[语篇解读] 本文为应用文，报道了一起交通事故。
1．解析：句意：据报道，今天早上在罗马大街的拐角处发生了一起交通事故。“It be＋过去分词＋that”为固定句式，其中it为形式主语，that从句是真正的主语。
答案：that
2．解析：句意：没人知道当时究竟发生了什么。what引导宾语从句作saw的宾语，从句中缺少主语且表示事物，故用what引导。
答案：what
3．解析：句意：谁应对这一事故负责仍然在调查中。“__3__ will be responsible for the accident”为主语从句，该从句中缺少主语且表示“人”，故用who引导。
答案：Who
4．解析：句意：警察不能确定司机是否有罪。根据题干中的uncertain可知设空处表示“是否”，介词后不能由if来引导宾语从句，所以此处应用whether。
答案：whether
5．解析：句意：现在警察应做的就是他们必须弄清楚事故的起因。what引导主语从句，在从句中作do的宾语。
答案：What
6．解析：“__6__they must find out what led to the accident”为表语从句，该从句中结构完整，不缺少任何成分，所以用that引导。
答案：that
7．解析：句意：他们说他们很难下结论，因为事故是如何发生的还不清楚。根据句意可知设空处应为表示方式的连接副词how。
答案：how
8．解析：句意：也许是因为司机疲劳驾驶没能及时刹住车。The reason was that...
1
为固定句式，意思是“原因是??”。
答案：that
9．解析：句意：司机不承认他在拐角处超速驾驶。that引导同位语从句，解释fact的具体内容。
答案：that
10．解析：句意：警察怀疑他所说的话的真实性，决定作进一步的调查。doubted(肯定式)后面的宾语从句常用whether引导。doubt在否定句或疑问句中时，后面常用that来引导从句。
答案：whether
