LSAT-21-1-4
4. Because quitting smoking is very stressful and
leads to weight gain, it is difficult to do. The
key to quitting however, may be as simple as
replacing an unhealthy activity with a healthy
one In one study half of those attempting to quit
were assigned to a smoking-cessation program
alone, and the other half were assigned to the
same program plus fifteen weeks of aerobic
exercise the one-month mark none in the first
group had quit but 40 percent of those in the
second group had not smoked.
Each of the following, if true, provides some
support for the argument EXCEPT:
(A) Regular exercise prevents weight gain
(B) Each group in the study included four hundred
randomly selected participants
(C) Nonsmokers accustomed to regular exercise do
not gain weight when they stop exercising
(D) Aerobic exercise can stimulate the brain's
production of endorphins. which reduce tension
(E) Of those in the second group in the study 38
percent had not smoked at the one-year mark.
答案C. 这个没问题。
但是E在说什么呀。 at the one-year mark 表示一年之内吗？怎么没看过这种用法。 |
