1。Is your history teacher listened (to) carefully in class? listen to the teacher 是词组,不能省。2。Lei Feng's name (is) remembered by all Chinese people.句子中少了谓语动词,要加上。3。The music is sounded beautifulThe music sounds beautiful.表示感观的动词,用主动形式表示被动。即:听,感觉,摸 ,看上去如:It feels warm. 它摸上去很暖(其实是被摸)。That looks beautiful(那个看起来很美,其实是被看).知识在于点滴积累,更在于不懈努力。祝你学习进步,更上一层楼!——另外,正在冲正确率,请记得采纳,谢谢合作!(*^__^*)
