知识梳理
Language points
1. Mario believes it can help him to get his future dream job.
help sb. (to) do sth. 帮助某人做某事； help后的不定式符号to，可以省略。
e.g. Mike called on his sister to help him look for his lost keys.
迈克叫上他妹妹帮助他找钥匙。
2. . …but I want to learn more about how to care for animals. 但是我想学习更多关于如何照顾动物的事。
want to do sth. 想要做某事。to不定式做want的宾语。
e.g. Grandpa wanted to lend us some money to buy a new car.
爷爷想借给我们钱去买一辆新车。
how to care for animals 是复合不定式结构，作介词about宾语。相当于：特殊疑问词+ to不定式，构成复合不定式结构。(how he could care for animals).
e.g. They don’t know where to build the new house.
=They don’t know where they can build the new house.
他们不知道在哪里可以建新房。
3. Last year, she decided to try out for a volunteer after-school reading program.
她决定去参加一个志愿者课外阅读选拔活动。
decide to do sth. 决定去做某事；to不定式做宾语。
e.g. He decided to get married.
他决定结婚。
4. She still works there once a week to help kids learn to read.
她仍旧在那里一周工作一次来帮助孩子们阅读。
to help kids learn to read
不定式短语作目的状语；learn to read是help的宾语。
5. I can do what I love to do and help others at the same time.
我可以做我所喜欢的事情，同时还可以帮助他人。
从句what I love 在句子中作do的宾语。
