Dear all, <br/><br/>Could you help me clarify the following question about present perfect tense. Thank you very much. <br/><br/>The instruction is that " Complete each sentence using the present perfect tense." <br/><br/>No, she <i>_______</i> (return) home yet. I'm a little worried. <br/><br/>I typed " hasn't returned" in the blank. But the computer screen showed that "wrong". I feel confused about it. <br/><br/>Thanks again.
