Children and teenagers who spend lots of time in front of screens---especially TVs---are easier to get more weight as they grow, according to a new study.
The findings agree with the research suggesting all that inactive sitting and always watching advertisements may lead to poor eating habits.
Researchers used results from a long-term study of children who took part in the surveys every two years. Children were between ages 9 and 16 when the study started. Out of 4,300 girls in the study, 17 percent were overweight or obese(肥胖的). Twenty-four percent of the 3,500 boys were also above a healthy weight.
The surveys included questions about their height and weight as well as how much time they spent watching TV and DVDs and playing computer and video games.
From one survey to the next, each one-hour increase in children’s daily TV watching was in connection with an increase of about 0.1 points on a body mass index (BMI)(体质指数), which measures weight in connection with height. There’s an increase of about half a pound in weight per extra hour of TV.
“The weight of the evidence is so strong that television watching is connected with unhealthy changes in weight among youth,” says Jennifer Falbe, who led the study while at the Harvard School of Public Health in Boston.
“It's important for parents to know that all the obesity-causing(引起肥胖的)screens really should be limited in their children's lives.” Falbe says. “When children watch TV, there are many food advertisements on TV that might lead them to eat a cookie or drink a soft drink.” What's more, she says, “they can get into a hibernating(冬眠) state on the sofa, even if children are sitting down while playing a computer game.”Which of the following statements can be the best title for the text?
A.A new study on screens. |
B.TVs do harm to children. |
C.The less TV time, the fatter. |
D.Too much screen time leads to obesity. |
How many children took part in the study?
A.4,300 | B.3,500 |
C.7,800 | D.9,800 |
According to the study, one extra hour screen time will cause children about ______ poundfatter.
A.0.1 | B.0.5 |
C.0.3 | D.0.7 |
According to Falbe , what should parents do to stop children getting fat?
A.Limiting the time of children watching TV. |
B.Buying children food advertised on TV. |
C.Not allowing children to watch TV. |
D.Encouraging children to play computer games. |
With the right encouragement and tools, children can develop leadership qualities that are important to help them succeed in all areas of life.Leadership activities and games help build these skills by enabling children to become more self-aware and improve their self-respect.
Good leaders can convey their thoughts and feelings effectively.Poetry, short stories or drawing are ideal activities to introduce children to the concept of leadership. Ask children to think about what makes a great leader and then express their ideas. Games like blind obstacle courses can build communication skills as well.
Planning and organizing is a fundamental leadership quality.Children can learn this skill by helping to plan a concert or play.Instead of assigning just one leader, divide the group into several small ones and assign leaders to each group.One group can be in charge of assigning roles and the second could be in charge of making invitations.How you distribute leadership roles will vary depending on the age of the
children and what you have chosen to perform.
Compromise is a skill of many effective leaders.Goals are obtained faster when arguments don't slow the process.Activities that teach children the art of compromise help them to negotiate with friends and family naturally.Group science projects, for example, can help enable children to learn how to compromise and negotiate.The success or failure of the project will depend on the children's ability to negotiate and
work together.
The ability to work well with others is another important leadership skill.Team sports like baseball can teach children how to work as a group and that their contribution is important to the overall success of the team.This builds their confidence and encourages them to think beyond themselves and their individual needs.What activities can be used to introduce children to the concept of leadership?

Texting pedestrians arena' t just an annoyance to their fellow walkers, but something dangerous to themselves.
“1 was checking emails while walking to work this morning," said Wilbert van den Hoorn.“But it has a serious influence on the safety of people who type or read text while walking."
Anecdotes back him up.A tourist from Taiwan walked off a port near Melbourne last month while checking Face book-bringing an abrupt, and icy end to a penguin- watching visit. Another shopper in the U.S. was too addicted to his mobile phone to notice the fountain ahead! walking straight into it.
