原题: In 1948 the United States Secretary of States Dean Acherson ________ the Marshall Plan to aid the economic recovery of Europe after the Second World War.
(A) begin to carry out
(B) began carrying out
(C) beginning and carrying out
(D) to have begun carrying out
答案是:B
打完题才发现A的时态不对。又犯粗心的老毛病。。。。不过如果A是 began to carry out的话,是不是优先选A呢?
