9．By the time the factory was shut down，ithad dumped（dump） its waste into the lake for years．

分析到这家工厂被关闭的时候，它已经往湖里倒了很多年的垃圾了．

解答本题考查的是过去完成时的用法，by the time+过去时间或一般过去时态，做过去完成时的时间状语，表示过去的过去，故答案应为had dumped．

点评每一种特定的时态都有其相应的时态标志，寻找其时态标志并加以认真分析可以巧解时态试题．所谓时态标志，指的就是某些特定的词、短语或句式，在通常情况下要与某种特定的时态连用，同学们在做题时若能充分利用这些时态标志，同时结合句子语境，就可很快得出正确答案．

Four years ago when I was a boy of 11， I got into the biggest trouble as a kid. It was a Saturday morning. Both my parents were out， leaving me and my 10-month-old sister home alone. Anyway， my sister was still asleep in her room. In fact I had the house to myself. I decided to do some drawing. Soon I gave up. Nothing was on TV， so I felt bored and touched the candles on the shelf …I had an idea! What would happen if I set fire to some kitchen paper? Well， of course it went on fire， but it wasn’t the tiny flame(火苗) I’d expected， and I couldn’t blow it out. I threw it on the floor， and then luckily got my dad’s boots(靴子) and stamped it out.

I thought I was safe until there was a huge hole in my room. When my mum came home later， she smelt the smoke immediately. She dropped the shopping bag， luckily for me， over the hole. I thought this meant she would never see it. However， after running round the house checking for a fire， she of course picked up the bag and saw the hole. Next I was grounded(关禁闭) and in trouble for months. Even worse， the hole was still there， reminding me of what I did.
