expect sth.to do.固定短语,“期望某事发生”,sth. be expected to do.意为”某事有可能发生“。
make sth. clear to sb为固定搭配,意为“向某人阐明某事,使某人弄清某事”。
本句中make的宾语是where his failure lies 是被弄清楚,要用动词不定式的被动形式。
因此选C。

【点评】考查名词性从句,本题涉及主语从句和同位语从句。

强调句型的特殊疑问句式:疑问词(如what) is it that+其它,本句强调的是什么使得从前宏伟的宫殿蜕变的,所以用表示内容的what,选B【点评】考查主语从句和强调句,本题强调主语从句的引导词。
14.In the past decade, our education system too much on grades. However, grades have a direct connection with future success is still a question.A. focused; whetherB. focused; ifC. has focused; whetherD. has focused; if【答案】 C【解析】【分析】考查时态和主语从句。
根据In the past decade,在最近的几十年里,可知句子用现在完成时态,our education system是句子的主语,单数形式,所以第一空填has focused;第二空是主语从句做主语,if是否,不能引导主语从句,所以第二空填whether。
故选C。
【点评】主语从句主要有三类:1)(1)由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省。
例如:That you will win the medal seems unlikely.你想获得奖牌看起来是不可能的。
(2)用连词whether 引导的主语从句:whether有含义(是否),在句中不做成分,不可以省。
例如:Whether she is coming or not doesn't matter too much.她来不来都无关紧要。
