Is this表示詢(xún)問(wèn)所以be動(dòng)詞在前例如This is my book.【這是我的書(shū)】疑問(wèn)為Is this your book?【這是你的書(shū)嗎】,因?yàn)檫@句話中的‘is’表單數(shù),所以‘book’是單數(shù).相同的‘a(chǎn)re’是表復(fù)數(shù),當(dāng)然在第二人稱(chēng)‘you’的時(shí)候也用‘a(chǎn)re’.如Who are you?值得一提的是,詢(xún)問(wèn)對(duì)方名字的時(shí)候是‘what is your name’用的是‘is’
that指‘那個(gè)’is that與is this用法差不多.
thoes是‘那些’,因?yàn)椤切硎緩?fù)數(shù)所以要用be動(dòng)詞are
例句
she is my sister.
these are oranges【orange加‘s’表示復(fù)數(shù),多數(shù)名詞有復(fù)數(shù)通常加-s,es,ies,ves等,根據(jù)首字母音標(biāo)變化加復(fù)數(shù).也有‘不可數(shù)’,是不加s的,不可數(shù)名詞都是單數(shù),如hair等
Is that your friend?
