The spirit of these climbers shows us that we should never give up trying to achieve our dreams. give up 意为“放弃”，后面可以接名词、代词或v-ing形式作宾语。注意：如果其宾语是名词，那么名词可以放在 give 和 up 之间，也可以放在 up 之后；如果其宾语是代词，那么代词只能放在 give 和 up 之间。如：My uncle wants to give up drinking wine. 我叔叔想戒酒。Although English isnt easy to learn, I wont give it up. 虽然英语不易学，但我不会放弃。5.
