set some other time for the meeting.
二、 用even， let alone， especially， indeed， greatly， a
lot等修饰动词起到突出表意的作用，例如：

movies and PC games. Just imagine， all this can be
done with a cute mouse.

例如：

information， please let me know.
八、 用强调句型“It is（was）＋被强调的部分＋that（who）＋原
句其他部分”来对句子的主语、宾语和状语进行强调、突出说话

originated as a means of survival， earned its status as a
sport.
