All over the world the need for more laptops and computers increases each year. Networks have been part of our life. Probably everyone with a portable device (移動設備} has once logged on to a public WiFi network without paying for it, while they are having a coffee, on a train, in a shopping mall or at a hotel. However, is this kind of public WiFi network safe?
Some networks are better protected than others because encryption (加密）methods are used. Therefore, they are safer than others. But a survey in 2015 showed that more than 950 million records were not protected, including addresses, emails, birth dales, phone numbers, passwords and so on. These open WiFi networks are really not safe, because it is very easy for hackers (黑客） to break into the operating system and get people's private information.
Most smartphones and laptops, by themselves, search and connect to WiFi networks. They usually prefer a network with a connection that has been used before. Hackers' devices are able to record these searches and look like the trusted WiFi networks. When these smartphones and laptops log on to the networks which are not real, hackers can easily steal their private information.
So next time, when we want to use our laptops or our smartphones in public places which offer free WiFi networks，please think it twice or take safe measures before using them.

Mum’s Christmas Surprise
Molly ran back home from school and dropped her schoolbag on the sofa. Then on the table she saw “Mum’s Wish Book” – a mail order catalog（商品目錄） from a gift shop. “Mum,” she said excitedly to herself, “this year you’ll get the gloves you want!” Molly had walked a dog for a neighbor and saved her all year to buy Mum the gloves.
She opened “Mum’s Wish Book” and hoped that she could find these in it. Teas ran down her face when she saw the gloves in the catalog. Mum wouldn’t buy them for herself, because the family had a time on the farm. She once heard Mum say to Dad, “Maybe some day, I’ll have the money to get them.”
Molly ran out by the back door and went straight to the post office. There she carefully filled out the order form torn from the catalog.
“I need to buy a stamp to the form.” She said to Mr. Smith, the only worker in the post office.
“Umm, a pair of gloves?” said Mr. Smith, as he passed a stamp to her.
“Yes, It’s a Christmas gift for Mum, but please don’t tell her. It’s our , OK?” Molly didn’t realize how white Mr. Smith’s beard was until that moment. In face, he reminded her of Santa Claus.
As Molly walked back home, she decided to tell Dad her secret. “You’ve got to check the mailbox every day,” said Molly to Dad. He nodded, with a big smile.
Coming home from school every day, Molly peeked at （偷看） Dad when Mum wasn’t , but every time he shook his head.
On Christmas Eve, Dad came back from mailbox, still empty handed. Molly felt when she went to bed, because she didn’t have the gloves for Mum.
Before Christmas dinner, as Mum took the apple pies out of the oven, Molly began the table. Suddenly, they heard someone pulling up the driveway. From the window they saw Mr. Smith making his way to the door, with a box in his hand. Mr. Smith Mum the box, “I believe this is yours.”
Mum looked from Dad to Molly and opened the box. Her eyes lit up when she saw the gloves. “Oh, who bought these for me?” she asked.
“Santa did,” said Molly smilingly.
“Ho! Ho! Ho! Merry Christmas!” Mr. Smith, with a loud laugh.
It was Christmas that no one would ever forget.
