03易錯題通關(guān)

易錯陷阱1：主語從句連接詞what/that/whether/if易混易錯點(diǎn)。

【分析】1.that引導(dǎo)主語從句時(shí)，無詞義，只起連接作用，一般不能省略。what在從句中作主語、賓語、

表語和定語。

2.whether引導(dǎo)的主語從句可放在句首，if引導(dǎo)主語從句在句尾，且用it作形式主語。

3.It作形式主語，that引導(dǎo)真正的主語從句。

4.What引導(dǎo)主語從句時(shí)，謂語動詞一般用復(fù)數(shù)形式，若表語是復(fù)數(shù)，則謂語用復(fù)數(shù)。

易錯陷阱2：賓語從句引導(dǎo)詞及介詞后接賓語從句易混易錯點(diǎn)。

【分析】1.doubt用于肯定句時(shí)，賓語從句用whether，doubt用于否定句時(shí)，賓語從句用that引導(dǎo)。

2.介詞后跟賓語從句時(shí)只能用wh-類連接詞引導(dǎo)；如：I’msurprisedatwhathesaid.

3.介詞后如果跟that從句，要先加it作形式賓語，再加that從句。

如：dependonitthat...;relyonitthat...;seetoitthat...等。

4.賓語從句的時(shí)態(tài)：主句是現(xiàn)在時(shí)或?qū)頃r(shí)，從句用句意的各種時(shí)態(tài)。主句是過去時(shí)，從句用

相應(yīng)的過去時(shí)態(tài)。從句表示客觀事實(shí)或真理，從句都用現(xiàn)在時(shí)。

易錯陷阱3：表語從句引導(dǎo)詞及三個(gè)句式易混易錯點(diǎn)。

【分析】1.asif/asthough引導(dǎo)時(shí)，從句可用陳述語氣，也可以用虛擬語氣。

2.Thatiswhy+結(jié)果，表示“那就是.....的原因”。

3.Thatisbecause+原因，表示“那是因?yàn)?.....”。

4.Thereasonwhy/for...isthat...,表示“......的原因是......”。

易錯陷阱4：同位語從句與定語從句易混易錯點(diǎn)。

【分析】同位語從句與定語從句的區(qū)別

(1)定語從句中的that既代替先行詞，同時(shí)以在從句中作某個(gè)成分（主語或賓語），而同位語從句中的that

是連詞，只起連接主句與從句的作用，不充當(dāng)句中任何成分。

(2)定語從句是形容詞性的，其功能是修飾先行詞，對先行詞加以限定，描述定的性質(zhì)或特征；同位語從

句是名詞性的，其功能是對名詞進(jìn)行補(bǔ)充說明。

1)ThenewsthathetoldmeisthatTomwouldgoabroadnextyear.（他告訴我的消息是湯姆明年將出國。）

（第一個(gè)that引導(dǎo)的從句是定語從句，that在從句中作賓語）

2)ThenewsthatTomwouldgoabroadistoldbyhim.（湯姆將出國的消息是他講的。）

（同位語從句，that在句中不作任何成分）

【易錯點(diǎn)提醒一】主語從句引導(dǎo)詞what/that/whether/if易混易錯點(diǎn)

【例1】（安徽省合肥市第一中學(xué)2024-2025學(xué)年高三試題）Buttrulytwistedherheartatthat

time,shesaid,wasthebackwardanddangerouspracticesoflocalmidwivesandthehardshipsfacedbyexpectant

mothersandnewbornsinJiaxian.

易錯分析：謂語動詞判斷錯誤容易易引起句子結(jié)構(gòu)的誤判，兩個(gè)動詞時(shí)需先判斷主句謂語動詞。

【例3】（2025屆遼寧省本溪市高中高三一模試題）Expertsaren’tsureexactlyhowdreamswork,butwhatis

certainistheyarenecessaryforourmentalhealthandthateveryonehasdreams.

易錯分析：表語從句三大易混句式掌握不牢，且句意理解不清。

【例4】（24-25高三上·內(nèi)蒙古赤峰·期中）StoriesspreadquicklyamonghisfriendsTomhadlivedona

desertedislandforoverfivemonthsaftertheshipwreck.

易錯分析：同位語從句經(jīng)常修飾的名詞記憶不牢，而且句子較長容易引起句意理解錯誤。

【變式1】（24-25高三上·江蘇·期中）Thereissomedoubtonedayhumanswillfindcurestodeal
