选择题
Whether you believe it or not, it is ______that causes your illness.
A．because of your overweight
B．you are so overweight
C．because you are overweight
D．your being overweight
答案
答案：D
题目分析：不管你信或者不信,是你的肥胖引起了你的病.强调句型it is/was + 被强调东西 + that + 其他。本句考察动名词的被强调用法,被强调的是主语.因为that从句是接的第三人称单数的谓语,所以前面横线上是主语成分,只有动名词v-ing和动词不定式(这里没有)可以充当名词性成分,AC一般用作原因状语,选项B和下文即可独立构成完整句子,故选D.
