(站起来是动作,拉伸腿是目的),强调句中的to do结构表目的。 (2)让学生依次用“I + 动词原形 + to + 动词原形”的句式接龙,动作需和“休闲/课堂”相关。(这里会再举两个例子:I open the book to read English. /I take out my pen to write down notes.) 教师在黑板上快速记录学生接龙的句子。 Lead-in 02 01 Lead-in What did we find in the game? 02 I stand up to stretch my legs. I open the book to read English. I take out my pen to write down notes. 本环节继续呈现热身环节的例句,并将不定式结构高亮显示。 将黑板上的学生的句子中的不定式结构依次标记出来,问学生上面的问题。 We made so many sentences with “to + infinitives” (不定式) 01 Lead-in Grammar Tips 02 )为什么叫“不定式”? 英语里的infinitive这个名称,源于语法中“形式不受限定”的特点。 动词的不定式形式,不会随着主语的人称、数、时态变化而改变形式。 比如to read 不管是主语是I、You还是They,形式始终不变;而限定动词(如read、reads、read/red/)会根据主语或时态变化。 中文翻译“不定式”,就是这节对应这个“形式不受限定”的核心特征。 2)不定式的形式: 两种:原形动词和带to的不定式,即to +原形动词 Presentation 03 01 Presentation 03 01 Presentation 03 Answer the questions according to the sentences. -What do you do in your free time? - I play the flute to relax.

I decided to give it a go. Q: I saw my mother paint. At that time, who painted?

A Happy Outdoor Activity — Cycling What do I usually do outdoors? I usually go cycling along the river with my dad, and it’s my favorite outdoor activity. My dad often asks me to ride slowly and carefully. He always tells me to keep away from the busy road to stay safe. We usually choose the quiet path by the river, and we stop sometimes to watch the fish swimming in the water. I also like to take my camera with me to take some beautiful photos during the trip. 01 Production 05 Let’s read a sample. Sometimes, my little brother wants to join us too. Dad makes him sit on the back seat of my bike because he is too young to ride alone. We all feel happy after cycling, and it helps me relax after a busy week at school.
