形容词的概念：
形容词(adjective)，简称adj.或a，形容词用来修饰名词或代词，表示人或事物的性质、状态，和特征的程度好坏与否，形容词在句中作定语、表语、宾语补足语。通常，可将形容词分成性质形容词和叙述形容词两类，其位置不一定都放在名词前面。 形容词的作用与位置：
形容词是用来修饰名词的，常被放在名词前作定语，或放在系动词后面作表语。以下属几种特殊情况，须牢记；（1）形容词短语作定语，定语后置。如：a language difficult to master,&&&&&&& a leaning tower about 180 feet high（2）表语形容词（afraid、alike、alone、asleep、awake、alive等）作定语，定语后置。如a man alive。有些表身体健康状况的形容词如well、faint、ill只作表语。sick既可作表语又可作定语，ill如作定语意为“bad”。（3）用作定语，修饰由不定代词one、no、any、some和every构成的复合词如anything、something等时，通常后置。如：I have something important to tell you.（4）else常用作疑问代词和不定代词的后置定语。（5）enough、nearby修饰名词前置或后置，程度副词一般位于形容词、副词前面，enough修饰形容词、副词时，必须后置。（6）几个并列的形容词作定语，其语序通常为：限定语（The、A）+描绘性形容词+size（大小）+shape（形状）+age（年龄、时间）+color（颜色）+origin（国籍、来源）+material（材料）+purpose（目的）+名词。口诀：限定描绘大长高，形状年龄和新老；颜色国籍跟材料，作用类别往后靠。 如：a heavy black Chinese steel umbrella, &&&&&&& the man's first tow interesting little red French oil paintings形容词的用法：
1、形容词修饰名词，说明事物或人的性质或特征。通常，可将形容词分成性质形容词和叙述形容词两类，其位置不一定都放在名词前面： 1）直接说明事物的性质或特征的形容词是性质形容词，它有级的变化，可以用程度副词修饰，在句中可作定语、表语和补语。例如：hot热的。 2）叙述形容词只能作表语，所以又称为表语形容词。这类形容词没有级的变化，也不可用程度副词修饰。大多数以a开头的形容词都属于这一类。例如：afraid害怕的。（错）Heisanillman. （对）Themanisill. （错）Sheisanafraidgirl. （对）Thegirlisafraid. 这类词还有：well，unwell，ill，faint，afraid，alike，alive，alone，asleep，awake等。 3）形容词作定语修饰名词时，要放在名词的前边。但是如果形容词修饰以-thing为字尾的词语时，要放在这些词之后。例如：somethingnice 2、用形容词表示类别和整体： 1）某些形容词加上定冠词可以泛指一类人，与谓语动词的复数连接。如：the dead，the living，the rich，the poor，the blind，the hungry The poorarelosinghope.穷人失去了希望。 2）有关国家和民族的形容词加上定冠词指这个民族的整体，与动词的复数连用。如：the British，the English，the French，the Chinese. The English have wonderful senseofhumor.
以-ly结尾的形容词： 1）大部分形容词加-ly可构成副词。但friendly，deadly，lovely，lonely，likely，lively，ugly，brotherly，仍为形容词。改错：如：（错）She sang lovely. &&&&&&& （错）He spoke to me very friendly. &&&&&&& （对）Her singing was lovely. &&&&&&& （对）He spoke to me in a very friendly way.2）有些以-ly结尾既为形容词，也为副词。 daily，weekly，monthly，yearly，early .如：The Times is a daily paper.&&&&&&&&&The Times is published daily. 形容词知识体系：
&复合形容词的构成：
（1）形容词+名词+ed：&&&&&&&&& 如：kind-hearted 好心的，white-haired 白发的（2）形容词+形容词：&&&&&&&&& 如：red-hot 炽热的，dark-blue 深蓝的（3）形容词+现在分词：&&&&&&&&& 如：good-looking 好看的，easy-going 随和的（4）副词+现在分词：&&&&&&&&& 如：hard-working 勤劳的，fast-moving 快速转动的（5）副词+过去分词：&&&&&&&&& 如：hard-won 得来不易的，newly-made 新建的（6）名词+形容词：&&&&&&&&& 如：life-long 终生的，world-famous 世界闻名的（7）名词+现在分词：&&&&&&&&& 如：peace-loving 爱好和平的，fun-loving 爱开玩笑的（8）名词+过去分词：&&&&&&&&& 如：snow-covered 白雪覆盖的，hand-made 手工的（9）数词+名词+ed：&&&&&&&&& 如：four-storeyed 4层楼的，three-legged 3条腿的（10）数词+名词（名词用单数）：&&&&&&&&& 如：ten-year 10年的,& two-man 两人的

