The earliest maps were probably drawn in the Middle East. Some of these maps have1and they show us the people at that time thought the earth flat(平的).As time went by, the pictures became more detailed and maps were more2made. Later on, ancient Greeks(希腊人)used their3of math and science to make maps. Greek maps tell us the Greeks knew the world was 4.

    From simple pictures, mapmaking has turned into a science. Maps are made5 surveying(勘测)land. In the1900s, people around the world started to share information to make6maps. With the help of the photographs taken from the sky and space, maps are now more exactly made than ever.7the world is always changing, we will always need new maps.

    There are many types of maps, but almost all use8and pictures to describe what a place is like when the map is made. A map usually tells what the pictures 9. Some maps may show the whole world. A road map will help you know the10from one place to another. Other maps may use pictures to show the temperature and population in different places.

    How to build good relationships with people from other cultures? Actually, it is important to learn some communication skill. {#blank#}1{#/blank#}.

    Learn about the culture in advance. A little knowledge can go a long way. So if you have time before going abroad or meeting with someone from another culture, try to take time to learn the basic "do's and don'ts" of that culture. {#blank#}2{#/blank#} It's very convenient.

    Be respectful and tolerant. {#blank#}3{#/blank#} Signs of these may appear when you communicate with people from other cultures. However, it is not the time to judge people based on these differences during basic communication. Instead, respect them for what they are, and tolerate them.

    Speak clearly and slowly. But do not shout at others even if they don't understand you. {#blank#}4{#/blank#} Instead, it can be seen as a rude behavior. What's more, even if there are difficulties in communicating with people from other cultures, do not treat other people as though they are stupid.

    {#blank#}5{#/blank#} In some cultures, looking another person in the eye when you speak is seen as a sign of honesty and interest. However, in other cultures, it may be disrespectful.

①Eating good food and getting proper exercise are important to stay healthy. Getting enough sleep is important, too. Experts say that teenagers between the ages of 15 and 20 need 8 to 10 hours of sleep each night. 

②Your body needs to take a rest from all the activities it has done during the day. Your brain needs a rest, too. You are likely to get sick easier without enough sleep. 

③You have a "24-hour clock" inside your body that tells you when to be awake and when to go to sleep.  ▲  Blue light that comes from the Sun tells your brain to keep you awake during the day. When there is no blue light at night, the brain tells the body that it's time for sleep. 

④There are many things that stop the brain from telling your body when it's time to sleep. One of these is blue light at night. Today, people spend a lot of time watching television or looking at screens on computers or smart phones. These devices (装置) give off blue light. If you look at them at night, the blue light can trick your body into thinking it's daytime. Then it is more difficult to go to sleep.

⑤What should you do to get good sleep? Experts say that you shouldn't look at screens that give off blue light for at least one hour before going to sleep. 

⑥ Do not watch TV or use anything with a computer screen in bed. If you need to do something to fall asleep, it is better to read a book. Also, keep your bedroom as dark as you can. This will help you sleep well. 

Do you know the grass in the picture ? It is a kind of grass for cats. It is good for your cat. Are you a cat lover? Do you want your cat to be healthy? Then you can plant this kind of grass at home. Please find the following steps.

What you need: A small planter(花盆) Potting soil (盆栽土) Water

Seeds (种子) (You can buy them at any plant store. )

▲:

Fill the planter with the soil. Water the soil until it is a little wet. Throw seeds across the top layer (层) of the soil, and then press (按)them into the soil. Water the soil again. Keep the soil wet until the seeds begin to sprout (发芽)-about one or two weeks. Then water is needed. When your seeds grow tall enough, you can invite your cat to taste it.

Recharge (充电) Your Body's Battery

My phone is showing that little red low-battery sign. What if I didn't recharge it—no, that would stress me out. But what if I took a few minutes to recharge myself—yes, that would help. But how? {#blank#}1{#/blank#}

Tell yourself the truth. 

When something stressful happens, we often can't help taking a deep breath at first. But we control what happens next. It's possible to work with our stress, rather than against it. Thank it and remind yourself: "{#blank#}2{#/blank#}"

Turn your attention to joy. 

To protect energy stores, turn your attention to being present. Focus on what you can feel grateful for. Smiling can reduce stress. {#blank#}3{#/blank#} Plant something in your day that you look forward to. 

Work your stress out. 

You might think all your feelings live in your brain. But in fact, we feel them with our whole bodies. Doing exercise can help your body reduce stress. It can change how you feel. Also, heating up and cooling down, like taking a shower, may cheer you up. 

{#blank#}4{#/blank#}

Being in crowded and busy places sends our bodies signs of danger. We can recharge our batteries with green space time—look for a park, gardens or plants to calm our bodies and minds. 

Life is short. It's even shorter living on half a battery. We can break our daily stress habits and create more energy.
