答案：B.
翻譯：他贏得第一名/一等獎(jiǎng),這使得他爸媽很高興.
解釋?zhuān)?br/>1. ____ the first prize必須在句中做主語(yǔ),make為句子謂語(yǔ),his parents為賓語(yǔ),happy為賓語(yǔ)補(bǔ)足語(yǔ),此句是一個(gè)一般過(guò)去時(shí)態(tài)的一般疑問(wèn)句.
2. 所以選用his winning,它和后面的the first prize一起構(gòu)成一個(gè)動(dòng)名詞的復(fù)合結(jié)構(gòu),在句中充當(dāng)主語(yǔ).
動(dòng)名詞復(fù)合結(jié)構(gòu),即在動(dòng)名詞短語(yǔ)前面加上形容詞性物主代詞或名詞所有格形式（做賓語(yǔ)時(shí),也可以加上人稱(chēng)代詞賓格或名詞）,后者為動(dòng)名詞所表示動(dòng)作的邏輯主語(yǔ),當(dāng)然它還是屬于動(dòng)名詞.
再如：Do you mind my/me smoking?
my/me smoking即動(dòng)名詞復(fù)合結(jié)構(gòu),做mind的賓語(yǔ).
My being late made my teacher angry.
my being late也是動(dòng)名詞復(fù)合結(jié)構(gòu),做句子的主語(yǔ).
3. 如果選用he win/won/wins都不行,因?yàn)榇藭r(shí)一個(gè)句子里面出現(xiàn)兩個(gè)謂語(yǔ)(win/made)和兩個(gè)主語(yǔ)（he和he win the frist prize）.
不過(guò),可以在he前面加上that,即可以寫(xiě)成：
Did that he had won the first prize make his parents happy?
此時(shí),that he had won the first prize為that引導(dǎo)的主語(yǔ)從句,充當(dāng)主句的主語(yǔ),且此引導(dǎo)詞that不可以省略.
主語(yǔ)從句使用過(guò)去完成時(shí)had won,因?yàn)閣in the first prize發(fā)生在make his parents happy之前.
