This model plane is yours.一般疑问句并作否定回答
They are often go to school.改错
The music isn`t sound nice.改错
It`s getting late,let`s going home.改错

答案

Is this model plane yours 这是你的模型飞机么
否定回答：NO,it isn't.不,它不是.
They are often go to school-----去掉are这个句子是一般现在时态,应该保留频率副词often,因为后面已经有了谓语go所以应该去掉系动词are
改后：They often go to school 他们通常去学校
The music isn`t sound nice.-----去掉isn`t在sound后面加not表示否定,sound是半系动词,is是系动词,所以按照句意应该去掉is
改后：The music sound not nice 这首音乐听起来不好
It`s getting late,let`s going home----going改为go,let sb do sth 让某人做某事（固定短语）
改后：It`s getting late,let`s go home 现在晚了,让我们回家吧.
