     Every object has weight. But the center of its weight is not always in the middle of the object. If the
top of an object is heavier than its bottom, it will fall over easily. We say that its center of gravity(重力)
is high. But if the bottom is heavier, it won't fall easily. Then we say that its center of gravity is low.
     Look at the first picture. This empty box must fall over, because its center of gravity (C) is not above
the line of its bottom (AB).
     Now look at the second picture. There are some heavy things in the bottom of this box. It will not fall,
because its center of gravity is above its bottom.
1. Box _____________will not fall..

2. The main idea of the passage is _________.
A. why things fall over  
B. a low center of gravity
C. a high center of gravity
D. that everything has weight

The most unusual museum in London is the Science Museum. In most museums, there’s no shouting and no running, and you aren’t allowed to touch the exhibits. But the Science Museum is different… because it’s noisy ! People talk about what they can see and do there, and some of the machines are noisy as well. Visiting the Science Museum is fun and it’s a great way to learn about science because you can work things out and try out ideas.
When I visit the Science Museum, I go to the Launch Pad. This is my favorite room because you can do physics experiments. For example, if you want to fill a bag with falling sand, you have to move a kind of truck on wheels into the correct position. I also go to the Rocket Show. You can learn how we travel into space and back again.
Then I go upstairs to the Human and Nature room. You can compare your speed with animals there. You hear a noise and push a button. If you aren’t fast enough, the lion catches you! I’m faster than all my friends, but the lion still catches me.
You can do a lot of things in this museum, but you have to obey some rules as well. For example, you mustn’t take photos of the exhibits in the museum. But you can buy postcards of them in the museum shops.
Above all, the Science Museum is free. That means you can drop in for a few minutes or you can stay as long as you like – it’s open every day, from 10 am to 6 pm. So if you ever go to London, make sure you visit the Science Museum. It’s my favorite museum in the whole world.

       Ever since I was a child, my mouth has caused me trouble. I'm not a bad person; I have a hard time
learning when to keep my mouth closed.
        My mom has told me again and again, "Robert, your constant bad words are hurting me. If you
continue to be this rude, you will get into big trouble."
       It's been a problem at school several times too when teachers have told me something I didn't want
to hear. I used to feel it was my duty to stand up for myself.
        One day in English class I began working on my homework until I heard a classmate talking behind
me. It was Nathaniel, talking to himself as usual.
        I said ever so nicely, "Nathaniel, would you be quiet?"
        Nathaniel continued talking to himself. I quickly shouted "Nathaniel, shut up!"
        For the next five minutes, we threw hurtful words back and forth at each other.
        "At least I don't have an ugly lazy eye like you!" I shouted.
        I knew this would upset him deep inside. It would hurt his feelings and shut him up.
        What I said filled him with anger. He tried to reach over my seat and grab me as he shouted, "That's
it! That's it!"
        Surprised at his reaction, I sat back in my seat. Never had I seen Nathaniel act like this before.
       Later on, we were taken to the principal's office.
       There, Mr. Black, the principal, told us to discuss the matter. It wasn't until then that I finally found
that when I hurt someone physically, the wounds eventually heal. But when I hurt them with my words,
sometimes the pain (痛苦) never goes away.
       At the end of the discussion, I said sorry to Nathaniel.
       When I headed back to my room, I spent some time praying. I began to think about how often what
I said hurt others. But I believe that as I keep praying and asking God to help me, he'll tell me when to
keep my mouth closed.
