In South Korea, television is also sent to mobile phones via satellite and terrestrial broadcast networks, which is far more (2)_____ than sending video across mobile networks; similar broadcasts will begin in Japan in April. Similar mobile-TV networks will also be built in Finland and America, and are being (3)_____ in many other countries.

And mobile TV was one of the big (8)_____ at the world’s largest technology fair, the Consumer Electronic Show.
(9)_____ all this activity, however, the (10)_____ for mobile TV are unclear. For a start, nobody (11)_____ knows if consumers will pay for it, though surveys suggest they like the idea. One (12)_____ agency of the field, says there will be 125m mobile-TV users by 2010, but many other mobile technologies inspired high hopes and then failed to (13)_____ up to expectations.

The (17)_____ for mobile TV is vast, in short, but (18)_____ is the degree of uncertainty over how it should actually be put into practice. Most observers do not expect widespread (19)_____ of mobile TV, if it comes at all, until 2008 at the earliest, since building the required ecosystem of technology, partnerships and content will (20)_____ some time.
选项
A、as if
B、even if
C、if only
D、if
答案
B
解析
逻辑衔接题。本句应为主从复合句,主句提到uncertainty in three areas,即在三个方面存在着不确定性,从句的大意是:人们确实想看移动电视,可以判断主从句有相反的意思,even if表示"即使",引导让步状语从句,符合句意。as if意为"似乎,仿佛",例:She looked as if she were made of ice.她看起来似乎是冰做的。if only"只要",如:if only I got invited, I would be glad to go.只要我被邀请,我一定会去。if"如果,倘若",引导条件状语从句,如:If I were to go,I would be late.倘若我去,就要迟到。
