　　1．As is known to us all，failure usually ________ laziness while diligence can ________ success.

　　A．results from；lie in　　 B．results in；result from

　　C．leads to；lie in D．results from；result in

　　2．-Can you explain ________ China's football team failed again in the attempt for the World Cup?

　　-I am sorry，but this is the last time.We will behave ourselves.

　　A．why is it that B．why it is that

　　C．how it is that D．how is it that

　　解析：考查强调句的特殊疑问句结构。根据答语，我们得知第一句话的句意为：你能否解释中国足球队为何又没能进入世界杯？特殊疑问句中只有疑问词可以强调，其强调结构是"疑问词＋is (was) it that...？"根据句意，是用why引导而不是how所以排除C、D两项。而且句中的强调句结构所在的句子是跟在动词"explain"后面作宾语从句，从句应用陈述语序，也就是"疑问词＋it is (was) that..."，故选B。

　　答案：B

　　3．We still don't know the exact time for the first human being ________.

　　A．to have been cloned B．being cloned

　　答案：D
