Ⅰ.阅读理解
(2017·海南省海口市第一中学月考)
Should every teenager be given a vaccine(疫苗)against the effects of
nicotine, and so prevent them becoming addicted to cigarettes?
This controversial possibility seems likely to happen in the future,
thanks to the development of a new vaccine for nicotine addiction. The
vaccine was designed for people who want to quit smoking but who repeatedly
relapse(复发).But since most countries are failing to cut the number of
children taking up smoking, many people will want to know whether the
vaccine should be used far more widely if it proves to be effective.
“The vaccine will be tested first on relapsing smokers, then on those
who plan to quit, then on those who are not yet completely addicted,”
says Frank Vocci of the National Institute of Drug Abuse. “The final step
would be vaccinating young people before they even try smoking, but that's
a long way down the road.”
John Roberts, medical director of British drug company Xenova, is very
enthusiastic. “I think prevention is a huge opportunity,” he says. “If
you can take away the pleasure nicotine gives, then teenagers who start
smoking are more likely to stop before it becomes a habit.”
80% of smokers start in their teens, with 360,000 teenagers and
children in the U.S. taking up the habit per year. But would the vaccine
be given to all teenagers or only a selected few? “It's hard to decide
which children are most at risk of becoming smokers,” says Amanda
Sandford of Action on Smoking and Health. Instead she favors education
as a way of discouraging children from smoking. Nabi Biopharmaceuticals
is also cautious, “It is very difficult to know what is the right age to
give the vaccine to children.”
There are also worries about giving the vaccine to long-term adult
smokers. Will addicted smokers simply try to beat the vaccine's
antibodies(抗体)by smoking more? Gary Norwith, Nabi's clinical director,
says this would be almost impossible. “You'd have to stick an entire pack
of cigarettes in your mouth and smoke for hours to beat the antibodies,”
he says.

2.What may Sanford agree with?
