3. She likes music and she likes dancing.
4. Maths is difficult but it's important.
5. His favourite subject is history because he likes to learn about the past.

【分析】
解题思路：首先判断每组两个句子的逻辑关系：因果关系用because连接，转折关系用but连接，并列关系用and连接；再根据逻辑关系选择对应连词，将两个句子合并成一个完整句子，注意指代一致（如用it指代前文的科目）。
【解析】
1. 两个句子为因果关系（喜欢生物的原因是它有趣），用because连接，合并为：I like biology because it's fun.
2. 两个句子为转折关系（喜欢美术但不擅长画画），用but连接，合并为：He likes art class but he isn't good at drawing.
3. 两个句子为并列关系（喜欢音乐和跳舞），用and连接，合并为：She likes music and she likes dancing.
4. 两个句子为转折关系（数学难但重要），用but连接，合并为：Maths is difficult but it's important.
5. 两个句子为因果关系（最喜欢历史的原因是喜欢了解过去），用because连接，合并为：His favourite subject is history because he likes to learn about the past.
【答案】
1. I like biology because it's fun.
2. He likes art class but he isn't good at drawing.
3. She likes music and she likes dancing.
4. Maths is difficult but it's important.
5. His favourite subject is history because he likes to learn about the past.
