Unit 25 The weekend shopping 周末购物
一、重点单词及拓展：
1. 复习动词ing的学问
1〕用于现在进行时，表示“正在发生的动作〞，结构为主语+be+Ving 例：Look! The boys over there are playing table tennis.
Can you see that kite? It is flying in the sky.
留意：一些表示思想、感情和感觉的动词，如love, know, want, hope等单词没有进行时态。

2）动名词，既具有动词的性质,又具出名词的性质，在句子中通常做主语、表语、宾语、定语等成分。

尝试分析以下句子中动名词所做的成分：
Playing football is Tom’s favourite thing.
Tom’s favourite thing is playing football.
We are all good at playing football.
That shopping mall is wonderful, we all like to go there.
3）动词ing的变化规那么：
A.直接在动词后加ing, 如dodoing thinkthinking
B.不发音字母e结尾的动词，去e再加ing,如eing, makemaking
C.“辅元辅〞结构的动词，双写尾字母再加ing, 如beginbeginning
stopstopping, sitsitting
D.以ie结尾的动词，变ie为y再加ing, 如diedying, lielying, tietying
造句练习：
1）今日天气真好，让我们去购物吧！
2）看！两只小鸟正在空中唱歌。

3）明天一起去游泳怎么样？
4）让我们一起制作一个阅读清单吧！
5）那些孩子是在跳舞吗？是的，他们在跳。

2.Need〔需要〕的用法
1）做情态动词，后接动词原形，否认形式为needn’t + 动原，常用于否认式和疑问句中。

此外，must引导的一般疑问句，确定答复用must，否认答复要用needn't。

例：You needn’t say sorry to me. It doesn’t matter.
Need we still stay here? Yes, you need./No, you needn’t.
Must we still stay here?Yes, you must./No, you needn’t.
2)做实义动词，可以直接接名词、代词作宾语；也可以接to do表示需要做某事，接doing时表示需要被做〔被动语态〕。

留意，此时的need有人称和时态的变化。

例：Do you need any tea for lunch?
He doesn’t need us to go with him.
The dog needs feeding. 小狗需要〔被〕喂了。

〔表被动〕
造句练习：
1）我们需要五只铅笔、四块橡皮和六把尺子。

2）你需要我帮你学英语吗？
3）Tom不需要制作购物清单。
