【推荐2】The place of the family computer may turn into a hot argue as your children get older. Whether you have one computer in the house or five, you should think the following things as you make a final decision.

There is a certain number of danger if you allow your children to have a computer with Internet in their rooms with no parental direction. They may share improper information and chat with strangers if they know that no one will be watching.

This does not mean that you cannot allow your children to have a computer in their rooms. Think allowing a computer without Internet access. This is especially useful for teens who use the computer for creative projects, playing video games and listening to music. Keep in mind, however, that it is possible that your kids are more skilled at computers than you are and may remove any blocks you have in place.

The way your family computers are used will play a role in deciding where they should be placed. A machine used only for homework will need to be in a quiet place where there is low traffic. One used for chatting online can be in the room where most of the family spend their time. If Mom and Dad use a computer for work, those needs will also have to be thought.

Space must also be considered in computer placement. The computer will need electricity, plenty of desk space and a spot away from this bright light of windows. You will not want it placed in a room where your kids may be noisy.

【推荐3】Healthy eating doesn’t just mean what you eat, but how you eat. Here is some advice about it:

Eat with others. It can help you to see others’ healthy eating habits. If you usually eat with your parents, you will find that the food you eat is more delicious.

Listen to your body. Ask yourself if you are really hungry. Have a glass of water to see if you are thirsty—sometimes you are just thirsty, you need no food. Stop eating before you feel full.

Eat breakfast. Breakfast is the most important meal of the day. After you don’t eat for the past ten hours, your body needs food to get going. You will be smarter after eating breakfast.

Eat healthy snacks like fruits or cheese. We need snacks sometimes. In fact, it’s a good idea to eat healthy snacks between your three meals. This doesn’t mean that you can eat a bag of chips instead of a meal.

Don’t eat dinner late. With our busy life, we always put off eating dinner until the last moment. Try to eat dinner at least 3 hours before you go to bed. This will give your body a chance to digest most of the food before you rest for the next 8-10 hours.

Being trapped (被困) in an elevator (电梯) can be one of the worst experiences of one’s life. Some people who have such experiences may be afraid to use elevator again.     1    

Firstly, take deep breaths and calm down. Too much fear will make you too nervous to think clearly.     2     Secondly, use the emergency (急救) call inside the elevator to let people outside know you are in the elevator.     3     The phone number can be found around it.     4     Even if the workers have known your situation, it may take them a long time to repair the elevator and bring you back to safety. Instead of keeping moving all the time, you are advised to keep calm and relax yourself as much as possible, or you will make yourself tired out.     5    

Children know that summer is probably the most fun of all seasons.    1    , especially, for children aged 14 and under. In the first study of children’s safety in the US, the National Safe Kids Campaign (运动) (NSKC) found that nearly half of the injury-related (与受伤相关的) deaths among children happen in summer.

    2    They always know summer is a dangerous season for children. During the summer, children are out of school and spend more time outdoors.     3     “While we encourage children to be active and spend time outdoors, they need to understand the importance of safety.” said Everett Koop, an expert of the NSKC.

    4    . The NSKC started a “Make it a Safe Kids Summer” Campaign during National Safe Kids Week, from May 5 through May 12. Here are some important summer safety tips from the NSKC:

【推荐3】Alice was very excited. One of her favourite writers had just published a new book. She had saved up her money, and she was ready to buy the book this weekend. She talked about the book with her online chat（聊天）group. A lot of the other kids in the group were going to buy the book, too. In fact, that was the main thing everyone in the chat room was talking about one afternoon.

All of a sudden, Alice got a chat message from Ella, one of the kids in the chat room. The message said that Ella wanted to meet Alice at the bookstore. Then they could buy the new book together. Alice told her mum about the message, and her mum asked, “Do you know Ella from school?”

“No,” Alice answered. “We’ve only chatted online. I don’t think she goes to my school.”

“Listen,” Alice’s mum was anxious and said, “I want you to have friends, but sometimes, people online aren’t who they say they are. And when you’re online, you can’t always tell. So I don’t think it’s a good idea for you to meet this person.”

“But, Mum,” Alice said, “what if it is just a kid named Ella who wants to buy a book with me?”

Alice’s mum considered that for a moment. Then she said, “Let’s do this. Dad and I will go with you to the bookstore to buy the book with Ella. If Ella really is just a kid who wants to meet you in person, that’s great. If not, ________.”

Alice didn’t like that idea. It made her feel like a baby. But she knew her mum was right about safety, so she finally nodded. Then she answered Ella’s message. She told Ella that she and her parents would be at the bookstore the next afternoon.

The next day, Alice went to the bookstore with her mum and dad. When Ella never showed up and then disappeared from the chat room, Alice knew her parents were right. She was glad they were there to be with her.

【推荐2】3D printing is becoming more and more popular. We are now able to print things such as clothing, musical instruments and even cars. People and businesses are able to create the things they need very quickly and easily by using 3D printers.

But can you imagine printing food? Some scientists are trying to change the dining experience completely by doing this. They hope that having a 3D printer in the kitchen will become as common as the blender or microwave. Scientists say that they are easy to use: you simply have to choose a recipe(食谱) and put the uncooked food“inks” into the printer to make the food you want. This means that it would be very quick and easy to create tasty and healthy meals.

Using 3D printers to create your meals would also be saving the environment, There would be less need for traditional growing, shipping and packaging steps as food production would be a lot quicker and better.   For example, tree leaves and insects could be turned into tasty products!

Printing food could also help people who have a swallowing(香咽) trouble. They could program the printer to print softer kinds of their favorite foods so that they would not have difficulty swallowing them.

However, some people think that a future of 3D-printed food would be a disaster. It could take away many jobs, including those for growing, shipping and packaging food. Imagine a world where there was no need for farming or growing crops and the same tastes and structures could be printed from an uncooked “food ink”.   Traditional cafes and restaurants might lose business, too.

Also, there are worries about the healthy value of printed food: is it really possible to get what we need from food-based “inks” or something like that?

As we know, cooking and eating together with family and friends has long been a traditional and enjoyable activity. It is hard to imagine a world where the pastime of cooking is dead and meals can be created at the touch of a button.
