有时候你可能与某个人有着很亲密的关系，比如一个企业主管、一个名人、一教授或者比你自己年长的人。别人都称呼他/她为Sir/Madam,
Mr/Mrs，而在某种程度上这个人可能会允许你直接叫他/她的名字。英语里我们就用"on
a
first
name
basis"或者"on
first
name
terms"来表达这样一段并不像人们所以为的那么拘于礼节的关系。来看两个例句：Pete's
mom
and
I
are
on
a
first
name
basis.
皮特的妈妈和我是直呼其名的好朋友。

不规则动词过去式和过去分词巧记方法

一、原形、过去式和过去分词的词形和读音都相同的单词，结尾字母一般是t或d。如：

cut-cut-cut, hit-hit-hit, put-put-put, cost-cost-cost, let-let-let, shut-shut-shut, set-set-set, hurt-hurt-hurt, spread-spread-spread

特殊：动词read的过去式和过去分词虽然词形与原形一致，read-read-read，但发音分别是[ri:d]-[red]-[red]。

二、有些动词的过去分词与原形是一样的。如：

come-came-come, become-became-become, run-ran-run, overcome-overcame-overcome

三、有些动词的过去式和过去分词相同。如：

1. 把单词结尾的字母d改为t。如：

lend-lent-lent, spend-spent-spent, send-sent-sent

2. 改变单词中间元音字母。如：

sit-sat-sat, win-won-won, shine-shone-shone, hold-held-held

3. 以eep结尾的动词，把eep改为ept。如：

keep-kept-kept, sleep-slept-slept, sweep-swept-swept

4. 过去式和过去分词都以augh或ough结尾的动词。如：

buy-bought-bought, fight-fought-fought, think-thought-thought, bring-brought-brought, teach-taught-taught, catch-caught-caught

5. 有的以ay结尾的动词，在过去式和过去分词中把ay变成aid。如：

say-said-said, lay-laid-laid, pay-paid-paid

6. 另有一些其它形式的变化。如：

have-had-had, learn-learnt-learnt, leave-left-left, lose-lost-lost, make-made-made, meet-met-met, feel-felt-felt

四、有些动词原形中含有字母i，在过去式中变i为a，在过去分词中变i为u。如：

begin-began-begun, sing-sang-sung

五、以字母ow或aw结尾的动词，在变成过去式时，通常把元音字母变成e，在变成过去分词时，通常只在词尾加n。如：

blow- blew- blown, draw-drew-drawn, grow-grew-grown, throw-threw-thrown, know-knew-known

六、有些动词的过去分词是在原形词尾加n或en，变成以en结尾的单词。如：

Rise-rose-risen, arise-arose-arisen， give-gave-given, take-took-taken, fall-fell-fallen, drive-drove-driven, eat-ate -eaten

特殊： write-wrote-written, speak-spoke-spoken, ride-rode-ridden, get-got-gotten

Ⅶ 英语中的非重读音节

1、非重读音节，首先可以看音标，重读音节前面都有'，反之没有'的就是非重读音节。

2、非重读基本上说是将几个元音字母读成er或者是i音。

如：way方法、stay停留、play游戏、fly飞、clay黏土

一、way

读音：英 [weɪ] 美 [weɪ]

例句：

.

电子订票系统通过多种方式帮助航空公司获利。

二、stay

读音：英 [steɪ] 美 [steɪ]

例句：

GordonstayedatTheParkHotel,Milan.

戈登下榻在米兰的帕克饭店。

三、play

读音：英 [pleɪ] 美 [pleɪ]

例句：

Whilethetwinsplayedcards,Francissatreading.

那对双胞胎玩扑克牌的时候，弗朗西斯坐着看书。

四、fly

读音：英 [flaɪ] 美 [flaɪ]

例句：

.

周四可能会将妇女和儿童空运出去。

五、clay

读音：英 [kleɪ] 美 [kleɪ]

例句：

,.

多数网球比赛在硬地球场上举行，不过也有相当数量的比赛在红土球场上进行。

Ⅷ 非负数整数英语单词怎么写

整数：Z
自然数：Q
实数：R
正整数：Z+（+号在Z的肩上）
负整数：Z-（-号在Z的肩上）
应该都是缩写

Ⅸ 非谓语动词 英文怎么说

动词不定式、分词(现在分词，过去分词)和动名词统称为非谓语动词。现代英语将现在分词和动名词合为一大类叫作v
+
ing形式。这些动词的形式不能在句中单独作谓语用，因而没有语法主语。但可以有逻辑主语。由于没有语法主语，也就不受人称和数的限定，因为不是谓语，也就没有时态和语态，但这些词仍能表示动作和状态，所以仍有表示与其他动词相对时间关系的形式。由于与其它词有逻辑上的主谓关系，因此也有表示主、被动的形式，同时也有自己的宾语和状语，一起构成非谓语动词的短语(动词不定式短语，分词短语，动名词短语)。非谓语动词在英语语法中占有特殊且重要的位置。非谓语动词形式多样，应用广泛，且在句中起着很活跃的作用，也是语法项目中的重点和难点，学好非谓语动词，才能正确进行口语和书面的交流。

动词不定式、过去分词及v-ing形式在句中均不能作谓语用，所以叫做非谓语动词。

（一）动词不定式：
动词不定式由“to+
动词原形”构成，如：to
study,
to
play，动词不定式虽然不能作谓语动词用，但仍留着动词的特征，它可以带有所需要的宾语或状语而构成动词不定式短语，如：to
study
hard,
to
play
table
tennis。

1、动词不定式的形式变化：动词不定式有下列时态和语态的形式变化。
语态式
一般式
完成式
进行式

完成进行式
主
动
to
build
to
have
built
to
be
building
to
have
been
building
被
动
to
be
build
to
have
been
build

2、动词不定式的基本用法：动词不定式能起名词、形容词和副词的作用，可在句中作主语、表语、宾语补足语、定语和状语用，如：

（1）作主语：to
help
each
other
is
good.（动词不定式作主语时，一般可用it作形式主语，而将作主语的动词不定式置于句末，如：it
is
good
to
help
each
other.

（2）作表语：my
job
is
to
drive
them
to
the
power
station
every
day.
动词不定式在系动词be之后作表语，与表示将来时的be
+
动词不定式结构有所区别，如：our
plan
is
to
set
up
another
middle
school
for
the
peasants’
children.我们的计划是给农民子弟再成立一所中学。（句中的谓语动词为is，动词不定式to
set
up…
为表语，主语为plan，但plan并不是动词不定式的逻辑主语，即动词不定式
to
set
up所表示的动作不是主语plan产生的。）we
are
to
set
up
another
middle
school
for
the
peasants’
children.我们将为农民的子弟再成立一所中学。（句中的are
to
set
up整个结构为句中谓语，主语为we，同时也是动词不定式to
set
up所表示的动作的逻辑主语，即动词不定式to
set
up所表示的动作是由we产生的）。
