一种语言的词汇绝不能看作是无生命的、完全的整体。词汇是会通过其构词能力不断地生成和再生成的。
Cmpunding（合成）
Cnversin（转化）
Derivatin（派生）
Abbreviatin（缩略）
1. 合成法(cmpunding)：把两个或更多的词合成一个新词，可用连字符连接，也可直接写一起，或者由分开的两个词构成。合成词一般包括：合成名词、合成形容词、合成动词等。
构词法 (Wrd frmatin)
1) 合成名词名词+名词：pstman邮递员, ntebk笔记本形容词+名词：blackbard黑板, supermarket超市名词+动词： sunrise日出, haircut理发，发型动词-ing形式+名词：reading rm阅览室, washing machine洗衣机名词+动词-ing形式：handwriting书写, papermaking剪纸动词+名词：pickpcket扒手, wrkrm工作室动词+副词：breakup分裂，瓦解其它形式：get-tgether聚会, g-between媒人, passer-by路人
2) 合成形容词形容词+名词+ed: warm-hearted热心的形容词+v.-ing: gd-lking好看的 副词+v.-ing: hard-wrking努力工作的 名词+v.-ing: English-speaking 说英语的名词+v.-ed: man-made人造的 副词+v.-ed: well-knwn 著名的形容词+名词: mid-east中东的, rund-trip往返的
3) 合成代词代词宾格/物主代词+ self / selves：herself, urselves某些不定代词sme, any, every, n等+ bdy /ne / thing：anyne, nthing4) 合成介词介词+副词：within在..之内副词+名词：utside在外面

Find the Cmpunding wrds in the reading material and give the meanings.
While we’re ding all this travelling, we can get seasick at sea, airsick in the air and carsick in a car, but we dn’t get hmesick when we get back hme. And speaking f hme, why aren’t hmewrk and husewrk the same thing?
seasick（晕船）; airsick（晕机）; carsick（晕车）; hmesick（想家）; hmewrk（家庭作业）; husewrk（家务事）
2. 派生法(Derivatin)：在一个词根之前或之后加上一个词缀，构成一个新词，这种构词法叫派生法。单词前加前缀，一般不改变词性，只引起意义上的变化。单词后加后缀，一般意义变化不大，只改变了词性。如：(dis)agree, agree(ment), （dis）agree(ment)。
① They als shared with us many __________ (traditin) stries abut Hawaii that were ________(huge) ppular with turists.② We are s prud f her. It's ____________ (wnder).③All the ftball _________(play) n the playgrund cheered ludly.
1. 按所给词的正确形式填空
rain(形容词) ________ agree(反义)__________ natin(形容词)_______ farm(人)__________ recent(副词)________ friend(形容词)________ hpe(形容词)_______ jb(否定形容词)_________ visit(名词)__________ access(形容词) ________ eight(八十)________ true(名词)___________ kind(名词)_______ China(形容词)________
2. 按括号内的要求改写下列单词
hpeful/hpeless
3. 转化法(Cnversin)：有些名词可作动词，有些形容词可作动词、名词或副词。这种保持词形不变，但改变词性的方法叫转化法。
1) 动词转化为名词 有些词在转化过程中词义变化不大，如attempt试图, laugh大笑。有些动词转化为名词时意义有一定的变化，如： wind (v. 上发条→n.风） tear（v. 撕开→ n. 泪水）， recrd（v. 记载，录制→ n. 记录）。
2) 名词转化为动词face n. 脸→ v. 面对 nurse n. 护士→ v. 护理water n. 水→ v. 浇水e.g. She gave me a glass f water. 她给了我一杯水。 Yu shuld water the flwers twice a week. 你应该每周给这些花浇两次水。
3) 形容词转化为动词、名词或副词 narrw adj. 窄的→ v. 使……变窄 red adj. 红色的→ n. 红色 fast adj. 快的→ adv. 迅速地
e.g. The stairs were very narrw.楼梯非常狭窄。 He narrwed his eyes and gazed at the hrizn. 他眯起眼睛凝望着地平线。 We painted the dr bright red.我们把门漆成鲜红色。 I like the way the artist uses red in this painting. 我喜欢画家在这幅作品中对红色的运用。。
请大家判断词性转化类型,然后翻译句子
(1) Let me have a try.(2) Yu culd shulder the task.(3) Yu shuld try yur best t better yur perfrmance.(4)They are discussing the cntent f the stry.
4. 缩略法( Abbreviatin)：用单词或短语的部分内容指代整体。 1) 首字母缩写 Very Imprtant Persn VIP Chief Executive Officer CEO China Central Televisin CCTV Wrld Trade Organizatin WTO Virtual Reality VR Phtshp PS图像处理 2) 单词截短 (Clipping)（截头，去尾，截头又去尾） telephne – phne advertisement – ad广告 influenza -- flu流感
