He decide to_____ _____(专攻)English,because he just failed the exam

问题描述:

He decide to_____ _____(专攻)English,because he just failed the exam

不知道 focus on 是不是你要地答案~~

focus on比较好,major in和specialize in是说那种“术业有专攻”的,比如In my university, my major is English, so I major in English.
至于二楼的,decide to do sth刚好是固定搭配,当然可以直接跟动词了,specilize 和 major都是动词,在这里直接跟to没问题

devote himself to

补充楼上的
TO 后面不能直接 specialize
要TO BE specialize in 才行
major 应该不行

major in 或 specialize in