And as mobile-phone use has grown-to about 77% of the world's population, the study says-so has the number of phone-related accidents.The number of U.S.emergency-room visits linked to phone use on the move doubled to as many as l,500 between 2005 and 2010, an Ohio State University study recently showed.
Authorities world-wide have taken note.Signs on Hong Kong's subway system advise passengers in three languages to keep their eyes off their phones.Police and transport authorities have also warned the danger in Singapore, where the Straits Times newspaper ranked it as No.2 Bad Habit"' due to the rising number of road deaths.Some U.S.states, including New York and Arkansas, are even considering bans on this act.
The Australian study used 26 volunteers, a third of whom admitted having hit objects while texting.They were fitted with different equipment in different parts of their body, and asked to walk 8.5 meters three times-once without a phone, once while reading a text and once while writing a text-while eight cameras captured the action.
Volunteers using the phone walked slower and with shorter steps (and slowest of all when typing), and! more seriously, they locked their arms and elbows in-like “robots", in the researchers' words.That forced their heads to move more, throwing them off balance.
“In a pedestrian environment, inability to maintain a straight path would be likely to increase potential for hits, falls and traffic accidents," said Mr.van den Hoorn.“The best thing to do is to step aside and stop, or keep off the phone."Which of the following about” Texting pedestrians" is WRONG?

Imagine a house that keeps itself warm in the wintertime. Think of the savings in terms of fuel bills and unfriendly emissions. Such houses in fact exist, called “passive houses”. The concept of these highly energy-efficient buildings took root in the 1990s, before slowly consolidating as a niche construction (生态位构建) concept in the 2000s. Are passive houses now actively moving into the mainstream as sustainable buildings?
For Brian McGarry, an economics lecturer who built a family house based on passive housing criteria in the Pyrenees this year, the arguments look convincing. As his first full winter in the low energy house draws in, we asked him to keep us informed. Do passive houses work?
I had never heard of a passive house in February 2012, when I purchased a plot of land. Nor did I expect that I would be persuaded to build a pre-constructed, custom-designed house based on energy-efficient passive house criteria. It promised to be easier and quicker to build, cheaper to run, and more comfortable to live in. The objective was to incorporate the fundamental concepts of passive energy management into my project: an airtight and highly insulated building envelope; large southfacing double or triple-glazed windows (if possible, filled with argon gas) that passively capture the energy of the sun; a heat recovery ventilation system to provide fresh air; and a simple, low-cost heating system consisting of a modern wood-burning stove, a bathroom heater and a portable radiator backup for when the sun doesn’t shine and temperatures decline. No significant
limitations were placed on the design, and it had excellent environmental credentials. Moreover, the cost was no more than a conventional build.
After six months in use, the house is proving to be both cheap to run and remarkably comfortable–staying cool in the hot summer was effortless, as long as the windows were shuttered or shaded from the sun. Nowstaying warm in the cold, high-altitude December climate also seems easy, so far.
Winter arrived in force in the Pyrenees in November, with abundant snowfalls and temperatures as low as minus 8° Celsius. Though early days, the house has responded well: the stove is lit during cold evenings but the portable radiator has not yet been needed. This type of construction seems not only to make economic andenvironmental sense, but to enhance our quality of life, too.We can learn from Paragraph one that passive houses __________.
A.consume extra energy to keep warm in winter and cool in summer |
B.had been introduced for a decade before the birth of the theory |
C.appeal to both the self-builders and those constructors |
D.refer to a certain house comfortable, costly and also pleasing |
Regarding the passive energy management, the houses have characteristics EXCEPT _______
A.using south-facing windows to take in solar energy |
B.Providing energy for taking a shower when it’s rainy |
C.supplying fresh air with a special heat recovery system |
D.placing more demands and restrictions on the design |
How did Brian McGarry find his self-built passive house?
A.very unaffordable |
B.Energy-consuming |
C.comfortable to live in |
D.Awkward to use |
What is the writer’s attitude towards the passive housing?
A.supportive | B.critical |
C.oppositive | D.doubtful |
