(A) likely to be at a severe disadvantage and is often unable to (B) likely severely disadvantaged and often unable to (C) liable to be severely disadvantaged and cannot often 这个为什么选A不选C呢?是liable的问题吗?我记得can 优于 be able to ...作者: weirui5621 时间: 2010-4-23 21:32
can 和be able to 的优先级是相同的
但can 能表示可能的意思,所以后面可以加被动,be able to 只能表示能够,后面不能加被动。
这题是liable 的问题作者: 木木OOO宝宝 时间: 2010-4-23 21:43
感谢帮助。可是liable 在这里不合适吗?作者: daier 时间: 2010-4-23 22:04
我记得这题好像liable和likely都可以,问题在于 1.be likely后面要加不定式to do 2.disadvantage做动词和at a disadvantage有差别,改变了原句意思
以上是我的看法,请大牛指教,呵呵作者: 木木OOO宝宝 时间: 2010-4-25 22:48
at a disadvantage 和 be disadvantaged 有什么区别呢?作者: ljwqlcl881703 时间: 2013-1-7 19:23
be disadvantaged 表示被损害OR处于不利地位 表意不明 be at a disadvantaged 只表示处于不利地位
