Imagine you are walking through deep snow. As you walk, you leave marks where you've been. That's what happens when we use technology, such as computers, mobile phones and tablets. We leave our digital footprint (数字足迹) and it will never disappear.

Here are reasons why your digital footprint is important to you.

It may influence how others see you.

Even if you think you have nothing to hide, but if people get information about you, they might judge (评判) you by the information you have left online. For example, you tell a bad joke online. Years later, when the university you are applying (申请) to sees it, they might not think it's funny. They may decide you are not the "right" kind of person for them. Future teachers could also search for your online history.

It may leak your personal information.

Not everything can be shared with everyone. For example, you might share your school reports with your parents, but don't want your e-friends to know. If you share them on the Internet, everyone will know. Once posted, it's hard to cut out. So, always share less personal information online to stay safe.

You may lose your money because of it.

There are many people looking at information about you, and some of them want to steal from you. So if you write bank information or card numbers in e-mails or text messages, you may lose your money.

Remember: No one can go online without leaving his digital footprint-but with care, you can control (控制) it. Think before you post, and ask yourself, "Would I want everyone to see this?"

But is this really true? A TV show, The Green Planet, gives us a new look at plants. Shown on Bilibili, it tells the lives of plants, and the wonderful and unbelievable ways that plants work.

Plants contend against each other to live. In the rainforests, different kinds of plants race for sunlight. The forest floor is described as a "battlefield". Only two percent of the sunlight gets through it. Some plants spread (扩展) their big leaves to reach light. But other plants may catch them up and get a lift. Finally, they are both overtaken (超过) by a fast-growing tree. In the same way, some trees may give out something to protect themselves.

Plants also help each other and even communicate. In deserts, if a tree finds water, it will share it with others. Studies also show that plants use fungus (真菌) in the soil as a way to "talk" to each other. It's kind of like how Wi-Fi works. If a tomato plant gets ill, it can tell closer plants about it.

The TV show not only makes us amazed at the plant world, but also pushes us to understand that plants are important. Just as David, the director (导演) of the show says, "All life depends on plants. We depend on them to eat and breathe (呼吸)." It's time to look after wild plants just as carefully as our houseplants.

The tiniest dove discovered some rice under a tree. Excitedly, all the doves came down and began to eat. Suddenly, a large net dropped down on them and in no time, they were all caught inside. Then a man appeared. The doves tried hard to get out of the net, but it was no use. The oldest dove had an idea. He advised all the doves to fly up together, and carry the net at the same time. He said if they worked together, they would be successful. The other doves did so.

The man was really surprised. He tried to follow them, but they were flying high. The doves then flew to a hill because there lived a mouse and they thought he could help them.

When they arrived, the dove king told the mouse what happened and asked him to set them free. The mouse said that he would set the dove king free first. But the king asked him to set his subjects (臣民) free first. And he was the last one to come out.

Finally, all the doves thanked the mouse and flew away together. They felt much closer to each other than before.

Which do you want to choose to help you while you (study), computers or books? Here is an interesting discussion about it. Let's take look.

Some students think that computers are (importance) in our life. They believe computers offer them much (many) choices than books. They can look up information on the computer very (easy). With the computer, all the work can (prepare) very well. And computers and the Internet (change) the world so much so far. No wonder they choose to use computers instead reading books.

However, others strongly think that books are really (help). First, reading books won't hurt their eyes as much the computers. Second, books can help them think harder and deeper. They may ask (they) some questions when they read along. (three), there's another big problem: some students don't use computers to look up information for study. Do you know they do instead? They use computers to play online (game). It is not good for the study. So they would like (read) books. What's your idea?

Mr Martin advised Michael to start by choosing a(n)4. Since Michael dreamed of joining the basketball team, he5 to write about that as the topic. Next, Mr Martin asked Michael to think about his own6 to support his idea. After listing the strongest reasons, Michael felt ready to start writing.

