英语六级-听力口语关键句79. Well, can't you drop one course and pick i

79. Well, can't you drop one course and pick it up next semester?

点睛　

drop one course的意思是“退掉一门课程”。drop的用法在前面已经讲到，这里不再赘述。pick up在本句中意为“重新学习，继续学习”，正好与drop的意思相对。如：
Today we will pick up where we finished last Friday. 今天我们将接着上周五的内容继续学习。

pick up含义丰富，除了“重新学习”以外，还有很多其他常用含义：
