难点名称

名词复数形式的构成方法和变化规则

难点分析

从知识角度分析为什么难

一般来说，可数名词有单数、复数之分，表示“一个”时用单数，表示“多个”时用复数。其中变化方式分为规则变化和不规则变化，将理论规则落实到具体词语的变化，能够举一反三、灵活运用是难点。

从学生角度分析为什么难

学生语法知识较弱，理解困难：三年级学生的认识学习主要以形象感知为主，语法学习较弱，单纯的进行语法规则讲解比较枯燥，学生兴趣低、运用困难。

难点教学方法

1.通过图片展示提高学生的感知能力，帮助学生理解语法知识。

2.通过分类讲解法、列举说明法来提高学生的运用能力，帮助学生梳理知识体系。

导入

1.Hi,everyone.My name is Wendy. Today ,let’s talk about nouns.

知识讲解

（难点突破）

2. So, what are nouns? Well, a noun can be a person, a place, or a thing.

For example, this is Peter. He has a red schoolbag. And he is from Britain. In these sentences, Peter is a person, it’s a noun. Schoolbag is a thing, it’s a noun. And Britain is a country. It’s also a noun.

3.In English, if you want talk about one of something. It’s a singular.

   For example, there is one elephant. The elephant here is a singular.

4.If you want talk about more than one thing. You can change a singular into plural by adding -s at the end of the words.

  e.g. There are two elephants. The elephants here are plural.

5.Now let’s do more examples. (dog-dogs; cat-cats; pear-pears; banana-bananas;)They are all regular plurals.

6.However, there are other regular plurals, too. First, let’s look at the nouns that end with “ch”“sh”“x”“s” and “o”. For these nouns, we just add “-es” at the end of the nouns.

  e.g. “peach” “brush” “box” “bus” tomato” “potato”. The plurals are “peaches” “brushes” “boxes” “buses” “tomatoes” “potatoes”

7.Second, let’s talk about nouns that end with a consonant plus “-y”.For these nouns, we just change “y”into “i”plus “-es”

  e.g. baby-babies; candy-candies; strawberry-strawberries.

8.We know that nouns that end with a vowel plus “y”, we just add “-s” at the end of the words.

  e.g. boy-boys; toy-toys

The plurals we mentioned above are all regular plurals. Because they obey rules.

9.However, there’s bad news. Because there are irregular plurals.

  e.g. sheep -? There is one sheep. / There are two sheep. 

10.let’s look at another example.

  e.g. There’s one child. There are three children.

  child ---?

11.In these examples, “sheep” “child” are singulars, “sheep” “children” are plurals. Why? I can only tell you they came from old English.

12.Well, let’s have a try.

Mouse- ;foot-   ;man-   ;woman-   .They are all irregular plurals.
