设计说明
首先通过一些课文原句的复习直接导入本课时的语法项目——代词it的用法。由it指代动物或者无生命的事物的用法自然导入it指代未知人物的用法，在语境、交流中呈现语法，降低学生的学习难度。it作非人称代词的用法一一呈现，突出其作形式主语和形式宾语的用法。让学生通过对应练习，理清形式主语和形式宾语的真正含义，进一步提高自主学习能力。
教学目标
通过本课节的教学，让学生达成以下目标：
1.知识目标
掌握词汇及词组：quarter,
either,
level,
service,
take

3.情感目标
通过A
visit
to
the
Summer

for
Shanghai的教学，培养学生的家国情怀，让他们更好地了解中国的旅游资源。
重点难点
1.重点：it的各种用法。
