What is the psychology behind your mindless scribbles (涂鸦)? If your flower, for example, has a large circular center, _____ expresses confidence and the enjoyment of a good social life.
A.which B.as C.this D.such
C
【解析】考查代词。句意:信手涂鸦背后反映了什么心理?例如,如果你画的花朵有一个大大的圆心,这表明你充满自信,社交生活愉快。if引导条件状语从句,因此“____ expresses confidence and the enjoyment of a good social life”是主句,无须连词,which和as是连词,故A、B不正确;this指代上文提到的事情;such表示“诸如此类的人或事”。根据语境,故选C。
