初中英语的不定冠词有哪些（英语so和such与不定冠词的使用）

大家好，我是一名两个孩子的爸爸。当孩子在学习中会遇到很多问题或者知识点，我用文章的形式或者视频（后续）的形式呈现给大家。一是和有着相同经历的家长朋友们共同探讨孩子的学习；二是分享相关的知识点，用来补充缺乏这些知识的家长们。在有些文章里会穿插不同年龄段的不同学科的知识，主要是为了丰富和扩展更多的知识和学习乐趣。现在分享对句子的提问、so和such与不定冠词、英语中使用-ing分词的几种情况、英语中的“单数”、名词的复数构成的几种形式知识。

一、对句子的提问

新目标英语在命题中有将对句子划线提问这一题型取消的趋势，现在采取的作法是对一个句子

进行自由提问。例如：

句子：

The boy in blue has three pens.

提问：

1. Who has three pens?

2. Which boy has three pens?

3. What does the boy in blue have?

4. How many pens does the boy in blue have?

很显然，学生多了更多的回答角度，也体现了考试的灵活性。再如：

句子：He usually goes to the park with his friends at 8:00 on Sunday.

提问：1. Who usually goes to the park with his friends at 8:00 on Sunday?

2. Where does he usually go with his friends at 8:00 on Sunday?

3. What does he usually do with his friends at 8:00 on Sunday?

4. With whom does he usually go to the park at 8:00 on Sunday?

5. What time does he usually go to the park with his friends on Sunday?

6. When does he usually go to the park with his friends?

二、so、such与不定冠词的使用

1.so与不定冠词a、an连用，结构为“so 形容词 a/an 名词”。如：

He is so funny a boy.

Jim has so big a house.

2.such与不定冠词a、an连用，结构为“such a/an 形容词 名词”。如：

It is such a nice day.

That was such an interesting story.

三、使用-ing分词的几种情况

1.在进行时态中。如：

He is watching TV in the room.

They were dancing at nine o'clock last night.

2.在there be结构中。如：

There is a boy swimming in the river.

3.在have fun/problems结构中。如：

We have fun learning English this term.

They had problems getting to the top of the mountain.

4.在介词后面。如：

Thanks for helping me.

Are you good at playing basketball？

5.在以下结构中：

enjoy doing sth 乐于做某事

finish doing sth 完成做某事

feel like doing sth 想要做某事

stop doing sth 停止做某事

forget doing sth 忘记做过某事

go on doing sth 继续做某事

remember doing sth 记得做过某事

be busy doing sth 忙于做某事

四、英语中的“单数”

1.主语的第三人称单数形式，即可用“he,　she,　it”代替的。如：

he,she, it，my friend, his teacher, our classroom, Tom, Mary's uncle

2.名词有单数名词和复数名词。如：

man（单数）---men（复数） banana（单数）---bananas（复数）

3.动词有原形，第三人称单数形式，-ing分词，过去式，过去分词。如：

go---goes---going---went---gone

work---works---working---worked---worked

watch---watches---watching---watched---watched

当主语为第三人称单数的时候，谓语动词必须用相应的第三人称单数形式。如：

The boy wants to be a sales assistant.

Our English teacher is from the US.

Their daughter makes her breakfast all by herself.

五、名词的复数构成的几种形式
