【即學即練】Itdoesn’tmatter_____youturnrightorleftatthecrossing—bothroadsleadtothepark.A.whetherB.howC.ifD.when【解析】選A?？疾槊~性從句。句意：在十字路口，無論你是向右拐還是向左拐，都沒關(guān)系——這兩條路都通向公園。分析空格后面的成分可知該部分不缺成分，排除在句中需作狀語的B、D；又因it為形式主語，matter后面的部分為真正的主句，即為主語從句；并且if（是否）不能引導名詞性從句，所以排除C，選A。

主語從句三要素hebecameagreatscientistisknowntousall.whatyoutoldmeistrue.謂語動詞一般用單數(shù)從句用陳述語序不能省略關(guān)聯(lián)詞How

【常見錯誤展示】

下列各句均有一處錯誤，請改正并分析錯誤的原因。1.Lighttravelsfasterthansoundiscommonknowledge.2.Ifshe’scomingornotdoesn’tmattermuch.Thatthat雖無詞義但引導主語從句位于句首時不能省略。if,whether都可表示“是否”,但if不能引導位于句首的主語從句，它可以引導后置的主語從句。Whether3.Thattheprofessorsaidisofgreatimportance.4.Wherewillthetreesbeplantedhasnotbeendecided.

that引導主語從句時無詞義。Whattheprofessorsaid表示“教授所說的”。將will置于trees之后。主語從句要用陳述語序。What5.Nomatterwhobreakstherulewillbepunished.6.Whenandwherethemeetingwillbeheldstillremainaquestion.引導讓步狀語從句時二者可互換，但引導名詞性從句時只能用whoever。主語從句表示單一概念時，謂語要用單數(shù)形式。Whoeverremains
