解析
【分析】
本题为汉译英连词运用练习题，解题思路如下：1. 先分析每个中文句子的逻辑关系，确定对应连词：表因果用because，表转折用but，表并列/顺承用and；2. 准确翻译核心词汇，如“最爱的”译为favourite，“学科”译为subject，“旅游”译为travelling等；3. 遵循英语句式结构，注意连词的位置及细节表达（如冠词、主谓一致等），确保翻译符合英语习惯。
【解析】
1. 句子逻辑为因果，用because连接，“他最爱的学科”译为His favourite subject，“地理”是geography，“喜欢旅游”译为likes travelling，组合得His favourite subject is geography, because he likes travelling.
2. 句子逻辑为转折，用but连接，“不擅长科学”译为I'm not good at science，“很喜欢科学课”译为I like the class very much，组合得I'm not good at science, but I like the class very much.
3. 句子逻辑为并列顺承，用and连接，“喜欢所有学科”译为I like all the subjects，“总是学习很努力”译为I always work very hard，组合得I like all the subjects, and I always work very hard.
4. 前半句“我最喜欢的学科是英语”译为My favourite subject is English；后半句逻辑为并列，用and连接，“它很有用”译为It's useful，“我的英语老师很好”译为my English teacher is really nice，组合得My favourite subject is English. It's useful, and my English teacher is really nice.
5. 前半部分是因果（用because），后半部分是转折（用but），“我喜欢语文”译为I like Chinese，“因为它有趣”译为because it's fun，“但是我不喜欢数学”译为but I don't like maths，组合得I like Chinese because it's fun, but I don't like maths.
