15. 构词法 什么是构词法? 在一些原生词的基础上按照一定的语言规律创造新词的方法, 称为构词法. 常见的构词法有合成法、派生法和转化法.
15.2. 合成构词法: 由两个或两个以上的单词合成的词叫合成词. 这种构成新词的方法叫合成法. 这种方法比较灵活, 可以合成名词、形容词、动词、代词、副词等.
注意: “数词+名词(+形容词)” 结构合成的形容词, 其中的名词用单数形式时, 各词之间需要加连字符, 构成“基数词-单数名词(-形容词)” 结构: five-meter-lng; six-year-ld 等.
15.3. 转化构词法: 转化法就是在不改变拼写形式的基础上, 由一种词性转化为另一种词性, 主要有动词转化为名词、名词转化为动词、形容词转化为动词或名词等. 动词转化为名词 t dress a beautiful dress t smell a terrible smelle.g.: Let's g ut fr a walk. (2) Let's have a swim. 名词转化为动词 a cup f water water the flwerse.g.: Did yu bk a seat n the plane?
形容词转化为动词或名词 a black dress the girl in black a narrw street The sea narrws int a channel.
15.4. 派生法: 派生构词法是指通过在词根上添加词缀构成新词. 英语词缀分为前缀和后缀两种. 一般来说, 前缀只是改变词的意义, 但不改变其词类; 后缀不仅改变词的意义, 而且使单词由一种词类转变为另一种词类. 前缀、后缀是英语中常见的扩充词汇的方式.
Review: 已经学过的词缀:① 前缀(1) re + use reusere + cycle recycle rewrite; repeat re- 含有“再; 重复”之意(2) dis + like dislike dis + advantage disadvantage disappear 消失; dislike 不喜欢; disbey 不遵守; disbelieve 不相信; dishnest 不诚实的 dis- 含有“不; 非”之意,主要用在动词之前, 有时用于名词和形容词前, 表示否定, 构成反义词.
(3) un + usual unusual un + happy unhappy infinite 无限的; impssible 不可能的; unable不能的; illegal非法的; irregular 不规则的 un-, in, im, il, ir用在形容词前, 含有"不; 无"之意, 表示否定, 构成反义词.
② 后缀:(1) help + ful helpful hpe + ful hpeful beautiful; successful; wnderful n/v + -ful adj有…性质的, 充满…的(2) hpe + less hpeless hme + less hmeless n + -less adj无…的, 缺少…的(3) humr humrusdanger dangerus nervus; famus; muntainus n + us adj具有…的性质

Reading cmprehensin 2. Many peple knw that rubbish is a big prblem n planet Earth. What many peple dn't knw is that junk has becme a prblem in uter space t. Accrding t BBC News, there are mre than 22, 000 pieces f space junk flating arund the earth. And these are just the things that we can see frm the surface f the earth by telescpes(望远镜). There are als millins f smaller pieces f junk that we can't see.
Objects, like bits f ld space rckets r satellites, mve arund the planet at very high speed, s fast that even a very small piece can break imprtant satellites r becme dangerus t astrnauts. If the tiniest piece f junk crashed int a spaceship, it culd damage the vehicle. T make things wrse, when tw bjects in space crash, they break int many smaller pieces. Fr example, when a U.

T reduce additinal space junk, cuntries have agreed that all new space tls can nly stay in space fr 25 years at mst. Each tl must be built t fall safely int the earth's atmsphere after that time. In the upper parts f the atmsphere, it will burn up. Many scientists are als suggesting different ways t clean up space junk.
In England scientists are testing a metal net that can be fired int space junk. The net catches the junk and then pulls it int the earth's atmsphere t burn up. The Germans are building rbts that can cllect pieces f space junk and bring them back t Earth t be safely destryed. “The prblem is becming mre challenging because we're sending mre bjects int space t help peple use their mbile phnes and cmputers, "says Marc Castrnuv, an Italian space researcher. “The time t act is nw. The lnger we leave the prblem, the bigger it will becme," he says.

