    Where can you find a nice place to relax on holiday for both you and your children? Well, I suggest you try the beautiful and green Isle of Wight (IOW). The Isle of Wight is one of the main tourist attractions. Here is some information on a few of the attractions on the IOW.

Dinosaur Isle

    It is located in Sandown, a seaside town on the southeast coast. It's a large, lovely museum, both fun and educational. Here you can see a large fossil collection of all kinds of dinosaurs, as well as a gift shop. You can walk into the past and then the future, learning about the history and the development of the civilization of dinosaurs that lived 120 million years ago.

Robin Hill Country Park

    The park is in the beautiful countryside, and is suitable for children's parties and games. It has five new gardens, and offers great opportunities to see and take pictures of the rare red squirrels.

The West of the Wight

    Here we have the Marine Aquarium, the Archaeology Exhibition and the Model Railway. They offer another opportunity to combine fun with learning. This is a great place to see ancient boats crossing the narrow strait between the island and the mainland.

The Wight Bus Museum

    This museum is run completely by unpaid volunteers. It has a bus collection stored in what was once a warehouse（仓库）. Most of the buses in the museum date back to around the 1910's.

    With all of these choices, what are you waiting for? IOW Tourism welcomes you!

        母亲骂我不会管孩子，她说我：“该管不管！”我也觉得我的儿童教育有点儿特别。
        刚下过雨，孩子们向我请求：
        “让我们光脚去玩，好不好？”
        我满口答应，孩子们高兴极了，脱下鞋子，卷起裤腿儿，三个一阵呼啸而去。母亲怪我放纵，她说满街雨水，不应当让孩子们光脚去蹚水，我回答母亲：“蹚水是顶好玩儿的事，我小的时候不是最爱蹚水吗？”母亲只好骂我一句：“该管不管！”
        我记得童年时候，喜欢做的许多事情都是爸妈所不喜欢的，因为他们不喜欢，我便更喜欢，所以常常背着他们做。我和二妹谈起童年的淘气，至今犹觉开心。比如扯下床单把瘦鸡子似的三妹包在里面，我和二妹两头儿拉着，来回的摇，瘦鸡子笑，我们也笑，连管不了我们的奶奶都笑了起来了（可见她也喜欢淘气了），笑得没了力气，手一松，床单裹着人一齐摔倒地下，瘦鸡子哇的哭了，我们更笑得厉害，虽然知道爸爸回来免不了吃一顿手心板。
        有一次我们要出门，二女儿问她的爸爸：
        “妈妈也出去吗？”
        爸爸说：“是的。”
        二女把两条长辫子往后一甩，拍着小手儿笑嘻嘻地向三女说：
        “妈妈也出去，我们好开心！”
        我正在房里换衣服，听了似有所悟，他们像我一样吗？喜欢背着爸妈做些更淘气的勾当。我的爸妈那样管束我，并没有多大效力，我又何必施诸儿女？这以后，我便把尺度放宽，甚至有时帮助他们把枕头堆起来，造成一座结结实实的堡垒抵御敌人，枕头上常常留有他们的小泥脚印，母亲没办法，便只好又骂我：“该管不管！”我心想，他们的淘气还不及我的童年一半呢！
        成年人总是绷着脸儿管教孩子，好像我们从未有过童年，不知童年乐趣为何物何事。有一天我正伏案记童年，院里一阵骚动，加上母亲唉唉叹声，我知道孩子们又惹了祸，母亲喊：“你来管管。”我疾步趋前，喝！三个丑小鸭一字儿排开，站在那里等候我发落。只见三张小脸儿三个颜色：我的小女儿一向就是“娇女儿泪多”，两行泪珠挂在她那“灵魂的窗户”上，闪闪发光；大女儿的脸上涂着“迷死弗多”口红，红得像台湾番鸭的脸；那老二，小字虽然没写完，鼻下却添了两撇仁丹胡子。一身的泥，一地的水。不管他们惹了什么样的祸，照着做母亲的习惯，总该上前各赏一记耳光，我本想发发脾气，但是看着他们三张等候发落的小花脸儿，想着我的童年，不禁哑然失笑。孩子们善观气色，便也扑哧哧都笑起来，我们娘儿四个笑成一团。

        母亲又骂我：“该管不管！”我也只好自叹“教子无方”了。
