(A) The development of a new jumbo rocket that is expected to carry the United States into its next phase of space exploration will be able to deliver a heavier load of instruments into orbit than the space shuttle and at a lower cost. (B) The development of a new jumbo rocket is expected to carry the United States into its next phase of space exploration and be able to deliver a heavier load of instruments into orbit at a lower cost than the space shuttle. (C) The new development of a jumbo rocket, which is expected to carry the United States into its next phase of space exploration, will be able to deliver a heavier load of instruments into orbit at a lower cost than the space shuttle. (D) A newly developed jumbo rocket, which is expected to carry the United States into its next phase of space exploration, will be able to deliver a heavier load of instruments into orbit than the space shuttle can, and at a lower cost. (E) A newly developed jumbo rocket, which is expected to carry the United States into its next phase of space exploration, will be able to deliver a heavier load of instruments into orbit than the space shuttle and to cost less. 选D 争议在E、D之间，很多大侠已经讨论过了，说E比的是rocket自身的cost，而D是比的是发射这一过程的cost更低，我的疑问是，怎么知道原句的意思，就是D而不是E？作者: cindy796 时间: 2010-8-25 13:24

我猜想句子的原意,即A选项，是deliver ..... at a lower cost，所以在DE二选一的时候选D。
