8．A recent study has found that the risk of dementia（癡呆） can increase if people live near a main road．According to the research，waste gas and noise from a busy road lead to one in ten dementia deaths of the 6.6 million patients investigated．
Air pollution is already known to contribute to the deaths of around 40，000 people in Britain each year by worsening breathing and heart conditions，while previous research showed emissions （排放物） can cause brain shrinkage．But the new study by Canadian public health scientists is the first to find a link between living close to heavy traffic and the increasing of dementia，a discovery described as"believable"and"impressive"by British experts．
Dr Hong Chen said．"Our study suggests that busy roads could be a source of environmental stressors that could give rise to the onset of dementia．Population growth and urbanization has placed many people close to heavy traffic，and with widespread exposure to heavy traffic and growing rates of dementia，even a modest effect from near-road exposure could cause a large public health burden．More research to understanding this link is needed，particularly into the effects of different aspects of traffic，such as air pollutants and noise．"
In the new study，the team tracked all adults aged between 20 and 85 living in Ontario for more than a decade from 2001 to 2012．They used postcodes to determine how close people lived to a main road and analyzed medical records to see if they went on to develop dementia，Parkinson's disease or multiple sclerosis（多發(fā)性硬化）．
While there was no correlation between living near a road and Parkinson's disease or multiple sclerosis，
dementia risk reduced as people lived further from a main road，with a 7 percent higher risk in developing dementia among those living within 50 metres； a 4percent higher risk at 50-100 metres and a 2 percent higher risk at 101-200 metres．After 200 metres there was no increase．Researchers believe that noise of traffic may also play a role in the raised risk as well as other urban pollution，which is often present near busy roads．

28．What can we know about Canadian's new study？C
A．British experts think highly of it．
B．It brings benefits to dementia patients．
C．It shows that air production is very serious．
D．It shows that air pollution can cause brain shrinkage．
29．What Dr Hong Chen said showed thatD．
A．people are diagnosed with dementia mainly due to air pollution
B．widespread exposure to traffic will reduce the risk of having dementia
C．the link between living near roads and having dementia was not obvious
D．busy roads could be a source of environmental stressors that caused dementia to increase
30．What does the underlined the word‘correlation'mean？B
A．Change．
B．Improvement．
C．Affection．
D．Secret
31．What can be inferred from the last paragraph？A
A．Living near a main road adds to the risk of noise．
B．Living beyond 300metres of a main road is safe for people．
C．Living within 200metres of a main road has a lower risk of having dementia．
D．The further people live away from heavy traffic，the smaller the risk of having dementia．

分析 文章主要講了城市的交通噪音引發(fā)了很多疾�。�

解答 28．C 細節(jié)理解題．根據(jù)文章內(nèi)容Air pollution is already known to contribute to the deaths of around 40，000 people in Britain each year by worsening breathing and heart conditions，據(jù)了解，空氣污染每年導致英國約40000人死亡，原因是呼吸和心臟狀況惡化．故選C．
29．D 細節(jié)理解題．根據(jù)文章內(nèi)容．"Our study suggests that busy roads could be a source of environmental stressors that could give rise to the onset of dementia．Population growth and urbanization has placed many people close to heavy traffic，and with widespread exposure to heavy traffic and growing rates of dementia，even a modest effect from near-road exposure could cause a large public health burden．More research to understanding this link is needed，particularly into the effects of different aspects of traffic，such as air pollutants and noise．"我們的研究表明，繁忙的道路可能是導致老年癡呆癥發(fā)病的環(huán)境壓力源．"人口增長和城市化使許多人接近繁忙的交通，并廣泛接觸交通擁擠和癡呆率的增長，即使是近距離道路暴露的輕微影響也會造成很大的公共衛(wèi)生負擔，需要更多的研究來了解這一聯(lián)系，特別是交通的不同方面，如空氣污染物和噪音的影響．"故選D．
30．B 詞義猜測題．根據(jù)文章內(nèi)容While there was no correlation between living near a road and Parkinson's disease or multiple sclerosis，雖然住在公路附近和帕金森氏病或多發(fā)性硬化癥沒有相關(guān)性，但通過后文得知也做出了一定的改變．故該詞在文章中的含義為改進．故選B．
31．A 細節(jié)理解題．根據(jù)文章內(nèi)容Researchers believe that noise of traffic may also play a role in the raised risk as well as other urban pollution，which is often present near busy roads．研究人員認為，交通噪音也可能對增加的風險以及其他城市污染造成影響，而城市污染往往是在繁忙的道路上出現(xiàn)的．故選A．

