Answer 1

答案： 解析： (1) 去掉the 这里people是泛指. (2) What→how do带有宾语it，所以不用what. (3) animal→animals 由下文中的take the skin off them可推测animal应用复数. (4) eat→ate 讲述过去的事情应使用过去时态. (5) Some us →Some of us some不可修饰人称代词.some of＋us/you/them. (6) √ (7) sometime →sometimes sometime意为“某时”；sometimes意为“有时”. (8) the burnt areas →the burning areas burnt 表“完成，被动”意义； burning表“正在进行”之中. (9) 去掉been go out 表示“熄灭”，不可以用被动形式. (10)cooking→cooked
