1.Maybeyoushouldmaketheholealittlebigger.

也許你應(yīng)該讓洞更大一點(diǎn)。

maybe

作副詞，意思是“也許；大概”，在句中作狀語(yǔ)，一般放在句首，可以位于句中，還可以單獨(dú)作答語(yǔ)?！就卣埂縨aybe是由“情態(tài)動(dòng)詞may+動(dòng)詞原形be”構(gòu)成的，在句中作謂語(yǔ)，意思是“可能是”。Itmaybeinyourbag.

它可能在你包里。知識(shí)精講

alittlebigger

意為“大一點(diǎn)”。alittle

在此作程度副詞,可用于修飾形容詞、副詞的比較級(jí),表示比較的程度。Sheisalittletallerthanhersister.她比她的姐姐高一點(diǎn)?！就卣埂砍薬little之外,

much,

alot,

even,

far等都可以修飾比較級(jí)。Shedidmuchbetterthistime.她這次做得好多了。(2018年湖南長(zhǎng)沙中考)—Dothetwinslookthesame?—No,Janeis_____tallerthanClaire.A.littleB.more C.alittle【點(diǎn)撥】考查形容詞比較級(jí)的修飾詞。句意：——這對(duì)雙胞胎看起來(lái)一樣嗎？——不，簡(jiǎn)比克萊爾更高一點(diǎn)。修飾比較級(jí)的詞有：much,alot,far,alittle,abit,still,even,故選C。C典例知識(shí)精講

2.Itmustbelargeenoughtoholdtherootsoftheseeding.

它必須足夠大以容納種子的根。

must是情態(tài)動(dòng)詞，意為“必須；肯定”。也可以表示推測(cè)。用在肯定句中表示較有把握的推測(cè)。對(duì)現(xiàn)在的狀態(tài)或現(xiàn)在正發(fā)生的事情的推測(cè)時(shí)，must后面通常接系動(dòng)詞be的原形或行為動(dòng)詞的進(jìn)行式。如：Youhaveworkedhardallday.Youmustbetired.你辛苦干一整天，一定累了。（2018年山東青島中考）Thisbook______beLucy’s.Look!Hernameisonit.A.canB.mayC.mustD.might【點(diǎn)撥】考查情態(tài)動(dòng)詞表推測(cè)的用法。句意：這本書一定是露西的?？?，她的名字在上面。can表示推測(cè)時(shí)，通常只用于否定句或疑問(wèn)句；may和might表示推測(cè)的可能性較小。由“Hernameisonit”可知，把握非常大，這本書“一定”是她的。故選C。C典例知識(shí)精講3.Now,puttheseedlinginside,covertherootsandfill

theholewithdirt.

現(xiàn)在，把幼苗放進(jìn)來(lái)，蓋上根，用泥土填上坑。cover/?k?v?/v.

覆蓋n.

蓋子；封面如：Shecoveredherfacewithherhands.她雙手掩面。Thebookneedsanewcover.這本書需要一個(gè)新封面。知識(shí)精講becoveredwith被……覆蓋如：Theroadisusuallycoveredwithsnow.這條路通常被雪覆蓋。魔法記憶一語(yǔ)辨異：Sheusedacovertocoverabox.她用一個(gè)蓋子蓋一個(gè)箱子。知識(shí)精講4.Now,puttheseedlinginside,covertherootsandfillthe

holewithdirt.

現(xiàn)在，把幼苗放進(jìn)來(lái)，蓋上根，用泥土填上坑。

fill

作動(dòng)詞，常用動(dòng)詞詞組

fill…with…，

意為“用……把……裝滿”。被動(dòng)形式：

befilledwith意為“裝/填滿……”，相當(dāng)于befullof，full是形容詞。如：Hefilledhisbackpackwithbooks.他把書裝進(jìn)書包。知識(shí)精講5.Bytheway,

thereisanothergroupofpeopledownthehill.順便說(shuō)一下，在山下還有一組人。bytheway意為“順便問(wèn)一下;順便說(shuō)一下”，表示附帶說(shuō),常用于交談中引出題外的話語(yǔ)。通常放在句首，用逗號(hào)將其與后面的句子隔開(kāi)。Bytheway,

whattimeisit?順便問(wèn)一句，現(xiàn)在幾點(diǎn)了?【拓展】由way構(gòu)成的其他短語(yǔ):(1)intheway妨礙Thereweresomebigstonesintheway.

有一些大石頭擋住了路。(2)inthisway用這種方法Iworkedoutthisprobleminthisway.

我用這個(gè)方法解決了問(wèn)題。(3)ontheway即將到達(dá)Thespringisontheway.春天即將到來(lái)。(4)inoneway在某種程度上。Inoneway,Iagreewithher.

在某種程度上，我同意她的觀點(diǎn)。知識(shí)精講turninto意為“變成”,相當(dāng)于growinto,其中into是介詞,后接名詞或代詞作賓語(yǔ)。turnsb/sthintosth意為“把……變成……”。Thewitchturnedtheprinceintoafrog.女巫把王子變成了青蛙?！就卣埂亢衪urn的短語(yǔ):

turnin交還;turnout出席;

turnover翻身;turnup露面。6.Alotofrichlandsinthenorthernareahaveturnedintodesert.在北方地區(qū)許多肥沃的土地變成了沙漠。知識(shí)精講知識(shí)精講7.Isupposetreeplantingisveryimportantwork.

我想，植樹(shù)造林是非常重要的工作。suppose是及物動(dòng)詞，常用來(lái)表示說(shuō)話人的看法、猜測(cè)或假設(shè)。其基本用法如下：(1)

“suppose＋名詞/代詞＋介詞短語(yǔ)”

表示

“猜測(cè)某人/某物在……”。如：Hesupposedhisfriendinthelibrary.他猜想他的朋友在圖書館里。知識(shí)精講(2)besupposedto中的to是動(dòng)詞不定式符號(hào)，后接動(dòng)詞原形，主語(yǔ)為人時(shí)，表示“應(yīng)該；被期望”，它可以用來(lái)表示勸告、建議、義務(wù)、責(zé)任等。主語(yǔ)為物時(shí)，它表示“本應(yīng)；本該”，用于表示某事本應(yīng)該發(fā)生而沒(méi)有發(fā)生。它還可以用來(lái)表示“被認(rèn)為是；被相信是”。如：Iamsupposedtostartworkat7:30everymorning.

我理應(yīng)每天早晨7:30開(kāi)始工作。知識(shí)精講8.It’sfunandimportanttoplantplants.

種植物既有趣又重要。It’s+adj.+(forsb.)todosth.（對(duì)某人來(lái)說(shuō)）做……是……的。it作形式主語(yǔ)，真正的主語(yǔ)是后面的動(dòng)詞不定式。其中sb.是動(dòng)詞不定式todo的邏輯主語(yǔ)。It’sdangerousforchildrentoplaywithfire.對(duì)孩子們而言，玩火是危險(xiǎn)的。
