試題分析：句意：當(dāng)我試圖去理解是什么阻擋了許多美國(guó)人得到他們應(yīng)有的快樂(lè)時(shí)，我發(fā)現(xiàn)個(gè)兩個(gè)原因。這是強(qiáng)調(diào)句型，其結(jié)構(gòu)是：It was+被強(qiáng)調(diào)部分+that/who（人）+其他。判斷強(qiáng)調(diào)句型的方法是把It was that這三個(gè)詞去掉，整個(gè)句子不缺成分，意思完整。這里被強(qiáng)調(diào)的是疑問(wèn)詞what，因?yàn)槭琴e語(yǔ)從句，所以強(qiáng)調(diào)句型應(yīng)該用陳述語(yǔ)序，what在從句中做主語(yǔ)，why不能做主語(yǔ)，故選C。
點(diǎn)評(píng)：本題難度適中。強(qiáng)調(diào)句型是高中階段的重難點(diǎn)之一，也是高考的熱點(diǎn)，需要考生有分析理解句子的結(jié)構(gòu)的能力。近幾年高考把強(qiáng)調(diào)句型與其他從句混合在一起考查更增加了試題的難度。
即學(xué)即練：It was after hegot what he had desired ____he realized it was not soimportant.
A.that      B.when       C.since        D. as
解析：A。句意：該句強(qiáng)調(diào)時(shí)間狀語(yǔ)從句after he got what he haddesired，題干意思是“得到他所夢(mèng)寐以求的東西后他才意識(shí)到一切都不那么重要”。不要誤選B。
