1 . Most children now chat daily either online or through their mobile phones.     1     Some are shy in real life but are confident to communicate with others online; others find support from people of their own age on relationship issues, or problems at home.

Sometimes the online world, just like the real world, can cause problems, such as bullying (恃强凌弱) or arguments.     2     But there are also a few people who use the Internet for illegal aims. Children must be made aware of both the good things and the dangers.

    3     Just as you decide which TV programs are suitable, you need to do the same for the websites and the chat rooms your children visit. Remind your children that online friends are still strangers. Reminding them of the risks will keep them alert (警惕的).

    4     So it’s likely that your children may know more than you do. We get left behind when it comes to the latest gadgets and the interactive areas of websites, like chat rooms and message boards.     5     Chatters love to use abbreviations (缩略语) such as: atb (all the best), bbfn (bye bye for now), Idk (I don’t know), xlnt (excellent).

2 . Thirteen-year-old Kaylee has a lot of friends — 532, actually, if you count up her online friends. And she spends a lot of time with them.

But is it possible that Kaylee’s online friendships could be making her lonely? That’s what some experts believe. Connecting online is a great way to stay in touch, they say. However, some experts worry that many kids are so busy connecting online that they might be missing out on true friendships.

Could this be true? During your parents’ childhoods, connecting with friends usually meant spending time with them in the flesh. Kids played Scrabble around a table, not Words With Friends on their phones. When friends missed each other, they picked up the telephone. Friends might even write letters to each other.

Today, most communication takes place online. A typical teen sends 2,000 texts a month and spends more than 44 hours per week in front of a screen. Much of this time is spent on social media platforms (平台).

In fact, in many ways, online communication can make friendships stronger, “There’s definitely a positive influence. Kids can stay in constant contact, which means they can share more of their feelings with each other,” says Katie Davis, co-author of The App Generation.

Other experts, however, warn that too much online communication can get in the way of forming deep friendships. “If we are constantly checking in with our virtual words, we will have little time for our real-world friendships.” says Larry Rosen, a professor at California State University. Rosen also worries that today’s kids might mistake the “friends” on the social media for true friends in life. However, in tough times, you don’t need someone to like your picture or share your blogs. You need someone who will keep your secrets and hold your hand. You would like to talk face to face.

3 . Every festival has its own meaning. Labor Day, for example, celebrates the value of hard work. Thanksgiving is about showing thanks to people around you. And Valentines’ Day is a time when you express love to your loved ones. But somehow it now seems that all festivals we just care about one thing — shopping. And that can be a big problem.

“In a way, over-consumption (过度消费) is the mother of all our environmental problems,” Kalle Lasn once told CNN. Lasn is the organizer of Buy Nothing Day, a day set up in Canada in 1992 to fight against unhealthy spending habits, and has now become an international event. It’s held on the day, which is known as Black Friday — a famous shopping day in the US and Canada.

You can see the irony (讽刺) here.

Even though the idea of Buy Nothing Day was brought up 26 years ago, we seem to need it now more than ever. It’s just as Lasn said, all the different kinds of pollution in our lives today — bad air quality, the reduction of forest area, endangered animal species, and plastic bags found in the ocean — seem to be the same cause: over-consumption.

The latest example is the Singles’ Day shopping craze of Nov 11, which saw a new sales record. But as Nie Li, a campaigner at Greenpeace, told Reuters, “Record-setting over-consumption means record-setting waste.” And it was reported that last year the Singles’ Day packages left more than 160,000 tons of waste, including plastic and cardboard. The Collins Dictionary has also just named “single-use” its Word of the Year, pointing out the problem that there’re too many things we tow out after only using them once.

So, Buy Nothing Day might only be here for one day a year, but it’s not just to remind us to the a break from shopping on that day, but to change our lifestyle completely, focusing on fun “with people we care about” rather than wasting money on useless things.

4 .    

Cheating can happen in a lot of different ways.When people cheat,it’s not fair to other people，like the kids who studied for the test or who the true winners of a game were.

Many people like the action of cheating.In their opinion,it makes difficult things seem easy,like getting all the right answers on the test.But it doesn't solve the problem of not knowing the material and it won't help on the next test—unless the person cheats again.

Some people lose respect for cheaters and think less of them.The cheaters themselves may feel bad because they know they shouldn't get that good grade.And,if they get caught cheating,they will be in trouble at school，and maybe at home,too.

Some kids cheat because they're busy or lazy and they want to get good grades without spending the time studying.Other kids might feel like they can’t pass the test without cheating.Even when there seems to be a “good reason” for cheating,cheating isn’t a good idea.

If you were sick or upset about something the night before the day and couldn’t study,it would be better to talk with the teacher about this.And if you don’t have enough time to study for a test because of swim practice,you need to talk with your parents about how to balance swimming and school.A kid who thinks cheating is the only way to pass a test needs to talk with the teacher and his or her parents so they can find some solutions together.Talking about these problems and working them out will feel better than cheating.

8 . Like most of us, I try to be mindful of food that goes to waste. The arugula (芝麻菜)was to make a nice green salad, rounding out a roast chicken dinner. But I ended up working late. Then friends called with a dinner invitation. I stuck the chicken in the freezer. But as days passed, the arugula went bad. Even worse, I had unthinkingly bought way too much; I could have made six salads with what I threw out.

In a world where nearly 800 million people a year go hungry, “food waste goes against the moral grain,” as Elizabeth Royte writes in this month’s cover story. It’s jaw-dropping how much perfectly good food is thrown away — from “ugly” (but quite eatable) vegetables rejected by grocers to large amounts of uneaten dishes thrown into restaurant garbage cans.

Producing food that no one eats wastes the water, fuel, and other resources used to grow it. That makes food waste an environmental problem. In fact, Royte writes, “if food waste were a country, it would be the third largest producer of greenhouse gases in the world.”

If that’s hard to understand, let’s keep it as simple as the arugula at the back of my refrigerator. Mike Curtin sees my arugula story all the time — but for him, it's more like 12 bones of donated strawberries nearing their last days. Curtin is CEO of DC Central Kitchen in Washington, D.C., which recovers food and turns it into healthy meals. Last year it recovered more than 807,500 pounds of food by taking donations and collecting blemished (有瑕疵的) produce that otherwise would have rotted in fields. And the strawberries? Volunteers will wash, cut, and freeze or dry them for use in meals down the road.

Such methods seem obvious, yet so often we just don’t think. “Everyone can play a part in reducing waste, whether by not purchasing more food than necessary in your weekly shopping or by asking restaurants to not include the side dish you won’t eat,” Curtin says.
