【解析】D【命题动向】考查名词性从句。
解析一：It做形式主语，真实主语由后面的句子来充当。从主语从句的句子成分看，表示原因是最恰当的。句意为：那个人并没有早点儿报告这次事故，其原因还不清楚。
解析二：本题意为“不清楚为什么这个男人没有及早汇报这个事故。”it是本句的形式主语，why引导的从句是真正的主语，表示原因。B选项放在句中句意不通，C选项when表示一个时间点，不能和完成时连用。A选项that放在句中句意不通。

About a billion people in the world today are still facing the danger of malaria (疟疾) and nearly two million people die of the illness yearly, said Prof. Mare Gentilini of France in Agadir, according to local newspaper reports.
Fire swept from the kitchen through the Casino of the MGM Grand Hotel here just after dawn this morning, trapping about 3,500 guests and employees. Local officials said that more than 80 people were killed, most dying of smoke taking in above the 20th floor of the 26 - story hotel. At least two jumped to their deaths. Several hundred were injured.Cheektowage Central Middle School can be a lot of fun. It has game nights and student dances, after-school activities, and sports teams. However, students at the school must earn the right to join in the fun. If they don’t do their homework, participate in class, and behave at all times, they’re banned(禁止) from participating in after-school activities.
Students and parents say the threat of being excluded(排除在外) appears to be working. Kenny T. of Reno, Nev., says it taught him that actions have consequences: “I learned that I need to be balanced in both my work and athletics to be rewarded for working hard.” Parent Sondra LaMacchia told The New York Times that her 14-year-old daughter is learning responsibility at Cheektowaga Central. The teen used to perform poorly in her studies, but then she was banned from a school dance. The message got through loud and clear. “It’s nobody’s fault but hers,” LaMacchia said.
Although exclusion may help teach responsibility, some psychologists say it can also be threatening, especially for students who often cause, or may cause, trouble in school. They might become more aggressive and antisocial, which is exactly what schools like Cheektowaga Central want to prevent.
Should schools exclude students from activities to get them to behave? I believe teens need school activities and that inclusion can be the answer. For some troubled students, activities can be their motivation to stay in school. “Activities such as sports may be the only thing keeping certain students in school,” says Duace Wood, a teacher at Mohonasen High School in Rotterdam, N.Y. Getting involved in after-class activities keeps troublesome students in class. Even if they don’t do as well as their classmates, they are still learning. The more time they spend at school, the less time they have to even think about starting trouble. Teams also provide support and role models, and they help build the confidence that students need to succeed. If students who don’t behave are banned from activities, they might give up on school altogether.
