【语法解读】
一、概述
构词法是利用词形变化的规律来构成词汇的方法。英语的构词法主要有三种:合成法、
派生法和转化法。
二、合成法
合成法是将两个或两个以上的词结合构成一个词,包括形容词、名词、动词和副词等。
1.合成形容词:warm-hearted, hard-working, peace-loving等。
2.合成名词:blackboard, website, classroom等。
3.合成动词:overcome, download等。
4.合成副词:everywhere, downstairs等。
三、派生法
在一个单词前面或后面加上一个词缀构成新词,这种构词法叫派生法。加在单词前面
的词缀叫前缀,加在单词后面的词缀叫后缀。
1.常见前缀
en-(使……处于某种状态) enable使能够
un-(不,非;表示否定) unhappy不快乐的
dis-(不,非;表示否定) disagree不同意
inter-(相互,在……之间) interview面试,采访
mis-(错误地) misunderstand误解
re-(再,重复) retell复述
tele-(远的) television电视
2.常见后缀
-or/-er (从事某种职业的人,名词后缀) actor演员 singer歌手
-ful(充满……的,形容词后缀) successful成功的
-tion(表动作、状态,名词后缀) celebration庆祝
-less(没有、无,形容词后缀) homeless无家可归的
-y(表性质,形容词后缀) healthy健康的 windy有风的
-ing(形容词后缀) interesting有趣的 relaxing使人放松的
-al(……的,形容词后缀) traditional传统的 natural自然的
-able(能……的,形容词后缀) comfortable舒适的 enjoyable令人快乐的
-ed(形容词后缀) surprised吃惊的 excited兴奋的
-ly(以某种方式,副词后缀) quickly快速地 happily快乐地
四、转化法
把一个单词由一种词性转化为另一种词性,这种构词法叫转化法。
1.名词转化为动词
show n.展览,展示→ show v.表演,展出 water n.水 → water v.浇水
2.形容词转化为动词
slow adj.慢的→slow v.(使)放慢速度
3.动词转化为名词
walk v.散步,走→walk n.散步
look v.看→look n.看
4.形容词转化为名词
black adj.黑色的→black n.黑色
light adj.明亮的→light n.光线
5.副词转化为形容词
hard adv.努力地→hard adj.困难的

【参考范文】
As we know, the environment around us is getting worse and worse. In my hometown, some chemical factories always pour waste water into the river. And they also produce terrible gas. So I think we must do something to protect the environment.
How to protect the environment First, as a student, we should use cloth bags instead of plastic bags when we go shopping. Second, we had better reuse the old textbooks as possible as we can. Third, we should never forget to turn off the lights when we leave the classroom.
In a word, we must try our best to protect our environment. I believe we can make the world a better place to live in.

Ⅲ.阅读理解(主题:绿色生活·建议用时6')
(2023·菏泽二模)
Even if you shop with plastic bags, always remember to recycle them. Most
families don’t realize the importance of eco-friendly living—especially children. So how can you help children start seeing green Well, here are a few suggestions.
Don’t buy toys—borrow instead. If kids are concerned, most toys start to lose their shine(光彩).Don’t let the unloved toys gather dust around the house—instead, join a local toy library and give them to the library. And if you do buy new toys, try to buy toys made from wood and other eco-friendly materials.
Spend time outside.Make sure your child spends time learning to be outside. Let him/her get involved in nature by planting a tree, building a birdhouse, or taking a bike ride in a nearby park.
Teach green.Even if your child doesn’t receive an environmental education in the classroom, there’s no reason that you can’t spread the word at home. Let your kid help out with separating your recyclables.
Stick with eco-friendly entertainment. Most kids may not seem to be interested in the subject on the environment, but put it in a TV show and they’ll change their minds. Give them a taste of the online cartoon show, and you’ll finally find the children learn it happily.
1.The phrase “help children start seeing green” can be replaced by “_______”.
A.help children see the green color
