【答案解析】解析：结构搭配。"with+名词+分词短语"构成独立分词结构，在句中作状语，意为"随着…"。as是连词，不能引导独立分词结构；但可以引导时间从句。如本句改为as bombs are exploding in Baghdad，则也可以。
【正确答案】
B
【答案解析】解析：词义结构搭配。本句在谈论"对网上新闻的战时需求"，故应选demand。demand n.(for)对…的需求。report后不接for，故被排除。concern n.后可接 about，at，for，意为"对…的关心；挂念"，如：concern about his own affairs(对他自己的事关心)；concern at his misfortune(对他不幸的关切)；show concern for his safety(表示对他安全的关心)；the concerns of the nation(国事)。prospect n.前景；展望。
【正确答案】
C
【答案解析】解析：词义结构搭配。ability后常接不定式作定语。chance机会，可能性，与the test of在逻辑上不能搭配。此句意为"检验高速互联网连结的潜力"，故应选potential。power权力；电力，不合题意。
【答案解析】解析：词义搭配。embark on从事；贯彻。broadcast vt.广播。operate on给…做手术。capitalize on(=use sth. to one"s own advantage)利用某事(为达到某人利益)。
【正确答案】
D
【答案解析】解析：词义搭配。accessible adj.可进入的；有权得到的。desirable adj.想要的，令人满意的：a desirable job(令人满意的工作)。feasible adj.可行的。available adj.可得到的：the remarkable abundance of sounds and images available from video cameras(从录像机中得到的大量音像材料)。
