MK二号是一颗几十亿公里外的行星,它在许多宗教里都是生命起源的地方。物理学家已经证明了它温和的气候和重力的牵引都和地球相似的理论;天文学家也通过卫星,在它的大气层里发现了氧原子和二氧化碳的存在,这些都是对生命来说,都是基本的。受到这一消息的鼓舞,生物学家们接着开始了研究以解开人们的迷惑——既然有了适合的条件,生命真的存在于这个星球吗?他们是通过下蛋,还是产仔来繁殖后代的呢?
上个月,一艘太空飞船被派到了那儿。可惜的是,这次任务失败了。不像地球,MK二号是一颗年轻得多的行星。因此,大团大团的有害酸云到处漂浮,引起猛烈的连锁反应的爆发。这些云团不仅阻挡了飞行员的视线,而且还损坏了发动机系统。幸运的是,飞行员小心注意,才及时阻止了飞船的坠毁。
15.A Journey across Canada
横穿加拿大的旅行
After a quiz last autumn, Kuang crossed the continent eastward to Toronto to visit his schoolmate, the distance measuring approximately 5,000 kilometers,
His train started from Vancouver, a city surrounded by mountains. After confirming his baggage was aboard the train, Kuang settled down in his seat. Having a gift for communication, he started chatting with another passenger within 5 minutes. Their topics included the Canadian traditions, the Prime Minister, the mixture of races, and the terrifying Great Fall. After a nice buffet at noon, he was pleased to find that the scenery was impressive. He saw beautiful harbours in the distance, wealthy urban areas and maple forest that covered thousands of acres. He even managed to catch sight of an eagle flying upward over bushes.
