【解析】三段短文內(nèi)容分別取材于人教版必修三Unit４、Unit 5和必修四Unit 1，要求學生對話題熟悉，有一定的語法分析能力。

【1】become “大爆炸”后好幾十億年過去了，但地球還只是一團塵埃。隨后它會變成（become）什么沒人能知道。 become在此處與其前不定式符號to一起構(gòu)成表語，what it was to become在整句話中作主語，為主語從句。

【2】violent 地球變的激烈動蕩（violent），不知道這個固體形狀是否會繼續(xù)存在下去。 violent adj. adj. 暴力的；猛烈的

【3】Going 向東走，你會經(jīng)過山脈，成千上萬的湖泊和森林，還有寬闊的河流和大城市。going eastward在此處作狀語，由主語you主動發(fā)出，用現(xiàn)在分詞形式。

【4】that 有些人的想法是，你可以在不到五天的時間里穿越加拿大，但是他們忘記了加拿大從海岸到海岸的5500公里的事實。that在idea之后引導同位語從句，并對其內(nèi)容進行闡釋說明。

【5】surrounded 人們說它（溫哥華）是加拿大的最美麗的城市，被群山和太平洋環(huán)繞。 surrounded作后置定語，修飾city，與中心詞city之間為被動關(guān)系，用過去分詞。

【6】north 溫哥華北部的海岸有一些世界上最古老、最美麗的森林。 north of Vancouver作后置定語，修飾中心詞the coast。

【7】Only 她母親頭幾個月來幫她的忙，這才使她得以開始自己的計劃。 副詞only修飾時間狀語從句，表示強調(diào)。

【8】was 副詞only + 狀語從句放在句首時，主句要進行部分倒裝。此處was she allowed為部分倒裝結(jié)構(gòu)，allow為及物動詞，意為“她才得以允許開始自己的項目”，應(yīng)為被動語態(tài)，用was。

【9】had 在那之前，每個人都認為黑猩猩只吃水果和堅果。由于時間狀語為until then“到那時，在此之前”，think一詞應(yīng)為過去完成時，表示“過去的過去”，用had。

【10】work out 她還發(fā)現(xiàn)了黑猩猩是如何相互交流的，而她對它們身體語言的研究也幫助她了解了他們的社會體系。 work out弄懂，了解。用于help sb. do sth.（幫助某人做某事）結(jié)構(gòu)，作賓語補足語，動詞work用原形形式。
