8．A recent study has found that the risk of dementia（痴呆） 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（多发性硬化）．
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．

18．With the coming of big data age，data science is supposed to be starved for，of which the adaption can point a profound change in corporate competitiveness．Companies，both born in the digital era and traditional world are showing off their skills in data science．Therefore，it seems to have been creating a great demand for the experts of this type．
Mr Carlos Guestrin，machine learning professor from University of Washington argues that all software applications will need inbuilt intelligence within five years，making data scientists-people trained to analyze large bodies of information-key workers in this emerging"cognitive"technology economy．There are already critical applications that depend on machine learning，a subfield of data science，led by recommendation programs，fraud detection systems，forecasting tools and applications for predicting customer behavior．
Many companies that are born digital-particularly internet companies that have a great number of real-time customer interactions to handle-are all-in when it comes to data science．Pinterest，for instance，maintains more than 100 machine learning models that could be applied to different classes of problems，and it constantly fields requests from managers eager to use this resource to deal with their business problem．
The factors weighing on many traditional companies will be the high cost of mounting a serious machine-learning operation．Netflix is estimated to spend﹩150m a year on a single application and the total bill is probably four times that once all its uses of the technology are taken into account．
Another problem for many non-technology companies is talent．Of the computer science experts who use Kaggle，only about 1，000 have deep learning skills，compared to 100，000who can apply other machine learning techniques，says Mr Goldbloom．He adds that even some big companies of this type are often reluctant to expand their pay scales to hire the top talent in this field．
The biggest barrier to adapting to the coming era of"smart"applications，however，is likely to be cultural．Some companies，such as General Electric，have been building their own Silicon Valley presence to attract and develop the digital skills they will need．
Despite the obstacles，some may master this difficult transition．But companies that were built，from the beginning，with data science at their center，are likely to represent serious competition．

63．Which one is obstacle for many traditional companies to popularize learning operation？C
A．Technological problem．
B．Expert crisis．
C．High cost．
D．Customer interactions．
64．What can not be inferred from the passage about the machine learning？D
A．Machine learning operations are costly in Netflix．
B．Machine learning plays an important role in existent applications．
C．Machine learning experts are not highly paid in some non-technology companies．
D．Machine learning models are not sufficient to solve business problems in Pinterest．
65．The underlined word in the 3rd paragraph"fields"most probably meansC．
A．avoids B．createsC．solvesD．classifies
66．Which of the following is the best title for this passage？A
A．Data science：a forefront force in tech business
B．Corporate competition：an obstacle to the transition
C．Machine learning：a key to smart technology
D．Technique experts：a decisive factor of the coming era．

5．Why does gratitude matter？Gratitude doesn't just feel good．（36）DLike other positive emotions，feeling grateful on a regular basis can have a big effect on our lives．Brain Research shows that positive emotions are good for ourbodies，minds，and brains．
Positive emotions help us see more possibilities and take in more information．They increase ourability to develop skills．（37）EPositive emotions balance negative emotions out．People who often feel grateful and appreciative are happier，less stressed，and less depressed．Gratitude is like a U-turn on complaining or thinking about what we don't have．
（38）BWhen we feel grateful，we might also feel happy，calm，joyful，or glad．
Gratitude can lead to positive actions．When we feel grateful for someone's kindness towards us，we may be more likely to do a kindness in return．（39）GThanking people can make it more likely that they'll do a kindness again．
（40）CWhen we feel and express heartfelt gratitude and appreciation to people in our lives，it creates loving bonds，builds trust，and helps you feel closer．
When we make it a habit to feel grateful and appreciative，it increases our awareness of good things as they happen．That set of attitude of gratitude has positive effects on our mood．

A．It might make you suffer a lot．
B．One positive emotion often leads to another．
C．Gratitude helps us build better relationships．
D．Making a habit of gratitude can also be good for us．
E．In addition，they help us to learn and make good decisions．
F．Find out who you appreciate and what the reasons might be．
G．Your gratitude also can have a positive effect on someone else's actions．

2．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!
