【答案】

1.happier2.whose3.themselves4.integrating5.If6.wassubmitted7.given

8.could9.within10.why

【導(dǎo)語】本文是一篇新聞報(bào)道。文章主要報(bào)道了三個(gè)好朋友Fatima,Julia,和Felipe積極參加編程競賽，

以獲得精英中學(xué)的入學(xué)資格。

1.考查形容詞。句意：因此，她再高興不過了。句型：can'tbe+形容詞比較級，意為"再......也不過分"。

故填happier。

2.考查定語從句。句意：4C挑戰(zhàn)賽（也被稱為克拉克縣編程比賽）是今年的活動(dòng)，目標(biāo)參與者是有stem

思維的八年級學(xué)生，比如和她的兩個(gè)最好的朋友和考查定語從句的關(guān)

FatimaJuliaSheenFelipeAlvarezo

系詞，先行詞為"theevent",和"target”之間為所有關(guān)系，用whose。故填whose。

3.考查代詞。句意：同學(xué)們忙著在社交媒體上曬自己暑假的照片，而這三個(gè)自稱"Java時(shí)間團(tuán)隊(duì)”的好朋友

花了無數(shù)個(gè)小時(shí)制作故事板、編碼和調(diào)整程序。指代主語，用反身代詞；主語為who,指的是"thethreebest

friends”,用themselves。故填themselves。

4.考查非謂語動(dòng)詞。句意：他們的應(yīng)用程序《羅密歐與朱麗葉混音版》將這部著名的戲劇變成了一款多

人冒險(xiǎn)游戲，將莎士比亞的語言與歌曲的押韻結(jié)合在一起，重新講述了這個(gè)故事。這里為非謂語動(dòng)詞擔(dān)當(dāng)

狀語，和主句主語"theirapp”之間為主動(dòng)關(guān)系,用動(dòng)詞ving形式。故填integrating。

5.考查狀語從句。句意：如果在任何時(shí)候他們失去了動(dòng)力，他們就會(huì)受到NeilGreen每周發(fā)來的短信的推

動(dòng)，他今年接管了競爭協(xié)調(diào)工作。這里為狀語從句的連接詞，根據(jù)句意可知，空處指的是"如果"，用if引

導(dǎo)；出現(xiàn)在句首，首字母大寫。故填I(lǐng)f。

6.考查時(shí)態(tài)和語態(tài)。句意：當(dāng)他們的應(yīng)用程序被提交到競賽的提交網(wǎng)站時(shí)，F(xiàn)atima說："獲獎(jiǎng)固然很好，

但我們都知道最好的獎(jiǎng)勵(lì)是什么。"這里為從句謂語動(dòng)詞，根據(jù)時(shí)間狀語"ontheday"可知，從句時(shí)態(tài)為一

般過去時(shí)；主語為theirapp,單數(shù)，和動(dòng)詞submit之間為被動(dòng)關(guān)系，所以用被動(dòng)語態(tài)。故填wassubmitted。

7.考查非謂語動(dòng)詞。句意：Fatima,Julia,和Felipe很興奮地在其他八年級學(xué)生面前展示他們的數(shù)字技能，

但他們最感興趣的是給前三名的獎(jiǎng)勵(lì)：保證進(jìn)入凱瑟琳約翰遜高中，這是該縣的STEM精英中學(xué)。這里為

非謂語動(dòng)詞擔(dān)當(dāng)后置定語，動(dòng)詞"give"和被修飾詞"thereward"之間存在被動(dòng)關(guān)系，用動(dòng)詞的過去分詞。故

填giveno

8.考查情態(tài)動(dòng)詞。句意：Felipe,Fatima,和Julia從幼兒園開始就是朋友，他們幾乎不能抑制自己的興奮。

根據(jù)句意可知，三個(gè)好朋友決定勝利在望，所以不能抑制自己的興奮，用情態(tài)動(dòng)詞could。故填could。

9.考查介詞。句意：他們一起去KJHS的夢想就在眼前！固定短語：withinone7sreach,意為"伸手可及"。

故填withino

10.考查表語從句。句意：這就是為什么Fatima不介意在這個(gè)寒冷的11月周六早上8點(diǎn)起床，去克拉克

斯維爾大學(xué)度過一天的原因，那里是一年一度的比賽的舉辦地。這里為表語從句的連接詞，根據(jù)句意可知,

表語從句缺少原因狀語，用why引導(dǎo)。故填why。

參考答案：

1.D

【詳解】考查情態(tài)動(dòng)詞。句意：我不知道他怎么敢對老師說那種話。dare是情態(tài)動(dòng)詞，它的過去式是dared,

后接動(dòng)詞原形。dared作行為動(dòng)詞時(shí)，要用daretodosth.,行為動(dòng)詞有數(shù)的變化，這句話的主語是he,其

謂語的正確形式應(yīng)該是darestosay,因此D選項(xiàng)正確，故選D。

2.C

【詳解】考查情態(tài)動(dòng)詞。句意：今天早上我排隊(duì)等了很長時(shí)間才買下這張票，我感到很后悔。我本來可以

在網(wǎng)上買的。couldhavedone表示過去本來可以有機(jī)會(huì)選擇做某事，但實(shí)際上沒有那樣做，通常譯為“本來

可以"。故選C。

【點(diǎn)睛】情態(tài)動(dòng)詞+havedone是我們要學(xué)習(xí)的情態(tài)動(dòng)詞中重要的一個(gè)語法項(xiàng)目，有一點(diǎn)是大家必須記住的，

那就是——它一定表示“過去的或已經(jīng)發(fā)生的事情”。

下面帶大家逐一總結(jié)一下其用法：l、musthavedone對過去的推測，“一定已經(jīng)，肯定已經(jīng)...”；2、can，t/couldn，t

havedone對過去的推測，“不可能做過某事"；3、can/couldsb.havedone...?對過去的推測，“某人可能做過

某事嗎？"4、may/mighthavedone對過去的推測，”也許已經(jīng)，可能做過"；5、needn'thavedone"不必做但

是做了"；6、couldhavedone（不是can）表示“本來可以做而未做"；7、should/oughttohavedone表示“過去

應(yīng)該做卻沒有做"，should/oughtnottohavedone表示“過去不該做但做了"；8、wouldhavedone表示“本打

算做事實(shí)上未做”。

分析本題，抓住兩點(diǎn)：第一、分析句意可知，此處的推測為對過去事情的推測，故用完成式，排除答案A、

B；第二、再分析musthavedone和couldhavedone的區(qū)別，從而選擇出正確的答案。

3.C

【詳解】考查固定結(jié)構(gòu)。句意：——我剛才在老師辦公室看見莉莉了。——你不可能見過她，她回家去了。

A.mustnotsee不準(zhǔn)看見；B.mustn'thaveseen不能看到；C.can'thaveseen不可能做過某事；D.couldn'tsee
