首先，我們應(yīng)該吃的正確．
*不要吃太多的糖果或喝太多的可樂(lè)，或我們的牙齒會(huì)很容易壞．
*多吃奶酪，多喝牛奶和酸奶來(lái)使牙齒結(jié)實(shí)．
*多吃蔬菜和水果，以幫助清潔牙齒．
第二，我們應(yīng)該把這些數(shù)字記在心里．

解答 （正確選A．錯(cuò)誤選B．）
71．B 細(xì)節(jié)理解題 根據(jù)文章第一段中So we should learn to protect them at a very young age．可知我們應(yīng)該學(xué)會(huì)從小保護(hù)他們．故選：B．
72．A 細(xì)節(jié)理解題 根據(jù)文章中Have more cheese，milk and yogurt to make teeth strong．可知多吃奶酪，多喝牛奶和酸奶來(lái)使牙齒結(jié)實(shí)．故填：A．
73．B 推理判斷題 根據(jù)文章Brush your teeth at least twice a day：in the morning and before bedtime． 可知每天至少刷兩次牙：在早上和睡前．這里說(shuō)的是至少兩次，不是說(shuō)多了不行．故填：B．
74．B 細(xì)節(jié)理解題 根據(jù)文章Brush for at least two to three minutes every time．可知：每次至少兩到三分鐘的時(shí)間．所以每次只刷一分鐘是不正確的，故填：B．
75．A 推理判斷題 根據(jù)文章Get a new toothbrush every three months．可知每三個(gè)月?lián)Q一次牙刷．所以一年應(yīng)該換四次牙刷，故填：A．
