Ⅱ. 连词成句。
1. "because" give a to use we reason (.)
2. likes music she to pictures and listen draw to (.)
3. as you why who the same likes and subjects (?)
4. good not science I like I'm at but the much very class (, .)

1. We use “because” to give a reason.
2. She likes to listen to music and draw pictures.
3. Who likes the same subjects as you and why?
4. I'm not good at science, but I like the class very much.

【分析】做连词成句题时，首先要明确句子类型（陈述句/特殊疑问句），先找出主语、谓语等核心成分，再结合固定搭配、并列连词的用法排列词汇，最后调整大小写和标点符号。例如特殊疑问句以疑问词开头，陈述句需遵循“主语+谓语+其他”的基本结构，并列动作用and连接、转折关系用but连接。
【解析】1. 先确定主语We，谓语动词use，结合固定搭配“use sth to do sth”，将“because”作为use的宾语，“to give a reason”作目的状语，调整大小写和标点，得到We use “because” to give a reason。2. 主语为She，谓语动词likes，结合“like to do sth”结构，两个并列动作“listen to music”和“draw pictures”用and连接，得到She likes to listen to music and draw pictures。3. 这是特殊疑问句，以疑问词Who开头，谓语likes，宾语“the same subjects”，搭配“as you”，再补充疑问词why，得到Who likes the same subjects as you and why。4. 用并列连词but连接两个分句，前半部分是“I'm not good at science”，后半部分是“I like the class very much”，中间用逗号分隔，得到I'm not good at science, but I like the class very much。
【答案】1. We use “because” to give a reason.
2. She likes to listen to music and draw pictures.
3. Who likes the same subjects as you and why?
4. I'm not good at science, but I like the class very much.
