四、语法填空。
Do you have a dream job? For me, I 15. (real) want to become a doctor. I think it is one of 16. (important) jobs in the world.
Nowadays, many people are busy 17. (work) every day. They don't have much time to relax 18. do exercise. Lots of them are in bad health because they don't have time to take good care 19. themselves. I would like to help them to be healthy again.
I know it's not easy to be 20. excellent doctor. I need 21. (learn) a lot. I am going to study hard to improve my 22. (skill). As a helpful doctor, I 23. (help) sick people. I'll always be there with them when they need 24. (I). I believe my dream will come true one day.

15. really
16. the most important
17. working
18. or
19. of
20. an
21. to learn
22. skills
23. will help / am going to help
24. me

15. 此处修饰实义动词want，需将形容词real变为副词really，用来修饰动词表程度。
16. 固定结构one of + the + 形容词最高级+可数名词复数，表示“最……的事物之一”，因此多音节形容词important的最高级形式为the most important。
17. 固定搭配be busy doing sth. 意为“忙于做某事”，因此动词work要变为动名词形式working。
18. 本句为否定句，并列的两个动作relax和do exercise需要用并列连词or连接，表选择关系。
19. 固定短语take good care of oneself 意为“好好照顾自己”，因此填介词of。
20. 此处泛指“一名优秀的医生”，单词excellent以元音音素开头，因此要用不定冠词an。
21. 固定搭配need to do sth. 意为“需要做某事”，因此填不定式结构to learn。
22. 此处指代多项不同的技能，可数名词skill要使用复数形式skills。
23. 本文主题是谈论未来的职业规划，要用本单元所学的一般将来时，可填will help或者am going to help，符合语境。
24. 动词need后面要接人称代词的宾格作宾语，主格I对应的宾格是me。
