A decade-long study, also the first major research into air pollution and disease has shown that living near a main road increases the risk of dementia(癡呆). The study of 6.6 million people found that one in 10 dementia deaths in people living within 50 metres of a busy road was due to waste gas and noise. 

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 4 percent 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.

Many scholarships require that you write an essay in order to be considered for the prize money. However, if you are the sort of person that has a headache whenever you have to complete a writing assignment, this may not be the best news. Luckily for you, there is no reason to fear the scholarship essay. The following tips could help you conquer this not-so-easy aspect of the scholarship application process.

You should always outline your essays. This does not just apply to the scholarship essays, either. An outline helps lend focus to your thoughts and helps you create a picture of the “whole” that the essay will become. Judges cannot to stand when your writing is loose, lacks coherence(連貫性)or when you fail to connect your main points together. They want to see that you can support your argument well with clear and brief examples and that these examples do, in fact, relate to the topic at hand.

If you have a choice in the topic you get to write about, always try to select something you are personally interested in. Don't write what you think the judges want to hear. This will only amount in an essay that reads like someone else’s, which is not a great way to make yourself stand out.

If you feel bored with the topic, then your essay will be boring as well. Make sure your idea follow a clear and a logical path. This means they are connected well and the transitions(過(guò)渡) easily flow from one idea to the next. Likewise, try to stay away from the obvious or the sad story. Yes, college will be a life-changing experience, but can you think of an interesting reason why this is so? And yes, it is terrible that you lost a family member at a young age, but what does it have to do with winning this scholarship? Judges can smell sad stories from a mile away, so only pull at the heartstrings(動(dòng)人心弦) if you have a proper reason for doing so.

While being lost in the woods can be a frightening experience, surviving alone in the wild is generally a matter of common sense, patience, and wisely using the gifts that nature provides.1..

Do your research first. Don't just trek off into the wilderness; get a solid understanding of your surroundings first. Studying a map of the area where you're going -- and making sure to bring it with you -- will increase your chances of not getting lost tremendously. Educate yourself about the flora and fauna of the area you are exploring. 2..

3.. A cell phone with a spare battery or a portable CB radio can be your best, quickest means of rescue if you are truly lost or injured. A cell signal may only be obtainable only from a hill or tree, but is better than nothing. Serious hikers may even consider investing in a personal locator beacon such as the SPOT Messenger for extended, precarious, or very remote, treks.

Don't panic if you’re lost. Panic is more dangerous than almost anything else, because it interferes with the operation of your single best, most useful and versatile survival tool: your mind. The moment you realize that you are lost, before you do anything else, stop.4.. Before you act, follow the idea of STOP: S = sit down T = think　O = observe your surroundings P = prepare for survival by gathering materials.

Signal your location. Make noise by whistling, shouting, singing, or banging rocks together. 5. . If you're in a mountain meadow, make three piles of dark leaves or branches in a triangle. In sandy areas, make a large triangle in the sand. Three of anything in the wilderness is a standard distress signal.

A. Bring a means of communication.

B. If you can, mark your location in such a way that it's visible from the air.

C. Knowledge of the local plants and animals can save your life

D. If you want to know how to survive in the woods, just follow these steps.

E. Starvation won't be a big problem.

F. Take a deep breath and stay calm.

G. Having strength in numbers will help you survive.

Forgiving(原諒) someone who has hurt you or let you down is never an easy thing. Several new studies, however, say that it could have a lot of health benefits. When you think of forgiveness, you probably don’t think of it as being a health or medical problem. Studies from Stanford University, on the other hand, show that something like anger(憤怒) can change your well-being.

When cartoon book characters like the Incredible Hulk get angry, they change colors and often gain special power. In the real world, anger is less obvious and may be more dangerous. That’s why Professor Fred Luskin, founder of the Stanford Forgiveness Project and author of Forgive for Good, say holding on to anger and hatred(仇恨) can harm your physical and mental health. Two new studies seem to show the same idea. The studies find that people who are able to forgive feel less stress, less back pain, and less unhappiness. They also have fewer headaches, lower blood pressure and fewer problems on sleeping.

So it doesn’t matter if your anger is caused by the traffic or other things. Learning to let it go is important. Skills such as deep breath or thought can help. Or just ask yourself if it’s worth hurting yourself by staying angry with someone else.

Forgiveness doesn’t mean that you simply accept what happened and say it’s OK. Instead, it’s a way of making peace with yourself about what happened in the past.

1.The author of the passage tries to make his opinion clear ___________.

A. by showing his own examples B. based on his own experience.

C. by using some studies. D. by introducing some patients.

2.The example of the cartoon book characters in the passage is taken to ________.

A. support the opinion that anger and hatred harm your physical and mental health

B. introduce a famous expert

C. let the readers know the different colors of cartoon faces

D. show how to control one’s temper

3.The underlined phrase “ holding on to” in the passage possibly means_______.

A. taking away B. keeping up

C. getting rid of D. learning about

How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.

The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.

The toothbrush will be able to teach you to brush right (don’t forget the insides of the teeth!) and make sure you’re brushing long enough. “It’s kind of like having a doctor actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.

The toothbrush will also be able to talk to other applications(應(yīng)用) on your phone, so developers could, for example, create a game controlled by your toothbrush. You could score points for beating monsters(怪物) among your teeth. “We try to make it smart but also fun,” Serval says.

Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.

The company says the Kolibree will go on sale this summer, for $99 to $199, depending on features. The U.S. is the first target market.

Serval says that one day, it’ll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.

1.Which is one of the features of the Kolibree toothbrush?

A. It can sense how users brush their teeth.

B. It can track users’ school performance.

C. It can cause users’ fear of seeing a doctor.

D. It can help users find their phones.

2.What can we learn from Serval’s words in Paragraph 3?

A. You will find it enjoyable to see a doctor.

B. You should see your doctor on a day-to-day basis.

C. You can brush with the Kolibree as if guided by a doctor.

D. You’d like a doctor to watch you brush your teeth every day.

3.What is Paragraph 5 mainly about?

A. How Serval found out his kids lied to him.

B. Why Serval thought brushing teeth was necessary.

C. How Serval taught his kids to brush their teeth.

D. What inspired Serval to invent the toothbrush.

4.What can we learn about the future development of the Kolibree?

A. The brush handle will be removed.

B. A mobile phone will be built into it.

C. It will be used to fill holes in teeth.

D. It will be able to check users’ teeth.
