我和爸爸都有很好的视力，可是妈妈正相反。我们俩想帮助妈妈调整好视力，这样她不带眼镜也能看清东西了。可是有趣的是，我和爸爸也有一些东西是视而不见的，比如零乱的房间，蒙尘的家具和肮脏的地板。但妈妈就能清楚地发现并及时打扫干净。

　　father and i both have good eyesight, but mother doesn't. we want to help mother adjust her eyesight and make her see things clearly without glasses. but it is interesting enough that there are things father and i can't see, such as untidy rooms, dusty furniture and dirty floors. but mother can see them clearly, and will' clean them up as soon as possible.
