A technology company is developing a lie detector app for smartphones that could be used by parents, teachers - and internet daters. 一家科技公司正在研发一款面向智能手机用户的测谎软件，家长、教师甚至线上约会者都可以使用这款软件。 The app measures blood flow in the face to assess whether or not you are telling the truth. Its developers say that it could be used for daters wanting to see if somebody really is interested in them. 这款软件通过评估人体面部的血流状况来判断受测者说谎与否。研发者表示，线上交友者可以利用它判断约会对象是否真的对自己有兴趣。 Parents could use it on their children to see if they are lying and teachers could work out which of their pupils are truthful. 家长可以用这款软件来分析他们的孩子是否说谎，教师可以凭借它了解到哪些学生具备诚实的品质。 |
