B．Turnsouttobe.C．Mainlyresultsfrom.D．Suggeststhesuccessof.答案：D解析：詞義揣測題。畫線短語所在的句子意思是天宮二號的勝利放射，以及中國新一代運(yùn)載火箭長征七號的首次放射，勝利預(yù)示了中國載人航天三步走安排進(jìn)入最終階段。由此可知“bodeswellfor”意思是“很好地表明”，故選D。3．Whatisthebesttitleforthetext?A．OneStepClosertoTiangong-2 B．3StepsofChina'sSpacePlanC．China'sSpaceLabLaunched D．SpaceStation,China'sDream答案：C解析：標(biāo)題推斷題。第一段中ChinasuccessfullylaunchedspacelabTiangong-2intospace,meaninganotherhistoricsteptowardsbuildingamannedspacestationaround2024.是全文的主題句，結(jié)合全文內(nèi)容，可知這篇文章主要講了中國勝利將天宮二號空間試驗(yàn)室送入太空，這意味著中國朝著2024年左右建成載人空間站又邁出了歷史性的一步。故選C。Ⅱ.七選五FivestepstobetterhandwritingSomekidslovehandwriting,butothershateitwhenit'stimetoputpentopaper.Maybetheyareworriedabouttheirhandwriting.Areyouoneofthem?__1__Herearefivestepsthatreallywork!GetagreatgraspTrythis—holdyourpencilatthetopandtrytowriteyourname.Prettyhard?Butwhenyouholdyourpencilthecorrectway,writingismucheasier.__2__Holditinplacewithyourthumb(拇指),andyourindexandmiddlefingers.LetthelinesbeyourguideLinedpaperisyourfriend!Thoselinescanhelpyoucreatelettersthatareoftherightsizeandproportion(比例).__3__Alsobesuretofillupthelinedspacecompletely.Thosecapitallettersshouldbefromthebottomlinetothetopone.SlowdownIfyourwritingishardtoread,tryslowingdownalittle.Ifyourush,it'shardtocontrolwhereyoustopandstartyourletters.Lowerthepressure(壓力)__4__Thatmakesithardertomakethesmoothlines.Tryrelaxinganddon'tholdthepenciltoohard.__5__Lotsofgamesneedyoutowriteordrawpictures.Soeventhoughit'snotschoolwork,you'restillusingtheskillsyouneedtocontrolyourpencilbetter.A．PlaygamesB．AskforadviceC．You'vebeenwritingsinceyouwerealittlekid.D．So“a”shouldbehalftheheightofacapital“A”．E．Somekidspressdownreallyhardwhentheywrite.F．Thebestwaytoholdapencilistorestitnexttothebaseofyourthumb.G．Thegoodnewsisthatjustabouteveryonecanimprovetheirhandwriting.這是一篇說明文。短文介紹了提高書寫質(zhì)量的五個步驟。1．G解析：由“Maybetheyareworriedabouttheirhandwriting.Areyouoneofthem?__1__Herearefivestepsthatreallywork！”可知，或許他們擔(dān)憂自己的書寫。你是他們中的一員嗎？這里有五個真的很有用的步驟。所以小題1要起到承上啟下的作用。故G選項(xiàng)“好消息是，幾乎每個人都可以提高他們的書寫”切題。故選G項(xiàng)。2．F解析：由“Holditinplacewithyourthumb(拇指),andyourindexandmiddlefingers.”可知，用拇指、食指和中指將其固定到位。所以小題2與后一句一同來說明如何正確地拿筆。故F選項(xiàng)“拿鉛筆最好的方法是讓它靠在拇指上”切題。故選F項(xiàng)。3．D解析：由“Thoselinescanhelpyoucreatelettersthatareoftherightsizeandproportion(比例)”可知，這些線條可以幫助寫出大小和比例合適的字母。所以小題3要舉例說明這些線在書寫時的作用。故D選項(xiàng)“所以‘a(chǎn)’應(yīng)當(dāng)是大寫字母‘A’的一半高”切題。故選D項(xiàng)。4．E解析：由“Thatmakesithardertomakethesmoothlines”可知，這樣就很難寫出平滑的線條。所以小題4要說明哪種狀況導(dǎo)致很難寫出平滑的線條。故E選項(xiàng)“有些孩子寫字的時候很用力”切題。故選E項(xiàng)。5．A解析：由“Lotsofgamesneedyoutowriteordrawpictures.Soeventhoughit'snotschoolwork,you'restillusingtheskillsyouneedtocontrolyourpencilbetter”可知，很多嬉戲都須要你去寫或者畫畫。所以即使這不是作業(yè)，你仍舊在運(yùn)用你須要的技能來更好地限制你的鉛筆。所以本段主要在說明玩嬉戲也可以幫助你提高書寫質(zhì)量，也就是小題5本段的標(biāo)題所要說明的內(nèi)容。故A選項(xiàng)“玩嬉戲”切題。故選A項(xiàng)。Ⅲ.語法填空Nowadays,millions__1__lonelysinglesarenowgoingonlineinstead.TheWorldWideWebisquicklybecoming__2__world'smostpopularmatchmaker(媒人)．Singlesareflocking(涌向)totheInternet__3__(main)becausetheirbusylifestylesleavethemlittletimetolookforasignificantother.Usingdatingsites(約會網(wǎng)址)isquickandconvenient.Manysinglessaytheregulardatingscene__4__(justlead)themfromonebadexperienceto__5__andarereadytotrysomethingelse.Datingsitesalsomake__6__easytoavoidsomeone__7__youarenotinterestedin.Intherealworld,__8__，ignoringsomeoneyoudon'tlikecanbedifficult.Despitealltheadvantages,onlinedatingalsopresentsitsownsetofproblems.Peoplearen'talwaysthosewhotheydeclaretobeintheironline__9__(describe).Safetyisanotherconcern.Youarejust__10__(like)tofindacriminalonlineasyourMrorMissRight.本文為記敘文。文章主要介紹了網(wǎng)絡(luò)交友方面的問題，并提出了平安方面的建議。1．of解析：考查介詞。句意：現(xiàn)在，數(shù)以百萬計(jì)的孤獨(dú)的人在上網(wǎng)。millionsof“數(shù)以百萬的，成千上萬的”是固定用法，表示概數(shù)，故填of。2．the解析：考查冠詞。句意：網(wǎng)絡(luò)正在快速成為世界上最受歡迎的媒人。最高級前應(yīng)加定冠詞the，故填the。3．mainly解析
