While the internet is a great place for learning, socialising and having fun, it can also come with some danger. It’s understandable that you may want to stop your children from ever going online in order to protect them. 1.. Here are five tips to help you talk to your kids about online safety.
1. Be honest about the dangers
As soon as your kids are old enough to get online, have an age-appropriate chat with them about what they could meet with. Be honest about the issue of scammers(骗子)and advise them to come to you if they come across such incidents. Let them know that the anonymity(匿名)of the internet allows people to pretend to be someone they’re not so.2..
2. Encourage them to speak up
Flag certain behaviours or incidents that they should immediately alert you to. These include someone they don’t know trying to communicate with them online, coming across inappropriate sites, and someone threatening them online.
3.Let them know that they won’t be punished
Your kids may be scared to tell you if they’ve encountered trouble online for fear that you may stop the usage of their phone or computer .3.. Your role is to help them and keep them safe.
4.4..
Make it absolutely clear that there are a few things that are completely out of bounds(界限). These include meeting up with anyone they got to know online whom they don’t know in real life, giving away any personal information such as their address or phone number, or your credit card details, and posting personal photos or videos that they wouldn’t be comfortable sharing with the world.
5. Spend time with your kids online
Sit with them when they’re using the computer or phone.5..If you encounter a site or post that is inappropriate, explain clearly why you think so.
A.Find out what sites they’re using or games they’re playing.
B.Set rules for what they shouldn’t do.
C.However, it’s far better to equip them with the right skills so they will be able to deal with dangerous situations.
D.Make it clear that you won’t punish them for being honest.
E.Completely stopping them using Internet is the best way.
F.Just as they wouldn’t trust strangers in real life, they need to be extra careful online.
G.Internet is a place filled with danger
Traveling with kids is 90 percent reminding yourself to live in the moment and 10 percent making up your mind to never again leave your house.
I have an uncanny ability to forget this as soon as we return home from a trip and I've finished washing piles of dirty clothes in our luggage and cleaning all the messy caused by the kids. Extremely tired and annoyed, I would actually begin to miss the place we just left!
Family travel is like childbirth, I suppose. Painful, loud, messy, sort of awful, actually, but also wonderful. And you remember only the wonderful—until you’re back on a plane and your kids are fighting over who gets the aisle seat. Then you remember the bad stuff.
Last weekend, my kids and I flew to Texas for a trip we would have nothing to complain(抱怨) about—big hotel, wonderful view.
And yet—we found things to complain about. The pool was bigger in that other hotel! Why do you get to shower first? They call this coffee?! Luckily, I’ve learned to put my metaphorical coat of armor (盔甲) on as soon as we land somewhere, and it forces complaints to bounce off me and land in a pile at my feet.
For three days, genuine fun was had and annoying complaints were heard and ignored. Until it was time to catch a plane and fly home.
Unfortunately, our flight was canceled. We spent hours finding a hotel room. We hit the hotel pool before bed and swam well into the night, my kids making up songs and laughing so hard at their silly lyrics (歌词) and their crazy good fortune to be swimming at 10: 30 on a school night.
And that was when it hit me that family travel is all those things I said before but it’s also a lot more. It’s taking your kids to parts of the world that will open their eyes and finding that actually, yours need opening too. It’s remembering that joy and memories are where you make them, not where you find them.

