Have you ever planned a trip to Europe? What should you consider before you travel? First of all, it is important to think about money. It can be difficult to (A)estimate how much you will spend. (B)A wallet that is lost or stolen can also cause problems.

    Experienced travelers would learn about the money they will use in a foreign country. Most  European countries now use the euro(欧元). So you should know the different value between the euro and the money you use in your own country. We call it exchange rate(汇率). This rate changes every day. You can find out the exchange rate through a bank or the Internet.

It is not wise to carry a large amount of cash(现金). Many travelers prefer to carry travelers' checks(支票) rather than bring cash. (C)They can be used in many places around the world and they can be exchanged for the local money. (D)It is possible to get them back if they are lost or stolen. Travelers can also use bankcards instead of cash. But they must be careful and make sure not to lose them and to keep their passwords secret.

Dear Know,

      I need some advice on how to make friends! I have just moved to a new city. I am 13. I don't know anybody here and I want to make some friends. What's the best way? Where can I meet people?

                                                                                                                           Yours,

                                                                                                                                Tony

Dear Tony,

     There are lots of things you can do. First, you can ride your bike in your neighbourhood and try to find some kids. When you find some, you can go up and talk to them. You should also let your parents know that you want to make friends because they can help you. Maybe you can ask your parents to take you to the library or some places where there are lots of kids. You could try joining an art class or a sports club. These are all great ways to meet people. You can also try making friends at churches (教堂) if you go to churches on Sundays. Try to be active wherever you are, but just be yourself and don't try so hard. It takes time and patience. I hope you will find a best friend soon!

                                                                                                                 Yours,

                                                                                                                         Know

    Today is November 28th. It's my sister Gina's eighth birthday. In the morning, my parents take us to Zig Zag's Store. There my mother buys a red sweater for Gina. And we go to Xinhua Book Store. There I buy some CDs for Gina. My father also buys a book for Gina, and its name is Harry Potter. It's Gina's favorite book. In the afternoon, my parents have a birthday party for Gina at home. Gina's friends, Bill, Jim and Cindy come to the party. Bill brings a new pencil to Gina. Jim gives Gina a soccer ball because she likes playing soccer. Cindy gives Gina an English-Chinese dictionary. Gina is very happy. Oh, I'm Gina's brother. My name is Robert.

    Global warming is a big problem that we have to stop. One of the best things we do is to plant more trees. Trees can take in CO₂ in the air and stop global warming. {#blank#}1{#/blank#}

    A team of scientists at Boston University has been working with NASA to study Earth's green vegetation (植被). They used a special NASA camera and found that global leaf area had increased by 5 percent since the early 2000s. {#blank#}2{#/blank#} That's about one-quarter of the size of the entire Amazon rainforest.

    The growth mainly came from China's forest protection programs, NASA said. For example, since 1962, China has been planting trees in Saihanba, Hebei Province. It was once a desert. {#blank#}3{#/blank#}

    {#blank#}4{#/blank#} Ant Forest, a feature in Alipay app, gives users points for doing eco-friendly things such as walking and going paperless in the office. Users can then use these points to water and grow their own virtual (虚拟的) trees. When the virtual trees are big enough, Ant Forest will plant real trees somewhere in the world. {#blank#}5{#/blank#}

    Jack was seven years old. {#blank#}1{#/blank#} One day, their mother took them to their aunt's house to play when she wanted to go to the big city to buy some gifts. It was the holiday season.

    The children had a good time at their aunt's. {#blank#}2{#/blank#} Then, at half past four their aunt took Jack into the kitchen (厨房). She gave him a delicious cake and a knife and said to him, " {#blank#}3{#/blank#}and give one of the pieces（块）to your sister, but remember to do it like a gentleman(绅士)."

    "Like a gentleman?" Jack asked. " {#blank#}4{#/blank#}"

    "They always give the bigger piece to the other person." said his aunt at once.

    "Oh," said Jack. He thought about this for a few seconds(秒). Then he took the cake to his sister and said to her, " {#blank#}5{#/blank#}".
