Answer 1

分析 give up．

解答 答案：give up．這里的主句是一個(gè)祈使句，don't后加上動(dòng)詞原形，表示放棄用動(dòng)詞短語(yǔ)give up，故答案是give up．

點(diǎn)評(píng) 祈使句指的是表示命令、請(qǐng)求、建議或勸告的句子．其主語(yǔ)you常省略，謂語(yǔ)動(dòng)詞用原形，句末用感嘆號(hào)或句號(hào)，讀降調(diào)． 1．肯定的祈使句 （1）動(dòng)詞原形+其他       Stand up，please．=Please stand up．請(qǐng)起立． （2）Be+n．/adj．Be careful!=Look out!=Take care!小心/當(dāng)心�。�3）Let+賓語(yǔ)+動(dòng)詞原形+其它成分  Let's go to school together．咱們一起上學(xué)去吧． 2．否定的祈使句 （1）Don't+動(dòng)詞原形  Don't stand up．別站起來(lái)．   （2）Let型的否定式有兩種："Don't+let+賓語(yǔ)+動(dòng)詞原形+其它成分"和"Let+賓語(yǔ)+not+動(dòng)詞原形+其它成分"．       Don't let him go．/Let him not go．別讓他走．      Let them not play with fire．別讓他們玩火．
