2．Do you sometimes put off doing your homework on a school night to watch TV？A new study says that middle school students who watch TV or play video games during the weekdays do worse in school．
The study also says that watching TV and playing video games on weekends don't affect school performance that much．
"On weekdays，the more they watched，the worse they did，"said Dr．Iman Sharif of Children's Hospital at Montefiore in New York．"They could watch a lot on weekends and it didn't seem to connect with doing worse in school．"
The study appears in October issue of Pediatrics．Researchers drew their conclusions after surveying 4，500students in New Hampshire and Vermont middle schools．
To reach their findings，researchers didn't look at grades or test scores．Instead，they asked students to rate（評價） their own performance on a scale ranging from"excellent"to"below average"．
Other studies have found a connection between kids'ability to learn and the amount of TV they watch．One study even found that kids with televisions in their bedrooms scored about eight points lower on math and language arts tests than kids without．
What should a kid do？The American Academy of Pediatrics recommends that kids watch TV no more than two hours and that televisions be kept out of children's rooms．Weekends viewing should be kept to four hours at most each day．

68．The passage mainly talks about the relationships betweenB．
A．TV watching and students'character training
B．TV watching and students'school performance
C．students'communicating skills and TV watching
D．kids'mental development and TV watching
69．What can be concluded from the passage？B
A．Kids can watch TV as long as they wish on the weekends．
B．Kids can watch TV longer on the weekends than on weekdays．
C．Kids should not be allowed to watch TV on the weekends．
D．Kids can watch TV during the weekdays in their rooms for a long time．
70．The purpose of keeping televisions out of children's room is toC．
A．protect the TV sets from being broken by kids
B．prevent the kids from playing video games on TV
C．limit the time of TV the kids watch
D．provide the kids with the quietness they need to study
71．Who is likely to have excellent school performance according to the passage？D
A．A student putting off doing homework on a school night to watch TV．
B．A student who watches TV 4hours a day．
C．A kid who has TV set in his own room．
D．None of the above．

4．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．
Roosegaarde 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 proven the results of the device both indoors and outdoors
C．the results of the air-cleaning device can be expectable
D．the Beijing government has 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．

It was a winter morning, just a couple of weeks before Christmas 2005. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually did. After putting in 10 hours of labor, he returned to find his bike gone.

The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries（食品雜貨），saving us from having to walk long distances from where we live.

I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.

People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity（人性）as a whole. And it has influenced（影響）us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.

1.Why was the bike so important to the couple?

A. The man’s job was bike racing.

B. It was their only possession.

C. It was a nice Kona 18 speed.

D. They used it for work and daily life.

2.We can infer from the text that ____________.

A. the couple worked 60 hours a week.

B. people were busy before Christmas

C. the stranger brought over the bike

D. life was hard for the young family.

3.What do the couple learn from their experience?

A. Strangers are usually of little help.

B. One should take care of their bike.

C. News reports make people famous.

D. An act of kindness can mean a lot.

4.Which one do you think is NOT TRUE according to the text?

A. The couple will never steal bikes in revenge.

B. The couple will try their best to help others in trouble.

C. Trevor bought a new Kona immediately after someone stole his old one.

D. The couple got some help from several people in their area.

As has been all too apparent in recent days at Balcombe, few issues cause greater concern than energy policy. Many village communities feel their countryside is being ruined by the power-producing machines of wind farms; yet they never take “ direct action”, even though the planning laws put them at a severe disadvantage. And the generous subsidies(財政補(bǔ)貼),which encourage the expansion of wind power, are not favorable to the village communities and set landowners in conflict with other residents.

Those who disagree with the rapid expansion of wind farms state that the damage they cause is out of proportion to the benefits they bring, because their energy output cannot match that of the carbon-based power stations they are supposed to replace. Supporters insist that wind must be part of a mix of renewables, nuclear and carbon, and that the country is committed to meeting EU(European Union) targets for non-carbon energy generation.

Against this background, the fact that there is an argument within the Government over whether to publish an official report on wind farms impact on the countryside becomes even more extraordinary. The two parties in the coalition government are in disagreement over what it should say.

We have some advice for the two parties :publish the report ,and let the country be the judge. Even if it contains evidence that wind farms are harmful, it will hardly be a pleasant surprise to people who do not like them. Equally, supporters must argue their case by acknowledging the concerns and explaining why they are either misplaced or worthy of much attention.

The suggestion that further negotiations are to take place to produce an “acceptable” report suggests that the politics of coalition government are doing the country harm in a certain way. Given the sensitivities involved ,all the information should be available so that people can reach their own conclusions, rather than being left with the suspicion that facts are being replaced by political beliefs.

