同学们回想看看我们共学了哪些句型。本单元我们学习的是如何描述物体的位置。陈述句的格式为：sb. /sth.＋be(not)＋介词短语(方位)。如My book is(not)in my bag.我的书在/不在我的书包里。如果将这个句子改为一般疑问句就是将be动词提到句首，即为Is your book in your bag?寻问物体在哪儿要用到特殊疑问，结构为特殊疑问词where＋一般疑问句。如Where is your book?在这里提醒同学们注意的是主谓一致。还是这三个例子，如果要说明的不只一本书，而是几本书，它们分别为“My books are in the bag. Are your books in your bag? Where are my books?”

试一试：你能将方框内恰当的动词形式填入对话空白处吗？如果填对了，说明你掌握了主谓一致的基本原则，如果有错，不必着急，可以向你的老师或者同学请教。
