冠词后面有名词好像说He ate an apple 这个an是修饰apple 还是特指吖 He ate a big apple He ate an apple这两句哪个是宾语吖 He ate an apple an apple 可以是宾语吗待英语老师回答 如果He ate a big apple He ate a big apple 可以说宾语只是apple吗 He ate an apple 这里的宾语可以是an 急apple 前面加冠词的话是an apple,但是如果前面有一个形容词如red apple,那么前面的冠词用an 还是 He ate a big apple这里是什么修饰apple吖 重写 ann ate an apple. 初三英语被动语态 He ate an apple.(一般过去式)被动语态还有He eats an apple.He ha red apple 前面的冠词用a 还是an 为什么? She ate an apple .改为被动句. 是a apple tree还是an apple tree? half an apple 还是a half apple
