           专家说结果仍可能是投赞成票。
    e.g. If this is your first baby, it's far more likely that you'll get to the hospital too early...
           如果是第一胎，孕妇很有可能会过早地赶到医院。

2. 可能（做…）的；有（…）倾向的
    If someone or something is likely to do a particular thing, they will very probably do it.

    e.g. In the meantime the war of nerves seems likely to continue...
           与此同时，心理战似乎还可能继续。
    e.g. Once people have seen that something actually works, they are much more likely to accept change.
           一旦人们看到有些东西确实奏效，那他们可能会更容易接受变化。

3. 合适的；恰当的
    A likely person, place, or thing is one that will probably be suitable for a particular purpose.

    e.g. At one point he had seemed a likely candidate to become Prime Minister...

    e.g. We aimed the microscope at a likely looking target.

4. （尤用于回答他人）绝不可能，绝对不会
