The brain is a remarkable part.It's responsible for thoughts and feelings.Now a new study finds that going through tough times as a kid also can have an impact.The adult brains of people who lived through lots of stress before the age of six—and then became depressed or anxious as teenagers—were different compared with adults who had an easier childhood.It seems that teens changed the shape of their brains by internalizing (使内在化) the stresses experienced years earlier.
Researchers already knew that the shape and size of a child's brain can change in response to lots of stress.They also knew that adults were more likely to be depressed if，as kids，they'd lived in poverty.Some studies showed that these depressed adults had unusual changes in their brain shape.But no one had tested if the early stress and later brain changes were linked.
Scientists in England studied almost 500 boys from birth until the ages of 18 to 21.Sarah Jensen is one of the new study's authors.Almost all of the boys her team studied experienced some hard times as kids.And，she concludes，“This is not necessarily harmful.”To some extent，that's just life.What can be dangerous，she says，is when children experience too many forms of difficulties.Her team's new data suggest that the tougher the childhood，the stronger the impact on the brain might be.
What's happening in the world around us relates to how we feel.Her team linked more childhood stress to more depression.Still，she notes，it's possible that if you find support for anxiety or depression，you might be able to prevent the changes seen here.“If you can change the environment，you can change the course of things，”Sarah says.So，she recommends，if teens develop anxiety or depression，it's good to ask for psychological doctors to give advice.

Tobacco is the second major cause of death in the world. It is responsible for the death of one in ten adults worldwide (about 5 million deaths each year). If current smoking patterns continue, it will cause some 10 million deaths each year by 2020. Half the people that smoke today, that is about 650 million people, will eventually be killed by tobacco.
Tobacco is the fourth most common risk factor for disease worldwide. The economic costs of tobacco use are equally devastating (破坏性的). In addition to the high public health costs of treating tobacco-caused diseases, tobacco kills people at the height of their productivity, depriving (剥夺) families of breadwinners(养家糊口的人) and nations of a healthy workforce. Tobacco users are also less productive while they are alive due to increased sickness. A 1994 report estimated that the use of tobacco resulted in an annual global net loss of 200 thousand million US dollars, a third of this loss being in developing countries.
Tobacco and poverty are closely linked. Many studies have shown that in the poorest households in some low-income countries as much as 10% of total household expenditure is on tobacco. This means that these families have less money to spend on basic items such as food, education and health care. It contributes to a higher illiteracy rate, since money that could have been used for education is spent on tobacco instead.

C. warn people of the harm of smoking
D. indicate the writer had a careful investigation
