(piano + -ist) · "Her dream is to become a scientist." (science + -ist) 1. 使用一般将来时表达未来规划: · 表计划/意图: "I am going to study medicine to become a doctor." · 表预测/意愿: "I think I will be a good teacher because I love children." · 表临时决定: "(After this talk) I think I will try to learn more about this job." 1. 使用相关句型说明原因: · "I want to be a musician because I enjoy playing the guitar." · "I am going to be an explorer since I am curious about nature." 练习建议: · 找一些动词或名词，尝试加上不同的后缀，看看能构成哪些职业词汇。 · 用“I will...”和“I am going to...”两种句式来造句，体会它们在不同语境下的使用。 · 用英语描述自己或朋友的理想职业、计划及原因，尽量使用本课学到的后缀和将来时结构。 1 学科网（北京）股份有限公司 $$
