【解析】本文叙述了如果离开家几周的时间，没有人给植物浇水，植物会干枯的，短文给出了一个妙计来解决这个办法。

1.句意：你有一个不愉快的经历吗？因为空前有不定冠词an，所以应该用名词的单数形式。故答案为：experience。

2.句意：幸运地是，我将告诉你一个有用的方式来解决它。这里应该用副词来修饰句子，luck是名词，lucky是形容词，Luckily是副词。故答案为：Luckily。

3.句意：仔细地听！这里应该用副词修饰动词listen，careful是形容词；carefully是副词；故答案为：carefully。

4.句意：首先准备一个瓶子，装满水。短语fill...with...用某物装满。And前后的动词时态应该一致，根据prepare可知，这里是祈使句，所以应该用动词原形，故答案为：fill。

5.句意：然后用手紧紧地把瓶子盖拧上。这里是祈使句，所以以动词原形。cover动词，覆盖。故答案为：cover。

6.句意：确保水不会流出来。短语make sure确保。故答案为：sure 。

7.句意：当瓶嘴周围的土变得潮湿的时候，空气不容易进入瓶子里，瓶子里的水也不会流出来。这里get是系动词，后跟形容词。wet形容词。故答案为：wet。

8.句意：当瓶嘴周围的土变得潮湿的时候，空气不容易进入瓶子里，瓶子里的水也不会流出来。如果句子是肯定句，表示“也”在句末用too。句子是否定句，表示“也”，用either；故答案：either。

9.句意：一些水进入到土壤里，更多的空气代替了瓶子里的水。短语take the place of sth代替某物。故答案为：place。

10.句意：因此，你看见了更多的气泡。as a result因此，表示前后是因果关系。故答案为：result。
