Every four years on November 8, the American people will vote for the next U. S. president. Before election day, people following the presidential campaign will see many polls (民調(diào)). A poll is a public opinion study. Research organizations ask people questions about the candidates to find out who they support.

For example, one of the poll is run by a professor at a university in the U.S. state of Connecticut. People who work for the polling service call likely voters on the telephone.

How can one poll be so different from others? Here are some things to remember when you are looking at polls:

Not all polling groups are the same

Some polls target specific groups of people. Many polls make sure they collect many different opinions. Sometimes, however, polling organizations receive money from groups that support a specific political issue. It is important to look at which group carried out the poll along with the results.

A poll's method is important

Some polls are using new technology. Traditionally, polls are done over the phone. But that is slowly changing. Many polls are now done online. While online polls can produce good information, it is sometimes hard to reach as many different types of people over the Internet.

Also important the size of the poll. Try to find out how many people were polled before believing its results.

Polls are not predictions(預(yù)測(cè))

Polls only show how people feel at one moment in time. They do not show what will happen in the future. Public opinion may change before the general election on November 8. Some things that could change the opinions of voters include: the debates on television, the release of the candidates’ tax or medical records, and unexpected illnesses.

1.What do political polls in the U. S. try to do?

A. Call on people to be active in the election.

B. Help political parties to win the election.

C. Find out the support rate in the election.

D. Affect people's opinions in the election.

2.What do you know about polling organizations?

A. Some serve for certain groups. B. They all collect different opinions.

C. They all make money from their polls. D. All of them try to find the correct results.

3.What is the disadvantage of polls done online?

A. People may refuse to respond. B. Results sometimes lack of representation.

C. Only the young give their ideas. D. People refuse to tell their true thoughts.

4.What can be a suitable title for the text?

A. Effects of Political Polls in the U. S..

B. Various Kinds of Political Polls in the U. S..

C. Ways to Carry Out Political Polls in the U. S..

D. Things to Know About Political Polls in the U. S..

3．A Dutch artist and designer has come up with a device which he hopes will get rid of pollutants from Beijing's smog skies，creating clean air for the city's mask-wearing people．An electromagnetic （電磁）field will pull particles（微粒） in the smog to the ground where they can be easily cleaned．"
It's like when you have a balloon which has static（靜電） and your hair goes toward it．Same with the smog，"says artist Daan Roosegaarde．
His studio has reached an agreement with the Beijing government to test the technology in one of tile capital's parks．
With its skies regularly covered by dirty gray smog，Beijing this week announced a series of emergency measures to handle the problem．
Roosegarde says an indoor model device has already proven it works and is confident that the results-with the help of a team of scientists and engineers-can be replicated outside．
"Beijing is quite a good place because the smog in Beijing is quite low．It lies in a valley so there's not so much wind．It's a good environment to explore this kind of thing．"
"We'll be able to purify the air and the challenge is to get the top of the smog so you can see the sun again．"
Roosegaarde acknowledges that projects like this are a way of drawing attention to the problem，rather than a practical solution to Beijing's awful air pollution．
"This is not the real answer for smog．The real answer has to do with clean cars，different industry and different lifestyles．"
However，he hopes the project will make a"fundamental statement"by allowing the city's people to realize the difference between breathing clean and smog-filled air．

25．The device works byB．
A．helping keep the particles out with more masks
B．pulling pollutants to the ground with an electromagnetic field
C．a(chǎn)bsorbing hair with a balloon with static
D．creating clean air and let it out into the sky
26．According to the passage，C．
A．the Beijing government has agreed to use the technology in Beijing
B．they have provn the results of the device both indoors and outdoors
C．the results of the air-cleaning device can be expectable
D．the Beijing governmenthas never done anything to handle the air pollution
27．What does Roosegaarde really mean by saying"Beijing is quite a good place…"？C
A．The air pollution in Beijing is not quite serious．
B．The weather in Beijing is good for foreigners to live in．
C．Beijing is quite fit for using the air-cleaning device．
D．It is easy to get the top of the smog in Beijing．
28．Roosegaarde appeals to people in Beijing toA．
A．pay attention to air pollution and solve the problem finally
B．invent more devices to clean the smog in Beijing
C．drive modern cars and try different lifestyles
D．realize how serious the pollution they're facing is．

20．Repeated exposure to social networking sites leaves users with an‘‘identity crisis"，wanting attention in the manner of a baby saying，'‘Look at me，Mummy，I've done this．"
Professor Baroness Greenfield believes the growth of internet"friendships"，as well as greater use of computer games，could effectively‘'rewire"the brain，
This can result in reduced concentration，a need for instant satisfaction on poor non-verbal skills，such as the ability to make eye contact during conversations．
More than 750million people across the world use Facebook to share photographs and videos and post regular updates of their movements and thoughts．Millions have also signed up to Twitter，the"micro-blogging"service that lets members circulate short text and picture messages about themselves．
Baroness Greenfield said，"What concerns me is the banality of so much that goes out on Twitter，"Why should someone be interested in what someone else has had for breakfast？It reminds me of a small child saying，"Look at me Mummy，I'm doing this"，"Look at me Mummy，I'm doing that"．
"It's almost as if they're in some kind of identity crisis．"The academic suggested that some Facebook users feel the need to become"mini-celebrities，"who are watched and admired by others on a daily basis．They do things that are"Facebook worthy"because the only way they can define themselves is by people knowing about them．
"It's almost as if people are living in a world that's not a real world，but a world where what counts is what people think of you or （if they） can click on you，"she said．
"Think of the implications for society if people worry more about what other people think about them than what they think about themselves．"
Her views were supported by Sue Palmer，a literary expert and author，who said girls in particular believe they are"goods they must sell to other people"on Facebook．
She said．"People used to have a portrait painted but now we can more or less design our own picture online，it's like being the star of your own reality TV show that you create and put out to the world．"
59．People who often use Facebook and Twitter willD．
A．develop strong online friendship with other users
B．improve their ability to focus their attention on things
C．develop non-verbal skills to communicate with each other
D have a childlike desire for constant feedback on their lives
60．The underlined word"banality"in the passage may mean something that isA．
A．dull 
B．interesting 
C．important 
D．serious
61．The purpose of the passage isA．
A．to advise people to use less social networking
B．to warn people not to be cheated on Facebook
C．to introduce the functions of Facebook and Twitter

You don't need superpowers to commit to being healthier.Check out these tips.

Write it and measure it.1.Writing down your goals is not only a great way to accomplish them,but your list can also help you figure out the exact steps needed to get there."I want to lose weight"is a pretty common resolution（方案）,but how exactly do you go from point A to point B?2.For instance:"I want to lose 10 pounds over the next six weeks by going to the gym three to four times per week."

Make resolutions manageable.A resolution shouldn't be a fantasy.The key to sustainable resolutions is to make small changes gradually.So if your goal is to go from never running to finishing a half-marathon,start training gradually.3..

4.Not knowing how to do a certain exercise is no excuse to write it off completely.If you're curious about new techniques,book a session with a personal trainer to clear up confusion and help prevent injury.

Think outside the box.5.If your resolution is to simply be more active and bum more calories every day,there are plenty of creative ways to achieve that goal.You can fit extra movement into the day by walking during phone conversations or even volunteering for household chores.

A.Ask for help．

B.Choose the right tech.

C.Instead,try setting a more specific goal.

D.Exercise doesn't have to be a formal activity.

E.Resolutions should be both specific and measurable.

F.Begin by walking a few miles,and steadily increase it to jogging,and then running.

G.The reason is that the brain just likes measurable old habits over new,different ones.
