or playing a voice stating the recording subject matching the recording preparation instruction. ### Claim 3 (depends on 1) The video recording method according to claim 1, wherein recording videos for the user and a virtual teacher separately according to a recording sequence matching the recording subject comprises: determining a first time recorded object and a non-first time recorded object based on the recording sequence, wherein the first time recorded object comprises the user or the virtual teacher, and the non-first time recorded object comprises the virtual teacher or the user; recording a video of the first time recorded object; suspending recording the video of the first time recorded object, when the video of the first time recorded object recording reaches a switching node; and recoding a video of the non-first time recorded object, during which the non-first time recorded object responds based on a behavior of the first time recorded object during a video recording process of the first time recorded object, wherein, during the video recording, the first time recorded object or the non-first time recorded object is displayed in a full-screen display mode. ### Claim 4 (depends on 3) The video recording method according to claim 3, wherein when the first time recorded object is the user, recoding a video of the first time recorded object comprises: adding an overlay to the video being recorded for a predetermined length of time to guide the user to enter a recording state. ### Claim 5 (depends on 1) The video recording method according to claim 1, further comprising: displaying text of the response information and/or a picture associated with the response information on a video recording page, when recording a video recorded for the user. ### Claim 6 (depends on 1) The video recording method according to claim 1, wherein determining response information based on a voice content of the user in a video recorded for the user comprises: determining a degree of matching between the voice content of the user in the video and a preset content; and determining that the response information is first-type information to praise the user's behavior through the first-type information, if the degree of matching reaches a threshold; otherwise determining that the response information is second-type information to encourage the user's behavior through the second-type information. ### Claim 7 (depends on 1) The video recording method according to claim 1, further comprising: stitching the video recorded for the user and a video recorded for the virtual teacher based on a recording timing relationship; and playing a stitched video in a full screen mode, wherein, the video recorded for the user comprises a background voice form the virtual teacher, the background voice comprising the virtual teacher's response information to the information expressed by the user during a video recording process. ### Claim 8 An electronic device, comprising: one or more processors; a memory for storing one or more programs, which when executed by the one or more processors cause the one or more processors to implement following steps: prompting a recording subject matching a recording preparation instruction to inform a user of subject information of a to-be-recorded video, when receiving the recording preparation instruction; recording videos for the user and a virtual teacher separately according to a recording sequence matching the recording subject, when receiving a recording start instruction; and determining response information based on a voice content of the user in a video recorded for the user, and playing a voice of the virtual teacher expressing the response information as a video background voice, when recording the video recorded for the user. ### Claim 9 A non-transitory storage medium containing computer executable instructions for executing following steps when executed by a computer processor: prompting a recording subject matching a recording preparation instruction to inform a user of subject information of a to-be-recorded video, when receiving the recording preparation instruction; recording videos for the user and a virtual teacher separately according to a recording sequence matching the recording subject, when receiving a recording start instruction; and determining response information based on a voice content of the user in a video recorded for the user, and playing a voice of the virtual teacher expressing the response information as a video background voice, when recording the video recorded for the user. ### Claim 10 (depends on 1) The video recording method according to claim 1, wherein: the recording subject comprises information contained in the video that needs to be expressed by the user;