15. 构词法 什么是构词法? 在一些原生词的基础上按照一定的语言规律创造新词的方法, 称为构词法. 常见的构词法有合成法、派生法和转化法.
15.2. 合成构词法: 由两个或两个以上的单词合成的词叫合成词. 这种构成新词的方法叫合成法. 这种方法比较灵活, 可以合成名词、形容词、动词、代词、副词等.
注意: “数词+名词(+形容词)” 结构合成的形容词, 其中的名词用单数形式时, 各词之间需要加连字符, 构成“基数词-单数名词(-形容词)” 结构: five-meter-lng; six-year-ld 等.
15.3. 转化构词法: 转化法就是在不改变拼写形式的基础上, 由一种词性转化为另一种词性, 主要有动词转化为名词、名词转化为动词、形容词转化为动词或名词等. 动词转化为名词 t dress a beautiful dress t smell a terrible smelle.g.: Let's g ut fr a walk. (2) Let's have a swim. 名词转化为动词 a cup f water water the flwerse.g.: Did yu bk a seat n the plane?
形容词转化为动词或名词 a black dress the girl in black a narrw street The sea narrws int a channel.
15.4. 派生法: 派生构词法是指通过在词根上添加词缀构成新词. 英语词缀分为前缀和后缀两种. 一般来说, 前缀只是改变词的意义, 但不改变其词类; 后缀不仅改变词的意义, 而且使单词由一种词类转变为另一种词类. 前缀、后缀是英语中常见的扩充词汇的方式.
Review: 已经学过的词缀:① 前缀(1) re + use reusere + cycle recycle rewrite; repeat re- 含有“再; 重复”之意(2) dis + like dislike dis + advantage disadvantage disappear 消失; dislike 不喜欢; disbey 不遵守; disbelieve 不相信; dishnest 不诚实的 dis- 含有“不; 非”之意,主要用在动词之前, 有时用于名词和形容词前, 表示否定, 构成反义词.
(3) un + usual unusual un + happy unhappy infinite 无限的; impssible 不可能的; unable不能的; illegal非法的; irregular 不规则的 un-, in, im, il, ir用在形容词前, 含有"不; 无"之意, 表示否定, 构成反义词.
② 后缀:(1) help + ful helpful hpe + ful hpeful beautiful; successful; wnderful n/v + -ful adj有…性质的, 充满…的(2) hpe + less hpeless hme + less hmeless n + -less adj无…的, 缺少…的(3) humr humrusdanger dangerus nervus; famus; muntainus n + us adj具有…的性质
(4) enjy + able enjyablereuse + able reusable respectable, cmfrtable, valuable; lvable; fashinable n/v + -able adj能…的, 显示…性质的(5) friendly; fatherly; manly n + ly adj相像, 类似 finally; quietly adj + ly adv…地(6) speaker; fighter; wner; directr; editr; peratr v + er/r n动作的执行者

Reading cmprehensin 2. Many peple knw that rubbish is a big prblem n planet Earth. What many peple dn't knw is that junk has becme a prblem in uter space t.

T reduce additinal space junk, cuntries have agreed that all new space tls can nly stay in space fr 25 years at mst. Each tl must be built t fall safely int the earth's atmsphere after that time. In the upper parts f the atmsphere, it will burn up. Many scientists are als suggesting different ways t clean up space junk.
In England scientists are testing a metal net that can be fired int space junk. The net catches the junk and then pulls it int the earth's atmsphere t burn up. The Germans are building rbts that can cllect pieces f space junk and bring them back t Earth t be safely destryed. “The prblem is becming mre challenging because we're sending mre bjects int space t help peple use their mbile phnes and cmputers, "says Marc Castrnuv, an Italian space researcher. “The time t act is nw. The lnger we leave the prblem, the bigger it will becme," he says.
