Light music is my favourite because it helps me relax.Sometimes I feel tired after a day's study,and soft music helps me calm down. Last week,our school held a music festival.Since many of us like music,we all joined in the activities. My fiiends and I prepared a performance together. As we did not have many instruments,our teacher suggested making music with everyday objects.We chose bottles and paper,for we wanted to show that music could come from everyday life Our classmates enjoyed our performance because it was creative.I think music is more than pleasant sounds.It is a way to share feelings and understand each other better. 重点表达 because:说明喜欢音乐或表演受欢迎的直接原因。 Since:以“我们喜欢音乐”这一已知情况解释参加活动的原因。 As:说明采用日常物品制作音乐的原因。 for:在主句后补充选用瓶子和纸的理由，前面用逗号。 写作答案不唯一，内容完整、语法正确，并能用所学连词说明原因即可。 Unit 5 Music speaks 语法讲义 语法点一：because和for表示原因 一、核心语法讲解 because和for都能说明原因，但语气、句中位置和表达重点不同。 1. because意为“因为”，强调具体、直接的原因，语气较强，常回答why引导的问题。 基本结构：主句 + because + 从句；或Because + 从句，主句。 I like this piece of music because it helps me relax. 2. for意为“因为，由于”，用于补充说明或给出判断的理由，较正式，多见于书面语。 基本结构：主句，for + 主语 + 谓语 + 其他。前面常用逗号。 for表示原因时，应把它引出的分句放在主句后，不能单独成句。 We stayed inside, for it was raining heavily. 3. because和because of的区别：because + 句子；because of + 名词、代词或-ing短语。 He stayed at home because he was ill. He stayed at home because of his illness. 4. for引出的情况也可用来支持前面的判断，而不只是说明事件发生的直接原因。 He must be at home, for I can hear him playing the piano. 解析：听见他弹钢琴，是前面判断的理由。 二、教材原句解析 1. Many people have heard of him because he's a great musician. 解析：because从句放在主句后，直接说明许多人听说过他的原因。 2. Sandy loves listening to light music, for it is relaxing. 解析：for引出补充理由，位于主句后，前面有逗号。 3. He used the sound of water, for he wanted to remind the audience of nature. 解析：for说明使用水声的理由，两个分句都在谈过去的事情。 三、易错点提醒 1. because后接完整句子；because of后不直接接普通陈述句。 because it rained / because of the rain（均可；后面结构不同） 2. for表示原因时通常不用于独立回答why；注意区别介词for，如wait for the bus。 3. 同一组因果分句中，不用because和so重复连接；选用其中一个即可。 （✖）Because it was raining, so we stayed at home. （✔）Because it was raining, we stayed at home. 语法点二：since和as表示原因 一、核心语法讲解 since和as都可表示“既然、由于、因为”，常说明已知或较明显的原因，语气比because弱。 1. 基本结构：Since/As + 原因从句，主句；或主句 + since/as + 原因从句。 2. since常说明双方已知的理由；as的用法相近，两者在许多语境中可以互换。 Since/As everyone is here, let's begin the music lesson. 3. 原因从句的时态取决于实际时间，没有固定的“主将从现”规则。 I will talk to him because he was late yesterday.（主句将来，从句过去） 4. 综合辨析：because突出直接原因，常回答why；since/as多说明已知原因； for常位于主句后补充理由，书面色彩较强。because、since、as并非在所有语境中只能选一个。 二、教材原句解析 1. Since his father was also a musician, he learnt about music early in his life. 解析：since说明学习音乐的原因；原因从句在前，后面用逗号与主句隔开。 2. As he was clearly very talented, it is no surprise that he became a great musician. 解析：as引出的原因是“他很有天赋”，主句说明结果。 3. Tan uses the sounds of nature a lot in his music, as he likes them very much. 解析：as从句也可放在主句后，说明大量使用自然声音的原因。 三、易错点提醒 1. since的两种常见意义：原因用法是“既然”；时间用法是“自从……以来”。 Since you are ready, let's start.（原因） I have played the violin since I was six.（时间） 2. as不总表示原因，还可表示“当……时”，也可作介词表示“作为”。 As I was leaving, Tom called.（时间）/ She works as a music teacher.（作为） 3. 不要只凭位置判断since和as；两者表示原因时均可放在句首或句中。 4. 注意逻辑顺序：because/since/as说明原因；so引出结果。 It was raining, so we stayed inside. / We stayed inside because it was raining.
