1. 基本文法说明
这个动词的意思是「变成~；成为~」(=start to be)，因此后面接的字不是名词就是形容词。
例 he became famous when he was only a child. 
他在小时候就出名了。
2. 错误发生情况及修正练习
仔细看看下列的句子，哪里出了错？又该如何修正？
a. peter became to like taiwan eventually.
彼得最终喜欢上台湾了。
b. when i graduated from college, i became to think seriously about my future.
当我从大学毕业的时候，我开始认真的思考我的未来。
c. the parking problem in taiwan becomes more serious. 
台湾的停车问题变得越来越严重了。

3. 错误修正及解释
正确的句子如下：
a. peter came to like taiwan eventually.
become 与 come/grow + to v. 的差别
首先在文法上这一句就不应该用 become，因为 become 后面是接名词或形容词，而非不定词的动词。再者当要表达一个人态度或感觉的逐渐转变时，我们会用 come/grow + to v.。
例 as time passed by, i actually grew to enjoy the food here.
随者时间的过去，我越来越喜欢这边的食物了。
b. when i graduated from college, i began to think seriously about my future.
become 与 begin/start to do sth 的差别
同样的，文法上 became 后面是不接动词的。虽然中文好像有「变得比较会想」这种说法，但是英文必须要用 begin/start to do sth 来清楚表示「开始去~(思考)」。
c. the parking problem in taiwan is becoming more serious.
become 的现在进行式使用时机
当意指还在发生当中还没结束的转变时，记得要用 become 的现在进行式。
