It may be in your pocket.知识点四：Its nearly noon,and hes still sleeping.nearly是副词，意思是 几乎，差不多。Eg:Hurry up-its nearly time for school.nearly和almost都表示 几乎，差不多。在多数情况下，两者之间没有什么差别。一般来说almost所表达的程度比nearly更接近一些。另外，nearly不能用于修饰否定词，但可被not修饰，not nearly 意为“远不如”;而almost可以和否定词连用。知识点五：Thats where we go out.where we go out.是表语从句，where是引导词。这样的词还有：wh-,that,because等。如：Thats what he said.Thats why I am so worried.The question is whether our parents will agree.The problem is which is heavier.?Step5：巩固练习、检测验收教学反思：
