Question

2．上車(chē)前請(qǐng)排隊(duì)，不要擁擠．
Stand in line before getting on the bus．Don't push your way onto the bus．

Answer 1

分析 Stand in line before getting on the bus．

解答 答案：Stand in line before getting on the bus．這里是祈使句，用動(dòng)詞原形開(kāi)頭．排隊(duì)用stand in line，上車(chē)前before getting on the bus，before是介詞，表示在…之前，后跟動(dòng)名詞．故答案是Stand in line before getting on the bus．

點(diǎn)評(píng) 祈使句的幾種形式：
1．肯定祈使句（謂語(yǔ)動(dòng)詞用動(dòng)詞原形）．如：Be careful!小心！
2．否定祈使句（在謂語(yǔ)動(dòng)詞前加Do not/Don't/Never）．如：Don't open the door．不要開(kāi)門(mén)．  
3．Let開(kāi)頭的祈使句（Let's/Let sb+動(dòng)詞原形）．如：Let me have a try．讓我試試吧．
