Sleep deprivation(缺失)is an important hidden factor in lowering the achievement of school pupils, according to researchers carrying out international education tests.
It is a particular problem in richer countries with sleep experts linking it to the use of mobile phones and computers in bedroom late at night. Sleep deprivation is such a serious problem that lessons have to be dragged down to a lower level to suit sleep-deprived learners, the study found. The international comparison, carried out by Boston College, found the United States to have the highest number of sleep-deprived students, with 73% of 9- and 10-year-olds and 80% of 13- and 14-year-olds identified by their teachers as being negatively affected.
In literacy(读写能力) tests there were 76% of 9- and 10-year-olds lacking sleep. This was much higher than the international average of 47% of primary pupils needing more sleep and 57% among the secondary age group.
Other countries with the most sleep-deprived youngsters were New Zealand, Saudi Arabia, Australia, England, Ireland and France. High-performing Finland is also among the most lacking in sleep. Countries with the best records for getting enough sleep include Azerbaijan, Kazakhstan, Portugal, the Czech Republic, Japan and Malta.
The analysis was part of the huge date-gathering process for global education rankings, the Trends in International Mathematics and Science Study(TIMSS)and Progress in International Reading Literacy Study(PIRLS)
“I think we underestimate the impact of sleep. Our data show that across countries internationally, on average, children who have more sleep achieve higher in maths, science and reading. That is exactly what our data show,” says Chad Minnich of the TIMSS and PIRLS International Study Center.
“It’s the same link for children who are lacking basic nutrition,” says Mr Minnich, based at the Lynch School of Education, Boston College. “If you are unable to concentrate, to attend mentally, you are unable to achieve at your best level, because your mind and body are in need of something more basic. Sleep is a fundamental need for all children. If teachers report such large proportions of children suffering from lack of sleep, it’s having a significant impact. But worse than that, teachers are having to adjust their instruction based on those children who are suffering from a lack of sleep. The children who are suffering from a lack of sleep are driving down instruction.”
That means that even the children who are getting enough sleep are still suffering from this sleep-related lowering. What did the researchers of Boston College try to find?
| A．Why children don’t get enough sleep |
| B．How many hours children sleep every night |
| C．The relationship between sleep and test results |
| D．The relationship between sleep and health |
Many children suffer from sleep deprivation because _________.
| A．they sit in front of the TV for too long |
| B．they can hardly sleep soundly and deeply |
| C．their homework occupies too much of their time |
| D．modern technological devices consume a lot of their time |
Which of the following countries has the most sleep-deprived students?
| A．Japan | B．Malta |
| C．Finland | D．Portugal |
Why are children who get enough sleep also victims?
| A．Because they are disturbed by sleep-deprived students |
| B．Because teaching is driven down by sleep-deprived students |
| C．Because they have to spend time helping sleep-deprived students |
| D．Because the teachers waste time disciplining sleep-deprived students |
Let’s say you have a piece of wood, a nail, and a hammer. Pretend the wood is a person, and the nail is a mean rumor(谣言) about that person. If you hammer in the nail, you’re obviously hurting him or her. If you then pull out the nail, there’s still a hole in the wood, and the damage has been done.
There are many reasons why that nail of a rumor can be so harmful. Rumors are, quite simply, a form of bullying(欺侮). When a person or a group makes up a rumor about someone or decides to spread gossip, it’s usually to hurt someone, break up a friendship, or make someone less popular. It’s the same thing as teasing, only it’s done behind someone’s back instead of to his or her face.
When you spread a rumor about someone, you’re sending a signal that the person is outside of the group, and somehow less worthy of friendship than others. You’re making fun of that person or pointing out negative things about him or her. This can let others think that it’s okay to make the person feel bad, and make him or her an outsider.
We need to be able to trust our friends, and gossip and rumors can break this trust. If you tell a personal secret to a friend, and he turns around and tells it to someone else, you might feel like you will get burned if you ever get close to him again.