Michael began with his main view—he should be allowed to join the7 team. Then, he explained the reasons and finished his article as soon as possible. And the basketball coach promised (承诺) to let Michael join the team8 he could get a good grade in the competition. Michael felt excited about that. To make sure he spelled everything9, Michael read his article many times. He also checked (检查) the mistakes10 grammar.

His article was the best so that he finally won the writing competition. Everyone in his class took pride in him. Even better, the coach kept his promise and let Michael join the team!

A one-day trip in Hangzhou

Yesterday, I (visit) Hangzhou, a city with many beautiful views and (place) of interest. It was an amazing experience! First, I went to West Lake. The water was (surprising) clear, and there were lots of willow trees around. I took a boat ride the lake and it was full of fun. I also saw the beautiful Broken Bridge. It's famous because of a (China) love story. Even though it's called "The Broken Bridge", it's not really broken. Then, I went to the Lingyin Temple. It's (old) than most temples in China. There were tall trees and impressive rock carvings (石刻) around it. For lunch, I tried some local Hangzhou dishes, including the famous West Lake Fish in Vinegar Gravy. It was delicious and the taste was very special. In the afternoon, I walked round Hefang Street. It was (crowd) with people. I tried some local drinks, and were delicious. As the day ended, I felt grateful for the (experience). Hangzhou is not just a city; it's a poem, a painting and a story. I am really looking forward to (take) a trip there again!

First of all, the international summer camp can bring campers unusual life experience. As we all know, the experience in high school plays a very important role in life. The international summer camp is a great way to get the right values for life. Campers will experience the cultural difference— something they can't get at home from their families. During the international summer camp, students will become more independent and see new things. They can also learn more through talking with students from all over the world.

Making friends is another point. The international summer camp mixes Chinese students with students from other countries in the world. No matter whether they live with a local family or live with other students in dormitories (宿舍), they will all share experiences and cultures with persons from different countries and cultural backgrounds, learn cross-culture communication skills by listening to others and expressing themselves, and improve friendship over several weeks. They often stay in touch with each other by email after the program finishes.

The most exciting thing in the international summer camp is that Chinese campers can get excellent chances to speak and use English in a real English world. Language is not only knowledge; it is a skill which needs to be improved by using it.

Multitasking means dealing with more than one task at the same time or switching (转换) between tasks quickly. While it seems like an efficient (效率高的) way to get more things done in less time, studies suggest our brains might not be as good at multitasking as we think.

Firstly, multitasking can make us less focused and lower the quality (质量) of our work. When multitasking, our attention gets split (分开，分散). This means we might make more mistakes and not do our jobs very well. For example, studying while chatting online can make it harder to understand or remember what you're learning; meanwhile, you probably won't be able to fully enjoy that pleasant conversation either.

Besides, we tend to work less efficiently when multitasking. Studies have shown that it takes our brains more time to switch between tasks, which contradicts the belief that multitasking saves time. Experts call it "task switch costs". We meet "task switch costs" because of the increased mental demand (脑力需求) as our mind jumps from one thing to another.

Lastly, multitasking may hurt people's health, both physically and mentally. For teenagers, their brains are busy forming important neural (神经的) connections. Splitting attention too often might have a serious, long-term, negative influence on how these connections form. Moreover, it could lead to anxiety and a feeling of being constantly behind.

However, does it mean we should never ever try multitasking? The good news is, some forms of multitasking are easier to realize than others, and here are some suggestions on how to choose the right tasks for multitasking:

Try pairing up complex (difficult thus needs full attention and effort) and automatic (done witho7ut thinking) tasks: For example, you can think about a to-do list (complex) while jogging outdoors (automatic), for the latter doesn't need much mental power.

It's also a good idea to rank (分等级) tasks based on levels of importance first. Don't choose very important ones to multitask; instead, try those that don't need so much attention. Save your focused attention for tasks that matter most.

Knowing your limits (极限) is also necessary. People are different, so you should know your own mental and physical limits when multitasking. If you find the quality of your work drops or feel too nervous, you probably should stop multitasking.

