不要混淆祈使句與非謂語動詞有這樣一道語法考題，該用動詞原形？還是用非謂語動詞？theroadroundtotherightandyou’llfindhishouse.A.FollowB.FollowingC.TofollowD.Followed【分析】此題容易誤選B或C,許多同學一看選項就想當然地認為，選現(xiàn)在分詞表示時間或伴隨，選不定式表目的。此題的關(guān)鍵是要注意句中的連詞and,它表明整個句子是一個并列句，即and前后應(yīng)各是一個獨立的句子，而不應(yīng)是一個非謂語形式的短語，所以此題的正確答案應(yīng)選A,即and前是一個祈使旬。比較以下兩題：theroadroundtotheright,shefoundhishouse.A.FollowFollowingfollowB.A.FollowFollowingfollowC.ToD.Followed【分析】此題應(yīng)選B,現(xiàn)在分詞短語表時間theroadroundtotheright,theblindmanaskedaboytoguidehim.A.FollowFollowingfollowB.A.FollowFollowingfollowC.ToD.Followed【分析】此題應(yīng)選C,不定式短語表目的。注意以下各題均應(yīng)選A,均因為句中的并列連詞and(填空句為祈使旬)：themilkandsetagoodexampletotheotherchildren.A.DrinkB.TodrinkC.DrinkingD.Havingdrinkingme,anddon’tjuststandtherelaughing.A.AnswerB.ToanswerC.
