It is good to help others. 帮助他人是好的。 It is exciting to surf the Internet. 上网是令人兴奋的。 (2) 不定式作宾语 学习不定式作宾语时,要注意掌握后接不定式作宾语的动词。常见动词有: want, hope, wish, like, begin, try, need, forget, agree, help 等。 Many people decide not to think about it. 许多人决定不去考虑这件事。 I want to go to the library. 我想去图书馆。 (3) 不定式作定语 不定式修饰名词或代词，起形容词的作用，在句中作定语，放在被修饰对象的后面。请看下列句子： I have a lot of homework to do. 我有很多作业要做。 I’m hungry. Give me something to eat, please. 我饿了。请给我点吃的吧。 (4) 不定式作状语 不定式常常作目的状语、原因状语、结果状语等。不定式作状语时，要注意不定式的逻辑主语应与句子的主语保持一致。 I came to Beijing to see my grandpa. 我来北京看望我的爷爷。 I’m glad to meet you！很高兴见到你！ I’m too tired to walk. 我太累了，走不动了。 (5) 不定式作补足语 不定式可以作补足语。例如： She told me to buy a ticket. 她让我去买张票。 (6) 不定式作表语 不定式还可以作表语。例如： Our duty today is to clean the floor. 今天我们的任务是打扫地板。 1.