Our team was made up of scientists from several fields. We built a few different robotic cushions, and each one offered a different calming experience, like the feeling of breathing, a heartbeat, and one of them even had colourful lights inside. We asked people to try them out and tell us which they liked the best. Most people liked the cushion that felt like it was breathing. So, we decided to work more on that one.

For our final cushion, we made it bigger so it was easier to hug. We made a robotic part that could push air in and out of a balloon inside the cushion, to control the "breathing". We did this because slow breathing helps people feel calmer.

Now, we wanted to see if our cushion really could help with anxiety, so we did a test. The test had to do three things: make people feel anxious, check their anxiety levels, and compare the effect of the cushion to something else.

We made people feel anxious by having them do some difficult math problems in front of others. Afterwards, we asked them to score their anxiety levels from one to ten. To see how well the cushion worked, we put people into three groups. Group A used the breathing cushion, Group B tried meditating (冥想), and Group C just sat quietly without anything to help with their anxiety. After 10 minutes, we asked them to score their anxiety levels again.

We found that people who hugged the breathing cushion had much less anxiety than those who just sat quietly. And we saw that meditation also helped people reduce their anxiety.

Meditation can be difficult because it needs attention and practice, but hugging a cushion is easy! And, you could hug the cushion while doing other things. By doing more research like this, we can find ways to help people who need different ways to feel better. What do you think? Would you like to have a breathing cushion to hug when you're worried?

There were only seven seconds left in the game. Mason's team, the Blazers, was winning 31-29.

Mason was guarding Edwin, the best player on the Engineers team. The crowd shouted: "4...3.…2…"

Edwin stopped, jumped, and shot the ball before the buzzer (终场哨) sounded. The ball went in!

The score was now 31-31.

"We will play overtime," said Mason's teammate Joel. Mason felt bad because he failed to stop Edwin. Edwin smiled at him, making Mason feel even worse.

In overtime, both teams were nervous and made mistakes. Edwin scored twice. Now the Engineers were ahead by 4 points. But then Joel made a great three-point shot with 28 seconds left!

Then Mason had his big moment. With 11 seconds left, he guessed where Edwin would move.

He stole an important pass.

Mason ran fast toward the basket, but two defenders (防守球员) came to stop him. He thought about taking the final shot himself—a chance to be a hero. But then he saw Joel, who was standing alone near the basket.

Mason passed the ball to Joel.

Joel caught the ball,turned,and scored just as the buzzer sounded.

The Blazers won!

Mason and Joel gave each other a high-five."Great pass!" Joel said.

From that day, Mason learned something important:real winning is more than just the score.

Chinese people have already enjoyed math games and toys for thousands of years. Read and choose the right description (描述) for each picture.

I am looking through the articles of the school magazine, thinking about what to1 to match the topics. A story about a boy growing out of loneliness pulls me back to the past.

As a kid, I couldn't help feeling2 in crowds as if they were all eyeing me. Most of the time, I would find a quiet corner, drawing anything that came to my mind, all alone and unnoticed.

As my junior high started, I decided to make a3. I brought myself to talk with others but ended up either acting silly or saying things upsetting them. As a result, I closed the door to connecting with anyone at school and kept to myself. I spent hours and hours in drawing to4 my loneliness.

Life went on like this until one day, my art teacher told me that one of my drawings was chosen for the School Art Exhibition. I was surprised but meanwhile a secret feeling of5 rose from the bottom of my heart. Somehow, I really wished my drawing would be liked, by at least one person. To my surprise, visitors crowded around my drawing6 at its colors, its design, its creativity and... its everything.

The next day, I was greeted by many people with warm smiles. In the classes later on, I started to get engaged. Last week, my math teacher asked a question. I raised my hand and explained confidently. When I heard claps from every corner of the classroom, I7, to others and to myself.

Now, I am an illustrator (插画师) of my school magazine and have won a few prizes. I've made some close friends. And I am no longer a loner but an outgoing and confident girl. And all these changes seem to grow from the8 days.
