In cities across the US,police dogs have usually been those trained in Europe,at a cost of tens of thousands of dollars for police departments. But now police can get the same work done for next to nothing by simply turning to the countless future K9s in US shelters. “All they need is a chance to prove themselves and these dogs will work as hard as dogs that we bring in from overseas ,” said Croft,the founder of Universal K9.

   Croft has rescued 60 dogs so far from shelters across the South. The organization has trained the dogs in drug and explosive detection,scent tracking (跟蹤氣味) and other work. Once they’re fully trained,the dogs are then delivered to local police departments for free. “Right now,we’re on track to save almost 100 dogs this year,” Croft said.

   Universal K9 currently has 15 dogs in its eight-week class. Sadie,a 5-month-old dog,is the class’ —star student. She was picked up off the street by animal control workers. uI found Sadie on the side of the road one day/' said Centeno;an animal control worker in Texas. /'She was just so playful. She had a lot of energy."

   And the dogs aren‘t just joining police departments; they re also becoming members of police families. Cpl. Wesley Keeling,an officer,said he was unwilling to take on K9 partner Remi,a graduate of Universal K9,at the beginning,but quickly he began to love her. They’ve now been together for 2. 5 months. Keeling said Remi was responsible for searching cars and buildings for (麻醉劑) as well as tracking people who may escape or who may go missing. “Remi is a saved dog ,” Keeling said. “She's proud of herself,I'm proud of her. I can't say enough about her. I really can't.”

    In fact,the sleep cycle shifts later by as much as ： 12 to 18 minutes each year between the ages of 10 and 20!So by the time a 10-year-old who sleeps at 8 pm ' grows to be 17 or 18,his body naturally wants to stay up till 10:30 or 11 pm.

    According to researchers,this is because of a hormone called melatonin(褪黑素) that is produced by the pineal gland — a tiny structure deep inside the brain. Melatonin controls a body's natural d?y-night patterns. It causes a person tò become sleepy by lowering his body's (體核溫度) .It is produced much later in the evening and continues to increase throughout the night.

In fact,AAP advises that middle and high schools should start later 一 not before 8:30 am. But a later Start time means a later end time too. Will that affect after-school activities?

    The U.S. high school rate (輟學(xué)率) has fallen in recent years,with the number of dropouts decreased from 1 million in 2008 to about 750,000 in 2012,according to a study. The number of dropout factories”，high schools in which fewer than 60% of freshmen graduate in four years,decreased greatly during the same period.

   “Clear progress is being made,” said Bob Wise,a former West Virginia governor. “it's not a total success yet. So we shou?dn’ t,take a victory iap. But we can at least st?rt warming up."

    Education Secretary Ame Duncan has said the improving graduation rate serves as evidence that the nation's public schools are making progress. But there* re many reasons that graduation rates can rise. And not all of the reasons have to do with stronger schools preparing more students for life after high school.

    Alabama,for example,made great progress in 2014. Its graduation rate jumped more than six percentage points,the second-biggest increase in the nation. But the increase agreed with a policy change that took in the same year: Alabama students no longer had to pass ? high school exit exam to earn a diploma  (畢業(yè)文憑) .

   It also isn’ t  clear how many students are graduating with the skills they need for the workplace or for college. Graduation requirements vary widely across states,and many states offer different levels of diplomas with different requirements.

    Arizona students can earn a standard diploma that requires four courses in math,four in English and three in science. But they also can earn a “Grand Canyon” diploma,which requires just two courses each in math,science and English — less than many colleges’ requ?ement for admission.

9. The good news about a newly released study is that

A.there’ re few dropouts in u.s. high schools   

B. the U.S. high school dropout rate has fallen 

C. the number of “dropout factories” has increased   

D. the number of high school students is increasing

10. The underlined phrase “take a victory lap” in Paragraph 2 means .

A. lose confidence

B. stop working

C. become too excited  

D. get embarrassed

11. Why does the author mention Alabama?

A. fo prove Alabama's education develops very fast.

B. To show graduation rate doesn't mean everything.

C. To advise students to try to get different diplomas.

D. To warn the U.S. education is not successful.

12. What do we know about the “Grand Canyon”

diploma in Arizona? 一

A. Students need to put more efforts into it.

B. It's much required for colleges in Arizona.

C. Students who get it won’t necessarily be admitted by colleges.

D. It's more difficult to get than a standard diploma.
