According todividedimprove    who   problem 
Tired of puzzling over a problem?Sleep on it!Research by a group of German scientists shows that getting enough sleep makes people better (51)problemsolvers.
They found that people (52)whosleep for at least eight hours each night are better at solving problems and thinking creatively.For their research study,the scientists (53)divided106people into groups.The group that got eight hours of sleep was twice as likely to find a shortcut for solving a math problem than the group that had stayed awake all night.
Skimping on sleep has become a bad habit for many American kids.(54)According to a survey by the National Sleep Foundation,51% of kids ages 10to 18go to bed at 10P.M.or later on school nights.
This is important information for parents and for kids.Getting enough sleep can (55)improve a kid's performance at school.

分析 本文是說(shuō)好的睡眠能讓人們更好的解決問(wèn)題,研究表明每天睡至少八小時(shí)的人更擅長(zhǎng)解決問(wèn)題,對(duì)于孩子而言,足夠的睡眠也能改善他的表現(xiàn).

解答 51.problem.名詞考查.結(jié)合句意make sb+名詞,表示讓某人成為…,結(jié)合前文Tired of puzzling over a problem可知這里填problem問(wèn)題,名詞做定語(yǔ),故答案是problem.
52.who.關(guān)系詞考查.people是先行詞,指的是人,關(guān)系詞用who,作為從句的主語(yǔ),故答案是who.
53.divided.動(dòng)詞考查,結(jié)合106people into groups用動(dòng)詞divide…into…將…分成…,表達(dá)的是過(guò)去的事情用一般過(guò)去時(shí),故答案是divided.
54.According to.短語(yǔ)考查,結(jié)合a survey by the National Sleep Foundation,51% of kids ages 10to 18go to bed at 10P.M.or later on school nights.用短語(yǔ)according to依據(jù)…,故答案是According to.
55.improve.動(dòng)詞考查.結(jié)合a kid's performance at school用動(dòng)詞improve改善,can是情態(tài)動(dòng)詞,后加動(dòng)詞原形,故答案是improve.

點(diǎn)評(píng) 檢查單詞拼寫(xiě)是否正確,是否有時(shí)態(tài)、語(yǔ)態(tài)、慣用法及詞語(yǔ)選用上的錯(cuò)誤,以確保答案的正確性.
