难点 利用思维导图来帮助记忆信息

①He divided his energies between politics and business.他把精力分别用在政治活动和生意上。
②A fence divides off the western side of the grounds.篱笆把庭院的西面隔开了。
【延伸】divide...into意为“把……分成……”，此短语可用于被动语态，即be divided into，意为“被分为”。如：

让我们分成几个小组吧。
2. look up to钦佩；仰慕
【点拨】look up to意为“尊重/敬仰(某人)”。如：
①Children should look up to their parents.

【延伸】(1)look up 意为“抬头看”。如：

1. Basketball is a much－loved and active sport that is enjoyed by many for fun and exercise.
篮球是一项深受喜爱的且充满活力的运动，被许多人作为娱乐和锻炼而喜欢。
【点拨】(1)much－loved意为“深受喜爱的”。该词是由“副词＋过去分词”构成的复合形容词，在句中可作定语或表语。
如：
Her much－loved brother lay dying of AIDS.
她至爱的兄弟因艾滋病而濒临死亡。
(2)active是形容词，意为“活泼的；积极的”，可作表语和定语。常用短语：take an active part in，意为“积极参加”。如：

如：①Do you often dream at night
你晚上经常做梦吗？

【延伸】include是动词，意为“包括”。如：

【点拨】(2)the number of意为“……的数目/数量”，后接复数名词，作主语时谓语动词要用单数形式。如：
The number of the students in the room is seventeen.
房间里的学生人数是17。
【辨析】the number of与a number of
the number of意为“……的数量”，中心词是number，指的是of后面名词的数量，谓语动词要用单数；a number of意为“许多……”，中心词是这个短语所修饰的复数名词，故谓语动词用复数。如：
