【解析】

試題分析：每個人都想很健康，牙齒健康也是非常重要的。我們每天必須刷兩次牙齒，早晨起床和晚上睡覺前。刷牙要至少3分鐘，牙刷三個月要換一次。并且不能只刷前面的牙齒，只有這樣才能讓牙齒保持健康。也可用牙線刷牙，不過很多人不習(xí)慣。

 此題考查動詞，張開嘴露出牙齒，故用動詞show。

 此題考查動詞短語take care of表示關(guān)心照顧

 此題考查固定短語twice a  day表示一天兩次此句的含義是我們要一天刷兩次牙。

 此題考查名詞，根據(jù)語境可知此句的含義是我們應(yīng)該刷所有的牙，不僅僅是前面的

 此題考查名詞，根據(jù)語境可知此句的含義是我們刷牙至少要用3分鐘故填minutes。

 此題考查形容詞，根據(jù)語境可知此句的含義是牙刷必須是柔軟的，故選soft。

 此題考查動詞，牙刷每三個月要換一次，故用動詞change。

 此題考查形容詞，因feel是系動詞其后要用形容詞，根據(jù)語境可知用牙線刷牙感覺很奇怪，故選strange。

 此題考查固定短語keep sth/sb+形容詞表示讓某人或某物處于某種狀態(tài)。因動名詞做主語故用keeps.

 此題考查介詞短語instead of表示代替。
