（1）“Beautiful day, isn't it?” “Yes. I wish we could go to the seaside today.” [《高中英语教科书》第二册(下), 人教社, p. 19]
[原译]“天气真好,不是吗?”“是的,我真希望我们今天能到海边。”(《高二英语英汉对照译注》,陕西师大出版社,p.256)
(2) I wish I could fly to the moon in a spaceship one day.
[原译]我希望有一天能乘宇宙飞船去月球。(《中学英语语法复习指南》,外研社,p.137)
(3) “I wish we could build a garage in the garden,” he said.
[原译]“我希望能在园子里建一个车库，”他说。（同上）
从上面的译文看，I wish (that) 完全等于 I hope (that)。是这样吗？
应当明确，I hope + (that)从句表示可以实现的愿望，而 I wish + (that)从句表示无法实现的愿望，也就是说，后一句型所表达的愿望是与事实相反的。因此，其宾语从句的谓语动词总是使用虚拟语气 (could, would, were, had done)。句(1)的语境告诉我们：说话人认为“在今天是不可能去海滨的”，因为他们居住的地方离海太远了。因此，I wish we could go to the seaside today. 仅仅表达一种无法实现的愿望，或者反过来说，是对现实的情景（不能去海滨）表示“遗憾”或“惋惜”。请注意下列各句中 wish + (that)从句所表达的反事实意义：
A. 表示与现在事实相反的愿望或与将来事实可能相反的愿望(即表示现在或将来无法实现的愿望)。
-
I wish that it would stop snowing. 要是雪停了该多好！（事实上天正在下雪）
-
I wish that it were morning. 我真希望现在是早晨。(事实上现在不是早晨)
-
I wish I were rich. 我要是很有钱就好了。
B. 表示与过去事实相反的愿望(即对既成事实表示遗憾或惋惜)。
-
Monica wished she hadn't come. 莫尼卡真希望她未曾来过。
-
I wish that I had never met him. 我真希望我从来没有遇见过他。
-
I wish we could have gone to the seaside yesterday. 要是昨天我们能去海滨就好了。（真遗憾，我们昨天没能去海滨。）
现在我们来翻译你所提问的三个英文句子：
（1）要是今天我们能去海滨就好了。（或：真可惜今天我们不能去海滨了。）
(2) 要是有一天我能乘宇宙飞船去月球,那该多好。
（3）要是我们能在园子里建一个车库就好了。（或：真可惜，我们不能在园子里建个车库。）
