During World Space Week(October 4～10)，you may learn about some of the space's myths. One is: “The Great Wall of China is the only man­made object1from space with the naked eye.”

    You might be2of this claim, but it's not true. In fact, astronauts say that the Great Wall is just one of many man­made3can be seen from space. From an orbit 217 kilometres4the earth，it is5to see highways，airports，bridges, dams and even large6.

    Cities can even be seen clearly from the International Space Station ( ISS, 国际空间站)，7circles about 400 kilometres above the planet. “You can see the8pyramids from space with a pair of binoculars(双筒望远镜). They are a little difficult to9with just your eyes，” said Ed Lu, a US astronaut10the ISS.

    “With binoculars  you  can  also see  roads, harbours and even very large11in the ocean. From the moon, astronauts cannot12any man­made features on earth and the continents are very hard13. On Mars，the earth would appear to the naked eye as14but a bright 'star'. ”15what about the Great Wall? “You can see the Great Wall from space，”Lu said. “But it's a lot16than a lot of other objects. You can only see it in radar images，17in ordinary photographs.”

    No one knows who18the Great Wall story. The earliest reference to it comes in a book by a US writer Richard Halliburton，published in 1938. He wrote，“Astronomers say that the Great Wall is the only man­made thing on our planet visible to the human eye from the moon.”

    Halliburton's books19quite well during the first half of the 20th century. So，if he didn't20the story himself，he certainly spread it widely.

Five steps to better handwriting

    Some kids love handwriting, but others hate when it's time to put their pen to paper. Maybe they are worried about their handwriting. Are you one of them?        Here are five steps that really work!

    Get a great grasp

    Try this — hold your pencil at the top and try to write your name. Pretty hard? But when you hold your pencil the correct way, writing is much easier.        Hold it in place with your thumb, and your index (食指) and middle fingers.

Let the lines be your guide

    Lined paper is your friend! Those lines can help you create letters that are the right size and proportion (均衡).        Also be sure to fill up the lined space completely. Those capital letters should be from the bottom line to the top one.

Slow down

    If your writing is hard to read, try slowing down a little. If you rush, it's hard to control where you stop and start your letters.

    Lower the pressure (压力)

          That makes it harder to make the smooth lines. Try easing up and don't hold the pencil too tightly.

    Lots of games require you to write or draw pictures. So even though it's not schoolwork, you're still using the skills you need to control your pen better.

A. Play games

B. Ask for more advice

C. So “a” should be half the height of a capital “A”.

F. The good news is that just about everyone can improve their handwriting.

G. The best way to hold a pen or pencil is to let it rest next to the base of your thumb.
