  本文教给我们如何种植猫草以及如何用瓶子制造音乐。

1. B细节理解题。由第一栏的buy at plant stores可知，可以在植物商店购买猫草种子。

2. A细节理解题。由第一栏的HERE’S HOW中的内容可知，种植猫草正确的顺序应是:把泥土装进花盆—往泥 土里加水，使其稍微湿润—把猫草种子撒在土上—按压猫草种子使其入土—最后再次给泥土浇水。由此可 知A项为正确答案。

3. A同义猜测题。由下文的one to two weeks可猜测此处指 猫草种子发芽的时间，由此猜测sprout意为“发芽”。

4. C细节理解题。由第二栏的HERE’S HOW中的“Arrange the bottles in order from most to least full. ” 可知，瓶子是按照顺序排列的，由此可知C项与原文内容不符。

5. B主旨大意题。第二栏的最后一段主要告诉我们吹瓶子制造的声音有高有低的原因，故选B项。
