unaware，形容词，“没意识到；未察觉”的意思，常用的搭配有be unaware of sth.。

（2）like，介词，意思是“例如、比方”，常用于举例。

e.g. I love doing sports like playing basketball and football.我喜欢做运动，如打篮球和足球。

I wonder whether I’ll recognize Phillip after all these years. 过了这些年我不知道是否还能认出飞利浦。

I was wondering if I could borrow your car. 我想知道我是否可以借用一下你的车。

2. Anyhow, my goal is to provide humans with a life of high quality. (P18)句中to provide humans with a life of high quality 为动词不定式短语作表语；动词不定式具有名词、形容词和副词的特征，因此它在句中可用作主语、宾语、表语、宾语补足语、定语和状语。

如：To talk with her is a great honour. 和她说话是一件非常荣幸的事。

His ambition is to become a famous novelist. 他的抱负是成为一位著名的小说家。

3. I would really like to play against a human team, for I have been programmed to act just like them. (P23)sb. would like to do sth. 意为“某人想要/ 喜欢做某事”；此结构还可拓展为：sb. would like to have done sth. 某人本想要做某事（但并未做成），would like sb. to do sth. 想要某人做某事。
