Electronic cigarettes are handheld nicotine-delivery devices that, despite a devoted following, are currently swirling in controversy. New York is pushing to become the first state to ban the devices, which so far remain【C1】______and mostly unstudied. With cute colors, fruity flavors, clever designs and other options, e-cigarettes may hold too much【C2】______for young people, critics warn, offering an easy gateway to nicotine addiction. But those criticisms clash with【C3】______strong arguments for the value of e-cigarettes. The devices, which are tobacco-free, may be a safer【C4】______to cigarettes, say advocates, who point to thousands of smokers who say they have used e-cigarettes to help them quit.
Electronic cigarettes【C5】______use a rechargeable battery-operated heating element to vaporize the nicotine in a replaceable pipe.

No tobacco is【C6】______in e-cigarettes and there is no smoke either. Instead, as users breathe in, they take in nicotine-filled vapor.

A)alternative B)engaged C)regular D)opaque

I)momentum J)equally K)replace L)unregulated
M)eliminate N)detect O)identified
【C9】
选项
答案
M
解析
空格处填入动词原形作句子谓语。本段首句提到,电子香烟带来的化学危害比普通香烟少得多,再结合上一句对烟草化学成分的描述,可以推断电子香烟危害低是因为“去掉”了烟草中的许多化学成分,eliminate符合上下文语义。
