Answer:C

Explanation:本题考查定语从句的关系词。题干的意思是：“这本书，_____封面是闪亮的，花了50元。”分析句子结构可知，逗号前为主句，逗号后为非限制性定语从句，修饰先行词“Thebook”，且定语从句中缺少定语修饰先行词“cover”，所以可判断出空白处要填写一个关系代词，作为非限制性定语从句的引导词。选项A，“which”在定语从句中是一个关系代词，通常指代前面提到的整个句子或句子中的某个名词性成分，并在从句中充当主语、宾语或表语，但在此句中，我们需要一个关系代词来修饰“cover”，而不是指代整个句子或“book”，所以“which”不适合。选项B，“its”是形容词性物主代词，意为“它的”，不能用于引导定语从句，故排除。选项C，“whose”在定语从句中是一个关系代词，用于指代人或物的所有格，即“…的”，在此句中，“whose”修饰“cover”，表示“这本书的封面”，符合语境。选项D，“ofwhich”可以引导非限制性定语从句，但需要在“of”后接名词或代词，表示所属关系，而本句“cover”为名词，且前已有“Thebook”的指代，无需再用“ofwhich”来强调所属关系，故排除。4、_____Iamstandingisafamoussquare,wheremanyhistoricaleventstookplace.A.ThatB.WhereC.WhichD.Theplacewhere

Answer:D

Explanation:本题考查名词性从句的引导词。题干的意思是：“_____我正站的地方是一个著名的广场，许多历史事件在那里发生。”分析句子结构可知，“_____Iamstanding”为“is”的主语从句，且此主语从句中缺少地点状语，所以空白处需要选择能引导主语从句且能在从句中作地点状语的词。选项A，“That”引导名词性从句时，在从句中无具体含义，只起连接作用，而且在从句中也不作任何句子成分，它所引导的从句的句子结构和意义是完整的，但在此题中，从句缺少地点状语，所以“That”不适合。选项B，“Where”引导名词性从句时，相当于“theplacewhere”，意思是“……的地方”，但在本句中，如果选“Where”，则从句缺少主语，所以“Where”不适合。选项C，“Which”引导名词性从句时，在从句中充当成分，意为“……的哪一个”，但在此句中，我们需要一个表示地点的词，而不是“哪一个”，所以“Which”不适合。选项D，“Theplacewhere”中，“Theplace”是名词性短语，可作主语从句的主语，“where”在从句中作地点状语，代入原句表示“我正站的地方”，符合语境。5、Title:GrammarFill-in-the-BlankQuestion:

He________(work)asateacherforfiveyearsbeforehemovedtoLondon.Answer:hadworkedExplanation:Thesentencereferstoanactionthatoccurredbeforeanotherpastaction(movingtoLondon).ThisindicatestheuseofthePastPerfectTense,whichisformedby“had”+thepastparticipleoftheverb.“Work”inthepastparticipleformis“worked,”thusmakingthecompleteform“hadworked.”6、Title:GrammarFill-in-the-BlankQuestion:

Theconcert________(start)at8p.m.sharp,soweshouldarriveearly.Answer:startsExplanation:Thesentencedescribesageneralfactorhabit,whichinEnglishisusuallyexpressedintheSimplePresentTense.Here,“Theconcertstartsat8p.m.sharp”indicatesaregularorscheduledevent,notapast,future,orcompletedaction.Thus,theverb“start”remainsinitsbaseform“starts.”7、Theoldmanwasseen_______(walk)intotheparkjustnow.

Answer:walking

Explanation:Thephrase“wasseen”indicatesapassiveformoftheverb“see”,whichisoftenusedwiththeinfinitiveformoftheverbbutwith“to”omittedinthepassivevoice.Inthiscontext,“walk”isanactionthatwasbeingobservedhappeningatthetimeofbeingseen,soweusethepresentparticipleform“walking”toexpressthiscontinuousorongoingaction.8、Itisthefirsttimethatwe_______(visit)theGreatWall.

Answer:havevisited

Explanation:Thephrase“Itisthefirsttimethat…”isacommonstructureinEnglishthatrequiresapresentperfecttenseverbformtoindicatethattheactionmentionedhasalreadyoccurredandisbeingcountedasafirstoccurrence.Inthiscase,“wehavevisited”indicatesthattheactionofvisitingtheGreatWallhasalreadyhappened,andthisisthefirsttimeithasoccurred.9、______Iwasverytired,Iwentonworking.A.AlthoughB.SoC.IfD.Because
