11.XI'AN-China has introduced various emergency responses and longterm measures against air pollution in the central and eastern regions.
The air quality index (AQI) for Xi'an reached 500on Wednesday afternoon,at the top of the AQI scale,according to the national air quality monitoring website.Xi'an weather forecasters predict the smog (雾霾) will continue for the next week and air pollution may worsen.
"I have to keep buying masks for my family,"said Liu,buying masks at a pharmacy (药店) near her home in downtown Xi'an."This is the only thing we can do to protect ourselves."
On Wednesday,a city government emergency response plan was put into action,suspending all the construction and taking at least 50percent of government vehicles off the road.Power plants must limit their output and reduce emissions.
Nearly half the country,more than 100cities in 20provinces,has suffered from smog since last December.Many have taken action,including experimenting with artificial methods to reduce smog,limiting vehicle use and fining polluters.
Assessments based on GDP alone were abandoned last month and more emphasis has been put on public wellbeing and the environment.Whether the move will be effective in forcing local governments consider environmental issues over economic growth remains to be seen.Environmental protection professionals are doubtful about the immediacy of the effects of these measures.
Xiao Hang,an urban researcher at the Chinese Academy of Sciences,said it took London 50years to lose the moniker (绰号)"foggy London town"and Los Angeles still struggles to control its photochemical (光化学) smog.""We can't ignore environmental problems during the development process and China has a long way to go."he said.

A.AQI for Xi'an reached 500.
B.Smoggy Chinese cities to clear the air.
C.Smog crisis tries the limits of people's patience.
D.Dust masks become hot sellers.
42.The underlined word"suspending"in Paragraph 4can be replaced by"C".
A.encouraging       
B.continuing      
C.stopping        
D.expanding
43.We can infer from the article thatA.
A.assessments based on GDP alone were harmful to environmental protection
B.environmental professionals believe the air quality will soon be improved with these  measures
C.China is the only country suffering from smog
D.Xi'an was the most polluted city in China
44.What Xiao Hang said indicatesA.

B.the development of China is more important
C.London still has serious air pollution after 50years of effort

2.Your house may have an effect on your figure.Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off.You can make your environment work for you instead of against you.Here are some ways to turn your home into part of diet plan.
Open the curtains and turn up the lights.Dark environments are more likely to encourage overeating,for people are often less self-conscious(难为情)when they're in poorly lit places-and so more likely to eat lots of food.If your home doesn't have enough window light,get more lamps and flood the place with brightness.
Mind the colors.Research suggests warm colors fuel our appetites.In one study,people who ate meals in a blue room consumed 33percent less than those in a yellow or red room.Warm colors like yellow make food appear more appetizing,while cold colors make us feel less hungry.So when it's time to repaint,go blue.
Don't forget the clock-or the radio.People who eat slowly tend to consume about 70fewer calories(卡路里) per meal than those who rush through their meals.Begin keeping track of the time,and try to make dinner last at least 30minutes,And while you're at it,actually sit down to eat.If you need some help slowing down,turn on relaxing music.It makes you less likely to rush through a meal.
Downsize the dishes,Big serving bowls and plates can easily make us fat.We eat about 22percent more when using a 12-inch plate instead of a 10-inch plate.When we choose a large spoon over a smaller one,total intake(摄入) jumps by 14percent.And we'll pour about 30percent more liquid into a short,wide glass than a tall,skinny glass.

25.The text is especially helpful for those who care aboutB.
A.their home comforts
B.their body shape
C.house buying
D.healthy diets
26.A home environment in blue can help peopleB.
A.digest food better
B.reduce food intake
C.burn more calories
D.regain their appetites
27.What are people advised to do at mealtimes?C
A.Eat quickly.
B.Play fast music.
C.Use smaller spoons.
D.Turn down the lights.
28.What can be a suitable title for the test?A
A.Is Your House Making You Fat?
B.Ways of Serving Dinner
C.Effects of Self-Consciousness
D.Is Your Home Environment Relaxing?

3.The Oscar nominations (提名) will be announced tomorrow morning and despite the Academy's best efforts,it looks like the biggest films of the year will be mostly shut out of competition.Don't expect big nominations for The Avengers,The Dark Knight Rises or The Hunger Games.
Since 2008,the Academy of Motion Pictures Arts and Sciences (AMPAS) has been playing with the scheme for Best Picture in the hopes of getting more popular films nominated (提名) and increasing audience for the Oscar ceremony which last year was watched by fewer people than watched the Grammy Awards.First they increased the number of nominated films from five to ten.This year,to complicate things,there could be as many as ten nominees or as few as five.In order to qualify for a Best Picture nod,a film has to be the top pick of at least 5% of the Academy voters.
That means there's room for an unknown factor.Our in-house film expert,Mark Hughes,thinks that could be Skyfall or The Hobbit which would ruin the condition of this post.I think  Skyfall has a decent chance of being a spoiler.It has a admirable director in Sam Mendes,it's earned almost universal praise from critics and it's the first Bond movie ever to bring in 1billionattheboxoffice.ButIsuspectwe'regoingtoseeaveryblockbuster(大片)-lightlistofnominations.ThefilmsthataregettingthemostawardareLincoln,LesMiserablesandZeroDarkThirty.WhileLincolnandLesMizaredoingwellattheboxoffice(earning144million and 172millionsofarseparately),theyaren'tnearthetopearnersof2012.ZeroDarkThirtyhasonlybeenplayinginafewtheaters.Itexpandsintowidereleasethisweekend.It'snotnecessarilyabadthingthatbigblockbustersdon'tgetnominated.Filmsthatearnover1billion at the box office don't really need any more publicity or anything else to help increase DVD income.Smaller films,like Zero Dark Thirty,rely on that Oscar boom.Nominations focusing on smaller films is good for the overall Hollywood ecosystem,even if the people running the awards would like to make things interesting a bit.
The awards are scheduled for February 24th on ABC.Seth MacFarlane is this year's host.

63.The AMPAS made changes to Best Picture toC.
A.attract more people to watch movies
B.keep the biggest films away from it
C.make the Oscar ceremony more popular
D.increase the number of popular movies
64.The underlined part"Skyfall has a decent chance of being a spoiler"(in Paragraph 3)meansB.
A.Skyfall is the best Bond movie
B.Skyfall is quite likely to be nominated
C.Skyfall is just so-so
D.Skyfall has little chance to be nominated
65.Nominations focusing on smaller films is in the hope thatB.
A.smaller films are better than those so-called blockbusters
B.more people will go to see smaller films
C.blockbusters needn't any nominations
D.blockbusters will have better environment
66.There is a room for an unknown factor in the nominations this year becauseB.
A.the film has to be selected by at least 5% of the Academy voters
B.there could be five to ten nominees
C.the biggest films will be mostly shut out of competition
D.The Hobbit would ruin the condition of this post.
