wear/dress/put on/in/with的区别

put on,动词短语着重于“穿”这一动作,即由没穿到穿这一动作的完成,意为“穿上、戴上””后接衣服、鞋帽等。例如:

I want you to put on this coat and this hat.

我要你穿这件外套,戴这顶帽子。

Put on your heavy winter coat if you are going out.

如果你要出去,穿上你的厚冬衣。

wear 动词,“穿着;戴着”,表示状态,宾语可以是衣帽,也可以是饰物、奖章等。而dress, put on 一般不这样用。如:

He seldom wears a watch. 他很少戴表。

He wears red T-shirt today.

You’d better wear blue or bla ck pants with blown shoes.

穿棕色鞋子的时候, 最好要穿蓝色或黑色裤子。

Why does he often wear dark sunglasses? 他为什么经常戴着深色的太阳镜?

He was wearing a new jacket. 他当时穿着一件新夹克。

Such clothes are not often worn nowadays. 现在那样的衣服很少有人穿了。

dress 动词,常用人作宾语,不接“衣”作宾语,意为“给……穿衣服”。在表示“自己穿衣”时可说get dressed (= dress oneself)。当dress表示状态时,一般要用be dressed in形式。dress up强调着意打扮,意为“穿上盛装、乔装打扮”。例如:

My son is now able to dress himself. 我儿子现在自己会穿衣服了。

It’s time to wake up and get dressed! 该起床穿衣服了。

She is dressed in a fur coat. 她穿着毛皮大衣。

She always dresses well. 她总是打扮得很漂亮

注:dress 还通常用于被动语态。如:

The girl was poorly dressed. 这女孩衣着寒酸。

in是介词,表示“穿着、戴着”之意,后接表示衣服或颜色的词,着重于服装的款式或颜色。

它所构成的短语只能作表语或定语。

He was in a new black coat. 他穿着黑色的新外套。

The girl in red is my sister. 那个穿红衣服的女孩是我妹妹。

编校一课丨连接号用法大全

编校一课丨连接号用法大全 《标点符号用法》新标准中,连接号删除长横线“——”,只保留三种形式:一字线“—”、半字线“-”、波纹线“~”。三种连接号的使用范围各不相同。一字线 一字线占一个字位置,比汉字“一”略长标示时间、地域等相 关项目间的起止或相关项之间递进式发展时使用一字线。例:1.沈括(1031—1095),宋朝人。 2.秦皇岛—沈阳将建成铁路客运专线。 3.人类的发展可以分为古猿—猿人—古人—新人这四个阶段半字线半字线也叫短横线,比汉字“一”略短,占半个字位置。用于产品型号、化合物名称、 代码及其他相关项目间的连接。例:1.铜-铁合金(化合物 名称) 2.见下图3-4(表格、插图编号) 3. 中关园3号院3-2-11室(门牌号) 4.010-********(电话号码) 5.1949-10-01(用阿拉伯数字表示年月日) 6.伏尔加河-顿河运河(复合名词)波纹线波纹线俗称波浪线,占一个字位置标示数值范围的起止时用波纹线,包括用阿拉伯数字表示的数值和由汉字数字构成的数值。例:1.10~30cm 2. 第七~九课常见问题1.在数值间使用连接号时,前后两个数值都需要加上计量单位吗?在标示数值范围时,用波纹线连接号。此时,在不引起歧义的情况下,只在后一数值后计量单位,用波纹线连接的两个

数值,其单位是一致的。例:500~1000公斤 2.“1996~现在”这样的用法对吗?不对。波纹线连接数字,“现在”不是数字,应改为“”到或“至”。“1996”后宜加“年”。 关注“木铎书声”,做优秀出版人木铎书声是北京师范大学出版科学研究院官方微信平台,致力于传播最新行业动态,促进出版职业人的发展。

He was waiting for the bus. 他在等公共汽车。 【用法说明】在通常情况下,英语不用for doing sth 来表示目的。如: 他去那儿看他叔叔。 误:He went there for seeing his uncle. 正:He went there to see his uncle. 但是,若一个动名词已名词化,则可与for 连用表目的。如: He went there for swimming. 他去那儿游泳。(swimming 已名词化) 注意:若不是表目的,而是表原因、用途等,则其后可接动名词。(见下面的有关用法) 用法2:(表利益)为,为了。如: What can I do for you? 你想要我什么?

连接号(一字线、浪纹线等)用法

连接号(一字线、浪纹线等)的用法 国家标准《标点符号用法》(GB/T15834—1995)把连接号分为一字线(—)、半字线(-)、浪纹线(~)和长横线(——)4种形式。 一、各种形式连接号的使用场合 1.一字线的使用场合 一字线主要用于表示走向、起止和递进关系。有“至”(到)的意思。 深圳—重庆—拉萨航线。2000—2006年;2007年1—5月;2008年3月5—17日;上午8:OO—12:OO。第1—13卷。4—6年级;10—15行;35—37页。计算机经历了电子管计算机—晶体管计算机—集成电路计算机—大规模、超大规模集成电路计算机4个发展阶段。 2.半字线的使用场合 半字线用来连接成词组或代号,仅是前后两者之间的一种间隔。 焦耳-楞次定律。总产量-平均产量-边际产量曲线图。图2-11;表3-5;式(5-13)。型号:SDY-1A;DW-5725B-7D。ISBN928-7-5624-3868-6;ISSN 1003-6687;CN 11-00790。)1949-10-01。 3.浪纹线的使用场合 浪纹线只有一种用法,就是用于具有统计意义的2个数字之间,表示数值(量值)的起止范围。 硬盘容量为1~100 GB。8%~9%,800万~900万个。-12~-3℃;80~100m /s;100~120 MPa;3~5g/mL。 4.长横线的使用场合 长横线与破折号的用法基本一致。 二、常见错误用法 1.一字线和浪纹线的混用 一字线和浪纹线都有“至”的意思,但两者有很明显的区别。浪纹线连接的前后两个数字,一要阿拉伯数字,二要有统计意义。无统计意义的阿拉伯数字之间,具有“至”的意思的,都用一字线。 2.一字线和半字线的混用

