    Every time we go into a museum, we are often told, "Don't touch that!" The Please Touch Museum in Philadelphia is1the opposite. Here we are encouraged to2everything.

    My first visit to the museum was one year ago. I was3to visit the museum as soon as Mum told me its name.4told me that I could climb and jump, and touch everything in the museum.

    This place is more like a5than a museum. It gives kids the chance to learn6play. I loved this place a lot and had to be pulled away by the arm when we were ready to7.

    Each exhibit is a hands-on(亲自实践的) experience. I8enjoyed the very large water table and grocery store(食品杂货店). I had so much fun that 1 didn't even9I was learning.

    The only problem is that this place gets crowded very quickly on weekends,10you need to get 'there early if you don't want to be immersed in(浸没于) the sea of people.

    When you think of a museum, I bet you don't think of a place where children run around. But the Science Museum is different. It's noisy!

    You can get to the Science Museum by going on the London Underground from Waterloo on the Jubilee Line to Westminster. Then take the Circle or the District Line to South Kensington. When you walk out, take a look around you, and you should see it.

    What to bring: at least two bottles of drinks for the kids and f 10 to spend in the cafes. Entrance is free!

    The most interesting and exciting part of coming here is to go to the kids' area, the Launch Pad on the 3rd floor. At busy times, you may have to wait in line, but staff(工作人员) will provide science toys for you and the kids to play with. It is great fun there. And if you love science, it should indulge(满足) you as you will learn about science in a fun way. There are also simulators(模拟装置) on the 3rd floor, so think of Floor 3 as a "fun floor".

    If you want to learn about the museum, then go to the ground floor. They have some things which will interest you.

    Over all, it's a fun experience for the kids and you may enjoy it too. It's also free to get in!

    Boston Children's Museum is the second oldest children's museum in the United States. It has been teaching children with a huge collection of objects(可触摸的实物) since 1913. Here's a list of some interesting exhibits in the museum.

    When a man was walking by some elephants, he suddenly stopped. He wondered why these huge animals were being held only by a small rope tied to their front, legs. No chains, no cages. It was clear that the elephants could break the rope at any time, but for some reason, they did not.

    He saw a trainer nearby and asked why the animals just stood there and didn't try to get away. "Well," the trainer said, "when they were very young and much smaller, we used the same rope to keep them from running away. At that age, it's enough to hold them. As they grow up, they are conditioned to believe they cannot break the rope. They believe it can still hold them, so they never try to break free. "

    The man was surprised. These animals could break free whenever they wanted, but because they believed they couldn't, they were stuck right where they were.

    How many of us go through life like the elephants-- holding onto the belief that we cannot do something simply because we failed at it once before?

    Failure is a part of learning. If we failed once, it doesn't mean we can never succeed. If we try again and again, maybe we will succeed one day. So don't be afraid of failure and keep on trying.
