further action needs to be taken by the user agent in order to fulfill the request. The action required MAY be carried out by the user agent without interaction with the user if and only if the method used in the second request is GET or HEAD. A client SHOULD detect infinite redirection loops, since such loops generate network traffic for each redirection. Note: previous versions of this specification recommended a maximum of five redirections. Content developers should be aware that there might be clients that implement such a fixed limitation.

它似乎比我想象中的还要大。What I have imagine（宾语从句，作宾补）

with a bewildered look on his face是伴随状语修饰前面的句子He turned around.on his face是方位状语表明a bewildered look在哪里。

"with a bewildered look on his face" 中的 with 是介词，表示“有……的”，相当于“带着一副迷惑的表情”。这个短语是形容词短语，在句子中充当伴随状况状语。其中，a bewildered look on his face 是整个形容词短语，指出了他面带的表情。这里的 on his face 是 look 的定语，修饰它的内容，表示是在他的脸上显露出来的表情。整个句子可以理解为：“他转身，脸上带着一副迷惑的表情。”

join,join in和take part in 1)加入某党派、某组织或某社会团体,用join,不可用join in.如：①He will never forget the day when he joined the Party.他永远也忘不了他入党的那一天.②His brother joined the army three years ago.他哥哥是三年前参军的.join还可解释为“连接”.如：①The railway joined the two cities.铁路把两个城市连接起来了.②The two clauses are joined by a conjunction.两个分句由一个连词连接起来.2)说参加某种活动用join in,如说“与其人一起做某事”,则用join sb.in sth./ doing sth..如：①May I join in the game?我可以参加这个游戏吗?②Come and join us in the discussion.来和我们一起讨论吧!③We are having supper now.Would you like to join us?我们正在吃晚饭,你也来和我们一起吃好吗?join in多指参加小规模的活动如“球赛、游戏”等,常用于日常口语.如：①Come along,and join in the ball game.快,来参加球赛.②Why didn"t you join in the talk last night?昨晚你为什么没参加座谈?3)take part in参加(群众性活动、会议等),往往指参加者持积极态度．起一份作用.如：①A great number of students took part in May 4 Movement.大批学生参加了五四运动.②We are going to have an English evening.Do you want to take part?我们准备举办一个英语晚会,你想参加吗?③How many of you are going to take part?你们多少人准备参加?④All the students took an active part in the thorough cleaning.所有的学生都积极参加了大扫除.【注意】take part in是惯用词组,part前一般不用冠词,但part前有形容词修饰时,要用不定冠词.如：Lincoln took an active part in polities and was strongly against slavery.林肯积极参加政治活动,强烈反对奴隶制.enjoy--get pleasure from;take delight in.“享受...之乐趣；乐于”.例如：I"ve enjoyed talking to you about old times.我很高兴曾经和你叙旧.like(vt.vi.)--be fond of;have a taste for; find satisfactory or agreeable.“喜欢；喜爱；爱好” 例如：Do you like fish?你喜欢鱼吗?I like to read in bed but I don"t like having meals in bed.我喜欢躺在床上看书,但我不喜欢在床上吃饭.at the end of“在……末端（尽头）；在……末（底）”可表示时间,也可表示地点.后面可以跟名词或相当于名词的词.在句中作时间状语,可以放在句子开头,也可以放在句子末尾.例如：There is a post office at the end of the road.在路的尽头有一家邮局.At the end of last week,we had a class meeting.到上个星期末,我们开了一次班会.at last=in the end=finally“最后；终于”,后面不接任何单词,在句中作时间状语,一般放在句子开头.例如：At last/Finally,they won the football match.他们终于赢了这场足球比赛.We walked three hours.At last/In the end,we got to the park.我们走了三个小时.最后我们终于到达了公园.及物动词 vt.1.出席,参加He did not attend the meeting yesterday.昨天他没有参加会议.2.上(大学等),前往The school was attended almost entirely by local children.上这个学校读书的几乎全是当地的孩子.3.照料;护理;侍候There was no one to attend him but Tina.除了蒂娜,再无人照顾他了.4.伴随,带有5.陪同,护送不及物动词 vi.1.出席,参加[(+at)]2.照料,处理[(+to)]I"ll attend to the matter.我来处理此事.3.护理;侍候[(+on/upon)]4.注意,倾听;致力(于)[(+to)]She didn"t attend to what I was saying.她并不注意听我所说的话.attend主要用于参加比较重要的场合与会议

