网考网参考答案：B
网考网解析：
本题要求填入确切的介词，与后面的the scientific world一起构成一个地点状语。B项 throughout指“遍及”，后接the scientific world时，意为“全科学界”，是正确答案。A项 through表示“通过；以……”不符合句意，C项over与a11连用时，表示“遍及”，因此也不能选用。D项on表示“关于”，与句意相差更远。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
