Not only can we get food and wood from trees, but also we can use trees to build many things, such as beds, chairs and our houses. Trees can stop wind and water from carrying the soil away.

If you put a seed in the ground and give it water and energy from

语法点集中攻坚
Unit 2
Plant a Plant!
构词法
语法讲堂
考点 1
派生法
考向一
后缀
(1)构成名词的后缀常用的有：
er , or , ist , ness , ment ,
tion , ess , ing等。
eg：illness疾病； government政府；
actress女演员； meeting会议
所谓派生，即在原词上加前缀或后缀构成另一个与原意略有不同或截然相反的词。
(2)构成形容词的后缀常用的有：
ful , less , able , ous , y 等。
eg：helpful有用的； cloudy 多云的；
enjoyable令人愉快的； dangerous危险的；
careless 粗心的
(3)构成副词的后缀，常用的有： ly。
eg：slow—slowly 缓慢地；
easy—easily容易地
典例
I’m thankful to the teacher for her __________
on my interview. (suggest)
suggestions
【点拨】我很感谢老师给我(提出)的面试建议。形容词性物主代词her后应用名词，suggest直接加 ion构成名词；此处用复数更合适。
前缀
前缀一般不造成词性的转变，而只引起意思上的变化，前缀中有相当一部分可构成反义词，常用的有un , dis , im 等。
eg：unhappy不高兴的；
dislike不喜欢；
impossible 不可能的。
考向二
典例
I think it’s ________ to judge a person before you really know him. (fair)
unfair
【点拨】我认为在你真正认识一个人之前对他进行评价是不公平的。be动词后面应用形容词，fair“公平的”是形容词，其前加un 构成unfair“不公平的”。
考点 2
转化法
常见的有名词转化为动词，形容词转化为动词。
(1)名词转化为动词
eg: water 水→water浇水
plant 植物→plant种植
(2)形容词转化为动词
eg：cool 凉爽的→cool使变凉、冷却
dry 干燥的→ dry使变干
(3)动词转化为名词
eg: look 看；瞧→look 看；瞧
swim 游泳→swim 游泳
典例
—What was Linda doing at that time
—Oh, she was going for a _______. (walk)
walk
【点拨】句意：——琳达那个时间在做什么？——哦，她在散步。考查词的转化。采用转化法。walk作动词时是“走路”的意思，此句中应用名词walk“散步”。

1．The children were all ________ (激动) because of the games.
2．Mark does his homework________ (认真地) every day.

12．Linda is the big ________of the car race.
13．Do you know about the ________ culture
invention
winner
eastern
usual , win , polite , east , invent
【点拨】句意：琳达是这次汽车比赛的大赢家。win是一个动词，意思是“赢，胜利”。根据这句话的意思可知，这里是说Linda是个大赢家，故应该用它的名词形式，即winner。
14．We should always speak ________to our parents.
15．It is ________ very crowded(拥挤的) here.
politely
usually
返回
usual , win , polite , east , invent
【点拨】句意：我们应该总是有礼貌地跟我们的父母说话。polite是一个形容词，意思是“有礼貌的”，在句中可以作表语或定语。根据句意可知，这里修饰动词speak，故应该用副词形式，即politely。
【点拨】句意：这儿通常很拥挤。这里需要用表示频率的词usually。