1.We call learn from the first paragraph that________.

A. energy policy catches much attention of the public

B. the residents are in favor of the expansion of wind farms

C. many village communities are satisfied with the subsidies

D. the planning laws offer great benefits to the residents

2.Supporters think that the expansion of wind power_____.

A. is more rapid than that of carbon-based power

B. guarantees an increase in energy output

C. is expected to be much better than that of nuclear Dower

D. agrees with EU targets for non-carbon energy generation

3.It can be inferred from the passage that_________.

A. an official report will settle the energy problem

B. the two parties are divided over the issue of wind farms

C. the two parties have agreed on a further negotiation

D. political beliefs concerning energy issue go against facts

4.Which of the following reflects the author’s opinion?

A. Increase political impact on energy policy.

B. Release a statement of supporters on wind farms.

C. Let the nation judge the facts about wind power.

D. Leave the two parties to reach their own conclusions.

14．Scientists have found we are more likely to die on our birthday than any other day．Researchers who studied more than two million people over 40years found a rise in deaths from heart attacks，strokes（中風(fēng)），falls and suicides（自殺）and others on that day．
On average，people over the age of 60were 14per cent more likely to die on their birthdays．Heart attacks rose 18.6per cent on birthdays and were higher for men and women while strokes were up 21.5per cent-mostly in women．
Dr Vladeta Ajdacic of the University of Zurich said："Birthdays end dangerously more frequently than might be expected．"He added that risk of birthday death rose as people got older．
Canadian data also showed that strokes were more likely on birthdays，especially among patients with high blood pressure．
There was a 34.9per cent rise in suicides，28.5per cent rise in accidental deaths not related to cars，and a 44per cent rise in deaths from falls on birthdays．
Psychologist Professor Richard Wiseman，from the University of Hertfordshire，said，"It seems to be a reliable finding．There are two cases-one is the case that suggests you eat too much and your getting over excited and that causes you to die．"He said continuously，"The other is a placebo effect（安慰劑效應(yīng)）．You are knife-edged on death．And you kept yourself going until your birthday．You think‘That's it．I've had enough．I'm out of here．'"
Dr Lewis Halsey，of the University of Roehampton，said，"One interesting finding is that more suicides happen on birthdays，though only in men．Perhaps men are more likely to make a statement about their unhappiness when they think people will be taking more notice of them．"

59．Which sentence can properly be put at the beginning of the passage？D

12．Driving in traffic can be extremely stressful．Pedestrians appear out of nowhere，cars suddenly pull out of parking spots，and roads become slippery due to rain or snow．Knowing when to brake and when to accelerate in such situations is hard enough for a human driver，let alone a robotic one．But several carmakers-and a few tech companies-are working to convince drivers to let driverless cars take the wheel．
       Without question，the most anticipated benefit of driverless cars is improved safety．Driverless systems will feature sensors that detect safety threats that human drivers might miss．Many carmakers already offer systems that alert drivers whenever they get dangerously close to other cars．
Also，driverless systems have the benefit of increased efficiency．Driverless cars won't waste as much gas as human drivers do，and guided by advanced GPS，they'll always take the fastest route．Once driverless cars become widely available，common people can have their own driver，and they'll just sit back and relax while their car's computer takes the wheel!
Although completely driverless cars won't be on the market for several years，the technology behind them is already appearing in phases．Two examples are the Active Lane Keeping Assist option for Mercedes-Benz cars and Ford's Traffic Jam Assist．In the first option，the system warns the driver whenever the car crosses lane markings by causing the steering wheel to vibrate（振動）．In the second option，the system helps the car keep pace with other cars while remaining in its current lane．The system is being developed to help relieve blocking on busy roads．
       Several carmakers claim that they'll produce driverless cars within the next decade．But critics aren't so sure，warning that a completely driverless car must be able to make split-second decisions in even the most complex traffic situations．In addition，the car's computer must become smart enough to know when to ask the driver to intervene （介入，干涉） to prevent an accident．
       Full government approval won't happen until driverless cars are proven safe．In the meantime，expect to see carmakers offer ever-smarter features on their new models．
 （Note：Answer the questions or complete the statements in NO MORE THAN TWELVE WORDS）
78．One of the factors that make traffic extremely stressful is thepedestrians appearing out of nowhere/cars pulling out of parking spots/slippery roads due to rain or snow
79．What are the benefits of driverless system？Improved safety and increased efficiency
80．What will happen to a car with the Active Lane Keeping Assist when it crosses lane markings？The steering wheel will vibrate．
81．Driverless cars won't be on the market until they canmake split-second decisions and know when to ask the driver to intervene．
