不，它們不是。含be動詞的一般疑問句的結構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，對其回答時用降調。本單元我們學習的是含有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，則應把第一人稱變?yōu)榈诙朔Q，be動詞也要作出相應的變化；如果有形容詞物主代詞my，也應改為your。三問號：將句末的標點符號改為問號。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
