2. —What do you do on Saturday?????—Play computer games.
3. —When do they visit the website?????—On Saturday evening.
4. —How do I print the document?????—Click “print” and “OK”.
5. —How many emails do you get today?????—Two.[注意]
此句中的特殊疑问词who同时又是句子的主语, 且常被看作第三人称单数, 所以它的后面直接加行为动词的第三人称单数即可。—Who writes the email to you?—Li Ming.Complete the conversations.--- Where do your grandparents live？
