����以这样说：
"姐姐在阳台上练习英语。"
"My sister is practicing Engpsh on the balcony."
"balcony" 是英文中阳台的意思。它来自法语 "balcon"，本意是 "楼梯间的栏杆"。
这句话的其他表达方式包括：
"姐姐在阳台上学习英语。"
"My sister is learning Engpsh on the balcony."
"姐姐在阳台上训练英语口语。"
"My sister is exercising her Engpsh speaking skills on the balcony."
另外，"practice" 和 "exercise" 都可以表示 "练习" 的意思，但 "practice" 更强调经常性的练习，而 "exercise" 则更强调单次的练习。
