A couple (夫妇) have travelled around the world in 297 days—without taking any planes Tom Fewins and Lara Lockwood used 78 buses, 61 trains, 34 cars, 18 boats, six bicycles, and even one elephant. They wanted to prove that tourists can still be well travelled without damaging the environment. They aimed to product less than 3,000 kg of carbon dioxide(二氧化碳)， compared with six times that amount if they had gone by plane.

    They spent ten months travelling44，609 miles through l 8 countries on land and sea．The couple's world tour began in June 2008 with a two-hour bus journey to London from their home in Oxfordshire．They took the train，Eurostar，to Brussels and then caught a bus and train to Hamburg before going to Copenhagen．The couple even rode on an elephant for l 5 miles through the Chinese part of the Mekong River(湄公河)．

    The couple hoped to write a book based on their journey to teach other travellers how to travel without damaging the environment．

    Being healthy means a person eats well, gets a lot of exercise, and has a healthy weight. Here are some rules for a kid who wants to be healthy. Try your best to follow the rules.

    Eat All Kinds of Food

    You may have your favorite food, but the best choice is to eat all kinds of food. If you eat different food, you are able to get the things your body needs.

    Drink Water and Milk

    When you're really thirsty, cold water is the best. And there's a reason some schools offer milk. Kids need calcium to build strong body, and milk is a great choice.

    Listen to Your Body

    When you're eating, notice how your body feels and whether（是否）your stomach feels comfortably full. Sometimes people eat too much because they don't notice when they need to stop eating. Eating too much can make you feel uncomfortable.

    Limit（限制）Screen Time

    What's screen time? It's the amount of time you spend watching TV, playing video games and using the computer. The more time spend on these sitting-down activities, the less time for active exercise.

    World Environment Day is on June 5th every year in the world. It makes people realize the problems of our earth. From June 5th to 16th of 1972, the UN had a meeting in the capital(首都) of Sweden(瑞典)—Stockholm. This was the first meeting to study how to protect the environment. We have only one earth, so everyone should do something to protect our earth. We should try to do the 3Rs every day—reduce(减少), reuse and recycle(循环). We should buy things without lots of packaging(包装). Use many things in our neighborhood—They don't have to travel very far and so they can reduce pollution. Recycle all the things you use. Carry reusable bag for shopping.

At home, we should try to save water and electricity every day. When we go out, we'd better walk, ride bikes or take a bus. Try to plant more trees and use less paper to protect the forests on the earth. And we should see every day as World Environment Day and try to do anything to help our environment.

Information Card

    I always knew that I depended way too much on my phone, but I didn't know how much. So I decided to do this challenge(挑战) to find out.

     Every morning since I got a smartphone, I've used The Weather Channel App to find out what to wear. On the first morning I had to dress without guidance, but thankfully I was able to guess that the day would be cold and foggy by looking out of my window.

    I couldn't tell what time it was. I haven't worn a watch for more than a year, because my phone showed the time. So I was late for picking up friends who had been on the bus for two hours from Santa Monica to Palos Verdes. I was also late for my part-time job. And even worse, I couldn't call people to tell them that I was running late.

    Getting to places was harder, too. I got lost because I couldn't use the GPS(导航系统) on my phone. My driving, though, got a lot safer because I no longer had my phone in one hand checking directions while driving with the other.

    But the number one trouble was not having my contact list (联络簿). I forgot to write down my friends' and family members' phone numbers before I started the challenge. It was sad to realize that I couldn't remember my brother's and my mom's cellphone numbers. Oh, how I wished to turn on the phone for just a second to look up phone numbers!

    Even with all the problems, however, I found peace not worrying about missing a text message or an email.

    This challenge was a great learning experience. It surprised me how I'd taken no notice of even the simplest things like remembering phone numbers. We all should take some time to think about how we can depend less on our cellphon
