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

它可能在你包里。知識精講

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,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。Shedidmuchbetterthistime.她這次做得好多了。(2018年湖南長沙中考)—Dothetwinslookthesame?—No,Janeis_____tallerthanClaire.A.littleB.more C.alittle【點(diǎn)撥】考查形容詞比較級的修飾詞。句意：——這對雙胞胎看起來一樣嗎？——不，簡比克萊爾更高一點(diǎn)。修飾比較級的詞有：much,alot,far,alittle,abit,still,even,故選C。C典例知識精講

2.Itmustbelargeenoughtoholdtherootsoftheseeding.

它必須足夠大以容納種子的根。

must是情態(tài)動詞，意為“必須；肯定”。也可以表示推測。用在肯定句中表示較有把握的推測。對現(xiàn)在的狀態(tài)或現(xiàn)在正發(fā)生的事情的推測時(shí)，must后面通常接系動詞be的原形或行為動詞的進(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)動詞表推測的用法。句意：這本書一定是露西的?？?，她的名字在上面。can表示推測時(shí)，通常只用于否定句或疑問句；may和might表示推測的可能性較小。由“Hernameisonit”可知，把握非常大，這本書“一定”是她的。故選C。C典例知識精講3.Now,puttheseedlinginside,covertherootsandfill

theholewithdirt.

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

覆蓋n.

holewithdirt.

現(xiàn)在，把幼苗放進(jìn)來，蓋上根，用泥土填上坑。

fill

作動詞，常用動詞詞組

fill…with…，

意為“用……把……裝滿”。被動形式：

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。知識精講5.Bytheway,

thereisanothergroupofpeopledownthehill.順便說一下，在山下還有一組人。bytheway意為“順便問一下;順便說一下”，表示附帶說,常用于交談中引出題外的話語。通常放在句首，用逗號將其與后面的句子隔開。Bytheway,

whattimeisit?順便問一句，現(xiàn)在幾點(diǎn)了?【拓展】由way構(gòu)成的其他短語:(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)方法解決了問題。(3)ontheway即將到達(dá)Thespringisontheway.春天即將到來。(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。turnsb/sthintosth意為“把……變成……”。Thewitchturnedtheprinceintoafrog.女巫把王子變成了青蛙。【拓展】含有turn的短語:

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。知識精講知識精講7.Isupposetreeplantingisveryimportantwork.

我想，植樹造林是非常重要的工作。suppose是及物動詞，常用來表示說話人的看法、猜測或假設(shè)。其基本用法如下：(1)

“suppose＋名詞/代詞＋介詞短語”

表示

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

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

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