1 . 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.

| C．their homework occupies too much of their time |
| D．modern technological devices consume a lot of their time |
| A．Japan | B．Malta |
| C．Finland | D．Portugal |
| 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 |

2 . As they migrate (迁移), butterflies and moths choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind.
Fascinating as their skills of flight are, migrating behavior has been difficult to study in insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect (测出) such little creatures at such great heights.
To their surprise, though, the insects weren’t passive travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes.
Even in the spring, when most winds flowed northward, the insects didn’t always go with the flow. If breezes weren’t blowing in the exact direction they wanted to go, the insects changed their body positions to compensate (补偿). Many migrating birds do the same thing.
The study also found, butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications. With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help when farmers decide when to spray their crops.

3 . A few months ago as I wandered through my parents’ house, the same house I grew up in, I had a sudden, scary realization. When my parents bought the house, in 1982, they were only two years older than I am now. I tried to imagine myself in two years, ready to settle down and buy the house I’d still be living in almost 30 years later.
It seemed ridiculous. On a practical level, there’s no way I could afford to buy a house anytime soon. More importantly, I wouldn’t want to. I’m not sure where I’ll be living in two years, or what kind of job I’ll have. And I don’t think I’ll be ready to settle down and stay in one place.
So this is probably the generation gap that divides my friends and me from our parents. When our parents were our age, they’d gotten their education, chosen a career, and were starting to settle into responsible adult lives.
My friends and I – “Generation Y” – still aren’t sure what we want to do with our lives. Whatever we end up doing, we want to make sure we’re happy doing it. We’d rather take risks first, try out different jobs, and move from one city to another until we find our favorite place. We’d rather spend our money on travel than put it in a savings account.
This casual attitude toward responsibility has caused some critics to call my generation “arrogant”, “impatient”, and “overprotected”. Some of these complaints have a point. As children we were encouraged to succeed in school, but also to have fun. We grew up in a world full of technological innovation: cellphones, the Internet, instant messaging, and video games.
Our parents looked to rise vertically(垂直的)--starting at the bottom of the ladder and slowly making their way to the top, on the same track, often for the same company. That doesn’t apply to my generation.
Because of that, it may take us longer than our parents to arrive at responsible, stable adulthood. But that’s not necessarily a bad thing. In our desire to find satisfaction, we will work harder, strive for ways to keep life interesting, and gain a broader set of experiences and knowledge than our parents’ generation did.

5 . Language learning begins with listening. Children are greatly different in the amount of listening they do before they start speaking, and later starters are often long listeners .Most children will “obey” spoken instructions some time before they can speak, though the word “obey” is hardly accurate as a description of the eager and delighted cooperation usually shown by the child .Before they can speak, many children will also ask questions by gesture and by making questioning noises.
Any attempt to study the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves as particularly expressive as delight, pain, friendliness, and so on. But since these can’t be said to show the baby’s intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new words to their store. This self-imitation（模仿）leads on to deliberate（有意的）imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech.
It is a problem we need to get out teeth into. The meaning of a word depends on what a particular person means by it in a particular situation and it is clear that what a child means by a word will change as he gains more experience of the world .Thus the use at seven months of “mama” as a greeting for his mother cannot be dismissed as a meaningless sound simply because he also uses it at other times for his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself, I doubt, however whether anything is gained when parents take advantage of this ability in an attempt to teach new sounds.
