Question

5．cross，careful，when，the，be，street，you．
Be careful when you cross the street．/When you cross the street，be careful．．

Answer 1

分析 當(dāng)你穿越街道時(shí)要小心．

解答 答案：Be careful when you cross the street．/When you cross the street，be careful．依照提示可以推斷語(yǔ)意與"小心過(guò)馬路有關(guān)"．祈使句是用來(lái)命令人做某件事，而開頭的動(dòng)詞必須為動(dòng)詞原形；when（當(dāng)?shù)倪B接詞）所引導(dǎo)時(shí)間狀語(yǔ)從句的謂語(yǔ)指瞬發(fā)動(dòng)作或持續(xù)性，時(shí)態(tài)和主句一致，而when引導(dǎo)的從句可放在主句前或主句后，若放在主句前，主從句之間要用逗號(hào)隔開．故答案為Be careful when you cross the street．/When you cross the street，be careful．

點(diǎn)評(píng) 本題考查同學(xué)組合句子的能力，本題要特別注意祈使句以及when的用法，理解后，本題不難作答．
