Karl (with 和……一起) his parents and his brother is (in 在)China .
加油!不明白再问!with 和and 不重复吗SORRY，没注意后面有and

那就是
Karl (as well as ) his parents and his brother is (in )China .是一个空Karl (except) his parents and his brother is (in )China .什么意思应该是： Karl (besides ) his parents and his brother is (in )China .

除他的父母亲和哥哥外，卡尔在中国。（意思是他们都在中国）
