【點(diǎn)撥】由parents可知前面用復(fù)數(shù)，排除B、D。又因them不能作主語，因此答案為C。句意為：——他們是她的父母嗎？——不是，她的(父母)在家里。

不，它們不是。含be動詞的一般疑問句的結(jié)構(gòu)及其答語不可以縮寫成it’s

一般疑問句是在句子中用提問的方式提供一些信息，要求對方用Yes或No回答的疑問句。朗讀一般疑問句時用升調(diào)，對其回答時用降調(diào)。本單元我們學(xué)習(xí)的是含有be動詞的一般疑問句。語法概述Languagepoints含be動詞的肯定句變一般疑問句，可采用“一提、二變、三問號”的方法。一提：指的是將be動詞提到句首，且首字母大寫。二變：把原主語的首字母變成小寫；如果原主語為第一人稱，則應(yīng)把第一人稱變?yōu)榈诙朔Q，be動詞也要作出相應(yīng)的變化；如果有形容詞物主代詞my，也應(yīng)改為your。三問號：將句末的標(biāo)點(diǎn)符號改為問號。Sheisateacher.Issheateacher?IamTony.AreyouTony?Thosearemypens.Arethoseyourpens?Thisisherbook.Isthisherbook?含be動詞的肯定句變一般疑問句Languagepoints表示所有關(guān)系的代詞叫作物主代詞。物主代詞分為形容詞性物主代詞和名詞性物主代詞兩種。物主代詞語法概述
