1That is a book.(改为一般疑问句,并作否定回答） This is my dictionary.(改为一边疑问句,并作肯定回答That`s an English book.(对划线部分提问）me,is,you,excuse,this,pencil,box?(连词成句）

1. Is that a book? No, it isn't.
2. Is this your dictionary? Yes, it is.
3. 应该是对an English book划线部分吧？那么改成： What is that?
4. Excuse me, is this your pencil box? （你应该是题中的your打成了you吧？）

保证正确，望采纳，祝学习进步！
