Those suds you see when you brush your teeth are from detergents like sodium lauryl sulfate .

那些你刷牙时候的泡沫就是来自像钠盐和硫酸盐一类的洗涤剂。

Some names never seem to go out of style , like david or emily . Some never really catch on . Not many girls are named laurel , even fewer are named lauryl sulfate .

一些名字似乎一直没有过时，比如大卫或艾米丽；一些名字则从未变得流行起来，没有太多女孩被起名为劳瑞尔，叫“劳瑞”或“索菲特”的就更少了。
