摘要:
该初中英语课件聚焦两种核心句型(S+V+IO+DO、S+V+DO+OC)及并列连词(and, but, or, so),通过“句子结构分析”导入,复习S+V+O等旧句型,搭建“复习-新授-转换-应用”学习支架,帮助学生逐步掌握语法知识。
其亮点在于采用结构化教学,如通过动词分类表(to/for搭配动词)、宾补形式表格梳理知识,培养语言能力;结合“生态系统”主题设计连词练习,将语法与主题融合提升思维品质。任务型输出活动(用句型和连词写生态系统内容)促进学习能力,学生可学以致用,教师可直接使用清晰活动设计提升教学效率。

Learn to use S+V+IO+DO、S+V+DO+OC
Verbs and sentence structures (Ⅱ)
Some verbs can take two objects, a direct object and an indirect object.
S+V+O (indirect)+O(direct) → The sun gives ocean animals light and heat.
S V O O
We can change the order of the direct and indirect objects by using to or for.
The sun gives light and heat to ocean animals.
We should build a better home for local wildlife.

谓语动词必须跟有两个宾语才能表达完整的意思。这两个宾语一个是动作的直接承受者,另一个是动作的间接承受者。有的谓语动词后面出现双宾语 (人)间接宾语和(物)直接宾语。
“主语 + 及物动词 + 间接宾语 + 直接宾语”。在表达时,常常是间接宾语在前,直接宾语在后。
He gave me a bike.
This term, Mr. Wang teaches us Chinese.
在具体表达时,可以将直接宾语提前。如果直接宾语在前,间接宾语在后,要根据具体的意思在间接宾语前加上相应的介词。
My parents bought some storybooks for me.
They gave a lot of storybooks to us.
主+谓+间宾+直宾(S + V + IO +DO)。
Nancy gave me a hat.
IO (间接宾语 人) DO (直接宾语 物)
Hobo built Eddie a tent.
IO (间接宾语 人) DO (直接宾语 物)
在这一结构中,间接宾语可改成一个由to/ for引导的短语。
在双宾语句子中
间接宾语往往是人,
直接宾语往往是物。

give hand lend
offer pass post
read sell send
show take teach

get/leave/make/order
/pick/prepare/save
+sb. sth.

An object complement can also follow a direct object to give more information about the object.
S+V+O (direct)+C→ The mother bird keeps the eggs safe.
S V O C
宾语补足语(C或OC),简称宾补(宾语补足语用于补充说明宾语的情况)
补足语跟在宾语后,表明宾语的状态。
S + V + DO + OC.
Forms of object complements Examples

Learn to use and, but, or, so
We use conjunctions like and, but, or and so to join ideas together.

When joining more than two expressions,we usually only put and before the last.

Oceans provide food for many animals, produce oxygen and store heat from the sun.
We use but to join ideas that are different.
This kind of fish can find enough space here. They can find little food.

We use and to join similar or related ideas.
Birds can live in the forest. They can also live in the wetland.
Birds can live in the forest or in the wetland.
In negative sentences, we use or to join two or more ideas.
The deep ocean isn’t warm. The deep ocean isn’t bright. The deep ocean
isn’t noisy.

We use so to express the result of something.
Deserts are dry. Some plants keep water in their leaves.
