Grammar
動(dòng)詞不定式
當(dāng)我們要表示“想做某事、需要做某事或決定做某事”時(shí)，就會(huì)出現(xiàn)兩個(gè)動(dòng)詞連用的情況，這時(shí)應(yīng)如何表達(dá)呢？
同學(xué)們自然會(huì)想到want to do sth.,need to do sth.和decide to do sth.等表達(dá)方式。
1. 什么是動(dòng)詞不定式？
主要行為動(dòng)詞后面的動(dòng)詞都采用了“to+動(dòng)詞原形”的結(jié)構(gòu)，我們把這種結(jié)構(gòu)稱(chēng)為動(dòng)詞不定式（有時(shí)可以不帶to）。動(dòng)詞不定式?jīng)]有人稱(chēng)和數(shù)的變化，在句子中不能作謂語(yǔ)。下面我們一起來(lái)看一下動(dòng)詞不定式有哪些語(yǔ)法功能。
2. 動(dòng)詞不定式的語(yǔ)法功能：
1. 不定式作主語(yǔ)
不定式作主語(yǔ)時(shí)，常用it作形式主語(yǔ)，而將作主語(yǔ)的不定式放在句子后部。
eg.
It is good to help others.
幫助他人是件好事。
It is exciting to surf the Internet.
上網(wǎng)是件令人興奮的事。
2. 不定式作賓語(yǔ)
學(xué)習(xí)不定式作賓語(yǔ)時(shí),要注意掌握:后接不定式作賓語(yǔ)的動(dòng)詞。常見(jiàn)動(dòng)詞有: want,
hope, wish, like, begin, try, need, forget, agree, help 等。
Many people decide not to think about it.
許多人決定不去想這件事。
I want to go to the library.
