题目内容

18．-Mum，can I play baskball with Tom？
-When your homework    ，you can．（　　）
A．finishB．finishesC．finishedD．is finished

分析 --妈妈，我可以和汤姆一起打篮球吗？
--当你的作业做完了，你就可以去．

解答 答案：D．
首先根据语境推测句意是"--妈妈，我可以和汤姆一起打篮球吗？--当你的作业做完了，你就可以去．"设空处所在的句子是when引导的时间状语从句，用一般现在时代替一般将来时，主语 your homework 是动作finish  的承受者，所以用被动语态，一般现在时被动语态的构成是：主语+am/is/are+动词的过去分词，故选D．

点评 本题考查时态和语态．每个时态都有标志词，熟记这些标志词是做题的关键．在没有时间状语的情况下可以根据语境来对时态做出判断．判断语态的关键则是观察主语是谓语动词的执行者还是承受者．

6．Try this：For a whole day，forget about the clock．Eat when you're hungry and sleep when you're tired．What do you think will happen？
You may be surprised to find that your day is much like most other days．You'll probably get hungry when you normally eat and tired when you normally sleep．Even though you don't know what time it is，your body does．
Inside our bodies are several clocklike systems（系统）that follow a 24-hour cycle（循环）．Everyone is unique （唯一的），which is why you might like to stay up late while your sister always wants to go to bed early．
Regularly staying up late can make kids do worse on tests．And working at night leads to higher rates（比率）of heart disease．
"There is a growing sense that when we eat and when we sleep are important parts of how healthy we are，"says Steven Shea，Director of the Sleep Disorders Research Program at Brigham and Women's Hospital in Boston．
"During the night，we are ready to sleep，"Shea says．"During the day，we are ready to eat and move around．If you change what you are doing，everything is out of phase．That can have very bad result．"