首先我们得知道:当手机的重力感应打开的时候, 如果用户旋转手机, 系统会抛发UIDeviceOrientationDidChangeNotification 事件.您可以分别设置Application和UIViewcontroller支持的旋转方向.Application的设置会影响整个App, UIViewcontroller的设置仅仅会影响一个viewController(IOS5和IOS6有所不同,下面会详细解释).当UIKit收到UIDeviceOrientationDidChangeNotification事件的时候, 会根据Application和UIViewcontroller的设置, 如果双方都支持此方向, 则会自动屏幕旋转到这个方向. 更code的表达就是, 会对两个设置求与,得到可以支持的方向. 如果求与之后,没有任何可支持的方向, 则会抛发UIApplicationInvalidInterfaceOrientationException异常.Info.plist设置在App的Info.plist里设置:keyxcode nameSummaryavilable valueUIInterfaceOrientation initial interface orientation Specifies the initial orientation of the app"s user interface. UIInterfaceOrientationPortrait,UIInterfaceOrientationPortraitUpsideDown,UIInterfaceOrientationLandscapeLeft,UIInterfaceOrientationLandscapeRight UISupportedInterfaceOrientations Supported interface orientations Specifies the orientations that the app supports. UIInterfaceOrientationPortrait,UIInterfaceOrientationPortraitUpsideDown,UIInterfaceOrientationLandscapeLeft,UIInterfaceOrientationLandscapeRight 在Info.plist中设置之后,这个app里所有的viewController支持的自动旋转方向都只能是app支持的方向的子集.UIViewControllerIOS6 and abovesupportedInterfaceOrientations在IOS6及以上的版本中, 增添了方法UIViewController.supportedInterfaceOrientations. 此方法返回当前viewController支持的方向. 但是, 只有两种情况下此方法才会生效:当前viewController是window的rootViewController.当前viewController是modal模式的. 即, 此viewController是被调用presentModalViewController而显示出来的.在以上两种情况中,UIViewController.supportedInterfaceOrientations方法会作用于当前viewController和所有childViewController. 以上两种情况之外, UIKit并不会理会你的supportedInterfaceOrientations方法.举个栗子:- (NSUInteger)supportedInterfaceOrientations{ return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft;}如果某个viewController实现了以上方法. 则, 此viewController就支持竖方向和左旋转方向. 此viewController的所有childViewController也同时支持这两个方向, 不多不少.preferredInterfaceOrientationForPresentation此方法也属于UIViewController. 影响当前viewController的初始显示方向. 此方法也仅有在当前viewController是rootViewController或者是modal模式时才生效.shouldAutorotate此方法,用于设置当前viewController是否支持自动旋转. 如果,你需要viewController暂停自动旋转一小会儿. 那么可以通过这个方法来实现.同样的, 此方法也仅有在当前viewController是rootViewController或者是modal模式时才生效.IOS5 and before在IOS5和以前的版本中, 每个viewController都可以指定自己可自动旋转的方向.(这样不是挺好么?苹果那帮工程师为啥要搞成这样...).每当UIkit收到UIDeviceOrientationDidChangeNotification消息的时候, 就会用以下方法询问当前显示的viewController支不支持此方向:- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)orientation{ if ((orientation == UIInterfaceOrientationPortrait) || (orientation == UIInterfaceOrientationLandscapeLeft)) return YES; return NO;}特别要注意的是:你必须至少要对一个方向返回YES.(为难系统总不会有啥好事儿,你懂得).UIView.transform最后一个方法是设置UIView的transform属性来强制旋转. 见下代码://设置statusBar[[UIApplication sharedApplication] setStatusBarOrientation:orientation];//计算旋转角度float arch;if (orientation == UIInterfaceOrientationLandscapeLeft) arch = -M_PI_2;else if (orientation == UIInterfaceOrientationLandscapeRight) arch = M_PI_2;else arch = 0;//对navigationController.view 进行强制旋转self.navigationController.view.transform = CGAffineTransformMakeRotation(arch);self.navigationController.view.bounds = UIInterfaceOrientationIsLandscape(orientation) ? CGRectMake(0, 0, SCREEN_HEIGHT, SCREEN_WIDTH) : initialBounds;需要注意的是:当然我们可以对当前viewController进行旋转, 对任何view旋转都可以.但是, 你会发现navigationBar还横在那里. 所以, 我们最好对一个占满全屏的view进行旋转. 在这里我们旋转的对象是self.navigationController.view, 当然self.window也可以, help yourself~我们需要显式的设置bounds. UIKit并不知道你偷偷摸摸干了这些事情, 所以没法帮你自动设置.如何应付产品经理的需求有了以上三把武器, 我想基本可以应付BT产品经理所有的需求了. 但是这里还有一些小技巧.直接锁死(略)随系统旋转IOS5及之前对于IOS5及之前的版本, 只要在对每个viewController重写shouldAutorotateToInterfaceOrientation方法, 即可方便的控制每个viewController的方向.IOS6及以后对于IOS6及以后的版本, 如果想方便的单独控制每个viewController的方向. 则可以使用这样:对于非modal模式的viewController:如果不是rootViewController,则重写supportedInterfaceOrientations,preferredInterfaceOrientationForPresentation以及shouldAutorotate方法, 按照当前viewController的需要返回响应的值.如果是rootViewController,则如下重写方法:-(NSUInteger)supportedInterfaceOrientations{ return self.topMostViewController.supportedInterfaceOrientations;}-(BOOL)shouldAutorotate{ return [self.topMostViewController shouldAutorotate];}- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{ return [self.topMostViewController preferredInterfaceOrientationForPresentation];}-(UIViewController*)topMostViewController{ //找到当前正在显示的viewController并返回.}显而易见, 我们巧妙的绕开了UIKit只调用rootViewController的方法的规则. 把决定权交给了当前正在显示的viewController.对于modal模式的viewController. 则按照需要重写supportedInterfaceOrientations,preferredInterfaceOrientationForPresentation以及shouldAutorotate方法即可.强制旋转有时候, 需要不随系统旋转, 而是强制旋转到某一个角度. 最典型的场景就是视频播放器, 当点击了全屏按钮的时候, 需要横过来显示.对于IOS5及以前的版本, 可以用下面的方法:if ([[UIDevice currentDevice] respondsToSelector:@selector(setOrientation:)]) { SEL selector = NSSelectorFromString(@"setOrientation:"); NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:[UIDevice instanceMethodSignatureForSelector:selector]]; [invocation setSelector:selector]; [invocation setTarget:[UIDevice currentDevice]]; int val = UIInterfaceOrientationLandscapeRight; [invocation setArgument:&val atIndex:2]; [invocation invoke];}对于IOS6及以后的版本. UIDevice.setOrientation从隐藏变为移除.只能通过设置UIView.transform的方法来实现.

