非常感谢!

1)We have several countries to travel to. 2)We have several countries to travel. 老师，上面2句都正确吗？ 含义一样吗？谢谢。 上面哪一句等同于We have several countries to visit 呢？

We have several countries to travel.这是错误的。不定式与被修饰名词之间缺少了逻辑联系。介词to不可省略。

travel 可以是及物动词呀？ 我看到韦氏词典： [+ object] : to go through or over (a place) during a trip or journey They traveled the countryside. 可以说travel the USA 吗？

词典释义告诉你如果你go through or over the USA, 你就可以。问题是你是否由东向西横穿美国，或游遍美国，如果是那就可以。如果你仅仅在美国某个地方呆了几天，那就不可以。
