Question

20．我的表妹英语很好，但是她从不炫耀自己．My cousin is good at English，but she never shows off．．

Answer 1

分析 My cousin is good at English，but she never shows off．

解答 答案：My cousin is good at English，but she never shows off．这里是说客观事实用一般现在时，表示擅长…用be good at，主语是我的表妹My cousin三单，故用is，故My cousin is good at English．连词but表示但是，引出下一句，主语用she代替my cousin，从不never，放在实意动词的前面．炫耀show off，主语三单，故shows off，故答案是My cousin is good at English，but she never shows off．

点评 but作连词，可以连接两个并列成分或两个并列分句，意为"但是，然而"．如：
　　He is young but very experienced．
　　他虽然年轻，但很有经验．
　　Mary likes classical music，but her husband likes rock music．
　　玛丽喜欢古典音乐，而她的丈夫却喜欢摇滚乐．
　　注意：but不能与though/although连用．
