问题
选择题
A lot of food as well as some tents _________to Yushu since the earthquake occurred.
A．has been transported
B．have been transported
C．is being transported
D．are transported
答案
答案：A
考查主谓一致及动词的时态和语态。as well as连接两个并列主语时，谓语动词和前一个主语保持一致，A lot of food是不可数名词，所以谓语动词用单数，排除B,D；根据时间状语since the earthquake occurred，可知句子要用现在完成时态，所以选A。
