Too much TV-watching can harm children’s ability to learn and even reduce their chances of getting a college degree, new studies suggest in the latest effort to examine the effects of television on children.
One of the studies looked at nearly 400 northern California third-graders. Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedroom TVs.
A second study ,looking at nearly 1000 grown-ups in New Zealand, found lower education levels among 26-year –olds who had watched lots of TV during childhood .But the results don’t prove that TV is the cause and don't ride out that already poorly motivated youngsters(年轻人）may watch lots of TV.
Their study measured the TV habits of 26-year-olds between ages 5 and 15. These with college degrees had watched an average of less than two hours of TV per weeknight during childhood, compared with an average of more than 2 1/2 hours for those who had no education beyond high school
In the California study, children with TVs in their rooms but no computer at home scored the lowest while those with no bedroom TV but who had home computers scored the highest
While this study does not prove that bedroom TV sets caused the lower scores, it adds to accumulating findings that children shouldn't have TVs in their bedroomsAccording to the California study, the low-scoring group might .
| A．have watched a lot of TV | B．not be interested in math |
| C．be unable to go to college | D．have had computers in their bedrooms |
What can we learn from the last two paragraphs?
| A．More time should be spent on computers. |
| B．Children should be forbidden from watching TV. |
| C．TV sets shouldn't be allowed in children's bedrooms. |
| D．Further studies on high-achieving students should be done. |
What would be the best title for the text?
| A．Computers or Television. |
| B．Effects of Television on Children. |
| C．Studies on TV and College Education. |
| D．Television and Children's Learning Habits |
Keeping pace with teachers is a fine way to study English.Teachers are experienced and their plans are systematic.But remember to work in a way that suits you.It's important to learn from past mistakes as well.Keep a notebook to make a record of the mistakes you make－it'll help you avoid making the same ones later.
The time of life may be hard，but you're not alone.You may be busy studying，but you can show your care by calling your friends or sending short messages.Don't let your friendships die.
It's as important to live well as it is to study well.Going to bed no later than 11：30 pm is vital.It puts you in the right mood for the next day.You needn't follow a special diet，but make sure you are eating nutritious meals each day.
The person who plays well，studies well.Having a lot of schoolwork doesn't mean having to give up other activities.Playing basketball or having a talk with your classmates can relax yourself.Time_out is not a waste of time but helps you study more efficiently.
Besides taking the big exam，you have other choices for college.I took the independent enrollment exam held by Peking University and some other students even were preparing to study abroad.Pay attention to any relevant information you can find，whether it's from school，the news media or other sources.What should you do if you want to keep your friendship fresh?
| A．Have frequent talks with them. |
| B．Always have lunch with them. |

Hu Li's heart sank due to the color of the air.Driving 140 kilometers from Tianjin City to Beijing last week，she held her breath as the air became a charcoal grey haze(炭灰色的阴霾)．The 39yearold businesswoman has lived in Beijing for a decade，and this past month，she said，brought the worst air pollution she has ever seen.It gave her husband a cough and left her sevenyearold daughter housebound(足不出户)．“My husband as well as I is working here，so we have no choice，” she said.“But if we had a choice，we'd like to escape from Beijing.”
The extended heavy pollution over the last month，which caused punishment in return for a day last week－called the “airpocalypse” by internet users－ has largely changed the way that Chinese think about the country's air.On one day，pollution levels were 30 times higher than levels considered safe by the World Health Organization (WHO)．Flights were cancelled.Roads were closed.One hospital in east Beijing reported they had treated more than 900 children for breathing issues.Bloomberg found that for most of January，Beijing's air was worse than that of an airport smoking area.
The smog's(烟雾) most threatening aspect is its high concentration(浓度) of PM 2.5 － particulate matter that is small enough to breathe deep into the lungs and enter the bloodstream，causing breathing infections，lung cancer and possibly damaging children's development.The WHO has estimated that outdoor air pollution accounts for two million deaths per year，65% of them in Asia.Which conclusion can we draw from the first paragraph?
| A．Hu Li is living in Beijing. |
| B．Hu Li traveled to Tianjin for business. |
| C．The haze is harmful to people. |
| D．The pollution is the worst in Beijing's history. |
The haze affected people mainly in________．
| A．the way they traveled |
| B．the opinion about national air |
| C．the way they lived their life |
| D．the life style of internet |
From the passage we know high concentration of PM 2.5________．
| A．can lead to choke |
| B．can cause heart cancer |
| C．will damage children's development |
| D．will damage people's organ |
What's the best title for the passage?
| A．Hu Li's attitudes to Beijing's haze |
| B．The damages of Beijing's haze |
| C．WHO suggests improving Beijing's air |
| D．What caused air pollution in Beijing |
The phenomenon is becoming more and more popular that human beings have developed a closely relationship with the most dangerous of animals－Kevin Richardson treats lions like kitty cats，Andre Hartman has a special bond with Great White Sharks and now there is 79year old Werner Freund who has spent the last 40 years of his life in the company of wolves.
While details about how and why the former paratrooper(伞兵) became attached to these beautiful wild animals are a little summary，he has been tending them in his 25acre Wolvespark located in the German province of Saarland，since 1972.While he currently has a group of 29，over the years he has raised almost 70 wolves belonging to all breeds(种属) ranging from Siberian to Arctic，Canadian，European and even，Mongolian.The wolves treat Werner as if he were one of their own.They nuzzle(依偎) against him，play with him and are generally sheeplike when he is around，just like they would be around a head wolf!
This，however，is not accidental－It is a position that Werner works on establishing and maintaining with a simple act，every single day－Whenever it's feeding time，he calls his wolves to come for the raw meat by howling.As the hungry animals rush to get their food，they are always met with this scene－Werner sinking his teeth into the raw meat first.While this may sound a little rude，that is how the position of hierarchy(等级) is established in the animal world.It is always the leader male that gets the first meal and only when he signals，can the rest join in.Werner's wolves know this rule quite well and never challenge his authority.
While wolves，the largest member of the dog family，are believed to be dangerous，they rarely attack humans.Werner says that in reality，they are beautiful gentle souls，whose reputation has been tarnished，by fairy tales like Red Riding Hood!We can know________from the first paragraph.
| A．all lions like Kevin Richardson |
| B．Great White Sharks are dangerous animals |
| C．only some specialists can live animals together |
| D．Werner Freund accompanies wolves day and night |
What's the best title of the passage?
| A．Human beings can get along well with animals |
| B．Werner Freund and his famous Wolvespark |
| C．Werner Freund treats his wolves like friends |
| D．Exparatrooper shares special bond with wolves |
We can infer that the wolves treat Werner Freund________．
| A．peacefully | B．respectfully | C．fearfully | D．fondly |
When Werner Freund feeds his wolves，________．
| A．he whistles loudly |
| B．he bites the meat firstly |
| C．wolves challenge his authority |
| D．wolves eat all their foods. |
