Teenagers who spend hours in front of the television may have a poorer diet as young adults.

A study，which included nearly 1，400 high school students，found those who watched TV for five hours or more per day had less healthy diets than peers(同龄人）five years later. Why does this happen? Should the parents take any measures?

On the one hand，people who spend a lot of time in front of the TV, especially teenagers，may snack more，and that may affect their long-term diet quality.

On the other hand，TV ads for fast food，sweets and snacks tempt teenagers to eat more of those foods. And TV time might also replace exercise time for some kids.

Lead researcher Dr. Daheia J. Barr-Anderson，of the University of Minnesota in Minneapolis，told Reuters Health a clear correlation between TV time during high school and diet quality in young adulthood. While the heaviest TV viewers were eating the most junk food , those who'd watched less than two hours per day had the highest intake(吸收)of fruits，vegetables, whole grains and high-calcium food. In her opinion，parents should limit and monitor TV viewing.

As far as I am concerned，children should watch no more than two hours of television per day. And parents should set a good example by eating right，being physically active and curbing their own TV time.

1. What's the best title for this passage?

A. People should keep away from TV to keep healthy.

B. Teenagers' TV time may affect their diets later.

C. Why do teenagers like TV"

D. Parents' own habits may affect children later.

Teenagers who do not get enough of the nutrients commonly found in fruits and fish are easier to have bad lungs, coughing and wheezing （喘息）．Teens who eat the least of fruit and especially vitamin C have weaker lungs compared to the others．

Teens who take in less vitamin E, found in vegetable oil and nuts, are more likely to have asthma（哮喘）, Jane Bums at the Harvard School of Public Health found.

Based on these findings．Bums said that current recommended dose（一剂）of vitamin C, 85 mg a day, may not be enough for teens to have healthy lungs．Teens who eat less fruit and don't take in enough fatty acids （脂肪酸） are more likely to have asthma and the signs of breathing difficulty．

Proper amounts of fatty acids are protective, Bums said, though fish, the best source of fatty acids, is particularly unpopular with teenagers．Fatty acids are also found in some nuts as well as some green vegetables'．Smokers who avoid vitamin C will increase their chances of coughing, wheezing and developing phlegm（痰）．

More than 80 percent of teens are getting their recommended doses of vitamin C - mainly from fruit drinks．"I wouldn't approve of drinking them, but at least they're getting their vitamin C from somewhere," Burns said．

Burns added that there are several different ways to get the necessary nutrients．"I think vitamin supplements are fine．I think adding vitamin D to orange juice is fine．But I do think there are added benefits that we don't fully understand of eating whole foods like fruits and vegetables and fish," she said．The researchers did not account for poverty and other factors that often distinguish less-healthy eaters and may explain their findings．

1.According to the passage, what is the problem with teens who don't get enough nutrients?

Nowadays, many of us spend about 10 hours a day in front of a Computer or other electronic devices and less than 30 minutes a day outdoors. The result is that our Brain easily feels tired. We need to give the brain a rest, but how?

David Strayer is a professor of psychology at the University of Utah. He claims that camping may be just what a tech-tired brain needs. His argument finds strong support from Carl and Kate, two experienced campers. Carl, who works for a mobile phone company, says that being outdoors makes him feel relaxed. It also prepares him for the work he must do. "Camping gives us a chance to be in touch with nature and it's very relaxing. When you return to work on Monday, you're in a better state of mind.

On average ,Americans spend about 10 hours a day in front of a computer or other electronic devices and less than 30 minutes a day outdoors. That is a claim made by David Strayer, a professor of psychology at the University of Utah. In his 2017 TED Talk , Strayer explained that all this time spent with technology is making our brains tired.

Using an electronic device to answer emails, listen to the news and look at Facebook puts a lot of pressure on the front of the brain, which, Strayer explains , is important for critical (有判断力的)thinking , problem-solving and decision-making.

So, it is important to give the brain a rest. And being in naure , Strayer claims , helps get a tired brain away from too much technology. More than 15,000 campers from around the world attended an international camping festival in September. That is when friends and family take time off and escape to nature for several days. They take walks, climb, explore , swim, sleep, eat and play. Camping may be just what a tired brain needs.

Take Carl for example .He lives in West Virginia and enjoys camping . He says that staying outdoors makes him feel at ease. It also prepares him for the work he must do. Kate Somers is another example who also lives in West Virginia. She says she enjoys camping with her husband and two children . She calls it a “regenerative” experience.

At the University of Utah , David Strayer has studied both short-term and long-term exposure to nature. He found that spending short amounts of time in nature without technology does calm the brain and helps it to remember better. However ,he found , it is the long-term contact with nature that does the most good. He and his research team found that spending three days in nature without any technology is enough time for the brain to fully relax and reset itself.

1.What is David Strayer’s opinion ?

A.Americans dislike outdoor activities

B.Electronic equipment should be quitted

C.New technologies are a double-edged sword

D.Electronic equipment brings great convenience

高三英语单项填空中等难度题查看答案及解析

In 2010, 700 million people huddled together in front of their television sets to watch the World Cup final between the Netherlands and Spain. Even more are expected to tune in to this year's contest, which kicks off on June 12th with a match between Brazil and Croatia in Sao Paulo. Brazil are the runaway favourites to win the tournament, with bookmakers offering odds of less than three to one on the home team winning the championship．Many experts agree that the country will benefit from a strong home advantage, as local crowds roar on the Seleqao．How much does playing on home turf fealty affect a team's performance?

Sports scientists have come up with all sorts of theories to explain why playing at home helps. In 2007 a study investigated the influence of crowd noise on referees in the English football Premier League. It showed that some were more likely to flash yellow cards and award penalties against touring players than the hosts, because they relied on the split-second rise in the home crowd's roar as a reminder to determine if a tackle deserved punishment. In the most recent season of the Spanish football Riga, two-thirds of all penalty kicks were awarded to the home team.

In the latest English football season, the top 20 clubs enjoyed a home success rate of 50%, while their victory rate on the road was 32%. In 12 of the past 19 World Cups the host nation has made it to the semi-finals and six times it has gone on to win. The effect can be seen in other sports too．　 A　 Before the start of the London Olympics in 2012, UK Sport, a government agency, studied the results of more than 100 big tournaments across 14 Olympic sports. B As it turned out, Britain bettered its 2008 performance by winning 18 more medals（10 of them gold), an improvement of 38% . C At the Beijing games, China won 59% more medals than it had done at the 2004 Athens games. 　 D　 Russia topped the medal table in Sochi：in the previous winter Olympics it had come sixth．

Given these numbers, it is not surprising that teams have poured money into maximizing their home advantage. For example, Brazil has spent a considerable fortune on, if somewhat leisurely, a programme of stadium construction and renovation. In all its home advantage is worth the equivalent of a 0.6-goal headstart in every match, according to Goldman Sachs, an investment bank. Like most others, Goldman predicts that Brazil will triumph this year. Other countries' fans will have to hope for a miracle-and perhaps bid to stage the Cup on their own home turf next time.

1.What does "some" in Paragraph 2 refer to?

A. Crowd noises. 　　 B. Referees.

C. Touring players. D. Host players.

2.Put the following sentence in the most appropriate place marked A, B, C, or D It predicted that the London home advantage would boost Britain's medal haul by as much as 25％．

3.What can be inferred from the passage?

A. Fans may raise their noise levels to cheer their teams up.

B. Brazil will win because of its strong ability.

C. It is a waste of time and effort for countries to hold sports games.

D. The visiting teams have a good chance of winning.