Letting a rumor influence your behavior is like letting someone else make a big decision for you. Let’s say you hear that the teacher plans to call a Snow Day tomorrow because a blizzard (暴风雪) is coming. Expecting a day off, you don’t do your homework. The next morning, the blizzard turns out to be nothing more than a drizzle(毛毛雨), and school isn’t off after all. You get zeroes on your work. To tell a rumor and a tease apart, you depend on ______.
| A．whether it is done behind someone |
| B．whether it is painful or not |
| C．whether it is a kind of bullying |
| D．whether it is spread fast. |
If a rumor is spread about someone, others may_______.
| A．point out his or her advantages |
| B．keep away from him or her |
| C．not feel he or she is an outsider |
| D．be hurt if getting close to him or her again. |
The purpose of this passage is to _______.
| A．advise on how to deal with rumors |
| B．teach us how to judge a rumor |
| C．find out why rumors spread fast |
| D．explain why rumors hurt |
Last spring, members of Alaska’s Troop 34, based in Fairbanks, trudged (跋涉) out into the snowy wilderness to take part in their state’s Take a Kid Trapping program. In many parts of the state, beavers （海狸）are pests and need to be controlled.
The 10－to－12－year－old girls found out where beavers lived, set traps, and skinned the two animals they caught. The girls hope to catch ten more beavers so that the entire troop can make mittens and hats with the fur. They also want to cook beaver meat.
Troop leaders and members say the Scouts are doing a good deed by helping control the state’s beaver population. But animal－rights activists say trapping is cruel. They want the Girl Scouts to stop in their tracks.
Beavers aren’t only causing a problem in Alaska. Residents in Sampson County, N.C., have turned to a local committee to help them battle the growing beaver population there.
County landowners are frustrated after the county spent more than $ 50,000 in eight years trying to reduce the beaver population through a government program. The joint state and federal program included paying money to trappers for every beaver carcass they trapped.
Many local residents say that the program didn’t work because there were too few trappers. That’s why the county set up its own committee to investigate other ways to control the area’s beaver population.
The county will rely on its own beaver－trapping program. It has hired a trapper to set traps in various areas. The county will pay $10 for every beaver carcass.
Why do many people say that beavers are a nuisance? For beavers to survive, they need lots of water. Water provides the large rodent （啮齿动物）with a place to hide from meat – eating animals. Beavers also store food underwater for the winter. When there’s not enough water in a particular area, beavers get busy building dams.
Beaver dams can cause major flooding and damage to the surrounding countryside as the animals cut down trees to use in their construction projects. Beavers build canals to transport heavy objects.What is Alaska’s Troop 34?
| A．A team of the Boy Scouts. | B．An army. |
| C．A team of the Girl Scouts. | D．A sports team. |
Why does the troop hope to catch ten more beavers?
| A．To fulfill their task. |
| B．To sell them for money. |
| C．To get enough fur. |
| D．To exchange them for mittens and hats. |
Which of the following statements is TRUE?
| A．Sampson County has to find a new way to control the beaver population there. |
| B．The government program in Sampson County has proved to be a success. |
| C．The local government has controlled the number of beavers in the County. |
| D．More and more trappers now start to set traps in Sampson County. |
Local residents hate beavers because they can ___________.
| A．cause damage to dams |
| B．block up canals with heavy objects. |
| C．do great harm to construction projects. |
| D．badly damage the environment and cause floods. |
What is your body language saying to your children? What is their body language telling you? I had the honor of hearing Jan Hargrave speak the other day. She is one of four body language experts in the US. Jan Hargrave says we lie with the right side of our brains, so it is our left hand that gives us away. A person touching his nose, pulling at his ear or rubbing his eye with his left hand might be lying to you. Also, a person who, in any way, crosses any fingers might just be lying. That, she says, is a holdover(遗留物) from childhood, when we crossed our fingers to signal that we didn’t mean what we were saying. When children squint(眨) their eyes, move their body away from you, or can’t seem to make good eye contact, you may need to ask for a little more clarification.
But just as important, children learn early how to read our body language when they are conversing(交谈) with us. Here are some acceptance signals to let them know you are interested when they are talking to you. Lean(倾斜) towards them. Make good eye contact and smile. Open your arms. Let your hands relax with the palms(手掌) showing: an open, upward palm always show acceptance. If your legs are crossed, make sure you are not crossing them away from your child. These are important because they signal to your child that you are focused on them and are accepting and welcoming them into your world.
