一、連系動(dòng)詞基本用法

連系動(dòng)詞是表示不完全謂語關(guān)系的動(dòng)詞，它與其后的表語一起構(gòu)成謂語。常見的連系動(dòng)詞有be(是)，become(成為)，get(變成)，remain(還是)，seem(似乎是)，look(看上去)，feel(感覺)等。連系動(dòng)詞后的表語通常是名詞和形容詞，有時(shí)也可以是代詞、數(shù)詞、副詞、介詞短語、不定式、動(dòng)名詞、從句等：

His English is excellent. 他的英語很棒。(跟形容詞)

He is a famous poet. 他是著名詩人。(跟名詞)

Money isn’t everything.金錢不是一切。(跟代詞)

She was the first to arrive.她是第一個(gè)到達(dá)的人。(跟數(shù)詞)

Who is upstairs? 誰在樓上?(跟副詞)

He is with his friends. 他和朋友在一起。(跟介詞短語)

He seems to be ill. 他似乎病了。(跟不定式)

Seeing is believing. 眼見為實(shí)。(跟動(dòng)名詞)

This is what you need. 這就是你需要的。(跟從句)

二、學(xué)習(xí)連系動(dòng)詞應(yīng)注意的兩點(diǎn)

誤：His English is very well. 他的英語很好。(應(yīng)將well改為good)

誤：Be carefully. 小心點(diǎn)。(應(yīng)將carefully改為careful)

誤：The soup tastes nicely. 這湯味道不錯(cuò)。(應(yīng)將nicely改為nice)

但是，有時(shí)連系動(dòng)詞后也可接副詞作表語，不過這主要限于in, on, off, out, away, behind, up, down, over, through, around, round, below, inside, outside 等少數(shù)副詞小品詞以及here, there, upstairs, downstairs等少數(shù)表示地點(diǎn)或方位的副詞：
