小升初英語(yǔ)語(yǔ)法祈使句知識(shí)點(diǎn)：不要混淆祈使句與非謂語(yǔ)動(dòng)詞
　　有這樣一道語(yǔ)法考題，該用動(dòng)詞原形？還是用非謂語(yǔ)動(dòng)詞？
　　_________ the road round to the right and you’ll find his house.
　　A. Follow B. Following C. To follow D. Followed
　　【分析】此題容易誤選B或C，許多同學(xué)一看選項(xiàng)就想當(dāng)然地認(rèn)為，選現(xiàn)在分詞表示時(shí)間或伴隨，選不定式表目的。此題的關(guān)鍵是要注意句中的連詞and，它表明整個(gè)句子是一個(gè)并列句，即 and 前后應(yīng)各是一個(gè)獨(dú)立的句子，而不應(yīng)是一個(gè)非謂語(yǔ)形式的短語(yǔ)，所以此題的正確答案應(yīng)選A，即 and 前是一個(gè)祈使句。比較以下兩題：
　　(1) _________ the road round to the right， she found his house.
　　A. Follow B. Following C. To follow D. Followed
　　【分析】此題應(yīng)選B，現(xiàn)在分詞短語(yǔ)表時(shí)間。
　　(2) _________ the road round to the right， the blind man asked a boy to guide him.
　　A. Follow B. Following C. To follow D. Followed
　　【分析】此題應(yīng)選C，不定式短語(yǔ)表目的。
