Answer

4.He spent a lot of time practicing playing the piano every day.

【解析】

1.I have to finish the extra homework tonight.意思是“我今晚必须完成额外的家庭作业。”这里是变成否定句，一般现在在时态，主要是I，变成否定记住助动词do+not+动词原形。故答案为(1). don't (2). have。

2.There is plenty of water in the water tank.意思是“水箱里有很多水。”划线部分是plenty of可，water是不可数名词，这里用how much来提问。根据题意，故答案为(1). How (2). much。

3.Kitty hopes she will be a singer in 20 years' time.意思是“Kitty希望她在20年后成为一名歌手。”hope+that从句，可以转化成hope to do的形式。根据题意，故答案为(1). to (2). be 。

4.spend+时间+doing sth.花费时间做某事；practice doing sth.练习做某事；play the piano弹钢琴；a lot of time 许多时间；He spent a lot of time practicing playing the piano every day.意思是“他每天花很多时间练习弹钢琴。”故答案为He spent a lot of time practicing playing the piano every day.
