  • Study Warns of Heart Disease Danger From Dirty
    Air

2
Part ?
  • A new study shows that air pollution may be more
    of a risk for heart disease than scientists have
    thought. The research involved more than 65000
    women in the United States. Kristin Miller, a
    doctoral student at the University of Washington
    in Seattle, was the lead author of the study. She
    says the study showed that____________________.

disease risk was related not just to which city
a woman lived in, but also where in the city.
3
  • The study found that estimates of the effects of
    air pollution were often larger within cities
    than between cities. _________.The new findings
    lead some experts to suggest that current
    pollution limits may not be strong enough.

Yet averages between cities have served as the
main measure of the long-term effects of
pollutants.
4
  • The New England Journal of Medicine published the
    study. The scientists examined rates of heart
    attack, stroke and other cardiovascular events in
    women with long-term exposure to air pollution.
    ___________.

The cardiovascular system is the heart and all of
the passages that carry blood through- out the
body.
5
  • The study involved women over the age of 50 who
    had no sign of cardiovascular disease at the
    start of the research. The study followed the
    women for as long as nine years to see how many
    developed cardiovascular problems.

6
  • The researchers used information from a
    government project, the Women's Health
    Initiative. The researchers also examined levels
    of fine particles in the air in 36 areas across
    the country. That information came from the
    Environmental Protection Agency. The extremely
    small particles come from industrial smoke and
    traffic along with things like wood-burning
    fireplaces in houses.

7
  • In the study, every ten-microgram increase in
    pollution was linked to a 24 increase in the
    risk of a cardiovascular event. ____________.

But it was related to a 76 increase in the risk
of death from cardiovascular disease.
8
  • But just how do particles in the air damage the
    cardiovascular system? Douglas Dockery and Peter
    Stone at Harvard University in Massachusetts
    offer some theories in a related report. They say
    the particles may cause the lungs to swell and
    release chemicals from the pollutants into the
    blood. The chemicals then could damage the heart.

1.We can learn form the passage that Tim
Berners-Lee___________
  • was asked to write software for the World Wide
    Web in the 1980s.
  • did not expect his software to develop into the
    World Wide Web.
  • intended to invent something as big as the World
    Wide Web in 1980s.
  • wanted to make his memory substitute grow into
    something as big as the World Wide Web from the
    beginning.

2.We can infer from the passage that Tim
Berners-Lee___________
  • is a generous scientist.
  • is a little known hero of the information age.
  • has a poor memory.
  • cares nothing for money and fame.

v
3.The speaker thinks that Tim Berners-Lee_________
__
  • deserves more public recognition and more money
    from the Web.
  • Should get most of the money coming from the Web.
  • Is greatly wrong.
  • Is the greatest inventor of the information age.
