【正确答案】
B
【答案解析】[解题思路] 名词固定搭配。固定搭配“have access to”意为“有权力或机会使用或接近……”,如:Students must have access to good books.(学生必须有机会读到好书。)
【答案解析】[解题思路] 语篇连贯。Provided that与Given that均表达假设,如:Given that I am healthy, I will take the task.(如果身体健康的话,我就承担这项任务。);In that也表达因果关系,表示某一方面的原因,多用于句中,如:China is different from America in that China has a long history.(中国不同于美国,因为中国历史悠久。)根据语篇,由于因特网的私有化,才导致了几个公司之间的竞争,因此选Now that表达因果关系,如:Now that the rain has stopped, we can go out.(雨停了,我们可以出去了。)
【答案解析】[解题思路] 动词辨析。transmit意为“传送,传递”,尤指信息的传送;transfer意为“转移,移交”,如transfer of power(权力移交);transform意为“转变”,如transform the economic system(转变经济制度);transport意为“交通,运输”。此处指网络间的信息传送,[A]为最佳选择。
