☆教材解读☆
1.Agriculture is all about growing plants and raising animals for food.?
raise是及物动词,意思是“饲养”。

我妈妈养了许多鱼。
【拓展】　raise 的其他含义:
(1)举起;提起。
Raise your hand! 举起手来!
(2)增加;提高。

(6)筹集;募捐。

2.Now,something new is growing at the top of the stem.?
something是不定代词,意思是“某事;某物”,与其相似的还有somebody,anything,anybody,everything,everybody,nothing,nobody等。主要用法:
(1)不定代词作主语时,常被看作单数第三人称,所以谓语动词也是单数形式。
There’s something wrong with my watch.
我的手表有些毛病。
(2)形容词修饰不定代词时,放在后面,叫作后置定语。
　　I want to have something delicious.
我想吃好吃的东西。
(3)动词不定式修饰不定代词时,也要放在后面。
She has something interesting to tell you.
她有一些有趣的事告诉你。
3.I’m going to look after my plant carefully.?
look after意思是“照顾;照料”,相当于 take care of。后面接的宾语既可以是人,也可以是物。after 在这里是介词, 后面可接名词或者代词。
She could look after herself.
=She could take care of herself.
她能够照顾自己。

(5)look like看起来像。

(6)look over仔细检查。

[设计意图]　学生通过阅读课文,了解重点内容,并且通过提出问题、回答问题来巩固对课文的理解和掌握;反复朗读课文,根据课文内容填空。
StepⅥ.Complete Let’s Do It!
Ask the students to read the diary and answer the questions in No.1 and fill in the blanks in No.2 by themselves.
[设计意图]　Let’s Do It! 部分中的No.1重点是阅读训练教学,针对课文进行训练。No.2训练文中出现的植物常识,让学生对植物有细致深刻的了解。
StepⅦ.Task
GROUP WORK:Let’s Do It! No.3
Ask students in groups to come to the front of the classroom,and they can present their ideas about plants.
[设计意图]　No.4的重点是实践练习,同学们通过小组合作来完成练习。以“现实中我们吃植物的什么部分”为话题,提供了一个语境完整、内容丰富的话题,自然呈现本单元的核心句型,为学生进一步输出语言提供了口语示范。

语法精讲
构词法——转化词、派生词
(一)转化词
转化词:英语中,由一种词性转化成为另一种词性叫词类的转化。常见的有名词转化为动词,动词转化为名词,形容词转化为动词。
1.名词转化为动词
water 水→water浇水　plant 植物→plant种植
2.形容词转化为动词
cool 凉爽的→cool使凉爽　dry 干燥的→dry使变干,弄干
(二)派生词
派生词:在词干前后加词缀而构成的新词,称为派生词。加在词干前面的为前缀,后面的为后缀。
1.后缀
(1)构成名词的后缀常用的有:-er,-or,-ist,-ness,-ment,-tion,-ress 等。例如:dancer 舞蹈家;inventor 发明家;scientist科学家;artist画家; government政府;actress 女演员。
(2)构成形容词的后缀常用的有:-ful,-less,-able,-ous,-y 等。例如:helpful有用的;cloudy 多云的;enjoyable令人愉快的; dangerous危险的; careless 粗心的。
2.前缀
前缀一般不造成词类的转变,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。例如:unhappy不高兴的;dislike不喜欢;impossible 不可能的。
