【知识点拨】
1．make a difference
make a difference(to…)意为“(对……)有影响；(对……)起作用”。difference前面还可用some，big，great等词修饰，make a big/great difference表示“有重大影响；起很大作用”。
例句：Exercise made a big/great difference to her.锻炼对她产生了很大的作用。
【拓展】
make no difference 没有影响；无关紧要 make all the difference关系重大；大不相同
例句：Whether she is rich or not makes no difference to me.她是否富有对我并没有影响。
A few kind words at the right time make all the difference.在适当的时候说几句体贴的话效果迥然不同。
2．imagine
imagine作动词，意为“想象；设想”，不可用于进行时。其名词形式为imagination，意为“想象”。
