英語六級-聽力口語關鍵句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?

點睛　

drop one course的意思是“退掉一門課程”。drop的用法在前面已經(jīng)講到，這里不再贅述。pick up在本句中意為“重新學習，繼續(xù)學習”，正好與drop的意思相對。如：
Today we will pick up where we finished last Friday. 今天我們將接著上周五的內(nèi)容繼續(xù)學習。