Happens是happen的第三人称单数形式 Happened是happen的过去式

"whateverhappened,happened"isthe11thtelevisionepisodeofthefifthseasonofabc"slost.大概意思就是已经发生的事情已经不能改变了你的前一句我不确信有这种说法如果是whathappenedhappens那的确有不同的意思

区别如下：1、意思what happens，如：Do you want to know what happens every day?意即“你想知道每天发生什么事吗?”what happened，如：Can you tell me what happened yesterday/just now？意即“你能告诉我昨天/刚才发生什么事了吗?”。2、时态what happens这种表达就是表示一般现在时；what happened 表示过去时。3、用法：what看作第三人称单数形式。句子是一般现在时，那么happen要加s，如果是一般过去时就要加ed。扩展资料what happens表示一般现在时,比如：Do you want to know what happens every day?意即“你想知道每天发生什么事吗?” ,what happened表示过去时,当然还有what has / had happened,分别表示一般完成时和过去完成时,根据具体语境来决定.还有就是happen 没有被动时,这点要注意.如果表示过去发生了什么,就是what happened,比如：Can you tell me what happened yesterday/just now?意即“你能告诉我昨天/刚才发生什么事了吗?”除此以外,我们还可以说what has happened或者写成what"s happened（一定要注意不是what is happened）,表示已经发生了什么事,比如：Do you know what has happened so far?

