一句英语,没读懂
Drinking water containing excessive enamel of teeth to become briitle an chip off,leaving a stained or mottled effect.
这是2005年八月的托福题,我没明白为什么水里面会含有牙齿上的珐琅质?
你摘的这一句不完整,原句应该是:
Drinking water____excessive amounts of fluorides causes the enamel of teeth to become brittle and to chip off,leaving a stained or mottled effect.
所以这里填containing,用来修饰water.
