Getting familiar with tech
Fr her 85th birthday, I gave my mther an iPad. She'd never used a cmputer. She had a trying relatinship with her TV remte cntrl(遥控)and a miserable track recrd（以往的记录）with her cell.
She was keen(热切的） n a tablet because she knew peple wh had them, and she believed that if she didn't keep up with technlgy,she'd ne day find herself in a cmputerized(计算机化的）kitchen,“unable t pen a can f sup".
Our first task was email. She quickly learned the fundamentals but culdn't see the pint f emailing when she culd phne r visit in persn.
Next, we tackled Netflix. Mm's a mvie lver with an appetite fr murder mysteries(凶杀奇案）.She was astnished by the amunt f crime thrillers that Netflix has n f-fer. One Saturday she called because she was having truble lgging nt
(登录）Netflix.I suggested it might require an update. "They prbably have fewer peple wrking as it's alng weekend," she tld me.
She learned t Zm and Face-Time. She experimented with pd-casts. She started emailing her grandchildren.
Mm is a reader, s we dwnlad-ed the library app and signed her up fr an ecard. Nw she regularly dwnlads e-bks herself. When they are nt immediately available,she puts them n hld and frgets abut them.
She became curius abut all the icns(图标),s we set up a weekly tutrial(辅导课),which takes place ver the phne, each f us with ur iPads. One day, I struggled fr 45minutes t help her find the search bar. "It lks like a magnifying glass(放大镜),”I kept saying.Finally,she asked: "Yu mean the frying pan?"We speak n the phne everyday. We als FaceTime, Zm and email. She pwers thrugh e-bks,marveling that she can check them ut in the middle f the night. She watches TV series and knws what's trending. But she has nt yet successfully surfed the Net. She wuld like t read the newspaper, but pp-up ads(自动弹出式广告）and sidebars are prblematic. She "accidentally"tuches them, and then ends up n sme strange pages.
I can't wait fr the day when we can sit dwn in persn and surf the Net tgether. In the meantime,it's great t see hw much her cnfidence has grwn. Yesterday, she FaceTimed me. "I've made a reslutin," she annunced. "I'm ging t learn hw t perate every piece f technlgy in the apartment – including the TV remte."
