【解析】本文主要谈论保护牙齿的重要性，并从两个方面给出了具体的建议。首先，我们应该吃得对。

不要吃太多糖果或喝太多可乐，否则我们的牙齿很容易变坏。多吃些奶酪、牛奶和酸奶，使牙齿结实。多吃蔬菜和水果，帮助清洁牙齿。第二，我们应该牢记这些数字。每天2次，每天至少两次刷牙：早上和睡前。每次2-3分钟，每次至少刷两到三分钟。3个月，每三个月买一把新牙刷。6个月去看牙医每六个月检查一次。

【1】句意：我们太年轻了，所以我们不必开始保护牙齿。考查理解判断题。根据第一段Teeth are very important for our health. They will be our lifelong friends. So we should learn to protect them at a very young ages.（牙齿对我们的健康是非常重要的。他们将是我们一生的朋友。所以我们在一个很小的年龄时就应该学会保护他们。）结合句意可知此句是错误的，写F。

【2】句意：乳酪，牛奶和酸奶能使我们的牙齿强壮。考查理解判断题。根据在吃的方面的建议（First, we should eat right.）第二条（第五行）Have more cheese, milk and yogurt to make teeth strong.（多吃些奶酪、牛奶和酸奶，使牙齿强壮。）结合句意可知此句是正确的，写T。

【3】句意：午饭后我们不应该刷牙。考查理解判断题。根据第二方面的建议（Second, we should keep these numbers in mind.）第一条2/Day Brush your teeth at least twice a day：in the morning and before bedtime.可知每天至少两次刷牙：早上和睡前，不是午饭后我们不应该刷牙。结合句意可知此句是错误的，写F。

【4】句意：我们每次刷牙只要一分钟。考查理解判断题。根据第二方面的建议（Second, we should keep these numbers in mind.）第二条2-3 Minutes Brush for at least two to three minutes every time.可知每次至少刷两到三分钟，不是每次刷牙只要一分钟。结合句意可知此句是错误的，写F。

【5】句意：一年至少要用四把牙刷。考查理解判断题。根据第二方面的建议（Second, we should keep these numbers in mind.）第三条3 Months Get a new toothbrush every three months.可知每三个月买一把新牙刷，一年12月，需要4把牙刷。结合句意可知此句是正确的，写T。
