Question

She is often heard___English aloud in the morning. A.to read B sang C.to have sung D.to be reading

Answer 1

选A 因为这个句子是说她经常被人听到在早上读英语 要么是
She is often heard reading English aloud in the morning
要么是 She is often heard to read English aloud in the morning
因为主动句中 是 hear sb do /doing sth
即 somebody often hear her read /reading English aloud in the morning
变为被动句时 hear sb do 短语里那个省略了的to要补充出来
即She is often heard to read English aloud in the morning

还有什么不懂得可以hi我

题目问她经常被听到在早上的时候大声朗读英语。
be heard to do sth.是说被别人听到做某事。不能说sing-sang-sung，唱英语。
所以选A.

Answer 3