现在进行时动词加ing的变化规律 1)一般情况下,直接加 -ing: 如:go—going answer—answering study—studying be—being see—seeing [注一] 和名词复数、一般现在时动词第三人称单数加-s(-es)不同, 动词末尾如为“辅音字母 + y”时,y不变,其后直接加ing。 如: study—studying fly—flying carry—carrying [注二] 动词结尾为辅音字母r时,加-ing,r在此必须发音。 如: water—watering answer—answering wear—wearing 2)以不发音的e结尾的动词,去掉e,再加ing 如:come—coming write—writing take—taking become—becoming 3)动词是闭音节的单音节词,或是以重读闭音节结尾的多音节词, 而末尾只有一个辅音字母时,这个辅音字母须双写,然后再加ing。 如:sit—sitting run—running stop—stopping begin—beginning admit—admitting forget—forgetting [注一] send,think,accept等动词虽是闭音节或以重读闭音节结尾, 但末尾有一个以上的辅音字母,因此,这个辅音字母不双写,应直接加ing。 如:sending thinking accepting 4)少数几个以-ie结尾的动词,须将ie变作y,再加ing。 如:die—dying tie—tying lie—lying躺,说谎 5)少数以-c结尾的动词变为现在分词时和过去式,须先将-c变为ck,然后再加-ing 或-ed 。 如:picnic—picnicking (picnicked) traffic—trafficking (trafficked)

连字符使用的基本规则

连字符使用的基本规则有: 一、连字符可用于构成复合词。这种复合词主要有: 1.形容词+名词: 如long-distance telephone(长途电话),old-style machine(旧式机器)。 2.名词+v-ing: 如peace-loving people(热爱和平的人民)。 3.名词+过去分词: 如hand-made goods(手工制品),man-made lake(人工湖泊)。 4.副词+过去分词: 如high- ly-developed industry(高度发达的工业)。 5.副词+v-ing: 如hard-working people勤劳的人民。 6.名词+名词: 如coal-mine(煤矿),wave-length(波长)。 7.形容词+名词-ed: 如old-fashioned machine(老式机器),cold-blooded animals(冷血动物) 8.名词+形容词: 如snow-white paper(雪白的纸)。 9.形容词+v-ing(或过去分词): 如funny-looking man(相貌可笑的人),clear-cut answer(明确的回答)。 10.形容词+形容词: 如dark-blue ink(深蓝色的墨水)。 二、连字符常被用于作为定语的一个单元修饰语之间,以避免误解。 如:Mr Green was a small-business man.格林先生是位做小买卖的商人。 Mr Green was a small business man.格林先生是一个身材矮小的商人。 三、位于名词之前用作定语的复合修饰语之间,一般应加连字符。 如:Jim is a 15-year-old boy.吉姆是一个十五岁的男孩。 Lily is a well-dressed woman.莉莉是一个衣着漂亮的女人。 四、通常在self-,ex-,half-,quarter-,all-作为词缀的复合词各部分之间应加连字符。如:self-control(自制),self-respect(自尊心),ex-president(前总统),half-aslee p(半睡的),quarter-share(四分之一部分),all-round(多才多艺的)。 五、连字符可用来连接由一个单一的大写字母和一个名词或分词构成的复合词。 如:an X-ray photograph(一张X光照片)V-shaped thing(V形物)。 六、连字符可用来连接21—99的复合数词。 如:thirty-nine(39),fifty-one(51),eighty-eight(88) 七、连字符可用在书写分数的分子和分母之间,特别是在当这一分数用作修饰语时。 如:a three-fourths majority(占四分之三的大多数)。 八、当连字符用在数词之间或日期时,它有“到”和“包括”的含义。 如:pages 12-56(从第十二页到第五十六页)。 九、连字符可用于某些前缀分词与词根之间。 如:vice-chairman(副主席)。 十、连字符可用于临时性的复合词的单词之间。 如:good-for-nothing material

(3)现在进行时表示感情色彩: 现在进行时有时可表示满意、称赞、惊讶、厌恶等感情色彩,通常与always,forever,constantly,continually等副词连用。比较: She’s always helping people. 她老是帮助别人。(表赞扬) She always helps others. 他总是帮助别人。(陈述一个事实) The boy is constantly lying. 这孩子老是撒谎。(表示厌恶) The boy often lies. 这孩子常撒谎。(指出缺点) 二、结构: 现在进行时常有三种句型: (1)肯定式:主语+be+v-ing+其它。 如:He is mending his bike.他正在修自行车。 (2)否定式:主语+be+not+v-ing+其它。 如:He is not(isn't)mending his bike.他没在修自行车。 (3)疑问式:主要分一般疑问句和特殊疑问句两种句式。 一般疑问句:Be+主语+v-ing+其它? 如:—Is he mending his bike?他正在修自行车吗?—Yes,he is.(No,he isn't.)特殊疑问句:疑问词+be+主语+v-ing+其它? 如:—What is he doing?他正在干什么? 三、何时用现在进行时? (1)以Look!或Listen!开头的句子提示我们说话时动作正在进行,应用现在进行时。 如:Look!The children are playing games over there. Listen!Who's singing in the classroom? (2)当句子中有now(现在)时,常表示说话时动作正在进行,这时也常用现在进行时。 如:We are reading English now. (3)描述图片中的人物的动作时常用现在进行时,以示生动。 如:Look at the picture.The girl is swimming.