What is epoch time?
The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO -01-01T00:00:00Z).
Literally speaking the epoch is Unix time 0 (midnight 1/1/1970), but 'epoch' is often used as a synonym for 'Unix time'.
Many Unix systems store epoch dates as a signed 32-bit integer, which might cause problems on January 19, 2038 (known as the Year 2038 problem or Y2038).
How to get the current epoch time in ...
Pythonimport time first, then time.time()
RubyTime.now (or Time.new). To display the epoch: Time.now.to_i
Javalong epoch = System.currentTimeMillis()/1000;
C#var epoch = (DateTime.UtcNow - new DateTime()).TotalS
Objective-C[[NSDate date] timeIntervalSince1970]; (returns double) or NSString *currentTimestamp = [NSString stringWithFormat:@"%f", [[NSDate date] timeIntervalSince1970]];
C++11double now = std::chrono::duration_cast&std::chrono::milliseconds&(std::chrono::system_clock::now().time_since_epoch()).count();
VBScript/ASPDateDiff("s", "01/01/:00", Now())
AutoIT_DateDiff('s', " 00:00:00", _NowCalc())
DelphiEpoch := DateTimetoUnix(Now); Tested in Delphi 2010.

JavaScriptMath.round(new Date().getTime()/1000.0) getTime() returns time in milliseconds.

Convert from human readable date to epoch
PHPstrtotime("15 November 2012") (converts most English date texts) or:date_create('01/15/2010')->format('U') (PHP5 DateTime class)

RubyTime.local(year, month, day, hour, minute, second, usec ) (or Time.gm for GMT/UTC input). To display add .to_i
PerlUse the
Javalong epoch = new java.text.SimpleDateFormat("MM/dd/yyyy HH:mm:ss").parse("01/01/:00").getTime() / 1000;
VBScript/ASPDateDiff("s", "01/01/:00", time field)

JavaScriptUse the
Unix/Linux Shelldate +%s -d"Jan 1, :01" Replace '-d' with '-ud' to input in GMT/UTC time.
Convert from epoch to human readable date
PHPdate(output format, epoch); Output format example: 'r' = RFC 2822 date
Pythonimport time first, then time.strftime("%a, %d %b %Y %H:%M:%S +0000", time.localtime(epoch))
Replace time.localtime with time.gmtime for GMT time.
RubyTime.at(epoch)
C#private string epoch2string(int epoch) {
return new DateTime(, 0, 0, 0, DateTimeKind.Utc).AddSeconds(epoch).ToShortDateString(); }
PerlUse the
JavaString date = new java.text.SimpleDateFormat("MM/dd/yyyy HH:mm:ss").format(new java.util.Date (epoch*1000));
VBScript/ASPDateAdd("s", epoch, "01/01/:00")
AutoIT_DateAdd("s", $EpochSeconds , " 00:00:00")
DelphimyString := DateTimeToStr(UnixToDateTime(Epoch)); Where Epoch is a signed integer.
Objective-CNSDate * myDate = [NSDate dateWithTimeIntervalSince1970:epoch]; NSLog(@"%@", date);
Ras.POSIXct(epoch, origin="", tz="GMT")
MySQLFROM_UNIXTIME(epoch, optional output format) Default output format is YYY-MM-DD HH:MM:SS. If you need support for negative timestamps: DATE_FORMAT(DATE_ADD(FROM_UNIXTIME(0), interval - second),"%Y-%m-%d") (replace - with epoch)
PostgreSQLPostgreSQL version 8.1 and higher: SELECT to_timestamp(epoch);
Older versions: SELECT TIMESTAMP WITH TIME ZONE 'epoch' + epoch * INTERVAL '1 second';
SQLiteSELECT datetime(epoch_to_convert, 'unixepoch'); or local timezone: SELECT datetime(epoch_to_convert, 'unixepoch', 'localtime');
Oracle PL/SQLSELECT to_date('01-JAN-1970','dd-mon-yyyy')+(/60/60/24) from dualReplace
with epoch.
SQL Server DATEADD(s, epoch, ' 00:00:00')
Microsoft Excel =(A1 / 86400) + 25569 Format the result cell for date/time, the result will be in GMT time (A1 is the cell with the epoch number). For other time zones: =((A1 +/- ) / 86400) + 25569.
Crystal Reports DateAdd("s", {EpochTimeStampField}-14400, #1/1/:00#) -14400 used for Eastern Standard Time. See .
JavaScriptUse the
Tcl/Tkclock format
Unix/Linux Shelldate -d @ Replace
with your epoch, needs recent version of 'date'. Replace '-d' with '-ud' for GMT/UTC time.
PowerShellFunction get-epochDate ($epochDate)
{ [timezone]::CurrentTimeZone.ToLocalTime(([datetime]'1/1/1970').AddSeconds($epochDate)) }, then use: get-epochDate . Works for Windows PowerShell v1 and v2
Other OS'sCommand line: perl -e "print scalar(localtime(epoch))" (If Perl is installed) Replace 'localtime' with 'gmtime' for GMT/UTC time.