原型是happen。现在分词happening，过去式happened，过去分词happened，第三人称单数happens，所以happend的原型为happen。

[思路分析] 1.发生 The accident happened outside my house. 这个事故发生在我家房子的外面. 2.（与to连用）碰巧,巧遇 I happened to be in the market yesterday when a fire started. 昨天发生火灾时,我正好在市场上. I happened to see Peter on the way to the bookstore yesterday. 昨天我去书店的路上碰巧遇见了彼得. 3.（与on,upon连用）偶然发现 I happened on an old country hotel during the last summer holidays. 去年暑假期间我偶然发现了一家古老的乡村旅馆. 4.happen　to．．．临到某人头上 Did you hear what happened to David last night? 你听说大卫昨天晚上发生什么事了吗? [解题过程] 以上四种是比较常见的用法,尤其是前两种一定要记住 近意词有：occur,take place都是发生的意思

sb have happened with sth 某人发生某事sb have happened to sth 某人碰巧做某事 （遇见老同学之类的）

happen:动词原形 happens:happen的第三人称单数形式 happened:happen的过去式和过去分词

happened后用什么介词取决于后面的词：1、happened to + 人；2、happened at + 地点，时间（几点）；3、happened in + 年

happened with：About what happened with us.我们之间的事Things finally happened with Kate.我跟凯特终于有进展了happened to：发生于；偶然发生Let me tell you what happened to me once.让我告诉你曾经发生在我身上的事。

发生的

“发生”的过去式

帮助。

happen。根据基本英语语法可以得知，happened的原形形式是happen，原形是一个动词，意思是发生。happened是happen的过去式形态，意思是过去发生的，happening是happen的现在分词形式，意思是现在正在发生的。

1、happen:“发生”,动词原形. 2、happens:“发生”；一般会说“It always happens in the night”. 3、happened:“发生过了,发生了”,是过去式；例如“Many accidents happened last year.”

happen是个不及物动词，所以没有被动时态happened是指一个事情已经发生的状态 be happened可以指某事发生了

过去式，表示已经发生的事情

1、意思what happens，如：Do you want to know what happens every day?意即“你想知道每天发生什么事吗?”what happened，如：Can you tell me what happened yesterday/just now？意即“你能告诉我昨天/刚才发生什么事了吗?”。2、时态what happens这种表达就是表示一般现在时；what happened 表示过去时。3、用法：what看作第三人称单数形式。句子是一般现在时，那么happen要加s，如果是一般过去时就要加ed。扩展资料what happens表示一般现在时,比如：Do you want to know what happens every day?意即“你想知道每天发生什么事吗?” ,what happened表示过去时,当然还有what has / had happened,分别表示一般完成时和过去完成时,根据具体语境来决定.还有就是happen 没有被动时,这点要注意.如果表示过去发生了什么,就是what happened,比如：Can you tell me what happened yesterday/just now?意即“你能告诉我昨天/刚才发生什么事了吗?”除此以外,我们还可以说what has happened或者写成what"s happened（一定要注意不是what is happened）,表示已经发生了什么事,比如：Do you know what has happened so far?

what happened意思是：发生了什么事。

happened 是发生的意思

意思为发生了什么whathappened是一般过去时，强调动作发生在过去，但与现在无关。whathashappened？是现在完成时，动作也发生在过去，但对现在还有影响或结果，也就是说结果仍然存在。不知你明白了吗？比如路上发生事故，你看热闹问：whathappened？注重事件性。而后者是比如你朋友出事故了，你上前去问他：whathashappened？注重过程性。

口语是见不到标点符号的。所以若只是口语，两者字面上不会有任何区别，区别只在语气中。然而，若这两个句子是用书面语言表达的口语，如小说中对口语的描述，两者则有语气上的些微区别。因为多了一个逗号说明说话时有非常短小的停顿。仅供参考再看看别人怎么说的。

偶然发生，碰巧；happen的过去式
