英语语法问题不是说both.and作为并列连词只能接词语和词组吗?那He succeeded both because

那这句话both he works hard and I work hard为什么是不对的呢？ 有点罗嗦，英语讲究简洁，可以改为 Both he and I work hard

你那样写，不能你错，只能说不是更好，不是最标准英语表达法，当然如果严格地说，那那样写也会被认为是错误的，为了更保险一点，不建议那样写，OK?，因为英语讲究简洁, 能简洁，就一定要简洁，如果不能简洁，就一定不能简洁. 就像下面几个句子 This is not my book, mine is red (my book is red 不建议这样写 ) Their classroom is small, but ours is big .. This is his father, mine is over there Whose pen is this ? It is mine / hers （不建议这样写it is my pen / her pen )
