--What’s this in English?
---_____ a bike.
A.Here isB.It’sC.ItsD.This’
B

試題分析:句意:這個(gè)用英語(yǔ)怎么說(shuō)?它是一輛自行車。it人稱代詞,指代物多用于指單數(shù),表特指。故選B.
點(diǎn)評(píng):It用作實(shí)詞,表達(dá)以下概念:指代前文提到的事物,前文中的this, that;替代前文中的內(nèi)容;指代一位性別不明的小孩或未知的人;指代未指明但談話雙方都知道的那件事;指代時(shí)間、天氣、氣候、距離等自然現(xiàn)。除此之外,It常用作形式主語(yǔ),替代作主語(yǔ)的從句、動(dòng)詞不定式、動(dòng)名詞,而把真正作主語(yǔ)的從句、動(dòng)詞不定式、動(dòng)名詞置于句尾。
