Road traffic crashes kill million people each year worldwide. But the Word Health Organization (WHO) say they are preventable.
The report surveyed 180 countries, and it shows the number
of annual deaths from traffic crashes is stabilizing. [5]And that is good news the number of motor vehicles grows worldwide.
But the data also show that road crashes are the cause of death among young people aged 15 to 29. Young adults around the world are the worst driving risks. Even in the ., drivers aged 15 to 24 account for about 30 percent of all driving-related accidents.
The WHO report also finds a big gap in road safety and deaths between poor and rich countries. Poor countries have only 54 percent of worl d’s vehicles. But those countries have some of the worse safety statistics in the report.
‘‘Africa has only two percent of the word’s vehicles, but has the highest death rate on the road. ’’ That is what Etienne Krug, the head of the WHO Department of Non-communicable Diseases, says. Sweden, the Netherlands and the United kingdom are leaders in preventing traffic deaths. The highest death rates are in Africa and the Middle East.

Passage One
Some kinds of mental skills naturally decrease as people get older. [16]Yet research seems to show that some training can improve such skills. A recently published study also appears to demonstrate that the good effect of training can last for many years after that training has ended.
[17]Researchers at Johns Hopkins University in Maryland wanted to learn how long memory and thinking skills would last in older people who trained to keep them. The people were part of the ten-year research project. They were taught methods meant to improve their memory, thinking and ability to perform everyday tasks.
More than 2,800 volunteered for the study. Most studied when they were than 70 years old. The volunteers took one of several short training classes meant to help them keep their mental abilities. One class trained participants in skills including how to remember word lists. Another group trained in reasoning.[18]A third group received help with speed-of-processing-speed of receiving and understanding
information . A fourth group-the control group did not get any training.
Earlier results had established that the training helped the participants for up to five years .Now, lead study writer George Rebok says, [19] the research showed most of the training remained effective a full ten years later. Professor Rebok and his team found that the people trained in reasoning and speed-of-processing did better on tests than the control group. [19]They are wondering whether those effects which endured over time would still be there ten years following the training, and in fast, that’s exactly what they found.
16. What can improve mental skills according to the research
17. What was the purpose of Johns Hopkins Univer sity’s research
18. What does the term speed-of-processing refer to
19. What do we learn about the effects of most training Passage Two
Singapore has topped 131 cities globally to become the world’s most expensive city to live this year, ac-cording to the Economist Intelligence Unit. [20]The city’s strong currency combined with the high cost of running a car and
soaring utility bills contributed to Singapore topping the list. It is also the most expensive place in the world to buy clothes.
[21]Singapore replaces Tokyo, which topped the list last year. Other cities making up the top five most expensive cities to live in are Paris, Oslo, Zurich and Sydney, with Tokyo falling to sixth place. The EIU’s
Worldwide Cost of Living Survey is a relocation tool that uses New York City as a base. It looks at more than 400 individual prices. The editor of the report Jon Copestake said , improving sentiment in structurally expensive European cities combined with the continued rise of Asian cities means that that these two regions co ntinue to supply most of the world’s most expensive cities. But Asian cities also continue to make up many of the world’s cheapest, especially in the Indian areas.[22]Most Asian cities that top the list are there for mainly higher costs of groceries. Tokyo is still at the top of the list for everyday food items.
20.What contributed to Singapore being one of the world’s most expensive cities to live in
21.What city topped the list last year
22.What is the main reason that most Asian cities top the list
Passage Three
[23]According to new research by British scientists, teens who don’t smoke, drink only moderately or not at all, and who don’t eat much junk food tend to be happier than other teens. The study looked at 40,000 British households and came up with some interesting findings. For example, kids who never drank alcohol were up to six times more likely to report higher on happiness than kids who drank. And teens who smoked were five times less likely to rate high on happiness charts compared to kids who don’t s moke. Same goes for diet and physical activity. The more fruits and vegetables kids ate, and the more hours they spent playing sports, the happier they were.
Now, of course this doesn’t mean that not smoking or drinking, and playing sports guarantees happiness. [24]It could be that kids who have happy characters tend to be more active and less inclined to drink or smoke. And it could equally be the case that kids who are unhappy are more likely to drink and smoke and eat junk food, instead of the other way around.
[25]Other studies have shown that exercise is a proven way to fend off and treat anxiety and depression. Future studies may support the notion that other healthful behaviors, including keeping away from smoking, drinking, and eating too
much junk, can ward off sadness and boost happiness, too.
23. Who are more likely to be happier according to the study
24. What can we infer from the research
25. What is a proven way to get rid of anxiety
