填空题
Men cannot manufacture blood as efficiently as women can. This
makes surgery riskier for men. Men also need more oxygen because they do not
breathe as often as women. But men breathe more deeply and this exposes them to
another risk. When the air is polluted, they draw more of it into their
lungs. A more recent and chilling finding is the effect of
automobile and truck exhaust fumes on children's intelligence. These exhaust
fumes are the greatest source of lead pollution in cities. Researchers have
found that the children with the highest concentration of lead in their bodies
have the lowest scores on intelligence tests and that boys score lower than
girls. It is possible that these low scores are connected to the deeper
breathing that is typical of the male. Men's bones are larger
than women's and they are arranged somewhat differently. The feminine walk that
evokes so many whistles is a matter of bone structure. Men have broader
shoulders arid a narrower pelvis, which enables them to stride out with no waste
motion. A woman's wider pelvis, designed for childbearing, forces her to put
more movement into each step she takes with the result that she displays a bit
of a jiggle and sway as she walks. If you think a man is brave
because he climbs a ladder to clean out the roof gutters, don't forget that it
is easier for him than for a woman. The angle at which a woman's thigh is joined
to her knees makes climbing awkward for her, no matter whether it is a ladder or
stairs or a mountain that she is tackling. A man's skin is
thicker than a woman's and not nearly as soft. The thickness prevents the suns
radiation from getting through, which is why men wrinkle less than women
do. Women also stay cooler in summer. The fat layer helps
insulate them against heat. Men's fat is distributed differently. And they do
not have that layer of it underneath their skin. In fact, they have considerably
less fat than women and more lean mass. Forty-one percent of a man's body is
muscle compared to thirty-five percent for women, which means men have more
muscle power. When it comes to strength, almost 90 percent of a man's weight is
strength compared to about 50 percent of woman's weight. The
higher proportion of muscle to fat makes it easier for men to lose weight.
Muscle bums up five more calories a pound that fat does just to maintain itself.
So when a man goes on a diet, the pounds roll off much faster.
For all men's muscularity they do not have the energy reserves women do. They
have more start-up energy, but the fat tucked away in women's nooks and crannies
provides a rich energy reserve that men lack. Cardiologists at
the University of Alabama who tested healthy women in treadmills discovered that
over years the female capacity for exercise far exceeds the male capacity. A
woman of sixty who is in good health can exercise up to 90 percent of what she
could do when she was twenty. A man of sixty has 60 percent left of his capacity
as a twenty-year-old. Questions: Complete the following sentences according to the passage, using a
