【1】考查連詞。句意：沒有人真正知道地球是如何開始形成的，根據(jù)意思可知填how。

【2】考查副詞。此處用副詞修飾動(dòng)詞accept，意為廣泛接受的，故填widely。

【3】考查介詞。此處為固定搭配begin with：以……作為開始，故填with。

【4】考查形容詞。此處隱含not……until的意思，直到……才，故此處用否定的形容詞，uncertain。

【5】考查連詞。此處是定語從句，從句缺少狀語，先行詞是表時(shí)間的，故用when，指代先行詞的時(shí)間概念。

【6】考查固定句型。此處為固定句型：so……that：如此……以至于，故填that。

【7】考查時(shí)態(tài)。此處強(qiáng)調(diào)動(dòng)作的一直在進(jìn)行，故用進(jìn)行時(shí)，填putting。

【8】考查動(dòng)名詞。From是介詞，后接動(dòng)名詞，故填escaping。

【9】考查連詞。句意：地球上的生命是否還會(huì)繼續(xù)生存百萬年取決于這個(gè)問題是否能夠解決。根據(jù)意思可填whether。

【10】考查語態(tài)。根據(jù)句意可知此處用被動(dòng)語態(tài)，問題是被解決的，填過去分詞solved。