By paying attention, we can open those lines of important communication with our children and we can see the truth more clearly. I think it would be a mistake to use these tools to lie, but we need to be aware of the signals we are giving so we can show people that they really do matter to us. According to Jan Hargrave, we can tell whether a person is lying by _______.
| A．observing his/her left hand’s movements. |
| B．looking at how he/ she crosses his/ her fingers |
| C．observing whether he/ she uses body language |
| D．making good eye contact with him/ her |
We can learn from the passage that body language _______.
| A．is hard to master for children |
| B．can be understood in different ways |
| C．may help improve communication |
| D．is more likely to hide the truth |
Which of the following does NOT show acceptance to people?
| A．Smile while making eye contact. |
| B．Open your arms to them. |
| C．Relax your hands with the palms showing. |
| D．Cross your leg away from them. |
In the last paragraph, the author seems to suggest that parents_______.
| A．spend more time with their children |
| B．learn to read and use body language |
| C．pay attention to family communication |
| D．try to prevent their children from lying |
Two travelling angels stopped to spend the night in the home of a wealthy family. The family was impolite and refused to let the angels stay in the guest room. Instead the angels were given a space in the cold underground room. As they made their bed on the hard floor, the older angel saw a hole in the wall and repaired it. When the younger angel asked why, the older angel replied, "Things aren't always what they seem."
The next night the pair came to rest at the house of a very poor, but very kind farmer and his wife. After sharing what little food they had, the couple let the angels sleep in their bed where they could have a good night's rest. When the sun came up the next morning, the angels found the farmer and his wife in tears. Their only cow, whose milk had been their only income, lay dead in the field.
The younger angel was very angry and asked the older angel, "How could this happen? Why did you not watch out for the cow? The first man had everything, yet you watched over his house," she accused. "The second family had little but was willing to share everything, and you did not help."
"Things aren't always what they seem," the older angel replied. "When we stayed in the underground room , I noticed there was gold stored in that hole in the wall. Since the owner was so greedy and unwilling to share his good fortune, I asked God if I could seal the wall so he couldn't find it. Then last night as we slept in the farmer's bed, the angel of death came for his wife. I asked God if the angel could take the cow instead. You see, things aren't always what they seem. "Why did the older angel repair the hole for the rich family?
| A．Because she didn't like the greedy owner. |
| B．Because she wanted to save the gold for the poor. |
| C．Because the underground room was too cold to stay in. |
| D．Because she believed that one should always be ready to offer help. |
The younger angel was very angry because ________.
| A．the older angel killed the farmer's cow |
| B．the older angel treated the two families differently |
| C．the wealthy man gave them a bad place to live in |
| D．the angel of death took the cow away |
Why did the older angel let the farmer's cow die?
| A．Because God wanted the older angel to take the cow. |
| B．Because she wanted to teach the younger angel a lesson. |
| C．Because she wanted to save the farmer's wife. |
| D．Because she was sympathetic to the rich. |
The story tries to tell readers that ________.
| A．angels are always ready to help the poor |
| B．sometimes things are not what they seem |
| C．angels are always ready to help the rich |
| D．the young should always learn from the old |
Most Americans believe that someone isn’t grown-up until the age of 26 and they should complete their education, have a full-time job, have a family to support and be financially independent. They also believe that becoming a real grown-up is a process which begins at about the age of 20 and takes about five years, according to the report from the University of Chicago’s National Opinion Research Center.
The findings are based on a representative sample of 1,398 people over the age of 18 who were surveyed in person. The survey found that people expect the transitions to grown-up status to be completed at the following ages: age 20.9 self-supporting; age 21.1 no longer living with parents; age 21.2 having a full-time job; age 22.3 education completed; age 24.5 being able to support a family financially; age 25.7 getting married; and age 26.2 having a child.
“There is a large degree of agreement across social groups on the relative importance of the seven transitions,” said Tom Smith, director of the survey. The only obvious pattern of differences is on views about supporting a family, having children and getting married. Older adults consider these more important than younger adults do. This probably shows in large part a change in values across generations away from traditional family values. The most valued step toward reaching adulthood, the survey found, is completing education, followed by full-time employment, supporting a family, financial independence, living independently, and marriage.According to the first paragraph, someone is a grown-up when he _______.
| A．has found a full-time job |
| B．has finished his study in university |

| B．being grown-up is a process which takes some time |
| C．all people think completing education means being grown-up |
| D．the survey found everyone had a different view about being grown-up |
