thenumberof與anumberof的辨析(1)thenumberof是固定短語(yǔ),意為“……的數(shù)量”,后接可數(shù)名詞復(fù)數(shù),但中心詞是number,所以謂語(yǔ)動(dòng)詞要用單數(shù)。(2)anumberof為量詞短語(yǔ),意為“許多;大量”,相當(dāng)于alotof或lotsof,中心詞是該短語(yǔ)所修飾的可數(shù)名詞復(fù)數(shù),所以作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞用復(fù)數(shù)形式?！炯磳W(xué)活用】①-Anumberofvolunteers______willingtoteachinChina’sruralareas.—Yes,thenumberisgetting______.A.is;biggerandbiggerB.are;biggerandbiggerC.is;moreandmoreD.aremoreandmore【解析】選B?？疾橹髦^一致和形容詞比較級(jí)的用法。anumberof...作主語(yǔ),謂語(yǔ)動(dòng)詞使用復(fù)數(shù)形式,排除A、C;第二個(gè)空表示“數(shù)量在變得越來(lái)越多”,故選B。②(2015·益陽(yáng)中考)—Howmanywomendoctorsarethereinyourhospital?—______them______overtwenty.A.Anumberof;areB.Thenumberof;areC.Thenumberof;is【解析】選C?？疾槎陶Z(yǔ)辨析和主謂一致。thenumberof“……的數(shù)量”,謂語(yǔ)動(dòng)詞用單數(shù);anumberof“大量的,許多”,謂語(yǔ)動(dòng)詞用復(fù)數(shù)。句意:——你們醫(yī)院有多少名女醫(yī)生?——她們的數(shù)量是超過(guò)二十個(gè)。故選C?？键c(diǎn)2aswell還;也*Peoplehavecutdownalotoftreesaswell.人們還砍伐了許多樹(shù)木。*IwritemyownsongsandIplaytheguitaraswell.我自己作曲,也彈吉他?！咀灾鳉w納】

aswell常用作狀語(yǔ),作“又;也”解,相當(dāng)于too或also,一般位于句末,不用逗號(hào)與句子分開(kāi)?！久畋娈愅?/p>

“也”的不同表達(dá)含義用法also也,還常用在肯定句或疑問(wèn)句中,放在行為動(dòng)詞前,be動(dòng)詞或助動(dòng)詞后。例如:HeisgoodatEnglish.HeisalsogoodatJapanese.他擅長(zhǎng)英語(yǔ),也擅長(zhǎng)日語(yǔ)。含義用法too也常用在肯定句句末,其前一般用逗號(hào)隔開(kāi)。例如:HestudieshardandIstudyhard,too.他學(xué)習(xí)用功,我學(xué)習(xí)也用功。either也常用在否定句句末,其前加逗號(hào)。例如:Ifyoudon’tgoshopping,Iwon’t,either.如果你不去購(gòu)物,我也不去。含義用法aswell也,同樣地與too在句中的位置相同,兩者可以互換,但aswell前不加逗號(hào),通常位于句末。例如:Icandoitaswell.這件事我也能做?！就卣寡由臁?/p>

aswellas常用來(lái)連接兩個(gè)并列的成分,作“也,還”講時(shí),它強(qiáng)調(diào)的是前一項(xiàng),后一項(xiàng)只是順便提及。因此連接并列主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞與前一項(xiàng)一致;而notonly...butalso...連接并列主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞與后一項(xiàng)一致。例如:Yourwifeaswellasyouisfriendlytome.不僅你而且你的妻子也對(duì)我很友好。(=Notonlyyoubutalsoyourwifeisfriendlytome.)【即學(xué)活用】選詞填空(also/too/either/aswell)。①I____likeplayingtheviolin.②Mybrotherdoesn’teatvegetables,_____.③HewenttoBeijingtovisittheGreatWall,___.④Mymotherisateacher______.

beginning的其他搭配(1)inthebeginning意為“起初”。例如:Idislikedthisdoginthebeginning.起初我不喜歡這只狗。(2)frombeginningtoend意為“從頭到尾”。例如:Ihavereadthisbookfrombeginningtoend.我從頭到尾讀了這本書?！炯磳W(xué)活用】①上個(gè)月初下了很多雨。Wehadmuchrain________________lastmonth.②吉姆從一開(kāi)始就在公共汽車上。Jimwasonthebus_________________.