Telling a yellow taxi and a binoculars (双筒望远镜)apart is so easy that most people could do it without a second thought. However, it is not so for an artificial intelligence: if you turn the taxi upside down, it sees Binoculars.
This is just one of dozens of examples that show AI is a lot worse at identifying(识别) objects by sight than many people realize. The examples, collected by Anh Nguyen at Auburn University in Alabama, raise concerns about the real-world ability of AI image recognition systems.
Nguyen and his colleagues took images of common objects from the Internet and rotated (旋转) and changed the position of the objects in the pictures. They found this was enough to confuse several AI systems, including Google’s. In one case, a school bus that was correctly identified in the original image was misidentified as a lunch box when upside down in the road. It shows these systems aren’t as intelligent as many people think they are.
Nguyen worries what could happen in real-world situations. For example, it makes sense for a driverless car with AI system to avoid an object it can’t recognize. But if the car stop unexpectedly because it thinks a Coke can is a fire fighting truck, this could be as dangerous as thinking a fire fighting truck is a Coke can. This is one reason why driverless cars will need several sensors (传感器) to provide more information, says Nguyen.
His team has been discovering these problems for the past few years, but nobody knows how to fix them. The biggest problem to progress is that when an AI looks at an image, it can’t extract (提炼) rules that would help it identify a similar one next time – such as the rule that horses have four legs. “To reach a human level of reasoning, we need a way to extract rules from images,” says Nguyen.

A.raise people’s concerns about the safety of AI system.
B.prove that human beings are much smarter than AI systems.
C.introduce the topic concerning AI’s image recognition ability.
D.show a taxi can have different forms when seen from different views.
2.We can learn from the last paragraph that .
A.AI can’t tell a horse and a car apart because they both have four legs.
B.AI can’t reason like human, which is the biggest challenge.
C.AI doesn’t have the ability to tell things apart that look similar.
D.AI can’t identify images from earlier experiences.
3.What is the best title for this passage?
A.Problems remain to be solved.
B.AI is no cleverer than human beings.
C.AI can’t see things from another view.
D.Driverless cars need to be improved.
If you land in India anytime in late February or March, it’s wise to check the dates of the annual Holi festival and bring a spare set of clothes. That’s because for a few days in spring, people crowd the streets and pelt (投掷) anyone walking by with brightly-colored powder to celebrate the arrival of spring and the end of evil. It’s hard to avoid the fun and the paint, unless you stay inside or look angry enough to discourage the custom.
“Watch out, madam!” said my taxi driver in Amritsar as we drove through a crowd of young people pelting each other with powder. “The colors never come out of your clothes,” he said. “And you might be having purple hair for many days.”
I did a quick check. I was wearing black, a color rarely seen in India. It is usually connected with the lowest social classes, and can be viewed as unlucky. I was happy for my clothes to be painted in colors.
“I have some powder I bought for my children. You can have some gladly, to join in our customs.” he encouraged. Holding what the driver handed me as my weapon of choice, I walked into the Holi smoke. At first people politely avoided foreigners. But then a girl in a sari(一种印度服饰) ran up smiling and put paint on my face. I returned the favor with a handful of pink.
With its brilliant clothes, exotic flowers, trucks covered with lights and brightly painted pictures of gods, India is truly one of the most colorful places on the planet!
1.Which of the following sentences about the Holi festival is correct?
A.It falls on the same day each year and is celebrated for a few days.
B.It is a playful cultural event to throw colors at friends or strangers.
C.It has many purposes, celebrating the end of spring in particular.
D.It is fun for local people but a little unacceptable for foreigners.
2.I was happy for my black clothes to be painted in colors because .
A.the festival influenced my taste in fashion.
B.the taxi driver suggested wearing something colorful.
C.black was the color not liked by people in India.
D.a girl invited me to join in their customs.
3.We can learn from the passage that .
A.the color black provides people with a sense of mystery and tradition.
B.foreigners can’t be too careful in the street in India during the Holi festival.
C.a sari, worn especially by Indian women, is a must for the Holi celebration.

This morning, when I looked out the window, I excitedly found it was snowing heavy. Attracted by the beautiful sight, so I decided to go out to take some photos. As I walked on the path in front of our building, I saw a boy suddenly slipping on the snow-covered ground. It was at that moment when I realized what I should do. Immediately, I run back home to get a broom(扫帚) and started to sweep the path. I worked so hard that he sweated a lot. An hour later, a thick snow was cleared away. Looked at the clean path, my neighbor all smiled and gave me the thumbs up.
