A、 China had about 1,100 e-commerce websites by the end of last March
B、 by the end of the first quarter of this year, China has had about 1,100 e-commerce websites
C、 by the end of this recent past March, China has about 1,100 e-commerce websites
D、 by the end of this first quarter, China had about 1,100 or so e-commerce websites

【正确答案】 A

【答案解析】[解析] 本题考查时态应用。句意为：通过一年的快速发展，到第一季度末，中国已有1100个电子商务网站。根据句意，句子时态应该是一般过去时，排除掉B和C。而且第一季度已经过去了，D中的this表示将要到来的，也应排除。故答案是A。
