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.

    However, there are some dangers of WeChat. It is often reported that many traffic accidents are caused by careless drivers who can't help playing on WeChat while driving. And some bad guys even use WeChat to gamble(赌博), which breaks the law. Luckily, WeChat is improved now and then.

    Learning a language can be useful in today's global society. Do you find it difficult to learn a foreign language successfully? Here are some tips to help you out:

    {#blank#}1{#/blank#}

    By far the most important is how much time you are immersed in the language. The more time you spend with the language, the faster you will learn. This means listening, reading, writing, speaking and studying the language. This does not mean sitting in class looking out of the window, nor listening to other students who do not speak well.

    {#blank#}2{#/blank#}

    Build up your vocabulary! You'll need lots. Start to notice words and how they come together as phrases. Learn these words and phrases through your listening and reading. Read online, using online dictionaries, and make your own vocabulary lists for review. Soon you will be able to use them.

    {#blank#}3{#/blank#}

    Listen wherever you are on your MP3 player. Read what you are listening to. Listen to and read things that you like, things that you can mostly understand, or even partly understand. If you keep listening and reading, you will get used to the language. One hour of listening or reading is more effective than many hours of class time.

    {#blank#}4{#/blank#}

    If you do want to learn the language, try to be an active learner. Choose something that you want to listen to and read. Find out the words and phrases that you need to understand in your listening and reading. Do not wait for someone else to show you the language. Discover the language by yourself, like a child growing up. Talk when you feel like it. Write when you feel like it.

    {#blank#}5{#/blank#}

    Do not worry about what you cannot remember, or cannot yet understand, or cannot yet say. It does not matter. You are learning and improving. The language will gradually become clearer in your brain, but this will happen on a schedule that you cannot control. So sit back and enjoy. Just make sure you spend enough time with the language.

    Which meal do we need most, breakfast, lunch or dinner? Dinner is a big meal of the day, but it is not the meal we need most. Breakfast is the meal we need most, because from night to the next morning is a long time to go without food. We may feel hungry or sick if we have no breakfast.

    How many times a day should children eat? Most people eat three meals a day  but five times a day is fine for children. Children are always hungry after school. They should have a snack then. Then they will not eat too fast at dinner because eating too fast is not good. They should also have an apple or an orange between lessons. They are growing. They need to eat often.

    Is it right to eat much when we get tired? It is not good to eat too much. It can make you sick. Wait until(直到)you are rested. Then your food will do you better.

    We can talk about interesting things at the table but we should talk quietly. If we are glad, our food does us better.
