【解析】三段短文内容分别取材于人教版必修三Unit4、Unit 5和必修四Unit 1，要求学生对话题熟悉，有一定的语法分析能力。
（1）become “大爆炸”后好几十亿年过去了，但地球还只是一团尘埃。随后它会变成（become）什么没人能知道。 become在此处与其前不定式符号to一起构成表语，what it was to become在整句话中作主语，为主语从句。
（2）violent 地球变的激烈动荡（violent），不知道这个固体形状是否会继续存在下去。 violent adj. adj. 暴力的；猛烈的
（3）Going 向东走，你会经过山脉，成千上万的湖泊和森林，还有宽阔的河流和大城市。going eastward在此处作状语，由主语you主动发出，用现在分词形式。
（4）that 有些人的想法是，你可以在不到五天的时间里穿越加拿大，但是他们忘记了加拿大从海岸到海岸的5500公里的事实。that在idea之后引导同位语从句，并对其内容进行阐释说明。
（5）surrounded 人们说它（温哥华）是加拿大的最美丽的城市，被群山和太平洋环绕。 surrounded作后置定语，修饰city，与中心词city之间为被动关系，用过去分词。
（6）north 温哥华北部的海岸有一些世界上最古老、最美丽的森林。 north of Vancouver作后置定语，修饰中心词the coast。
（7）Only 她母亲头几个月来帮她的忙，这才使她得以开始自己的计划。 副词only修饰时间状语从句，表示强调。
（8）was 副词only + 状语从句放在句首时，主句要进行部分倒装。此处was she allowed为部分倒装结构，allow为及物动词，意为“她才得以允许开始自己的项目”，应为被动语态，用was。
（9）had 在那之前，每个人都认为黑猩猩只吃水果和坚果。由于时间状语为until then“到那时，在此之前”，think一词应为过去完成时，表示“过去的过去”，用had。
（10）work out 她还发现了黑猩猩是如何相互交流的，而她对它们身体语言的研究也帮助她了解了他们的社会体系。 work out弄懂，了解。用于help sb. do sth.（帮助某人做某事）结构，作宾语补足语，动词work用原形形式。
