四、字词与词汇
五、语法与句型
句型一：start ding sth. 开始做某事
【规则】
start ding sth. = start t d sth.，表示"开始做某事"。
表示长期习惯或爱好时多用 start ding sth.；描述某次具体的开始可用 start t d sth.。
when 引导时间状语从句，说明开始的时间。
【结构公式】
主语 + start(ed) ding / t d sth. + when 从句.
【教材例句】
I started taking pian lessns when I was six.
I learnt t play it at the age f five.
句型二：find it + 形容词 + because ...
【规则】
it 在句中作形式宾语，真正的宾语是后面谈论的那件事（弹钢琴）。
形容词作宾语补足语，说明对这件事的感受：challenging / easy / difficult / interesting。
because 引导原因状语从句，说明产生这种感受的原因。
【结构公式】
主语 + find(s) it + adj. + because 从句.
【教材例句】
I still find it challenging because it has s many keys and requires a lt f finger strength.
【易错纠正】
句型三：It takes ... t d sth.
【规则】
It takes + (sb.) + 时间 / 精力等 + t d sth.，表示"做某事需要花费……"。
it 为形式主语，真正的主语是动词不定式短语。
【结构公式】
It takes + a lt f practice / time + t d sth.
【教材例句】
S it takes a lt f practice t play ntes well.
六、学习支架
信息卡：三种中国传统乐器
对话支架：谈论乐器学习经历
询问：Are yu gd at playing the / D yu play a musical instrument?
经历：I started taking ... lessns when I was ... / I learnt t play it at the age f ...
感受：I find it easy / challenging because ...
原因：It has s many keys. / It requires a lt f finger strength. / It requires skilled bw cntrl.
总结：It takes a lt f practice t play it well.
七、知识要点
1. 乐器名词前加定冠词 the
英语中表示"演奏某种乐器"时，乐器名词前要加定冠词 the，如：play the pian / play the vilin / play the guzheng / play the erhu。注意：球类、棋类名词前不加 the，如 play basketball / play chess，二者不要混淆。
2. challenging 的词性与用法
challenging 是形容词，意为"有挑战性的"，由动词 challenge（挑战）加后缀 -ing 构成。常见结构：find sth. challenging 觉得某事有挑战性；a challenging jb 一份有挑战性的工作。教材原句：I still find it challenging because it has s many keys.
3. require 的三种常见搭配
① require + 名词：It requires a lt f finger strength. ② require + ding（主动形式表被动意义）：The machine requires repairing. 这台机器需要修理。③ require + sb. + t d sth.：The teacher requires us t practise every day. 本课重点掌握第①、③种。
4. at the age f ... 与 when 从句表"在……岁时"
教材中出现了两种表达：I started taking pian lessns when I was six. 和 I learnt t play it at the age f five. 二者可以互换：at the age f five = when I was five (years ld)。注意 age 前用定冠词 the。
5. seem 的用法：It seems hard t play it well.
seem 作连系动词，意为"似乎、好像"，常见结构：seem + adj.（It seems hard.）；seem t d sth.（He seems t knw it.）；It seems that 从句。教材句中 It seems hard t play it well. = It seems that it is hard t play it well.
