就是用法的區(qū)別,意思大致相同,表示“確定要做某事”
make sure to do sth 就是sure后面跟動(dòng)詞不定式,有表示將來(lái)時(shí)的意味
如：i make sure to finish this work later.
be sure of sth/ doing sth 就是sure 后面跟名詞或者動(dòng)名詞
如：i 'm sure of having finished this work
be sure that 就是sure 后面跟一個(gè)完整的從句,that 可以省略
如：i am sure that i will finish this work later
be certain of/about的用法跟be sure of 相似,后面跟名詞或動(dòng)名詞
