18．Homework
Do arithmetic problems 15through 25．State the different forms of the verbs on page 50of your French workbook．Read pages 12through 20of the Shakespeare play，and don't forget to fill in the missing chemical symbols on the worksheet．
Sound like a list of your homework for the next few nights-or maybe even just for tonight？（71）A It's your teachers'way of evaluating how much you understand what's going on in class．And it helps strengthen important concepts．
（72）C It's inviting to start with the easy things to get them out of the way．However，you'll have the most energy and focus when you begin，so it's best to use this mental power on the subjects that are most challenging．Later，when you're more tired，you can focus on the simpler things．If you get stuck on a problem，try to figure it out as well as you can-but don't spend too much time on it because this can mess up your homework schedule for the rest of the night．（73）E But don't pick someone whom you'll be up all night chatting with，or you'll never get it done!
Most people's attention spans aren't very long，so take some breaks while doing your homework．Sitting for too long without relaxing will make you less productive than if you stop every so often．Taking a 15-minute break every hour is a good idea for most people．（74）D
Once your homework is done，you can check over it if you have extra time．Be sure to put it safely away in your backpack-there's nothing worse than having a completed assignment that you can't find the next morning or that gets ruined by a careless brother or sister．（75）F Now you're free to hang out．
A．Homework is a major part of going to school．
B．Luckily，you can do a few things to do less homework．
C．When you start your homework，deal with the hardest tasks first．
D．But if you're really concentrating，wait until it's a good time to stop．
E．If you need to，ask an adult for help or call or email a classmate for advice．
F．And no teacher still believes that"chewed by the dog"line-even when it's true!
G．In conclusion，no one is expected to stay long，and people have very different learning styles．
分析 本文主要针对完成家庭作业提出了几个建议，要从最难的题目开始、可适当寻求帮助、每隔一小时可休息片刻，最后要认真检查等．
解答 71．A 72．C 73．E 74．D 75．F
71．A．考查上下文的理解判断能力．后句中的it代指A选项中的homework．句意：家庭作业是上学的主要部分．故A选项符合要求．
72．C．考查上下文的理解判断能力．根据后句so it's best to use this mental power on the subjects that are most challenging可知本段主要是建议学生们先从最难的作业着手，因为一开始你最有精力思想也最集中．故选C项．
73．E．考查上下文的理解判断能力．后句由转折连词but连接，并提到不要找一个整晚聊不完的人讨论作业．故前句应该是说可以求助于某些人．
74．D．考查上下文的理解判断能力．对于大部分人来说每小时休息15分钟是好的，但是如果你能真正地集中精神，那么也可以等到一个合适的时间在休息．故选D．
75．F．考查上下文的理解判断能力．本段主要讲要预防其他一些意外事情给作业带来的破坏．可知F正确．句意：没有老师会相信我的作业被狗嚼了这样的话，甚至是真实的时候．
点评 七选五阅读理解题要在理解文章整体的基础上，补全所缺的部分．针对这个特点，解答时要注意语境和上下文的联系，同时还要注意文章的写作方法和结构．尤其要留心选项中的信息词（空格前后句子中与选项中相同或相近的词），站在作者的写作立场，选出最符合作者原意的句子．
