Health & Sickness 健康与疾病 (3)
If someone is diagnosed with a more serious illness such as cancer or AIDS, they’ll need more extensive treatment. When a disease has progressed so far that it will be impossible to cure, then the patient is said to be terminally ill – in other words, the person will definitely die of the disease soon. 如果有人被诊断患有更严重的疾病，如癌症或艾滋病，他们将需要更全面的治疗。当一种疾病已经发展到无法治愈的地步，那么这个病人就被称为病危了——换句话说，这个人肯定很快就会死于这种疾病。
知识点：
1. be diagnosed with...：被诊断患有...
2. terminally ill：病危
3. die of...：死于...

I’m teaching my grandmother how to use a computer. First I showed her how to start up and shut down the computer. Then, I helped her get online or access the internet so that she can check her e-mail. She quickly learned how to write and send messages, reply to an e-mail and forward an e-mail (send a complete e-mail that you received to a new person), but it was a little hard for her to remember how to attach a file to an outgoing message 我在教我奶奶怎么用电脑。首先我给她演示了如何启动和关闭电脑。然后，我帮她上线或上网，这样她就可以检查她的电子邮件。她很快就学会了如何写和发信息，如何回复和转发电子邮件（把收到的一封完整的电子邮件发给新认识的人），但要记住如何在发出的信息中附加文件，对她来说有点困难