點評 做這類題材閱讀理解時要求考生對文章通讀一遍，做題時結(jié)合原文和題目有針對性的找出相關(guān)語句進行仔細分析，結(jié)合選項選出正確答案．推理判斷題也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確答案，切忌胡亂猜測，一定要做到有理有據(jù)．

18．It is often assumed that girls and boys me genetically determined from birth to develop in different ways．Scientific studies have actually found that there are more similarities than differences when it comes to how  girls and boys develop mentally and how they learn new skills．However，on the whole，girls are more likely to be tailkative，self-motivated，able to understand other people's feelings，and likely to have better verbal （言語的）skills，which help them with reveling and writing，Boyst on the other hand，are more likely to be competitive and less able to understand others'feelings．However?they tend to develop superior spatial （空間的）skills which help with maths and science．

Some schools believe that a mule presence-whether it is a male teacher or more involvement from dad at home-is a key factor in motivating boys and improving their grades．Others advocate a more"boy，friendly"environment at school whether it's stocking more books in the library that appeal to boys or trying out different teaching styles in lessons to engage boys in learning．
Your child's education doesn't just stop in the classroom．You played central role in their learning development before they went to school and you'll continue to be a primary role model throughout their school years．
If your children are primary-aged and struggling with reading or writing，ask their class teacher how you can best help your child．Perhaps their teacher could recommend some short，fm activities you could do together at home or a selection of suitable and appealing books you could read with your child．
If your child is at secondary school and Jailing with all the normal teenage anxieties on top of struggling with their studies*they may just tell you they don't want to talk about it．Explain that you also found some subjects difficult and you want to help if you can．Again，lots of encouragement can go a long way．
But if you feel you're not the best person  to talk to your teenage son or daughter about their school work．a(chǎn)sk for help from someone else your child trusts-this might be a teacher they like，a close family friend or a  relative．

19．Free Wi-Fi has become very important to us：many stores and shopping malls offer it，restaurants use it to attract customers，and for libraries and coffee shops it is a must-have service．
Even when people are traveling，they scan for free Wi-Fi．When selecting or rating a hotel，six in ten travelers believe that unlimited Wi-Fi is the most important factor．
"Today，people will never forget to pack their smart phones，tablets and laptops into the suitcase，"said the Daily Mail．"We rely on free Wi-Fi heavily when traveling-especially when it comes to checking social media，checking out travel tips，and accessing websites．"
However，despite the opportunities that free Wi-Fi gives us，"our over-reliance on technology has come at a price，with travelers feeling unable to escape social media"，said Lonely Planet，the world's largest travel guide brand．
Anita Isalska，Lonely Planet editor and tech addict，was forced to unplug when in an isolated （隔絕的）camp in Greenland recently．"Adjusting to this slower pace，I began to realize that：social media had changed into a habit，"she wrote．"I had believed I was capturing （捕捉） moments，but in reality my busy fingers were preventing me enjoying travel's deepest pleasures．How fully can you appreciate a huge glacier or wild flowers when your brain is selecting the right photo filter （濾鏡） or the perfect six seconds to take photos"
In September，Lonely Planet released 10predictions for the future of global travel．One of them was that true escapes will be highly valued in future，so remote hotels will start to make their lack of the Internet into an appealing feature．Would you like to have an unplugged holiday？

28．According to the passage，people nowadays tend to do the following EXCEPTD．
A．getting out of a library that has no access to the Internet
B．thinking ill of a hotel without Wi-Fi
C．making travel plans via the Internet
D．enjoying travelling without Hi-Tech equipment
29．Through the fourth paragraph，the author intends toB．
A．give more evidence to the view mentioned
B．show a different opinion on the topic
C．get into another topic
D．summarize the previous paragraphs
30．What has Anita Isalska realized in Greenland？C
A．Travelers cannot survive without Hi-Tech．
B．Taking pictures doesn't affect appreciating nature．
C．Her over-reliance on technology has come at a price．
D．Her fingers are not flexible enough to take enough pictures．
31．What does"an unplugged holiday"mean in the last paragraph？C
A．A camping holiday．
B A holiday in a remote hotel．
C．A holiday without Wi-Fi．
D．A holiday without taking pictures．

