Iknow myself better than anyone eles does.我比任何人都了解我自己.have difficulty in是啥意思，能用這個詞造個句子嗎。能把The robot is greeted by students in the classroom.It is also greeted by the sick students in the hospital改為同義句嗎。再給你加五分對…有困難；在某方面有困難I have difficulty in english studing.He usually helps me when I have difficulty in studying.當(dāng)我在學(xué)習(xí)中遇到困難時，他總會幫助我。下面那個是被動和主動的問題students in the classroom greet the robot.the students in the hospital do this too。這是一般現(xiàn)在時，過去式的話在greet后加ed是同義句轉(zhuǎn)換了，不是主動變被動了，不過還是謝謝了
