Question

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（系統(tǒng)）that follow a 24-hour cycle（循環(huán)）．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．"

Answer 1

分析 短文舉了一個例子如果我們沒有時鐘，那么我們的行為和日常生活中的行為是一樣的，如果我們改變我們的行為習(xí)慣，我們的自身系統(tǒng)就會不協(xié)調(diào)，建議人們要正常的活動．

解答 答案：52．B   細(xì)節(jié)理解題．根據(jù)第二段第一句You may be surprised to find that your day is much like most other days．你可能會驚訝地發(fā)現(xiàn)，你的一天和大多數(shù)其他日子一樣．可知如果我們忘記了時鐘，和大多數(shù)其他日子一樣．故選B．
53．A    細(xì)節(jié)理解題．根據(jù)第三段第一行句子Inside our bodies are several clocklike systems（系統(tǒng)）that follow a 24-hour cycle（循環(huán)）．在我們的身體有精確的系統(tǒng)遵循一個24小時的周期．可知這個系統(tǒng)是24小時循環(huán)的．故選A．
54．D    詞義猜測題．根據(jù)上下句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．在晚上，我們準(zhǔn)備睡覺，"Shea說，"在白天，我們準(zhǔn)備吃飯然后走動．如果你改變你正在做的什么，一切都是…，這可能會有非常壞的結(jié)果．可知結(jié)合選項(xiàng)，應(yīng)是說如果你改變你正在做的什么，一切都是不協(xié)調(diào)的，這可能會有非常壞的結(jié)果．所以out of phase意為不協(xié)調(diào)的．故選D．
55．B    主旨?xì)w納題．根據(jù)整篇文章內(nèi)容及其句子最后一段句子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．在晚上，我們準(zhǔn)備睡覺，"Shea說，"在白天，我們準(zhǔn)備吃飯然后走動．如果你改變你正在做的什么，一切都是不協(xié)調(diào)的．可知文章主要告訴我們在日常生活中要遵循精確的系統(tǒng)．故選B．

點(diǎn)評 在通讀全文的基礎(chǔ)上，根據(jù)全文大意，展開邏輯思維，瞻前顧后，認(rèn)真觀察選項(xiàng)，仔細(xì)推敲，確定最佳答案．
