高手帮忙翻译一下这篇英语短文，
A good memory is a great help in learning a language. Everybody learns his own language by remembering what he hears when he is a small child, and some children －like boys and girls who live abroad with their parents－seem to learn two languages almost as easily as one. In school it is not easy to learn a second language because the pupils have so little time for it, and they are busy with other subjects, too.
Our mind is rather like a camera, but it takes photos not only of what we see but of what we feel, hear, smell and taste. When we take a real photo with a camera, there is much to do before the photo is finished and ready to show to our friends. In the same way there is much work to be done before we can keep a picture forever （永远）in our mind.
我们的思维就像是照相机，但它所拍下的照片不仅仅是我们看到的，还包括我们感觉，听觉，嗅觉和味觉。我们用真正的相机时，在照片完成之前并向我们的朋友展示之前有许多工作要做。与此类似，我们要在记忆中永久保存一张照片也要做许多准备工作
我们的意识相当於照相机,但它拍照不仅仅是我们所看到的，还有我们所感觉到的，听到的、闻到和尝到的。当我们用照相机拍摄真实照片的时候,在这张照片洗出来的时候有许多事要去做，还要准备拿给给我们的朋友欣赏。同样的方式，在我们永远记住一张图片的时候，我们有许多事情要做。
我们的大脑像一个照相机，但是它不但拍下我们看到的还会拍下我们感觉到的、闻到的和尝到的。当我们用真正的照相机照相之前，需要做很多准备工作才能去拍我们的好朋友。同理，要永远地在我们的大脑中记住一幅图像也需要做很多的工作。