16．I'm part of the Roots & Shoots program founded by Dr．Jane Goodall．The program is intended to make and promote positive changes in the world．As Dr．Goodall says，"What you do makes a difference，and you have to decide what kind of difference you want to make．"
In Bulgaria，where I live，homeless dogs are everywhere．Many people here turn a blind eye to them．But I cannot ignore the life of a street dog whenever I see one wandering in the street，looking for something to eat．That's why I'm no longer a food waster．When I see wasted food，I always think of a hungry dog climbing to garbage bins，searching for food that people have thrown there．When eating in a restaurant，I'm not afraid to take leftover food to feed stray cats or dogs．
A week ago，I saw a homeless dog around the garbage bins．Immediately I knelt down，spoke to her softly and ran my hands over her．I could see that she had had puppies．I couldn't imagine how she could have been able to care for them．Hours earlier，I'd bagged up a plate of leftover fish．As I unwrapped it，she wagged her tail and sniffed at it．She ate all the fish in no time．
It's sad，isn't it？I can't understand why many of us waste so much and think little of it．These homeless animals have taught me that food is precious．Even when I don't have leftovers with me，I'll take the time to get something from the grocery store to feed them．
I know my power is small，so I hope that next time you see wasted food，do turn it into worthy food．You have the power to save a life!

21．The author uses what Dr．Goodall says to showD．
A．how we can develop our business
B．why it is important to be great
C．why the program is popular globally
D．how we can change the world positively
22．What can be concluded from the text？C
A．There are few homeless dogs where the author lives
B．The author takes homeless dogs home and raises them
C．Seeing homeless dogs makes the author never waste food
D．People throw food into garbage bins to feed homeless dogs
23．The author took the leftover fish with him toB．
A．eat it when he was hungry
B．feed a homeless dog he met
C．look for more homeless animals
D．set an example to those who throw away food
24．The author wrote the text to ask us toC．
A．value our food                    
B．treat dogs as our friends
C．save wasted food for homeless dogs   
D．raise homeless dogs and cats．

20．Bicycle Sharing
Foryears，bike-sharing plans have been common in big cities around the world，including in China．Examples include Paris's Vélib and London's Santander Cycles （"Boris bikes"）．But these require customers to return the bicycles to docking stations （泊車位）．In China，a more user-friendly approach is spreading rapidly．It involves bikes that can be paid for using a smartphone and left anywhere．GPS tracking enables them to be located with a mobile app．A ride typically costs only one yuan（﹩0.15）on a bike in an eye-catching colour．
The first such service was launched in June 2015 by a startup called Ofo．The company now has around 2.5m yellow-framed bikes in more than 50 cities in China．Its main rival，Mobike，which started up only a year ago，says it has"several million"of its orange-wheeled bikes spread across a similar area．Bluegogo has half a million bikes in six Chinese cities．It plans to add a new city every two weeks．
However，the dockless system is easy to abuse．Some riders hide the bikes in or near their homes to prevent others from using them．Another trick involves scratching off a bike's QR code to stop others from scanning it．A bigger problem for the new firms is persuading people to use bikes instead of cars．Thirty years ago，63% of Beijingers cycled to work．Now，only 12% do．Many people think that cycling is only for the poor．A dating-show contestant famously said in 2010 that she would"rather cry in a BMW than smile on a bike．"Cycling is also dangerous．About 40% of road accidents involve bicycles，according to a report in 2013．Some city authorities accuse the bike-sharing firms of causing congestion．This month，the southern city of Shenzhen ordered limits on the number of shared bikes．Other cities，including Shanghai and Beijing，are considering similar measures．
Despite some disadvantages，such user-friendly services represent the kind of green innovation that China wants and may even bring"a revolution"．
