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(痴呆). 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 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.

4.What can be inferred from the last paragraph?
A. Living near a main road adds to the risk of noise.
B. Living beyond 300 metres of a main road is safe for people.

Wilkie Collins was born in London in 1824 and his first novel -- a historical romance called“Anatonia” -- was published when he was 26. Shortly after this he met Charles Dickens, and they formed a close friendship that lasted for ten years and influenced both men's writing. Collins went on to publish 25 novels as well as many short stories, plays and works of non-fiction. However, he is most well known for the two mystery novels “The Woman in White” and “The Moonstone”.
Collins published both mysteries as serials in All the Year Round. When it appeared in the magazine in 1860, “The Woman in White” was so popular that it became the subject of a song and a play. It even influenced fashion, and many women started to dress in white. Eight years later “The Moonstone” was published and earned Collins the title "the father of the modern English detective novel". T S Elliot, another famous writer, said that The Moonstone was the "first and greatest of English detective novels", and it is still admired by modern crime writers today.
An author of many mysteries, Dorothy L Sayers considered “The Moonstone” to be "probably the finest detective story ever written", and many people agree with her. There are several reasons why they think so. One is that Collins uses different characters to tell each section of the story. The characters have very different personalities and voices, which are interesting and often amusing. There are also several features of the plot which started trends in mystery writing. For example, many detective stories are set in a country house, where the theft must have been committed by one of the people in the house. The character of a famous detective with an unusual appearance and habits occurs in many books, and an innocent person is often under suspicion at first. A number of modern films have also used the idea of a cursed jewel stolen from a religious statue. And of course, in The Moonstone and most other good mystery novels, the person who at first seems the least likely to be the criminal turns out to be guilty.

We are currently on a camp-site near Calais, on our way to the UK, and it is pouring with rain. As if gods want to prepare us for the UK at all costs. As if we don't know what rain is... Our ferry to the green isles will leave tomorrow at 10.30 and despite the rain, I am really looking forward to it.
It has taken us a while to get here, as we already left El Chorro on 4 April. After rushing through Spain in two days, however, we came to an inevitable slow-down when we entered France. Inevitable, as France has simply too much to offer for us. So as soon as we crossed the Pyrenees, our driving sequence became something like driving a few kilometres, visiting a castle, driving a few kilometres, taking pictures of a nice church, driving a few kilometres, having a quick peek at a fleas market, driving a few kilometres, visiting a museum etc. When we entered Brittany the real sightseeing started, in Vannes, in Lorient, in Brest and then on to Normandy: Le Mont St Michel, Bayeux and finally, finally the D-Day beaches. I always wanted to visit these, for obvious reasons I would say, but my father, realistic as he was, calculated the chances that it would rain a considerable amount of days of a three-week holiday and always decided against it. But a few days ago I finally stepped onto Gold Beach (where the Brits landed) and I was greeted by the Norman sun. A beautiful day.

Time flies! It is almost a year when I came to study in No. 1 Middle School. I remember when I first come to the school, everything was new to me. Now I have used to everything here and like my school very much. Asked how I like it so much. I’d like to let you to know I have good teachers as well as a good atmosphere to study in. My school has a long history. Three years ago, it celebrated their 100th anniversary. In recent years, great changes have taken place. Each classroom has been equipped with new multimedia equipments, which makes it possible for teachers to teach efficiently and students to learn easy. In the years to come, a new branch school will be on construction in the western area of the city, which is said to be completing by September in 2018, when it will have a better condition to welcome more students to receive a good education.

I was totally shocked to 
see the girls there, as they knew they were not allowed to go to the park alone. Obviously the girls 8.(hear) strange noises and then decided to run as fast as they could to get away. While 9.(run), Susie fell over and could not get up.
Susie’s mother and I had another talk with the girls about not wandering off without an adult then. Both of them learnt a 10.(value) lesson.
