107. 因为玛吉请了三天病假，所以她必须把落下的课补上。

[误] Since Maggie asked for a sick leave of three days,she should make up for her lost lessons.

[正] Since Maggie asked for a sick leave of three days,she should make up her lost lessons.

注：同样表示“弥补，补偿，补足”，make up 后面一般接具体的名词，如：make up a missed lesson（补课）
，a make-up examination（补考）等；而 make up for 后面的名词通常比较抽象，如：make up for the lost time（弥补时间上的损失），make up for one\'s defects（补其所短）等。
